Calculation of Fire Severity Factors and Fire Non-Suppression Probabilities For A DOE Facility Fire PRA  

Science Conference Proceedings (OSTI)

Over a 12 month period, a fire PRA was developed for a DOE facility using the NUREG/CR-6850 EPRI/NRC fire PRA methodology. The fire PRA modeling included calculation of fire severity factors (SFs) and fire non-suppression probabilities (PNS) for each safe shutdown (SSD) component considered in the fire PRA model. The SFs were developed by performing detailed fire modeling through a combination of CFAST fire zone model calculations and Latin Hypercube Sampling (LHS). Component damage times and automatic fire suppression system actuation times calculated in the CFAST LHS analyses were then input to a time-dependent model of fire non-suppression probability. The fire non-suppression probability model is based on the modeling approach outlined in NUREG/CR-6850 and is supplemented with plant specific data. This paper presents the methodology used in the DOE facility fire PRA for modeling fire-induced SSD component failures and includes discussions of modeling techniques for: Development of time-dependent fire heat release rate profiles (required as input to CFAST), Calculation of fire severity factors based on CFAST detailed fire modeling, and Calculation of fire non-suppression probabilities.

The application of expansion foam on liquefied natural gas (LNG) to suppress LNG vapor and LNG pool fire thermal radiation  

E-Print Network (OSTI)

Liquefied Natural Gas (LNG) hazards include LNG flammable vapor dispersion and LNG pool fire thermal radiation. A large LNG pool fire emits high thermal radiation thus preventing fire fighters from approaching and extinguishing the fire. One of the strategies used in the LNG industry and recommended by federal regulation National Fire Protection Association (NFPA) 59A is to use expansion foam to suppress LNG vapors and to control LNG fire by reducing the fire size. In its application, expansion foam effectiveness heavily depends on application rate, generator location, and LNG containment pit design. Complicated phenomena involved and previous studies have not completely filled the gaps increases the needs for LNG field experiments involving expansion foam. In addition, alternative LNG vapor dispersion and pool fire suppression methodology, Foamglas pool fire suppression (PFS), is investigated as well. This dissertation details the research and experiment development. Results regarding important phenomena are presented and discussed. Foamglas PFS effectiveness is described. Recommendations for advancing current guidelines in LNG vapor dispersion and pool fire suppression methods are developed. The gaps are presented as the future work and recommendation on how to do the experiment better in the future. This will benefit LNG industries to enhance its safety system and to make LNG facilities safer.

Advancements in low NOx tangential firing systems  

Science Conference Proceedings (OSTI)

The most cost effective method of reducing nitrogen oxide emissions when burning fossil fuels, such as coal, is through in-furnace NOx reduction processes. ABB Combustion Engineering, Inc. (ABB CE), through its ABB Power Plant Laboratories has been involved in the development of such low NOx pulverized coal firing systems for many years. This development effort is most recently demonstrated through ABB CE`s involvement with the U.S. Department of Energy`s (DOE) {open_quotes}Engineering Development of Advanced Coal Fired Low-Emission Boiler Systems{close_quotes} (LEBS) project. The goal of the DOE LEBS project is to use {open_quotes}near term{close_quotes} technologies to produce a commercially viable, low emissions boiler. This paper addresses one of the key technologies within this project, the NOx control subsystem. The foundation for the work undertaken at ABB CE is the TFS 2000{trademark} firing system, which is currently offered on a commercial basis. This system encompasses sub-stoichiometric combustion in the main firing zone for reduced NOx formation. Potential enhancements to this firing system focus on optimizing the introduction of the air and fuel within the primary windbox to provide additional horizontal and vertical staging. As is the case with all in-furnace NOx control processes, it is necessary to operate the system in a manner which does not decrease NOx at the expense of reduced combustion efficiency.

Fire protection countermeasures for containment ventilation systems  

SciTech Connect

The goal of this project is to find countermeasures to protect High Efficiency Particulate Air (HEPA) filters, in exit ventilation ducts, from the heat and smoke generated by fire. Initially, methods were developed to cool fire-heated air by fine water spray upstream of the filters. It was recognized that smoke aerosol exposure to HEPA filters could also cause disruption of the containment system. Through testing and analysis, several methods to partially mitigate the smoke exposure to the HEPA filters were identified. A continuous, movable, high-efficiency prefilter using modified commercial equipment was designed. The technique is capable of protecting HEPA filters over the total time duration of the test fires. The reason for success involved the modification of the prefiltration media. Commercially available filter media has particle sorption efficiency that is inversely proportional to media strength. To achieve properties of both efficiency and strength, rolling filter media were laminated with the desired properties. The approach was Edisonian, but truncation in short order to a combination of prefilters was effective. The application of this technique was qualified, since it is of use only to protect HEPA filters from fire-generated smoke aerosols. It is not believed that this technique is cost effective in the total spectrum of containment systems, especially if standard fire protection systems are available in the space. But in areas of high-fire risk, where the potential fuel load is large and ignition sources are plentiful, the complication of a rolling prefilter in exit ventilation ducts to protect HEPA filters from smoke aerosols is definitely justified.

BARRIER SYSTEM FULL SCALE FIRE TESTING ADDRESSEES  

E-Print Network (OSTI)

All holders of operating licenses for nuclear power reactors, except those who have permanently ceased operations and have certified that fuel has been permanently removed from the reactor vessel, and fuel facilities licensees. PURPOSE The U.S. Nuclear Regulatory Commission (NRC) is issuing this information notice (IN) to inform addressees of the results of Hemyc electrical raceway fire barrier system (ERFBS) full-scale fire tests. The Hemyc ERFBS did not perform for one hour as designed because shrinkage of the Hemyc ERFBS occurred during the testing. It is expected that recipients will review the information for applicability to their facilities and consider actions as appropriate to avoid similar problems. However, suggestions contained in this information notice are not NRC requirements; therefore, no specific action or written response is required. BACKGROUND The Hemyc ERFBS, manufactured by Promatec, Inc., has been installed at nuclear power plants (NPPs) to protect circuits in accordance with regulatory requirements (Reference 1) and plant-specific commitments. As a result of fire protection inspections, unresolved items (URIs) were opened at some nuclear power stations due to questions raised regarding the fire resistance capability of the Hemyc ERFBS (Reference 2). The Office of Nuclear Reactor Regulation (NRR) performed a review of the Hemyc ERFBS (Reference 3) and requested the NRCs Office of Nuclear Regulatory Research (RES) to perform confirmatory testing of this ERFBS. RES performed the testing at the Omega Point Laboratories in Elmendorf, Texas. DISCUSSION This information notice describes the results of the investigation of the fire resistance capability of the Hemyc ERFBS (Attachment 1). The NRC performed two ASTM E 119 furnace tests on a number of cable raceway types that are protected by the Hemyc ERFBS (with and without air gaps) in accordance with the Hemyc ERFBS test plan (see ADAMS Accession No. ML043210141 for a preliminary version of the test plan). The test plan provides ML050890089 IN 2005-07

Gas fired Advanced Turbine System  

SciTech Connect

The primary objective of the first phase of the Advanced Gas Turbine System (ATS) program was the concept definition of an advanced engine system that meets efficiency and emission goals far exceeding those that can be provided with today`s equipment. The thermal efficiency goal for such an advanced industrial engine was set at 50% some 15 percentage points higher than current equipment levels. Exhaust emissions goals for oxides of nitrogen (NO{sub x}), carbon monoxide (CO), and unburned hydrocarbons (UH) were fixed at 8 parts per million by volume (ppmv), 20 ppmv, and 20 ppmv respectively, corrected to 15% oxygen (O{sub 2}) levels. Other goals had to be addressed; these involved reducing the cost of power produced by 10 percent and improving or maintaining the reliability, availability, and maintainability (RAM) at current levels. This advanced gas turbine was to be fueled with natural gas, and it had to embody features that would allow it bum coal or coal derived fuels.

Understanding Corrosion Mechanisms Understanding Corrosion Mechanisms in Oxy-Fired Systems Background In Oxy-fired Systems, oxygen is used for combustion of coal rather than air. It produces flue (exhaust) gas with concentrated carbon dioxide (CO2), thus facilitating its capture and sequestration. An added benefit of oxy-firing is that it reduces or eliminates nitrogen oxide (NO X ) emissions. Additional energy is required with oxy-firing and subsequent carbon sequestration

Test results of lithium pool-air reaction suppression systems  

Science Conference Proceedings (OSTI)

Engineered reaction suppression systems were demonstrated to be effective in suppressing lithium pool-air reactions for lithium quantities up to 100 kg. Lithium pool-air reaction suppression system tests were conducted to evaluate suppression system effectiveness for potential use in fusion facilities in mitigating consequences of postulated lithium spills. Small-scale perforated and sacrificial cover plate suppression systems with delayed inert gas purging proved effective in controlling the lithium-air interaction for lithium quantities near 15 kg at initial temperatures up to 450/sup 0/C. A large-scale suppression system with a sacrificial cover, a diverter plate, an inert gas atmosphere, and remotely retrievable catch pans proved effective in controlling lithium pool-air interaction for a 100-kg lithium discharge at an initial temperature of 550/sup 0/C. This suppression system limited the maximum pool temperature to about 600/sup 0/C less than that expected for a similar lithium pool-air reaction without a suppression system. Lithium aerosol release from this large-scale suppression system was a factor of about 10,000 less than that expected for a lithium pool-air reaction with no suppression system. Remote retrieval techniques for lithium cleanup, such as (1) in-place lithium siphoning and overhead crane dismantling, and (2) lithium catch pan removal by use of an overhead crane, were demonstrated as part of this large-scale test.

This report presents a review of fire protection system operating experiences from particle accelerator, fusion experiment, and other applications. Safety relevant operating experiences and accident information are discussed. Quantitative order-of-magnitude estimates of fire protection system component failure rates and fire accident initiating event frequencies are presented for use in risk assessment, reliability, and availability studies. Safety concerns with these systems are discussed, including spurious operation. This information should be useful to fusion system designers and safety analysts, such as the team working on the Engineering Design Activities for the International Thermonuclear Experimental Reactor.

Fire Fire Nature Bulletin No. 51 Febraury 1, 1946 Forest Preserve District of Cook County Clayton F. Smith, President Roberts Mann, Superintendent of Conservation FIRE Most people firmly believe the ancient notion that the prairies and vacant lots should be burnt off "to make better grass." Many are doing so now. Boys who have seen their parents and neighbors kindling fires on vacant property frequently do likewise on the prairies. Recently there have been four fires in the forest preserves which spread from adjoining land. Burning does more harm than good. True, it gets rid of the old weed stalks and dried grass of last year, so that new grass shows green more quickly. But repeated burnings kill the good, nutritious grasses such as bluegrass, timothy and clover. The wildflowers disappear. All food and nesting cover for birds, rabbits and other wildlife is destroyed, just when they need it most. Thistles thrive. Only tough grasses of little value for pasture or hay, such as crabgrass and quackgrass, and the weeds survive.

Applications of coatings in coal-fired energy systems  

SciTech Connect

Corrosion and erosion of metallic structural materials at elevated temperatures in complex multicomponent gas environments that include particulates are potential problems in many fossil energy systems, especially those using coal as a feedstock. The use of appropriate corrosion-resistant coatings on metallic components offers an avenue to minimize material degradation and extend component life. The purpose of this paper is to review the current status of coating performance in environments typical of pulverized-coal-fired boilers, coal gasification, fluidized-bed combustion, and gas turbines. The paper discusses the complexity of environments in different systems and the coating requirements for acceptable performance. Examples illustrate the morphology and corrosion/erosion performance of coating/structural alloy combinations exposed in some of these systems. La addition, future research and development needs are discussed for coating applications in several coal-fired systems.

Cold Vacuum Dryer (CVD) Facility Fire Protection System Design Description (SYS 24)  

SciTech Connect

This system design description (SDD) addresses the Cold Vacuum Drying (CVD) Facility fire protection system (FPS). The primary features of the FPS for the CVD are a fire alarm and detection system, automatic sprinklers, and fire hydrants. The FPS also includes fire extinguishers located throughout the facility and fire hydrants to assist in manual firefighting efforts. In addition, a fire barrier separates the operations support (administrative) area from the process bays and process bay support areas. Administrative controls to limit combustible materials have been established and are a part of the overall fire protection program. The FPS is augmented by assistance from the Hanford Fire Department (HED) and by interface systems including service water, electrical power, drains, instrumentation and controls. This SDD, when used in conjunction with the other elements of the definitive design package, provides a complete picture of the FPS for the CVD Facility.

Limitations imposed on fire PRA methods as the result of incomplete and uncertain fire event data.  

SciTech Connect

Fire probabilistic risk assessment (PRA) methods utilize data and insights gained from actual fire events in a variety of ways. For example, fire occurrence frequencies, manual fire fighting effectiveness and timing, and the distribution of fire events by fire source and plant location are all based directly on the historical experience base. Other factors are either derived indirectly or supported qualitatively based on insights from the event data. These factors include the general nature and intensity of plant fires, insights into operator performance, and insights into fire growth and damage behaviors. This paper will discuss the potential methodology improvements that could be realized if more complete fire event reporting information were available. Areas that could benefit from more complete event reporting that will be discussed in the paper include fire event frequency analysis, analysis of fire detection and suppression system performance including incipient detection systems, analysis of manual fire fighting performance, treatment of fire growth from incipient stages to fully-involved fires, operator response to fire events, the impact of smoke on plant operations and equipment, and the impact of fire-induced cable failures on plant electrical circuits.

Water augmented indirectly-fired gas turbine systems and method  

SciTech Connect

An indirectly-fired gas turbine system utilizing water augmentation for increasing the net efficiency and power output of the system is described. Water injected into the compressor discharge stream evaporatively cools the air to provide a higher driving temperature difference across a high temperature air heater which is used to indirectly heat the water-containing air to a turbine inlet temperature of greater than about 1,000.degree. C. By providing a lower air heater hot side outlet temperature, heat rejection in the air heater is reduced to increase the heat recovery in the air heater and thereby increase the overall cycle efficiency.

Heat pipe technology for coal-fired power systems  

SciTech Connect

This report summarizes the results of heat pipe R and D activities at Argonne National Laboratory (ANL) during the 1977 to 1984 time period. The heat pipe development efforts were associated with a variety of DOE supported projects involving coal-fired prime movers for stationary power generation. The role of heat pipes for these power systems is in their potential application as thermal transport systems for integrating fluidized bed combustors (FBC) with prime movers ranging from Stirling engines in total energy systems (approx.10 MWe) to closed-cycle gas turbines in central power plants (approx.1000 MWe). The results of initial investigations at ANL demonstrated that high-temperature sodium heat pipes provided the best heat exchanger technology for integrating Stirling engines with coal-fired FBC systems. A major accomplishment included the development and validation of a computer code (ANL/HTP) which calculates heat pipe operating limits and other significant characteristics necessary for power plant design. A number of developmental and prototype heat pipes were designed and fabricated through a subcontract effort with Thermacore, Inc., and delivered to ANL for performance testing. Preliminary test results from ANL's Heat Pipe Test Facility, using induction heating and a gas-water calorimeter to establish energy balances, are given in the report. Test data obtained to date are consistent with ANL/HTP code predictions. 47 refs., 53 figs., 22 tabs.

Coal-fired high performance power generating system. Final report  

SciTech Connect

As a result of the investigations carried out during Phase 1 of the Engineering Development of Coal-Fired High-Performance Power Generation Systems (Combustion 2000), the UTRC-led Combustion 2000 Team is recommending the development of an advanced high performance power generation system (HIPPS) whose high efficiency and minimal pollutant emissions will enable the US to use its abundant coal resources to satisfy current and future demand for electric power. The high efficiency of the power plant, which is the key to minimizing the environmental impact of coal, can only be achieved using a modern gas turbine system. Minimization of emissions can be achieved by combustor design, and advanced air pollution control devices. The commercial plant design described herein is a combined cycle using either a frame-type gas turbine or an intercooled aeroderivative with clean air as the working fluid. The air is heated by a coal-fired high temperature advanced furnace (HITAF). The best performance from the cycle is achieved by using a modern aeroderivative gas turbine, such as the intercooled FT4000. A simplified schematic is shown. In the UTRC HIPPS, the conversion efficiency for the heavy frame gas turbine version will be 47.4% (HHV) compared to the approximately 35% that is achieved in conventional coal-fired plants. This cycle is based on a gas turbine operating at turbine inlet temperatures approaching 2,500 F. Using an aeroderivative type gas turbine, efficiencies of over 49% could be realized in advanced cycle configuration (Humid Air Turbine, or HAT). Performance of these power plants is given in a table.

Slag processing system for direct coal-fired gas turbines  

SciTech Connect

Direct coal-fired gas turbine systems and methods for their operation are provided by this invention. The gas turbine system includes a primary zone for burning coal in the presence of compressed air to produce hot combustion gases and debris, such as molten slag. The turbine system further includes a secondary combustion zone for the lean combustion of the hot combustion gases. The operation of the system is improved by the addition of a cyclone separator for removing debris from the hot combustion gases. The cyclone separator is disposed between the primary and secondary combustion zones and is in pressurized communication with these zones. In a novel aspect of the invention, the cyclone separator includes an integrally disposed impact separator for at least separating a portion of the molten slag from the hot combustion gases.

Spray booth with energy saving and fire protection systems  

SciTech Connect

This invention teaches an improved exhaust system to be used with a paint spray booth and having a continuously operating power exhaust fan. The exhaust system has a damper that is opened when spraying actively is taking place in the spray booth and that is closed when there is no spraying actively taking place in the spray booth. A control switch is mounted in any of several locations to determine when the spray gun is in use or is not in use. Thus, the control switch is actuated when the spray gun is hung up thus indicating a nonuse condition of the spray system; whereupon use of the spray gun lifts the gun from the hook to indicate spraying activity. A motor drives the damper to the opened position; and a spring biases the damper to the closed position. A timer is also used to delay the closing of the damper until between twenty and possibly two hundred seconds have lapsed after spraying activity has terminated. This purges the spray booth while yet allows for automatic damper control under normal spraying sequences of use and nonuse. A fire sensing switch is used to deenergize the damper motor to allow the damper to be closed in the event of a fire.

Coal-fired high performance power generating system  

SciTech Connect

The goals of the program are to develop a coal-fired high performance power generation system (HIPPS) by the year 2000 that is capable of > 47% thermal efficiency; NO[sub x] SO [sub x] and Particulates < 25% NSPS; Cost of electricity 10% lower; coal > 65% of heat input and all solid wastes benign. In order to achieve these goals our team has outlined a research plan based on an optimized analysis of a 250 MW[sub e] combined cycle system applicable to both frame type and aeroderivative gas turbines. Under the constraints of the cycle analysis we have designed a high temperature advanced furnace (HITAF) which integrates several combustor and air heater designs with appropriate ash management procedures. Most of this report discusses the details of work on these components, and the R D Plan for future work. The discussion of the combustor designs illustrates how detailed modeling can be an effective tool to estimate NO[sub x] production, minimum burnout lengths, combustion temperatures and even particulate impact on the combustor walls. When our model is applied to the long flame concept it indicates that fuel bound nitrogen will limit the range of coals that can use this approach. For high nitrogen coals a rapid mixing, rich-lean, deep staging combustor will be necessary. The air heater design has evolved into two segments: a convective heat exchanger downstream of the combustion process; a radiant panel heat exchanger, located in the combustor walls; The relative amount of heat transferred either radiatively or convectively will depend on the combustor type and the ash properties.

An evaluation of the fire barrier system thermo-lag 330-1  

SciTech Connect

This report presents the results of three fire endurance tests and one ampacity derating test set of the fire barrier system Thermo-Lag 330-1 Subliming Coating. Each test was performed using cable tray specimens protected by a nominal three-hour fire barrier envelope comprised of two layers of nominal 1/2 inch thick material. The fire barrier systems for two of the three fire endurance test articles and for the ampacity derating test article were installed in accordance with the manufacturer`s installations procedures. The barrier system for the third fire endurance test article was a full reproduction of one of the original manufacturer`s qualification test articles. This final test article included certain installation enhancements not considered typical of current nuclear power plant installations. The primary criteria for fire endurance performance evaluation was based on cable circuit integrity testing. Secondary consideration was also given to the temperature rise limits set forth in the ASTM E119 standard fire barrier test procedure. All three of the fire endurance specimens failed prematurely. Circuit integrity failures for the two fire endurance test articles with procedures-based installations were recorded at approximately 76 and 59 minutes into the exposures for a 6 inch wide and 12 inch wide cable tray respectively. Temperature excursion failures (single point) for these two test articles were noted at approximately 65 and 56 minutes respectively. The first circuit integrity failure for the full reproduction test article was recorded approximately 119 minutes into the exposure, and the first temperature excursion failure for this test article was recorded approximately 110 minutes into the exposure.

Suppression of dynamics in coupled discrete systems in interaction with an extended environment  

E-Print Network (OSTI)

We report the suppression of dynamics and occurrence of quiescent states in an extended system of coupled discrete dynamical systems. This phenomenon is induced by interaction with another similar system with a different and damped dynamics which we call an extended environment. Both the system and the environment are in a feedback loop and their mutual influence leads to suppression of dynamic activity. We illustrate this in the specific case of a system of coupled neurons modelled by a 2-dimensional discrete system called Rulkov maps. A detailed analysis is carried out by considering single units of discrete systems where control to steady states is induced by an external damped system. This is then extended to rings and lattices. As an important application, we also present how the excitation waves produced due to defect neurons can be suppressed by interaction with a system of passive cells.

Design criteria document, Fire Protection Task, K Basin Essential Systems Recovery, Project W-405  

Science Conference Proceedings (OSTI)

The K Basin were constructed in the early 1950`s with a 20 year design life. The K Basins are currently in their third design life and are serving as a near term storage facility for irradiated N Reactor fuel until an interim fuel storage solution can be implemented. In April 1994, Project W-405, K Basin Essential Systems Recovery, was established to address (among other things) the immediate fire protection needs of the 100K Area. A Fire Barrier Evaluation was performed for the wall between the active and inactive areas of the 105KE and 105KW buildings. This evaluation concludes that the wall is capable of being upgraded to provide an equivalent level of fire resistance as a qualified barrier having a fire resistance rating of 2 hours. The Fire Protection Task is one of four separate Tasks included within the scope of Project W405, K Basin Essential systems Recovery. The other three Tasks are the Water Distribution System Task, the Electrical System Task, and the Maintenance Shop/Support Facility Task. The purpose of Project W-405`s Fire Protection Task is to correct Life Safety Code (NFPA 101) non-compliances and to provide fire protection features in Buildings 105KE, 105KW and 190KE that are essential for assuring the safe operation and storage of spent nuclear fuel at the 100K Area Facilities` Irradiated Fuel Storage Basins (K Basins).

Understanding Corrosion Mechanisms in Oxy-Fired Systems  

SciTech Connect

Replacing air with oxygen in coal-fired boilers (i.e. oxy-firing) combined with flue gas recirculation is a leading strategy to concentrate CO{sub 2} and assist in carbon capture and sequestration. A significant area of concern is the fireside corrosion with oxy-firing due to the higher CO{sub 2} levels in the combustion gas and potentially higher SO{sub x} and H{sub 2}O levels. In order to investigate this complicated issue, laboratory experiments are being conducted with and without synthetic ash to assess the potential effect of oxy-firing on fireside corrosion rates. The initial results of this project focus on commercial and model Fe-base alloys at 600 C. Without ash, a 50%H{sub 2}O-50%(CO{sub 2}-0.15O{sub 2}) environment was the most aggressive condition, requiring higher Cr contents than 100% H{sub 2}O or Ar-50%CO{sub 2}. With the specimens covered in ash, several gas compositions were examined, including different levels of H{sub 2}O and SO{sub 2} to simulate various oxy-firing strategies. Results also are presented for several laser-clad coating compositions for protecting tubes. An additional task is examining the effect of environment on mechanical properties. Initial work studied Ni-base alloys in steam at 800 C and found little effect of steam on the creep rupture life of alloy 230 but a 35% decrease for alloy 740.

Flame quality monitor system for fixed firing rate oil burners  

DOE Patents (OSTI)

A method and apparatus for determining and indicating the flame quality, or efficiency of the air-fuel ratio, in a fixed firing rate heating unit, such as an oil burning furnace, is provided. When the flame brightness falls outside a preset range, the flame quality, or excess air, has changed to the point that the unit should be serviced. The flame quality indicator output is in the form of lights mounted on the front of the unit. A green light indicates that the flame is about in the same condition as when the burner was last serviced. A red light indicates a flame which is either too rich or too lean, and that servicing of the burner is required. At the end of each firing cycle, the flame quality indicator goes into a hold mode which is in effect during the period that the burner remains off. A yellow or amber light indicates that the burner is in the hold mode. In this mode, the flame quality lights indicate the flame condition immediately before the burner turned off. Thus the unit can be viewed when it is off, and the flame condition at the end of the previous firing cycle can be observed.

The flame quality indicator output is in the form of lights mounted on the front of the unit. A green light indicates that the flame is about in the same condition as when the burner was last serviced. A red light indicates a flame which is either too rich or too lean, and that servicing of the burner is required. At the end of each firing cycle, the flame quality indicator goes into a hold mode which is in effect during the period that the burner remains off. A yellow or amber light indicates that the burner is in the hold mode. In this mode, the flame quality lights indicate the flame condition immediately before the burner turned off. Thus the unit can be viewed when it is off, and the flame condition at the end of the previous firing cycle can be observed.

Development of a Software System to Facilitate Implementation of Coal and Wood Co-Fired Bilers  

E-Print Network (OSTI)

Coal and wood co-fired boiler technology has improved significantly over the years. The term "co-firing", when used by members of the biomass or utility communities, has come to mean mixing a modest amount of clean, dry sawdust with coal and burning the sawdust coal mixture in a large, coal-burning, utility boiler. This paper discusses the development of a computer software system that interacts with the user and allows coal-wood co-fired boilers to be sized, priced, implemented, and operated properly. Information about the equipment that is required for the boiler replacement project is provided. Along with these features, the software would allow the user to determine energy and cost savings that would be available upon installation as compared to other types of boilers. The paper outlines how these savings are realized, and the steps that must be taken to ensure the proper operation of the boiler to achieve these savings. A sensitivity analysis has also been performed on the implementation of coal-wood co-fired boilers in order to determine the key factors influencing the project payback period. The key factors that are considered in the analysis are the boiler size, the annual operating hours, and the current fuel cost. Additional analysis has been done on the boiler size and the annual operating hours. This analysis allows the users to determine if their current facility falls into the feasible range for implementing a coal-wood co-fired boiler system.

Development of a high-performance coal-fired power generating system with pyrolysis gas and char-fired high temperature furnace (HITAF)  

SciTech Connect

A concept for an advanced coal-fired combined-cycle power generating system is currently being developed. The first phase of this three-phase program consists of conducting the necessary research and development to define the system, evaluate the economic and technical feasibility of the concept, and prepare an R D plan to develop the concept further. Foster Wheeler Development Corporation is leading a team ofcompanies involved in this effort. The system proposed to meet these goals is a combined-cycle system where air for a gas turbine is indirectly heated to approximately 1800[degrees]F in furnaces fired with cool-derived fuels and then directly heated in a natural-gas-fired combustor up to about 2400[degrees]F. The system is based on a pyrolyzing process that converts the coal into a low-Btu fuel gas and char. The fuelgas is a relatively clean fuel, and it is fired to heat tube surfaces that are susceptible to corrosion and problems from ash deposition. In particular, the high-temperature air heater tubes, which will need tobe a ceramic material, will be located in a separate furnace or region of a furnace that is exposed to combustion products from the low-Btu fuel gas only. A simplified process flow diagram is shown.

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

December 20, 2005 December 20, 2005 Novel Coal-Fired Heating System Proves Successful at Ohio Greenhouse Cost Savings and State EPA Standards Achieved in First Commercial Demonstration WASHINGTON, DC - Using a Department of Energy - funded coal-fired technology, a greenhouse in northeast Ohio is saving more than $1,000 a day in heating costs. The efficient fluidized-bed combustion unit provides an alternative to natural gas systems and, using locally available coal and limestone, surpasses state EPA standards for sulfur capture and stack emissions. "The promise of the unit lies in its novel design," said Donald Bonk, a senior technical advisor for the National Energy Technology Laboratory (NETL), which manages the project for the Energy Department. "The fluidized-bed combustion system features flue-gas recirculation, replacing conventional, more expensive boiler tubes. By recycling the flue gas, the system better controls internal temperatures to burn fuel, reducing the formation of pollutants."

ENGINEERING DEVELOPMENT OF COAL-FIRED HIGH-PERFORMANCE POWER SYSTEMS  

SciTech Connect

A High Performance Power System (HIPPS) is being developed. This system is a coal-fired, combined cycle plant with indirect heating of gas turbine air. Foster Wheeler Development Corporation and a team consisting of Foster Wheeler Energy Corporation, Bechtel Corporation, University of Tennessee Space Institute and Westinghouse Electric Corporation are developing this system. In Phase 1 of the project, a conceptual design of a commercial plant was developed. Technical and economic analyses indicated that the plant would meet the goals of the project which include a 47 percent efficiency (HHV) and a 10 percent lower cost of electricity than an equivalent size PC plant. The concept uses a pyrolyzation process to convert coal into fuel gas and char. The char is fired in a High Temperature Advanced Furnace (HITAF). The HITAF is a pulverized fuel-fired boiler/air heater where steam is generated and gas turbine air is indirectly heated. The fuel gas generated in the pyrolyzer is then used to heat the gas turbine air further before it enters the gas turbine. The project is currently in Phase 2, which includes engineering analysis, laboratory testing and pilot plant testing. Research and development is being done on the HIPPS systems that are not commercial or being developed on other projects. Pilot plant testing of the pyrolyzer subsystem and the char combustion subsystem are being done separately, and after each experimental program has been completed, a larger scale pyrolyzer will be tested at the Power Systems Development Facility (PSDF) in Wilsonville, AL. The facility is equipped with a gas turbine and a topping combustor, and as such, will provide an opportunity to evaluate integrated pyrolyzer and turbine operation. This report addresses the areas of technical progress for this quarter. In order to prepare the CETF for the HIPPS char combustion test program, the following three subsystems were designed during this quarter: (1) Flue Gas Recycle System; (2) Pulverized Coal Feed System; and (3) Limestone Feed System The flue gas recycle system is added to simulate the performance of a commercial char burner fired with gas turbine exhaust. Since synthetically made char will be used for the tests at the CETF, the limestone injection system was added to produce a char more representative of that from an actual pyrolyzer. The pulverized coal system is included to provide a supplemental support fuel if a stable flame can not be maintained with char firing only.

Development and design of an advanced pulverized coal-fired system  

SciTech Connect

Under the US Department of Energy (DOE) project `Engineering Development of Advanced Coal-Fired Low-Emission Boiler Systems` (LEBS) the ABB team developed the design of a 400 MWe advanced pulverized coal fired electric generating system. The work and the results are described in the paper. Early work included concept development and evaluation of several subsystems for controlling the emission of SO{sub 2}, NO{sub x}, particulates and for reducing wastes. Candidate technologies were then evaluated in various combinations as part of complete advanced supercritical power generation systems. One system was selected for the design of the advanced generating system. Pilot scale testing is now being conducted to support the design of subsystems. The design meets the overall objective of the LEBS Project by dramatically improving environmental performance of pulverized coal fired power plants without adversely impacting efficiency or the cost of electricity. Advanced technologies will be used to reduce NO{sub x}, SO{sub 2}, and particulate emissions to one-fifth to one-tenth of current NSPS limits. Air toxics will be in compliance, and wastes will be reduced and made more disposable. Net station (HHV) efficiency can be increased to 45 percent without increasing the cost of electricity.

Reliability estimation for multiunit nuclear and fossil-fired industrial energy systems  

SciTech Connect

The purpose of this paper is twofold: to report industrial experience with process energy system reliability, and to assess the reliability of multiunit nuclear and fossil-fired energy systems in an industrial setting. Reliability here refers to the percentage of clock time that sufficient amounts of steam energy were available to permit desired production quotas to be met at a particular plant. A nationwide survey was conducted to obtain data relative to energy system reliabilities during 1973--74, and these data for 29 plants from chemicals and allied products (S.I.C. 28), petroleum refining and related industries (S.I.C. 29) and primary metals industries (S.I.C. 33) are reported here. A simulation model in which various operating characteristics of the energy systems were taken into account was developed to obtain estimates of reliabilities of proposed multiunit nuclear and fossil-fired systems. Based on several example problems evaluated with the simulation model, study results indicated that multiple nuclear units or a combination of nuclear and fossil-fired units could provide adequate reliability to meet large-scale industrial requirements for continuity of service.

ULTRA LOW NOx INTEGRATED SYSTEM FOR NOx EMISSION CONTROL FROM COAL-FIRED BOILERS  

Science Conference Proceedings (OSTI)

ALSTOM Power Inc.'s Power Plant Laboratories, working in concert with ALSTOM Power's Performance Projects Group, has teamed with the U.S. Department of Energy's National Energy Technology Laboratory (DOE NETL) to conduct a comprehensive study to develop/evaluate low-cost, efficient NOx control technologies for retrofit to pulverized coal fired utility boilers. The objective of this project was to develop retrofit NOx control technology to achieve less than 0.15 lb/MMBtu NOx (for bituminous coals) and 0.10 lb/MMBtu NOx (for subbituminous coals) from existing pulverized coal fired utility boilers at a cost which is at least 25% less than SCR technology. Efficient control of NOx is seen as an important, enabling step in keeping coal as a viable part of the national energy mix in this century, and beyond. Presently 57% of U.S. electrical generation is coal based, and the Energy Information Agency projects that coal will maintain a lead in U.S. power generation over all other fuel sources for decades (EIA 1998 Energy Forecast). Yet, coal-based power is being strongly challenged by society's ever-increasing desire for an improved environment and the resultant improvement in health and safety. The needs of the electric-utility industry are to improve environmental performance, while simultaneously improving overall plant economics. This means that emissions control technology is needed with very low capital and operating costs. This project has responded to the industry's need for low NOx emissions by evaluating ideas that can be adapted to present pulverized coal fired systems, be they conventional or low NOx firing systems. The TFS 2000{trademark} firing system has been the ALSTOM Power Inc. commercial offering producing the lowest NOx emission levels. In this project, the TFS 2000{trademark} firing system served as a basis for comparison to other low NOx systems evaluated and was the foundation upon which refinements were made to further improve NOx emissions and related combustion performance. Three coals were evaluated during the bench-scale and large pilot-scale testing tasks. The three coals ranged from a very reactive Powder River Basin coal (PRB) to a moderately reactive Midwestern bituminous coal (HVB) to a less reactive medium volatile Eastern bituminous coal (MVB). Bench-scale testing was comprised of standard ASTM properties evaluation, plus more detailed characterization of fuel properties through drop tube furnace testing and thermogravimetric analysis.

System and method that suppresses intensity fluctuations for free space high-speed optical communication  

DOE Patents (OSTI)

A high-speed (Gbps), free space optical communication system is based on spectral encoding of radiation from a wide band light source, such as a laser. By using partially coherent laser beams in combination with a relatively slow photosensor, scintillations can be suppressed by orders of magnitude for distances of more than 10 km. To suppress the intensity fluctuations due to atmospheric turbulence, a source with partial transverse coherence in combination with slow response time photodetector is used. Information is encoded in the spectral domain of a wideband optical source by modulation of spectral amplitudes. A non-coherent light source with wide spectrum (an LED, for example) may be used for high-speed communication over short (less than about a mile) distances.

Dilution-based emissions sampling from stationary sources: part 2 - gas-fired combustors compared with other fuel-fired systems  

SciTech Connect

With the recent focus on fine particle matter (PM2.5), new, self- consistent data are needed to characterize emissions from combustion sources. Emissions data for gas-fired combustors are presented, using dilution sampling as the reference. The sampling and analysis of the collected particles in the presence of precursor gases, SO{sub 2}, nitrogen oxide, volatile organic compound, and NH{sub 3} is discussed; the results include data from eight gas fired units, including a dual- fuel institutional boiler and a diesel engine powered electricity generator. These data are compared with results in the literature for heavy-duty diesel vehicles and stationary sources using coal or wood as fuels. The results show that the gas-fired combustors have very low PM2.5 mass emission rates in the range of {approximately}10{sup -4} lb/million Btu (MMBTU) compared with the diesel backup generator with particle filter, with {approximately} 5 x 10{sup -3} lb/MMBTU. Even higher mass emission rates are found in coal-fired systems, with rates of {approximately} 0.07 lb/MMBTU for a bag-filter-controlled pilot unit burning eastern bituminous coal. The characterization of PM2.5 chemical composition from the gas-fired units indicates that much of the measured primary particle mass in PM2.5 samples is organic or elemental carbon and, to a much less extent, sulfate. Metal emissions are low compared with the diesel engines and the coal- or wood-fueled combustors. The metals found in the gas- fired combustor particles are low in concentration. The interpretation of the particulate carbon emissions is complicated by the fact that an approximately equal amount of particulate carbon is found on the particle collector and a backup filter. It is likely that measurement artifacts are positively biasing 'true' particulate carbon emissions results. 49 refs., 1 fig., 12 tabs.

Parameters affecting nitrogen oxides in a Coal-Fired Flow Facility system  

DOE Green Energy (OSTI)

The unusually high temperature in the primary combustor of the Coal-Fired Magnetohydrodynamics (MHD) power generation system causes much higher nitrogen oxides (NO{sub x}) to be produced than in a conventional coal fired generation system. In order to lower the NO{sub x} concentration to an acceptable level, it is important to know how parameters of the MM power generation system affect the NO{sub x} concentration. This thesis investigates those effects in the Coal-Fired Flow Facility (CFFF) at the University of Tennessee Space Institute under the contract of US Department Of Energy (DOE). With thermodynamic and kinetic computer codes, the theoretical studies were carried out on the parameters of the CFFF system. The results gathered from the computer codes were analyzed and compared with the experimental data collected during the LMF5J test. The thermodynamic and kinetic codes together modeled the NO.{sub x} behavior with reasonable accuracy while some inconsistencies happened at the secondary combustor inlet.

Development and demonstration of a solid fuel-fired gas turbine system  

SciTech Connect

Western Research Institute (WRI) and Power Generating Incorporated (PGI) are developing a solid fuel-fired gas turbine system for specialized cogeneration applications. The system is based on a patented pressurized combustor designed and tested by PGI in conjunction with McConnell Industries. The other components of the system are (a) fuel receiving, preparation, storage and feeding system, (b) gas clean-up equipment, and (c) a gas turbine generator. An approximately 400 kW prototype system is under construction at the WRI facilities in Laramie, Wyoming. As a part of this demonstration the integrated system, following a short shakedown period, will be operated on white wood. White wood was selected as the fuel for early tests because of its low ash (0.5 - 1.0 %), silica, and sulfur contents. The system will then be operated on coal. It is expected that the design of the coal-based system will evolve as the wood testing proceeds. In previous similar wood-fired system development attempts, albeit at lower turbine inlet temperatures, a major technical hindrance to long-term operation of a gas turbine power system has been the degradation of the hot section of the gas turbine. Deposition, erosion, and corrosion are main issues that need to be addressed. In the wood-fired PGI system, erosion is not likely to be of concern because of the low silica and low overall ash content of the fuel and the fact that the wood ash particle size is expected to be in the range where little or no erosion would be expected. However, because of the high alkali content of the fuel, deposition and corrosion can become major issues. This paper will deal with the issues pertaining to the design of the prototype being constructed at the WRI premises. Preliminary thoughts on the design aspects of the plant modifications required for coal testing will also be presented.

Gas fired advanced turbine system. Phase 1, System scoping and feasibility studies  

DOE Green Energy (OSTI)

The basic concept thus derived from the Ericsson cycle is an intercooled, recuperated, and reheated gas turbine. Theoretical performance analyses, however, showed that reheat at high turbine rotor inlet temperatures (TRIT) did not provide significant efficiency gains and that the 50 percent efficiency goal could be met without reheat. Based upon these findings, the engine concept adopted as a starting point for the gas-fired advanced turbine system is an intercooled, recuperated (ICR) gas turbine. It was found that, at inlet temperatures greater than 2450{degrees}F, the thermal efficiency could be maintained above 50%, provided that the turbine cooling flows could be reduced to 7% of the main air flow or lower. This dual and conflicting requirement of increased temperatures and reduced cooling will probably force the abandonment of traditional air cooled turbine parts. Thus, the use of either ceramic materials or non-air cooling fluids has to be considered for the turbine nozzle guide vanes and turbine blades. The use of ceramic components for the proposed engine system is generally preferred because of the potential growth to higher temperatures that is available with such materials.

Development and demonstration of a wood-fired gas turbine system  

DOE Green Energy (OSTI)

Power Generating Inc. (PGI) has developed and patented a unique direct-fired gas turbine power system (PGI Power System) that operates on solid wood-based fuels. The PGI Power System is designed to generate from 500 kilowatts to 3.5 megawatts of electrical power and up to 30 million Btu per hour of thermal energy for various industrial and utility applications. The system is expected to operate at thermal efficiency levels greater than 70% through full utilization of both the electrical and thermal energy it generates at a specific host facility. PGI and WRI built a 450-kW prototype system at the Western Research Institute (WRI) facilities in Laramie, Wyoming, to demonstrate the technical and economic viability of the PGI Power System. The plant has undergone a brief shakedown, and is presently being operated on white wood. In previous attempts to develop similar systems, the major technical hindrance to long-term operation of a gas turbine power system has been degradation of the hot section in the gas turbine. This problem is overcome in the PGI Power System through its unique design, by closely controlling fuel specifications, and by developing specialized operating procedures. In wood-fired testing conducted to date, no degradation in the engine performance is obvious.

Ammonia slip measurements that were made by a tunable diode laser (TDL) were conducted on a lignite-fired unit with a selective catalytic reduction (SCR) system using a newly developed adjustable flange assembly for dynamic alignment of cross-duct measurements. The single path optics were integrated with a fiber opticcoupled TDL system (Unisearch LasIR) and two shields to allow measurements over the 25-foot (7.62-meter) flue gas duct dimension. The nominal 4.5-foot (1.67-meter) shields were required to ...

Development of a numerical computer code and circuit element models for simulation of firing systems  

SciTech Connect

Numerical simulation of firing systems requires both the appropriate circuit analysis framework and the special element models required by the application. We have modified the SPICE circuit analysis code (version 2G.6), developed originally at the Electronic Research Laboratory of the University of California, Berkeley, to allow it to be used on MSDOS-based, personal computers and to give it two additional circuit elements needed by firing systems--fuses and saturating inductances. An interactive editor and a batch driver have been written to ease the use of the SPICE program by system designers, and the interactive graphical post processor, NUTMEG, supplied by U. C. Berkeley with SPICE version 3B1, has been interfaced to the output from the modified SPICE. Documentation and installation aids have been provided to make the total software system accessible to PC users. Sample problems show that the resulting code is in agreement with the FIRESET code on which the fuse model was based (with some modifications to the dynamics of scaling fuse parameters). In order to allow for more complex simulations of firing systems, studies have been made of additional special circuit elements--switches and ferrite cored inductances. A simple switch model has been investigated which promises to give at least a first approximation to the physical effects of a non ideal switch, and which can be added to the existing SPICE circuits without changing the SPICE code itself. The effect of fast rise time pulses on ferrites has been studied experimentally in order to provide a base for future modeling and incorporation of the dynamic effects of changes in core magnetization into the SPICE code. This report contains detailed accounts of the work on these topics performed during the period it covers, and has appendices listing all source code written documentation produced.

Development of a high-performance coal-fired power generating system with pyrolysis gas and char-fired high temperature furnace (HITAF). Volume 1, Final report  

SciTech Connect

A major objective of the coal-fired high performance power systems (HIPPS) program is to achieve significant increases in the thermodynamic efficiency of coal use for electric power generation. Through increased efficiency, all airborne emissions can be decreased, including emissions of carbon dioxide. High Performance power systems as defined for this program are coal-fired, high efficiency systems where the combustion products from coal do not contact the gas turbine. Typically, this type of a system will involve some indirect heating of gas turbine inlet air and then topping combustion with a cleaner fuel. The topping combustion fuel can be natural gas or another relatively clean fuel. Fuel gas derived from coal is an acceptable fuel for the topping combustion. The ultimate goal for HIPPS is to, have a system that has 95 percent of its heat input from coal. Interim systems that have at least 65 percent heat input from coal are acceptable, but these systems are required to have a clear development path to a system that is 95 percent coal-fired. A three phase program has been planned for the development of HIPPS. Phase 1, reported herein, includes the development of a conceptual design for a commercial plant. Technical and economic feasibility have been analysed for this plant. Preliminary R&D on some aspects of the system were also done in Phase 1, and a Research, Development and Test plan was developed for Phase 2. Work in Phase 2 include s the testing and analysis that is required to develop the technology base for a prototype plant. This work includes pilot plant testing at a scale of around 50 MMBtu/hr heat input. The culmination of the Phase 2 effort will be a site-specific design and test plan for a prototype plant. Phase 3 is the construction and testing of this plant.

Heat Transfer and Thermophotovoltaic Power Generation in Oil-fired Heating Systems  

SciTech Connect

The focus of this study is the production of electric power in an oil-fired, residential heatingsystem using thermophotovoltaic (TPV) conversion devices. This work uses experimental, computational, and analytical methods to investigate thermal mechanisms that drive electric power production in the TPV systems. An objective of this work is to produce results that will lead to the development of systems that generate enough electricity such that the boiler is self-powering. An important design constraint employed in this investigation is the use of conventional, yellow-flame oil burners, integrated with a typical boiler. The power production target for the systems developed here is 100 W - the power requirement for a boiler that uses low-power auxiliary components. The important heattransfer coupling mechanisms that drive power production in the systems studied are discussed. The results of this work may lead to the development of systems that export power to the home electric system.

Install Waste Heat Recovery Systems for Fuel-Fired Furnaces (English/Chinese) (Fact Sheet)  

SciTech Connect

Chinese translation of ITP fact sheet about installing Waste Heat Recovery Systems for Fuel-Fired Furnaces. For most fuel-fired heating equipment, a large amount of the heat supplied is wasted as exhaust or flue gases. In furnaces, air and fuel are mixed and burned to generate heat, some of which is transferred to the heating device and its load. When the heat transfer reaches its practical limit, the spent combustion gases are removed from the furnace via a flue or stack. At this point, these gases still hold considerable thermal energy. In many systems, this is the greatest single heat loss. The energy efficiency can often be increased by using waste heat gas recovery systems to capture and use some of the energy in the flue gas. For natural gas-based systems, the amount of heat contained in the flue gases as a percentage of the heat input in a heating system can be estimated by using Figure 1. Exhaust gas loss or waste heat depends on flue gas temperature and its mass flow, or in practical terms, excess air resulting from combustion air supply and air leakage into the furnace. The excess air can be estimated by measuring oxygen percentage in the flue gases.

Engineering Development of Coal-Fired High-Performance Power Systems  

Science Conference Proceedings (OSTI)

A High Performance Power System (HIPPS) is being developed. This system is a coal-fired, combined cycle plant with indirect heating of gas turbine air. Foster Wheeler Development Corporation and a team consisting of Foster Wheeler Energy Corporation, Bechtel Corporation, University of Tennessee Space Institute and Westinghouse Electric Corporation are developing this system. In Phase 1 of the project, a conceptual design of a commercial plant was developed. Technical and economic analyses indicated that the plant would meet the goals of the project which include a 47 percent efficiency (HHV) and a 10 percent lower cost of electricity than an equivalent size PC plant. The concept uses a pyrolysis process to convert coal into fuel gas and char. The char is fired in a High Temperature Advanced Furnace (HITAF). The HITAF is a pulverized fuel-fired boiler/air heater where steam is generated and gas turbine air is indirectly heated. The fuel gas generated in the pyrolyzer is then used to heat the gas turbine air further before it enters the gas turbine. The project is currently in Phase 2 which includes engineering analysis, laboratory testing and pilot plant testing. Research and development is being done on the HIPPS systems that are not commercial or being developed on other projects. Pilot plant testing of the pyrolyzer subsystem and the char combustion subsystem are being done separately. This report addresses the areas of technical progress for this quarter. The detail of syngas cooler design is given in this report. The final construction work of the CFB pyrolyzer pilot plant has started during this quarter. No experimental testing was performed during this quarter. The proposed test matrix for the future CFB pyrolyzer tests is given in this report. Besides testing various fuels, bed temperature will be the primary test parameter.

Measurement of air toxic emissions from a coal-fired boiler equipped with a tangentially-fired low NOx combustion system  

Science Conference Proceedings (OSTI)

This paper presents the results of measurements of chemical emissions from a coal-burning, tangentially-fired, utility boiler equipped with a hot-side electrostatic precipitator and a low NOx firing system. The tests were conducted in response to Title III of the 1990 Amendments to the Clean Air Act which lists 189 chemicals to be evaluated as {open_quotes}Air Toxics.{close_quotes} The project was jointly funded by the Electric Power Research Institute and the US Department of Energy under an existing Innovative Clean Coal Technology Cooperative Agreement managed by Southern Company Services. Field chemical emissions monitoring was conducted in two phases: a baseline {open_quotes}pre-low NOx burner{close_quotes} condition in September 1991 and in the LNCFS Level III low NOx firing condition in January 1992. In addition to stack emissions measurements of both organic and inorganic chemicals, plant material balance evaluations were performed to determine the efficiency of the hot-side ESP at controlling emissions of air toxics and to determine the fate of the target chemicals in various plant process streams.

Assembly and Characterization of a Prototype Laser-Optical Firing System  

Science Conference Proceedings (OSTI)

The design, assembly and characterization of the latest generation of a small, ruggedized laser-optical firing system will be discussed. This work builds upon earlier results in an effort to continue the development of robust fiber-coupled laseroptical firing systems.[1][2] This newest prototype strives to improve on earlier designs, while continuing to utilize many of the environmentally proven opto-mechanical sub-assemblies.[2][3] One area of improvement involves the implementation of a second optical safing and arming component. Several additional design improvements were also incorporated to address shortcomings uncovered during environmental testing.[4][5] These tests and the subsequent failure analysis were performed at the laser sub-system level. Four identical prototypes were assembled and characterized. The performance of the units were evaluated by comparing a number of parameters including laser output energy, slope efficiency, beam divergence, spatial intensity profile, fiber injection and splitter-coupler transmission efficiency. Other factors evaluated were the ease of alignment, repeatability of the alignment process and the fabrication of the fiberoptical cables. The experimentally obtained results will be compared and contrasted to the performance of earlier prototypes.

Engineering development of advanced coal-fired low emission boil systems. Quarterly technical progress report, October 1993--December 1993  

Science Conference Proceedings (OSTI)

The first test run of the Toroidal Vortex Combustor (TVC) was completed on December 6. Riley was unable to witness or set up independent sampling equipment for NO{sub x} and precursor measurement for this run. A second run which we witnessed, but did not sample, was completed December 17. This was conducted almost entirely near SR = 1.0 while Textron investigated temperature-load relationships to address concerns from Run 1. A third run was completed over the December holiday break on Dorchester coal to address concerns Textron had about the Illinois test coal. All subsequent tests will use the Illinois coal. Boiler, firing system design. Elevation drawings were developed for dry wall-fired, conventional U-fired slagging, and TVC fired slagging units. We are investigating the feasibility of modifying a conventional U-fired design for low-NOx operation as an alternative to the TVC. The approach taken to I date for NOx reduction in existing U-fired units is to retrofit with delayed-mixing burners with staging air at various places, similar to the approach with dry fired units. The concept of staged fuel addition or reburning for the U-fired system is being examined as a potential combustion NOx control approach. This concept has high potential due to the high temperature and long residence time available in the stagger. Some field trials with coke oven gas reburn produced very low NOx results. Modeling of this concept was identified as a priority task. The model development will include matching field data for air staging on slagging units to the predictions. Emissions control. Selection of an SO2 control process continues to be a high priority task. Sargent & Lundy completed a cost comparison of several regenerable processes, most of which have NOx control potential as well: Active coke, NOXSO, copper oxide, SNOX, ammonia (for SO only, ammonium sulfate byproduct), and a limestone scrubber for comparison.

An assessment of fire vulnerability for aged electrical relays  

SciTech Connect

There has been some concern that, as nuclear power plants age, protective measures taken to control and minimize the impact of fire may become ineffective, or significantly less effective, and hence result in an increased fire risk. One objective of the Fire Vulnerability of Aged Electrical Components Program is to assess the effects of aging and service wear on the fire vulnerability of electrical equipment. An increased fire vulnerability of components may lead to an overall increase in fire risk to the plant. Because of their widespread use in various electrical safety systems, electromechanical relays were chosen to be the initial components for evaluation. This test program assessed the impact of operational and thermal aging on the vulnerability of these relays to fire-induced damage. Only thermal effects of a fire were examined in this test program. The impact of smoke, corrosive materials, or fire suppression effects on relay performance were not addressed in this test program. The purpose of this test program was to assess whether the fire vulnerability of electrical relays increased with aging. The sequence followed for the test program was to: identify specific relay types, develop three fire scenarios, artificially age several relays, test the unaged and aged relays in the fire exposure scenarios, and compare the results. The relays tested were Agastat GPI, General Electric (GE) HMA, HGA, and HFA. At least two relays of each type were artificially aged and at least two relays of each type were new. Relays were operationally aged by cycling the relay under rated load for 2,000 operations. These relays were then thermally aged for 60 days with their coil energized.

The facility is equipped with a gas turbine and a topping combustor, and as such, will provide an opportunity to evaluate integrated pyrolyzer and turbine operation. This report addresses the areas of technical progress for this quarter. Detailed design of the components to be used to for the circulating bed gasification tests is underway. The circulating fluidized bed will allow for easy scale-up to larger size plants. The existing pyrolyzer will be outfitted with a cyclone and a j-valve to capture and reinject char into the lower combustion zone. Additional development work has been performed to evaluate advanced cycles utilizing the HIPPS system concept.

The objective of this analysis is to determine if ventilation ductwork in Building 776/777 will maintain their structural integrity during expected fire conditions as well as standard design fires typically used to ascertain fire resistance ratings. If the analysis shows that ductwork will not maintain structural integrity, the impact of this failure will be determined and analyzed, and alternative solutions recommended. Associated with this analysis is the development of a computer fire model which can be used as an engineering tool in analyzing the effect of fires on ductwork in other areas and buildings.

Multivent effects in a large scale boiling water reactor pressure suppression system  

Science Conference Proceedings (OSTI)

The steam-driven GKSS pressure suppression test facility, which contains 3 full scale vent pipes, has been used for 5 years to investigate the postulated loss-of-coolant accident in a Mark II and Type 69 boiling water reactor. Using the results from several of these tests, wetwell boundary load data (peak pressures and spectral power) during the chugging stage, have been evaluated for sparse pool response (one and two vents in the three vent pool) and for full pool response (one, two, or three vent operation in pools of constant wetwell pool area per vent). The sparse pool results indicate the pool-system, chug event boundary loads are strongly dependent on wetwell pool area per vent, with the load increasing with decreasing area. The full pool results show a substantial increase in the pool-system, chug event boundary loads upon a change from single cell to double cell operation; only minor change occurs in going from double to triple cell operation.

Development of a high-performance coal-fired power generating system with pyrolysis gas and char-fired high-temperature furnace (HITAF): Volume 4. Final report  

Science Conference Proceedings (OSTI)

An outgrowth of our studies of the FWDC coal-fired high performance power systems (HIPPS) concept was the development of a concept for the repowering of existing boilers. The initial analysis of this concept indicates that it will be both technically and economically viable. A unique feature of our greenfields HIPPS concept is that it integrates the operation of a pressurized pyrolyzer and a pulverized fuel-fired boiler/air heater. Once this type of operation is achieved, there are a few different applications of this core technology. Two greenfields plant options are the base case plant and a plant where ceramic air heaters are used to extend the limit of air heating in the HITAF. The greenfields designs can be used for repowering in the conventional sense which involves replacing almost everything in the plant except the steam turbine and accessories. Another option is to keep the existing boiler and add a pyrolyzer and gas turbine to the plant. The study was done on an Eastern utility plant. The owner is currently considering replacing two units with atmospheric fluidized bed boilers, but is interested in a comparison with HIPPS technology. After repowering, the emissions levels need to be 0.25 lb SO{sub x}/MMBtu and 0.15 lb NO{sub x}/MMBtu.

Estimation of radiative properties and temperature distributions in coal-fired boiler furnaces by a portable image processing system  

Science Conference Proceedings (OSTI)

This paper presented an experimental investigation on the estimation of radiative properties and temperature distributions in a 670 t/h coal-fired boiler furnace by a portable imaging processing system. The portable system has been calibrated by a blackbody furnace. Flame temperatures and emissivities were measured by the portable system and equivalent blackbody temperatures were deduced. Comparing the equivalent blackbody temperatures measured by the portable system and the infrared pyrometer, the relative difference is less than 4%. The reconstructed pseudo-instantaneous 2-D temperature distributions in two cross-sections can disclose the combustion status inside the furnace. The measured radiative properties of particles in the furnace proved there is significant scattering in coal-fired boiler furnaces and it can provide useful information for the calculation of radiative heat transfer and numerical simulation of combustion in coal-fired boiler furnaces. The preliminary experimental results show this technology will be helpful for the combustion diagnosis in coal-fired boiler furnaces. (author)

Development and Testing of Industrial Scale Coal Fired Combustion System, Phase 3  

SciTech Connect

Coal Tech Corp's mission is to develop, license & sell innovative, lowest cost, solid fuel fired power systems & total emission control processes using proprietary and patented technology for domestic and international markets. The present project 'DEVELOPMENT & TESTING OF INDUSTRIAL SCALE, COAL FIRED COMBUSTION SYSTEM, PHASE 3' on DOE Contract DE-AC22-91PC91162 was a key element in achieving this objective. The project consisted of five tasks that were divided into three phases. The first phase, 'Optimization of First Generation 20 MMBtu/hr Air-Cooled Slagging Coal Tech Combustor', consisted of three tasks, which are detailed in Appendix 'A' of this report. They were implemented in 1992 and 1993 at the first generation, 20 MMBtu/hour, combustor-boiler test site in Williamsport, PA. It consisted of substantial combustor modifications and coal-fired tests designed to improve the combustor's wall cooling, slag and ash management, automating of its operation, and correcting severe deficiencies in the coal feeding to the combustor. The need for these changes was indicated during the prior 900-hour test effort on this combustor that was conducted as part of the DOE Clean Coal Program. A combination of combustor changes, auxiliary equipment changes, sophisticated multi-dimensional combustion analysis, computer controlled automation, and series of single and double day shift tests totaling about 300 hours, either resolved these operational issues or indicated that further corrective changes were needed in the combustor design. The key result from both analyses and tests was that the combustor must be substantially lengthened to maximize combustion efficiency and sharply increase slag retention in the combustor. A measure of the success of these modifications was realized in the third phase of this project, consisting of task 5 entitled: 'Site Demonstration with the Second Generation 20 MMBtu/hr Air-Cooled Slagging Coal Tech Combustor'. The details of the task 5 effort are contained in Appendix 'C'. It was implemented between 1994 and 1998 after the entire 20 MMBtu/hr combustor-boiler facility was relocated to Philadelphia, PA in 1994. A new test facility was designed and installed. A substantially longer combustor was fabricated. Although not in the project plan or cost plan, an entire steam turbine-electric power generating plant was designed and the appropriate new and used equipment for continuous operation was specified. Insufficient funds and the lack of a customer for any electric power that the test facility could have generated prevented the installation of the power generating equipment needed for continuous operation. All other task 5 project measures were met and exceeded. 107 days of testing in task 5, which exceeded the 63 days (about 500 hours) in the test plan, were implemented. Compared to the first generation 20 MMBtu/hr combustor in Williamsport, the 2nd generation combustor has a much higher combustion efficiency, the retention of slag inside the combustor doubled to about 75% of the coal ash, and the ash carryover into the boiler, a major problem in the Williamsport combustor was essentially eliminated. In addition, the project goals for coal-fired emissions were exceeded in task 5. SO{sub 2} was reduced by 80% to 0.2 lb/MMBtu in a combination of reagent injection in the combustion and post-combustion zones. NO{sub x} was reduced by 93% to 0.07 lb/MMBtu in a combination of staged combustion in the combustor and post-combustion reagent injection. A baghouse was installed that was rated to 0.03 lb/MMBtu stack particle emissions. The initial particle emission test by EPA Method 5 indicated substantially higher emissions far beyond that indicated by the clear emission plume. These emissions were attributed to steel particles released by wall corrosion in the baghouse, correction of which had no effect of emissions.

System Modeling of ORNL s 20 MW(t) Wood-fired Gasifying Boiler  

Science Conference Proceedings (OSTI)

We present an overview of the new 20 MW(t) wood-fired steam plant currently under construction by Johnson Controls, Inc. at the Oak Ridge National Laboratory in Tennessee. The new plant will utilize a low-temperature air-blown gasifier system developed by the Nexterra Systems Corporation to generate low-heating value syngas (producer gas), which will then be burned in a staged combustion chamber to produce heat for the boiler. This is considered a showcase project for demonstrating the benefits of clean, bio-based energy, and thus there is considerable interest in monitoring and modeling the energy efficiency and environmental footprint of this technology relative to conventional steam generation with petroleum-based fuels. In preparation for system startup in 2012, we are developing steady-state and dynamic models of the major process components, including the gasifiers and combustor. These tools are intended to assist in tracking and optimizing system performance and for carrying out future conceptual studies of process changes that might improve the overall energy efficiency and sustainability. In this paper we describe the status of our steady-state gasifier and combustor models and illustrate preliminary results from limited parametric studies.

EVALUATION OF MERCURY EMISSIONS FROM COAL-FIRED FACILITIES WITH SCR AND FGD SYSTEMS  

Science Conference Proceedings (OSTI)

CONSOL Energy Inc., Research & Development (CONSOL), with support from the U.S. Department of Energy, National Energy Technology Laboratory (DOE) is evaluating the effects of selective catalytic reduction (SCR) on mercury (Hg) capture in coal-fired plants equipped with an electrostatic precipitator (ESP) - wet flue gas desulfurization (FGD) combination or a spray dyer absorber--fabric filter (SDA-FF) combination. In this program CONSOL is determining mercury speciation and removal at 10 coal-fired facilities. The objectives are (1) to evaluate the effect of SCR on mercury capture in the ESP-FGD and SDA-FF combinations at coal-fired power plants, (2) evaluate the effect of catalyst degradation on mercury capture; (3) evaluate the effect of low load operation on mercury capture in an SCR-FGD system, and (4) collect data that could provide the basis for fundamental scientific insights into the nature of mercury chemistry in flue gas, the catalytic effect of SCR systems on Hg speciation and the efficacy of different FGD technologies for Hg capture. This document, the second in a series of topical reports, describes the results and analysis of mercury sampling performed on a 330 MW unit burning a bituminous coal containing 1.0% sulfur. The unit is equipped with a SCR system for NOx control and a spray dryer absorber for SO{sub 2} control followed by a baghouse unit for particulate emissions control. Four sampling tests were performed in March 2003. Flue gas mercury speciation and concentrations were determined at the SCR inlet, air heater outlet (ESP inlet), and at the stack (FGD outlet) using the Ontario Hydro method. Process stream samples for a mercury balance were collected to coincide with the flue gas measurements. Due to mechanical problems with the boiler feed water pumps, the actual gross output was between 195 and 221 MW during the tests. The results showed that the SCR/air heater combination oxidized nearly 95% of the elemental mercury. Mercury removal, on a coal-to-stack basis, was 87%. The mercury material balance closures for the four tests conducted at the plant ranged from 89% to 114%, with an average of 100%. These results appear to show that the SCR had a positive effect on mercury removal. In earlier programs, CONSOL sampled mercury at six plants with wet FGDs for SO{sub 2} control without SCR catalysts. At those plants, an average of 61 {+-} 15% of the mercury was in the oxidized form at the air heater outlet. The principal purpose of this work is to develop a better understanding of the potential Hg removal ''co-benefits'' achieved by NOx, and SO{sub 2} control technologies. It is expected that this data will provide the basis for fundamental scientific insights into the nature of Hg chemistry in flue gas, the catalytic effect of SCR systems on Hg speciation and the efficacy of different FGD technologies for Hg capture. Ultimately, this insight could help to design and operate SCR and FGD systems to maximize Hg removal.

This document, the ninth in a series of topical reports, describes the results and analysis of mercury sampling performed on Unit 1 at Plant 7, a 566 MW unit burning a bituminous coal containing 3.6% sulfur. The unit is equipped with a SCR, ESP, and wet FGD to control NO{sub x}, particulate, and SO{sub 2} emissions, respectively. Four sampling tests were performed in August 2004 during ozone season with the SCR operating; flue gas mercury speciation and concentrations were determined at the SCR inlet, SCR outlet, air heater outlet (ESP inlet), ESP outlet (FGD inlet), and at the stack (FGD outlet) using the Ontario Hydro method. Three sampling tests were also performed in November 2004 during non-ozone season with the SCR bypassed; flue gas mercury speciation and concentrations were determined at the ESP outlet (FGD inlet), and at the stack (FGD outlet). Process samples for material balances were collected during the flue gas measurements. The results show that, at the point where the flue gas enters the FGD, a greater percentage of the mercury was in the oxidized form when the SCR was operating compared to when the SCR was bypassed (97% vs 91%). This higher level of oxidation resulted in higher mercury removals in the FGD because the FGD removed 90-94% of the oxidized mercury in both cases. Total coal-to-stack mercury removal was 86% with the SCR operating, and 73% with the SCR bypassed. The average mercury mass balance closure was 81% during the ozone season tests and 87% during the non-ozone season tests.

EVALUATION OF MERCURY EMISSIONS FROM COAL-FIRED FACILITIES WITH SCR AND FGD SYSTEMS

This document, the seventh in a series of topical reports, describes the results and analysis of mercury sampling performed on a 1,300 MW unit burning a bituminous coal containing three percent sulfur. The unit was equipped with an ESP and a limestone-based wet FGD to control particulate and SO2 emissions, respectively. At the time of sampling an SCR was not installed on this unit. Four sampling tests were performed in September 2003. Flue gas mercury speciation and concentrations were determined at the ESP outlet (FGD inlet), and at the stack (FGD outlet) using the Ontario Hydro method. Process stream samples for a mercury balance were collected to coincide with the flue gas measurements. The results show that the FGD inlet flue gas oxidized:elemental mercury ratio was roughly 2:1, with 66% oxidized mercury and 34% elemental mercury. Mercury removal, on a coal-to-stack basis, was 53%. The average Hg concentration in the stack flue gas was 4.09 {micro}g/m{sup 3}. The average stack mercury emission was 3.47 Ib/TBtu. The mercury material balance closures ranged from 87% to 108%, with an average of 97%. A sampling program similar to this one was performed on a similar unit (at the same plant) that was equipped with an SCR for NOx control. Comparison of the results from the two units show that the SCR increases the percentage of mercury that is in the oxidized form, which, in turn, lends to more of the total mercury being removed in the wet scrubber. The principal purpose of this work is to develop a better understanding of the potential mercury removal ''co-benefits'' achieved by NOx, and SO{sub 2} control technologies. It is expected that this data will provide the basis for fundamental scientific insights into the nature of mercury chemistry in flue gas, the catalytic effect of SCR systems on mercury speciation and the efficacy of different FGD technologies for mercury capture. Ultimately, this insight could help to design and operate SCR and FGD systems to maximize mercury removal.

This document, the tenth in a series of topical reports, describes the results and analysis of mercury sampling performed on two 468 MW units burning bituminous coal containing 1.3-1.7% sulfur. Unit 2 is equipped with an SCR, ESP, and wet FGD to control NO{sub x}, particulate, and SO{sub 2} emissions, respectively. Unit 1 is similar to Unit 2, except that Unit 1 has no SCR for NOx control. Four sampling tests were performed on both units in January 2005; flue gas mercury speciation and concentrations were determined at the economizer outlet, air heater outlet (ESP inlet), ESP outlet (FGD inlet), and at the stack (FGD outlet) using the Ontario Hydro method. Process samples for material balances were collected with the flue gas measurements. The results show that the SCR increased the oxidation of the mercury at the air heater outlet. At the exit of the air heater, a greater percentage of the mercury was in the oxidized and particulate forms on the unit equipped with an SCR compared to the unit without an SCR (97.4% vs 91%). This higher level of oxidation resulted in higher mercury removals in the scrubber. Total mercury removal averaged 97% on the unit with the SCR, and 87% on the unit without the SCR. The average mercury mass balance closure was 84% on Unit 1 and 103% on Unit 2.

Optically powered firing system for the Procyon high explosive pulse power system  

DOE Green Energy (OSTI)

An optically powered fireset has been developed for the Procyon high explosive pulsed-power generator at Los Alamos National Laboratory. The fireset was located inside this flux compression experiment where large magnetic fields are generated. No energy sources were allowed inside the experiment and no wire connections can penetrate through the wall, of the experiment because of the high magnetic fields. The flux compression was achieved with high explosives in the experiment. The fireset was used to remotely charge a 1.2 {micro}f capacitor to 6,500V and to provide a readout of the voltage on the capacitor at the control room. The capacitor was charged by using two 7W fiber coupled GaAlAs laser diodes to illuminate two fiber coupled 12V solar cells. The solar cell outputs were connected in parallel to the input of a DC-DC converter which step up a 12V to 6,500V. A voltmeter, powered by illuminating a third 12V solar cell with 1W laser diode, was used to monitor the charge on the capacitor. The voltage was measured with a divider circuit, then converted to frequency in a V-F converter and transmitted to the control room over a fiber optic link. A fiducial circuit measured the capacitor firing current and provided an optical output timing pulse.

Alternative approach for fire supression of class A, B and C fires in gloveboxes  

SciTech Connect

Department of Energy (DOE) Orders and National Fire Protection Association (NFPA) Codes and Standards require fire suppression in gloveboxes. Several potential solutions have been and are currently being considered at Los Alamos National Laboratory (LANL). The objective is to provide reliable, minimally invasive, and seismically robust fire suppression capable of extinguishing Class A, B, and C fires; achieve compliance with DOE and NFPA requirements; and provide value-added improvements to fire safety in gloveboxes. This report provides a brief summary of current approaches and also documents the successful fire tests conducted to prove that one approach, specifically Fire Foe{trademark} tubes, is capable of achieving the requirement to provide reliable fire protection in gloveboxes in a cost-effective manner.

Multiplexed Optical Fiber Sensors for Coal Fired Advanced Fossil Energy Systems  

Science Conference Proceedings (OSTI)

This report summarizes technical progress on the program ??Multiplexed Optical Fiber Sensors for Coal Fired Advanced Fossil Energy Systems? funded by the National Energy Technology Laboratory of the U.S. Department of Energy, and performed jointly by the Center for Photonics Technology of the Bradley Department of Electrical and Computer Engineering and the Department of Materials Science and Engineering at Virginia Tech. This three-year project started on October 1, 2008. In the project, a fiber optical sensing system based on intrinsic Fabry-Perot Interferometer (IFPI) was developed for strain and temperature measurements for Ultra Supercritical boiler condition assessment. Investigations were focused on sensor design, fabrication, attachment techniques and novel materials for high temperature and strain measurements. At the start of the project, the technical requirements for the sensing technology were determined together with our industrial partner Alstom Power. As is demonstrated in Chapter 4, all the technical requirements are successfully met. The success of the technology extended beyond laboratory test; its capability was further validated through the field test at DOE NETL, in which the sensors yielded distributed temperature mapping of a testing coupon installed in the turbine test rig. The measurement results agreed well with prior results generated with thermocouples. In this project, significant improvements were made to the IFPI sensor technology by splicing condition optimization, transmission loss reduction, sensor signal demodulation and sensor system design.

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

SciTech Connect

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

Engineering development of coal-fired high-performance power systems. Progress report, April 1--June 30, 1996  

SciTech Connect

In Phase 1 of the project, a conceptual design of a coal-fired, high-performance power system (HIPPS) was developed, and small-scale R and D was done in critical areas of the design. The current phase of the project includes development through the pilot plant stage and design of a prototype plant that would be built in Phase 3. The power-generating system being developed in this project will be an improvement over current coal-fired systems. It is a combined-cycle plant. This arrangement is referred to as the All Coal HIPPS because it does not require any other fuels for normal operation. A fluidized bed, air-blown pyrolyzer converts coal into fuel gas and char. The char is fired in a high-temperature advanced furnace (HITAF) which heats both air for a gas turbine and steam for a steam turbine. The fuel gas from the pyrolyzer goes to a topping combustor where it is used to raise the air entering the gas turbine to 1288 C. In addition to the HITAF, steam duty is achieved with a heat-recovery steam generator (HRSG) in the gas turbine exhaust stream and economizers in the HITAF flue gas exhaust stream. Progress during the quarter is described.

Development of a high-performance coal-fired power generating system with pyrolysis gas and char-fired high temperature furnace (HITAF). Quarterly progress report No. 3, July--September 1992  

SciTech Connect

A concept for an advanced coal-fired combined-cycle power generating system is currently being developed. The first phase of this three-phase program consists of conducting the necessary research and development to define the system, evaluate the economic and technical feasibility of the concept, and prepare an R & D plan to develop the concept further. Foster Wheeler Development Corporation is leading a team ofcompanies involved in this effort. The system proposed to meet these goals is a combined-cycle system where air for a gas turbine is indirectly heated to approximately 1800{degrees}F in furnaces fired with cool-derived fuels and then directly heated in a natural-gas-fired combustor up to about 2400{degrees}F. The system is based on a pyrolyzing process that converts the coal into a low-Btu fuel gas and char. The fuelgas is a relatively clean fuel, and it is fired to heat tube surfaces that are susceptible to corrosion and problems from ash deposition. In particular, the high-temperature air heater tubes, which will need tobe a ceramic material, will be located in a separate furnace or region of a furnace that is exposed to combustion products from the low-Btu fuel gas only. A simplified process flow diagram is shown.

EVALUATION OF MERCURY EMISSIONS FROM COAL-FIRED FACILITIES WITH SCR AND FGD SYSTEMS  

Science Conference Proceedings (OSTI)

CONSOL Energy Inc., Research & Development (CONSOL), with support from the U.S. Department of Energy, National Energy Technology Laboratory (DOE) and the Electric Power Research Institute (EPRI), evaluated the effects of selective catalytic reduction (SCR) on mercury (Hg) capture in coal-fired plants equipped with an electrostatic precipitator (ESP)-wet flue gas desulfurization (FGD) combination or a spray dyer absorber-fabric filter (SDA-FF) combination. In this program CONSOL determined mercury speciation and removal at 10 bituminous coal-fired facilities; at four of these facilities, additional tests were performed on units without SCR, or with the existing SCR bypassed. This project final report summarizes the results and discusses the findings of the body of work as a whole. Eleven Topical Reports were issued (prior to this report) that describe in great detail the sampling results at each of the ten power plants individually. The results showed that the SCR-FGD combination removed a substantial fraction of mercury from flue gas. The coal-to-stack mercury removals ranged from 65% to 97% for the units with SCR and from 53% to 87% for the units without SCR. There was no indication that any type of FGD system was more effective at mercury removal than others. The coal-to-stack mercury removal and the removal in the wet scrubber were both negatively correlated with the elemental mercury content of the flue gas and positively correlated with the scrubber liquid chloride concentration. The coal chlorine content was not a statistically significant factor in either case. Mercury removal in the ESP was positively correlated with the fly ash carbon content and negatively correlated with the flue gas temperature. At most of the units, a substantial fraction (>35%) of the flue gas mercury was in the elemental form at the boiler economizer outlet. After passing through the SCR-air heater combination very little of the total mercury (<10%) remained in the elemental form in the flue gas; this was true for all SCR catalyst types and sources. Although chlorine has been suggested as a factor affecting the mercury speciation in flue gas, coal chlorine was not a statistically significant factor affecting mercury speciation at the economizer exit or at the air heater exit. The only statistically significant factors were the coal ash CaO content and the fly ash carbon content; the fraction of mercury in the elemental form at the economizer exit was positively correlated with both factors. In a direct comparison at four SCR-equipped units vs. similar units at the same sites without SCR (or with the SCR bypassed), the elemental mercury fractions (measured at the ESP outlet) were lower, and the coal-to-stack mercury removals were higher, when the SCR was present and operating. The average coal-to-stack mercury removal at the four units without an operating SCR was 72%, whereas the average removal at the same sites with operating SCRs was 88%. The unit mercury mass balance (a gauge of the overall quality of the tests) at all of the units ranged from 81% to 113%, which were within our QA/QC criterion of 80-120%.

Conceptual design of a coal-fired MHD retrofit plant. Topical report, Seed Regeneration System Study 2  

SciTech Connect

Westinghouse Advanced Energy Systems (WAES), through Contract No. DE-AC22-87PC79668 funded by US DOE/PETC, is conducting a conceptual design study to evaluate a coal-fired magnetohydrodynamic (MHD) retrofit of a utility plant of sufficient size to demonstrate the technical and future economic viability of an MHD system operating within an electric utility environment. The objective of this topical report is to document continuing seed regeneration system application studies and the definition of will system integration requirements for the Scholz MHD retrofit plant design. MHD power plants require the addition of a seeding material in the form of potassium to enhance the ionization of the high temperature combustion gas in the MHD channel. This process has an added environmental advantage compared to other types of coal-fired power plants in that the potassium combines with the naturally occurring sulfur in the coal to form a potassium sulfate flyash (K{sub 2}SO{sub 4}) which can be removed from the process by appropriate particulate control equipment. Up to 100% of the Sulfur in the coal can be removed by this process thereby providing environmentally clean power plant operation that is better than required by present and anticipated future New Source Performance Standards (NSPS).

DOE prepared an environmental assessment (EA)for wildland fire management activities on the Idaho National Engineering and Environmental Laboratory (INEEL) (DOE/EA-1372). The EA was developed to evaluate wildland fire management options for pre-fire, fire suppression, and post fire activities. Those activities have an important role in minimizing the conversion of the native sagebrush steppe ecosystem found on the INEEL to non-native weeds. Four alternative management approaches were analyzed: Alternative 1 - maximum fire protection; Alternative 2 - balanced fire protection; Alternative 2 - balanced fire protection; Alternative 3 - protect infrastructure and personnel; and Alternative 4 - no action/traditional fire protection.

Development of a high-performance coal-fired power generating system with pyrolysis gas and char-fired high temperature furnace (HITAF). Progress report No. 12, September--December 1994  

SciTech Connect

A concept for an advanced coal-fired combined-cycle power generating system is currently being developed. The first phase of this three-phase program consists of conducting the necessary research and development to define the system, evaluating the economic and technical feasibility of the concept, and preparing an R&D plan to develop the concept further. There are two basic arrangements of our HIPPS cycle. Both are coal-fired combined cycles. One arrangement is the 35% natural gas HIPPS. Coal is converted to fuel gas and char in a pyrolysis process, and these fuels are fired in separate parts of a high temperature advanced furnace (HITAF). The char-fired furnace produces flue gas that is used to heat gas turbine air up to 1400 F. Alloy tubes are used for these tube banks. After leaving the alloy tube banks, the gas turbine air goes through a ceramic air heater where it is heated from 1400 F to 1800 F. The flue gas that goes through the ceramic air heater comes from the combustion of the fuel gas that is produced in the pyrolysis process. This fuel gas is cleaned to remove particulates and alkalies that would corrode and plug a ceramic air heater. The air leaving the ceramic air heater needs to be heated further to achieve the efficiency goal of 47%, and this is done by firing natural gas in the gas turbine combustor. An alternative arrangement of the HIPPS cycle is called the All Coal HIPPS. With this arrangement, the char is used to heat the gas turbine air to 1400 F as before, but instead of then going to a ceramic air heater, the air goes directly to the gas turbine combustor. The fuel gas generated in the pyrolyzer is used as fuel in the gas turbine combustor. In both cycle arrangements, heat is transferred to the steam cycle in the HITAF and a heat recovery steam generator (HRSG).

E-Print Network (OSTI)

A thermal balance mathematics model of a manufactured space with a gas-fired radiant heating system is established to calculate the heating load. Computer programs are used to solve the model. Envelope internal surface temperatures under different outdoor temperatures are obtained, and the heating load of the manufactured space is analyzed. The relationship between the envelope internal surface temperature and the workspace temperature is also analyzed in this paper. CFD simulation software is used to simulate the temperature field and the envelope's internal surface temperature of the manufacture space with hot-air heating system. Comparison and analysis of heating loads are done between the manufactured spaces with convection heating and radiant heating systems.

Fuel supply system and method for coal-fired prime mover  

DOE Patents (OSTI)

A coal-fired gas turbine engine is provided with an on-site coal preparation and engine feeding arrangement. With this arrangement, relatively large dry particles of coal from an on-site coal supply are micro-pulverized and the resulting dry, micron-sized, coal particulates are conveyed by steam or air into the combustion chamber of the engine. Thermal energy introduced into the coal particulates during the micro-pulverizing step is substantially recovered since the so-heated coal particulates are fed directly from the micro-pulverizer into the combustion chamber.

Gas-fired desiccant dehumidification system field evaluation in a quick-service restaurant. Final report, October 1989  

Science Conference Proceedings (OSTI)

This report describes the results of a field evaluation of state-of-art desiccant dehumidification equipment in Houston, TX. The evaluation demonstrated that comfort control in a quick-service restaurant could be improved dramatically. However, available gas-fired desiccant dehumidification equipment is too expensive, inefficient, and unreliable to be considered for wide application in the restaurant industry. Results of a technical and economic analysis of four HVAC options in four U.S. cities indicated that improved comfort control could be achieved with only a modest increase in operating costs with an advanced system. This, coupled with the economic benefits achieved through lower indoor humidity such as improved crew performance and reduced maintenance costs, could justify the introduction of an advanced, integrated, HVAC system using desiccant technology which has an installed cost similar to current equipment.

Enhancing Carbon Reactivity in Mercury Control in Lignite-Fired Systems  

Science Conference Proceedings (OSTI)

This project was awarded through the U.S. Department of Energy (DOE) National Energy Technology Laboratory Program Solicitation DE-PS26-03NT41718-01. The Energy & Environmental Research Center (EERC) led a consortium-based effort to resolve mercury (Hg) control issues facing the lignite industry. The EERC team-the Electric Power Research Institute (EPRI); the URS Corporation; the Babcock & Wilcox Company; ADA-ES; Apogee; Basin Electric Power Cooperative; Otter Tail Power Company; Great River Energy; Texas Utilities; Montana-Dakota Utilities Co.; Minnkota Power Cooperative, Inc.; BNI Coal Ltd.; Dakota Westmoreland Corporation; the North American Coal Corporation; SaskPower; and the North Dakota Industrial Commission-demonstrated technologies that substantially enhanced the effectiveness of carbon sorbents to remove Hg from western fuel combustion gases and achieve a high level ({ge} 55% Hg removal) of cost-effective control. The results of this effort are applicable to virtually all utilities burning lignite and subbituminous coals in the United States and Canada. The enhancement processes were previously proven in pilot-scale and limited full-scale tests. Additional optimization testing continues on these enhancements. These four units included three lignite-fired units: Leland Olds Station Unit 1 (LOS1) and Stanton Station Unit 10 (SS10) near Stanton and Antelope Valley Station Unit 1 (AVS1) near Beulah and a subbituminous Powder River Basin (PRB)-fired unit: Stanton Station Unit 1 (SS1). This project was one of three conducted by the consortium under the DOE mercury program to systematically test Hg control technologies available for utilities burning lignite. The overall objective of the three projects was to field-test and verify options that may be applied cost-effectively by the lignite industry to reduce Hg emissions. The EERC, URS, and other team members tested sorbent injection technologies for plants equipped with electrostatic precipitators (ESPs) and spray dryer absorbers combined with fabric filters (SDAs-FFs). The work focused on technology commercialization by involving industry and emphasizing the communication of results to vendors and utilities throughout the project.

No moving parts safe and arm apparatus and method with monitoring and built-in-test for optical firing of explosive systems  

DOE Patents (OSTI)

A laser initiated ordnance controller apparatus which provides a safe and arm scheme with no moving parts. The safe and arm apparatus provides isolation of firing energy to explosive devices using a combination of polarization isolation and control through acousto-optical deviation of laser energy pulses. The apparatus provides constant monitoring of the systems status and performs 100% built-in-test at any time prior to ordnance ignition without the risk of premature ignition or detonation. The apparatus has a computer controller, a solid state laser, an acousto-optic deflector and RF drive circuitry, built-in-test optics and electronics, and system monitoring capabilities. The optical system is completed from the laser beam power source to the pyrotechnic ordnance through fiber optic cabling, optical splitters and optical connectors. During operation of the apparatus, a command is provided by the computer controller and, simultaneous with laser flashlamp fire, the safe and arm device is opened for approximately 200 microseconds which allows the laser pulse to transmit through the device. The arm signal also energizes the laser power supply and activated the acousto-optical deflector. When the correct fire format command is received, the acousto-optic deflector moves to the selected event channel and the channel is verified to ensure the system is pointing to the correct position. Laser energy is transmitted through the fiber where an ignitor or detonator designed to be sensitive to optical pulses is fired at the end of the fiber channel.

A coal-fired combustion system for industrial process heating applications. Quarterly technical progress report, July 1993--September 1993  

SciTech Connect

This advanced combustion system research program is for the development of innovative coal-fired process heaters which can be used for high temperature melting, smelting and waste vitrification processes. The process heater systems to be developed have multiple use applications; however, the Phase 3 research effort is being focused on the development of a process heater system to be used for producing value added vitrified glass products from boiler/incinerator ashes and industrial wastes. The primary objective of the Phase 3 project is to develop and integrate all the system components, from fuel through total system controls, and then test the complete system in order to evaluate its potential marketability. During the past quarter, the major effort was completing some of the system modification installation designs, completing industry funded testing, developing a surrogate TSCA ash composition, and completing the TSCA ash Test Plan. The installation designs will be used for the equipment modifications planned for the end of CY 93. The industry funded testing consisted of vitrifying Spent Aluminum Potliner (SPL) which is a listed hazardous waste. This testing has verified that SPL can be vitrified into a safe, recyclable glass product. Some results from this testing are provided in Section 2.2.1. The surrogate TSCA ash composition was developed with input from various DOE laboratories and subcontractors. The surrogate ash consists of a mixture of MSW fly ash and bottom ash spiked with heavy metal contaminants. The levels of metal additives are sufficient to ascertain the partitioning of the contaminants between the glass and effluent flow streams. Details of the surrogate composition and the planned testing is provided in Section 4.2.2.

Advanced Turbine Systems Program conceptual design and product development. Task 3.0, Selection of natural gas-fired Advanced Turbine System  

DOE Green Energy (OSTI)

This report presents results of Task 3 of the Westinghouse ATS Phase II program. Objective of Task 3 was to analyze and evaluate different cycles for the natural gas-fired Advanced Turbine Systems in order to select one that would achieve all ATS program goals. About 50 cycles (5 main types) were evaluated on basis of plant efficiency, emissions, cost of electricity, reliability-availability-maintainability (RAM), and program schedule requirements. The advanced combined cycle was selected for the ATS plant; it will incorporate an advanced gas turbine engine as well as improvements in the bottoming cycle and generator. Cost and RAM analyses were carried out on 6 selected cycle configurations and compared to the baseline plant. Issues critical to the Advanced Combined Cycle are discussed; achievement of plant efficiency and cost of electricity goals will require higher firing temperatures and minimized cooling of hot end components, necessitating new aloys/materials/coatings. Studies will be required in combustion, aerodynamic design, cooling design, leakage control, etc.

LARGE-SCALE MECURY CONTROL TECHNOLOGY TESTING FOR LIGNITE-FIRED UTILITIES-OXIDATION SYSTEMS FOR WET FGD  

SciTech Connect

The Energy & Environmental Research Center (EERC) is conducting a consortium-based effort directed toward resolving the mercury (Hg) control issues facing the lignite industry. Specifically, the EERC team--the EERC, EPRI, URS, ADA-ES, Babcock & Wilcox, the North Dakota Industrial Commission, SaskPower, and the Mercury Task Force, which includes Basin Electric Power Cooperative, Otter Tail Power Company, Great River Energy, Texas Utilities (TXU), Montana-Dakota Utilities Co., Minnkota Power Cooperative, BNI Coal Ltd., Dakota Westmoreland Corporation, and the North American Coal Company--has undertaken a project to significantly and cost-effectively oxidize elemental mercury in lignite combustion gases, followed by capture in a wet scrubber. This approach will be applicable to virtually every lignite utility in the United States and Canada and potentially impact subbituminous utilities. The oxidation process is proven at the pilot-scale and in short-term full-scale tests. Additional optimization is continuing on oxidation technologies, and this project focuses on longer-term full-scale testing. The lignite industry has been proactive in advancing the understanding of and identifying control options for Hg in lignite combustion flue gases. Approximately 1 year ago, the EERC and EPRI began a series of Hg-related discussions with the Mercury Task Force as well as utilities firing Texas and Saskatchewan lignites. This project is one of three being undertaken by the consortium to perform large-scale Hg control technology testing to address the specific needs and challenges to be met in controlling Hg from lignite-fired power plants. This project involves Hg oxidation upstream of a system equipped with an electrostatic precipitator (ESP) followed by wet flue gas desulfurization (FGD). The team involved in conducting the technical aspects of the project includes the EERC, Babcock & Wilcox, URS, and ADA-ES. The host sites include Minnkota Power Cooperative Milton R. Young Unit 2 and TXU Monticello Unit 3. The work involves establishing Hg oxidation levels upstream of air pollution control devices (APCDs) and removal rates across existing ESP and FGD units, determining costs associated with those removal rates, investigating the possibility of the APCD acting as a multipollutant control device, quantifying the balance of plant impacts of the control technologies, and facilitating technology commercialization.

Test Plan to Assess Fire Effects on the Function of an Engineered Surface Barrier  

Science Conference Proceedings (OSTI)

Wildfire is a frequent perturbation in shrub steppe ecosystems, altering the flora, fauna, atmosphere, and soil of these systems. Research on the fire effects has focused mostly on natural ecosystems with essentially no attention on engineered systems like surface barriers. The scope of the project is to use a simulated wildfire to induce changes in an engineered surface barrier and document the effects on barrier performance. The main objective is to quantify the effects of burning and the resulting post-fire conditions on alterations in soil physical properties; hydrologic response, particularly the water balance; geochemical properties; and biological properties. A secondary objective is to use the lessons learned to maximize fire protection in the design of long-term monitoring systems based on electronic sensors. A simulated wildfire will be initiated, controlled and monitored at the 200-BP-1 barrier in collaboration with the Hanford Fire Department during the fall of 2008. The north half of the barrier will be divided into nine 12 x 12 m plots, each of which will be randomly assigned a fuel load of 2 kg m-2 or 4 kg m-2. Each plot will be ignited around the perimeter and flames allowed to carry to the centre. Any remaining unburned vegetation will be manually burned off using a drip torch. Progress of the fire and its effects will be monitored using point measurements of thermal, hydrologic, and biotic variables. Three measures of fire intensity will be used to characterize fire behavior: (1) flame height, (2) the maximum temperature at three vertical profile levels, and (3) total duration of elevated temperature at these levels. Pre-burn plant information, including species diversity, plant height, and canopy diameter will be measured on shrubs from the plots to be burned and from control plots at the McGee ranch. General assessments of shrub survival, recovery, and recruitment will be made after the fire. Near-surface soil samples will be collected pre- and post-burn to determine changes in the gravel content of the surface layer so as to quantify inflationary or deflationary responses to fire and to reveal the ability of the surface to resist post-fire erosive stresses. Measures of bulk density, water repellency, water retention, and hydraulic conductivity will be used to characterize changes in infiltration rates and water storage capacity following the fire. Samples will also be analyzed to quantify geochemical changes including changes in soil pH, cation exchange capacity, specific surface area, and the concentration of macro nutrients (e.g. N, P, K) and other elements such as Na, Mg, Ca, that are critical to the post-fire recovery revegetation. Soil CO2 emissions will be measured monthly for one year following the burn to document post-fire stimulation of carbon turnover and soil biogenic emissions. Surface and subsurface temperature measurements at and near monitoring installations will be used to document fire effects on electronic equipment. The results of this study will be used to bridge the gaps in knowledge on the effects of fire on engineered ecosystems (e.g. surface barriers), particularly the hydrologic and biotic characteristics that govern the water and energy balance. These results will also support the development of practical fire management techniques for barriers that are compatible with wildfire suppression strategies. Furthermore, lessons learned will be use to develop installation strategies needed to protect electronic monitoring equipment from the intense heat of fire and the potential damaging effects of smoke and fire extinguishing agents. Such information is needed to better understand long-term barrier performance under extreme conditions, especially if site maintenance and operational funding is lost for activities such as barrier revegetation.

No moving parts safe & arm apparatus and method with monitoring and built-in-test for optical firing of explosive systems  

DOE Patents (OSTI)

A laser initiated ordnance controller apparatus which provides a safe and arm scheme with no moving parts. The safe & arm apparatus provides isolation of firing energy to explosive devices using a combination of polarization isolation and control through acousto-optical deviation of laser energy pulses. The apparatus provides constant monitoring of the systems status and performs 100% built-in-test at any time prior to ordnance ignition without the risk of premature ignition or detonation. The apparatus has a computer controller, a solid state laser, an acousto-optic deflector and RF drive circuitry, built-in-test optics and electronics, and system monitoring capabilities. The optical system is completed from the laser beam power source to the pyrotechnic ordnance through fiber optic cabling, optical splitters and optical connectors. During operation of the apparatus, a command is provided by the computer controller and, simultaneous with laser flashlamp fire, the safe & arm device is opened for approximately 200 microseconds which allows the laser pulse to transmit through the device. The arm signal also energizes the laser power supply and activates the acousto-optical deflector. When the correct fire format command is received, the acousto-optic deflector moves to the selected event channel, and the channel is verified to ensure the system is pointing to the correct position. Laser energy is transmitted through the fiber where an ignitor or detonator designed to be sensitive to optical pulses is fired at the end of the fiber channel. Simultaneous event channels may also be utilized by optically splitting a single event channel. The built-in-test may be performed anytime prior to ordnance ignition. 6 figures.

Enhancements in Glovebox Design Resulting from Laboratory-Conducted FIre Tests  

SciTech Connect

The primary mission of the Pit Disassembly and Conversion Facility (PDCF) Project was to disassemble nuclear weapons pits and convert the resulting special nuclear materials to a form suitable for further disposition. Because of the nature of materials involved, the fundamental system which allowed PDCF to perform its mission was a series of integrated and interconnected gloveboxes which provided confinement and containment of the radioactive materials being processed. The high throughput planned for PDCF and the relatively high neutron and gamma radiation levels of the pits required that gloveboxes be shielded to meet worker dose limits. The glovebox shielding material was required to contain high hydrogen concentrations which typically result in these materials being combustible. High combustible loadings created design challenges for the facility fire suppression and ventilation system design. Combustible loading estimates for the PDCF Plutonium (Pu) Processing Building increased significantly due to these shielding requirements. As a result, the estimates of combustible loading substantially exceeded values used to support fire and facility safety analyses. To ensure a valid basis for combustible loading contributed by the glovebox system, the PDCF Project funded a series of fire tests conducted by the Southwest Research Institute on door panels and a representative glovebox containing Water Extended Polyester (WEP) radiological shielding to observe their behavior during a fire event. Improvements to PDCF glovebox designs were implemented based on lessons learned during the fire test. In particular, methods were developed to provide high levels of neutron shielding while maintaining combustible loading in the glovebox shells at low levels. Additionally, the fire test results led to design modifications to mitigate pressure increases observed during the fire test in order to maintain the integrity of the WEP cladding. These changes resulted in significantly reducing the credited combustible loading of the facility. These advances in glovebox design should be considered for application in nuclear facilities within the Department of Energy complex in the future.

Wildland Fire Management Plan for Brookhaven National Laboratory  

SciTech Connect

This Wildland Fire Management Plan (FMP) for Brookhaven National Lab (BNL) updates the 2003 plan incorporating changes necessary to comply with DOE Order 450.1 and DOE P 450.4, Federal Wildland Fire Management Policy and Program Review; Wildland and Prescribed Fire Management Policy and implementation Procedures Reference Guide. This current plan incorporates changes since the original draft of the FMP that result from new policies on the national level. This update also removes references and dependence on the U.S. Fish & Wildlife Service and Department of the Interior, fully transitioning Wildland Fire Management responsibilities to BNL. The Department of Energy policy for managing wildland fires requires that all areas, managed by the DOE and/or its various contractors, that can sustain fire must have a FMP that details fire management guidelines for operational procedures associated with wild fire, operational, and prescribed fires. Fire management plans provide guidance on fire preparedness, fire prevention, wildfire suppression, and the use of controlled, 'prescribed' fires and mechanical means to control the amount of available combustible material. Values reflected in the BNL Wildland FMP include protecting life and public safety; Lab properties, structures and improvements; cultural and historical sites; neighboring private and public properties; and endangered, threatened, and species of concern. Other values supported by the plan include the enhancement of fire-dependent ecosystems at BNL. This FMP will be reviewed periodically to ensure the fire program advances and evolves with the missions of the DOE and BNL. This Fire Management Plan is presented in a format that coverers all aspects specified by DOE guidance documents which are based on the national template for fire management plans adopted under the National Fire Plan. The DOE is one of the signatory agencies on the National Fire Plan. This FMP is to be used and implemented for the entire BNL site including the Upton Reserve and has been reviewed by, The Nature Conservancy, New York State Department of Environmental Conservation Forest Rangers, and DOE, as well as appropriate BNL emergency services personnel. The BNL Fire Department is the lead on wildfire suppression. However, the BNL Natural Resource Manager will be assigned to all wildland fires as technical resource advisor.

Coal-fired high performance power generating system. Quarterly progress report, October 1--December 31, 1992  

SciTech Connect

Our team has outlined a research plan based on an optimized analysis of a 250 MWe combined cycle system applicable to both frame type and aeroderivative gas turbines. Under the constraints of the cycle analysis we have designed a high temperature advanced furnace (FUTAF) which integrates several combustor and air heater designs with appropriate ash management procedures. The Cycle Optimization effort under Task 2 outlines the evolution of our designs. The basic combined cycle approach now includes exhaust gas recirculation to quench the flue gas before it enters the convective air heater. By selecting the quench gas from a downstream location it will be clean enough and cool enough (ca. 300F) to be driven by a commercially available fan and still minimize the volume of the convective air heater. Further modeling studies on the long axial flame, under Task 3, have demonstrated that this configuration is capable of providing the necessary energy flux to the radiant air panels. This flame with its controlled mixing constrains the combustion to take place in a fuel rich environment, thus minimizing the NO{sub x} production. Recent calculations indicate that the NO{sub x} produced is low enough that the SNCR section can further reduce it to within the DOE goal of 0. 15 lbs/MBTU of fuel input. Also under Task 3 the air heater design optimization continued.

Reduction of fire hazards on large mining equipment  

SciTech Connect

Although standards and regulations are in place to prevent large mining equipment fires, recent analyses of mine accident data show that mining equipment fires still occur with alarming frequency and grave consequences, particularly at all surface mines and in underground metal/nonmetal mines. Recently technological advances in fire protection, combined with the statistical data on equipment fires, led NIOSH to reinvestigate this and to improve operator safety. NIOSH demonstrated that newly developed technologies, such as dual cab fire inerting systems and engine compartment fire barriers, can greatly enhance operator safety and lessen the damage of property during large mobile equipment fires. 10 refs., 5 figs.

Engineering development of coal-fired high performance power systems, Phase 2 and 3. Quarterly progress report, October 1--December 31, 1995  

SciTech Connect

The goals of the program are to develop a coal-fired high performance power generation system (HIPPS) by the year 2000 that is capable of: >47% thermal efficiency (HHV); NO{sub x}, SO{sub x} and particulates {ge} 10% NSPS; coal {ge} 65% of heat input; all solid wastes benign; and cost of electricity 90% of present plant. The HIPPS generating plant integrates a combustion gas turbine/HRSG combined cycle arrangement with an advanced coal-fired boiler. The unique feature of the HIPPS plant is the partial heating of gas turbine (GT) compressor outlet air using energy released by firing coal in the high temperature advanced furnace (HITAF). The compressed air is additionally heated prior to entering the GT expander section by burning natural gas. Energy available, in the gas turbine exhaust and in the HITAF flue gas are used in a steam cycle to maximize energy production. The HIPPS plant arrangement is thus a combination of existing technologies (gas turbine, heat recovery boilers, conventional steam cycle) and new technologies (the HITAF design especially the heater located in the radiant section). Work reported herein is from Task 1.3, HIPPS Commercial Design and Task 2.2, HITAF Air Heaters.

Numeric modeling of fire suppression by organophosphorous inhibitors  

E-Print Network (OSTI)

Numerical calculations of the effect of organophosphorous inhibitor (CF3CH2O)3P and its mixtures with carbon dioxide on propane flames are carried out using the three dimensional Reynolds-averaged Navier-Stokes (RANS) equations in the low Mach number approximation. The k-e model of turbulence, the EDC combustion model and the weighted-sum-of-gray-gases model of radiation are used. The Westbrook global-kinetic scheme with fractional order of reaction was used for the calculation of chemical reaction rate of propane combustion. The empirical expression for the correction factor for the chemical reaction rate was used to model the effect of organophosphorous inhibitor no the reaction. Two series of test calculations for different values of the correction factor are carried out. Dependences of the minimum extinguishing concentration of the inhibitor per carbon dioxide volume concentration in the extinguishing mixtures were obtained. The results of test calculations are shown to agree reasonably with the experimen...

Development and testing of a commercial scale coal-fired combustion system, Phase 3. Quarterly technical progress report No. 8, July 1, 1992--September 30, 1992  

SciTech Connect

This report summarizes the results of work performed in the development and proof-of-concept (POC) testing of a coal-fired space heating system for the commercial market sector. The objective of this program is to design, build and test a coal based heating system for this sector and determine the economic viability and market potential for the system. Coal water slurry (CWS) fuel has been chosen as the fuel form for this development effort. CWS eliminates the need to use dry pulverized coal with its attendant handling, metering and dusting problems as well as its explosive potential. Equally important in selecting a fuel form is the impact on emission levels and pollution control equipment requirements. CWS is amenable to coal washing since coal cleaning technologies are generally water-based processes requiring the fine grinding of the coal. In the first stage. an overall system heat balance was prepared, system components were designed and manufactured or purchased, the system was fully assembled and preliminary testing performed to validate component performance and identify key operating variables. In the second stage the system was operated for prolonged periods to simulate a commercial application, and combustion and thermal efficiencies; tendencies to slag, foul, erode and corrode; and gaseous and particulate emissions were evaluated. Also during the second stage, an assessment of the commercial viability of the system was made. This assessment included an evaluation of the economics and market potential, including the sensitivity to fluctuations in fuel prices.

Development of a Low NOx Burner System for Coal Fired Power Plants Using Coal and Biomass Blends  

E-Print Network (OSTI)

The low NOx burner (LNB) is the most cost effective technology used in coal-fired power plants to reduce NOx. Conventional (unstaged) burners use primary air for transporting particles and swirling secondary air to create recirculation of hot gases. LNB uses staged air (dividing total air into primary, secondary and tertiary air) to control fuel bound nitrogen from mixing early and oxidizing to NOx; it can also limit thermal NOx by reducing peak flame temperatures. Previous research at Texas A&M University (TAMU) demonstrated that cofiring coal with feedlot biomass (FB) in conventional burners produced lower or similar levels of NOx but increased CO. The present research deals with i) construction of a small scale 29.31 kW (100,000 BTU/hr) LNB facility, ii) evaluation of firing Wyoming (WYO) coal as the base case coal and cofiring WYO and dairy biomass (DB) blends, and iii) evaluating the effects of staging on NOx and CO. Ultimate and Proximate analysis revealed that WYO and low ash, partially composted, dairy biomass (LA-PC-DB-SepS) had the following heat values and empirical formulas: CH0.6992N0.0122O0.1822S0.00217 and CH_1.2554N_0.0470O_0.3965S_0.00457. The WYO contained 3.10 kg of Ash/GJ, 15.66 kg of VM/GJ, 0.36 kg of N/GJ, and 6.21 kg of O/GJ while LA-PC-DB-SepS contained 11.57 kg of Ash/GJ, 36.50 kg of VM/GJ, 1.50 kg of N/GJ, and 14.48 kg of O/GJ. The construction of a LNB nozzle capable of providing primary, swirled secondary and swirled tertiary air for staging was completed. The reactor provides a maximum residence time of 1.8 seconds under hot flow conditions. WYO and DB were blended on a mass basis for the following blends: 95:5, 90:10, 85:15, and 80:20. Results from firing pure WYO showed that air staging caused a slight decrease of NOx in lean regions (equivalence ratio, greater than or equal to 1.0) but an increase of CO in rich regions (=1.2). For unstaged combustion, cofiring resulted in most fuel blends showing similar NOx emissions to WYO. Staged cofiring resulted in a 12% NOx increase in rich regions while producing similar to slightly lower amounts of NOx in lean regions. One conclusion is that there exists a strong inverse relationship between NOx and CO emissions.

A Sensor System Based on Semi-Conductor Metal Oxide Technology for In Situ Detection of Coal Fired Combustion Gases  

SciTech Connect

Sensor Research and Development Corporation (SRD) proposed a two-phase program to develop a robust, autonomous prototype analyzer for in situ, real-time detection, identification, and measurement of coal-fired combustion gases and perform field-testing at an approved power generation facility. SRD developed and selected sensor materials showing selective responses to carbon monoxide, carbon dioxide, nitric oxide, nitrogen dioxide, ammonia, sulfur dioxide and hydrogen chloride. Sensor support electronics were also developed to enable prototype to function in elevated temperatures without any issues. Field-testing at DOE approved facility showed the ability of the prototype to detect and estimate the concentration of combustion by-products accurately with relatively low false-alarm rates at very fast sampling intervals.

DEVELOPMENT OF FINE PARTICULATE EMISSION FACTORS AND SPECIATION PROFILES FOR OIL AND GAS-FIRED COMBUSTION SYSTEMS  

SciTech Connect

This report provides results from the first year of this three-year project to develop dilution measurement technology for characterizing PM2.5 (particles with aerodynamic diameter smaller than 2.5 micrometers) and precursor emissions from stationary combustion sources used in oil, gas and power generation operations. Detailed emission rate and chemical speciation test results for a refinery gas-fired process heater and plans for cogeneration gas turbine tests and pilot-scale tests are presented. Tests were performed using a research dilution sampling apparatus and traditional EPA methods to compare PM2.5 mass and chemical speciation. Test plans are presented for a gas turbine facility that will be tested in the fourth quarter of 2002. A preliminary approach for pilot-scale tests is presented that will help define design constraints for a new dilution sampler design that is smaller, lighter, and less costly to use.

Large-Scale Mercury Control Technology Testing for Lignite-Fired Utilities - Oxidation Systems for Wet FGD  

Science Conference Proceedings (OSTI)

Mercury (Hg) control technologies were evaluated at Minnkota Power Cooperative's Milton R. Young (MRY) Station Unit 2, a 450-MW lignite-fired cyclone unit near Center, North Dakota, and TXU Energy's Monticello Steam Electric Station (MoSES) Unit 3, a 793-MW lignite--Powder River Basin (PRB) subbituminous coal-fired unit near Mt. Pleasant, Texas. A cold-side electrostatic precipitator (ESP) and wet flue gas desulfurization (FGD) scrubber are used at MRY and MoSES for controlling particulate and sulfur dioxide (SO{sub 2}) emissions, respectively. Several approaches for significantly and cost-effectively oxidizing elemental mercury (Hg{sup 0}) in lignite combustion flue gases, followed by capture in an ESP and/or FGD scrubber were evaluated. The project team involved in performing the technical aspects of the project included Babcock & Wilcox, the Energy & Environmental Research Center (EERC), the Electric Power Research Institute, and URS Corporation. Calcium bromide (CaBr{sub 2}), calcium chloride (CaCl{sub 2}), magnesium chloride (MgCl{sub 2}), and a proprietary sorbent enhancement additive (SEA), hereafter referred to as SEA2, were added to the lignite feeds to enhance Hg capture in the ESP and/or wet FGD. In addition, powdered activated carbon (PAC) was injected upstream of the ESP at MRY Unit 2. The work involved establishing Hg concentrations and removal rates across existing ESP and FGD units, determining costs associated with a given Hg removal efficiency, quantifying the balance-of-plant impacts of the control technologies, and facilitating technology commercialization. The primary project goal was to achieve ESP-FGD Hg removal efficiencies of {ge}55% at MRY and MoSES for about a month.

A spray-suppression model for turbulent combustion  

SciTech Connect

A spray-suppression model that captures the effects of liquid suppressant on a turbulent combusting flow is developed and applied to a turbulent diffusion flame with water spray suppression. The spray submodel is based on a stochastic separated flow approach that accounts for the transport and evaporation of liquid droplets. Flame extinguishment is accounted for by using a perfectly stirred reactor (PSR) submodel of turbulent combustion. PSR pre-calculations of flame extinction times are determined using CHEMKIN and are compared to local turbulent time scales of the flow to determine if local flame extinguishment has occurred. The PSR flame extinguishment and spray submodels are incorporated into Sandia's flow fire simulation code, VULCAN, and cases are run for the water spray suppression studies of McCaffrey for turbulent hydrogen-air jet diffusion flames. Predictions of flame temperature decrease and suppression efficiency are compared to experimental data as a function of water mass loading using three assumed values of drop sizes. The results show that the suppression efficiency is highly dependent on the initial droplet size for a given mass loading. A predicted optimal suppression efficiency was observed for the smallest class of droplets while the larger drops show increasing suppression efficiency with increasing mass loading for the range of mass loadings considered. Qualitative agreement to the experiment of suppression efficiency is encouraging, however quantitative agreement is limited due to the uncertainties in the boundary conditions of the experimental data for the water spray.

The Carnol System for methanol production and CO{sub 2} mitigation from coal fired power plants and the transportation sector  

DOE Green Energy (OSTI)

The Carnol System consists of methanol production by CO{sub 2} recovered from coal fired power plants and natural gas and the use of the methanol as an alternative automotive fuel. The Carnol Process produces hydrogen by the thermal decomposition of natural gas and reacting the hydrogen with CO{sub 2} recovered from the power plant. The carbon produced can be stored or used as a materials commodity. A design and economic evaluation of the Carnol System is presented and compared to gasoline as an automotive fuel. An evaluation of the CO{sub 2} emission reduction of the process and system is made and compared to other conventional methanol production processes is including the use of biomass feedstock and methanol fuel cell vehicles. The CO{sub 2} for the entire Carnol System using methanol in automotive IC engines can be reduced by 56% compared to conventional system of coal plants and gasoline engines and by as much as 77% CO{sub 2} emission reduction when methanol is used in fuel cells in automotive engines. The Carnol System is shown to be an environmentally attractive and economically viable system connecting the power generation sector with the transportation sector which should warrant further development.

WILDLAND FIRE MANAGEMENT PLAN FOR BROOKHAVEN NATIONAL LABORATORY.  

SciTech Connect

This Wildland Fire Management Plan (FMP) for Brookhaven National Lab (BNL) and the Upton Ecological and Research Reserve (Upton Reserve) is based on the U.S. Fish & Wildlife Service (FWS) fire management planning procedures and was developed in cooperation with the Department of Energy (DOE) by Brookhaven Science Associates. As the Upton Reserve is contained within the BNL 5,265-acre site, it is logical that the plan applies to both the Upton Reserve and BNL. The Department of the Interior policy for managing wildland fires requires that all areas managed by FWS that can sustain fire must have an FMP that details fire management guidelines for operational procedures and specifies values to be protected or enhanced. Fire management plans provide guidance on fire preparedness, fire prevention, wildfire suppression, and the use of controlled, ''prescribed'' fires and mechanical means to control the amount of available combustible material. Values reflected in the BNL/Upton Reserve Wildland FMP include protecting life and public safety; Lab properties, structures and improvements; cultural and historical sites; neighboring private and public properties; and endangered and threatened species and species of concern. Other values supported by the plan include the enhancement of fire-dependent ecosystems at BNL and the Upton Reserve. This FMP will be reviewed periodically to ensure the fire program advances and evolves with the missions of FWS, BNL, and the Upton Reserve. This Fire Management Plan is a modified version of the Long Island National Wildlife Refuge Complex Fire plan (updated in 2000), which contains all FWS fire plan requirements and is presented in the format specified by the national template for fire management plans adopted under the National Fire Plan. The DOE is one of the signatory agencies on the National Fire Plan. FWS shall be, through an Interagency Agreement dated November 2000 (Appendix C), responsible for coordinating and implementing prescribed burns and fuel reduction projects in the Upton Reserve. Prescribed fire and fuel reduction in locations outside the Upton Reserve will be coordinated through the Natural Resource Management Program at BNL, and done in consultation with FWS. This FMP is to be used and implemented for the entire BNL site including the Upton Reserve and has been reviewed by FWS, The Nature Conservancy, New York State Department of Environmental Conservation Forest Rangers, and DOE, as well as appropriate BNL emergency services personnel.

Optimal control of quantum gates and suppression of decoherence in a system of interacting two-level particles  

E-Print Network (OSTI)

Methods of optimal control are applied to a model system of interacting two-level particles (e.g., spin-half atomic nuclei or electrons or two-level atoms) to produce high-fidelity quantum gates while simultaneously negating the detrimental effect of decoherence. One set of particles functions as the quantum information processor, whose evolution is controlled by a time-dependent external field. The other particles are not directly controlled and serve as an effective environment, coupling to which is the source of decoherence. The control objective is to generate target one- and two-qubit unitary gates in the presence of strong environmentally-induced decoherence and under physically motivated restrictions on the control field. The quantum-gate fidelity, expressed in terms of a novel state-independent distance measure, is maximized with respect to the control field using combined genetic and gradient algorithms. The resulting high-fidelity gates demonstrate the feasibility of precisely guiding the quantum evolution via optimal control, even when the system complexity is exacerbated by environmental coupling. It is found that the gate duration has an important effect on the control mechanism and resulting fidelity. An analysis of the sensitivity of the gate performance to random variations in the system parameters reveals a significant degree of robustness attained by the optimal control solutions.

Characterization and Suppression of the Electromagnetic Interference Induced Phase Shift in the JLab FEL Photo - Injector Advanced Drive Laser System  

SciTech Connect

The drive laser for the photo-cathode gun used in the JLab Free Electron Laser (FEL) facility had been experiencing various phase shifts on the order of tens of degrees (>20{sup o} at 1497 MHz or >40ps) when changing the Advanced Drive Laser (ADL) [2][3][4] micro-pulse frequencies. These phase shifts introduced multiple complications when trying to setup the accelerator for operation, ultimately inhibiting the robustness and overall performance of the FEL. Through rigorous phase measurements and systematic characterizations, we determined that the phase shifts could be attributed to electromagnetic interference (EMI) coupling into the ADL phase control loop, and subsequently resolved the issue of phase shift to within tenths of a degree (<0.5{sup o} at 1497 MHz or <1ps). The diagnostic method developed and the knowledge gained through the entire process will prove to be invaluable for future designs of similar systems.

Engineering development of advanced coal-fired low-emission boiler systems: Technical progress report No. 16, July-September 1996  

SciTech Connect

The overall objective of the Project is the expedited commercialization of advanced coal-fired low-emission boiler systems. The Project is under budget and generally on schedule. The current status is shown in the Milestone Schedule Status Report included as Appendix A. Under Task 7--Component development and optimization, the CeraMem filter testing was completed. Due to an unacceptably high flue gas draft loss, which will not be resolved in the POCTF timeframe, a decision was made to change the design of the flue gas cleaning system from Hot SNO{sub x}{sup {trademark}} to an advanced dry scrubber called New Integrated Desulfurization (NID). However, it is recognized that the CeraMem filter still has the potential to be viable in pulverized coal systems. In Task 8-- Preliminary POCTF design, integrating and optimizing the performance and design of the boiler, turbine/generator and heat exchangers of the Kalina cycle as well as the balance of plant design were completed. Licensing activities continued. A NID system was substituted for the SNO{sub x} Hot Process.

Dear Reader, The Quadrennial Fire Review (QFR) is a strategic assessment process that is conducted every four years to evaluate current mission strategies and capabilities against best estimates of the future environment for fire management. This integrated review is a joint effort of the five federal natural resource management agencies and their state, local, and tribal partners that constitute the wildland fire community. The objective is to create an integrated strategic vision document for fire management. The 2009 QFR presents incoming federal policy leadership and the agency senior executives with the driving forces for change, suggested mission strategies, and analyses of workforce and operational capabilities. The document provides a solid foundation for policy discussions within the federal agencies and, importantly, among the federal agencies and state, local, tribal, and other partners. While the QFR is not a formal policy or decision document, it sets the stage for a strategic conversation about future direction and change in fire management. Our thanks goes to the QFR Integration Panel members who led the two-year analysis and review process and who prepared the final report, along with those members of the wildland fire community who submitted information, commentary, and suggestions during the process. We look forward to joining our wildland fire colleagues in using the QFR to chart and implement a national approach to wildland fire management.

FIELD TEST PROGRAM FOR LONG-TERM OPERATION OF A COHPAC SYSTEM FOR REMOVING MERCURY FROM COAL-FIRED FLUE GAS  

SciTech Connect

With the Nation's coal-burning utilities facing the possibility of tighter controls on mercury pollutants, the U.S. Department of Energy is funding projects that could offer power plant operators better ways to reduce these emissions at much lower costs. Sorbent injection technology represents one of the simplest and most mature approaches to controlling mercury emissions from coal-fired boilers. It involves injecting a solid material such as powdered activated carbon into the flue gas. The gas-phase mercury in the flue gas contacts the sorbent and attaches to its surface. The sorbent with the mercury attached is then collected by the existing particle control device along with the other solid material, primarily fly ash. During 2001, ADA Environmental Solutions (ADA-ES) conducted a full-scale demonstration of sorbent-based mercury control technology at the Alabama Power E.C. Gaston Station (Wilsonville, AL). This unit burns a low-sulfur bituminous coal and uses a hot-side electrostatic precipitator (ESP) in combination with a Compact Hybrid Particulate Collector (COHPAC{trademark}) baghouse to collect fly ash. The majority of the fly ash is collected in the ESP with the residual being collected in the COHPAC{trademark} baghouse. Activated carbon was injected between the ESP and COHPAC{trademark} units to collect the mercury. Short-term mercury removal levels in excess of 90% were achieved using the COHPAC{trademark} unit. The test also showed that activated carbon was effective in removing both forms of mercury--elemental and oxidized. However, a great deal of additional testing is required to further characterize the capabilities and limitations of this technology relative to use with baghouse systems such as COHPAC{trademark}. It is important to determine performance over an extended period of time to fully assess all operational parameters. The project described in this report focuses on fully demonstrating sorbent injection technology at a coal-fired power generating plant that is equipped with a COHPAC{trademark} system. The overall objective is to evaluate the long-term effects of sorbent injection on mercury capture and COHPAC{trademark} performance. The work is being done on one-half of the gas stream at Alabama Power Company's Plant Gaston Unit 3 (nominally 135 MW). Data from the testing will be used to determine: (1) If sorbent injection into a high air-to-cloth ratio baghouse is a viable, long-term approach for mercury control; and (2) Design criteria and costs for new baghouse/sorbent injection systems that will use a similar, polishing baghouse (TOXECON{trademark}) approach.

Application of Multivariable Control to Oil and Coal Fired Boilers  

E-Print Network (OSTI)

Increased visibility provided by advanced measurement and control techniques has shown that control of oil and coal fired boilers is a complex problem involving simultaneous determination of flue gas carbon monoxide, hydrocarbon, opacity and temperature levels. A microcomputer-based control system which recognizes the inter-relationship of these variables has produced fuel savings averaging about 3% on coal and oil fired boilers. The system is described and case study data is presented for both coal and oil fired boilers.

Proof-of-concept tests of the magnetohydrodynamic steam-bottoming system at the DOE Coal-Fired Flow Facility. Final report  

DOE Green Energy (OSTI)

The development of coal-fired magnetohydrodynamic (MHD) power can be viewed as consisting of two parts; the topping cycle and the bottoming cycle. The topping cycle consists of the coal combustor, MHD generator and associated components. The bottoming cycle consists of the heat recovery, steam generation, seed recovery/regeneration, emissions control (gas and particulate), ash handling and deposition, and materials evaluation. The report concentrates on the bottoming cycle, for which much of the technology was developed at the University of Tennessee Space Institute (UTSI). Because of the complexity of the required technology, a number of issues required investigation. Of specific concern regarding the bottoming cycle, was the design of the steam cycle components and emissions control. First, the high combustion temperatures and the use of large quantities of potassium in the MHD combustor results in a difference in the composition of the gases entering the bottoming cycle compared to conventional systems. Secondly, a major goal of the UTSI effort was to use a variety of coals in the MHD system, especially the large reserves of high-sulfur coals available in the United States.

Engineering development of advanced coal-fired low-emission boiler systems. Technical progress report number 14, January--March, 1996  

SciTech Connect

The Project is under budget and generally on schedule. The current status is shown in the Milestone Schedule Status Report included as Appendix A. Task 7--Component Development and Optimization and Task 11--Subsystem Test Operation and evaluation are shown to be slightly behind schedule. Also, addition of Kalina technology may delay completion of Task 8. However, Phase 2 will be completed on schedule. The Project and plans for the POCTF were presented to the Richmond Power and Light Board of Directors. Technology transfer activities included delivering papers at two conferences, submitting paper abstracts for two other conferences and organizing a Technical Session for a conference. Under Task 7 the 200 acfm CeraMem filter test rig was installed at Richmond Power and Light and testing commenced. Low-NO{sub x} firing system work was essentially completed. In Task 8 integrating and optimizing the performance and design of the boiler, turbine/generator and heat exchangers of the Kalina cycle is proceeding but it has required much more time than anticipated. Preliminary designs of this equipment are nearly complete. Plant design and licensing activities will restart in April. The test designs and plan created in Task 9 were previously submitted and approved, although the plan for the 5,000 acfm CeraMem filter test will be updated following completion of the 200 acfm test. Task 10 work is nearly complete. The test rig for the 5,000 acfm CeraMem test has been shipped to the fabricator`s shop, inspected, cleaned and is being modified based on input from the 200 acfm testing. Task 11 work on the CeraMem filter was delayed and is expected to be started during the next reporting period. The second series of combustion testing of the low-NO{sub x} firing system was completed and the data is being analyzed. Early review indicates that 0.1 lb of NO{sub x}/million Btu may be achievable with reasonable stoichiometry and carbon loss.

Identifying Socio-ecological Factors Influencing the Use of Prescribed Fire to Maintain and Restore Ecosystem Health in Texas, USA and Northern Chihuahua, Mexico  

E-Print Network (OSTI)

There is a critical need for more studies to identify socio-ecological drivers that affect conservation and management of fire adapted ecosystems, yet studies that identify such variables and explore their interaction in specific systems are not only scarce but limited to only a few systems. Although information on the socio-ecological effects of prescribed fire application exists, there is no integrative framework that simultaneously considers the interplay between social and ecological factors affecting the use of prescribed fires. Fire suppression, together with other human and natural disturbances in grassland systems that are adapted to episodic fire, are the major factors that have contributed to the recruitment of woody species into grasslands worldwide. Even though the ecology of restoring these fire prone systems back to a grassland state is becoming clearer, the major hurdle to reintroducing historic fire at a landscape scale is its social acceptability. To address these deficiencies, I studied the socio-ecological factors influencing the use of prescribed fire in Texas, USA and Chihuahua, Mexico using a combination of quantitative and qualitative approaches to examine how social and ecological factors affect ecosystem conservation and management of semi-arid grassland systems. For the Texas case study I used quantitative survey data analyzed using logistic regression models and structural equation models. For the Mexico case study I used qualitative interviews gathered using a snowball network sampling approach and coded them based on the analytic themes of land cover change, institutional failure, market drivers, and population dynamics. Results from the Texas case study suggest that risk taking orientation and especially, perceived support from others when implementing prescribed burns, play important roles in determining attitudes towards the use of high-intensity prescribed fires, which are sometimes needed to restore ecosystems. Results from the Texas case study also highlight how membership in Prescribed Burn Associations (PBAs) influence land manager decisions regarding the use of prescribed fire by reducing concerns over lack of skills, knowledge and resources. Results emphasize the potential for PBAs to reduce risk concerns regarding the application of prescribed fire and are relevant to management of brush encroached areas. Through PBAs, effective landscape-scale solutions to the brush encroachment problem can be achieved in Texas. Results from the Mexico case study show how fire stopped effectively being a driving factor on this system decades ago. Socio-political and ecological changes at the national, and international level produced changes in land use disrupting historical fire patterns and contributing to the ecological deterioration of the area. Droughts combined with poor management practices have depleted the fuel needed to carry a fire. Landowners also face safety and legal concerns but in most cases, even if a landowner decided to implement a prescribed burn, an ecological threshold has been crossed and current fine fuel loads (grass) are insufficient to carry a fire that is sufficiently intense to reduce brush cover and restore grassland and savanna ecosystems. Based on my findings I can conclude that ecologically sound adaptive management and social capital are fundamental components of the livelihoods of landowners and land managers in both case studies. Work and investment that is focused on strengthening this social capital will have the most profound effects in maintaining the integrity of grassland systems at a landscape scale.

Detecting moving fires on coal conveyors  

SciTech Connect

To comply with certain elements of the Clean Air Act Amendments of 1990, a number of utilities operating coal fired power plants have switched to low-rank bituminous and semi-bituminous coals as an alternative to other fuels like natural gas. Power plants firing and handling this variety of coal may be extremely prone to fires nd explosions as the coal is conveyed from storage on to the boilers due to a phenomenon known as spontaneous combustion. The American Society of Testing for Materials ranks coals by their tendency to oxidize. The lower the coal`s rank, the greater its tendency to absorb oxygen and, consequently, the greater its tendency to spontaneously combust. This unique property creates a new type of fire and explosion hazard not previously experienced by many coal-fired plants. Fires involving coal crushers, storage silos, conveyors, bunkers and pulverizer mills generally occur as a result of two ignition sources: spontaneous combustion (self-heating) of coal and frictional heating of the coal`s conveyance system.

Cyber Friendly Fire  

Science Conference Proceedings (OSTI)

Cyber friendly fire (FF) is a new concept that has been brought to the attention of Department of Defense (DoD) stakeholders through two workshops that were planned and conducted by the Air Force Research Laboratory (AFRL) and research conducted for AFRL by the Pacific Northwest National Laboratory. With this previous work in mind, we offer a definition of cyber FF as intentional offensive or defensive cyber/electronic actions intended to protect cyber systems against enemy forces or to attack enemy cyber systems, which unintentionally harms the mission effectiveness of friendly or neutral forces. Just as with combat friendly fire, a fundamental need in avoiding cyber FF is to maintain situation awareness (SA). We suggest that cyber SA concerns knowledge of a system's topology (connectedness and relationships of the nodes in a system), and critical knowledge elements such as the characteristics and vulnerabilities of the components that comprise the system (and that populate the nodes), the nature of the activities or work performed, and the available defensive (and offensive) countermeasures that may be applied to thwart network attacks. A training implication is to raise awareness and understanding of these critical knowledge units; an approach to decision aids and/or visualizations is to focus on supporting these critical knowledge units. To study cyber FF, we developed an unclassified security test range comprising a combination of virtual and physical devices that present a closed network for testing, simulation, and evaluation. This network offers services found on a production network without the associated costs of a real production network. Containing enough detail to appear realistic, this virtual and physical environment can be customized to represent different configurations. For our purposes, the test range was configured to appear as an Internet-connected Managed Service Provider (MSP) offering specialized web applications to the general public. The network is essentially divided into a production component that hosts the web and network services, and a user component that hosts thirty employee workstations and other end devices. The organization's network is separated from the Internet by a Cisco ASA network security device that both firewalls and detects intrusions. Business sensitive information is stored in various servers. This includes data comprising thousands of internal documents, such as finance and technical designs, email messages for the organization's employees including the CEO, CFO, and CIO, the organization's source code, and Personally Identifiable client data. Release of any of this information to unauthorized parties would have a significant, detrimental impact on the organization's reputation, which would harm earnings. The valuable information stored in these servers pose obvious points of interest for an adversary. We constructed several scenarios around this environment to support studies in cyber SA and cyber FF that may be run in the test range. We describe mitigation strategies to combat cyber FF including both training concepts and suggestions for decision aids and visualization approaches. Finally, we discuss possible future research directions.

Repowering oil-fired boilers with combustion turbines fired with gas from coal. Final report  

Science Conference Proceedings (OSTI)

The results of a study on repowering of oil fired reheat steam plants using combustion turbines and coal gas from the Texaco oxygen blown gasifier are presented. The steam plant utilizes combustion turbine exhaust gas as its combustion air supply. In some examples coal gas is fired in both the combustion turbines and the main boiler, while, in other cases, oil firing is retained in the boiler. Plant configurations, equipment changes, and performance are determined for three basic forms: (1) repowering based on coal gas supplied by pipeline (remote source); (2) repowering based on complete integration of the gasification system with the power plant; and (3) repowering based on partial integration of the gasification system wherein the boiler retains oil firing.

FIELD TEST PROGRAM TO DEVELOP COMPREHENSIVE DESIGN, OPERATING AND COST DATA FOR MERCURY CONTROL SYSTEMS ON NON-SCRUBBED COAL-FIRED BOILERS  

Science Conference Proceedings (OSTI)

With the Nation's coal-burning utilities facing the possibility of tighter controls on mercury pollutants, the U.S. Department of Energy is funding projects that could offer power plant operators better ways to reduce these emissions at much lower costs. Mercury is known to have toxic effects on the nervous system of humans and wildlife. Although it exists only in trace amounts in coal, mercury is released when coal burns and can accumulate on land and in water. In water, bacteria transform the metal into methylmercury, the most hazardous form of the metal. Methylmercury can collect in fish and marine mammals in concentrations hundreds of thousands times higher than the levels in surrounding waters. One of the goals of DOE is to develop technologies by 2005 that will be capable of cutting mercury emissions 50 to 70 percent at well under one-half of today's costs. ADA Environmental Solutions (ADA-ES) is managing a project to test mercury control technologies at full scale at four different power plants from 2000--2003. The ADA-ES project is focused on those power plants that are not equipped with wet flue gas desulfurization systems. ADA-ES will develop a portable system that will be moved to four different utility power plants for field testing. Each of the plants is equipped with either electrostatic precipitators or fabric filters to remove solid particles from the plant's flue gas. ADA-ES's technology will inject a dry sorbent, such as fly ash or activated carbon, that removes the mercury and makes it more susceptible to capture by the particulate control devices. A fine water mist may be sprayed into the flue gas to cool its temperature to the range where the dry sorbent is most effective. PG&E National Energy Group is providing two test sites that fire bituminous coals and are both equipped with electrostatic precipitators and carbon/ash separation systems. Wisconsin Electric Power Company is providing a third test site that burns Powder River Basin (PRB) coal and has an electrostatic precipitator for particulate control. Alabama Power Company will host a fourth test at its Plant Gaston, which is equipped with a hot-side electrostatic precipitator and a downstream fabric filter.

Control and extinguishment of LPG fires. Final report  

SciTech Connect

Approximately 100 fire control and fire extinguishment tests were run on free-burning LPG pool fires from 25 ft/sup 2/ to 1600 ft/sup 2/ in area. The LPG was contained in concrete pits, and the pit floors were allowed to cool before the fires were ignited so that the burning rates were not influenced by boiloff from the warm floor. High expansion foam was used for fire control. The foam was applied from fixed generators located on the upwind side of the pit. Fires were controlled after foam application of less than a minute to about 10 minutes, depending on the application rate. Fires were extinguished with dry chemical agents applied through fixed piping systems with tankside nozzles and by manual application using hoselines and portable extinguishers. Fires could readily be extinguished in times ranging from a few seconds to about half a minute, depending on the application rate, system design, and ambient conditions. Additional tests were conducted in 1-ft/sup 2/ and 5-ft/sup 2/ pits to determine the boiloff rates for LPG spilled on concrete, a sand/soil mix, and polyurethane foam substrates. Burning rates for free-burning LPG pool fires from 1 ft/sup 2/ to 1600 ft/sup 2/ in area are also reported.

DEVELOPMENT OF FINE PARTICULATE EMISSION FACTORS AND SPECIATION PROFILES FOR OIL AND GAS-FIRED COMBUSTION SYSTEMS  

SciTech Connect

In 1997, the United States Environmental Protection Agency (EPA) promulgated new National Ambient Air Quality Standards (NAAQS) for particulate matter, including for the first time particles with aerodynamic diameter smaller than 2.5 micrometers ({micro}m) referred to as PM2.5. PM2.5 in the atmosphere also contributes to reduced atmospheric visibility, which is the subject of existing rules for siting emission sources near Class 1 areas and new Regional Haze rules. There are few existing data regarding emissions and characteristics of fine aerosols from oil, gas and power generation industry combustion sources, and the information that is available is generally outdated and incomplete. Traditional stationary source air emission sampling methods tend to underestimate or overestimate the contribution of the source to ambient aerosols because they do not properly account for primary aerosol formation, which occurs after the gases leave the stack. Primary aerosol includes both filterable particles that are solid or liquid aerosols at stack temperature plus those that form as the stack gases cool through mixing and dilution processes in the plume downwind of the source. These deficiencies in the current methods can have significant impacts on regulatory decision-making. PM2.5 measurement issues were extensively reviewed by the American Petroleum Institute (API) (England et al., 1998), and it was concluded that dilution sampling techniques are more appropriate for obtaining a representative particulate matter sample from combustion systems for determining PM2.5 emission rate and chemical speciation. Dilution sampling is intended to collect aerosols including those that condense and/or react to form solid or liquid aerosols as the exhaust plume mixes and cools to near-ambient temperature immediately after the stack discharge. These techniques have been widely used in recent research studies. For example, Hildemann et al. (1994) and McDonald et al. (1998) used filtered ambient air to dilute the stack gas sample followed by 80-90 seconds residence time to allow aerosol formation and growth to stabilize prior to sample collection and analysis. More accurate and complete emissions data generated using the methods developed in this program will enable more accurate source-receptor and source apportionment analysis for PM2.5 National Ambient Air Quality Standards (NAAQS) implementation and streamline the environmental assessment of oil, gas and power production facilities. The overall goals of this program were to: (1) Develop improved dilution sampling technology and test methods for PM2.5 mass emissions and speciation measurements, and compare results obtained with dilution and traditional stationary source sampling methods. (2) Develop emission factors and speciation profiles for emissions of fine particulate matter, especially organic aerosols, for use in source-receptor and source apportionment analyses. (3) Identify and characterize PM2.5 precursor compound emissions that can be used in source-receptor and source apportionment analyses.

Fire safety of LPG in marine transportation  

SciTech Connect

This report contains an analytical examination of cargo spill and fire hazard potential associated with the marine handling of liquefied petroleum gas (LPG) as cargo. Principal emphasis was on cargo transfer operations for ships unloading at receiving terminals, and barges loading or unloading at a terminal. Major safety systems, including emergency shutdown systems, hazard detection systems, and fire extinguishment and control systems were included in the analysis. Spill probabilities were obtained from fault tree analyses utilizing composite LPG tank ship and barge designs. Failure rates for hardware in the analyses were generally taken from historical data on similar generic classes of hardware, there being very little historical data on the specific items involved. Potential consequences of cargo spills of various sizes are discussed and compared to actual LPG vapor cloud incidents. The usefulness of hazard mitigation systems (particularly dry chemical fire extinguishers and water spray systems) in controlling the hazards posed by LPG spills and spill fires is also discussed. The analysis estimates the probability of fatality for a terminal operator is about 10/sup -6/ to 10/sup -5/ per cargo transfer operation. The probability of fatality for the general public is substantially less.

Smokeless Gasoline Fire Test  

SciTech Connect

As a result of the recent concern by environmentalists, the hypothetical accident thermal test can no longer be performed by simply burning gasoline in an open pit. The uncontrolled open pit technique creates thick, dense, black clouds of smoke which are not permitted by local authorities. This paper deals with the design of the fire test facility and the techniques used to eliminate the smoke plume. The techniques include the addition of excess air to the fire in combination with a spray of water mist near the fuel surface. The excess air technique has been used successfully in an experimental setup; it was found that the temperature could be controlled in the neighborhood of the required 1475 degrees F environment and the smoke could be reduced to very low levels. The water spray technique has been successfully used by others in similar applications and, on completion of a permanent fire test facility at Mound Laboratory (anticipated July, 1974), test results will be available. The water is believed to interact with the combustion reaction to provide more complete combustion. The permanent facility will be a 10 x 10 ft cement block enclosure lined with firebrick. It will be 8 ft high on three sides and 4 ft high on one side to provide for observation of the test. A 5000 gal underground tank provides storage for the aviation gasoline which is gravity fed to the fire.

Comparison of Single-Fired and Delay-Fired Explosions at Regional and Local Distances,  

SciTech Connect

A wide range of blasting practices are utilized by the U.S. mining industry resulting in dramatically different local and regional seismic signatures. This variability in blasting and resulting seismograms suggests that no single discriminant may be appropriate for identifying this class of sources. A range of blasting styles are identified in this paper and the distinguishing characteristics at regional distances are determined. The blasting styles are quantified with the help of mining company records and close-in acoustic,seismic and video graphic data. The regional data consists of portable deployments of high frequency and broadband sensors as well as data from the International Monitoring System Primary Array at Pinedale, Wyoming. Critical to the success of this study is the comparison of regional data from the mining explosions to data from contained, single-fired explosions. Two types of single-fired explosions are utilized, the first a calibration explosion (8 vertical boreholes with 5,000 lbs of explosives each) fired simultaneous. The second, single-fired explosion consists of a number of boreholes detonated simultaneously in the mine for the purpose of pre-splitting the material (driving fractures between boreholes) prior to a large cast shot. Data from these explosions provide the basis for identifying the source signatures of the more typical delay-fired explosions. At high frequencies the single-fired and delay-fired explosions exhibit very similar waveforms at regional distances.Both event types show a high P/L{sub g} ratio at the highest frequencies with L{sub g} dominating at lower frequencies. Mining explosions that cast material show an enrichment in surface wave energy at relatively long periods of 4-12 seconds. Timing anomalies are identified in a high percentage of mining explosions designed to cast material. The accidental, simultaneous detonation of a number of boreholes has been observed in 2 of 9 carefully instrumented cast blasts. These produce regional waveforms that can have characteristics of a single-fired explosion. Spectral scalloping is observed from some delay-fired explosions while not from others. The existence of these characteristics is dependent on the exact delay pattern utilized. Data from a single- fired explosion allows the assessment of local receiver effects that might appear as a characteristic of delay-firing. 9 figs.

ZERO SUPPRESSION FOR RECORDERS  

DOE Patents (OSTI)

A zero-suppression circuit for self-balancing recorder instruments is presented. The essential elements of the circuit include a converter-amplifier having two inputs, one for a reference voltage and the other for the signal voltage under analysis, and a servomotor with two control windings, one coupled to the a-c output of the converter-amplifier and the other receiving a reference input. Each input circuit to the converter-amplifier has a variable potentiometer and the sliders of the potentiometer are ganged together for movement by the servoinotor. The particular noveity of the circuit resides in the selection of resistance values for the potentiometer and a resistor in series with the potentiometer of the signal circuit to ensure the full value of signal voltage variation is impressed on a recorder mechanism driven by servomotor.

Micronized coal-fired retrofit system for SO{sub x} reduction Krakow clean fossil fuels and energy efficiency program. Final report  

SciTech Connect

This report describes results of a technical, financial and environmental assessment study for a project, which would have included a new TCS micronized coal-fired heating plant for the Produkcja I Hodowla Roslin Ogrodniczych (PHRO) Greenhouse Complex; Krzeszowice, Poland. Project site is about 20 miles west of Krakow, Poland. During the project study period, PHRO utilized 14 heavy oil-fired boilers to produce heat for its greenhouse facilities and also home heating to several adjacent apartment housing complexes. The boilers burn a high-sulfur content heavy crude oil, called mazute, The project study was conducted during a period extended from March 1996 through February 1997. For size orientation, the PHRO Greenhouse complex grows a variety of vegetables and flowers for the Southern Poland marketplace. The greenhouse area under glass is very large and equivalent to approximately 50 football fields, The new micronized coal fired boiler would have: (1) provided a significant portion of the heat for PHRO and a portion of the adjacent apartment housing complexes, (2) dramatically reduced sulfur dioxide air pollution emissions, while satisfying new Polish air regulations, and (3) provided attractive savings to PHRO, based on the quantity of displaced oil.

Co-firing a pressurized fluidized-bed combustion system with coal and refuse derived fuels and/or sludges. Task 16  

Science Conference Proceedings (OSTI)

The co-firing of waste materials with coal in utility scale power plants has emerged as an effective approach to produce energy and manage municipal waste. Leading this approach, the atmospheric fluidized-bed combustor (AFBC) has demonstrated its commercial acceptance in the utility market as a reliable source of power burning a variety of waste and alternative fuels. The fluidized bed, with its stability of combustion, reduces the amount of thermochemical transients and provides for easier process control. The application of pressurized fluidized-bed combustor (PFBC) technology, although relatively new, can provide significant enhancements to the efficient production of electricity while maintaining the waste management benefits of AFBC. A study was undertaken to investigate the technical and economic feasibility of co-firing a PFBC with coal and municipal and industrial wastes. Focus was placed on the production of electricity and the efficient disposal of wastes for application in central power station and distributed locations. Wastes considered for co-firing include municipal solid waste (MSW), tire-derived fuel (TDF), sewage sludge, and industrial de-inking sludge. Issues concerning waste material preparation and feed, PFBC operation, plant emissions, and regulations are addressed. This paper describes the results of this investigation, presents conclusions on the key issues, and provides recommendations for further evaluation.

Coal-fired diesel generator  

SciTech Connect

The objective of the proposed project is to test the technical, environmental, and economic viability of a coal-fired diesel generator for producing electric power in small power generating markets. Coal for the diesel generator would be provided from existing supplies transported for use in the University`s power plant. A cleanup system would be installed for limiting gaseous and particulate emissions. Electricity and steam produced by the diesel generator would be used to supply the needs of the University. The proposed diesel generator and supporting facilities would occupy approximately 2 acres of land adjacent to existing coal- and oil-fired power plant and research laboratory buildings at the University of Alaska, Fairbanks. The environmental analysis identified that the most notable changes to result from the proposed project would occur in the following areas: power plant configuration at the University of Alaska, Fairbanks; air emissions, water use and discharge, and the quantity of solid waste for disposal; noise levels at the power plant site; and transportation of coal to the power plant. No substantive adverse impacts or environmental concerns were identified in analyzing the effects of these changes.

GASIFICATION BASED BIOMASS CO-FIRING - PHASE I  

DOE Green Energy (OSTI)

Biomass gasification offers a practical way to use this locally available fuel source for co-firing traditional large utility boilers. The gasification process converts biomass into a low Btu producer gas that can be fed directly into the boiler. This strategy of co-firing is compatible with variety of conventional boilers including natural gas fired boilers as well as pulverized coal fired and cyclone boilers. Gasification has the potential to address all problems associated with the other types of co-firing with minimum modifications to the existing boiler systems. Gasification can also utilize biomass sources that have been previously unsuitable due to size or processing requirements, facilitating a reduction in the primary fossil fuel consumption in the boiler and thereby reducing the greenhouse gas emissions to the atmosphere.

GASIFICATION BASED BIOMASS CO-FIRING  

DOE Green Energy (OSTI)

Biomass gasification offers a practical way to use this widespread fuel source for co-firing traditional large utility boilers. The gasification process converts biomass into a low Btu producer gas that can be used as a supplemental fuel in an existing utility boiler. This strategy of co-firing is compatible with a variety of conventional boilers including natural gas and oil fired boilers, pulverized coal fired conventional and cyclone boilers. Gasification has the potential to address all problems associated with the other types of co-firing with minimum modifications to the existing boiler systems. Gasification can also utilize biomass sources that have been previously unsuitable due to size or processing requirements, facilitating a wider selection of biomass as fuel and providing opportunity in reduction of carbon dioxide emissions to the atmosphere through the commercialization of this technology. This study evaluated two plants: Wester Kentucky Energy Corporation's (WKE's) Reid Plant and TXU Energy's Monticello Plant for technical and economical feasibility. These plants were selected for their proximity to large supply of poultry litter in the area. The Reid plant is located in Henderson County in southwest Kentucky, with a large poultry processing facility nearby. Within a fifty-mile radius of the Reid plant, there are large-scale poultry farms that generate over 75,000 tons/year of poultry litter. The local poultry farmers are actively seeking environmentally more benign alternatives to the current use of the litter as landfill or as a farm spread as fertilizer. The Monticello plant is located in Titus County, TX near the town of Pittsburgh, TX, where again a large poultry processor and poultry farmers in the area generate over 110,000 tons/year of poultry litter. Disposal of this litter in the area is also a concern. This project offers a model opportunity to demonstrate the feasibility of biomass co-firing and at the same time eliminate poultry litter disposal problems for the area's poultry farmers.

Field Test Program for Long-Term Operation of a COHPAC System for Removing Mercury from Coal-Fired Flue Gas  

Science Conference Proceedings (OSTI)

This document provides a summary of the full-scale demonstration efforts involved in the project ''Field Test Program for Long-Term Operation of a COHPAC{reg_sign} System for Removing Mercury from Coal-Fired Flue Gas''. The project took place at Alabama Power's Plant Gaston Unit 3 and involved the injection of sorbent between an existing particulate collector (hot-side electrostatic precipitators) and a COHPAC{reg_sign} fabric filter (baghouse) downstream. Although the COHPAC{reg_sign} baghouse was designed originally for polishing the flue gas, when activated carbon injection was added, the test was actually evaluating the EPRI TOXECON{reg_sign} configuration. The results from the baseline tests with no carbon injection showed that the cleaning frequency in the COHPAC{reg_sign} unit was much higher than expected, and was above the target maximum cleaning frequency of 1.5 pulses/bag/hour (p/b/h), which was used during the Phase I test in 2001. There were times when the baghouse was cleaning continuously at 4.4 p/b/h. In the 2001 tests, there was virtually no mercury removal at baseline conditions. In this second round of tests, mercury removal varied between 0 and 90%, and was dependent on inlet mass loading. There was a much higher amount of ash exiting the electrostatic precipitators (ESP), creating an inlet loading greater than the design conditions for the COHPAC{reg_sign} baghouse. Tests were performed to try to determine the cause of the high ash loading. The LOI of the ash in the 2001 baseline tests was 11%, while the second baseline tests showed an LOI of 17.4%. The LOI is an indication of the carbon content in the ash, which can affect the native mercury uptake, and can also adversely affect the performance of ESPs, allowing more ash particles to escape the unit. To overcome this, an injection scheme was implemented that balanced the need to decrease carbon injection during times when inlet loading to the baghouse was high and increase carbon injection when inlet loading and mercury removal were low. The resulting mercury removal varied between 50 and 98%, with an overall average of 85.6%, showing that the process was successful at removing high percentages of vapor-phase mercury even with a widely varying mass loading. In an effort to improve baghouse performance, high-permeability bags were tested. The new bags made a significant difference in the cleaning frequency of the baghouse. Before changing the bags, the baghouse was often in a continuous clean of 4.4 p/b/h, but with the new bags the cleaning frequency was very low, at less than 1 p/b/h. Alternative sorbent tests were also performed using these high-permeability bags. The results of these tests showed that most standard, high-quality activated carbon performed similarly at this site; low-cost sorbent and ash-based sorbents were not very effective at removing mercury; and chemically enhanced sorbents did not appear to offer any benefits over standard activated carbons at this site.

Oxygen-Fired CO{sub 2} Recycle for Application to Direct CO{sub 2} Capture form Coal-Fired Power Plants  

SciTech Connect

The Southern Research/Southern Company 1 MWth Pilot-Scale Coal-Fired Test Facility was successfully retrofit to fire in either the traditional air-fired mode or with 100% oxygen and recycled flue gas, with a fully integrated feedback and control system, including oxygen and recycled flue gas modulation during startup, transfer, and shutdown, safety and operational interlocks, and data acquisition. A MAXON Staged Oxygen Burner for Oxy-Coal Applications produced a stable flame over a significant range of firing turn-down, staging, and while firing five different U.S. coal types. The MAXON burner design produces lower flame temperatures than for air firing, which will enable (A) Safe operation, (B) Reduction of recycle flow without concern about furnace flame temperatures, and (C) May likely be affective at reducing slagging and fouling in the boiler and super heater at full-scale Power Plants. A CFD model of the Oxy-fired Combustion Research Facility (OCRF) was used to predict the flame geometry and temperatures in the OCRF and make a comparison with the air-fired case. The model predictions were consistent with the experimental data in showing that the MAXON burner fired with oxygen produced lower flame temperatures than the air-fired burner while firing with air.

Dynamics of tritrophic interactions between solenopsis invicta, antonina graminis, and neodusmetia sangwani: do fire ants negatively impact the success of a biological control system?  

E-Print Network (OSTI)

Solenopsis invicta, the red imported fire ant, has recently become associated with Antonina graminis, an invasive pest, and Neodusmetia sangwani, biological control agent, and maybe negatively affecting established biological control. A preliminary survey outlined the range of A. graminis and its parasitoids, and found N. sangwani was present at a reduced rate in South Texas and in the southeastern United States. A greenhouse experiment demonstrated that S. invicta decreased the rate of parasitism of A. graminis by N. sangwani, with S. invicta directly interfering with oviposition. Interactions between S. invicta and A. gaminis may be facilitating the spread and establishment of two invasive pests which has a negative impact on established classical biological control of A. graminis by N. sangwani.

Suppressed Charmed B Decay  

SciTech Connect

This thesis describes the measurement of the branching fractions of the suppressed charmed B{sup 0} {yields} D{sup (*)-} a{sub 0}{sup +} decays and the non-resonant B{sup 0} {yields} D{sup (*)-} {eta}{pi}{sup +} decays in approximately 230 million {Upsilon}(4S) {yields} B{bar B} events. The data have been collected with the BABAR detector at the PEP-II B factory at the Stanford Linear Accelerator Center in California. Theoretical predictions of the branching fraction of the B{sup 0} {yields} D{sup (*)-} a{sub 0}{sup +} decays show large QCD model dependent uncertainties. Non-factorizing terms, in the naive factorization model, that can be calculated by QCD factorizing models have a large impact on the branching fraction of these decay modes. The predictions of the branching fractions are of the order of 10{sup -6}. The measurement of the branching fraction gives more insight into the theoretical models. In general a better understanding of QCD models will be necessary to conduct weak interaction physics at the next level. The presence of CP violation in electroweak interactions allows the differentiation between matter and antimatter in the laws of physics. In the Standard Model, CP violation is incorporated in the CKM matrix that describes the weak interaction between quarks. Relations amongst the CKM matrix elements are used to present the two relevant parameters as the apex of a triangle (Unitarity Triangle) in a complex plane. The over-constraining of the CKM triangle by experimental measurements is an important test of the Standard Model. At this moment no stringent direct measurements of the CKM angle {gamma}, one of the interior angles of the Unitarity Triangle, are available. The measurement of the angle {gamma} can be performed using the decays of neutral B mesons. The B{sup 0} {yields} D{sup (*)-} a{sub 0}{sup +} decay is sensitive to the angle {gamma} and, in comparison to the current decays that are being employed, could significantly enhance the measurement of this angle. However, the low expected branching fraction for the B{sup 0} {yields} D{sup (*)-} a{sub 0}{sup +} decay channels could severely impact the measurement. A prerequisite of the measurement of the CKM angle is the observation of the B{sup 0} {yields} D{sup (*)-} a{sub 0}{sup +} decay on which this thesis reports. The BABAR experiment consists of the BABAR detector and the PEP-II e{sup +}e{sup -} collider. The design of the experiment has been optimized for the study of CP violation in the decays of neutral B mesons but is also highly suitable for the search for rare B decays such as the B{sup 0} {yields} D{sup (*)-} a{sub 0}{sup +} decay. The PEP-II collider operates at the {Upsilon}(4S) resonance and is a clean source of B{bar B} meson pairs.

Alcohol fired alcohol fuel still  

Science Conference Proceedings (OSTI)

The best method for using alcohol as the base for alcohol fuel distillation would be in the conservation of the initial heat input. In other words, the 20 gallon system would, at the end of a load, in effect waste a full gallon of alcohol fuel with each batch. Therefore either a continual feed system needs to be developed which would serve the 20 gallon heater or heat exchangers of some type should be designed to salvage a great portion of the heat. If, on the other hand, large amounts of fuel are not required, a large single batch still fired by alcohol would not be too wasteful. It would be adviseable that some form of alcohol fuel research both small and large scale be continued. While not necessarily an important part of the energy picture now, it may well be in the future. It could also open up overseas markets where fuels in liquid form are scarce, yet raw materials are not. Lastly, this project, while accomplishing muon, needs further study to make the system more efficient in fuel economy.

From fire to ice  

Science Conference Proceedings (OSTI)

Absorption chillers are heat-operate refrigeration without harmful environmental emissions (CFCs, HCFCS, and HFCS). The machine uses either steam or a gas-fired burner as the energy source and utilizes endothermic evaporation to provide refrigeration to an external process fluid, usually chilled water. In the United States, absorption chillers are used in regions where the cost of electricity is high relative to natural gas. Absorption chillers are also used in applications where steam is readily available or in areas where seasonal load peaks cause utilities to subsidize gas cooling. This paper will describe the history of absorption, the basic absorption refrigeration cycle and some advanced high efficiency cycles. Practical applications of absorption refrigeration to commercial end uses will also be discussed.

Overview of the ARM/FIRE Water Vapor Overview of the ARM/FIRE Water Vapor Experiment (AFWEX) D. C. Tobin, H. E. Revercomb, and D. D. Turner University of Wisconsin-Madison Madison, Wisconsin Introduction An overview of the ARM/FIRE Water Vapor Experiment (AFWEX) is given. This field experiment was conducted during November-December 2000 near the central ground-based Atmospheric Radiation Measurement (ARM) site in north central Oklahoma, and was sponsored jointly by the ARM, the National Aeronautics and Space Administration (NASA) First ISCCP Regional Experiment (FIRE), and the National Polar-orbiting Operational Environmental Satellite System (NPOESS) programs. Its primary goal was to collect accurate measurements of upper-level (~8 to 12 km) water vapor near the ground-based ARM site. These data are being used to determine the accuracy of measurements that are

A study of toxic emissions from a coal-fired power plant utilizing an ESP/Wet FGD system. Volume 1, Sampling, results, and special topics: Final report  

Science Conference Proceedings (OSTI)

This was one of a group of assessments of toxic emissions from coal-fired power plants, conducted for DOE-PETC in 1993 as mandated by the 1990 Clean Air Act. It is organized into 2 volumes; Volume 1 describes the sampling effort, presents the concentration data on toxic chemicals in several power plant streams, and reports the results of evaluations and calculations. The study involved solid, liquid, and gaseous samples from input, output, and process streams at Coal Creek Station Unit No. 1, Underwood, North Dakota (1100 MW mine-mouth plant burning lignite from the Falkirk mine located adjacent to the plant). This plant had an electrostatic precipitator and a wet scrubber flue gas desulfurization unit. Measurements were conducted on June 21--24, 26, and 27, 1993; chemicals measured were 6 major and 16 trace elements (including Hg, Cr, Cd, Pb, Se, As, Be, Ni), acids and corresponding anions (HCl, HF, chloride, fluoride, phosphate, sulfate), ammonia and cyanide, elemental C, radionuclides, VOCs, semivolatiles (incl. PAH, polychlorinated dioxins, furans), and aldehydes. Volume 2: Appendices includes process data log sheets, field sampling data sheets, uncertainty calculations, and quality assurance results.

Development and testing of industrial scale, coal-fired combustion system, Phase 3. Seventeenth quarterly technical progress report, January 1, 1996--March 31, 1996  

SciTech Connect

In the first quarter of calendar year 1996, 9 days of combust-boiler tests were performed. Between these tests, modifications and improvements that were indicated by these tests were implemented. In January and early February, the modifications and installations indicated by the 6 days of testing in December 1995 were implemented. This was followed by 6 additional consecutive test days in mid- February. This was in turn followed by additional modifications, followed by a series of 3 one day, coal fired tests at end of March. These latter tests were the first ones in which slagging conditions were achieved in the combustor. The maximum thermal input was 13 MMBtu/hr, which equals two-thirds of the rated boiler heat input. The measured thermal, combustion, and slagging performance achieved in the combustor was superior to that achieved in the final series of tests conducted in Williamsport in 1993. The combustor-boiler facility is now ready for implementation of the task 5 site demonstration.

Atomic clocks with suppressed blackbody radiation shift  

E-Print Network (OSTI)

We develop a nonstandard concept of atomic clocks where the blackbody radiation shift (BBRS) and its temperature fluctuations can be dramatically suppressed (by one to three orders of magnitude) independent of the environmental temperature. The suppression is based on the fact that in a system with two accessible clock transitions (with frequencies v1 and v2) which are exposed to the same thermal environment, there exists a "synthetic" frequency v_{syn} (v1-e12 v2) largely immune to the BBRS. As an example, it is shown that in the case of ion 171Yb+ it is possible to create a clock in which the BBRS can be suppressed to the fractional level of 10^{-18} in a broad interval near room temperature (300\\pm 15 K). We also propose a realization of our method with the use of an optical frequency comb generator stabilized to both frequencies v1 and v2. Here the frequency v_{syn} is generated as one of the components of the comb spectrum and can be used as an atomic standard.

Analysis of large urban fires  

SciTech Connect

Fires in urban areas caused by a nuclear burst are analyzed as a first step towards determining their smoke-generation chacteristics, which may have grave implications for global-scale climatic consequences. A chain of events and their component processes which would follow a nuclear attack are described. A numerical code is currently being developed to calculate ultimately the smoke production rate for a given attack scenario. Available models for most of the processes are incorporated into the code. Sample calculations of urban fire-development history performed in the code for an idealized uniform city are presented. Preliminary results indicate the importance of the wind, thermal radiation transmission, fuel distributions, and ignition thresholds on the urban fire spread characteristics. Future plans are to improve the existing models and develop new ones to characterize smoke production from large urban fires. 21 references, 18 figures.

The CharXive Challenge. Regulation of global carbon cycles by vegetation fires  

E-Print Network (OSTI)

It is an open, but not unanswerable, question as to how much atmospheric CO2 is sequestered globally by vegetation fires. In this work I conceptualise the question in terms of the general CharXive Challenge, discuss a mechanism by which thermoconversion of biomass may regulate the global distribution of carbon between reservoirs, show how suppression of vegetation fires by human activities may increase the fraction of carbon in the atmospheric pool, and pose three specific CharXive Challenges of crucial strategic significance to our management of global carbon cycles.

Development of an advanced gas-fired mineral wool melter. Final report, October 1987-December 1990  

SciTech Connect

A gas-fired mineral wool melter was successfully designed and tested. The test results clearly show that the gas-fired melter offers significant advantages over the current state-of-the-art system, the coke-fired cupola. The primary benefits offered are: lower energy costs, fewer airborne pollutant emissions, virtual elimination of solid waste generation and superior control and quality of the resultant melt stream. Specifically, the unit eliminates the emission of carbon monoxide, hydrogen sulfide and hydrocarbons. Emissions of SOx and particulate are substantially reduced as well. The generation of solid wastes is eliminated through the gas-fired melters ability to utilize untreated process wastes as a feedstock.

Kink instability suppression with stochastic cooling pickup and kicker  

Science Conference Proceedings (OSTI)

The kink instability is one of the major beam dynamics issues of the linac-ring based electron ion collider. This head-tail type instability arises from the oscillation of the electron beam inside the opposing ion beam. It must be suppressed to achieve the desired luminosity. There are various ways to suppress the instability, such as tuning the chromaticity in the ion ring or by a dedicated feedback system of the electron beam position at IP, etc. However, each method has its own limitation. In this paper, we will discuss an alternative opportunity of suppressing the kink instability of the proposed eRHIC at BNL using the existing pickup-kicker syst
