Cogeneration  

E-Print Network (OSTI)

The Public Utility Regulatory Policies Act ("PURPA") of 1978 was born out of the energy crisis of the 1970s. It reawakened the nearly dormant interest in industrial power generation and attached a new name, "cogeneration." PURPA has enabled cogeneration to develop and prosper in North America. Indeed, there is not an area of the industrial USA that has not been touched, and it is now spreading around the world.

Industrial - Utility Cogeneration Systems  

E-Print Network (OSTI)

Cogeneration may be described as an efficient method for the production of electric power in conjunction with process steam or heat which optimizes the energy supplied as fuel to maximize the energy produced for consumption. In a conventional electric utility power plant, considerable energy is wasted in the form of heat rejection to the atmosphere thru cooling towers, ponds or lakes, or to rivers. In a cogeneration system heat rejection can be minimized by systems which apply the otherwise wasted energy to process systems requiring energy in the form of steam or heat. Texas has a base load of some 75 million pounds per hour of process steam usage, of which a considerable portion could be generated through cogeneration methods. The objective of this paper is to describe the various aspects of cogeneration in a manner which will illustrate the energy saving potential available utilizing proven technology. This paper illustrates the technical and economical benefits of cogeneration in addition to demonstrating the fuel savings per unit of energy required. Specific examples show the feasibility and desirability of cogeneration systems for utility and industrial cases. Consideration of utility-industrial systems as well as industrial-industrial systems will be described in technical arrangement as well as including a discussion of financial approaches and ownership arrangements available to the parties involved. There is a considerable impetus developing for the utilization of coal as the energy source for the production of steam and electricity. In many cases, because of economics and site problems, the central cogeneration facility will be the best alternative for many users.

Cogeneration Planning  

E-Print Network (OSTI)

Cogeneration, the sequential use of a fuel to generate electricity and thermal energy, has become a widely discussed concept in energy engineering. American-Standard, a world-wide diversified manufacturing corporation, has actively been pursuing cogeneration projects for its plants. Of concern to us are rapidly escalating electrical costs plus concern about the future of some utilities to maintain reserve capacity. Our review to date revolves around (1) obtaining low-cost reliable fuel supplies for the cogeneration system, (2) identifying high cost/low reserve utilities, and (3) developing systems which are base loaded, and thus cost-effective. This paper will be an up-to-date review of our cogeneration planning process.

UNITAR boosts cogeneration for heavy crude production  

SciTech Connect

The UNITAR/UNDP Information Center for Heavy Crude and Tar Sands publicized the favorable effect of cogeneration on the economics of generating steam for in situ recovery of heavy oil. Although cogeneration of electricity with the production of steam for heavy crude production is a rapidly growing activity in California, it is still unknown in other countries where heavy crude is produced. The study concentrated on two specific cases: a heavy crude cogeneration plant in Kern County in California and a heavy crude production plant at Wolf Lake in Alberta, Canada. A comparison of the two cases showed that due to the specific conditions in California, cogeneration can reduce, in this specific case, the cost of production of heavy crude by $4.80 per barrel whereas in the case of Wolf Lake, cogeneration would not be economic (electricity prices in relation to natural gas prices are much lower in Canada). One of the purposes of the UNITAR study was to direct attention in other countries producing heavy crude to the advantages of cogeneration.

The Integration of Cogeneration and Space Cooling  

E-Print Network (OSTI)

Cogeneration is the production of electrical and thermal energy from a single fuel source. In comparison, electric power generation rejects the useful heat energy into lakes or other heat sinks. Electric generation alone provides approximately 30 percent of its prime energy for useful end-use energy, while cogeneration makes approximately 80-85 percent of its prime energy source available for useful work (Figure A). The application of the thermal energy is critical to the economic analysis of a cogeneration project since nearly two-thirds of the energy and economic savings are produced by the hot water and/or exhaust gases. Finding a productive and economical application for the thermal energy is extremely important.

Opportunity for cogeneration  

Science Conference Proceedings (OSTI)

The Lethbridge Regional Hospital is a 264-bed acute care center that offered an excellent opportunity to use a cogeneration system to provide a substantial portion of the hospital`s electrical and steam requirements. Cogeneration is the cost-effective production of two useful forms of energy using a single energy source. The Lethbridge Regional Hospital cogeneration plant produces electrical energy and heat energy using natural gas as the single energy source. The cogeneration project has helped the facility save money on future utility bills, lowered operating costs and produced a cleaner source of power.

Industrial cogeneration optimization program  

SciTech Connect

The purpose of this program was to identify up to 10 good near-term opportunities for cogeneration in 5 major energy-consuming industries which produce food, textiles, paper, chemicals, and refined petroleum; select, characterize, and optimize cogeneration systems for these identified opportunities to achieve maximum energy savings for minimum investment using currently available components of cogenerating systems; and to identify technical, institutional, and regulatory obstacles hindering the use of industrial cogeneration systems. The analysis methods used and results obtained are described. Plants with fuel demands from 100,000 Btu/h to 3 x 10/sup 6/ Btu/h were considered. It was concluded that the major impediments to industrial cogeneration are financial, e.g., high capital investment and high charges by electric utilities during short-term cogeneration facility outages. In the plants considered an average energy savings from cogeneration of 15 to 18% compared to separate generation of process steam and electric power was calculated. On a national basis for the 5 industries considered, this extrapolates to saving 1.3 to 1.6 quads per yr or between 630,000 to 750,000 bbl/d of oil. Properly applied, federal activity can do much to realize a substantial fraction of this potential by lowering the barriers to cogeneration and by stimulating wider implementation of this technology.

Cogeneration - A Utility Perspective  

E-Print Network (OSTI)

Cogeneration has become an extremely popular subject when discussing conservation and energy saving techniques. One of the key factors which effect conservation is the utility viewpoint on PURPA and cogeneration rule making. These topics are discussed from a utility perspective as how they influence utility participation in future projects. The avoided cost methodology is examined, and these payments for sale of energy to the utility are compared with utility industrial rates. In addition to utilities and industry, third party owner/operation is also a viable option to cogeneration. These options are also discussed as to their impact on the utility and the potential of these ownership arrangements.

Cogeneration for resort hotels  

Science Conference Proceedings (OSTI)

Resort Hotels should be considered for application of co-generation to take advantage of higher thermal efficiency and consequent energy cost avoidance. Modern resort hotels require comfort and reliability from mechanical and electrical systems on an around the clock basis. Load profiling reveals simultaneous process heating and electricity use requirements that aid in the selection and sizing of co-generation equipment. Resort Hotel needs include electrical loads for lighting, fan motors, elevators, escalators and receptacle uses. Process heat demands arise from kitchen, servery, banquet, restaurant, laundry, and bakery functions. Once the loads requiring service have been quantified and realigned (shifted) to maximize simultaneous demands the engineering task of co-generation application becomes one of economics. National legislation is now in place to foster the use of co-generating central utility plants. Serving utility companies are now by law required to buy back excess energy during periods of reduced hotel demands. Resort Hotel loads, converted into electricity and heat demands are tabulated in terms of savings (positive cash flow) or costs (negative cash flows). Cash flow tabulations expressed in graphs are included. The graphs show the approximate simple payback on initial costs of co-generation systems based on varying electricity charges.

Cogeneration Operational Issues  

E-Print Network (OSTI)

A great deal of the discussions concerning congeneration projects are focused on the "avoided cost" and other legal issues which effect these projects. These areas are extremely important and are essential to the success of the venture. Equally important, however, are the operational Issues which impact the utility and the cogenerator. This paper addresses the utility perspective in regard to possible impact of cogeneration systems on utility service to other customer, safety and substation operations. Other operational issues also include utility transmission planning, generation planning and fuel mix decisions. All of these operational problems have an impact on the ratepayer in regard to quality of electric service and future rates. Both the cogenerator and the utility have an interest in solving these problems.

Cogeneration Project Analysis Update  

E-Print Network (OSTI)

Not long ago, to evaluate the feasibility of a cogeneration project, a simple economic analysis, that considered capital required, operations and maintenance savings, was sufficient. However, under present economic uncertainties (and highly competitive business environment) the situation has changed dramatically. It is now essential to do an in-depth evaluation to insure that very diverse and applicable factors are determined and properly evaluated. This paper will go beyond the "nuts and bolts" analysis of cogeneration economics. It will enumerate and discuss diverse factors, such as, but not limited to: Fuel Considerations, Heat System Analysis, Electric Power Considerations, Key Technical Project Considerations, and Economic Analysis.

Cogeneration Economics for Process Plants  

E-Print Network (OSTI)

This paper presents the incentives for cogeneration, describing pertinent legislation and qualification requirements for cogeneration benefits, and indicates the performance and economic characteristics of combined cycle cogeneration applications. The Fuel Use Act (FUA) restricts the use of un-renewable or premium fuels (e.g., natural gas and oil) for high-load-factor or base-load power generation. The Public Utility Regulatory Policy Act (PURPA) encourages high-efficiency cogeneration by providing exemptions to the restrictions and requiring that utilities purchase cogenerated power at rates corresponding to the costs they "avoid" by not generating this power.

The commercial or industrial firm contemplating cogeneration at its facilities faces numerous basic design choices. The possibilities exist for fueling the system with waste materials, gas, oil, coal, or other combustibles. The choice of boiler, engine, turbine, generator, switchgear, and balance of plant can be bewildering. This paper presents an overview and a systematic approach to the basic system alternatives and attributes. The presentation illustrates how these options match the electrical and thermal needs of a firm, and what kind of operating economics and system paybacks have been achieved. Several cogeneration options are also illustrated to eliminate the problems and uncertainties of dealing with uninterested or non-cooperative utilities, as well as to minimize system costs.

Cogeneration is the sequential use of a single fuel source to generate electrical and thermal energy. It is not a new technology but an old, proven one whose interest has been reawakened. American Standard has had concerns regarding electrical pricing to our facilities as well as reserve generating capacity margins of some electrical utilities. Because of these concerns, we have been reviewing the potential of cogeneration at some of our key facilities. Our plan is to begin with a Pilot Plant 500 KW steam turbine generator to be installed and operating in 1986. Key points to be discussed in the paper are: 1. Relationship with outside parties, i.e., state agencies and the utility, regarding the project. 2. Engineering of the System. 3. Economics of the Project.

If designed properly, a steam turbine co-generation (producing heat and power simultaneously) system can increase energy efficiency, reduce air emissions and qualify the equipment for a Capital Cost tax Allowance. As a result, such a system benefits the stakeholders, the society and the environment. This paper describes briefly the types of steam turbine classified by their conditions of exhaust and review quickly the fundamentals related to steam and steam turbine. Then the authors will analyze a typical steam turbine co-generation system and give examples to illustrate the benefits of the System.

MIT: $avings through cogeneration  

SciTech Connect

The Massachusetts Institute of Technology has installed an `inside-the-fence` cogeneration plant as a way of controlling costs for their increasing electric power and steam requirements. The cogeneration system fits neatly on one side of the campus power plant, with the GT10A gas turbine in an enclosure. The generator is located on one end, the HRSG to the side. On the instrument/control side, the gas turbine is equipped with a Westinghouse DCS control system. A Horriba emission monitoring system keeps track of pollution. Power in excess of the 22 MW produced by the gas turbine-generator must be purchased from the local utility. As requirements rise in future years, this could become more common, which may lead MIT, in 4-5 years, to convert to a combined cycle system. The steam-generating capabilities of the HRSG are adequate for the addition of a 10-MW backpressure steam turbine, should they make this decision. 3 figs.

Baytown Cogeneration Project  

E-Print Network (OSTI)

The Baytown Cogeneration Project installed a GE 7FA gas turbine generator that produces 160 MW of electricity and 560-klB/hr of superheated 1500-psig steam. All of the steam and electricity are consumed by the ExxonMobil Refinery & Chemical Plant Complex. Small sales of electricity are possible in winter months. The new Cogen Unit allowed the complex to shutdown three inefficient, 1960’s vintage, steam and electricity generators to improve steam and power generation efficiency and to reduce environmental emissions. The 1500-psig steam generated by Cogen reduces the firing on the conventional boilers which are used in the olefins plant to drive extraction/condensing steam turbines. The lower pressure extracted steam is both used within the olefins plant and exported throughout the refining/chemicals complex.

Cogeneration Economics and Financial Analysis  

E-Print Network (OSTI)

Cogeneration has received much attention as a way to improve the efficiency of energy generation and conversion. This interest has been stimulated by higher energy costs for fuel and electricity as well as economic incentives granted by the federal government for industrial cogeneration. This paper discusses a variety of cogeneration systems applied at specific sites drawn from the major industrial sectors - food, textiles, pulp and paper, chemicals, and petroleum refining. Various technologies are considered. Capital and operating cost estimates are developed for the most promising systems to calculate cash flows and determine return on investment for a industrial ownership options of these facilities. Conclusions summarize the relation between technology, relative electric energy costs, and fuel costs.

Optimal Scheduling of Cogeneration Plants  

E-Print Network (OSTI)

A cogeneration plant, feeding its output water into a district-heating grid, may include several types of energy producing units. The most important being the cogeneration unit, which produces both heat and electricity. Most plants also have a heat water storage. Finding the optimal production of both heat and electricity and the optimal use of the storage is a difficult optimization problem. This paper formulates a general approach for the mathematical modeling of a cogeneration plant. The model objective function is nonlinear, with nonlinear constraints. Internal plant temperatures, mass flows, storage losses, minimal up and down times and time depending start-up costs are considered. The unit commitment, i.e. the units on and off modes, is found with an algorithm based on Lagrangian relaxation. The dual search direction is given by the subgradient method and the step length by the Polyak rule II. The economic dispatch problem, i.e. the problem of determining the units production giv...

Price incentives of industrial cogeneration  

Science Conference Proceedings (OSTI)

One of the strategies of current national energy policy is to promote the combined production of electricity and steam at industrial sites. The impact of relative electricity and fuel prices on the decision to cogenerate is examined here. The strategy of the study is to compare the costs of two firms that are identical except for the way they acquire electricity: one firm purchases electricity while the other cogenerates. Using this framework, the relationship between the elasticity of the price of electricity with respect to the price of fuel and the parameters of the production function is shown to be a key to the decision to cogenerate. Some preliminary empirical estimates of this relationship are also presented.

INJECTIVE COGENERATORS AMONG OPERATOR BIMODULES  

E-Print Network (OSTI)

Abstract. Given C ?-algebras A and B acting cyclically on Hilbert spaces H and K, respectively, we characterize completely isometric A, B-bimodule maps from B(K, H) into operator A, B-bimodules. We determine cogenerators in some classes of operator bimodules. For an injective cogenerator X in a suitable category of operator A, B-bimodules we show: if A, regarded as a C ?-subalgebra of A?(X) (adjointable left multipliers on X), is equal to its relative double commutant in A?(X), then A must be a W ?-algebra. 1.

The Developer's Role in the Cogeneration Business  

E-Print Network (OSTI)

Although cogeneration technology is well-established, the business is new and still taking shape. Cogeneration projects involve a diverse mix of organizations, including equipment suppliers, engineering and construction firms, fuel suppliers, operators, financiers and regulatory agencies. Because of this complexity, an increasing number of projects are being sponsored by cogeneration developers, who design, construct, own and operate the facilities. The benefits energy users gain from third-party developed cogeneration projects and how the developer brings together these groups to effectively implement cogeneration projects will be described.

NISCO Cogeneration Facility  

E-Print Network (OSTI)

The NISCO Cogeneration facility utilizes two fluidized bed boilers to generate 200 MW of electricity and up to 80,000 LBS/HR of steam for process use. The partnership, of three industrial electricity users, Citgo, Conoco, and Vista Chemical, and the local utility, Gulf States utilities, was formed in the late 1980's. In August and September 1992 two fluidized bed boilers were brought into operation to repower existing turbine generating equipment. The fluidized bed units were designed to utilize 100 percent petroleum coke, a locally produced fuel. Petroleum coke is a high heating value, low volatile, high sulfur fuel which is difficult to utilize in conventional boilers. It is readily available in most areas throughout the world, including North and South America. Because of superior environmental performance, lower capital cost, and fuel versatility, circulating fluidized bed boilers were selected to repower the existing turbines. Fluidized bed boilers were ideally suited for a repowering application. Existing equipment matched or was modified for utilization in the project optimizing capital cost. The fluidized bed boilers, designed and fabricated by Foster Wheeler, are each capable of producing 825,000 LBS/HR of steam. This paper describes the results attained at NISCO during the first full year of operation. The design attributes of the project which enabled a successful and efficient unit startup are explained. Descriptions of design enhancements and modifications installed during the first year to improve the operability of the repowered facility are included. This paper describes technology and experiences of value to those considering steam generating unit repowering or construction.

EPRI Cogeneration Models -- DEUS and COPE  

E-Print Network (OSTI)

In the Fall of 1978, the Electric Power Research Institute (EPRI) initiated a program for the design and evaluation of alternate cogeneration systems. The primary objective of the study is to analyze the overall system value of cogeneration. A portion of the study involved the development of a simulation model for evaluation of cogeneration systems on a site specific basis. Dual Energy Use Systems (DEUS) model contains an extensive data base with which to cost and size many different cogeneration systems and compare them with the no-cogeneration system for the same process. A financial and institutional model has been developed to follow the after tax cash flows from the attractive cogeneration configurations identified in DEUS. The financial model, Cogeneration Options Evaluation (COPE), is designed to consider the financial and regulatory implications for the utility, the industry and where relevant, third parties, for all practically feasible combinations of ownership.

Simulation aids cogeneration system analysis  

Science Conference Proceedings (OSTI)

Cogeneration systems using gas turbines and heat-recovery steam generators (HRSGs) are widely used in chemical process industries (CPI) plants. Because these plants are quite expensive and the HRSG is an important part of the system, it is prudent to analyze the heat-recovery system or simulate its performance well in advance of finalizing plant specifications. Simulation is a method of predicting the performance of the HRSG under different operating modes and gas and steam conditions without physically designing the equipment. Such a study will provide the engineer with valuable information about the HRSG and its performance capabilities. The simulation results could influence the choice of steam system parameters and the selection of the steam or gas turbine. In addition, one may also obtain information about the performance of the HRSG and the cogeneration system. This article explains what HRSG simulation is and the basic methodology. Its applications are then illustrated through several examples.

A Regulator's View of Cogeneration  

E-Print Network (OSTI)

The Pennsylvania Public Utility Commission regulates essentially all types of public utilities and has the authority to investigate issues of public interest. To establish a point of reference, Pennsylvania's utilities contribute about 5 percent of the total national electric generation. In view of the energy requirements of Pennsylvania's industry and the impact of increasing energy costs on employment the Commission directed its technical staff to investigate the potential for industrial cogeneration and a pricing formula consistent with the electric utilities' costs. The Commission's technical staff has completed proposed regulations to implement the provisions of the Public Utility Regulatory Policies Act (PURPA) Section 210 concerning small power producers. The regulations incorporate suggestions from both potential producers and utilities. Staff has devised a strategy for utility purchases of energy and capacity which should be of interest to regulators in other jurisdictions, encourage potential cogenerators and satisfy utilities.

Superposition, A Unique Cogeneration Opportunity  

E-Print Network (OSTI)

Industrial steam systems provide opportunities for the economic cogeneration of heat energy and shaft power. Progressive plant owners and managers have utilized these potentials. Too often opportunities are not exploited. A plant that is expanding, is being substantially modernized, or is converting from petroleum fuels to coal, should carefully examine cogeneration design options. Depending on the thermodynamic condition of throttle steam for its major turbines, a high pressure/temperature power plant may be SUPERPOSED on the existing plant. Extraction/backpressure turbogenerators can exhaust into retained high performance turbines and to process steam loads. They will produce high value, favorably priced power for in-plant use and/or sale to the franchised utility. The concepts are not new, but increasing tendencies to fuel conversion and the combining of cycles should prompt unique applications. Microcomputer modeling and systems analyses are used to develop examples.

Why Cogeneration Development Projects Fail  

E-Print Network (OSTI)

Cogeneration projects that are organized by developers fail to reach fruition for reasons other than the basic economical or technical soundness of the opportunity. Cogeneration development projects fail because of misunderstanding by the host or other participants of their obligations, inadequate management support by the host organization, regulatory changes, environmental difficulties, overly high expectations of profit, changes in fuel economics, utility policy changes, changing financial markets, and a variety of other issues. Each of these potential problem areas will be discussed briefly, examples will be given, and remedies will be suggested. Most of these potential problems then can be either avoided or attenuated by advanced provisions so that they will not become fatal flaws to project completion.

Cogeneration development and market potential in China  

Science Conference Proceedings (OSTI)

China`s energy production is largely dependent on coal. China currently ranks third in global CO{sub 2} emissions, and rapid economic expansion is expected to raise emission levels even further in the coming decades. Cogeneration provides a cost-effective way of both utilizing limited energy resources and minimizing the environmental impacts from use of fossil fuels. However, in the last 10 years state investments for cogeneration projects in China have dropped by a factor of 4. This has prompted this study. Along with this in-depth analysis of China`s cogeneration policies and investment allocation is the speculation that advanced US technology and capital can assist in the continued growth of the cogeneration industry. This study provides the most current information available on cogeneration development and market potential in China.

On-site cogeneration for office buildings  

SciTech Connect

The purpose of this project was to investigate the feasibility of alternative means of enhancing the economic attractiveness of cogeneration for use in office buildings. One course of action designed to achieve this end involves directing the exhaust heat of a cogeneration unit through an absorption chiller to produce cooling energy. Thus, the units could be operated more continuously, particularly if thermal storage is incorporated. A second course of action for improving the economics of cogeneration in office buildings involves the sale of the excess cogenerated waste heat. A potential market for this waste heat is a district heating grid, prevalent in the downtown sections of most urban areas in the US. This project defines a realistic means to guide the integration of cogeneration and district heating. The approach adopted to achieve this end involved researching the issues surrounding the integration of on-site cogeneration in downtown commercial office buildings, and performing an energy and economic feasibility analysis for a representative building. The technical, economic and legal issues involved in this type of application were identified and addressed. The research was also intended as a first step toward implementing a pilot project to demonstrate the feasibility of office building cogeneration in San Francisco. 13 refs., 7 figs., 4 tabs.

Design Considerations for Large Industrial Cogeneration Systems  

E-Print Network (OSTI)

Cogeneration systems have been contributing to the profitability of many industrial plants for years. However, with the renewed interest in energy and conservation as the cornerstone of the National Energy Act, it is important that the alternatives available to fully exploit this technology be fully understood. This paper will review the considerations required to develop meaningful cogeneration systems. Turbine types, ratings, steam conditions and other parameters will be discussed and their impact on economics will be illustrated. Furthermore, the influence of tax incentives on the economics of cogeneration systems will be explored.

Cogeneration Can Add To Your Profits  

E-Print Network (OSTI)

The predicted rapid escalation of gas and electric costs, particularly in those utility systems predominantly fired by gas, make it important for both industry and utilities to evaluate the role of cogeneration in their future plans. Industries requiring a continuous supply of steam and with fuel available at a cost not significantly higher than the utility will usually find that cogeneration with its higher fuel effectiveness can offer a significant saving in their costs of steam and powers at a return on investment above their required 'hurdle rate.' Also, cogeneration can offer important advantages to utilities, particularly those faced with the need to increase near term capacity but uncertainty as to the long term load growth. Cogeneration plants have a permit/construction period of two to three years and are rarely over 100 MW in size. To the extent sizable continuous steam loads are present in the utility system, cogeneration alleviates the uncertainty in projecting the need conventional large utility plants, adds efficient capacity in smaller increments and if jointly or wholly owned by industry reduces the capital costs to the utility. The PURPA regulations, with their procedures for calculating avoided cost, limit the benefits the utility and their customers can directly receive from industrially-owned cogeneration. They can share in the benefits if they are adequate to permit industry to receive a reasonable savings and return on their investment and a contract is negotiated to permit the utility and its customers to receive the remainder. Under the present PURPA, the utility can own up to 50% of a cogeneration plant and under this ownership arrangement, the utility and its customers can directly receive the benefits of cogeneration. When is cogeneration advantageous and what are the interactions between the industrial sites' energy requirements, the cogeneration plant configuration and its economics? Economics are the 'bottom line' in determining the potential for installing a cogeneration plant. In this paper, the performance and cost characteristics of various types of cogeneration plants, with emphasis on gas turbine plants, will be described together with their matching to the site energy requirements and the effect that these interactions together with fuel cost and electric power rates have on the economic benefits

Thermal energy storage for cogeneration applications  

SciTech Connect

Cogeneration is playing an increasingly important role in providing energy efficient power generation and thermal energy for space heating and industrial process heat applications. However, the range of applications for cogeneration could be further increased if the generation of electricity could be coupled from the generation of process heat. Thermal energy storage (TES) can decouple power generation from the production of process heat, allowing the production of dispatchable power while fully utilizing the thermal energy available from the prime mover. The Pacific Northwest Laboratory (PNL) leads the US Department of Energy's Thermal Energy Storage Program. The program focuses on developing TES for daily cycling (diurnal storage), annual cycling (seasonal storage), and utility applications (utility thermal energy storage (UTES)). Several of these technologies can be used in a cogeneration facility. This paper discusses TES concepts relevant to cogeneration and describes the current status of these TES systems.

Cogeneration- The Rest of the Story  

E-Print Network (OSTI)

Everyone is praising the daylights out of cogeneration these days. And while it may be the best energy system design, there are numerous questions that should be asked before anyone jumps on the bandwagon. We are not seeing enough sobriety and good old engineering conservatism. Since when are we designing systems without checking our assumptions? Where have professionalism, ethics and care gone? Why is it that only five of the past 100 cogeneration evaluations we reviewed were conservative and fair representations? This paper illustrates a step-by-step approach to checking the accuracy of a cogeneration project. Illustrations of typical errors and their consequences are also developed. Potential industrial and commercial users should find this list helpful in evaluating requests for proposals (RFPs). Electric and gas utilities could use this list to assist customers when looking closely at cogeneration. And regulators and their staffs should consider the potential for unscrupulous tricks and traps to be played on unsuspecting or naive buyers.

HL&P/Du Pont Cogeneration Project  

E-Print Network (OSTI)

The HL&P/Du Pont Cogeneration Project is an arrangement between Houston Lighting & Power Company and E. I. Du Pont de Nemours whereby the utility-owned cogeneration facility supplies a portion of the Du Pont process steam requirements. The facility consists of two cogeneration systems, each comprised of a natural gas fired GE 80 MW Frame 7EA, or equivalent, exhausting into a heat recovery steam generator (HRSG). Gas turhines are equipped with steam injection capability for power augmentation. Supplementary fireable HRSG's provide additional supply reliability for the steam host. Electricity from the project is delivered into HL&P's System through a new 138 KY substation. Such an arrangement offers Du Pont a significant cost saving opportunity as less efficient steam raising equipment is displaced. It also provides HL&P ratepayers with significant benefits, given the fuel efficiencies associated with cogeneration projects.

Bayou Cogeneration Plant- A Case Study  

E-Print Network (OSTI)

The Bayou Cogeneration Plant is a prime example of the high fuel efficiency and consequent energy savings an industrial company can realize from cogeneration. A joint venture of Big Three Industries, Inc., and General Electric Company, this $100 million power plant became operational late last year and produces approximately 1.4 million lb/hr of process steam and 300 MW of electricity. As the turnkey supplier, General Electric was responsible for the entire project from cycle engineering through start up and is currently operating and maintaining the plant. This paper describes the factors which led Big Three Industries to build a cogeneration power plant and the route selected for project implementation. Also included is a brief profile of project implementation, highlighting the responsibilities of the turnkey supplier and specific steps taken to compress the project into a 20-month schedule, resulting in significant cost savings and enabling Big Three to realize cogeneration benefits as early as possible.

Design and Evaluation of Alternative Cogeneration Systems  

E-Print Network (OSTI)

In the fall of 1973, the Electric Power Research Institute (EPRIY initiated a program for design and evaluation of alternate cogeneration systems. The primary objective of the study is to analyze the overall system (industry and utility) value of cogeneration. A state-of the-art assessment of cogeneration was initiated, in which 17 cogeneration systems were studied in detail. Following the Completion of the case studies, project definition was begun to determine preferred cogeneration systems. From this activity a screening model was developed. The model will be linked to existing methodology to assess the question of capacity credit. Concurrent to the development of the model are a series of cogeneration conceptual designs. The first of these have been completed for pulp and paper industry. The designs were done for two 1985 market pulp mills: one in New England, and the other in the Northwest. The second set of conceptual designs are being performed for two enhanced oil recovery sites. Two additional site specific conceptual designs are planned.

Cogeneration`s role in the emerging energy markets: A report from the University of Colorado  

Science Conference Proceedings (OSTI)

The utilities required to satisfy the university`s electrical, steam and chilled water needs are generated at the cogeneration facility located in the center of the main campus. The building housing this cogeneration facility was constructed in 1909, at this time it contained a cogeneration facility. The original facility produced 1/100 the capacity of the new facility, yet it was housed in the same area. This existing facility burned coal until April 16, 1932, when the last coal train to pass through the campus on the Colorado and Southern tracks whistled at the campus crossing at 8:45 in the evening. This signaled the end to the cogeneration era at the Boulder campus until September 27, 1992, when once again the university began commercial operation of the new cogeneration facility. Implementation of the Public Utilities Regulatory Policy Act of 1978 (PURPA) encouraged the development of cogeneration facilities due to their inherent energy efficiency. The federal government encouraged the development of cogeneration facilities by removing several major obstacles that historically deterred its full development. It was because of this act, coupled with the fact that the university is interested in energy conservation, reliable energy supply, has a large utility load and wishes to save money that they proceeded with their project. The paper describes the cogeneration system process and power options.

The Role of Feasibility Analysis in Successful Cogeneration  

E-Print Network (OSTI)

Although the energy crisis has given new impetus to cogeneration, many of the considerations that led to its decline during the 20th century still remain. The long hiatus of cogeneration, its reintroduction in new forms, and the emergence of new market considerations leave potential designers and owners unaware of the variety of problems that can cause failure of cogeneration systems or reduce their profitability. Studies of operating and failed cogeneration plants show that feasibility analyses of potential cogeneration installations have been inadequate, resulting in a high failure rate for systems installed in recent decades. Generalizations are drawn from these case studies about the factors that most commonly contribute to success and to failure of cogeneration. Fortunately, certain critical factors favor the application of cogeneration in the industrial sector. The cogeneration feasibility analysis methodology developed by the author is described.

Where is the Cogeneration Business Going?  

E-Print Network (OSTI)

Cogeneration proponents are still haling the wonders and marvels of cogeneration in the hope of convincing customers to adopt this energy option. Despite the hype, fewer and fewer cogeneration projects are being adopted. Why? Where is the business going? Is the bloom off the rose? The answer may be all too obvious. Historically (three to eight years ago), cogeneration was pursued largely because of inadequate or, in some way, failing boilers at industrial plants. These steam generators would have to be replaced or upsized anyway and customers used the combination of capital offsets and low operating efficiencies to justify cogeneration. In cases where these industrial firms did not want anything but the end result (i.e., added steam capacity at some reasonable price) they signed up with energy deal makers who sold them steam at some discount from current costs. Where regulatory agencies forced electric utilities to buy power at levelized or in inflated avoided costs, free steam deals were offered to secure an appropriate steam host. But times have changed. Why are customers interested in cogeneration now? Boiler and chiller-related inadequacies are still present, but power quality has risen to the number one driver (outside of regulatory or electric utility incentives). That may seem somewhat of a surprise since electric utilities are historically more reliable than cogenerators. The best cogeneration systems in the United States achieve 98% availabilities. There isn't a major electric utility that delivers less than 99.9+%. Why the interest? The first reason is momentaries. Many electric utilities do not even keep track of their service disruptions shorter than one minute in duration. Reclosers and other system operations that produce multiple cycle interruptions do not effect annual percent availability, but they sure do effect customers! The reason why is also obvious: microprocessors. Customers are increasing their use of computers in process control and office automation. This combination makes customer productivity and performance extremely power sensitive. Banks and insurance carriers are similarly affected. With the power availability scare so prevalent in the Northeast, and the threat of voltage reductions and interruptions, it is small wonder more customers aren't cogenerating. Part of the reason as well is that thermal efficiency, the very backbone of the reason cogeneration was spawned in 1978, is currently almost a dead issue. PURPA compliance is virtually a non-issue. Customers are even dropping in simple emergency generators and foregoing the heat recovery altogether! How can they make this judgement? Simple! The lure of the current low gas prices has lulled them into benign neglect of the intrinsic cogeneration power generation efficiency. They simply cannot justify heat recovery in the cogeneration system design! Isn't that ironic given the rebirth of cogeneration in 1978 to reduce our dependence on foreign oil by taking advantage of this intrinsic power generation efficiency.

Cogeneration: back on the front burner  

SciTech Connect

State-of-the-art technology for cogeneration includes: Process steam supplied by back pressure of extraction steam-turbine generators; Gas turbines and waste-heat boilers; Diesel engines and waste-heat boilers. In addition, there are a variety of combinations and permutations of state-of-the-art technology such as combined cycles exemplified by gas turbines combined with steam cycles, ''tri-generation'' involving diesel engines to supply shaft power, jacket engines to supply shaft power, jacket cooling water for process heating use, and hot exhaust gases for space heating or to generate steam in waste-heat boilers. Energy savings attributable to cogeneration have averaged 15-20%. Typical investments required for coal-fired steam-turbine cogeneration facilities are on the order of $25 million for a facility consuming 250 million Btu/hour and some analysts see cogeneration supplying 30% of industrial power by the mid-80's. A tabulation summarizes energy savings if cogeneration were implemented in selected plants in the food, textile, pulp and paper, chemical, andnd petroleum refining sectors of industry.

Cogeneration: An Industrial Steam and Power Option  

E-Print Network (OSTI)

Industrial facilities of all sizes have the ability to reduce and better control both power and steam costs with a cogeneration system. Unlike the larger systems that sell almost all of the cogenerated power to a regulated electric utility, these internal use systems use the cogenerated power on-site to reduce power purchases. Ranging from a few hundred kilowatts to tens of megawatts, they are somewhat smaller than the Wholesale Power systems; system size is determined by the industrial plant's electric and thermal requirements and not by an external need for power by a utility. These systems can be very cost effective but require considerably more engineering analysis of site conditions than is typical for a Wholesale Power Project; it is necessary to analyze the industrial host's power and thermal requirements on an hour by hour basis. Moreover, because economic viability is dependent upon displacing some or all of the industrial site's purchased power requirements, considerable attention must be given to the analysis of the local utility's retail rates. This paper describes the concept of an Internal Use cogeneration system and reviews some of the key factors that must be considered in evaluating the viability of a cogeneration facility at any specific industrial site.

Role of fuel cells in industrial cogeneration  

SciTech Connect

During the early years (1958 to 1963), three types of fuel cells were under development: phosphoric acid (PAFC), molten carbonate (MCFC), and solid oxide (SOFC) fuel cells. Between 1963 and 1971, the IGT research and development effort concentrated on the phosphoric acid and molten carbonate technologies; since 1971, emphasis has been on the molten carbonate fuel cell. IGT believes MCFC is best suited to meet the goals of the electric industry and the requirements of industrial cogeneration. Through the years, IGT has conducted system studies to evaluate the role that each one of the three fuel cell types can play in industrial cogeneration. This paper briefly discusses the status of the three technologies, the potential industrial cogeneration market, the application of fuel cells to this market, and the potential fuel savings for several industrial categories.

Evaluating Sites for Industrial Cogeneration in Chicago  

E-Print Network (OSTI)

Cogeneration is an industrial energy conservation technology that is particularly suited to urban applications. Large cities and metropolitan areas have large numbers of energy intensive industrial firms as well as commercial buildings; universities and hospital complexes; and new, densely populated residential developments that have large thermal and electric demands. Potential sites have been evaluated as part of a project to encourage industrial cogeneration applications in Chicago. Energy-intensive industries and commercial, industrial, and residential facilities were grouped by energy use type. Natural gas and electricity consumption data then were used to develop energy use profiles by energy use type and location. Complementary thermal energy use profiles and the geographical proximity of firms and facilities were used to exclude unfavorable sites. Thirty-four sites were then evaluated in detail and ranked according to their suitability for consideration in detailed feasibility studies of different cogeneration technologies.

Extra cogeneration step seen boosting output 20%  

SciTech Connect

Cogenerators can now buy a prototype 6.5 MW, pre-packaged cogeneration system that incorporates an added step to its cycle to reduce fuel use by 21%. Larger, custom-designed systems will be on the market in 1985. Fayette Manufacturing Co. will offer the Kalina Cycle system at a discount price of $8.2 million (1200/kW) until the systems are competitive with conventional units. The system varies from conventional cogeneration systems by adding a distillation step, which permits the use of two fluids for the turbine steam and operates at a higher thermodynamic efficiency, with boiling occuring at high temperature and low pressure. Although theoretically correct, DOE will withhold judgment on the system's efficiency until the first installation is operating.

Coal-Fired Fluidized Bed Combustion Cogeneration  

E-Print Network (OSTI)

The availability of an environmentally acceptable multifuel technology, such as fluidized bed combustion, has encouraged many steam producers/ users to investigate switching from oil or gas to coal. Changes in federal regulations encouraging cogeneration have further enhanced the economic incentives for primary fuel switching. However, this addition of cogeneration to the fuel conversion analysis considerably complicates the investigation. A system design for cogeneration of steam and electricity at a nominal 40,000 pound per hour capacity utilizing fluidized bed combustion is described. The basic system incorporates silo storage of coal, ash, and limestone with dense phase conveying. The system generates power utilizing either a backpressure turbine or a condensing turbine with steam extraction. Three case studies performed for specific end users are presented. The interaction among plant steam requirements, rate purchase structure, and electrical energy buy back rate is discussed. How these factors interact determine the final design and the choice of fuels is illustrated. Because the decision to switch fuel, as well as to cogenerate, is usually economically motivated, an in-depth understanding of the steam/electrical needs and interactions is critical. How these considerations are integrated in the system and the effect they have on the monetary returns are discussed. Electric rate agreements vary significantly from one state to another. Therefore, the examples selected are intended to provide, insight into this variability. For example, one rate structure encourages solid fuel cogeneration. The second is a block structure with low sell back rates making cogeneration difficult to justify. How these rate schedules affected the recommended design illustrates that the system selection is very important.

Cogeneration: Where will it fit in the deregulated market?  

SciTech Connect

Cogeneration due to potentially high efficiency can be very competitive in a deregulated market. Cogeneration can achieve extremely high levels of thermal efficiency, much higher than the most advanced and sophisticated combined cycle power plants generating only electric power. Thermal efficiency is one of the key factors in determining the power plant economics and feasibility. High efficiency means a lesser amount of fuel is used to generate the same amount of energy. In turn, burning a lesser amount of fuel means that fewer pollutants will be emitted. The paper first describes cogeneration plants, then discusses the importance of thermal load availability, cogeneration and distributed generation and other issues affecting cogeneration.

Cogeneration: The Need for Utility-Industry Cooperation  

E-Print Network (OSTI)

Cogeneration is receiving increasing attention because of its potential for efficient utilization of energy. Many recent cogeneration studies, however, have concentrated on the benefits and costs of cogeneration to industry, giving little consideration to utility roles and perspectives. This paper provides an overview of a project sponsored by the Electric Power Research Institute to evaluate industrial cogeneration applications, taking into account utility interactions and impacts. Recent changes in federal legislation, particularly the enactment of the Public Utility Regulatory Policies Act (PURPA), have attempted to remove many of the institutional barriers which in the past made industry hesitant to invest in cogeneration. However, to implement the most attractive cogeneration systems industry must consider the changing economics of utility power generation. Also, despite the attractiveness of cogeneration, many industrial managers are reluctant to invest scarce capital in an area which they do not consider a natural extension of their business. At the same time, many utilities facing slower load growth and economic/environmental /institutional constraints on capacity expansion are willing to consider cogeneration as an option. Cogeneration projects can be highly complementary to the traditional utility business and possibly offer an attractive profit potential. Also, utilities can offer industry the needed expertise to implement and operate cogeneration systems. Considerable benefits may therefore be derived from cooperative cogeneration ventures among utilities and industrial firms. Many different organizational and financial arrangements can be structured, including third party financing. The, paper will briefly discuss the need for and benefits of cooperative efforts and provide illustrative examples of different institutional arrangements.

Lithium in LP 944-20  

E-Print Network (OSTI)

We present a new estimate of the lithium abundance in the atmosphere of the brown dwarf LP 944-20. Our analysis is based on a self-consistent analysis of low, intermediate and high resolution optical and near-infrared spectra. We obtain log N(Li) = 3.25 +/-0.25 using fits of our synthetic spectra to the Li I resonance line doublet profiles observed with VLT/UVES and AAT/SPIRAL. This lithium abundance is over two orders of magnitude larger than previous estimates in the literature. In order to obtain good fits of the resonance lines of K I and Rb I and better fits to the TiO molecular absorption around the Li I resonance line, we invoke a semi-empirical model atmosphere with the dusty clouds located above the photosphere. The lithium abundance, however, is not changed by the effects of the dusty clouds. We discuss the implications of our estimate of the lithium abundance in LP 944-20 for the understanding of the properties of this benchmark brown dwarf.

Thermal tracking cogeneration -- A new or old idea? Cogeneration for multi-thermal loads  

SciTech Connect

The idea of designing a cogeneration project that produces electricity based on the existing heating load is common to many cogeneration projects, but may be limiting the ultimate potential to the end user. Cogeneration which is developed as a power generator producing a small amount of steam for a host load is also common. However, the idea of designing a cogeneration facility to track multiple utility loads is not as common. Where the concept has been used, the projects have been very successful. This article has been written as a primer for professionals looking for ideas when performing analysis of a potential cogeneration project, and as a thought-provoker for end users. The authors will look at each of the possible loads, outline various technical considerations and factors, look at the factors impacting the economics, and lay out an approach that would provide assistance to those trying to analyze a cogeneration project without specialized engineering assistance. Regulatory, legal and financing issues are covered in other sources.

The success of cogeneration in Europe  

SciTech Connect

The European engineers take a different approach to designing cogeneration plants. Instead of building large gas turbines or combined cycle plants whose main target is to produce electricity and then trying to utilize as much heat as possible, European engineers target the replacement of the base heat supply of certain, small scale entities. By focusing on the annual heat demand graph, the basic layout for maximum utilization is determined. If a plant can use all or a majority of the electricity, the by-product, produced in this combined process, the perfect requirements are a given. Today cogeneration is one of the prime technologies available to achieve two valuable goals: efficient usage of limited resources and air pollution reduction. In every major European country there is a non-profit organization promoting the usage of cogeneration and acting as a platform for the various interests involved. These national institutions are members of Cogen Europe, a non-profit organization based in Brussels, Belgium, whose main focus is to promote cogeneration to a multinational level.

Combined Cycle Cogeneration at NALCO Chemical  

E-Print Network (OSTI)

The Nalco Chemical Company, while expanding their corporate headquarters, elected to investigate the potential for cogeneration. The headquarters complex has a central physical plant for heating and chilling. The authors describe the analysis approach for determining the most economical system design. Generation capacity ranging from 2.7 MW up to 7.0 MW in both simple cycle cogeneration and combined cycle cogeneration was analyzed. Both single pressure and dual pressure waste heat boilers were included in the evaluation. In addition, absorption chilling and electrical centrifugal chilling capacity expansion were integrated into the model. The gas turbine selection procedure is outlined. Bid evaluation procedure involved a life cycle cost comparison wherein the bid specification responses for each model turbine were incorporated into the life cycle facility program. The recommendation for the facility is a 4.0MW combined cycle cogeneration system. This system is scheduled for startup in October of 1985. Most major equipment has been purchased and the building to house the system is nearing completion. A discussion of the purchase and scheduling integration will be included.

Heat Recovery Design Considerations for Cogeneration Systems  

E-Print Network (OSTI)

The design and integration of the heat recovery section, which includes the steam generation, auxiliary firing, and steam turbine modules, is critical to the overall performance and economics of cogeneration, systems. In gas turbine topping cogeneration systems, over two-thirds of the energy is in the exhaust gases leaving the gas turbine. In bottoming cycles, where steam and/or electrical power are generated from heating process exhaust streams, the heat recovery design is of primary concern. John Zink Company, since 1929, has specialized in the development, design, and fabrication of energy efficient equipment for the industrial and commercial markets. The paper outlines the design, installation and performance of recently supplied gas turbine cogeneration heat recovery systems.

Quantum L_p and Orlicz spaces  

E-Print Network (OSTI)

Let $\\A$ ($\\cM$) be a $C^*$-algebra (a von Neumann algebra respectively). By a quantum dynamical system we shall understand the pair $({\\A}, T)$ ($({\\cM}, T)$) where $T : {\\A} \\to {\\A}$ ($T : {\\cM} \\to {\\cM}$) is a linear, positive (normal respectively), and identity preserving map. In our lecture, we discuss how the techniques of quantum Orlicz spaces may be used to study quantum dynamical systems. To this end, we firstly give a brief exposition of the theory of quantum dynamical systems in quantum $L_p$ spaces. Secondly, we describe the Banach space approach to quantization of classical Orlicz spaces. We will discuss the necessity of the generalization of $L_p$-space techniques. Some emphasis will be put on the construction of non-commutative Orlicz spaces. The question of lifting dynamical systems defined on von Neumann algebra to a dynamical system defined in terms of quantum Orlicz space will be discussed.

Reference guide to small cogeneration systems for utilities. Final report  

SciTech Connect

This report covers systems performance and cost data for selected smaller cogeneration systems, which are defined generally as those cogeneration systems in the range below 5 megawatts. The data presented in this guide are expected to be used in two main ways. First, the data can be used to extend the existing DEUS Computer Evaluation Model data base to the smaller cogeneration systems. Second, the data will serve as a general guide to smaller cogeneration systems for use by the utilities companies and others. The data pertain to the following cogeneration system: gas turbine with heat recovery boiler, back pressure and extraction/condensing steam turbine, combined cycle, internal combustion (reciprocating) engine, steam bottoming cycle using industrial process exhaust, and gas turbine topping cycle with standard industrial process steam generators. A no-cogeneration base case is included for comparison purposes.

Micro cogeneration: roadblocks to mass markets  

SciTech Connect

The market for micro cogeneration using units of 30 kW or less is in its infancy, and is currently limited to health care, recreation, lodging, and multi-unit residential facilities. There have been some inroads into the restaurant and fast food outlets, light industry, and some supermarkets. A mass market potential will require the industry to produce a module that is as generic as a home air conditioner or heat pump. In order for modular cogenerators to be look upon as appliances, they must be assembled as a package at the factory for easy installation and maintenance. Some utilities can create barriers to interconnections, which would have a negative effect on the market.

Closed cycle cogeneration for the future  

Science Conference Proceedings (OSTI)

While present energy needs can be met with available supplies of fossil fuels, the need to plan for the eventual elimination of dependence on premium fuels in utility and industrial applications remains urgent. One of the most promising power conversion technologies for these needs is the closed cycle gas turbine (CCGT) configured for power and heat production. Closed cycle gas turbines have been in commercial use, principally in Europe, for over four decades. That experience base, combined with emerging awareness of potential CCGT applications, could lead to the operation of coal-fired CCGT cogeneration systems in the U.S. within the next decade. This paper discusses the multi-fuel capability of the CCGT and compares its performance as a flexible cogeneration system with that of a more conventional steam turbine system.

Cogeneration with Thermionics and Electrochemical Cells  

E-Print Network (OSTI)

Thermionic energy converters convert high-temperature heat into high-current low-voltage direct current, rejecting heat at a temperature that is high enough to generate process steam. Electrochemical cells are high-current low-voltage devices, which are ideally suited for coupling to the output of the thermionic converters. A test is under way in which an array of thermionic converters is coupled to a industrial heater. The array will be tested to yield thermionic performance data. These data will be used in the design of a thermionic cogeneration system specifically applied to the chlorine caustic soda industry. A full-scale cogeneration installation of this type is expected to produce about 12 kilowatts of direct current power for each million Btu fired.

An Assessment of Economic Analysis Methods for Cogeneration Systems  

E-Print Network (OSTI)

Cogeneration feasibility studies were conducted for eleven state agencies of Texas. A net present value (NPV) analysis was used to evaluate candidate cogeneration systems and select the optimum system. CELCAP, an hour-by-hour cogeneration analysis computer program was used to determine the costs used in the NPV analysis. The results of the studies showed that the state could save over $6,000,000 per year in reduced utility bills. Different methods of analyzing the economic performance of a cogeneration system are presented for comparison. Other implications of the study are also discussed.

Evaluating Utility Costs from Cogeneration Facilities  

E-Print Network (OSTI)

This paper describes the method of calculation of incremental costs of steam, condensate, feedwater and electricity produced by the industrial cogeneration plant. (This method can also be applied to other energy production plants.) It also shows how to evaluate the energy consumption by the process facility using the costs determined by the method. The paper gives practical examples of calculation of the incremental costs of various utilities and emphasizes the importance of the calculation accuracy.

Cogeneration Markets: An Industry in Transition  

E-Print Network (OSTI)

The year 1986 saw three fundamental changes in the character of development of cogeneration on the U.S. Gulf Coast. First, numerous large projects were cancelled, delayed, or drastically down-sized during 1986. Most capacity reduction or delay was accountable to very large, multiple gas turbine combined cycle systems, including much more electric generating capability than was matched with or needed to serve a useful process steam demand. Second, previously initiated projects designed wholly or largely to supply legitimate thermal demands generally sent forward. Third, there was a threefold increase in wheeling of cogenerated electricity out of HL&P’s service area to the service areas of other utilities. All of these effects are traceable to rapidly declining rates at which HL&P purchases electricity and to increased demand for electricity by some other utilities. These trends imply a future for cogeneration in the HL&P service area characterized by construction of small projects intended to serve plant internal thermal and electrical loads only and/or development of a few relatively large projects for sale to other electric utilities.

An Assessment of Industrial Cogeneration Potential in Pennsylvania  

E-Print Network (OSTI)

This paper summarizes the study, Assessment of Industrial Cogeneration in Pennsylvania, performed by Synergic Resources Corporation for the Pennsylvania Governor's Energy Council. The study could well be the most comprehensive statewide evaluation of industrial cogeneration yet conducted. Although a multitude of estimates of cogeneration potential have surfaced in recent years, this study examined cogeneration opportunities in much greater detail for the following factors: 1. Sales of cogenerated electricity to all major utilities were valued using the estimated PURPA rates based on the Public Utility Commission rules. The demonstrated effects of the wide variation of expected PURPA utility purchase rates on industry-specific economical cogeneration potential further underscores the significance of these rates; 2. Industrial energy consumption (including the use of feedstocks and internally generated fuels) reflected the most accurate data available at both the state and national levels; 3. Pennsylvania-specific forecasts of industrial growth for each major manufacturing industry were incorporated; 4. Forecasts of fuel and electricity price changes were also state-specific rather than national or regional; 5. Discounted cash flow economic analyses were performed for cases in which existing combustion systems both did and did not require replacement as well as for expansions of existing industrial plants and new plants for the years 1985, 1990, and 2000; 6. Emerging technologies such as atmospheric fluidized bed combustion, coal-gasification combined cycles, fuel cells and bottoming cycles were analyzed in addition to the economic assessment of conventional cogeneration systems; Industry-specific rates of market penetration were developed and applied to determine likely levels of market penetration; 7. Sensitivity of cogeneration feasibility with respect to alternative; 8. Ownership and financing arrangements (such as utility and third party ownership) as well as changes in forecasts of PURPA and retail electricity rates, fuel prices, industrial growth rates, and cogeneration technology capital costs and operating characteristics were examined; 9. To more accurately assess the potential for additional cogeneration development, a detailed survey was conducted identifying all existing cogenerators in Pennsylvania; 10. Case study economic analyses were performed for 30 companies to further illustrate cogeneration feasibility; and 11. Barriers to and opportunities for greater industrial cogeneration were identified and a booklet to market cogeneration to industry was developed.

Case Studies of Industrial Cogeneration in the U. S.  

E-Print Network (OSTI)

This paper describes the results of a survey and evaluation of plant-specific information on industrial cogeneration. The study was performed as part of a project sponsored by the Electric Power Research Institute to evaluate Dual Energy Use Systems (DEUS). The purpose of this project was to evaluate site specific data on DEUS from the utility perspective, identify promising candidates, and define R&D opportunities. The first major task in this DEUS project was a survey of industrial cogeneration sites to identify the technoeconomic and institutional factors affecting the success of cogeneration systems in industry. Sites were selected based on a mix of industry types, geographic location, type of cogeneration system, generating capacity, age of plant and other characteristics. Site-specific surveys were conducted and supplemented by information from secondary sources such as FERC and DOE statistical data systems. This paper presents information on 17 cogeneration facilities. Also presented is information on the perspectives of the relevant utilities.

York County Energy Partners CFB Cogeneration Project. Annual report, [September 30, 1992--September 30, 1993  

SciTech Connect

The Department of Energy, under the Clean Coal Technology program, proposes to provide cost-shared financial assistance for the construction of a utility-scale circulating fluidized bed technology cogeneration facility by York County Energy Partners, L.P (YCEP). YCEP, a project company of ir Products and Chemicals, Inc., would design, construct and operate a 250 megawatt (gross) coal-fired cogeneration facility on a 38-acre parcel in North Codorus Township, York County, Pennsylvania. The facility would be located adjacent to the P. H. Glatfelter Company paper mill, the proposed steam host. Electricity would be delivered to Metropolitan Edison Company. The facility would demonstrate new technology designed to greatly increase energy efficiency and reduce air pollutant emissions over current generally available commercial technology which utilizes coal fuel. The facility would include a single train circulating fluidized bed boiler, a pollution control train consisting of limestone injection for reducing emissions of sulfur dioxide by greater than 92 percent, selective non-catalytic reduction for reducing emissions of nitrogen oxides, and a fabric filter (baghouse) for reducing emissions of particulates. Section II of this report provides a general description of the facility. Section III describes the site specifics associated with the facility when it was proposed to be located in West Manchester Township. After the Cooperative Agreement was signed, YCEP decided to move the proposed site to North Codorus Township. The reasons for the move and the site specifics of that site are detailed in Section IV. This section of the report also provides detailed descriptions of several key pieces of equipment. The circulating fluidized bed boiler (CFB), its design scale-up and testing is given particular emphasis.

Presented here are charts that provide a quick look at the relationship among the primary variables that affect the viability of a cogeneration project. The graphs are not intended to be complete feasibility studies, but rather screening aids for understanding the important interrelationships. Use of the charts will enable engineers to compare the predominant system options: gas turbine with heat-recovery steam generator (HRSG), diesel engine with HRSG, and fired boiler with steam turbine. The three options are presented separately because of differing capital costs and heat balances.

High efficiency two-stage absorption chillers of the type used at Rice University Cogen Plant offer the most attractive utilization of recoverable thermal energy. With a coefficient of performance (COP) up to 1.25, the two-stage, parallel flow absorption chiller can offer over fifty (50) percent more useful thermal energy from the same waste heat source--gas turbine exhaust, I.C. engine exhaust and jacketwater, incinerator exhaust, or steam turbine extraction.

The Utilities' Role in Conservation and Cogeneration  

E-Print Network (OSTI)

The electric utility industry is uniquely qualified and positioned to serve as an effective 'deliverer' of energy conservation services and alternative energy supply options, such as cogeneration, rather than merely as a 'facilitator' of their development by other parties. Amendments to current legislation are required to remove the barriers to utility participation and to provide electric utilities with appropriate incentives to deliver conservation and alternative power sources in their own self-interest. That utility self-interest can take the form of benefits to its ratepayers or stockholders -- or, optimally, to both. Moreover, adequate, reliable and economical electric energy from the utility grid is vital to our nation's economic well-being. A financially healthy electric utility industry is essential to the realization of this goal. Therefore, as we continue to refine a national energy policy, we must give this requisite careful attention when developing positions on conservation, cogeneration, equitable rate design, and all of the other elements, for they are inextricably related.

The Dynamics of Cogeneration or "The PURPA Ameoba"  

E-Print Network (OSTI)

PURPA legislatively removed obstacles that had previously served as disincentives to the development of cogeneration. As a result, projects that met certain fuel efficiency standards and other criteria could now theoretically move forward. Because of a number of institutional and technical reasons, the nature of the cogeneration industry has undergone significant changes during its brief life span. Since the passage of PURPA, the entire cogeneration situation on all fronts (the Utility commissions, utilities, and cogenerators) can be characterized as very dynamic. State Utility Commissions are struggling to implement rational policies to deal with the very complex matrix of issues and concerns. Utilities attitudes have changed as they recognize the inevitability of cogeneration and attempt to integrate lit into their system. Cogenerators approach to projects have undergone changes in response to economic realities and the developing policies of the Commissions and the utilities. Past and present trends in the dynamic development of cogeneration are identified in this paper land the reasons for their existence are examined. An understanding of the basic reasons for these trends helps provide insight into where the industry may be headed in the future.

Hotel dual-cogeneration plant saving 33% on electricity costs  

SciTech Connect

Hotel Del Coronado in California has two cogeneration systems in operation, one gas turbine based, the other an advanced solar photovoltaic installation which cuts its electric bill by $400,000 per year. In order to make the new installation as unobstrusive as possible, the gas turbine and waste heat boiler units were placed underground. The sunlight-to-electricity efficiency of the photovoltaic cogeneration system is about 8% and the thermal conversion efficiency about 50%. That makes for an overall 58% cogeneration efficiency. The design uses silicon solar cells specially designed for concentrator application.

Guidelines for Assessing the Feasibility of Small Cogeneration Systems  

E-Print Network (OSTI)

Cogeneration has long been practiced by large industrial firms, which have relatively constant demands for both electricity and heat. In recent years cogeneration has also become attractive for smaller energy users as a result of the great escalation of energy prices in the last decade and the passage of PURPA. Where electric rates are sufficiently high, cogeneration can be feasible for entities having energy bills as low as $500,000 per year, including small industrial firms, office buildings, hospitals, colleges, and shopping centers. This paper will present guidelines for assessing the feasibility of cogeneration for small to medium sized energy users, and it will describe the commercially available technologies that can be utilized.

Urban Integrated Industrial Cogeneration Systems Analysis. Phase II final report  

SciTech Connect

Through the Urban Integrated Industrial Cogeneration Systems Analysis (UIICSA), the City of Chicago embarked upon an ambitious effort to identify the measure the overall industrial cogeneration market in the city and to evaluate in detail the most promising market opportunities. This report discusses the background of the work completed during Phase II of the UIICSA and presents the results of economic feasibility studies conducted for three potential cogeneration sites in Chicago. Phase II focused on the feasibility of cogeneration at the three most promising sites: the Stockyards and Calumet industrial areas, and the Ford City commercial/industrial complex. Each feasibility case study considered the energy load requirements of the existing facilities at the site and the potential for attracting and serving new growth in the area. Alternative fuels and technologies, and ownership and financing options were also incorporated into the case studies. Finally, site specific considerations such as development incentives, zoning and building code restrictions and environmental requirements were investigated.

Advanced Cogeneration Control, Optimization, and Management: A Case Study  

E-Print Network (OSTI)

The performance of cogeneration power plants can now be assessed on line in real time using a distributed microprocessor-based data acquisition and control system. A representative implementation is described for cogeneration power in a food processing plant. The COPA (COgeneration Performance Assessment) package comprises separate, distributed control modules for data input, performance analysis for each plant device, overall plant performance summary, and operator displays. Performance of each of the respective cogeneration devices is assessed relative to a performance model of the device, thus an accurate assessment of performance is provided under all load conditions. Operator displays provide real time depiction of the performance of each device and the overall plant performance. Deterioration of performance of a device is quantified in terms of the cost of additional fuel requirements and/or the value of power not produced.

Role of fuel cells in industrial cogeneration  

Science Conference Proceedings (OSTI)

Work at the Institute of Gas Technology on fuel cell technology for commercial application has focused on phosphoric acid (PAFC), molten carbonate (MCFC), and solid oxide (SOFC) fuel cells. The author describes the status of the three technologies, and concludes that the MCFC in particular can efficiently supply energy in industrial cogeneration applications. The four largest industrial markets are primary metals, chemicals, food, and wood products, which collectively represent a potential market of 1000 to 1500 MEe annual additions. At $700 to $900/kW, fuel cells can successfully compete with other advanced systems. An increase in research and development support would be in the best interest of industry and the nation. 1 reference, 5 figures, 5 tables.

Electrical Cost Reduction Via Steam Turbine Cogeneration  

E-Print Network (OSTI)

Steam turbine cogeneration is a well established technology which is widely used in industry. However, smaller previously unfeasible applications can now be cost effective due to the packaged system approach which has become available in recent years. The availability of this equipment in a packaged system form makes it feasible to replace pressure reducing valves with turbine generator sets in applications with flows as low as 4000 pounds of steam per hour. These systems produce electricity for $0.01 to $.02 per kWh (based on current costs of gas and oil); system cost is between $200 and $800 per kW of capacity. Simple system paybacks between one and three years are common.

Cogeneration Opportunities in Texas State Agencies  

E-Print Network (OSTI)

In 1983, Texas Governor Mark White initiated an energy cost containment program for the largest state agencies. The Energy Management Group of the Mechanical Engineering Department at Texas A&M University was called on to provide technical support in the area of cogeneration. Ten agencies were selected for detailed study. This paper gives some information on the results of the studies performed on the University of Houston and Southwest Texas State University. In both cases, simple payback was conservatively estimated at around four years. When the two systems were sized so that they would not be in a position of selling excess power, their combined savings were estimated at over $2.7 million annually.

This paper presents the development of a quasi-linear optimization model for a cogeneration system subject to constant heat and power demands or loads. The linear model is next modified to a non-linear one to account for economies of scale. The models define the necessary and sufficient conditions for system size optimality. Thus, the underlying methodology constitutes the foundation for a subsequent series of more sophisticated cogeneration design models. Several examples are presented to illustrate the models.

THERMODYNAMICS OF PARTIALLY FROZEN COOLING LAKES  

SciTech Connect

The Rochester Institute of Technology (RIT) collected visible, SWIR, MWIR and LWIR imagery of the Midland (Michigan) Cogeneration Ventures Plant from aircraft during the winter of 2008-2009. RIT also made ground-based measurements of lake water and ice temperatures, ice thickness and atmospheric variables. The Savannah River National Laboratory (SRNL) used the data collected by RIT and a 3-D hydrodynamic code to simulate the Midland cooling lake. The hydrodynamic code was able to reproduce the time distribution of ice coverage on the lake during the entire winter. The simulations and data show that the amount of ice coverage is almost linearly proportional to the rate at which heat is injected into the lake (Q). Very rapid melting of ice occurs when strong winds accelerate the movement of warm water underneath the ice. A snow layer on top of the ice acts as an insulator and decreases the rate of heat loss from the water below the ice to the atmosphere above. The simulated ice cover on the lake was not highly sensitive to the thickness of the snow layer. The simplicity of the relationship between ice cover and Q and the weak responses of ice cover to snow depth over the ice are probably attributable to the negative feedback loop that exists between ice cover and heat loss to the atmosphere.

Evaluation of diurnal thermal energy storage combined with cogeneration systems  

DOE Green Energy (OSTI)

This report describes the results of an evaluation of thermal energy storage (TES) integrated with simple gas turbine cogeneration systems. The TES system captures and stores thermal energy from the gas turbine exhaust for immediate or future generation of process heat. Integrating thermal energy storage with conventional cogeneration equipment increases the initial cost of the combined system; but, by decoupling electric power and process heat production, the system offers the following two significant advantages: (1) Electric power can be generated on demand, irrespective of the process heat load profile, thus increasing the value of the power produced; (2) Although supplementary firing could be used to serve independently varying electric and process heat loads, this approach is inefficient. Integrating TES with cogeneration can serve the two independent loads while firing all fuel in the gas turbine. The study evaluated the cost of power produced by cogeneration and cogeneration/TES systems designed to serve a fixed process steam load. The value of the process steam was set at the levelized cost estimated for the steam from a conventional stand-alone boiler. Power costs for combustion turbine and combined-cycle power plants were also calculated for comparison. The results indicated that peak power production costs for the cogeneration/TES systems were between 25% and 40% lower than peak power costs estimated for a combustion turbine and between 15% and 35% lower than peak power costs estimated for a combined-cycle plant. The ranges reflect differences in the daily power production schedule and process steam pressure/temperature assumptions for the cases evaluated. Further cost reductions may result from optimization of current cogeneration/TES system designs and improvement in TES technology through future research and development.

A Feasibility Study of Fuel Cell Cogeneration in Industry  

E-Print Network (OSTI)

Up until now, most of the literature on fuel cell cogeneration describes cogeneration at commercial sites. In this study, a PC25C phosphoric acid fuel cell cogeneration system was designed for an industrial facility and an economic analysis was performed. The US DOE Industrial Assessment Center (IAC) database was examined to determine what industry considers a good investment for energy saving measures. Finally, the results of the cogeneration analysis and database investigation were used to project the conditions in which the PC25C might be accepted by industry. Analysis of IAC database revealed that energy conservation recommendations with simple paybacks as high as five years have a 40% implementation rate; however, using current prices the simple payback of the PC25C fuel cell exceeds the likely lifetime of the machine. One drawback of the PC25C for industrial cogeneration is that the temperature of heat delivered is not sufficient to produce steam, which severely limits its usefulness in many industrial settings. The cost effectiveness of the system is highly dependent on energy prices. A five year simple payback can be achieved if the cost of electricity is $0.10/kWh or greater, or if the cost of the fuel cell decreases from about $3,500/kW to $950/kW. On the other hand, increasing prices of natural gas make the PC25C less economically attractive.

Alternatives to Industrial Cogeneration: A Pinch Technology Perspective  

E-Print Network (OSTI)

Pinch Technology studies across a broad spectrum of processes confirm that existing plants typically consume 15-40% more thermal energy than they should. Consequently, many cogeneration schemes have been based on thermal requirements and characteristics that are inconsistent with a properly designed and integrated process. Pinch Technology studies also frequently identify projects, based on conventional technology, that require lower capital outlays, achieve more rapid paybacks, and entail less risk than those associated with proposed cogeneration projects. Cogeneration schemes that survive the scrutiny of Pinch Technology are often smaller -- but invariably more cost-effective -- than those being contemplated or now being operated. Most importantly, only the results of such a study truly enable the process operator to evaluate the relative merits of cogeneration and other options for reducing operating costs. Recognizing that cogeneration will, at times, be an appropriate part of an industrial process, utilities have an opportunity to work with their industrial customers using Pinch Technology to insure that the alternatives are properly defined and well understood. Recent case study results show that such cooperation can often yield sounder capital investment decisions and lower operating costs for the industrial operator and load-building and load-retention opportunities for the utility.

Efficiently generate steam from cogeneration plants  

SciTech Connect

As cogeneration gets more popular, some plants have two choices of equipment for generating steam. Plant engineers need to have a decision chart to split the duty efficiently between (oil-fired or gas-fired) steam generators (SGs) and heat recovery steam generators (HRSGs) using the exhaust from gas turbines. Underlying the dilemma is that the load-versus-efficiency characteristics of both types of equipment are different. When the limitations of each type of equipment and its capability are considered, analysis can come up with several selection possibilities. It is almost always more efficient to generate steam in an HRSG (designed for firing) as compared with conventional steam generators. However, other aspects, such as maintenance, availability of personnel, equipment limitations and operating costs, should also be considered before making a final decision. Loading each type of equipment differently also affects the overall efficiency or the fuel consumption. This article describes the performance aspects of representative steam generators and gas turbine HRSGs and suggests how plant engineers can generate steam efficiently. It also illustrates how to construct a decision chart for a typical installation. The equipment was picked arbitrarily to show the method. The natural gas fired steam generator has a maximum capacity of 100,000 lb/h, 400-psig saturated steam, and the gas-turbine-exhaust HRSG has the same capacity. It is designed for supplementary firing with natural gas.

Application of Cogeneration to Small Commercial Systems  

E-Print Network (OSTI)

Co-generation is sometimes defined as a customer owned, electrical generating system capable of feeding power back into the Electric Utility lines for compensation. For a long time, the Electric Utility Companies took the position that a customer could use electrical generating equipment for 'Emergency Standby', but only when the Utility power was not available. After all, the power company was in the business of selling power, and didn't want to have its customers in competition with them, whenever they wanted to generate their own power. With the Energy shortage of 1973 and subsequent events, where increased demands for more power were being made upon the Utilities, coupled with complex restrictions being placed upon the construction of new power plants, the utilities found that they needed all the help they could get to meet their peak demands. Recent Supreme Court rulings have now mandated that Utility companies must accept customer generated power, whenever the customer has excess generating capacity, and he should be compensated for same at reasonable rates.

The Influence of Regulation on the Decision to Cogenerate  

E-Print Network (OSTI)

This paper will be primarily on the Public Utility Commission of Texas' Substantive Rules that explicitly address cogeneration (Section 23.66). The original rules, which were implemented following the mandate of the Texas legislature, have undergone substantial change. More specifically, rules have been structured to promote a market for capacity without harming existing and future ratepayers. Discussion will focus on how the existing rules can directly influence the decision to cogenerate. Part One provides a brief history of the Section 23.66 rules. Part Two discusses the pricing methodology adopted by the Commission for "firm" and "as-available" power supplied to a utility. Part Three presents a brief discussion of the wheeling rule that was recently adopted by the Commission. Part Four discusses the importance of standby rates on the decision to cogenerate. A discussion of the problems that may arise from traditional cost allocation methodologies for the design of standby rates is also provided.

Analysis of In-Plant Cogeneration Using a Microcomputer  

E-Print Network (OSTI)

The analysis of in-plant cogeneration opportunities requires quantification of several factors. These include, among others, the profiles of plant steam and electricity usage, the temperature and pressure of primary header steam, the dollar value of all energy (steam or electricity) bought, produced, and sold, and turbine/generator operating efficiencies at various loads. Since all of these factors can be quantified, and because a standard procedure can be defined for evaluating in-plant cogeneration opportunities, this task is ideally suited for a digital computer. This paper discusses the development and methodology of a microcomputer program to analyze in-plant cogeneration opportunities. User-oriented features of the program are highlighted and thermodynamic and financial computational routines are discussed. The results obtained by this program for a case study are presented.

High Efficiency Gas Turbines Overcome Cogeneration Project Feasibility Hurdles  

E-Print Network (OSTI)

Cogeneration project feasibility sometimes fails during early planning stages due to an electrical cycle efficiency which could be improved through the use of aeroderivative gas turbine engines. The aeroderivative engine offers greater degrees of freedom in terms of power augmentation through steam injection, NOx control without selective catalytic reduction, (SCR), reduced down time during maintenance and dispatchability. Other factors influencing enhanced aeroderivative economics are complete generator set packaging at the factory and full string testing before the delivery. A wide variety of hosts, including institutions, utilities, municipalities and industrial factories are observing that their cogeneration projects move faster by implementing aeroderivative gas turbine generation packages.

A Philadelphia Ramada Inn recovered the costs of a $150,000 propane-fired cogenerator system within a year. The system reduced the energy consumed for hot water and air conditioning by 35% and reversed the high energy costs the hotel incurred when it was forced to shift from natural gas to electricity. The 170 horsepower system, which handles a variety of liquid and gaseous fuels as well as propane, replaces two boilers that were used to heat water. The hotel supplements cogenerated power with purchases from the utility. Waste heat is recaptured for space and water heating. The system's overall efficiency is 96%.

Petroleum Coke: A Viable Fuel for Cogeneration  

E-Print Network (OSTI)

Petroleum coke is a by-product of the coking process which upgrades (converts) low-valued residual oils into higher-valued transportation, heating and industrial fuels. Pace forecasts that by the year 2000 petroleum coke production will increase from 36 million to 47 million short tons/year. Because the crude pool will continue to become more sour and refiners treat the coker as the "garbage can" the quality of the petroleum cokes will generally degrade- contain higher sulfur and trace metal levels. The U.S. produces nearly 70% of the total and is expected to maintain this share. Domestic markets consumed less than half of the U.S. production; 80% of the high sulfur fuel grade production from the Gulf coast is exported to Japan or Europe. Increasing environmental concerns could disrupt historic markets and threaten coker operations. This would create opportunities for alternate end-uses such as cogeneration projects. The Pace Consultants Inc. continuously monitors and reports on the petroleum coke industry-production and markets-in its multi-client publication The Pace Petroleum Coke Ouarterly. The information presented in this paper is based on this involvement and Pace's experience in single and multi client consulting activities related to the petroleum refining and petroleum coke industries. The purpose is to provide a review of the existing world petroleum coke industry with particular emphasis on the U.S. production and markets. Forecasted production levels and critical factors which could alter the historic market disposition of petroleum coke are addressed.

Economic comparison of cogeneration/combined-cycle alternatives for industry  

SciTech Connect

This paper examines various cogeneration alternatives available today and provides an economic comparison for a range of conditions that will enable the most significant factors to be considered in the selection of cogeneration alternatives, and to determine which alternatives are most suitable for the particular application. The cogeneration methods considered are: a combustion turbine electric generating unit followed by an unfired heat recovery steam generator, a combustion turbine electric generating unit followed by a supplementary fired heat recovery steam generator, a combustion turbine electric generating unit followed by a fully fired boiler, a combined-cycle combustion turbine electric generating unit followed by a supplementary fired high-pressure heat recovery boiler delivering steam to a noncondensing steam turbine-generator, a combined-cycle combustion turbine electric generating unit followed by a fully fired boiler delivering steam to a noncondensing steam turbine-generator, and a conventional coal-fired boiler and a noncondensing steam turbine-generator. It is concluded that over a wide range of financial and operating conditions, almost all of the cogeneration/combined-cycle alternatives are more economical than continued operation of an existing conventional boiler generating steam only.

Fundamentals of a Third-Party Cogeneration Project  

E-Print Network (OSTI)

There is an increasing number of 2-10 MW cogeneration projects involving retrofits at institutional and industrial installations. This type of project requires that the cogeneration equipment be (a) designed and sized to match the electrical and thermal usage of the facility and (b) retrofitted or integrated physically with the facility. Third-party ownership and operation of these installations offer significant advantages such as no capital investment and no risk by the user, technical expertise to handle the more involved implementation of retrofit projects, and the ability to combine cogeneration with other energy conservation measures to reduce total energy costs for many facilities by 15-30%. This paper describes certain fundamentals required for the successful implementation of a third-party cogeneration project such as the 2.5 MW installation at York Hospital in York, Pennsylvania. The most significant fundamentals are the contract between the user and the third party, early contact with the electric utility and gas distribution companies, the ability to keep the capital cost low, the selection of a contractor with retrofit experience, the capability to obtain fuel at favorable terms and conditions, and a practical approach toward operation and maintenance.

Innovative hybrid gas/electric chiller cogeneration  

SciTech Connect

January Progress--A kick-off meeting was held in San Diego with Alturdyne on January 21st. The proposed hybrid gas/electric chiller/cogenerator design concept was discussed in detail. The requirements and functionality of the key component, a variable speed, constant frequency motor/generator was presented. Variations of the proposed design were also discussed based on their technical feasibility, cost and market potential. The discussion is documented in a Trip Report. February Progress--After significant GRI/Alturdyne discussion regarding alternative product design concepts, the team made a decision to continue with the proposed product design, a hybrid chiller capable of also providing emergency power. The primary benefits are: (a) the flexibility and operating cost savings associated with the product's dual fuel capability and (b) the emergency power feature. A variable speed, constant frequency motor/generator would significantly increase the cost of the product while providing marginal benefit. (The variable speed, constant frequency motor generator is estimated to cost $25,000 versus $4,000 for a constant speed version). In addition, the interconnection requirements to the electric grid would significantly limit market penetration of the product. We will proceed with a motor/generator design capable of serving as the electric prime mover for the compressor as well as the generator for emergency power needs. This component design is being discussed with two motor manufacturers. The first generation motor/generator will not be a variable speed, constant frequency design. The variable speed, constant frequency capability can be an advancement that is included at a later time. The induction motor/synchronous generator starts as a wound rotor motor with a brushless exciter and control electronics to switch between induction mode and synchronous mode. The exciter is a three-phase exciter with three phase rotating diode assembly. In the induction motor mode, the field windings are shorted out by SCRs located across the field. In the synchronous mode, a small ct on one of the exciter leads would power the rotating exciter electronics. Upon sensing exciter current, the electronics would automatically open the SCRs allowing synchronous operation. Quotes will be obtained from American Motor and Reuland, two motor/generator vendors. March Progress--A product layout was completed. The width is reduced significantly from the original hybrid design because the evaporator and condenser tube in shell heat exchangers are located below the engine/motor/compressor drive-line. Alturdyne is searching for a consultant to perform a drive-line torsional analysis. This analysis is necessary to ensure that the drive-line is not subject to undue vibrations operating through its entire speed range. Much effort was directed toward motor/generator selection. A decision was made to use Reuland Electric. A motor with double-end shafts will be purchased. The design effort which will be completed at Alturdyne will involve the modification of the wound rotor motor to also provide synchronous power. Work has been completed on developing the new controller which will be utilized for the original hybrid product as well as this advanced product. Work continues toward developing a manufacturing cost estimate. A detailed bill of material will be developed for the product. Key components include the engine, compressor and motor/generator.

Metallurgical evaluation of a failed LP turbine disc. Final report  

SciTech Connect

A metallurgical evaluation of a burst disc from the LP turbine at the Yankee Rowe nuclear generating station was performed. The turbine failure incident involves catastrophic rupture of both No. 1 discs during a start-up. The objectives of the evaluation were to characterize the disc materials and identify the cacking mechanism and other metallurgical factors involved in the failure. Metallographic and fractographic examinations of one segment of the No. generator-end disc were performed. The mechanical properties and composition of the disc segment were also determined. The investigation established that the radial fracture in the disc segment initiated at a service-induced crack and was of a generally brittle character. Also, numerous subcritical cracks were observed in the bore surface.

Cogeneration Waste Heat Recovery at a Coke Calcining Facility  

E-Print Network (OSTI)

PSE Inc. recently completed the design, construction and start-up of a cogeneration plant in which waste heat in the high temperature flue gases of three existing coke calcining kilns is recovered to produce process steam and electrical energy. The heat previously exhausted to the atmosphere is now converted to steam by waste heat recovery boilers. Eighty percent of the steam produced is metered for sale to a major oil refinery, while the remainder passes through a steam turbine generator and is used for deaeration and feedwater heating. The electricity produced is used for the plant auxiliaries and sold to the local utility. Many design concepts were incorporated into the plant which provided for high plant availability, reliability and energy efficiency. This paper will show how these concepts were implemented and incorporated into the detailed design of the plant while making cogeneration a cost effective way to save conventional fuels. Operating data since plant start-up will also be presented.

Small-scale biomass fueled cogeneration systems - A guidebook for general audiences  

Science Conference Proceedings (OSTI)

What is cogeneration and how does it reduce costs? Cogeneration is the production of power -- and useful heat -- from the same fuel. In a typical biomass-fueled cogeneration plant, a steam turbine drives a generator, producing electricity. The plant uses steam from the turbine for heating, drying, or other uses. The benefits of cogeneration can mostly easily be seen through actual samples. For example, cogeneration fits well with the operation of sawmills. Sawmills can produce more steam from their waste wood than they need for drying lumber. Wood waste is a disposal problem unless the sawmill converts it to energy. The case studies in Section 8 illustrate some pluses and minuses of cogeneration. The electricity from the cogeneration plant can do more than meet the in-house requirements of the mill or manufacturing plant. PURPA -- the Public Utilities Regulatory Policies Act of 1978 -- allows a cogenerator to sell power to a utility and make money on the excess power it produces. It requires the utility to buy the power at a fair price -- the utility`s {open_quotes}avoided cost.{close_quotes} This can help make operation of a cogeneration plant practical.

Assessment of cogeneration technologies for use at Department of Defense installations. Final report  

Science Conference Proceedings (OSTI)

Cogeneration is the simultaneous generation of two types of energy, usually electricity and thermal energy, from a single energy source such as natural gas or diesel fuel. Cogeneration systems can be twice (or more) as efficient than conventional energy systems since both the electricity and the available thermal energy produced as a by-product of the electric generation, are used. This study identified cogeneration technologies and equipment capable of meeting Department of Defense (DOD) requirements for generation of electrical and thermal energy and described a wide range of successful cogeneration system configurations potentially applicable to DOD energy plants, including: cogeneration system prime movers, electrical generating equipment, heat recovery equipment, and control systems. State of the art cogeneration components are discussed in detail along with typical applications and analysis tools that are currently available to assist in the evaluation of potential cogeneration projects. A basic analysis was performed for 55 DOD installations to determine the economic benefits of cogeneration to the DOD. The study concludes that, in general, cogeneration systems can be a very cost effective method of providing the military with its energy needs.

Lake Ecology Lake Ecology Name: Jody Location: N/A Country: N/A Date: N/A Question: We have a partically natural/ partially man-dug lake in our back yard. It is approximately 3 acres in size. The fish in this tiny like are plentiful and HUGE :) Bass up to 20" s (so far) and blue gill up to 10"s (so far). My question is this... we appear to have a heavy goose population and I was wondering if they are the cause of the green slimmy stuff that is all over the top of the water as well as the lighter green slime on the plants growing under the water? Are the fish being harmed by waste from the geese and if so, what can I put in the water to ensure their health? Additionally, I noticed hundreds of frogs during the mating period yet I've yet to see even one tad pole and I am at the lake atleast 5 out of the 7 days in a week. Is there a reason for this. The frogs are two toned.. light green with patches of darker shades of green on the head and body. I've never seen frogs like these before but then again, I've never lived in wet lands prior. The frogs are also very agressive... tend to attack fishing line and even leap up to 4' in the air to attack a fishing rod. Thank heavens they don't have teeth! . We do not keep the fish we catch, we always release.

Cogeneration Partnerships -- A "Win-Win" Approach for All Parties  

E-Print Network (OSTI)

"Historically, electric utilities in the US have tended to discourage the deployment of cogeneration installations in their own service territory because the resulting electricity sales reduction would be greater than normal load growth, and thus there would be a negative impact on earnings. For an island-based utility such as Jamaica Public Service Company (JPSCo) that is experiencing strong load growth, however, the situation is quite different. • There is a need to provide new electrical resources on a continuing basis. • There is a need to support the manufacturing sector, to help to grow the economy. • There are no indigenous fuels; expensive imported fuel oil is virtually the only energy source available. Cogeneration is recognized as a proven technology that provides an economical, efficient, and environmental friendly way to increase electricity supply in appropriately sized increments. By facilitating, cogeneration installations and sharing in their ownership, the utility can protect-and under some circumstances even increase its overall revenue stream. The basic concept is as follows: a JPSCo-owned Cogeneration Plant will supply: (1) electricity to the JPSCo grid, and (2) ""energy products"" (such as chilled water, steam, or hot water, and perhaps compressed air) to manufacturing businesses operating within a specific geographic area. Some non-manufacturing facilities in the same area may also be served. The ""energy products"" would be supplied via a local District Energy piping network. The large manufacturing entities who are customers for one of more of the ""energy products"" would be billed for electricity supplied by JPSCo under an new Industrial Park Tariff that is about 10-15% lower than the standard tariff. Ideally, the price charged for each of the ""energy products"" would be competitive with each customer's total cost to produce the same product on-site, or as a minimum each customer's total annual cost for electricity and fuel would be lower. The results of a feasibility study of the concept using data for a specific Industrial Park will be presented in this paper. The rated net electrical capacity of the cogeneration plant is 15 MW (four 4 MW medium-speed diesel engines serve as prime movers.) A total of eight industrial plants are served with electricity, chilled water, and steam. "

Advanced high performance steam systems for industrial cogeneration: Final report  

SciTech Connect

Advanced steam conditions of 1500/sup 0/F and 1500 psig have been shown to offer a major positive economic impact and a dramatic improvement in cogeneration system performance. In a back pressure steam turbine system, electricity production increases by 80%, and the return on investment improves by 60%. For a 35% extraction turbine, the electricity production increases 28% and the return increases by 34%. Designs of a 1500/sup 0/F modular steam generator and two sizes of matching steam turbines have been completed. The steam generator module uses all Alloy 800 tubes except for two superheater rows of Inconel 617. Its design is based on current production Alloy 800 once-through steam generators currently being introduced into cogeneration combined cycles. A test loop is currently evaluating candidate steam generator tube materials and steam turbine materials at 1500/sup 0/F and 1500 psig. To date, 4000 hours of operation of this loop have been accumulated. The candidate metals after operation in 1500/sup 0/F and 1500 psig steam showed no surface distress. Trade-off studies have been completed on the high temperature steam turbine. Tangential, radial, and axial turbine configurations have been designed and evaluated. The stress analyses of the 1500/sup 0/F steam turbines show that the machine can be operated at 1500/sup 0/F and 1500 psig for over ten years without component replacement when using rotor hub cooling to maintain disk bore temperatures in the 900/sup 0/F range. When applied in back pressure steam, extraction steam, and combined cycle systems the ''1500/sup 0/F steam technology building blocks'' provide full coverage of industrial cogeneration from 4 MW to 25 MW in a single gas turbine and steam turbine installation. A twelve-inch diameter tangential flow turbine has also been designed which is optimum in the 1 to 3 MW power range.

Reliability, Availability and Maintainability Considerations for Gas Turbine Cogeneration Systems  

E-Print Network (OSTI)

The success of a cogeneration system depends upon the system being available, i.e. operating and meeting its demands under expected environmental conditions. A high availability in turn, depends on both Reliability (indicating how often the system fails), and Maintainability (indicating how fast it can be returned to a satisfactory operating state). A low availability will adversely effect important economic criteria for the project such as Discounted Cash Flow and Payback. This paper provides a structure by which these important parameters can be addressed at the design evaluation stage. The paper discusses reliability methods and practical aspects such as installation and operation considerations, including air filtration, fuel conditioning and compressor washing.

As in a car heater, internal combustion engines would recover heat from the radiators to heat the house. The IC, inlet and outlet lines, thermostat, muffler (''critical''), induction generator, and reverse power delay are schematicized. Synchronous generators are not recommended. Disadvantages include the potential pollution, high capital cost, and the resistance of homeowners ''acquainted with the problems of owning a car.'' A simple method to determine the economics of home cogeneration is given. Special consideration is paid to the induction generator, and the engine starter.

DOE Green Energy (OSTI)

The Pacific Northwest Laboratory (PNL) leads the U.S. Department of Energy`s Thermal Energy Storage (TES) Program. The program focuses on developing TES for daily cycling (diurnal storage), annual cycling (seasonal storage), and utility-scale applications [utility thermal energy storage (UTES)]. Several of these storage technologies can be used in a new or an existing power generation facility to increase its efficiency and promote the use of the TES technology within the utility and the industrial sectors. The UTES project has included a study of both heat storage and cool storage systems for different utility-scale applications. The study reported here has shown that an oil/rock diurnal TES system, when integrated with a simple gas turbine cogeneration system, can produce on-peak power for $0.045 to $0.06 /kWh, while supplying a 24-hour process steam load. The molten salt storage system was found to be less suitable for simple as well as combined-cycle cogeneration applications. However, certain advanced TES concepts and storage media could substantially improve the performance and economic benefits. In related study of a chill TES system was evaluated for precooling gas turbine inlet air, which showed that an ice storage system could be used to effectively increase the peak generating capacity of gas turbines when operating in hot ambient conditions.

Victorias energy efficiency and cogeneration project. Final report  

DOE Green Energy (OSTI)

This report describes a two-phase energy project currently contemplated for joint implementation at the Victorias Milling Company, a large sugar mill and refinery on the island of Negros in the Visayas region of the Philippines. The Energy Efficiency (EE) phase is expected to reduce of eliminate VMC`s fossil fuel consumption, which will have a direct and substantial impact on carbon emissions. Phase I is an EE project which involves the installation of equipment to reduce steam and electricity demand in the factories. Phase II, will involve retrofitting and increasing the capacity of the steam and power generation systems, and selling power to the grid. By increasing efficiency and output, the cogeneration project will allow the factory to use only bagasse sugar cane fiber waste as fuel for energy needs. The cogeneration project will also eliminate VMC`s electricity purchases and supply additional power for the island, which will offset generation capacity expansion on the island and the Visayas region.

Performance and operational economics estimates for a coal gasification combined-cycle cogeneration powerplant  

SciTech Connect

A performance and operational economics analysis is presented for an integrated-gasifier, combined-cycle (IGCC) system to meet the steam and baseload electrical requirements. The effect of time variations in steam and electrial requirements is included. The amount and timing of electricity purchases from sales to the electric utility are determined. The resulting expenses for purchased electricity and revenues from electricity sales are estimated by using an assumed utility rate structure model. Cogeneration results for a range of potential IGCC cogeneration system sizes are compared with the fuel consumption and costs of natural gas and electricity to meet requirements without cogeneration. The results indicate that an IGCC cogeneration system could save about 10 percent of the total fuel energy presently required to supply steam and electrical requirements without cogeneration. Also for the assumed future fuel and electricity prices, an annual operating cost savings of 21 percent to 26 percent could be achieved with such a cogeneration system. An analysis of the effects of electricity price, fuel price, and system availability indicates that the IGCC cogeneration system has a good potential for economical operation over a wide range in these assumptions.

BP Cherry Point Cogeneration Project, Draft Environmental Impact Statement  

SciTech Connect

BP West Coast Products, LLC (BP or the Applicant) proposes to construct and operate a nominal 720-megawatt (MW), natural-gas-fired, combined-cycle cogeneration facility next to the existing BP Cherry Point Refinery in Whatcom County, Washington. The Applicant also owns and operates the refinery, but the cogeneration facility and the refinery would be operated as separate business units. The cogeneration facility and its ancillary infrastructure would provide steam and 85 MW of electricity to meet the operating needs of the refinery and 635 MW of electrical power for local and regional consumption. The proposed cogeneration facility would be located between Ferndale and Blaine in northwestern Whatcom County, Washington. The Canadian border is approximately 8 miles north of the proposed project site. The Washington State Energy Facility Site Evaluation Council (EFSEC) has jurisdiction over the evaluation of major energy facilities including the proposed project. As such, EFSEC will recommend approval or denial of the proposed cogeneration facility to the governor of Washington after an environmental review. On June 3, 2002, the Applicant filed an Application for Site Certification (ASC No. 2002-01) with EFSEC in accordance with Washington Administrative Code (WAC) 463-42. On April 22, 2003, the Applicant submitted an amended ASC that included, among other things, a change from air to water cooling. With the submission of the ASC and in accordance with the State Environmental Policy Act (SEPA) (WAC 463-47), EFSEC is evaluating the siting of the proposed project and conducting an environmental review with this Environmental Impact Statement (EIS). Because the proposed project requires federal agency approvals and permits, this EIS is intended to meet the requirements under both SEPA and the National Environmental Policy Act (NEPA). The Bonneville Power Administration (Bonneville) and U.S. Army Corps of Engineers (Corps) also will use this EIS as part of their respective decision-making processes associated with the Applicant's request to interconnect to Bonneville's transmission system and proposed location of the project within wetland areas. Therefore, this Draft EIS serves as the environmental review document for SEPA and for NEPA as required by Bonneville for the interconnection and the Corps for its 404 individual permit. The EIS addresses direct, indirect, and cumulative impacts of the proposed project, and potential mitigation measures proposed by the Applicant, as well as measures recommended by EFSEC. The information and resulting analysis presented in this Draft EIS are based primarily on information provided by the Applicant in the ASC No. 2002-01 (BP 2002). Where additional information was used to evaluate the potential impacts associated with the proposed action, that information has been referenced. EFSEC's environmental consultant, Shapiro and Associates, Inc., did not perform additional studies during the preparation of this Draft EIS.

The growth of a C_0-semigroup characterised by its cogenerator  

E-Print Network (OSTI)

We characterise contractivity, boundedness and polynomial boundedness for a C_0-semigroup on a Banach space in terms of its cogenerator V (or the Cayley transform of the generator) or its resolvent. In particular, we extend results of Gomilko and Brenner, Thomee and show that polynomial boundedness of a semigroup implies polynomial boundedness of its cogenerator. As is shown by an example, the result is optimal. For analytic semigroups we show that the converse holds, i.e., polynomial boundedness of the cogenerators implies polynomial boundedness of the semigroup. In addition, we show by simple examples in (C^2,\\|\\cdot\\|_p), p \

Lakes, Lakes, Electricity & You Why It's So Important That Lakes Are Used To Generate Electricity Why We Can Thank Our Lakes For Electricity Because lakes were made to generate electricity. Back in the mid-1940s, Congress recognized the need for better flood control and navigation. To pay for these services, Congress passed laws that started the building of federal hydroelectric dams, and sold the power from the dams under long-term contracts. Today these dams provide efficient, environmentally safe electricity for our cities and rural areas. And now these beautiful lakes are ours to enjoy. There are now 22 major man-made lakes all across the Southeast built under these federal programs and managed by the U.S. Army Corps of Engineers - lakes that help prevent flooding and harness the renewable power of water to generate electricity. Power produced at these lakes is marketed by the Elberton,

Decentralised optimisation of cogeneration in virtual power plants  

Science Conference Proceedings (OSTI)

Within several projects we investigated grid structures and management strategies for active grids with high penetration of renewable energy resources and distributed generation (RES and DG). Those ''smart grids'' should be designed and managed by model based methods, which are elaborated within these projects. Cogeneration plants (CHP) can reduce the greenhouse gas emissions by locally producing heat and electricity. The integration of thermal storage devices is suitable to get more flexibility for the cogeneration operation. If several power plants are bound to centrally managed clusters, it is called ''virtual power plant''. To operate smart grids optimally, new optimisation and model reduction techniques are necessary to get rid with the complexity. There is a great potential for the optimised management of CHPs, which is not yet used. Due to the fact that electrical and thermal demands do not occur simultaneously, a thermally driven CHP cannot supply electrical peak loads when needed. With the usage of thermal storage systems it is possible to decouple electric and thermal production. We developed an optimisation method based on mixed integer linear programming (MILP) for the management of local heat supply systems with CHPs, heating boilers and thermal storages. The algorithm allows the production of thermal and electric energy with a maximal benefit. In addition to fuel and maintenance costs it is assumed that the produced electricity of the CHP is sold at dynamic prices. This developed optimisation algorithm was used for an existing local heat system with 5 CHP units of the same type. An analysis of the potential showed that about 10% increase in benefit is possible compared to a typical thermally driven CHP system under current German boundary conditions. The quality of the optimisation result depends on an accurate prognosis of the thermal load which is realised with an empiric formula fitted with measured data by a multiple regression method. The key functionality of a virtual power plant is to increase the value of the produced power by clustering different plants. The first step of the optimisation concerns the local operation of the individual power generator, the second step is to calculate the contribution to the virtual power plant. With small extensions the suggested MILP algorithm can be used for an overall EEX (European Energy Exchange) optimised management of clustered CHP systems in form of the virtual power plant. This algorithm has been used to control cogeneration plants within a distribution grid. (author)

Part-load cogeneration technology meets chilled water and steam requirements  

Science Conference Proceedings (OSTI)

Louisiana State University`s Energy Savings Performance Contract with CES/Way was a groundbreaking project that applied part-load cogeneration technology to a large university campus to meet chilled water and steam requirements for expansion needs. Simultaneously, the project provided these utilities at no additional out of pocket cost to the institution by using the innovative financing mechanism of performance contracting, in which project savings pay for the investment. In addition, the work is performed via a cogeneration system operating most of the year at part-load. This mechanical cogeneration project could also be termed a thermal cogeneration project, as it provides a dual thermal benefit from a single input energy source. Not only did the project achieve the projected energy savings, but the savings proved to be so dependable that the University opted for an early buyout of the project from CES/Way in 1994, after only about two years of documented savings.

Modelling Residential-Scale Combustion-Based Cogeneration in Building Simulation  

SciTech Connect

This article describes the development, calibration and validation of a combustion-cogeneration model for whole-building simulation. As part of IEA Annex 42, we proposed a parametric model for studying residentialscale cogeneration systems based on both Stirling and internal combustion engines. The model can predict the fuel use, thermal output and electrical generation of a cogeneration device in response to changing loads, coolant temperatures and flow rates, and control strategies. The model is now implemented in the publicly-available EnergyPlus, ESP-r and TRNSYS building simulation programs. We vetted all three implementations using a comprehensive comparative testing suite, and validated the model's theoretical basis through comparison to measured data. The results demonstrate acceptable-to-excellent agreement, and suggest the model can be used with confidence when studying the energy performance of cogeneration equipment in non-condensing operation.

Thermodynamic and economic analysis of cogeneration steam cycles  

SciTech Connect

Thermodynamic models for two district heating, cogeneration steam cycles were developed in this study. These cycles are an extraction-condensing turbine cycle and a back-pressure turbine cycle. Heat and electrical outputs of these cycles were calculated for inlet conditions ranging from 580 psi, 752 F, to 1740 psi, 995 F (4 MPa, 400/sup 0/C to 12 MPa, 535/sup 0/C), and district heat supply temperatures ranging from 194 F to 248 F (90/sup 0/C to 120/sup 0/C). Furthermore, the performance of these cycles from 0 to 100% of their maximum heat outputs were examined. A simple method of economic analysis based on annual costs was developed, which can take part-load operations into consideration. An extraction-condensing system and a back-pressure system were compared using this method.

Project considerations and design of systems for wheeling cogenerated power  

SciTech Connect

Wheeling electric power, the transmission of electricity not owned by an electric utility over its transmission lines, is a term not generally recognized outside the electric utility industry. Investigation of the term`s origin is intriguing. For centuries, wheel has been used to describe an entire machine, not just individual wheels within a machine. Thus we have waterwheel, spinning wheel, potter`s wheel and, for an automobile, wheels. Wheel as a verb connotes transmission or modification of forces and motion in machinery. With the advent of an understanding of electricity, use of the word wheel was extended to be transmission of electric power as well as mechanical power. Today, use of the term wheeling electric power is restricted to utility transmission of power that it doesn`t own. Cogeneration refers to simultaneous production of electric and thermal power from an energy source. This is more efficient than separate production of electricity and thermal power and, in many instances, less expensive.

Natural Gas Procurement Challenges for a Project Financed Cogeneration Facility  

E-Print Network (OSTI)

A decision to project finance a 110 megawatt combined cycle cogeneration facility in 1986 in place of conventional internal financing greatly changed the way in which natural gas was normally procured by Union Carbide Corporation. Natural gas supply security for the term of financing was a major concern of the financing interest, while competitive fuel cost greatly concerned Union Carbide. In addition, the natural gas contract had to be in place prior to construction financing finalization. This paper will explore the thought process that went into evaluating the various natural gas supply proposals that ultimately resulted in the final contractual arrangements. While the information presented will be deliberately non-specific to the suppliers involved or the contractual terms, the discussion will cover the following areas: PROJECT FINANCING REQUIREMENTS, GAS SUPPLY CONSIDERATIONS, SUPPLY TRANSPORTATION EXPEDITIOUS INTERNAL APPROVAL, and SUPPLIER INTANGIBLES.

Co-generation at CERN Beneficial or not?  

E-Print Network (OSTI)

A co-generation plant for the combined production of electricity and heat has recently been installed on the CERN Meyrin site. This plant consists of: a gas turbine generator set (GT-set), a heat recovery boiler for the connection to the CERN primary heating network, as well as various components for the integration on site. A feasibility study was carried out and based on the argument that the combined use of natural gas -available anyhow for heating purposes- gives an attractively high total efficiency, which will, in a period of time, pay off the investment. This report will explain and update the calculation model, thereby confirming the benefits of the project. The results from the commissioning tests will be taken into account, as well as the benefits to be realized under the condition that the plant can operate undisturbed by technical setbacks which, incidentally, has not been entirely avoided during the first year of test-run and operation.

Advances in coal-fueled gas turbine technology over the past few years, together with recent DOE-METC sponsored studies, have served to provide new optimism that the problems demonstrated in the past can be economically resolved and that the coal-fueled gas turbine can ultimately be the preferred system in appropriate market application sectors. The objective of the Solar/METC program is to prove the technical, economic, and environmental feasibility of a coal-fired gas turbine for cogeneration applications through tests of a Centaur Type H engine system operated on coal fuel throughout the engine design operating range. The five-year program consists of three phases, namely: (1) system description; (2) component development; (3) prototype system verification. A successful conclusion to the program will initiate a continuation of the commercialization plan through extended field demonstration runs.

Operating and Maintaining a 465MW Cogeneration Plant  

E-Print Network (OSTI)

The on-line avilability of the five Frame-7E gas turbine generators installed at the 465MW Lyondell Cogeneration Plant was 90% and 95.2% respectively for the first two years of operation (1986-87). The 140MW steam turbine generator availability was well over 98% each year. Such favorable results are due primarily to the (1) formal training programs utilized before and continued after plant startup, (2) redundancies designed into the critical components of the plant, (3) the immediate actions taken on failures or near-failures, (4) a sound preventive maintenance program, and (5) improvements performed promptly on discovered design, operating, and maintenance weaknesses uncovered during the early months of operation.

Models for Short-Term Production Planning of Cogeneration Plants  

E-Print Network (OSTI)

The short-term production planning problem for a district heating system is a well-known but difficult optimization problem. In a district heating plant several types of energy producing units are used, the most important being the cogeneration unit, which produces both heat and electricity. The net electricity is sold at the electricity market. Most plants also have a heat water storage. Finding the optimal production of both heat and electricity and the optimal use of the heat water storage is a challenging mixed optimization problem. The production planning may be divided into two sub-problems. The unit commitment problem determines which units should be on or off and in which different mode the unit should run. The economic dispatch problem finds the optimal production plan given the units on and running modes. In this paper we formulate a new approach for the mathematical modeling of the economic dispatch problem. The model objective function is nonlinear, with nonlinear constrain...

Application of Thermal Storage, Peak Shaving and Cogeneration for Hospitals  

E-Print Network (OSTI)

Energy costs of hospitals can be managed by employing various strategies to control peak electrical demand (KW) while at the same time providing additional security of operation in the event that an equipment failure or a disruption of power from the electric utility occurs. Some electric utilities offer their customers demand (KW) reduction rate incentives. Many hospitals have additional emergency back-up needs for electrical energy. Demand is relatively constant in many hospitals due to high internal loads. These factors coupled with the present competitive alternate fuel market and present opportunities for hospitals to significantly reduce operating costs and provide additional stand-by or back-up electric sources. This paper employs a hospital case study to define and illustrate three energy planning strategies applicable to hospitals. These strategies are peak shaving, thermal storage, cogeneration and/or paralleling with the electric utility.

Cogeneration Design Considerations for a Major Petrochemical Facility  

E-Print Network (OSTI)

The step increase in energy cost brought about in 1973 has permanently changed the way in which petrochemical production facilities are designed, operated, and maintained. Highly visible energy conservation programs consisting of steam trap repair, insulation, and turning off unused equipment in the late 1970’s gave way to industrial wide shutdown of older, less efficient production facilities in the 1980’s. The subject petrochemical facility’s energy use peaked in early 1981. Several small projects were instituted to accommodate a declining steam load and increasing amounts of low pressure steam venting. However, as steam load was dropping, electrical rates were increasing both from rising natural gas costs and utility construction of a nuclear power plant. As a result, energy costs seemed almost an uncontrollable cost in late 1982. This paper addresses the design considerations and the following distinct steps taken in the development process of a 100 megawatt cogeneration power plant currently under construction at the petrochemical facility. The paper addresses the following distinct steps taken in the design process. 1. Examination of past, current, and future electricity and steam demand. 2. Examination of the regulatory climate and opportunities for firm power sales. 3. Economic evaluation of different fuel and power cost projections and their impact on cycle and equipment selection. 4. Evaluation of the reliability required by current and associated future standby power contracts. 5. Examination of outside forces that impact the design. 6. Selection of final design. The above considerations led to a unique efficient design that incorporates 100% steam condensing capability and independent dual train operating capability. The subject cogeneration plant is scheduled to be in full operation in December of 1987.

Evaluation of the heating operation and transmission district: Feasibility of cogeneration. Final report  

Science Conference Proceedings (OSTI)

The General Services Administration, through its National Capital Region, operates a district heating system - called the Heating Operation and Transmission District - that provides steam to approximately 100 government buildings in Washington, D.C. HOTD is examining a host of options that will improve its ability to provide reliable, environmentally sound, and cost-effective service to its customers. This report evaluates one of those options - cogeneration, a technology that would enable HOTD to produce steam and electricity simultaneously. The study concluded that, under current regulations, cogeneration is not attractive economically because the payback period (15 years) exceeds Federal return-on-investment guidelines. However, if the regulatory environment changes to allow wheeling (transmission of power by a non-utility power producer to another user), cogeneration would be attractive; HOTD would save anywhere from $38 million to $118 million and the investment would pay back in 7 to 10 years. Although incorporating cogeneration into the HOTD system has no strong benefit at this time, the report recommends that GSA reevaluate cogeneration in one or two years because Federal regulations regarding wheeling are under review. It also recommends that GSA work with the District of Columbia government to develop standards for cogeneration.

Analysis of Homogeneous Charge Compression Ignition (HCCI) Engines for Cogeneration Applications  

SciTech Connect

This paper presents an evaluation of the applicability of Homogeneous Charge Compression Ignition Engines (HCCI) for small-scale cogeneration (less than 1 MWe) in comparison to five previously analyzed prime movers. The five comparator prime movers include stoichiometric spark-ignited (SI) engines, lean burn SI engines, diesel engines, microturbines and fuel cells. The investigated option, HCCI engines, is a relatively new type of engine that has some fundamental differences with respect to other prime movers. Here, the prime movers are compared by calculating electric and heating efficiency, fuel consumption, nitrogen oxide (NOx) emissions and capital and fuel cost. Two cases are analyzed. In Case 1, the cogeneration facility requires combined power and heating. In Case 2, the requirement is for power and chilling. The results show that the HCCI engines closely approach the very high fuel utilization efficiency of diesel engines without the high emissions of NOx and the expensive diesel fuel. HCCI engines offer a new alternative for cogeneration that provides a unique combination of low cost, high efficiency, low emissions and flexibility in operating temperatures that can be optimally tuned for cogeneration systems. HCCI engines are the most efficient technology that meets the oncoming 2007 CARB NOx standards for cogeneration engines. The HCCI engine appears to be a good option for cogeneration systems and merits more detailed analysis and experimental demonstration.

Derwent cogeneration renews steam supply to Courtauld`s  

SciTech Connect

A 220 MW gas turbine CHP scheme replaces coal-fired boilers at Courtauld`s power station, near Derby, England. It provides steam both to processes and to drive the three existing back-pressure turbines. The scheme that has evolved comprises four MS6001B gas turbines, with fired dual-pressure heat recovery boilers and a 58 MW condensing steam turbine. The plant is of outdoor construction, sited next to the existing Spondon H. With the original coal-fired boilers now decommissioned, the three back-pressure turbines bridge across the HP and LP steam outputs of the new plant. The plant is designed for dual-fuel operation, but in practice will burn only gas. The plant was completed in March this year and was available as an emergency steam supply to cover outages in the coal-fired plant. 6 figs.

An Application of Integrated Thermal and Electrical Energy Cogeneration Optimization  

E-Print Network (OSTI)

The savings associated with operations optimization of power generation and cogeneration facilities are large, and readily justify the hardware and software costs required for implementation of Energy Management Optimization Systems (EMOS). The objective of such systems is to minimize the total energy operating costs for specified power and steam load profiles, including the purchase of external power and/or steam, and the use of internal self-generation equipment. The EMOS may require online operation using current measurements (e.g. flow, powers, temperatures, etc.), and calculating optimum energy purchase and equipment dispatch within time periods consistent with changing ambients, loads and/or purchase energy price conditions. The automatic recognition of changes in equipment status and system operating configuration may be required. The EMOS may also consider the electrical distribution system to minimize losses, and to ensure that tbe optimum thermal power dispatch may be reliably delivered to the loads under tbe existing distribution configuration within electrical equipment operating limits. Automatic generation dispatch may also be required. A system which incorporates the requirements of the above specification and more, has been designed, installed and is operational at a large industrial cogeneration facility. A description of the specifics of this entire system is beyond tbe scope of this paper, however, a discussion of selected system features will be given. This application involves the simultaneous optimization of energy supply for in-plant power and process steam from many highly integrated system components. Cogeneration plants, as shown in Figure 1, are generally characterized by multiple sources of energy, various types of prime movers (e.g. boilers, waste heat recovery, steam and gas turbines, etc.), and varying requirements for process heat and electrical power, particularly if bulk power is being purchased, or dispatched to a utility grid as in the case of Independent Power Producers. In addition, the operating characteristics of tbe equipment and loads are continuously changing due to outage of equipment, changes in process steam and electrical demands, ambient conditions and performance deterioration. The ability to coordinate and optimize the simultaneous operation of the various components to meet all the energy requirements at minimum cost is a formidable task. In addition to the thermal optimization of boilers, gas turbines, and various types of condensing and autoextraction steam turbines, the system also considers the electrical distribution system, where changing bus configurations, power and voltage control impose additional constraints and limits which are solved in the optimum dispatch. The application incorporates automatic closed loop control of many process set points with a sophisticated system of permissives and automatic generation control features. Since a high on-line operating factor is essential, many design features are incorporated for signal validation and malfunction identification, and to make the system robust to instrument failure and drift. The system can be used as an on-line or off-line supervisory program. For on line implementation, closed loop response, fail safe operation and interfacing with process control systems are key closed loop implementation considerations. The system involves the interaction of several modules. The following will describe selected modules and how they interface to satisfy existing loads at minimum cost.

Evaluation of diurnal thermal energy storage combined with cogeneration systems. Phase 2  

DOE Green Energy (OSTI)

This report describes the results of a study of thermal energy storage (TES) systems integrated with combined-cycle gas turbine cogeneration systems. Integrating thermal energy storage with conventional cogeneration equipment increases the initial cost of the combined system; but, by decoupling electric power and process heat production, the system offers two significant advantages. First, electric power can be generated on demand, irrespective of the process heat load profile, thus increasing the value of the power produced. Second, although supplementary firing could be used to serve independently varying electric and process heat loads, this approach is inefficient. Integrating TES with cogeneration can serve the two independent loads while firing all fuel in the gas turbine. An earlier study analyzed TES integrated with a simple-cycle cogeneration system. This follow-on study evaluated the cost of power produced by a combined-cycle electric power plant (CC), a combined-cycle cogeneration plant (CC/Cogen), and a combined-cycle cogeneration plant integrated with thermal energy storage (CC/TES/Cogen). Each of these three systems was designed to serve a fixed (24 hr/day) process steam load. The value of producing electricity was set at the levelized cost for a CC plant, while the value of the process steam was for a conventional stand-alone boiler. The results presented here compared the costs for CC/TES/Cogen system with those of the CC and the CC/Cogen plants. They indicate relatively poor economic prospects for integrating TES with a combined-cycle cogeneration power plant for the assumed designs. The major reason is the extremely close approach temperatures at the storage media heaters, which makes the heaters large and therefore expensive.

Cogeneration and community design: performance based model for optimization of the design of U.S. residential communities utilizing cogeneration systems in cold climates  

E-Print Network (OSTI)

The integration of cogeneration technologies in residential communities has the potential of reducing energy demand and harmful emissions. This study investigated the impact of selected design parameters on the environmental and economic performances of cogeneration systems integrated into residential communities in cold U.S. climates following a centralized or a decentralized integration approach. Parameters investigated include: 1) density, 2) use mix, 3) street configuration, 4) housing typology, 5) envelope and building systems' efficiencies, 6) renewable energy utilization, 7) cogeneration system type, 8) size, and 9) operation strategy. Based on this, combinations of design characteristics achieving an optimum system performance were identified. The study followed a two-phased mixed research model: first, studies of residential community design and three case studies of sustainable residential communities were analyzed to identify key design parameters; subsequently, simulation tools were utilized to assess the impact of each parameter on cogeneration system performance and to optimize the community design to improve that performance. Assessment procedures included: developing a base-line model representing typical design characteristics of U.S. residential communities; assessing the system performance within this model, for each integration approach, using three performance indicators: reduction in primary energy use, reduction in CO2 emissions; and internal rate of return; assessing the impact of each parameter on the system performance through developing 46 design variations of the base-line model representing changes in these parameters and calculating the three indicators for each variation; using a multi-attribute decision analysis methodology to evaluate the relative impact of each parameter on the system performance; and finally, developing two design optimization scenarios for each integration approach. Results show that, through design optimization, existing cogeneration technologies can be economically feasible and cause reductions of up to 18% in primary energy use and up to 42% in CO2 emissions, with the centralized approach offering a higher potential for performance improvements. A significant correlation also existed between design characteristics identified as favorable for cogeneration system performance and those of sustainable residential communities. These include high densities, high mix of uses, interconnected street networks, and mixing of housing typologies. This indicates the higher potential for integrating cogeneration systems in sustainable residential communities.

Promotion of Biomass Cogeneration With Power Export in the Indian Sugar  

NLE Websites -- All DOE Office Websites (Extended Search)

Promotion of Biomass Cogeneration With Power Export in the Indian Sugar Industry Promotion of Biomass Cogeneration With Power Export in the Indian Sugar Industry India Helping Reduce the Risk of Global Warming Greenhouse Gas Pollution Prevention (GEP) Project in India India is the worldÂ’s fifth largest, and second fastest growing, source of greenhouse gas emissions. The GEP Project, conducted under an agreement with USAID-India and NETL, has helped to reduce greenhouse gas emissions from coal- and biomass-fired power plants. The Project has directly contributed to reducing emissions of CO2 by 6 to 10 million tons per year. India is the largest producer of sugar and also contains vast reserves of coal. Under the ProjectÂ’s Advanced Bagasse Cogeneration Component, cogeneration (production of electricity and steam) using biomass fuels year-round in high efficiency boilers in sugar mills is promoted. Experts feel that, using the concept of sugar mill cogeneration, that as much as 5,000 megawatts of electricity can be generated through efficient combustion of bagasse in Indian sugar mills.

Optimizing Process Loads in Industrial Cogeneration Energy Systems  

E-Print Network (OSTI)

Optimum dispatch of energy supply systems can result in large savings in industrial facilities. Identifying the configuration of available equipment, and its loading to minimize total energy consumption to satisfy given load demands, has very high payback potential. This paper discusses an approach to determine integrated energy supply and end use optimum equipment dispatch to simultaneously satisfy given power, process steam and additional "end energy" product needs such as compressed fluids, chemical unit production, etc. Techniques applied to power generation and industrial cogeneration are extended to solving this trigeneration problem where the optimum dispatch of the final load devices (i.e. compressors, fans, pumps, etc.) are an integral part of the total energy system optimization. An example industrial trigeneration system is discussed to illustrate the application and procedures. The methods of considering alternate energy sources, for end use optimization with export power and steam generation will be illustrated. The savings associated with operations optimization readily justify the hardware and software costs required for implementation of Optimization Energy Management Systems (OEMS). An OEMS capability for this application is briefly discussed.

Algorithms for Short-Term Production-Planning of Cogeneration Plants  

E-Print Network (OSTI)

A cogeneration plant, feeding its output water into a district-heating network, may include several types of energy producing units. The most important being the Cogeneration unit, which produces both heat and electricity. Most plants also have a Heat water storage. Finding the optimal production of both heat and electricity and the optimal use of the storage is a challenging mixed integer nonlinear optimization problem. The calculations may be divided into two sub-problems. The unit commitment problem is the problem to determine when a unit should be producing (on) or not (off). To solve the economic dispatch problem is to find the optimal production plan given which units are producing in each time interval. Together the solution of these two problems form the solution of the short-term production-planning problem. In this thesis a general approach for the mathematical modeling of a cogeneration plant is presented. The model objective function is nonlinear, with nonlinear constraints....

Osaka Gas and Tokyo Gas have high expectations for natural-gas-fueled Solid Oxide Fuel Cell (SOFC) cogeneration systems. SOFC offers many advantages for on-site cogeneration systems, such as high electrical efficiency, high quality by-product heat and low emissions. They are now executing a joint development program with Westinghouse Electric Corporation (hereinafter called as WELCO). This program is aimed to verify a 25kW class SOFC cogeneration system. This system, which was modified by replacing previous zirconia porous support tube cells (PST cells) with newly designed air electrode supported cells (AES cells), commenced operation on March 21, 1995. The system has been successfully operated for 13,100 hours as of February 7, 1997. This paper presents the performance evaluation of the new AES cells and the results of system operation at WELCO.

Optimization of Combustion Efficiency for Supplementally Fired Gas Turbine Cogenerator Exhaust Heat Receptors  

E-Print Network (OSTI)

A broad range of unique cogeneration schemes are being installed or considered for application in the process industries involving gas turbines with heat recovery from the exhaust gas. Depending on the turbine design, exhaust gases will range from 800 to 1000 F with roughly 15 to 18 percent remaining oxygen. The overall heat utilization efficiency and the net effective heat rate of the cogenerating facility varies widely with the degree of supplemental firing of the heat receptor. This effect is explained and its economic significance defined. Other effects are also explored, such as adiabatic and equilibrium combustion temperatures; and variations in radiant versus convection heat transfer in the heat receptor furnace or boiler.

Experiences with titanium next-to-last LP blades in a 1300 MW turbine  

SciTech Connect

The use of titanium as a material for the end blades of LP turbines has already been investigated twenty years ago by Brown Boveri. Next-to-last LP blades in the past have several times been the cause of turbine damage, because these blades work in the zone of the first condensation and thus are subjected to mechanical stress in corrosive environment. Favorable corrosion properties of titanium provided a reason for developing and manufacturing two next-to-last titanium low pressure blade rows in 1980 and to use them in a 1300 MW plant. On the occasion of an overhaul, a visual check was carried out of the titanium blades and chemical analysis of the blade surface deposits were made. From the distribution of the deposits conclusions can be drawn, retroactively, as to why steel blades might have failed. The titanium blades are undergoing a further operation period.

Exergetic, thermal, and externalities analyses of a cogeneration plant  

SciTech Connect

A thermodynamic study of an 88.4 MW cogeneration plant located in the United States is presented in this paper. The feedstock for this actual plant is culm, the waste left from anthracite coal mining. Before combustion in circulating fluidized bed boilers, the usable carbon within the culm is separated from the indigenous rock. The rock and ash waste from the combustion process fill adjacent land previously scared by strip mining. Trees and grass are planted in these areas as part of a land reclamation program. Analyses based on the first and second laws of thermodynamics using actual operating data are first presented to acquaint the reader with the plant's components and operation. Using emission and other relevant environmental data from the plant, all externalities study is outlined that estimates the plant's effect on the local population. The results show that the plant's cycle performs with a coefficient of utilization of 29% and all approximate exergetic efficiency of 34.5%. In order to increase these values, recommended improvements to the plant are noted. In addition, the externality costs associated with the estimated SO{sub 2} and NOx discharge from the culm fed plant are lower (85-95%) than those associated with a similarly sized coal fed plant. The plant's cycle efficiencies are lower than those associated with more modern technologies; such as all integrated gas turbine combined cycle. However, given the abundant, inexpensive supply of feedstock located adjacent to the plant and the environmental benefit of removing culm banks, the plant's existing operation is unique from an economical and environmental viewpoint.

The Behavior of Lakes  

NLE Websites -- All DOE Office Websites (Extended Search)

Behavior of Lakes Behavior of Lakes Nature Bulletin No, 320-A November 9, 1968 Forest Preserve District of Cook County Richard B. Ogilvie, President Roland F. Eisenbeis, Supt. of Conservation THE BEHAVIOR OF LAKES In many ways lakes are like living things -- especially a tree. A lake breathes and has a circulation; it is warmed and fed; it harbors many other living things; and in cold weather it goes into a winter sleep. If it were not for the special character of a body of standing water which we call a lake, the things that live in it would be radically different or, perhaps, not exist at all. Water is a very strange substance in many ways. For example, it is remarkable because it expands, becomes lighter and floats when it freezes into ice. If, like most substances, water shrank when it changed from a liquid to a solid, it would sink. Then, ponds and lakes would freeze from the bottom up and become solid blocks of ice. This would make life impossible for most kinds of aquatic plants and animals and indirectly affect all living things. Further, water is a poor conductor of heat -- otherwise lakes would freeze much deeper and, again most living things in it would perish.

Cogeneration : A Regulatory Guide to Leasing, Permitting, and Licensing in Idaho, Montana, Oregon, and Washington.  

Science Conference Proceedings (OSTI)

This guidebook focuses on cogeneration development. It is one of a series of four guidebooks recently prepared to introduce the energy developer to the federal, state and local agencies that regulate energy facilities in Idaho, Montana, Oregon, and Washington (the Bonneville Power Administration Service Territory). It was prepared specifically to help cogeneration developers obtain the permits, licenses and approvals necessary to construct and operate a cogeneration facility. The regulations, agencies and policies described herein are subject to change. Changes are likely to occur whenever energy or a project becomes a political issue, a state legislature meets, a preexisting popular or valuable land use is thought threatened, elected and appointed officials change, and new directions are imposed on states and local governments by the federal government. Accordingly, cogeneration developers should verify and continuously monitor the status of laws and rules that might affect their plans. Developers are cautioned that the regulations described herein may only be a starting point on the road to obtaining all the necessary permits.

HTGR-GT closed-cycle gas turbine: a plant concept with inherent cogeneration (power plus heat production) capability  

SciTech Connect

The high-grade sensible heat rejection characteristic of the high-temperature gas-cooled reactor-gas turbine (HTGR-GT) plant is ideally suited to cogeneration. Cogeneration in this nuclear closed-cycle plant could include (1) bottoming Rankine cycle, (2) hot water or process steam production, (3) desalination, and (4) urban and industrial district heating. This paper discusses the HTGR-GT plant thermodynamic cycles, design features, and potential applications for the cogeneration operation modes. This paper concludes that the HTGR-GT plant, which can potentially approach a 50% overall efficiency in a combined cycle mode, can significantly aid national energy goals, particularly resource conservation.

The National LP-Gas Association reports that sales of LP-gas rose 4.0% in 1976 to an estimated 15.81 billion gal. Residential and commercial sales accounted for 7.13 billion gal, a 1.6% increase; sales to the chemical industry 4.41 billion, 5.6% more; the engine-fuel market 1.17 billion, up 0.5%; and utility sales 0.45 billion, a 12.0% rise. Industrial sales declined 1.3% to 1.07 billion gal in 1976. The ''other'' category, including agricultural uses and feedstock for the manufacture of synthetic gas, jumped 16.8% to 1.60 billion gal. U.S. production of LPG declined 0.4% to 18.02 billion gal, while imports rose 12.3% to 1.94 billion gal. The difference between production and sales is accounted for by the use of LPG in gasoline blending, inventory additions, and exports.

Commissioning and Start Up of a 110 MegaWatt Cogeneration Facility  

E-Print Network (OSTI)

"In December of 1987, Union Carbide successfully brought on line a 110,000 KVA combined cycle cogeneration facility. The construction, commissioning and start up of this complex facility was accomplished in a remarkably short twelve months. As with all projects of any magnitude, there were several technical challenges that developed during the course of the year. These challenges and the Project Team response will be discussed in some detail. Some areas include: 1. Procurement 2. Technical review of specs and drawings 3. Existing manufacturing facility constraints 4. Mechanical problems 5. Electrical problems 6. Control system / instrumentation problems The commissioning and start up had to be coordinated with existing Plant operations. As a result of the Project Team's efforts, the cogeneration facility achieved 100% of design output on December 22, 1987 without any significant impact on the manufacturing facility."

Potential impact of consumer choice on cogenerator's short-run price and output decisions  

SciTech Connect

Conditions were derived under which optimal price-output combinations can be determined for a profit-maximizing cogenerator faced with a demand constraint for useful energy. Four cases were considered. In two cases, all energy produced was sold to the end-use market and, in the other two, some electricity was sold to the grid. The effects of price regulation on energy output were also covered. In the short-run, in all four cases, whether or not the necessary conditions for Pareto optimality are satisfied is problematic. If the cogenerator monopolizes alternative supplies of energy, price regulation will not necessarily reduce energy expenditures. The short-term effects of constrained energy demand can only be determined with a knowledge of the cost and demand functions of thermal energy and electricity.

COGENMASTER: A model for evaluating cogeneration options: Final report, Volume 2, User's guide  

Science Conference Proceedings (OSTI)

The COGENMASTER model was developed in this project. COGENMASTER is a micro-computer based menu-driven model which enables the user to examine the technical aspects of various types of cogeneration projects, evaluate their economic feasibility, and prepare detailed cash flow statements that spell out the costs and benefits to project participants. The model is designed to objectively evaluate and screen cogeneration options by comparing them to a base case scenario in which electricity is purchased from the utility and thermal energy is produced on-site. The model consists of many modules that may be individually edited. The different modules that constitute COGENMASTER are the technology, load shape, rates, sizing, operating, cash-flow, financing, pricing and simulation modules. A load shape library of electric and thermal loads in nine commercial buildings and seven weather zones was also developed as part of this project. In addition, a technology database of six generic cogeneration systems is also included in the package. The model has been written for IBM-PC compatible computers with 512K memory, a floppy drive and a hard disk.

Feasibility study of wood-fired cogeneration at a Wood Products Industrial Park, Belington, WV. Phase II  

DOE Green Energy (OSTI)

Customarily, electricity is generated in a utility power plant while thermal energy is generated in a heating/cooling plant; the electricity produced at the power plant is transmitted to the heating/cooling plant to power equipments. These two separate systems waste vast amounts of heat and result in individual efficiencies of about 35%. Cogeneration is the sequential production of power (electrical or mechanical) and thermal energy (process steam, hot/chilled water) from a single power source; the reject heat of one process issued as input into the subsequent process. Cogeneration increases the efficiency of these stand-alone systems by producing these two products sequentially at one location using a small additional amount of fuel, rendering the system efficiency greater than 70%. This report discusses cogeneration technologies as applied to wood fuel fired system.

Advanced cogeneration and absorption chillers potential for service to Navy bases. Final report  

SciTech Connect

The US military uses millions of Btu`s of thermal energy to heat, cool and deliver process thermal energy to buildings on military bases, much of which is transmitted through a pipeline system incorporating thousands of miles of pipe. Much of this pipeline system is in disrepair and is nearing the end of its useful life, and the boilers which supply it are old and often inefficient. In 1993, Brookhaven National Laboratory (BNL) proposed to SERDP a three-year effort to develop advanced systems of coupled diesel cogenerators and absorption chillers which would be particularly useful in providing a continuation of the services now provided by increasingly antiquated district systems. In mid-February, 1995, BNL learned that all subsequent funding for our program had been canceled. BNL staff continued to develop the Program Plan and to adhere to the requirements of the Execution Plan, but began to look for ways in which the work could be made relevant to Navy and DoD energy needs even without the extensive development plan formerly envisioned. The entire program was therefore re-oriented to look for ways in which small scale cogeneration and absorption chilling technologies, available through procurement rather than development, could provide some solutions to the problem of deteriorated district heating systems. The result is, we believe, a striking new approach to the provision of building services on military bases: in many cases, serious study should be made of the possibility that the old district heating system should be removed or abandoned, and small-scale cogenerators and absorption chillers should be installed in each building. In the remainder of this Summary, we develop the rationale behind this concept and summarize our findings concerning the conditions under which this course of action would be advisable and the economic benefits which will accrue if it is followed. The details are developed in the succeeding sections of the report.

JV 38-APPLICATION OF COFIRING AND COGENERATION FOR SOUTH DAKOTA SOYBEAN PROCESSORS  

DOE Green Energy (OSTI)

Cogeneration of heat and electricity is being considered by the South Dakota Soybean Processors for its facility in Volga, South Dakota, and a new facility to be located in Brewster, Minnesota. The Energy & Environmental Research Center has completed a feasibility study, with 40% funding provided from the U.S. Department of Energy's Jointly Sponsored Research Program to determine the potential application of firing biomass fuels combined with coal and comparative economics of natural gas-fired turbines. Various biomass fuels are available at each location. The most promising options based on availability are as follows. The economic impact of firing 25% biomass with coal can increase return on investment by 0.5 to 1.5 years when compared to firing natural gas. The results of the comparative economics suggest that a fluidized-bed cogeneration system will have the best economic performance. Installation for the Brewster site is recommended based on natural gas prices not dropping below a $4.00/MMBtu annual average delivered cost. Installation at the Volga site is only recommended if natural gas prices substantially increase to $5.00/MMBtu on average. A 1- to 2-year time frame will be needed for permitting and equipment procurement.

Design and Economic Evaluation of Thermionic Cogeneration in a Chlorine-Caustic Plant  

E-Print Network (OSTI)

The study shows that it is feasible to equip a chlorine-caustic plant with thermionic cogeneration. Thermionic combustors replace the existing burners of the boilers used to raise steam for the evaporators, and are capable of generating approximately 2.6 MW of dc power. This satisfies about 5 percent of the power demand of the chlorine cells. More thermionic power could be generated, and excess steam would be produced which could be sold or used elsewhere in the plant. A typical plant was defined based on a survey of U.S. chlorine plants. This plant produces 470 U.S. tons of chlorine per day, with four cell rooms. Each cell room is one electrical circuit and requires a dc supply of 185 V and 70,000 A. Total dc power consumption is nearly 13 MW. The steam for the evaporators is raised in four boilers with a total installed capacity of 320,000 Ib of steam per hour. The study shows that the estimated cost of thermionic cogeneration installed in the typical chlorine-caustic plant is $1600 per kW.

Small-Scale Industrial Cogeneration: Design Using Reciprocating Engines and Absorption Chillers  

E-Print Network (OSTI)

This paper describes a packaged cogeneration system designed for light industrial applications (i.e., situations where a user wants a maximum of 1 MW of cogenerated electricity). The design employs reciprocating engines fueled with natural gas or liquid fuels. Waste heat from the engine exhaust and jacket water is used to drive an absorption chiller. This approach yields a variety of unique advantages, including: (1) ability to satisfy the needs of facilities that have a low ratio of thermal-to-electric energy needs, and which have significant refrigeration loads, and (2) the ability to provide greater operating efficiency in the <1 MW size range, especially at part load, when compared to systems based on gas turbines or steam turbines. Although component substitution can be used to vary the energy output capabilities of the system, the discussion focuses on a unit having an electrical rating of 418 kW and cooling capacity of 160 tons. This paper discusses component selection, operating parameters, economics, maintenance issues, and other factors.

Evaluation of Industrial Energy Options for Cogeneration, Waste Heat Recovery and Alternative Fuel Utilization  

E-Print Network (OSTI)

This paper describes the energy options available to Missouri industrial firms in the areas of cogeneration, waste heat recovery, and coal and alternative fuel utilization. The project, being performed by Synergic Resources Corporation for the Missouri Division of Energy, identifies and evaluates technological options and describes the current status of various energy resource conservation technologies applicable industry and the economic, institutional and regulatory factors which could affect the implementation and use of these energy technologies. An industrial energy manual has been prepared, identifying technologies with significant potential for application in a specific company or plant. Six site-specific industrial case studies have been performed for industries considered suitable for cogeneration, waste heat recovery or alternative fuel use. These case studies, selected after a formal screening process, evaluate actual plant conditions and economics for Missouri industrial establishments. It is hoped that these case studies will show, by example, some of the elements that make energy resource conservation technologies economically a technically feasible in the real world.

Backpressure Steam Cogeneration: A History and Review of the "Cheapest Power You'll Never Buy"  

E-Print Network (OSTI)

The use of backpressure steam turbines to make low-cost electricity is a well established technology with a long and illustrious history and a value that became lost as industry switched from home-grown power generation to centralized utility power in the 30's and 40's. Cogeneration, once the normal and very efficient way of making power for most industries, cities, and even small towns, was left behind as utilities gradually moved toward large central station plants located far from city centers or industries that could serve as thermal loads. As a result, the average efficiency of electricity production dropped from 85% to 35% from 1935 to 1975. Now, however, the utility paradigm is changing again as deregulation spreads from state to state with its promise of more competition and better pricing for electricity users, and its accompanying proliferation of new rules and new players. In this environment, the value of a technology that allows industries and institutions to make cheap power as a function of their thermal load is re-emerging. This paper will review the history of backpressure steam cogeneration; the particular market niche of small systems -those under 10 MW; the advent of packaged systems and the advantages these bring to the under 10 MW market; and why this technology is particularly beneficial in a deregulated environment. We will also review the required circumstances for a successful project, and review first-pass financial evaluation techniques. Finally we will describe a few systems currently in use.

Economic analysis of coal-fired cogeneration plants for Air Force bases  

SciTech Connect

The Defense Appropriations Act of 1986 requires the Department of Defense to use an additional 1,600,000 tons/year of coal at their US facilities by 1995 and also states that the most economical fuel should be used at each facility. In a previous study of Air Force heating plants burning gas or oil, Oak Ridge National Laboratory found that only a small fraction of this target 1,600,000 tons/year could be achieved by converting the plants where coal is economically viable. To identify projects that would use greater amounts of coal, the economic benefits of installing coal-fired cogeneration plants at 7 candidate Air Force bases were examined in this study. A life-cycle cost analysis was performed that included two types of financing (Air Force and private) and three levels of energy escalation for a total of six economic scenarios. Hill, McGuire, and Plattsburgh Air Force Bases were identified as the facilities with the best potential for coal-fired cogeneration, but the actual cost savings will depend strongly on how the projects are financed and to a lesser extent on future energy escalation rates. 10 refs., 11 figs., 27 tabs.

Evaluation of potential for cogeneration of electricity and process heat in North Carolina. Final report, June 1, 1978-May 31, 1979  

SciTech Connect

The objective of this study was to enable North Carolina to more efficiently utilize available energy than would be possible without additional cogeneration. Effective use of cogeneration can ease the requirement for utility capital and power plant sites and, by reducing fuel usage, can lead to less environmental damage. The study used the National Emissions Data System data bank and the North Carolina Boiler Registry to identify potential candidates for cogeneration and to then ascertain the magnitude of the potential in existing, new, and expanded facilities as a function of cogeneration impediment elimination. The survey uncovered 372 MW of operable cogeneration capacity in North Carolina in 15 plants. An estimate of the potential for expansion of cogeneration by firms presently operating in North Carolina amounted to 130 MW. This estimate was based on current conditions of fuel costs, electricity rates, standby charges, and investment tax credit. Much information is provided concerning industry and utilities in North Carolina, fuel usage by industry, and barriers to cogeneration. Recommendations are summarized.

Why Sequence Great Salt Lake?  

NLE Websites -- All DOE Office Websites (Extended Search)

Great Salt Lake? Great Salt Lake? On average, the Great Salt Lake is four times saltier than the ocean and also has heavy metals, high concentrations of sulfur and petroleum seeps. In spite of all this, the lake is the saltiest body of water to support life. The lake hosts brine shrimp, algae and a diverse array of microbes, not to mention the roughly 5 million birds that migrate there annually. The secret to these microbes' ability to survive under such harsh conditions might be revealed in their genes. Researchers expect the genetic data will provide insight into how the microorganisms tolerate pollutants such as sulfur and detoxify pollutants such as sulfur and heavy metals like mercury. The information could then be used to develop bioremediation techniques. Researchers also expect that sequencing microorganisms sampled

Potential benefits of thermal energy storage in the proposed Twin Cities district heating-cogeneration system. Final report  

DOE Green Energy (OSTI)

A new, large, cogeneration-district heating system has been proposed for the Twin Cities area, using hot water in a closed-loop system. The proposed system, as described by Studsvik Energiteknik AB of Sweden, does not employ thermal energy storage (TES). Four cases have been developed, describing system configurations which would employ TES, to evaluate the potential benefits of incorporating annual-cycle TES into the Twin Cities system. The potential benefits are found to be substantial, confirming results of earlier, generic studies of aquifer TES. The reference (Studsvik) system employs oil-fired boilers to supplement cogenerated heat, for handling peak loads and providing standby reserve. TES can serve the same function, with net energy savings in spite of heat losses during storage, by making it possible to operate the cogeneration equipment at higher capacity factors. Coal replaces oil as the fuel consumed. Energy savings of the reference system are impressive; energy savings with TES are 2 to 22% better. Capital cost requirements for boilers, cogeneration equipment, and pipelines are reduced by $66 to $258 million. The breakeven capital cost of TES is estimated to range from $43 to $76 per kilowatt peak thermal input to or withdrawal from aquifer TES. A factor in evaluating the breakeven operating cost of TES is the $14 to $31 million per year saving in cost of fuel. Abatement of air pollution and thermal pollution are concomitant benefits.

Feasibility of geothermal space/water heating for Mammoth Lakes Village, California. Final report, September 1976--September 1977  

DOE Green Energy (OSTI)

Results of a study to determine the technical, economic, and environmental feasibility of geothermal district heating for Mammoth Lakes Village, California are reported. The geothermal district heating system selected is technically feasible and will use existing technology in its design and operation. District heating can provide space and water heating energy for typical customers at lower cost than alternative sources of energy. If the district heating system is investor owned, lower costs are realized after five to six years of operation, and if owned by a nonprofit organization, after zero to three years. District heating offers lower costs than alternatives much sooner in time if co-generation and/or DOE participation in system construction are included in the analysis. During a preliminary environmental assessment, no potential adverse environmental impacts could be identified of sufficient consequence to preclude the construction and operation of the proposed district heating system. A follow-on program aimed at implementing district heating in Mammoth is outlined.

In summer absorption refrigerating machines provide cold water using excess heat from municipal thermoelectric power plant through district heating pipelines, which reduces peak electric load from electricity networks in summer. The paper simulates annual dynamic load of a real project to calculate the first investments, annual operation cost and LCC (life cycle cost) of the four schemes, which are electric chillers, electric chillers with ice-storage system, absorption refrigerating machines using excess heat from power plant and absorption refrigerating machines using excess heat from power plant along with ice-storage system. On the basis of the results, the paper analyzes the prospect of the absorption refrigeration using municipal excess heat, as well as the reasonable heat price, which provides a theoretical basis for municipal heating and cooling co-generation development.

Integration of Biorefineries and Nuclear Cogeneration Power Plants - A Preliminary Analysis  

SciTech Connect

Biomass-based ethanol and nuclear power are two viable elements in the path to U.S. energy independence. Numerous studies suggest nuclear power could provide a practical carbon-free heat source alternative for the production of biomass-based ethanol. In order for this coupling to occur, it is necessary to examine the interfacial requirements of both nuclear power plants and bioethanol refineries. This report describes the proposed characteristics of a small cogeneration nuclear power plant, a biochemical process-based cellulosic bioethanol refinery, and a thermochemical process-based cellulosic biorefinery. Systemic and interfacial issues relating to the co-location of either type of bioethanol facility with a nuclear power plant are presented and discussed. Results indicate future co-location efforts will require a new optimized energy strategy focused on overcoming the interfacial challenges identified in the report.

SciTech Connect

Demonstration of a direct coal-fueled gas turbine system that is environmentally, technically, and economically viable depends on the satisfactory resolution of several key issues. Solar Turbines, Incorporates technical approach to these issues was to advance a complete direct coal-fueled gas turbine system that incorporated near-term technology solutions to both historically demonstrated problem areas such as deposition, erosion, and hot end corrosion, and to the emergent environmental constraints based on NO{sub x}, SO{sub x}, and particulates. Solar`s program approach was keyed to the full commercialization of the coal-fueled cogeneration gas turbine which would occur after extended field verification demonstrations conducted by the private sector. The program was structured in three phases plus an optional fourth phase: Phase 1 -- system description; Phase 2 -- component development; Phase 3 -- prototype system verification; and Phase 4 -- field evaluation.

These cycles can be designed to accommodate a wide range of electrical, steam, and process heating demands. The optimum cycle is typically based on an analysis of the plant's electrical / steam / process heating requirements, an evaluation of the potential for selling to or permit wheeling by utilities of electrical power under PURPA guidelines, and application of pertinent investment decision criteria. The study that identifies the best solution to the problem must contain sufficient detail to support a plan of action by management. This paper addresses how computer-aided design techniques support the effort necessary to fully evaluate several alternative cycle designs in a short time frame. It includes examples for a new power unit as well as for cycles which require modifications to existing process and steam generating equipment in a medium-sized chemical plant.

Production Cost Modeling of Cogenerators in an Interconnected Electric Supply System  

E-Print Network (OSTI)

The Optimal State Electricity Supply System in Texas (OSEST) research project is part of the continuing Public Utility Commission of Texas (PUCT) effort to identify possible improvements in the production, transmission, and use of electricity in the state. The OSEST project is designed to identify the general configuration of the optimal electric supply system resulting from coordinated system planning and operation from a statewide perspective. The Optimized Generation Planning Program (OGP) and Multi-Area Production Simulation Program with Megawatt Flow (MAPS/MWFLOW) are two computer programs developed by General Electric that are being used in the study. Both of these programs perform production costing calculations to evaluate the performance of various electric supply system configurations necessary to appropriately model the present and future cogeneration activity in the service areas of the electric utilities that compose the Electric Reliability Council of Texas (ERCOT).

Cogenerator to quit Con Ed by selling kWh to neighbor  

SciTech Connect

Selling 125 kilowatts of electricity around the clock to a nearby supermarket will make cogeneration feasible for the Flagship Restaurant in White Plains, NY, allowing it to drop off Consolidated Edison's grid and pay for a necessary backup generator, according to John Prayias, the restaurant's owner. The ambitious $536,000 project, which will be financed conventionally with a commercial bank loan, will eliminate the Flagship's $70,000 electricity costs and the $7240 spent of heating and domestic hot water, Prayias said. By selling the power to the supermarket at 9 cents per kilowatt hour - 3 cents less than Con Ed's rate of 12 cents per kWh - the restaurant will collect $120,000 a year in revenues - just about enough to cover the cost of diesel fuel for the 350-kW system and pay for monitoring and maintenance.

Advanced coal-fueled industrial cogeneration gas turbine system. Annual report, June 1990--June 1991  

SciTech Connect

Advances in coal-fueled gas turbine technology over the past few years, together with recent DOE-METC sponsored studies, have served to provide new optimism that the problems demonstrated in the past can be economically resolved and that the coal-fueled gas turbine can ultimately be the preferred system in appropriate market application sectors. The objective of the Solar/METC program is to prove the technical, economic, and environmental feasibility of a coal-fired gas turbine for cogeneration applications through tests of a Centaur Type H engine system operated on coal fuel throughout the engine design operating range. The five-year program consists of three phases, namely: (1) system description; (2) component development; (3) prototype system verification. A successful conclusion to the program will initiate a continuation of the commercialization plan through extended field demonstration runs.

OPTIMIZATION FOR COGENERATION SYSTEMS IN BUILDINGS BASED ON LIFE CYCLE ASSESSMENT  

E-Print Network (OSTI)

SUMMARY: This paper presents a model that is developed to optimize the selection and operation of energy systems in commercial buildings based on their environmental performance. The model can be used for decision support regarding infrastructure in both design and operation of building energy systems. The approach is composed of energy simulation to generate building’s energy demand, life cycle assessment (LCA) to model different energy systems, and optimization model to optimize the selection and operation of these energy systems. The energy systems that are discussed in this paper are cogeneration systems, average electric grid, gas boilers, and absorption and electric chillers. The performance criteria presented in this paper are primary energy consumption (PEC) and tropospheric ozone precursor potential (TOPP).

Thermionic-cogeneration-burner assessment study. Second quarterly technical progress report, January-March 1983  

DOE Green Energy (OSTI)

The performance analysis work continued with the completion of the programming of the mathematical model and with the start of a series of parametric analyses. Initial studies predict that approximately 25 to 30% of the heat contained in the flue gas can be passed through the thermionic converters (TEC) and then be converted at 12 to 15% efficiency into electrical power. This results in up to 17 kWe per 1 million Btu/h burner firing rate. This is a 4 to 10 percent energy saving over power produced at the utility. The thermal burner design and construction have been completed, as well as initial testing on the furnace and preheat systems. The following industries are still considered viable options for use of the thermionic cogeneration burner: chlor-alkali, alumina-aluminum, copper refining, steel and gray iron, industries using resistance heating, electrolytic industries and electrochemical industries. Information gathered on these industries is presented.

Impacts of time-of-use rates on the optimal sizing and operation of cogeneration systems  

SciTech Connect

For customers with a cogeneration system (CGS), a mixed-integer programming and nonlinear programming model is used to examine effects of time-of-use (TOU) rates on the optimal operation of the constituent equipment as well as the optimal sizing. Three customers are selected for case studies: a hotel, a hospital, and an office building. Effects of an on-peak/off-peak energy charge ratio on purchased power share in the total electricity demand are saturated at the ratio of 5. As the energy charge ratio is raised, cheaper off-peak power substitutes for city gas and the operating cost decreases. The responses of the hotel and the hospital are similar. The simulation results included in this paper indicate that properly designed TOU rates can provide commercial customers an incentive to operate a CGS with an appropriate mix of the self-generation and commercial power.

A major cogeneration system goes in at JFK International Airport. Low-visibility privatization in a high-impact environment  

Science Conference Proceedings (OSTI)

This article describes the first major privatization effort to be completed at John F. Kennedy International Airport. The airport owner and operator, the Port Authority of New York and New Jersey, decided to seek private sector involvement in a capital-intensive project to expand and upgrade the airport`s heating and air conditioning facilities and construct a new cogeneration plant. Kennedy International Airport Cogeneration (KIAC) Partners, a partnership between Gas Energy Incorporated of New York and Community Energy Alternatives of New Jersey, was selected to develop an energy center to supply electricity and hot and chilled water to meet the airport`s growing energy demand. Construction of a 110 MW cogeneration plant, 7,000 tons of chilled water equipment, and 30,000 feet of hot water delivery piping started immediately. JFK Airport`s critical international position called for this substantial project to be developed almost invisibly; no interruption in heating and air conditioning service and no interference in the airport`s active operations could be tolerated. Commercial operation was achieved in February 1995.

Optimizing hourly hydro operations at the Salt Lake City Area integrated projects  

DOE Green Energy (OSTI)

The Salt Lake City Area (SLCA) office of the Western Area Power Administration (Western) is responsible for marketing the capacity and energy generated by the Colorado Storage, Collbran, and Rio Grande hydropower projects. These federal resources are collectively called the Salt Lake City Area Integrated Projects (SLCA/IP). In recent years, stringent operational limitations have been placed on several of these hydropower plants including the Glen Canyon Dam, which accounts for approximately 80% of the SLCA/IP resources. Operational limitations on SLCA/IP hydropower plants continue to evolve as a result of decisions currently being made in the Glen Canyon Dam Environmental Impact Statement (EIS) and the Power Marketing EIS. To analyze a broad range of issues associated with many possible future operational restrictions, Argonne National Laboratory (ANL), with technical assistance from Western has developed the Hydro LP (Linear Program) Model. This model simulates hourly operations at SLCA/IP hydropower plants for weekly periods with the objective of maximizing Western`s net revenues. The model considers hydropower operations for the purpose of serving SLCA firm loads, loads for special projects, Inland Power Pool (IPP) spinning reserve requirements, and Western`s purchasing programs. The model estimates hourly SLCA/IP generation and spot market activities. For this paper, hourly SLCA/IP hydropower plant generation is simulated under three operational scenarios and three hydropower conditions. For each scenario an estimate of Western`s net revenue is computed.

A desiccant/steam-injected gas-turbine industrial cogeneration system  

SciTech Connect

An integrated desiccant/steam-injected gas-turbine system was evaluated as an industrial cogenerator for the production of electricity and dry, heated air for product drying applications. The desiccant can be regenerated using the heated, compressed air leaving the compressor. The wet stream leaves the regenerator at a lower temperature than when it entered the desiccant regenerator, but with little loss of energy. The wet stream returns to the combustion chamber of the gas-turbine system after preheating by exchanging heat with the turbine exhaust strewn. Therefore, the desiccant is regenerated virtually energy-free. In the proposed system, the moisture-laden air exiting the desiccant is introduced into the combustion chamber of the gas-turbine power system. This paper discusses various possible design configurations, the impact of increased moisture content on the combustion process, the pressure drop across the desiccant regenerator, and the impact of these factors on the overall performance of the integrated system. A preliminary economic analysis including estimated potential energy savings when the system is used in several drying applications, and equipment and operating costs are also presented.

Model of penetration of coal boilers and cogeneration in the paper industry  

SciTech Connect

A model has been developed to forecast the penetration of coal boilers and cogeneration of electricity in the paper industry. Given the demand for energy services (process steam and electricity) by the paper industry, the Penetration Model forecasts the demand for purchased fuel and electricity. The model splits the demand for energy service between energy carriers (coal, fuel oil/natural gas, bark, and spent liquor) on the basis of the installed capacity of 16 types of boilers (combinations of four types of energy carriers and four types of throttle conditions). Investment in new boilers is allocated by an empirical distribution function among the 16 types of boilers on the basis of life cycle cost. In the short run (5 years), the Penetration Model has a small price response. The model has a large price response in the long run (30 years). For constant fuel prices, the model forecasts a 19-percent share for coal and a 65-percent share for residual oil in the year 2000. If the real price of oil and gas doubles by the year 2000, the model forecasts a 68-percent share for coal and a 26-percent share for residual oil.

Feasibility study: fuel cell cogeneration in a water pollution control facility. Final report  

DOE Green Energy (OSTI)

A conceptual design study was conducted to investigate the technical and economic feasibility of a cogeneration fuel cell power plant operating in a large water pollution control facility. The fuel cell power plant would use methane-rich digester gas from the water pollution control facility as a fuel feedstock to provide electrical and thermal energy. Several design configurations were evaluated. These configurations were comprised of combinations of options for locating the fuel cell power plant at the site, electrically connecting it with the water pollution control facility, using the rejected power plant heat, supplying fuel to the power plant, and for ownership and operation. A configuration was selected which met institutional/regulatory constraints and provided a net cost savings to the industry and the electric utility. This volume of the report contains the appendices: (A) abbreviations and definitions, glossary; (B) 4.5 MWe utility demonstrator power plant study information; (C) rejected heat utilization; (D) availability; (E) conceptual design specifications; (F) details of the economic analysis; (G) detailed description of the selected configuration; and (H) fuel cell power plant penetration analysis.

Development of a coal-fired gas turbine cogeneration system: Status report  

SciTech Connect

The Allison Advanced Coal-Fueled Turbine Program is now in the sixth year of a development effort that has led to a POC engine demonstration test on a Coal-Water-Slurry (CWS) fuel. Earlier forecasts by CWS suppliers that suitable CWS fuels would be commercially available at an economic price have not been realized. A program replan has, therefore, been executed that incorporates the use of readily available dry pulverized coal. To support this program, technology issues relating to combustor performance and emission control, hot gas cleanup, and turbine deposition, erosion and corrosion (DEC) have been addressed. In addition, system assessment studies have been performed to evaluate the commercial prospects for small (<8 MWe) coal-fired industrial cogeneration systems and the application of the rich-quench-lean (RQL) coal-combustion technology to larger (> 100 MWe) utility-sized gas turbines. These results are reported by Wenglarz (1992). Combustor and engine tests on dry coal are now planned in preparation for a commercial demonstration that will follow the completion of this program.

EARLY ENTRANCE CO-PRODUCTION PLANT - DECENTRALIZED GASIFICATION COGENERATION TRANSPORTATION FUELS AND STEAM FROM AVAILABLE FEEDSTOCKS  

SciTech Connect

Waste Processors Management, Inc. (WMPI), along with its subcontractors Texaco Power & Gasification (now ChevronTexaco), SASOL Technology Ltd., and Nexant Inc. entered into a Cooperative Agreement DE-FC26-00NT40693 with the U. S. Department of Energy (DOE), National Energy Technology Laboratory (NETL) to assess the technoeconomic viability of building an Early Entrance Co-Production Plant (EECP) in the United States to produce ultra clean Fischer-Tropsch (FT) transportation fuels with either power or steam as the major co-product. The EECP design includes recovery and gasification of low-cost coal waste (culm) from physical coal cleaning operations and will assess blends of the culm with coal or petroleum coke. The project has three phases. Phase I is the concept definition and engineering feasibility study to identify areas of technical, environmental and financial risk. Phase II is an experimental testing program designed to validate the coal waste mixture gasification performance. Phase III updates the original EECP design based on results from Phase II, to prepare a preliminary engineering design package and financial plan for obtaining private funding to build a 5,000 barrel per day (BPD) coal gasification/liquefaction plant next to an existing co-generation plant in Gilberton, Schuylkill County, Pennsylvania. The current report covers the period performance from July 1, 2002 through September 30, 2002.

Advanced coal-fueled industrial cogeneration gas turbine system: Hot End Simulation Rig  

DOE Green Energy (OSTI)

This Hot End Simulation Rig (HESR) was an integral part of the overall Solar/METC program chartered to prove the technical, economic, an environmental feasibility of a coal-fueled gas turbine, for cogeneration applications. The program was to culminate in a test of a Solar Centaur Type H engine system operated on coal slurry fuel throughput the engine design operating range. This particular activity was designed to verify the performance of the Centaur Type H engine hot section materials in a coal-fired environment varying the amounts of alkali, ash, and sulfur in the coal to assess the material corrosion. Success in the program was dependent upon the satisfactory resolution of several key issues. Included was the control of hot end corrosion and erosion, necessary to ensure adequate operating life. The Hot End Simulation Rig addressed this important issue by exposing currently used hot section turbine alloys, alternate alloys, and commercially available advanced protective coating systems to a representative coal-fueled environment at turbine inlet temperatures typical of Solar`s Centaur Type H. Turbine hot end components which would experience material degradation include the transition duct from the combustor outlet to the turbine inlet, the shroud, nozzles, and blades. A ceramic candle filter vessel was included in the system as the particulate removal device for the HESR. In addition to turbine material testing, the candle material was exposed and evaluated. Long-term testing was intended to sufficiently characterize the performance of these materials for the turbine.

High-temperature gas-cooled reactor steam cycle/cogeneration: lead project strategy plan  

SciTech Connect

The strategy, contained herein, for developing the HTGR system and introducing it into the energy marketplace is based on using the most developed technology path to establish a HTGR-Steam Cycle/Cogeneration (SC/C) Lead Project. Given the status of the HTGR-SC/C technology, a Lead Plant could be completed and operational by the mid 1990s. While there is remaining design and technology development that must be accomplished to fulfill technical and licensing requirements for a Lead Project commitment, the major barriers to the realization a HTGR-SC/C Lead Project are institutional in nature, e.g. budget priorities and constraints, cost/risk sharing between the public and private sector, Project organization and management, and Project financing. These problems are further complicated by the overall pervading issues of economic and regulatory instability that presently confront the utility and nuclear industries. This document addresses the major institutional issues associated with the HTGR-SC/C Lead Project and provides a starting point for discussions between prospective Lead Project participants toward the realization of such a Project.
