"Overview: The article addresses the growing trend in outsourcing boiler equipment, installation, operation, maintenance and ownership by large corporations, colleges and universities. Issues: To remain competitive and provide for growth, corporations and not-for-profit (NFP) organizations have changed the way they look at their energy systems: They are only allocating capital to ""core"" assets. In most cases, thennal, electric and air energy systems are not considered ""core"" assets resulting in the need to find ""other"" solutions to providing the needed energy. Reduced staffing has resulted in fewer experienced and knowledgeable boiler operating and maintenance personnel. Fluctuating energy costs make it difficult to accurately plan and budget. Constantly changing emissions standards and regulations add operational cost burdens. Objective: Find a solution to these pressures that does not require capital investment."

Annual fuel usage charts for oil-fired boilers. [Building space heating and hot water supplies  

SciTech Connect

On the basis of laboratory-determined boiler efficiency data, one may calculate the annual fuel usage (AFU) for any oil-fired boiler, serving a structure of a given design heat load, for any specified hourly weather pattern. Further, where data are available regarding the energy recapture rates of the strucutre due to direct gain solar energy (windows), lighting, cooking, electrical appliances, metabolic processes, etc., the annual fuel usage savings due to such (re) capture are straightforwardly determinable. Employing the Brookhaven National Laboratory annual fuel usage formulation, along with efficiency data determined in the BNL Boiler Laboratory, computer-drawn annual fuel usage charts can be generated for any selected boiler for a wide range of operating conditions. For two selected boilers operating in any one of the hour-by-hour weather patterns which characterize each of six cities over a wide range of firing rates, domestic hot water consumption rates, design heat loads, and energy (re) capture rates, annual fuel usages are determined and graphically presented. Figures 1 to 98, inclusive, relate to installations for which energy recapture rates are taken to be zero. Figures 97 to 130, inclusive, apply to a range of cases for which energy recapture rates are nonzero and determinable. In all cases, simple, direct and reliable annual fuel usage values can be determined by use of charts and methods such as those illustrated.

Effect of insulation location on initial transient thermal response of building walls  

E-Print Network (OSTI)

ABSTRACT: The effect of insulation location on the heat transfer characteristics of building wall elements under initial transient conditions is studied. Thermal performance with an insulation layer placed on the inside of a wall is compared to that when the insulation layer is placed on the outside. The investigation is carried out for the climatic conditions of Riyadh, Saudi Arabia, during representative days for July and January using a finite-volume implicit procedure. The initial temperature distribution across the wall is assumed to be uniform and equal to the daily mean external air temperature. The numerical model is validated against a semi-analytic solution developed for a simple test case. The results of model application under the present conditions show that placing the insulation on the inside gives an instantaneous load that is about 20 % of the value for outside insulation during the first few hours in the initial transient process. Besides, the duration of the transient process which leads to steady periodic state, and thus, the period of thermal discomfort due to radiation exchange is much shorter for the inside insulation. The average heat transmission over the first 24 hours

Assessment of the Energy Rating of Insulated Wall Assemblies - A Step Towards Building Energy Labeling  

E-Print Network (OSTI)

Considerable efforts are recently focusing on energy labeling of components and systems in buildings. In Canada, the energy rating of windows was established, which provides a protocol to rate different types of windows with respect to their energy performance. It takes into account the interaction between: solar heat gain, heat loss due to air leakage and due to the thermal properties of the entire window assembly. A major research project, jointly sponsored by NRC-IRC and the polyurethane spray foam industry, was established to assess the thermal and air leakage performance of insulated walls with the focus on developing an energy rating procedure for insulated wall assemblies. This paper is one in a series of publications to present partial results of this project. Experimental data and computer simulation comparison of a set of wall specimens are presented together with a summary of the proposed procedure for the determination of the energy rating of insulated walls (WER).

The Analysis of Dynamic Thermal Performance of Insulated Wall and Building Cooling Energy Consumption in Guangzhou  

E-Print Network (OSTI)

The summer in Guangzhou, China, is hot and long. Heat proofing is very important for the energy efficiency of buildings and improvement of the indoor thermal environment. The residential buildings in the southern region are cooled by air conditioning mainly with the increase of the live level. This study investigates the influence of the thermal dynamic performance on the yearly cooling load and yearly maximum cooling demand in typical residential flats by employing KVALUE and DeST. The simulation predictions indicate that reductions in the cooling load and maximum cooling demand are obtained when the insulation is added in the wall, but the potential of energy saving is quite limited when the wall only is insulated.

Energy and global warming impacts of CFC alternative technologies for foam building insulations  

Science Conference Proceedings (OSTI)

Chlorofluorocarbons (CFCS) have been used as blowing agents in foam insulation, as the working fluids in cooling and refrigeration equipment, and as solvents in general and precision cleaning applications since their introduction in the 1930s. The number of applications and volumes of CFCs used grew at a tremendous pace during the 1960s and 1970s, but in the mid-1980s it was confirmed that these extremely useful chemicals contribute to the destruction of stratospheric zone and that they are the primary cause of the CFCs have also been found to be second only to carbon dioxide as a factor causing increased greenhouse warming. These chemicals are being phased out of use rapidly to protect the ozone layer and it is very important that the replacements for CFCs do not result in a net increase in global warming by introducing less efficient processes that lead to higher energy use and increased carbon dioxide emissions. A study was conducted to identify those alternative chemicals and technologies that could replace CFCs in energy related applications before the year 2000, and to assess the total potential impact of those alternatives on global warming. The analysis for this project included an estimate of the direct effects from the release of blowing agents, refrigerants, and solvents into the atmosphere and the indirect effects of carbon dioxide emissions resulting from energy use for commercial and residential building insulation, household and commercial refrigeration, building and automobile air conditioning, and general metal and electronics solvent cleaning. This paper focuses on those aspects of the study relevant to building insulation. In general the hydrofluorocarbon (HFC) and hydrochlorofluorocarbon alternatives for CFCs lead to large and sometimes dramatic reductions in total equivalent warming impact, lifetime equivalent C0{sub 2} emissions (TEWI). Most of the reductions result from decreased direct effects without significant changes in energy use.

The number of applications and volumes of CFCs used grew at a tremendous pace during the 1960s and 1970s, but in the mid-1980s it was confirmed that these extremely useful chemicals contribute to the destruction of stratospheric zone and that they are the primary cause of the CFCs have also been found to be second only to carbon dioxide as a factor causing increased greenhouse warming. These chemicals are being phased out of use rapidly to protect the ozone layer and it is very important that the replacements for CFCs do not result in a net increase in global warming by introducing less efficient processes that lead to higher energy use and increased carbon dioxide emissions. A study was conducted to identify those alternative chemicals and technologies that could replace CFCs in energy related applications before the year 2000, and to assess the total potential impact of those alternatives on global warming. The analysis for this project included an estimate of the direct effects from the release of blowing agents, refrigerants, and solvents into the atmosphere and the indirect effects of carbon dioxide emissions resulting from energy use for commercial and residential building insulation, household and commercial refrigeration, building and automobile air conditioning, and general metal and electronics solvent cleaning. This paper focuses on those aspects of the study relevant to building insulation. In general the hydrofluorocarbon (HFC) and hydrochlorofluorocarbon alternatives for CFCs lead to large and sometimes dramatic reductions in total equivalent warming impact, lifetime equivalent C0{sub 2} emissions (TEWI). Most of the reductions result from decreased direct effects without significant changes in energy use.

Corrosiveness of wet residential building thermal insulation---Mechanisms and evaluation of electrochemical methods for assessing corrosion behavior  

SciTech Connect

An evaluation has been made of the corrosiveness of selected wet residential building thermal insulation materials in contact with low carbon steel. Investigations were conducted both in wet insulations and in filtered leachates from insulations derived from thirteen cellulosic, three mineral fiber and four foam products. Potentiodynamic polarization measurements are reported from which the overall corrosion response was assessed and then the techniques of Tafel and polarization resistance analysis applied to estimate corrosion rates. Corrosion rates were also estimated electrochemically using a direct reading instrument which performs the rate calculation based on the polarization resistance principle. Direct determinations of corrosion rate were based on weight loss measurements.

A review of vacuum insulation research and development in the Building Materials Group of the Oak Ridge National Laboratory  

SciTech Connect

This report is a summary of the development work on flat-vacuum insulation performed by the Building Materials Group (BMG) in the Metals and Ceramics Division of the Oak Ridge National Laboratory (ORNL) during the last two years. A historical review of the technology of vacuum insulation is presented, and the role that ORNL played in this development is documented. The ORNL work in vacuum insulation has been concentrated in Powder-filled Evacuated Panels (PEPs) that have a thermal resistivity over 2.5 times that of insulating foams and seven times that of many batt-type insulations, such as fiberglass. Experimental results of substituting PEPs for chlorofluorocarbon (CFC) foal insulation in Igloo Corporation ice coolers are summarized. This work demonstrated that one-dimensional (1D) heat flow models overestimated the increase in thermal insulation of a foam/PEP-composite insulation, but three-dimensional (3D) models provided by a finite-difference, heat-transfer code (HEATING-7) accurately predicted the resistance of the composites. Edges and corners of the ice coolers were shown to cause the errors in the 1D models as well as shunting of the heat through the foam and around the PEPs. The area of coverage of a PEP in a foam/PEP composite is established as an important parameter in maximizing the resistance of such composites. 50 refs., 27 figs,. 22 tabs.

A procedure for analyzing energy and global warming impacts of foam insulation in U.S. commercial buildings  

SciTech Connect

The objective of this paper is to develop a procedure for evaluating the energy and global warming impacts of alternative insulation technologies for US commercial building applications. The analysis is focused on the sum of the direct contribution of greenhouse gas emissions from a system and the indirect contribution of the carbon dioxide emission resulting from the energy required to operate the system over its expected lifetime. In this paper, parametric analysis was used to calculate building related CO{sub 2} emission in two US locations. A retail mail building has been used as a model building for this analysis. For the analyzed building, minimal R-values of insulation are estimated using ASHRAE 90.1 requirements.

The Revision of the UK Pipe Insulation Standard: - Its Likely Effect on Building Energy Efficiency and the Uptake of Highly Efficient Insulation Materials  

E-Print Network (OSTI)

The UK Government has set an ambitious target of a 20% reduction in CO2 emissions by 2010 based on a 1990 baseline. Since buildings account for over 40% of current CO2 emissions, the revision of building and building services insulation standards has been a high priority. The previous UK pipe insulation standard (BS 5422 - 1990) was based on an economic thickness methodology that resulted in thickness requirements for different materials of unequal energy saving value. The 2001 revision (BS 5422 - 2001) not only addresses this imbalance by defining environmental thicknesses that deliver equivalent energy savings but also increases the potential to reduce CO2 emissions by up to 5 million tonnes per annum. To stimulate this potential, the UK Government has introduced a tax incentive under the existing Capital Allowances scheme to promote the widespread adoption of the new standard in both new build and, more importantly, in renovation projects. Just as importantly, the new standard highlights the true cost-effectiveness of highly efficient insulation materials such as phenolic foam. Phenolic foam had already gained more than a 15% market share in the UK pipe insulation market prior to the recent changes to the standard on the basis of its excellent thermal resistance and fire properties. However, previous economic thickness models had promoted the use of less efficient materials with a poorer level of energy saving being the result. With this loophole now closed, the phenolic foam industry believes that its product will receive the acclamation that it deserves - while helping the UK Government to meet its own CO2 targets.

Theoretical and Experimental Thermal Performance Analysis of Building Shell Components Containing Blown Fiber Glass Insulation Enhanced with Phase Change Material (PCM)  

Science Conference Proceedings (OSTI)

Different types of Phase Change Materials (PCMs) have been tested as dynamic components in buildings during the last 4 decades. Most historical studies have found that PCMs enhance building energy performance. Some PCM-enhanced building materials, like PCM-gypsum boards or PCM-impregnated concretes have already found their limited applications in different countries. Today, continued improvements in building envelope technologies suggest that throughout Southern and Central US climates, residences may soon be routinely constructed with PCM in order to maximize insulation effectiveness and maintain low heating and cooling loads. The proposed paper presents experimental and numerical results from thermal performance studies. These studies focus on blown fiber glass insulation modified with a novel spray-applied microencapsulated PCM. Experimental results are reported for both laboratory-scale and full-size building elements tested in the field. In order to confirm theoretical predictions, PCM enhanced fiber glass insulation was evaluated in a guarded hot box facility to demonstrate heat flow reductions when one side of a test wall is subjected to a temperature increase. The laboratory work showed reductions in heat flow of 30% due to the presence of approximately 20 wt % PCM in the insulation. Field testing of residential attics insulated with blown fiber glass and PCM was completed in Oak Ridge, Tennessee. Experimental work was followed by detailed whole building EnergyPlus simulations in order to generate energy performance data for different US climates. In addition, a series of numerical simulations and field experiments demonstrated a potential for application of a novel PCM fiber glass insulation as enabling technology to be utilized during the attic thermal renovations.

Development of a Process to Build Polyimide Insulated Magnets For Operation at 350C  

SciTech Connect

An extensive R&D program has been conducted that has confirmed the feasibility of designing and fabricating copper alloy magnets that can successfully operate at temperatures as high as 350C. The process, originally developed for the possibility of manufacturing in-vessel resonant magnetic field perturbation (RMP) coils for JET, has been optimized for insulated magnet (and, potentially, other high temperature component) applications. One of the benefits of high temperature operation is that active cooling may no longer be required, greatly simplifying magnet/component design. These elevated temperatures are beyond the safe operating limits of conventional OFHC copper and the epoxies that bond and insulate the turns of typical magnets. This would necessitate the use an alternative copper alloy conductor such as C18150 (CuCrZr). Coil manufacture with polyimide is very similar to conventional epoxy bonded coils. Conductors would be dry wound then impregnated with polyimide of low enough viscosity to permit saturation, then cured; similar to the vacuum pressure impregnation process used for conventional epoxy bonded coils. Representative polyimide insulated coils were mechanically tested at both room temperature and 350C. Mechanical tests included turn-to-turn shear bond strength and overall polyimide adhesion strength, as well as the flexural strength of a 48-turn polyimide-bonded coil bundle. This paper will detail the results of the testing program on coil samples. These results demonstrate mechanical properties as good, or better than epoxy bonded magnets, even at 350C.

A guidebook for insulated low-slope roof systems. IEA Annex 19, Low-slope roof systems: International Energy Agency Energy Conservation in Buildings and Community Systems Programme  

SciTech Connect

Low-slope roof systems are common on commercial and industrial buildings and, to a lesser extent, on residential buildings. Although insulating materials have nearly always been a component of low-slope roofs, the amount of insulation used has increased in the past two decades because of escalation of heating and cooling costs and increased awareness of the need for energy conservation. As the amount of insulation has increased, the demand has intensified for design, installation, and maintenance information specifically for well-insulated roofs. Existing practices for design, installation, and maintenance of insulated roofs have evolved from experience. Typically, these practices feature compromises due to the different properties of materials making up a given roof system. Therefore, they should be examined from time to time to ensure that they are appropriate as new materials continue to enter the market and as the data base on existing systems expands. A primary purpose of this International Energy Agency (IEA) study is to assess current roofing insulation practices in the context of an accumulating data base on performance.

NATIONAL RESEARCH COUNCIL OF CANADA DIVISION OF BUILDING RESEARCH PERFORMANCE OF INSULATIONS LOCATED ABOVE AN IMPERMEABLE MEMBRANE IN A FLAT ROOF SYSTEM  

E-Print Network (OSTI)

The impermeable membrane of a flat roof can be protected from solar radiation, the effects of extreme temperature variation, and from traffic damage by placing it beneath the roof insulation. This provides the membrane with a better chance of performing its function of protecting the building from the entry of moisture. Now, however, the insulation is exposed to the weather and may lose its thermal insulating properties by becoming wet. Using experimental facilities which permit exposure of materials to outdoor conditions, several insulations- both porous and closed cell- were incorporated into a roof system of this type. Moisture contents and thermal conductances were measured periodically over a span of about two years. The results are reported here. This is being followed by work involving similar measurements with other design arrangements.

Joint China-United States Report for Year 1 Insulation Materials and Systems Project Area Clean Energy Research Center Building Energy Efficiency (CERC-BEE)  

Science Conference Proceedings (OSTI)

In November of 2009, the presidents of China and the U.S. announced the establishment of the Clean Energy Research Center (CERC). This broad research effort is co-funded by both countries and involves a large number of research centers and universities in both countries. One part of this program is focused on improving the energy efficiency of buildings. One portion of the CERC-BEE was focused on building insulation systems. The research objective of this effort was to Identify and investigate candidate high performance fire resistant building insulation technologies that meet the goal of building code compliance for exterior wall applications in green buildings in multiple climate zones. A Joint Work Plan was established between researchers at the China Academy of Building Research and Oak Ridge National Laboratory. Efforts in the first year under this plan focused on information gathering. The objective of this research program is to reduce building energy use in China via improved building insulation technology. In cold regions in China, residents often use inefficient heating systems to provide a minimal comfort level within inefficient buildings. In warmer regions, air conditioning has not been commonly used. As living standards rise, energy consumption in these regions will increase dramatically unless significant improvements are made in building energy performance. Previous efforts that defined the current state of the built environment in China and in the U.S. will be used in this research. In countries around the world, building improvements have typically followed the implementation of more stringent building codes. There have been several changes in building codes in both the U.S. and China within the last few years. New U.S. building codes have increased the amount of wall insulation required in new buildings. New government statements from multiple agencies in China have recently changed the requirements for buildings in terms of energy efficiency and fire safety. A related issue is the degree to which new standards are adopted and enforced. In the U.S., standards are developed using a consensus process, and local government agencies are free to implement these standards or to ignore them. For example, some U.S. states are still using 2003 versions of the building efficiency standards. There is also a great variation in the degree to which the locally adopted standards are enforced in different U.S. cities and states. With a more central process in China, these issues are different, but possible impacts of variable enforcement efficacy may also exist. Therefore, current building codes in China will be compared to the current state of building fire-safety and energy-efficiency codes in the U.S. and areas for possible improvements in both countries will be explored. In particular, the focus of the applications in China will be on green buildings. The terminology of 'green buildings' has different meanings to different audiences. The U.S. research is interested in both new, green buildings, and on retrofitting existing inefficient buildings. An initial effort will be made to clarify the scope of the pertinent wall insulation systems for these applications.

An Experimental Study of the Performance of PCM-Enhanced Cellulose Insulation Used in Residential Building Walls Exposed to Full Weather Conditions  

E-Print Network (OSTI)

Air conditioning energy consumption in summer represents a major concern in many areas with hot and humid climates. When incorporated into the walls of light-weight residential buildings, phase change materials (PCMs) can increase the effective thermal mass of the walls and shift part of the space cooling loads to off-peak hours. The thermal properties of pure phase change materials (PCMs) and those of the mixtures of PCMs with cellulose insulation were studied via differential scanning calorimeter (DSC) tests and mass change tests. To directly prove the concept that PCM-enhanced insulation can reduce the peak heat flux across walls as well as its potential to shift part of the space cooling loads to a later time of the day, the performance of PCM-enhanced cellulose insulation was studied using two small-scale testing houses exposed to full weather conditions during the summer seasons. The testing houses were air conditioned and independently metered. Both houses had identical thermal responses prior to any retrofits. Before the tests, the PCM enhanced insulation was blown into the wall cavities in one test house while plain cellulose insulation was installed in the other house for comparison purposes. Hourly heat fluxes and daily heat flow data for four walls are presented. Based on the results, important recommendations are provided for the optimal use of PCMs in insulation systems.

This project examines the implementation of an exterior insulation and over-clad strategy for brick masonry buildings in Chicago. The strategy was implemented at a free-standing two story two-family dwelling and a larger free-standing multifamily building. The test homes selected for this research represent predominant housing types for the Chicago area. High heating energy use typical in these buildings threaten housing affordability. Uninsulated mass masonry wall assemblies also have a strongly detrimental impact on comfort. Significant changes to the performance of masonry wall assemblies is generally beyond the reach of typical weatherization (Wx) program resources. The Community and Economic Development Association of Cook County, Inc. (CEDA) has secured a Sustainable Energy Resources for Consumers (SERC) innovation grant sponsored by the United States Department of Energy (DOE). This grant provides CEDA the opportunity to pursue a pilot implementation of innovative approaches to retrofit in masonry wall enclosures. The exterior insulation and over-clad strategy implemented through this project was designed to allow implementation by contractors active in CEDA weatherization programs and using materials and methods familiar to these contractors. The retrofit measures are evaluated in terms of feasibility, cost and performance. Through observations of the strategies implemented, the research described in this report identifies measures critical to performance as well as conditions for wider adoption. The research also identifies common factors that must be considered in determining whether the exterior insulation and over-clad strategy is appropriate for the building.

Steam Boiler Control Specification Problem:  

E-Print Network (OSTI)

Our solution to the specification problem in the specification language TLA+ is based on a model of operation where several components proceed synchronously. Our first specification concerns a simplified controller and abstracts from many details given in the informal problem description. We successively add modules to build a model of the state of the steam boiler, detect failures, and model message transmission. We give a more detailed controller specification and prove that it refines the abstract controller. We also address the relationship between the physical state of the steam boiler and the model maintained by the controller and discuss the reliability of failure detection. Finally, we discuss the implementability of our specification.

Aerogel Insulation Aerogel Insulation New and Underutilized Technology: Aerogel Insulation October 8, 2013 - 2:54pm Addthis The following information outlines key deployment considerations for aerogel insulation within the Federal sector. Benefits Aerogel insulation products displace current insulation materials. The thermal conductivity of aerogel is very low, allowing it to retain insulation properties at a much thinner thickness. Application Aerogel insulation is appropriate for deployment across piping, ducts, and within most building categories. It should be considered in building design, construction, or major renovation. Key Factors for Deployment Aerogel insulations are more expensive than typical insulations. However, they are ideal for special applications, such as translucent wall panels.

BOILER PERF MODEL  

Science Conference Proceedings (OSTI)

The BOILER PERFORMANCE MODEL is a package of eleven programs for predicting the heat transfer performance of fossil-fired utility boilers. The programs can model a wide variety of boiler designs, provide boiler performance estimates for coal, oil or gaseous fuels, determine the influence of slagging and fouling characteristics on boiler performance, and calculate performance factors for tradeoff analyses comparing boilers and fuels. Given a set of target operating conditions, the programs can estimate control settings, gas and steam operating profiles through the boiler, overall boiler efficiency, and fuel consumption. The programs are broken into three categories: data, calculation, and reports with a central processor program acting as the link allowing the user to access any of the data or calculation programs and easily move between programs. The calculations are divided among the following five programs: heat duty calculation, combustion calculation, furnace performance calculation, convection pass performance calculation, and air heater performance calculation. The programs can model subcritical or supercritical boilers, most configurations of convective passes including boilers that achieve final reheat steam temperature control by split back pass, boilers with as many as two reheat circuits and/or multiple attemperator stations in series, and boilers with or without economizers and/or air heaters. Either regenerative or tubular air heaters are supported. For wall-fired or tangentially-fired furnaces, the furnace performance program predicts the temperature of the flue gases leaving the furnace. It accounts for variations in excess air, gas recirculation, burner tilt, wall temperature, and wall cleanliness. For boilers having radiant panels or platens above the furnace, the convective pass program uses the results of the combustion chamber calculation to estimate the gas temperature entering the convective pass.

Boiler Tube Internal Oxide Scale Thickness Measurement: Best Practices  

Science Conference Proceedings (OSTI)

Long-term high-temperature exposure of reheater and superheater tubes in fossil-fired steam boilers results in the growth of iron oxide scale (magnetite) on the inner tube surface. This internal oxide layer on the water side of the tube acts as a thermal insulator, reducing heat transfer through the tube wall into the internal water vapor. Over time, this insulating effect limits heat transmission into the water vapor inside the tube, which, in turn, causes chronic overheating of the tube wall. The ...

Highly Insulating Window Technology  

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

Window Technology Window Technology Temperature differentials across a window, particularly with cold exterior environments in residential buildings, can lead to significant energy losses. Currently available low-emissivity coatings, gas-fills, and insulating frames provide significant energy savings over typical single or double glazed products. The EWC website provides information on how double glazed low-e gas-filled windows work as well as information on commercially available superwindows (three layer, multiple low-e coatings, high performance gas-fills). The next generation of highly insulating window systems will benefit from incremental improvements being made to current components (i.e. more insulating spacers and frame materials/designs, low-e coatings with improved performance properties). LBNL uses its experimental facilities and software tools to collaborate with window and glass industry representatives to better understand the impacts of new components on overall product performance.

Clean Firetube Boiler Waterside Heat Transfer Surfaces, Energy Tips: STEAM, Steam Tip Sheet #7 (Fact Sheet)  

SciTech Connect

A steam energy tip sheet for the Advanced Manufacturing Office (AMO). The prevention of scale formation in firetube boilers can result in substantial energy savings. Scale deposits occur when calcium, magnesium, and silica, commonly found in most water supplies, react to form a continuous layer of material on the waterside of the boiler heat exchange tubes. Scale creates a problem because it typically possesses a thermal conductivity, an order of magnitude less than the corresponding value for bare steel. Even thin layers of scale serve as an effective insulator and retard heat transfer. The result is overheating of boiler tube metal, tube failures, and loss of energy efficiency. Fuel consumption may increase by up to 5% in firetube boilers because of scale. The boilers steam production may be reduced if the firing rate cannot be increased to compensate for the decrease in combustion efficiency. Energy losses as a function of scale thickness and composition are given. Any scale in a boiler is undesirable. The best way to deal with scale is not to let it form in the first place. Prevent scale formation by: (1) Pretreating of boiler makeup water (using water softeners, demineralizers, and reverse osmosis to remove scale-forming minerals); (2) Injecting chemicals into the boiler feedwater; and (3) Adopting proper boiler blowdown practices.

Recovery Boiler Modeling  

E-Print Network (OSTI)

Preliminary computations of the cold flow in a simplified geometry of a recovery boiler are presented. The computations have been carried out using a new code containing multigrid methods and segmentation techniques. This approach is shown to provide good resolution of the complex flow near the air ports and greatly improve the convergence characteristics of the numerical procedure. The improved resolution enhances the predictive capabilities of the computations, and allows the assessment of the relative performance of different air delivery systems.

A Boiler Plant Energy Efficiency and Load Balancing Survey  

E-Print Network (OSTI)

Daily energy use data was used to perform an energy efficiency survey of a medium-sized university boiler plant. The physical plant operates centralized mechanical plants to provide both chilled water and steam for building conditioning. Steam is used for heating buildings and to operate a 4000-ton steam-driven chiller. There are five natural gas-fired steam boilers that have rated capacities ranging from 40,000 lb/hr to 100,000 lb/hr at an operating pressure of 125 psig. This paper discusses the operating characteristics of the boiler and potential energy efficiency improvements. Results from the study included that reducing excess air levels to recommended minimums would save over $15,000 per year.

Super Boiler 2nd Generation Technology for Watertube Boilers  

Science Conference Proceedings (OSTI)

This report describes Phase I of a proposed two phase project to develop and demonstrate an advanced industrial watertube boiler system with the capability of reaching 94% (HHV) fuel-to-steam efficiency and emissions below 2 ppmv NOx, 2 ppmv CO, and 1 ppmv VOC on natural gas fuel. The boiler design would have the capability to produce >1500 F, >1500 psig superheated steam, burn multiple fuels, and will be 50% smaller/lighter than currently available watertube boilers of similar capacity. This project is built upon the successful Super Boiler project at GTI. In that project that employed a unique two-staged intercooled combustion system and an innovative heat recovery system to reduce NOx to below 5 ppmv and demonstrated fuel-to-steam efficiency of 94% (HHV). This project was carried out under the leadership of GTI with project partners Cleaver-Brooks, Inc., Nebraska Boiler, a Division of Cleaver-Brooks, and Media and Process Technology Inc., and project advisors Georgia Institute of Technology, Alstom Power Inc., Pacific Northwest National Laboratory and Oak Ridge National Laboratory. Phase I of efforts focused on developing 2nd generation boiler concepts and performance modeling; incorporating multi-fuel (natural gas and oil) capabilities; assessing heat recovery, heat transfer and steam superheating approaches; and developing the overall conceptual engineering boiler design. Based on our analysis, the 2nd generation Industrial Watertube Boiler when developed and commercialized, could potentially save 265 trillion Btu and $1.6 billion in fuel costs across U.S. industry through increased efficiency. Its ultra-clean combustion could eliminate 57,000 tons of NOx, 460,000 tons of CO, and 8.8 million tons of CO2 annually from the atmosphere. Reduction in boiler size will bring cost-effective package boilers into a size range previously dominated by more expensive field-erected boilers, benefiting manufacturers and end users through lower capital costs.

Small boiler uses waste coal  

SciTech Connect

Burning coal waste in small boilers at low emissions poses considerable problem. While larger boiler suppliers have successfully installed designs in the 40 to 80 MW range for some years, the author has been developing small automated fluid bed boiler plants for 25 years that can be applied in the range of 10,000 to 140,000 lbs/hr of steam. Development has centered on the use of an internally circulating fluid bed (CFB) boiler, which will burn waste fuels of most types. The boiler is based on the traditional D-shaped watertable boiler, with a new type of combustion chamber that enables a three-to-one turndown to be achieved. The boilers have all the advantages of low emissions of the large fluid boilers while offering a much lower height incorporated into the package boiler concept. Recent tests with a waste coal that had a high nitrogen content of 1.45% demonstrated a NOx emission below the federal limit of 0.6 lbs/mm Btu. Thus a NOx reduction on the order of 85% can be demonstrate by combustion modification alone. Further reductions can be made by using a selective non-catalytic reduction (SNCR) system and sulfur absorption of up to 90% retention is possible. The article describes the operation of a 30,000 lbs/hr boiler at the Fayette Thermal LLC plant. Spinheat has installed three ICFB boilers at a nursing home and a prison, which has been tested on poor-grade anthracite and bituminous coal. 2 figs.

Environmental design using dynamic insulation  

SciTech Connect

In conventional airtight buildings, the architect has considerable freedom to decide how much the external environment will influence the internal heating, cooling, and ventilation loads. The services engineer provides the plant and equipment required to deal with these loads. This division of labor could lead to undesirable consequences in the case of dynamic insulation, a form of air permeable construction where bulk air flow through the building envelope may be used to either enhance or restrict the conductive heat and mass diffusion fluxes. Small changes in temperature (indoor and out) and wind speed and direction will influence the behavior of a dynamically insulated envelope since the internal and external environments are much more intimately coupled. Buildings employing dynamic insulation thus require good environmental design principles to be applied. The objective of this paper is to lay down rigorous principles that will form the basis of guidelines to architects and building services engineers on how to take account of the ever changing external environment when designing durable and comfortable buildings employing dynamic insulation.

Opportunities in EPA's Boiler Rules Opportunities in EPA's Boiler Rules On December 20, 2012, the US Environmental Protection Agency (EPA) finalized new regulations to control emissions of hazardous air pollutants (HAP) from commercial, industrial, and institutional boilers and process heaters. These new rules, known as the Boiler MACT (major sources) and Boiler Area Source Rule (smaller sources), will reduce the amount of HAPS such as mercury, heavy metals, and other toxics that enter the environment. Since emissions from boilers are linked to fuel consumption, energy efficiency is an important strategy for complying with the new Boiler rules. Who is affected? Most existing industrial, commercial and institutional (ICI) boilers will not be affected by the Boiler MACT. These unaffected boilers are mostly small natural gas-fired boilers.

Steam boiler control specification problem: A TLA solution  

E-Print Network (OSTI)

. Our solution to the specification problem in the specification language TLA+ is based on a model of operation where several components proceed synchronously. Our first specification concerns a simplified controller and abstracts from many details given in the informal problem description. We successively add modules to build a model of the state of the steam boiler, detect failures, and model message transmission. We give a more detailed controller specification and prove that it refines the abstract controller. We also address the relationship between the physical state of the steam boiler and the model maintained by the controller and discuss the reliability of failure detection. Finally, we discuss the implementability of our specification. 1 Introduction We propose a solution to the steam boiler control specification problem [AS] by means of a formal specification in the specification language TLA+, which is based on Lamport's Temporal Logic of Actions TLA [L94].

Impact of Thermally Insulated Floors  

E-Print Network (OSTI)

Presently in Kuwait the code of practice for energy conservation in the air conditioned buildings implemented by the Ministry of Electricity and Water (MEW) which has been in effect since 1983 has no consideration taken for thermally insulating the floors of residential and commercial buildings with unconditioned basements. As a part of a comprehensive research program conducted by the Building and Energy Technologies Department of Kuwait Institute for Scientific Research for revision of the code this paper analyzes the effect of using un-insulated floors on the peak cooling demand and energy consumption of a middle income residential private villa and a onebedroom multi-story apartment building in Kuwait. These floors typically separate air-conditioned spaces with ambient environment or un-conditioned spaces. This was done using the ESP-r, a building's energy simulation program, in conjunction with typical meteorological year for Kuwait. The study compared such typical floors with three types of insulated floors. It was found that using an R- 10 floors in multi-story apartment buildings greatly reduce both the peak cooling demand as well as the energy consumption by about 15%, whereas only minimal savings (about 4%) were detected in the case of the residential villas.

Computer Control of Boiler Operation  

E-Print Network (OSTI)

Rapidly rising energy costs present the opportunity for substantial cost savings through improved boiler combustion control. A process computer control system was installed at an Air Products & Chemicals facility in 1978. As a result the boiler efficiency has increased over 11%. The control system includes; air flow, fuel flow, pressure and drum level control. Air flow control is achieved through modulation of the F.D. fan inlet vanes. Demand for airflow is produced from a high signal selection of the steam pressure controller or the total fuel signal. The output of the oxygen controller is used to modify this airflow index by the desired air/fuel ratio. The air/fuel ratio is a polynomial function of the type of fuel used. In summary, the computer control system provides for; greater overall boiler stability, operation within tight air/gas limits, increased boiler efficiency, capability to burn multiple fuels, faster response to demand changes, and fewer shutdowns.

BOILER MATERIALS FOR ULTRASUPERCRITICAL COAL POWER PLANTS  

Science Conference Proceedings (OSTI)

The U.S. Department of Energy (DOE) and the Ohio Coal Development Office (OCDO) have recently initiated a project aimed at identifying, evaluating, and qualifying the materials needed for the construction of the critical components of coal-fired boilers capable of operating at much higher efficiencies than current generation of supercritical plants. This increased efficiency is expected to be achieved principally through the use of ultrasupercritical steam conditions (USC). The project goal initially was to assess/develop materials technology that will enable achieving turbine throttle steam conditions of 760 C (1400 F)/35 MPa (5000 psi), although this goal for the main steam temperature had to be revised down to 732 C (1350 F), based on a preliminary assessment of material capabilities. The project is intended to build further upon the alloy development and evaluation programs that have been carried out in Europe and Japan. Those programs have identified ferritic steels capable of meeting the strength requirements of USC plants up to approximately 620 C (1150 F) and nickel-based alloys suitable up to 700 C (1300 F). In this project, the maximum temperature capabilities of these and other available high-temperature alloys are being assessed to provide a basis for materials selection and application under a range of conditions prevailing in the boiler. This report provides a quarterly status report for the period of October 1 to December 30, 2003.

The project goal initially was to assess/develop materials technology that will enable achieving turbine throttle steam conditions of 760 C (1400 F)/35 MPa (5000 psi), although this goal for the main steam temperature had to be revised down to 732 C (1350 F), based on a preliminary assessment of material capabilities. The project is intended to build further upon the alloy development and evaluation programs that have been carried out in Europe and Japan. Those programs have identified ferritic steels capable of meeting the strength requirements of USC plants up to approximately 620 C (1150 F) and nickel-based alloys suitable up to 700 C (1300 F). In this project, the maximum temperature capabilities of these and other available high-temperature alloys are being assessed to provide a basis for materials selection and application under a range of conditions prevailing in the boiler. This report provides a quarterly status report for the period of July 1 to September 30, 2004.

Implementation of Boiler Best Practices  

E-Print Network (OSTI)

Boilers are an essential part of any industrial plant, and their efficient, economical operation can significantly affect the reliability and profitability of the entire plant. Best Practices for Boilers include tools to determine where a plant or corporation is with respect to boiler treatment, what needs to be done to make the plant (corporation) the "best of the best," and how to get there. When implemented, Best Practices provide a method to measure and track progress, and represent a benchmark for continuous improvement. Best Practices combine our global collective experience from the areas of research, consulting, sales and marketing, and involve not only recommendations and specifications, but also the rationale behind them for the application of the chosen treatment, monitoring, and instrumentation. Best practices provide energy savings, profitability improvement, reduction in total cost of operations, project management, optimized treatment choices, enhanced safety, system assessment processes and facilitated system improvements.

Membranes Improve Insulation Efficiency  

E-Print Network (OSTI)

It has been determined from extensive tests involving test models and home attics that loose fill and fiber batt insulation does not function as expected by the industry. The reason for this deficiency is current test methods do not accurately predict the magnitude of air infiltration into fiber insulation as used in home attics, radiant heat infiltration into the insulation during summer, or radiant heat loss through the insulation during winter conditions. The use of (1) moisture permeable membranes over the insulation, and (2) layered membranes between fiber batts to form closed cells in the insulation both dramatically improve the efficiency of the fiber insulation. The efficiency of this insulation will be improved to an even greater degree if these membranes reflect radiant heat as well as reduce convection air currents. Extensive tests have also been conducted which show that if moisture permeable membranes are used over fiber insulation, the moisture content of the insulation will be reduced.

Alternate Materials for Recovery Boiler Superheater Tubes  

SciTech Connect

The ever escalating demands for increased efficiency of all types of boilers would most sensibly be realized by an increase in the steam parameters of temperature and pressure. However, materials and corrosion limitations in the steam generating components, particularly the superheater tubes, present major obstacles to boiler designers in achieving systems that can operate under the more severe conditions. This paper will address the issues associated with superheater tube selection for many types of boilers; particularly chemical recovery boilers, but also addressing the similarities in issues for biomass and coal fired boilers. It will also review our recent study of materials for recovery boiler superheaters. Additional, more extensive studies, both laboratory and field, are needed to gain a better understanding of the variables that affect superheater tube corrosion and to better determine the best means to control this corrosion to ultimately permit operation of recovery boilers at higher temperatures and pressures.

Superheater Corrosion In Biomass Boilers: Today's Science and Technology  

DOE Green Energy (OSTI)

This report broadens a previous review of published literature on corrosion of recovery boiler superheater tube materials to consider the performance of candidate materials at temperatures near the deposit melting temperature in advanced boilers firing coal, wood-based fuels, and waste materials as well as in gas turbine environments. Discussions of corrosion mechanisms focus on the reactions in fly ash deposits and combustion gases that can give corrosive materials access to the surface of a superheater tube. Setting the steam temperature of a biomass boiler is a compromise between wasting fuel energy, risking pluggage that will shut the unit down, and creating conditions that will cause rapid corrosion on the superheater tubes and replacement expenses. The most important corrosive species in biomass superheater corrosion are chlorine compounds and the most corrosion resistant alloys are typically FeCrNi alloys containing 20-28% Cr. Although most of these materials contain many other additional additions, there is no coherent theory of the alloying required to resist the combination of high temperature salt deposits and flue gases that are found in biomass boiler superheaters that may cause degradation of superheater tubes. After depletion of chromium by chromate formation or chromic acid volatilization exceeds a critical amount, the protective scale gives way to a thick layer of Fe{sub 2}O{sub 3} over an unprotective (FeCrNi){sub 3}O{sub 4} spinel. This oxide is not protective and can be penetrated by chlorine species that cause further acceleration of the corrosion rate by a mechanism called active oxidation. Active oxidation, cited as the cause of most biomass superheater corrosion under chloride ash deposits, does not occur in the absence of these alkali salts when the chloride is present as HCl gas. Although a deposit is more corrosive at temperatures where it is molten than at temperatures where it is frozen, increasing superheater tube temperatures through the measured first melting point of fly ash deposits does not necessarily produce a step increase in corrosion rate. Corrosion rate typically accelerates at temperatures below the first melting temperature and mixed deposits may have a broad melting temperature range. Although the environment at a superheater tube surface is initially that of the ash deposits, this chemistry typically changes as the deposits mature. The corrosion rate is controlled by the environment and temperature at the tube surface, which can only be measured indirectly. Some results are counter-intuitive. Two boiler manufacturers and a consortium have developed models to predict fouling and corrosion in biomass boilers in order to specify tube materials for particular operating conditions. It would be very useful to compare the predictions of these models regarding corrosion rates and recommended alloys in the boiler environments where field tests will be performed in the current program. Manufacturers of biomass boilers have concluded that it is more cost-effective to restrict steam temperatures, to co-fire biofuels with high sulfur fuels and/or to use fuel additives rather than try to increase fuel efficiency by operating with superheater tube temperatures above melting temperature of fly ash deposits. Similar strategies have been developed for coal fired and waste-fired boilers. Additives are primarily used to replace alkali metal chloride deposits with higher melting temperature and less corrosive alkali metal sulfate or alkali aluminum silicate deposits. Design modifications that have been shown to control superheater corrosion include adding a radiant pass (empty chamber) between the furnace and the superheater, installing cool tubes immediately upstream of the superheater to trap high chloride deposits, designing superheater banks for quick replacement, using an external superheater that burns a less corrosive biomass fuel, moving circulating fluidized bed (CFB) superheaters from the convective pass into the hot recirculated fluidizing medium and adding an insulating layer to superh

BOILER MATERIALS FOR ULTRASUPERCRITICAL COAL POWER PLANTS  

Science Conference Proceedings (OSTI)

The principal objective of this project is to develop materials technology for use in ultrasupercritical (USC) plant boilers capable of operating with 760 C (1400 F), 35 MPa (5000 psi) steam. In the 21st century, the world faces the critical challenge of providing abundant, cheap electricity to meet the needs of a growing global population while at the same time preserving environmental values. Most studies of this issue conclude that a robust portfolio of generation technologies and fuels should be developed to assure that the United States will have adequate electricity supplies in a variety of possible future scenarios. The use of coal for electricity generation poses a unique set of challenges. On the one hand, coal is plentiful and available at low cost in much of the world, notably in the U.S., China, and India. Countries with large coal reserves will want to develop them to foster economic growth and energy security. On the other hand, traditional methods of coal combustion emit pollutants and CO{sub 2} at high levels relative to other generation options. Maintaining coal as a generation option in the 21st century will require methods for addressing these environmental issues. This project has established a government/industry consortium to undertake a five-year effort to evaluate and develop of advanced materials that allow the use of advanced steam cycles in coal-based power plants. These advanced cycles, with steam temperatures up to 760 C, will increase the efficiency of coal-fired boilers from an average of 35% efficiency (current domestic fleet) to 47% (HHV). This efficiency increase will enable coal-fired power plants to generate electricity at competitive rates (irrespective of fuel costs) while reducing CO{sub 2} and other fuel-related emissions by as much as 29%. Success in achieving these objectives will support a number of broader goals. First, from a national prospective, the program will identify advanced materials that will make it possible to maintain a cost-competitive, environmentally acceptable coal-based electric generation option. High sulfur coals will specifically benefit in this respect by having these advanced materials evaluated in high-sulfur coal firing conditions and from the significant reductions in waste generation inherent in the increased operational efficiency. Second, from a national prospective, the results of this program will enable domestic boiler manufacturers to successfully compete in world markets for building high-efficiency coal-fired power plants.

Steam Conservation and Boiler Plant Efficiency Advancements  

E-Print Network (OSTI)

This paper examines several cost-effective steam conservation and boiler plant efficiency advancements that were implemented during a recently completed central steam boiler plant replacement project at a very large semiconductor manufacturing complex. The measures include: 1) Reheating of dehumidified cleanroom make-up air with heat extracted during precooling. 2) Preheating of deionization feedwater with refrigerant heat of condensation. 3) Preheating of boiler combustion air with heat extracted from boiler flue gas. 4) Preheating of boiler feedwater with heat extracted from gas turbine exhaust. 5) Variable speed operation of boiler feedwater pumps and forced-draft fans. 6) Preheating of boiler make-up water with heat extracted from boiler surface blow-down. The first two advancements (steam conservation measures) reduced the amount of steam produced by about 25% and saved about $1,010,000/yr by using recovered waste heat rather than steam-derived heat at selected heating loads. The last four advancements (boiler plant efficiency measures) reduced the unit cost of steam produced by about 13% and saved about $293,500/yr by reducing natural gas and electricity usage at the steam boiler plant. The combined result was a 35% reduction in annual steam costs (fuel and power).

Quantifying Energy Savings by Improving Boiler Operation  

E-Print Network (OSTI)

On/off operation and excess combustion air reduce boiler energy efficiency. This paper presents methods to quantify energy savings from switching to modulation control mode and reducing excess air in natural gas fired boilers. The methods include calculation of combustion temperature, calculation of the relationship between internal convection coefficient and gas flow rate, and calculation of overall heat transfer assuming a parallel-flow heat exchanger model. The method for estimating savings from changing from on/off to modulation control accounts for purge and drift losses through the boiler and the improved heat transfer within the boiler due to the reduced combustion gas flow rate. The method for estimating savings from reducing excess combustion air accounts for the increased combustion temperature, reduced internal convection coefficient and increased residence time of combustion gasses in the boiler. Measured boiler data are used to demonstrate the accuracy of the methods.

Stress-Assisted Corrosion in Boiler Tubes  

Science Conference Proceedings (OSTI)

A number of industrial boilers, including in the pulp and paper industry, needed to replace their lower furnace tubes or decommission many recovery boilers due to stress-assisted corrosion (SAC) on the waterside of boiler tubes. More than half of the power and recovery boilers that have been inspected reveal SAC damage, which portends significant energy and economic impacts. The goal of this project was to clarify the mechanism of stress-assisted corrosion (SAC) of boiler tubes for the purpose of determining key parameters in its mitigation and control. To accomplish this in-situ strain measurements on boiler tubes were made. Boiler water environment was simulated in the laboratory and effects of water chemistry on SAC initiation and growth were evaluated in terms of industrial operations. Results from this project have shown that the dissolved oxygen is single most important factor in SAC initiation on carbon steel samples. Control of dissolved oxygen can be used to mitigate SAC in industrial boilers. Results have also shown that sharp corrosion fatigue and bulbous SAC cracks have similar mechanism but the morphology is different due to availability of oxygen during boiler shutdown conditions. Results are described in the final technical report.

The intent of energy efficiency codes, as related to duct insulation and sealing, is to keep mechanically warmed or cooled air as close to a constant, desired temperature as possible and prevent the conditioned air from escaping the duct system while it is being moved to spaces where it is needed. If reduced heat transfer through insulated ducts is accounted for in the heating, ventilating, and air conditioning (HVAC) load calculations, it may even be possible to reduce the size of HVAC equipment.

Energy savings from operation and maintenance training for apartment boiler heating systems  

SciTech Connect

The Portland Energy Office provided operation and maintenance (O M) training to the operators of boiler heating systems for ten low-income apartment complexes in the Fall of 1990. This study tracked energy usage before and after O M training to see if savings occurred. Training was provided on both weatherized and non-weatherized apartments to find out if weatherization impacted the amount of O M savings to be obtained. Also, energy savings from the O M training and building shell weatherization are compared. The O M training averaged about four hours per building. Content was adjusted at each site to match needs of the boiler and operator. The Energy Office also provided a boiler tune-up by a service technician. The training stressed low-cost and no-cost measures which operators could either do themselves or hire service help to implement. It also emphasized boiler safety. Nine of the ten apartment complexes in the study used less energy per heating degree-day after the O M help. Average savings were 10%. Four apartments chosen randomly as controls had negative savings; they used slightly more energy during the same post-O M time frame. Weatherized and unweatherized apartments showed similar savings after the O M help, 10% and 11% percent respectively. Savings from weatherization of six of the apartments in the winter of 1988--1989 were also measured. A low average of only 4% was observed, reflecting negative savings in two buildings.

Boiler Efficiency vs. Steam Quality- The Challenge of Creating Quality Steam Using Existing Boiler Efficiencies  

E-Print Network (OSTI)

A boiler works under pressure and it is not possible to see what is happening inside of it. The terms "wet steam" and "carry over" are every day idioms in the steam industry, yet very few people have ever seen these phenomena and the actual water movement inside a boiler has remained highly speculative. This paper and support test video of actual boiler operations will illustrate the effects steam quality vs. boiler efficiency during different boiler and steam system demands. There are four different operating situations that effect the steam quality. Each of the following situation will be described in detail using visual aids and supporting literature: Case I: On/Off Feedwater Control: Wide swings in the water level of the boiler can result in unnecessary low water alarms and shut downs. Case II: Reduced Operating Pressure: By running a boiler at a lower pressure, the boiling action within the boiler becomes much more violent causing water to be carried over in to the steam system. Case III: A Demand of 15% over Capacity: Over loading a boiler will cause excessive amounts of water to be carried along with the steam into the system. Case IV: TDS Control: Without proper control of IDS within the boiler carry-over of water into the steam system will occur causing damage to equipment and/or waterhammer.

Reflective Insulation Handbook.  

Science Conference Proceedings (OSTI)

When reflective-foil insulation manufacturers wanted the Bonneville Power Administration (BPA) to include their products in the Residential Weatherization Program, they lacked conclusive test data to prove that their products met program specifications. Reflective foils lacked widespread acceptance because of uncertainty about their insulation values. BPA discovered that the Department of Energy (DOE) and Oak Ridge National Laboratory (ORNL) was preparing a study to test how well reflective foils reduced horizontal heat flow. Because the insulation value of reflective foils depends upon the direction of heat flow, BPA provided additional funding to test their effectiveness in reducing upward and downward heat flow and to produce this Handbook. The objectives of this study were to develop acceptable test and evaluation methods, produce an initial data base of idealized reflective-foil insulation systems, extend this data base to a limited number of commercially available products to develop and test analytical models to predict thermal performance and develop a Reflective Insulation Handbook for homeowners and insulation contractors. This handbook describes how heat is transferred; the function of an insulation; what reflective insulation is; types of reflective insulation; where it can be used; installation procedures; thermal performance; and useful sources of information. 10 figs., 2 tabs.

A Methodology for Optimizing Boiler Operating Strategy  

E-Print Network (OSTI)

Among the many ways by which an energy manager can conserve energy is the establishment of a strategy for operation of fired boilers. In particular, he can effect total fuel consumption by his decision on how much on-line boiler surplus is required. There is a need to be able to balance the cost advantages of operating with less boiler surplus against the potential economic losses that might result from the increased risk of not meeting demand. A methodology for doing this along with an example calculation, is presented in this paper.

Energy Conservation for Boiler Water Systems  

E-Print Network (OSTI)

In the last ten years energy costs have soared. The cost of coal and # 2 fuel oil have gone up by a factor of 3-5. Residual fuel oil cost has increased by approximately ten times. The cost of natural gas has gone up at an even higher rate. This paper reviews methods to conserve energy in industrial boiler water systems. Both mechanical and chemical approaches for energy conservation are discussed. The important aspects of efficient combustion are covered as well as other mechanical factors such as boiler blowdown heat recovery, economizers, air preheaters, and boiler blowdown control. The chemical aspects discussed for energy conservation include fuel additives, boiler internal treatment, and condensate treatments. The emphasis in this paper, for both mechanical and chemical approaches to energy conservation covers three areas: 1) maximizing the use of available Btu's in fuel through more efficient combustion, 2) improving the efficiency of heat transfer, and 3) recovering Btu's that have been previously considered uneconomical.

Water treatment program raises boiler operating efficiency  

Science Conference Proceedings (OSTI)

This report details the boiler water treatment program which played a vital role in changing an aging steam plant into a profitable plant in just three years. Boiler efficiency increased from approximately 70 percent initially to 86 percent today. The first step in this water treatment program involves use of a sodium zeolite water softener that works to remove scale-forming ions from municipal water used in the system. A resin cleaner is also added to prolong the life of resins in the softener. The water is then passed through a new blow-down heat exchanger, which allows preheating from the continuous blow-down from the boiler system. The water gets pumped into a deaerator tank where sulfite treatment is added. The water then passes from feedpumps into the boiler system.

Low Temperature Heat Recovery for Boiler Systems  

E-Print Network (OSTI)

Low temperature corrosion proof heat exchangers designed to reduce boiler flue gas temperatures to 150F or lower are now being commercially operated on gas, oil and coal fired boilers. These heat exchangers, when applied to boiler flue gas, are commonly called condensing economizers. It has traditionally been common practice in the boiler industry to not reduce flue gas temperatures below the 300F to 400F range. This barrier has now been broken by the development and application of corrosion proof heat exchanger technology. This opens up a vast reservior of untapped recoverable energy that can be recovered and reused as an energy source. The successful recovery of this heat and the optimum use of it are the fundemental goals of the technology presented in this paper. This Recovered Low Level Heat Is Normally Used To Heat Cold Make-up Water Or Combustion Air.

Industrial Boiler Optimization Utilizing CO Control  

E-Print Network (OSTI)

Escalating energy costs have caused industry to search the technical section for the current state-of-the-art in combustion and control technology for power generation. Long a forgotten area in many industrial facilities, today the steam generating complex is the focus of many corporate and plant managers. This paper discusses the approach of a large chemical company that is effectively utilizing a direct digital control (DOC) system coupled with the measurement of carbon monoxide to optimize boiler combustion and generate steam in the most cost effective manner. Significant reductions in the amount of excess air have resulted from the use of CO as a control parameter. Previously, combustion effectiveness was determined by the more typical 02 measurement. For reasons of boiler leakage and gas stratification, this control technique was not suitable when operating close to stoichiometry. The use of DOC type control in our multiple boiler installation has also enabled the intelligent allocation of boiler capacity by evaluating steam demand versus incremental boiler steam cost. The system selectively increases or decreases boiler loads within specified constraints to provide the lowest overall steam production cost while continuing to meet the steam demand.

Pipe Insulation Economies  

E-Print Network (OSTI)

Pipe Insulation Economies is a computer program written in IBM basic to simplify the economic insulation thickness for an insulated pipe. Many articles have been written on this subject, from simple nomographs to a small book written in 1976 by the Federal Energy Administration, called "Economic Thickness for Industrial Insulation (ETI)." This paper is meant to fall somewhere between these extremes without sacrificing the accuracy necessary for economic considerations. Within this text, insulation is dealt with not as a material but as a method to slow heat transfer. To simplify the various mechanisms by which heat is transferred, the variable "thermal conductivity" is used. This is modeled for average insulation temperature. Another variable which has caused problems in the past is the ambient air film coefficient, or surface resistance. This program deals with this coefficient by making an initial assumption, then using an iterative process to refine the actual values before making the economic calculations. The program will use the input data to determine first of all the heat loss in BTU per hr/ft. of pipe. Using this result the lowest annual cost, therefore the most economical insulation thickness, is determined.

External Insulation of Masonry Walls and Wood Framed Walls  

Science Conference Proceedings (OSTI)

The use of exterior insulation on a building is an accepted and effective means to increase the overall thermal resistance of the assembly that also has other advantages of improved water management and often increased air tightness of building assemblies. For thin layers of insulation (1" to 1 1/2"), the cladding can typically be attached directly through the insulation back to the structure. For thicker insulation layers, furring strips have been added as a cladding attachment location. This approach has been used in the past on numerous Building America test homes and communities (both new and retrofit applications), and has been proven to be an effective and durable means to provide cladding attachment. However, the lack of engineering data has been a problem for many designers, contractors, and code officials. This research project developed baseline engineering analysis to support the installation of thick layers of exterior insulation on existing masonry and frame walls. Furthermore, water management details necessary to integrate windows, doors, decks, balconies and roofs were created to provide guidance on the integration of exterior insulation strategies with other enclosure elements.

Test Report: Cost Effective Foundation Insulation  

SciTech Connect

A field experiment was conducted to demonstrate and quantify the thermal effectiveness of rigid insulation board when installed on the exterior of a buried concrete foundation wall. A heated, insulated box was constructed along one wall of an existing, unheated building to simulate the living space of a home. The crawl space beneath the living space was divided into two sections. One featured external foundation insulation, while the other side had none. 36 temperature and heat flux sensors were installed at predetermined locations to measure the temperature profile and heat flow out of the living space. The temperature profile through the foundation was then used to calculate the total heat flow out of the foundation for both cases. This experiment showed that a significant energy savings is available with exterior foundation insulation. Over the course of 3 months, the heat-loss differential between the insulated and non-insulated foundations was 4.95 kilowatt-hours per lineal foot of foundation wall, for a ratio of 3:1. For a 2200 sq. ft home with a foundation perimeter 200 ft. long, this would amount to a savings of 990 kW-hrs in just 3 months, or 330 kW-hrs per month. Extrapolating to an 8-month heating year, we would expect to save over 2640 kW-hrs per year for such a home. The savings for a basement foundation, rather than a crawlspace, would be approach twice that amount, nearing 5280 kW-hr per year. Because these data were not collected during the coldest months of the year, they are conservative, and greater savings may be expected during colder periods.

Direct contact, binary fluid geothermal boiler  

DOE Patents (OSTI)

Energy is extracted from geothermal brines by direct contact with a working fluid such as isobutane which is immiscible with the brine in a geothermal boiler. The geothermal boiler provides a distributor arrangement which efficiently contacts geothermal brine with the isobutane in order to prevent the entrainment of geothermal brine in the isobutane vapor which is directed to a turbine. Accordingly the problem of brine carry-over through the turbine causes corrosion and scaling thereof is eliminated. Additionally the heat exchanger includes straightening vanes for preventing startup and other temporary fluctuations in the transitional zone of the boiler from causing brine carryover into the turbine. Also a screen is provided in the heat exchanger to coalesce the working fluid and to assist in defining the location of the transitional zone where the geothermal brine and the isobutane are initially mixed.

Assessment of black liquor recovery boilers  

DOE Green Energy (OSTI)

In the paper making industry, pulpwood chips are digested and cooked to provide the pulp going to the refining and paper mills. Black liquor residue, containing the dissolved lignin binder from the chips, with a concentration of 12 to 16% solids, is further concentrated to 62 to 65% solids and mixed with salt cake, Sodium Sulfate (Na/sub 2/SO/sub 4/). The resulting concentrate of black liquor serves both as a fuel for generating steam in the boiler and also as the mother liquid from which other process liquors are recovered and recycled. Because the black liquor fuel contains high alkali concentrations, 18.3% sodium, 3.6% sulfur, an amount typical of midwestern bituminous coal, and measurable amounts of silica, iron oxides and other species, the black liquor boiler experience was reviewed for application to MHD boiler technology.

Heat Recovery Boilers for Process Applications  

E-Print Network (OSTI)

Heat recovery boilers are widely used in process plants for recovering energy from various waste gas streams, either from the consideration of process or of economy. Sulfuric, as well as nitric, acid plant heat recovery boilers are examples of the use of heat recovery due primarily to process considerations. On the other hand, cost and payback are main considerations in the case of gas turbine and incineration plants, where large quantities of gases are exhausted at temperatures varying from 800F to 1800F. This gas, when recovered, can result in a large energy savings and steam production. This paper attempts to outline some of the engineering considerations in the design of heat recovery boilers for turbine exhaust applications (combined cycle, cogeneration mode), incineration plants (solid waste, fume) and chemical plants (reformer, sulfuric acid, nitric acid).

An outer glazing and inner glazing are sealed to a spacer to form a gas impermeable space. One or more rigid, non-structural glazings are attached to the inside of the spacer to divide the space between the inner and outer glazings to provide insulating gaps between glazings of from about 0.20 inches to about 0.40 inches. One or more glazing surfaces facing each thermal gap are coated with a low emissivity coating. Finally, the thermal gaps are filled with a low conductance gas such as krypton gas.

Super Boiler: Packed Media/Transport Membrane Boiler Development and Demonstration  

Science Conference Proceedings (OSTI)

Gas Technology Institute (GTI) and Cleaver-Brooks developed a new gas-fired steam generation system???¢????????the Super Boiler???¢????????for increased energy efficiency, reduced equipment size, and reduced emissions. The system consists of a firetube boiler with a unique staged furnace design, a two-stage burner system with engineered internal recirculation and inter-stage cooling integral to the boiler, unique convective pass design with extended internal surfaces for enhanced heat transfer, and a novel integrated heat recovery system to extract maximum energy from the flue gas. With these combined innovations, the Super Boiler technical goals were set at 94% HHV fuel efficiency, operation on natural gas with boilers of similar steam output. To demonstrate these technical goals, the project culminated in the industrial demonstration of this new high-efficiency technology on a 300 HP boiler at Clement Pappas, a juice bottler located in Ontario, California. The Super Boiler combustion system is based on two stage combustion which combines air staging, internal flue gas recirculation, inter-stage cooling, and unique fuel-air mixing technology to achieve low emissions rather than external flue gas recirculation which is most commonly used today. The two-stage combustion provides lower emissions because of the integrated design of the boiler and combustion system which permit precise control of peak flame temperatures in both primary and secondary stages of combustion. To reduce equipment size, the Super Boiler's dual furnace design increases radiant heat transfer to the furnace walls, allowing shorter overall furnace length, and also employs convective tubes with extended surfaces that increase heat transfer by up to 18-fold compared to conventional bare tubes. In this way, a two-pass boiler can achieve the same efficiency as a traditional three or four-pass firetube boiler design. The Super Boiler is consequently up to 50% smaller in footprint, has a smaller diameter, and is up to 50% lower in weight, resulting in very compact design with reduced material cost and labor costs, while requiring less boiler room floor space. For enhanced energy efficiency, the heat recovery system uses a transport membrane condenser (TMC), a humidifying air heater (HAH), and a split-stage economizer to extract maximum energy from the flue gas. The TMC is a new innovation that pulls a major portion of water vapor produced by the combustion process from the flue gases along with its sensible and latent heat. This results in nearly 100% transfer of heat to the boiler feed water. The HAH improves the effectiveness of the TMC, particularly in steam systems that do not have a large amount of cold makeup water. In addition, the HAH humidifies the combustion air to reduce NOx formation. The split-stage economizer preheats boiler feed water in the same way as a conventional economizer, but extracts more heat by working in tandem with the TMC and HAH to reduce flue gas temperature. These components are designed to work synergistically to achieve energy efficiencies of 92-94% which is 10-15% higher than today???¢????????s typical firetube boilers.

The next generation of oxy-fuel boiler systems  

SciTech Connect

Research in the area of oxy-fuel combustion which is being pioneered by Jupiter Oxygen Corporation combined with boiler research conducted by the USDOE/Albany Research Center has been applied to designing the next generation of oxy-fuel combustion systems. The new systems will enhance control of boiler systems during turn-down and improve response time while improving boiler efficiency. These next generation boiler systems produce a combustion product that has been shown to be well suited for integrated pollutant removal. These systems have the promise of reducing boiler foot-print and boiler construction costs. The modularity of the system opens the possibility of using this design for replacement of boilers for retrofit on existing systems.

Waste minimization and pollution prevention initiatives within Argonne National Laboratory-East (ANL-E) boiler house operations  

Science Conference Proceedings (OSTI)

The mission of ANL-E Plant Facility and Services-Utilities and Systems (PFS-US) is to operate and maintain utility services in a cost-effective manner, while utilizing new and innovative methods whenever possible. PFS-US operates an on-site coal burning boiler plant that generates steam for use throughout the Laboratory as a source to heat buildings, as well as for use in research experiments. In the recent past, PFS-US has embarked upon a series of initiatives to improve operating efficiency of boiler house operations. The results of these projects have had the following impacts on boiler house performance and operations: (1) boiler house efficiency and operations have improved, (2) boiler house operating costs have been reduced, (3) specific operating and maintenance costs have been avoided or eliminated, and (4) the amount of waste and pollution generated has been reduced. Through the implementation of these initiatives, over $250,000 of revenue and cost savings have been incurred by ANL-E. In addition, the Laboratory and DOE will benefit annually from revenues, cost savings, and the reduction of environmental liability resulting from these initiatives.

Porous insulation in HVAC systems  

Science Conference Proceedings (OSTI)

Porous insulation used to line the air stream surfaces of HVAC equipment provides a locus for the accumulation of dirt and debris. Dirt and debris are hydrophilic and the insulation on the air stream surfaces of mechanical cooling systems thus provides a niche for mold growth. The mold growing on porous insulation unlike moldy debris on a hard surface such as sheetmetal cannot be removed by duct cleaning. Actions for proactively preventing biocontamination of HVAC insulation include the following. (1) Porous insulation shall not be used to line the air stream surfaces of HVAC plenums where wetting is likely such as in the vicinity of cooling coils

Oxy-Combustion Boiler Material Development  

SciTech Connect

Under U.S. Department of Energy Cooperative Agreement No. DE-NT0005262 Foster Wheeler North America Corp conducted a laboratory test program to determine the effect of oxy-combustion on boiler tube corrosion. In this program, CFD modeling was used to predict the gas compositions that will exist throughout and along the walls of air-fired and oxy-fired boilers operating with low to high sulfur coals. Test coupons of boiler tube materials were coated with deposits representative of those coals and exposed to the CFD predicted flue gases for up to 1000 hours. The tests were conducted in electric tube furnaces using oxy-combustion and air-fired flue gases synthesized from pressurized cylinders. Following exposure, the test coupons were evaluated to determine the total metal wastage experienced under air and oxy-combustions conditions and materials recommendations were made. Similar to air-fired operation, oxy-combustion corrosion rates were found to vary with the boiler material, test temperature, deposit composition, and gas composition. Despite this, comparison of air-fired and oxy-fired corrosion rates showed that oxy-firing rates were, for the most part, similar to, if not lower than those of air-firing; this finding applied to the seven furnace waterwall materials (wrought and weld overlay) and the ten superheater/reheater materials (wrought and weld overlay) that were tested. The results of the laboratory oxy-combustion tests, which are based on a maximum bulk flue gas SO2 level of 3200 ppmv (wet) / 4050 ppmv (dry), suggest that, from a corrosion standpoint, the materials used in conventional subcritical and supercritical, air-fired boilers should also be suitable for oxy-combustion retrofits. Although the laboratory test results are encouraging, they are only the first step of a material evaluation process and it is recommended that follow-on corrosion tests be conducted in coal-fired boilers operating under oxy-combustion to provide longer term (one to two year) data. The test program details and data are presented herein.

Key Elements of and Materials Performance Targets for Highly Insulating Key Elements of and Materials Performance Targets for Highly Insulating Window Frames Title Key Elements of and Materials Performance Targets for Highly Insulating Window Frames Publication Type Journal Article LBNL Report Number LBNL-5099E Year of Publication 2011 Authors Gustavsen, Arlid, Steinar Grynning, Dariush K. Arasteh, Bjørn Petter Jelle, and Howdy Goudey Journal Energy and Buildings Volume 43 Issue 10 Pagination 2583-2594 Date Published 10/2011 Keywords Fenestration, heat transfer modeling, thermal performance, thermal transmittance, u-factor, window frames Abstract The thermal performance of windows is important for energy efficient buildings. Windows typically account for about 30-50 percent of the transmission losses though the building envelope, even if their area fraction of the envelope is far less. The reason for this can be found by comparing the thermal transmittance (U-factor) of windows to the U-factor of their opaque counterparts (wall, roof and floor constructions). In well insulated buildings the U-factor of walls, roofs an floors can be between 0.1-0.2 W/(m2K). The best windows have U-values of about 0.7-1.0. It is therefore obvious that the U-factor of windows needs to be reduced, even though looking at the whole energy balance for windows (i.e. solar gains minus transmission losses) makes the picture more complex.

Highly Insulating Windows - Cost  

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

Cost Cost The following is an estimate of the cost effective incremental cost of highly-insulating windows (U-factor=0.20 Btu/hr-ft2-F) compared to regular ENERGY STAR windows (U-factor 0.35 Btu/hr-ft2-F). Energy savings from lower U-factors were simulated with RESFEN over an assumed useful window life of 25 years. To determine the maximum incremental cost at which highly-insulating windows would still be cost-effective, we used a formula used by many utility companies to calculate the cost of saved energy from energy efficiency programs, based on the programs' cost and savings. We turned this formula around so that the cost of saved energy equals the present energy prices in the studied locations, whereas the program cost (the incremental cost of the windows) is the dependent variable.

Insulated pipe clamp design  

SciTech Connect

Thin wall large diameter piping for breeder reactor plants can be subjected to significant thermal shocks during reactor scrams and other upset events. On the Fast Flux Test Facility, the addition of thick clamps directly on the piping was undesired because the differential metal temperatures between the pipe wall and the clamp could have significantly reduced the pipe thermal fatigue life cycle capabilities. Accordingly, an insulated pipe clamp design concept was developed. The design considerations and methods along with the development tests are presented. Special considerations to guard against adverse cracking of the insulation material, to maintain the clamp-pipe stiffness desired during a seismic event, to minimize clamp restraint on the pipe during normal pipe heatup, and to resist clamp rotation or spinning on the pipe are emphasized.

Consider insulation reliability  

SciTech Connect

This paper reports that when calcium silicate and two brands of mineral wool were compared in a series of laboratory tests, calcium silicate was more reliable. And in-service experience with mineral wool at a Canadian heavy crude refinery provided examples of many of the lab's findings. Lab tests, conducted under controlled conditions following industry accepted practices, showed calcium silicate insulation was stronger, tougher and more durable than the mineral wools to which it was compared. For instance, the calcium silicate insulation exhibited only some minor surface cracking when heated to 1,200[degrees]F (649[degrees]C), while the mineral wools suffered binder burnout resulting in sagging, delamination and a general loss of dimensional stability.

Cost-Effective Industrial Boiler Plant Efficiency Advancements  

E-Print Network (OSTI)

Natural gas and electricity are expensive to the extent that annual fuel and power costs can approach the initial cost of an industrial boiler plant. Within this context, this paper examines several cost-effective efficiency advancements that were implemented during a recently completed boiler plant replacement project at a large semiconductor manufacturing complex. The "new" boiler plant began service in November, 1996 and consists of four 75,000 lb/hr water-tube boilers burning natural gas and producing 210 psig saturated steam for heating and humidification. Efficiency advancements include: 1) Reheating of cleanroom make-up air with heat extracted during precooling. 2) Preheating of combustion air with heat extracted from boiler flue gas. 3) Preheating of boiler feedwater with heat extracted from the exhaust of a nearby gas turbine. 4) Variable speed operation of boiler feedwater pumps and forced-draft fans. 5) Preheating of boiler make-up water with heat extracted from boiler blow-down. These efficiency advancements should prove of interest to industrial energy users faced with replacement of aging, inefficient boiler plants, rising fuel and power prices, and increasing pressures to reduce operating costs in order to enhance competitiveness.

BPM2.0. Fossil-Fired Boilers  

Science Conference Proceedings (OSTI)

BOILER PERFORMANCE MODEL (BPM2.0) is a set of programs for predicting the heat transfer performance of fossil-fired utility boilers. The programs can model a wide variety of boiler designs, provide boiler performance estimates for coal, oil or gaseous fuels, determine the influence of slagging and fouling characteristics on boiler performance, and calculate performance factors for tradeoff analyses comparing boilers and fuels. Given a set of target operating conditions, the programs can estimate control settings, gas and steam operating profiles through the boiler, overall boiler efficiency, and fuel consumption. The programs are broken into three categories: data, calculation, and reports with a central processor program acting as the link allowing the user to access any of the data or calculation programs and easily move between programs. The calculations are divided among the following five programs: heat duty calculation, combustion calculation, furnace performance calculation, convection pass performance calculation, and air heater performance calculation. The programs can model subcritical or supercritical boilers, most configurations of convective passes including boilers that achieve final reheat steam temperature control by split back pass, boilers with as many as two reheat circuits and/or multiple attemperator stations in series, and boilers with or without economizers and/or air heaters. Either regenerative or tubular air heaters are supported. For wall-fired or tangentially-fired furnaces, the furnace performance program predicts the temperature of the flue gases leaving the furnace. It accounts for variations in excess air, gas recirculation, burner tilt, wall temperature, and wall cleanliness. For boilers having radiant panels or platens above the furnace, the convective pass program uses the results of the combustion chamber calculation to estimate the gas temperature entering the convective pass.

Recovery of Water from Boiler Flue Gas  

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

RecoveRy of WateR fRom BoileR flue Gas RecoveRy of WateR fRom BoileR flue Gas Background Coal-fired power plants require large volumes of water for efficient operation, primarily for cooling purposes. Public concern over water use is increasing, particularly in water stressed areas of the country. Analyses conducted by the U.S. Department of Energy's National Energy Technology Laboratory predict significant increases in power plant freshwater consumption over the coming years, encouraging the development of technologies to reduce this water loss. Power plant freshwater consumption refers to the quantity of water withdrawn from a water body that is not returned to the source but is lost to evaporation, while water withdrawal refers to the total quantity of water removed from a water source.

Recovery Boiler Superheater Ash Corrosion Field Study  

SciTech Connect

With the trend towards increasing the energy efficiency of black liquor recovery boilers operated in North America, there is a need to utilize superheater tubes with increased corrosion resistance that will permit operation at higher temperatures and pressures. In an effort to identify alloys with improved corrosion resistance under more harsh operating conditions, a field exposure was conducted that involved the insertion of an air-cooled probe, containing six candidate alloys, into the superheater section of an operating recovery boiler. A metallographic examination, complete with corrosion scale characterization using EMPA, was conducted after a 1,000 hour exposure period. Based on the results, a ranking of alloys based on corrosion performance was obtained.

Biomass Cofiring in Coal-Fired Boilers  

DOE Green Energy (OSTI)

Cofiring biomass-for example, forestry residues such as wood chips-with coal in existing boilers is one of the easiest biomass technologies to implement in a federal facility. The current practice is to substitute biomass for up to 20% of the coal in the boiler. Cofiring has many benefits: it helps to reduce fuel costs as well as the use of landfills, and it curbs emissions of sulfur oxide, nitrogen oxide, and the greenhouse gases associated with burning fossil fuels. This Federal Technology Alert was prepared by the Department of Energy's Federal Energy Management Program to give federal facility managers the information they need to decide whether they should pursue biomass cofiring at their facilities.

Highly Insulating Windows - Fram  

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

Frames Frames Research performed at the Norwegian University of Science and Technology and LBNL has identified various highly insulating frame solutions. A report was released in 2007 describing some of these frames. This document reports the findings of a market and research review related to state-of-the-art highly insulating window frames. The market review focuses on window frames that satisfy the Passivhaus requirements (window U-value less or equal to 0.8 W/m2K ), while other examples are also given in order to show the variety of materials and solutions that may be used for constructing window frames with a low thermal transmittance (U-value). The market search shows that several combinations of materials are used in order to obtain window frames with a low U-value. The most common insulating material seems to be Polyurethane (PUR), which is used together with most of the common structural materials such as wood, aluminum, and PVC.

Improved DC Gun Insulator  

SciTech Connect

Many user facilities such as synchrotron light sources and free electron lasers require accelerating structures that support electric fields of 10-100 MV/m, especially at the start of the accelerator chain where ceramic insulators are used for very high gradient DC guns. These insulators are difficult to manufacture, require long commissioning times, and have poor reliability, in part because energetic electrons bury themselves in the ceramic, creating a buildup of charge and causing eventual puncture. A novel ceramic manufacturing process is proposed. It will incorporate bulk resistivity in the region where it is needed to bleed off accumulated charge caused by highly energetic electrons. This process will be optimized to provide an appropriate gradient in bulk resistivity from the vacuum side to the air side of the HV standoff ceramic cylinder. A computer model will be used to determine the optimum cylinder dimensions and required resistivity gradient for an example RF gun application. A ceramic material example with resistivity gradient appropriate for use as a DC gun insulator will be fabricated by glazing using doping compounds and tested.

Improving boiler performance through operator training  

SciTech Connect

The majority of the technical training in many plant facilities is the self-study type. These courses consist of packaged text materials as well as plant specific lessons. Video-based training is more effective than textbooks alone, and computer interactive training is becoming increasingly popular. Demonstration of technical competence can be conducted in a variety of ways: supervised system check off and verification system walk-throughs; simulator evaluation; written examinations required for promotion; and oral examinations. Boiler operators can be required to demonstrate in a practical way that they can apply the boiler plant theory to actual job performance in the plant. Some classifications may be required to perform a supervised system check off and verification before promotion to the next higher classification. Personnel who operate boilers from a control room or gauge board may be required to successfully complete simulator training and evaluation. All classifications may require successful completion of written and oral examinations before being promoted to the next higher classification.

Boiler System Efficiency Improves with Effective Water Treatment  

E-Print Network (OSTI)

Water treatment is an important aspect of boiler operation which can affect efficiency or result in damage if neglected. Without effective water treatment, scale can form on boiler tubes, reducing heat transfer, and causing a loss of boiler efficiency and availability. Proper control of boiler blowdown is also important to assure clean boiler surfaces without wasting water, heat, and chemicals. Recovering hot condensate for reuse as boiler feedwater is another means of improving system efficiency. Condensate which is contaminated with corrosion products or process chemicals, however, is ill fit for reuse; and steam which leaks from piping, valves, traps and connections cannot be recovered. Effective chemical treatment, in conjunction with mechanical system improvements, can assure that condensate can be safely returned and valuable energy recovered.

Prospects for highly insulating window systems  

SciTech Connect

Windows and other fenestration systems are often considered the weakest links in energy-efficient residences. This opinion is reinforced by building standards, audit guidelines, and standard window performance evaluation techniques geared toward sizing building HVAC equipment. In this paper we show that it should be possible to design highly insulating windows (U < 0.12 Btu/hr-ft/sup 2/-F) with high solar transmittances (SC > 0.6). If we then view annual window performance from the basic perspective of control of energy flows, we conclude that it should thus be possible to develop a new generation of ''super window'' that will outperform the best insulated wall or roof for any orientation even in a northern climate. We review several technical approaches that suggest how such a window system might be designed and built. These include multiglazed windows having one or more low-emittance coatings and gas-filled or evacuated cavities. Another approach uses a layer of transparent silica aerogel, a microporus material having a conductivity in air of about R7 per inch. We conclude by presenting data on annual energy performance in a cold climate for a range of ''super windows''. 8 refs., 6 figs.

Recent development in green buildings  

Science Conference Proceedings (OSTI)

Because of the environmental concerns about some materials used in buildings, particularly chlorofluorocarbon (CFC) fluids used as the blowing agent for insulation materials and as refrigerants used in the air conditioning systems have led to a search for environmentally safe alternatives. For insulation materials, new non-CFC blowing agents are still under development. However, the old insulation materials in the buildings will stay because they do not pose any further environmental damage. It is a different story for refrigerants used in air conditioning systems. This study reports that the change-over from CFC to non-CFC refrigerants in the existing and future air conditioning equipment could be a chance not only to take care of the environmental concerns, but to save energy as well. Alternative air conditioning technologies, such as the desiccant dehumidification and absorption systems, and the potential of some natural substances, such as carbon dioxide, as the future refrigerants are also discussed.

Compact vacuum insulation  

DOE Patents (OSTI)

Improved compact insulation panel is provided which is comprised of two adjacent metal sheets spaced close together with a plurality of spherical, or other discretely shaped, glass or ceramic beads optimally positioned between the sheets to provide support and maintain the spacing between the metal sheets when the gases therebetween are evacuated to form a vacuum. These spherical glass beads provide the maximum support while minimizing thermal conductance. In its preferred embodiment; these two metal sheets are textured with ribs or concave protrusions in conjunction with the glass beads to maximize the structural integrity of the panels while increasing the spacing between beads, thereby reducing the number of beads and the number of thermal conduction paths. Glass or porcelain-enameled liners in combination with the glass spacers and metal sidewalls effectively decrease thermal conductivity, and variious laminates, including wood, porcelain-enameled metal, and others effectively increase the strength and insulation capabilities of the panels. Also, a metal web is provided to hold the spacers in place, and strategic grooves are shown to accommodate expansion and contraction or shaping of the panels.

In its preferred embodiment; these two metal sheets are textured with ribs or concave protrusions in conjunction with the glass beads to maximize the structural integrity of the panels while increasing the spacing between beads, thereby reducing the number of beads and the number of thermal conduction paths. Glass or porcelain-enameled liners in combination with the glass spacers and metal sidewalls effectively decrease thermal conductivity, and various laminates, including wood, porcelain-enameled metal, and others effectively increase the strength and insulation capabilities of the panels. Also, a metal web is provided to hold the spacers in place, and strategic grooves are shown to accommodate expansion and contraction or shaping of the panels. 35 figs.

Flame Spectral Analysis for Boiler Control  

E-Print Network (OSTI)

An instrument has been developed by Tecogen, Inc., to determine the combustion characteristics of individual burners in multiburner installations. The technology is based on measuring the emissions in the ultraviolet (UV) and infrared (IR) spectral range from the flames and using these measurements to determine the burner operating conditions. Two prototype instruments have been installed on package boilers at a Con Edison powerplant and Polaroid facility, and their performance has been evaluated. These instruments provide data relating to the variations in the IR and UV spectrum with a change in the combustion condition in individuals burners. This paper describes the instruments operation and these tests.

Condensing Heat Exchangers Optimize Steam Boilers  

E-Print Network (OSTI)

The development of fluorocarbon resin covered tubes has advanced to the point where full scale marketing in connection with condensing heat exchangers has begun. Field installations show simple paybacks of one to one and a half years with resulting steam boiler fuel to steam efficiencies in excess of 90%. The studies and evaluations done to date indicate that units of this type will be cost effective in sizes ranging from 10,000 to 300,0000 steam per hour as long as cold makeup water is available for preheating with the waste flue gases.

Base load fuel comsumption with radiant boiler simulation  

Science Conference Proceedings (OSTI)

The operating point of an oil fired radiant boiler, 580 Megawatt capacity, is critical in maximizing the availability, performance, reliability, and maintainability of a power producing system. Operating the unit above the design operating point causes outages to occur sooner than scheduled. When the boiler is operated below the design operating point, fuel is wasted because the quantity of fuel required to operate a radiant boiler is the same, whether the design setpoint is maintained or not. This paper demonstrates by means of simulation software that the boiler design setpoints is critical to fuel consumption and optimum output megawatts. A boiler with this capacity is used to provide a portion of the base load of an electric utility in order to sustain revenues and maintain reliable generation.

An Insulating Glass Knowledge Base  

SciTech Connect

This report will discuss issues relevant to Insulating Glass (IG) durability performance by presenting the observations and developed conclusions in a logical sequential format. This concluding effort discusses Phase II activities and focuses on beginning to quantifying IG durability issues while continuing the approach presented in the Phase I activities (Appendix 1) which discuss a qualitative assessment of durability issues. Phase II developed a focus around two specific IG design classes previously presented in Phase I of this project. The typical box spacer and thermoplastic spacer design including their Failure Modes and Effect Analysis (FMEA) and Fault Tree diagrams were chosen to address two currently used IG design options with varying components and failure modes. The system failures occur due to failures of components or their interfaces. Efforts to begin quantifying the durability issues focused on the development and delivery of an included computer based IG durability simulation program. The focus/effort to deliver the foundation for a comprehensive IG durability simulation tool is necessary to address advancements needed to meet current and future building envelope energy performance goals. This need is based upon the current lack of IG field failure data and the lengthy field observation time necessary for this data collection. Ultimately, the simulation program is intended to be used by designers throughout the current and future industry supply chain. Its use is intended to advance IG durability as expectations grow around energy conservation and with the growth of embedded technologies as required to meet energy needs. In addition the tool has the immediate benefit of providing insight for research and improvement prioritization. Included in the simulation model presentation are elements and/or methods to address IG materials, design, process, quality, induced stress (environmental and other factors), validation, etc. In addition, acquired data is presented in support of project and model assumptions. Finally, current and suggested testing protocol and procedure for future model validation and IG physical testing are discussed.

SEALED INSULATOR BUSHING  

DOE Patents (OSTI)

The manufacture of electrode insulators that are mechanically strong, shock-proof, vacuum tight, and are capable of withstanding gas pressures of many atmospheres under intense neutron bombardment, such as may be needed in an ionization chamber, is described. The ansulator comprises a bolt within a quartz tube, surrounded by a bushing held in place by two quartz rings, and tightened to a pressure of 1,000 pounds per square inch by a nut and washer. Quartz is the superior material to meet these conditions, however, to withstand this pressure the quartz must be fire polished, lapped to form smooth and parallel surfaces, and again fire polished to form an extremely smooth and fracture resistant mating surface.

Multiple layer insulation cover  

DOE Patents (OSTI)

A multiple layer insulation cover for preventing heat loss in, for example, a greenhouse, is disclosed. The cover is comprised of spaced layers of thin foil covered fabric separated from each other by air spaces. The spacing is accomplished by the inflation of spaced air bladders which are integrally formed in the cover and to which the layers of the cover are secured. The bladders are inflated after the cover has been deployed in its intended use to separate the layers of the foil material. The sizes of the material layers are selected to compensate for sagging across the width of the cover so that the desired spacing is uniformly maintained when the cover has been deployed. The bladders are deflated as the cover is stored thereby expediting the storage process and reducing the amount of storage space required.

The multifamily building evaluation project  

SciTech Connect

In 1991 the New York State Energy Office embarked on a comprehensive multi-year study of multifamily housing in New York City. The principal objective of the evaluation was to determine the degree to which new windows and boiler/burner retrofits installed in 22 multifamily buildings located in the New York City region save energy and whether the savings persist over a minimum of two years. Window and boiler retrofits were selected because they are popular measures and are frequently implemented with assistance from government and utility energy programs. Approaches prospectively, energy consumption monitoring and a series of on-site inspections helped explain why energy savings exceeded or fell short of expectations. In 1993, the scope of the evaluation expanded to include the monitoring of domestic hot water (DHW) consumption in order to better understand the sizing of combined heating/DHW boilers and water consumption patterns. The evaluation was one of ten proposals selected from over 100 candidates in a nationwide competition for a US Department of Energy Building Efficiency Program Grant. The Energy Office managed the project, analyzed the data and prepared the reports, Lawrence Berkeley Laboratory served as technical advisor, and EME Group (New York City) installed meters and dataloggers, collected data, and inspected the retrofits. The New York State Energy Research and Development Authority collaborated with the Energy Office on the DHW monitoring component. Results did not always follow predictable patterns. Some buildings far exceeded energy saving estimates while others experienced an increase in consumption. Persistence patterns were mixed. Some buildings showed a steady decline in energy savings while others demonstrated a continual improvement. A clear advantage of the research design was a frequent ability to explain results.
