Flash Steam Recovery Project  

E-Print Network (OSTI)

One of the goals of Vulcan's cost reduction effort is to reduce energy consumption in production facilities through energy optimization. As part of this program, the chloromethanes production unit, which produces a wide variety of chlorinated organic compounds, was targeted for improvement. This unit uses a portion of the high-pressure steam available from the plant's cogeneration facility. Continuous expansions within the unit had exceeded the optimum design capacity of the unit's steam/condensate recovery system, resulting in condensate flash steam losses to the atmosphere. Using computer simulation models and pinch analysis techniques, the Operational Excellence Group (Six Sigma) was able to identify a project to recover the flash steam losses as a supplemental low-pressure steam supply. The project was designed and implemented at no capital cost using existing instrumentation and controls. On an annualized basis steam usage per ton of product fell by about three percent. Absolute savings were about 15,800 million Btu.

NUCLEAR FLASH TYPE STEAM GENERATOR  

DOE Patents (OSTI)

A nuclear steam generating apparatus is designed so that steam may be generated from water heated directly by the nuclear heat source. The apparatus comprises a pair of pressure vessels mounted one within the other, the inner vessel containing a nuclear reactor heat source in the lower portion thereof to which water is pumped. A series of small ports are disposed in the upper portion of the inner vessel for jetting heated water under pressure outwardly into the atmosphere within the interior of the outer vessel, at which time part of the jetted water flashes into steam. The invention eliminates the necessity of any intermediate heat transfer medium and components ordinarily required for handling that medium. (AEC)

Steam atmosphere drying exhaust steam recompression system  

DOE Patents (OSTI)

This invention relates to a heated steam atmosphere drying system comprising dryer in combination with an exhaust recompression system which is extremely energy efficient and eliminates dangers known to air dryers. The system uses superheated steam as the drying medium, which recirculates through the system where its heat of evaporation and heat of compression is recovered, thereby providing a constant source of heat to the drying chamber. The dryer has inlets whereby feedstock and superheated steam are fed therein. High heat transfer and drying rates are achieved by intimate contact of the superheated steam with the particles being dried. The dryer comprises a vessel which enables the feedstock and steam to enter and recirculate together. When the feedstock becomes dry it will exit the dryer with the steam and become separated from the steam through the use of a curvilinear louver separator (CLS). The CLS enables removal of fine and ultrafine particles from the dryer. Water vapor separated from the particles in the CLS as superheated steam, may then be recovered and recirculated as steam through the use of a compressor to either directly or indirectly heat the dryer, and a heat exchanger or a heater to directly provide heat to the dryer. This system not only provides a very efficient heat transfer system but results in a minimum carry-over of ultrafine particles thereby eliminating any explosive hazard. 17 figures.

Flash drying protects standby plants  

Science Conference Proceedings (OSTI)

This article describes how special fast-drying technique provides effective corrosion protection for units that will be in standby for a short time. The Jacksonville Electric Authority (JEA) has developed a technique for rapidly drying out its boilers as an effective corrosion prevention measure, even for units which will be out of service for a short time. The JEA has several steam generating units that are not in continual service. These units, whether on standby or in extended cold storage, must be maintained if they are to operate reliably when they are needed. JEA uses dehumidification as the primary method to reduce corrosion in these standby units. Engineers at JEA believe it is better to reduce the amount of water retained in standby boilers than to add inhibiting chemicals to retained water for corrosion protection.

Steam atmosphere drying concepts using steam exhaust recompression  

SciTech Connect

In the US industrial drying accounts for approximately 1.5 quads of energy use per year. Annual industrial dryer expenditures are estimated to be in the $500 million range. Industrial drying is a significant energy and monetary expense. For the thermal drying processes in which water is removed via evaporation from the feedstock, attempts have been made to reduce the consumption of energy using exhaust waste heat recovery techniques, improved dryer designs, or even the deployment of advanced mechanical dewatering techniques. Despite these efforts, it is obvious that a large amount of thermal energy is often still lost if the latent heat of evaporation from the evaporated water cannot be recovered and/or in some way be utilized as direct heat input into the dryer. Tecogen Inc. is conducting research and development on an industrial drying concept. That utilizes a directly or indirectly superheated steam cycle atmosphere with exhaust steam recompression to recover the latent heat in the exhaust that would otherwise be lost. This approach has the potential to save 55 percent of the energy required by a conventional air dryer. Other advantages to the industrial dryer user include: A 35-percent reduction in the yearly cost per kg{sub evap} to dry wet feedstock, Reduced airborne emissions, Reduced dry dust fire/explosion risks, Hot product not exposed to oxygen thus, the product quality is enhanced, Constant rate drying in steam atmosphere, Reduced dryer size and cost, Reduced dryer heat losses due to lower dryer inlet temperatures. Tecogen has projected that the steam atmosphere drying system is most suitable as a replacement technology for state-of-the-art spray, flash, and fluidized bed drying systems. Such systems are utilized in the food and kindred products; rubber products; chemical and allied products; stone, clay, and glass; textiles; and pulp and paper industrial sectors.

Comparative analysis of alternative means for removing noncondensable gases from flashed-steam geothermal power plants  

DOE Green Energy (OSTI)

This is a final report on a screening study to compare six methods of removing noncondensable gases from direct-use geothermal steam power plants. This report defines the study methodologies and compares the performance and economics of selected gas-removal systems. Recommendations are presented for follow-up investigations and implementation of some of the technologies discussed. The specific gas-removal methods include five vacuum system configurations using the conventional approach of evacuating gas/vapor mixtures from the power plant condenser system and a system for physical separation of steam and gases upstream of the power turbine. The study focused on flashed-steam applications, but the results apply equally well to flashed-steam and dry-steam geothermal power plant configurations. Two gas-removal options appear to offer profitable economic potential. The hybrid vacuum system configurations and the reboiler process yield positive net present value results over wide-ranging gas concentrations. The hybrid options look favorable for both low-temperature and high-temperature resource applications. The reboiler looks profitable for low-temperature resource applications for gas levels above about 20,000 parts per million by volume. A vacuum system configuration using a three-stage turbocompressor battery may be profitable for low-temperature resources, but results show that the hybrid system is more profitable. The biphase eductor alternative cannot be recommended for commercialization at this time.

Performance Assessment of Flashed Steam Geothermal Power Plant  

DOE Green Energy (OSTI)

Five years of operating experience at the Comision Federal de Electricidad (CFE) Cerro Prieto flashed steam geothermal power plant are evaluated from the perspective of U. S. utility operations. We focus on the design and maintenance of the power plant that led to the achievement of high plant capacity factors for Units No. 1 and 2 since commercial operation began in 1973. For this study, plant capacity factor is the ratio of the average load on the machines or equipment for the period of time considered to the capacity rating of the machines or equipment. The plant capacity factor is the annual gross output in GWh compared to 657 GWh (2 x 37.5 MW x 8760 h). The CFE operates Cerro Prieto at base load consistent with the system connected electrical demand of the Baja California Division. The plant output was curtailed during the winter months of 1973-1975 when the system electric demand was less than the combined output capability of Cerro Prieto and the fossil fuel plant near Tijuana. Each year the system electric demand has increased and the Cerro Prieto units now operate at full load all the time. The CFE added Units 3 and 4 to Cerro Prieto in 1979 which increased the plant name plate capacity to 150 MW. Part of this additional capacity will supply power to San Diego Gas and Electric Company through an interconnection across the border. The achievement of a high capacity factor over an extensive operating period was influenced by operation, design, and maintenance of the geothermal flash steam power plant.

Design concepts for flash steam systems for use with medium temperature geothermal water  

SciTech Connect

Medium temperature water can be utilized for production of electrical energy when it is available in massive quantities. The design concepts herein are to provide a base for feasibility studies and evaluate processes with consideration of the economics of developing this electrical energy on a commercial scale. Two methods of producing electrical energy with geothermal water are being considered. The methods discussed in this document are by the flashing process of producing steam for driving turbine-generators. Flash steam systems were evaluated for use with 300/sup 0/F water. Single and multiflash systems were evaluated and component size sensitivity to operating pressures were studied. It was determined that a double flash system is the most practical system. Net power production of approximately 2.4 megawatts/million pounds per hour of brine is estimated for the double flash system which operates at an initial flash pressure of 30 psia and a second stage pressure of 13 psia. Flash pressures below atmospheric are not recommended due to oxygen leakage into the system. Sensitivity analysis has indicated that the power output is not highly sensitive to the first stage flash pressure. A significant loss in power output occurs if the second stage pressure is increased significantly.

Experimental and analytical studies of hydrocarbon yields under dry-, steam-, and steam with propane-distillation  

E-Print Network (OSTI)

Recent experimental and simulation studies -conducted at the Department of Petroleum Engineering at Texas A&M University - confirm oil production is accelerated when propane is used as an additive during steam injection. To better understand this phenomenon, distillation experiments were performed using seven-component synthetic oil consisting of equal weights of the following alkanes: n-C5, n-C6, n-C7, n-C8, n-C9, nC10, and n-C15. For comparison purposes, three distillation processes were investigated: dry-, steam-, and steam-propane-distillation, the latter at a propane:steam mass ratio of 0.05. The injection rate of nitrogen during dry-and steam-distillation was the same as that of propane during steam-propane distillation, 0.025 g/min, with steam injection rate kept at 0.5 g/min. The distillation temperatures ranged from 115C to 300C and were increased in steps of 10C. The cell was kept at each temperature plateau (cut) for 30 minutes. Distillation pressures ranged from 0 psig for dry distillation to 998 psig for steam-and steam-propane distillation. The temperature-pressure combination used represented 15C superheated steam conditions. Distillate samples were collected at each cut, and the volume and weight of water and hydrocarbon measured. In addition, the composition of the hydrocarbon distillate was measured using a gas chromatograph. Main results of the study may be summarized as follows. First, the hydrocarbon yield at 125C is highest with steam-propane distillation (74 wt%) compared to steam distillation (58 wt%), and lowest with dry distillation (36 wt%). This explains in part the oil production acceleration observed in steam-propane displacement experiments. Second, the final hydrocarbon yield at 300C however is the same for the three distillation processes. This observation is in line with the fact that oil recoveries were very similar in steam- and steam-propane displacement experiments. Third, based on the yields of individual hydrocarbon components, steam-propane distillation lowers the apparent boiling points of the hydrocarbons significantly. This phenomenon may be the most fundamental effect of propane on hydrocarbon distillation, which results in a higher yield during steam-propane distillation and oil production acceleration during steam-propane displacement. Fourth, experimental K-values are higher in distillations with steam-propane for the components n-hexane, n-heptane, n-octane, and n-nonane. Fifth, vapor fugacity coefficients for each component are higher in distillations with steam-propane than with steam. Finally, Gibbs excess energy is overall lower in distillations with steam-propane than with steam. The experimental results clearly indicate the importance of distillation on oil recovery during steam-or steam-propane injection. The experimental procedure and method of analysis developed in this study (for synthetic oil) will be beneficial to future researchers in understanding the effect of propane as steam additive on actual crude oils.

Experimental and analytical studies of hydrocarbon yields under dry-, steam-, and steam-with-propane distillation  

E-Print Network (OSTI)

Simulation study has shown oil production is accelerated when propane is used as an additive during steam injection. To better understand this phenomenon, distillation experiments were performed using San Ardo crude oil (12oAPI). For comparison purposes, three distillation processes were investigated: dry-, steam-, and steam-propanedistillation, the latter at the propane-to-steam mass ratio of 0.05 at steam injection rate 0.5 g/min. Two sets of the distillation experiments were carried out. In the first set of experiments, the distillation temperatures ranged from 115ºC to 300ºC. Distillation pressures ranged from 0 psig to 998 psig for steam- and steam-propane distillation. The temperature-pressure combination used represented 15ºC superheated steam conditions. In the second set of experiments, the distillation temperatures ranged from 220oC to 300oC at 260 psig. The temperature pressure combination used represented field conditions for crude oil. For both conditions, the cell was kept at each temperature plateau (cut) until no increase occurs in distillation yields. Distillation yields were collected at each cut, and the volume and weight of water and hydrocarbon measured. Based on these experiments, a thermodynamic modeling framework was developed that describes distillation effect and oil production for steam distillation experiments. The model is based on composition of crude oil, molecular weight of heavy fraction. The analytical model results are compared against the experimental data for synthetic crude and crude oil to verify the validity of the model. Main results of the study may be summarized as follows. The yields for steam distillation for saturated conditions of Tsat+15 o C and Psat is 10 % and with addition of 5% of propane to steam no significant increase occurs in distillation yields. The yields for steam distillation for field conditions of 260 psig and temperature range (220 ~300oC) is 18 % and with addition of 5% of propane to steam no significant increase in distillation yields. The results indicate that propane has minimal distillation effect on the heavy oil. This occurs possibly because of lesser amount of light fractions in the heavy oil that enhance the separation of components in the oil caused by the concentration gradient.

DOE Green Energy (OSTI)

The objective of the project was to analyze the capacity and availability factors of an operating direct flash geothermal power plant. The analysis was to include consideration of system and component specifications, operating procedures, maintenance history, malfunctions, and outage rate. The plant studied was the 75 MW(e) geothermal power plant at Cerro Prieto, Mexico, for the years 1973 to 1979. To describe and assess the plant, the project staff reviewed documents, visited the plant, and met with staff of the operating utility. The high reliability and availability of the plant was documented and actions responsible for the good performance were identified and reported. The results are useful as guidance to US utilities considering use of hot water geothermal resources for power generation through a direct flash conversion cycle.

Using dry fuel provides significant benefits to combustion boilers, mainly increased boiler efficiency, lower air emissions, and improved boiler operation. The three main choices for drying biomass are rotary dryers, flash dryers, and superheated steam dryers. Which dryer is chosen for a particular application depends very much on the material characteristics of the biomass, the opportunities for integrating the process and dryer, and the environmental controls needed or already available.

Steam Quality  

E-Print Network (OSTI)

"STEAM QUALITY has been generally defined as the amount of moisture/vapor (or lack thereof) contained within steam produced from some form of boiler. It has long been used as the standard term for the measurement of ""wet or dry"" steam and as a means of measuring enthalpy. Totally dry steam is said to be ""saturated"" steam. It is sometimes defined as the ""dryness faction"". The term in its historical denotation refers to a physical attribute of the steam. That attribute being ""what is the percentage water vapor content of the steam"" as compared to the amount of steam. Dry saturated steam is steam which carries no water vapor with it and is defined as having a quality of 1.00 (100%). Since water vapor is always present at the interface between the water level and the steam in a boiler, some water vapor will always tend to pass through the system with the steam. Hence, a continuing problem. If steam does carry water vapor past the separators it will tend to coalesce as a liquid, and in doing so it also will carry boiler chemicals with it."

Combined thermal storage pond and dry cooling tower waste heat rejection system for solar-thermal steam-electric power plants. Final report  

DOE Green Energy (OSTI)

The thermal performance and economics of the combined thermal storage pond and dry cooling tower waste heat rejection system concept for solar-thermal steam-electric plants have been evaluated. Based on the computer simulation of the operation of southwest-sited solar-thermal plants, it has been determined that the combined pond-tower concept has significant cost and performance advantages over conventional dry cooling systems. Use of a thermal storage pond as a component of the dry cooling system allows a significant reduction in the required dry cooling heat exchange capacity and the associated parasitic power consumption. Importantly, it has been concluded that the combined pond-tower dry cooling system concept can be employed to economically maintain steam condensing temperatures at levels normally achieved with conventional evaporative cooling systems. An evaluation of alternative thermal storage pond design concepts has revealed that a stratified vertical-flow cut-and-fill reservoir with conventional membrane lining and covering would yield the best overall system performance at the least cost.

Steam in Distribution and Use: Steam Quality Redefined  

E-Print Network (OSTI)

Steam quality is an important measurement in steam generation. It's a measurement of steam to moisture ratio. In use, steam quality takes on a different meaning- steam which maximizes energy transfer. To do this, the steam must be clean, dry, of desired pressure and free of air and non-condensible gases. Objectives in these areas should be set and an action plan implemented. Typical objectives could be to specify steam pressure delivery of maximum pressure and to use steam at the lowest pressure possible. Steam velocity ranges and maximum system pressure drops should be set. Cleaning steam and protecting control devices is an important means of maintaining quality. Draining condensate and venting air and other gases preserves the steam quality at the point of use. Poor pressure control yields poor operation and efficiency. Dirty steam causes valve leaks and maintenance problems. Improper drainage and venting can cause premature corrosion and poor heat transfer.

Typical objectives could be to specify steam pressure delivery of maximum pressure and to use steam at the lowest pressure possible. Steam velocity ranges and maximum system pressure drops should be set. Cleaning steam and protecting control devices is an important means of maintaining quality. Draining condensate and venting air and other gases preserves the steam quality at the point of use. Poor pressure control yields poor operation and efficiency. Dirty steam causes valve leaks and maintenance problems. Improper drainage and venting can cause premature corrosion and poor heat transfer."

Change steam tapping to save energy  

SciTech Connect

Induction turbines are common in large plants. They use both high pressure (HP) and low pressure (LP) steam and exhaust into a surface condenser operating under vacuum. Induction turbines are especially useful since they use maximum available LP steam with a balanced amount of HP steam and thus, achieve the best overall thermodynamic efficiency. LP steam is generally available as flash steam for boiler blow down, exhausts from back pressure turbines, process waste-heat recovery, etc. Typically, an LP steam header is routed around the plant with several connections to receive and supply steam. Therefore, it is common to connect each steam user/supplier to the nearest point on the main header. The portion of the header where steam turbine exhausts are connected has superheated LP steam and the header portion which receives steam from waste heat recovery, boiler blow down, etc., has saturated LP steam. Some portion of the header has mixed steam. Thus, the temperature of LP steam in the header varies over its length.

Steam Pressure Reduction, Opportunities, and Issues  

Science Conference Proceedings (OSTI)

Steam pressure reduction has the potential to reduce fuel consumption for a minimum capital investment. When the pressure at the boiler is reduced, fuel and steam are saved as a result of changes in the high-pressure side of the steam system from the boiler through the condensate return system. In the boiler plant, losses from combustion, boiler blowdown, radiation, and steam venting from condensate receivers would be reduced by reducing steam pressure. Similarly, in the steam distribution system, losses from radiation, flash steam vented from condensate receivers, and component and steam trap leakage would also be reduced. There are potential problems associated with steam pressure reduction, however. These may include increased boiler carryover, boiler water circulation problems in watertube boilers, increased steam velocity in piping, loss of power in steam turbines, and issues with pressure reducing valves. This paper is based a Steam Technical Brief sponsored by the U.S. Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy and Enbridge Gas Distribution, Inc. (5). An example illustrates the use of DOE BestPractices Steam System Assessment Tool to model changes in steam, fuel, electricity generation, and makeup water and to estimate resulting economic benefits.

Optimized Control Of Steam Heating Coils  

E-Print Network (OSTI)

Steam has been widely used as the source of heating in commercial buildings and industries throughout the twentieth century. Even though contemporary designers have moved to hot water as the primary choice for heating, a large number of facilities still use steam for heating. Medical campuses with on-site steam generation and extensive distribution systems often serve a number of buildings designed prior to the mid-1980s. The steam is typically used for preheat as its high thermal content helps in heating the air faster and prevents coils from freezing in locations with extreme weather conditions during winter. The present work provides a comprehensive description of the various types of steam heating systems, steam coils, and valves to facilitate the engineer's understanding of these steam systems. A large percentage of the steam coils used in buildings are provided with medium pressure steam. Veterans Integrated Service Network and Army Medical Command Medical Facilities are examples which use medium pressure steam for heating. The current design manual for these medical facilities recommends steam at 30psig be provided to these coils. In certain cases although the steam heating coil is designed for a 5psig steam pressure, it is observed that higher pressure steam is supplied at the coil. A higher steam pressure may lead to excessive heating, system inefficiency due to increased heat loss, simultaneous heating and cooling, and increased maintenance cost. Field experiments were conducted to evaluate the effect of lowering steam pressure on the system performance. A 16% reduction in temperature rise across the coil was found when the steam pressure in the coil was reduced from 15psig to 5psig. The rise in temperature with lower pressure steam was sufficient to prevent coil freeze-up even in the most severe weather conditions. Additional benefits of reduced steam pressure are reduced flash steam losses (flash steam is vapor or secondary steam formed when hot condensate from the coil is discharged into a lower pressure area, i.e., the condensate return line) and radiation losses, increased flow of air through the coil thereby reducing air stratification and reduced energy losses in the event of actuator failure. The work also involved evaluating the existing control strategies for the steam heating system. New control strategies were developed and tested to address the short comings of existing sequences. Improved temperature control and occupant comfort; elimination of valve hunting and reduced energy consumption were benefits realized by implementing these measures.

Flash protection controller  

DOE Patents (OSTI)

A controller provides a high voltage to maintain an electro-optic shutter in a transparent condition until a flash of light which would be harmful to personnel is sensed by a phototransistor. The controller then shorts the shutter to ground to minimize light transmission to the user and maintains light transmission at the pre-flash level for a predetermined time to allow the flash to subside. A log converter and differential trigger circuit keep the controller from being triggered by other light flashes which are not dangerous.

Steam Pricing  

E-Print Network (OSTI)

Steam is used in many plants to furnish both heat and mechanical energy. It is typically produced in several fired boilers which may operate at different pressures and with different efficiencies. It is then distributed throughout the plant to the various users in steam distribution systems, each one operating at a different pressure and temperature. This paper examines various ways to cost steam and discusses the importance of proper costing. Specifically it addresses three types of steam costs; Marginal Costs, Project Evaluation Costs and Financial Costs.

Significant Silica Solubility in Geothermal Steam  

DOE Green Energy (OSTI)

Although it is widely believed that silica solubility in low pressure (5 to 10 bar) geothermal steam is negligible, when one takes into account steam flows exceeding 10 million tonnes a year--at Wairakei, for instance--it is found that the amount transmitted in the vapor has the potential to give significant deposits on turbine nozzles and blades. A 150 MWe power station, when based on flows from a hot water reservoir at (a) 250 C or (b) 315 C, and with separator pressures of 6 bar, is found to carry about 100 and 200 kg/year respectively in the steam phase. In the case of a similar sized station exploiting a dry steam reservoir such as The Geysers, equivalent silica flows are obtained, dissolved in steam and carried as dust--the latter as solid particles precipitating from the vapor en route from source to turbine, and not preexisting in the formations as is commonly considered. Choking or coating of subterranean rock near such dry steam wells due to exsolving silica, may be the principal cause of declining steam discharge under production. Silica from completely dry or superheated steam can also seal the cap and sides of steam reservoirs when expanding below the criticus temperature (236 C) in a way previously thought possible only by hot water or wet steam.

Impact of injection on reservoir performance in the NCPA steam field at The Geysers  

SciTech Connect

A managed injection program implemented by the NCPA in The Southeast Geysers reservoir continues to positively impact reservoir performance. Injection effects are determined by the application of geochemical and geophysical techniques to track the movement of injectate. This information, when integrated with reservoir pressure, flowrate, and thermodynamic data, is used to quantify the overall performance and efficiency of the injection program. Data analysis indicates that injected water is boiling near the injection wells, without deeper migration, and is recovered as superheated steam from nearby production wells. Injection derived steam (IDS) currently accounts for 25 to 35 percent of total production in the NCPA steamfield. Most importantly, 80 to 100% of the injectate is flashing and being recovered as steam. The amount of IDS has increased since 1988 due to both a change in injection strategy and a drying out of the reservoir. However, significant areas of the reservoir still remain relatively unaffected by injection because of the limited amount of injectate presently available. That the reservoir has been positively impacted in the injection areas is evidenced by a decrease in the rate of pressure decline from 1989 through 1992. Correspondingly, there has been a reduction in the rate of steam flow decline in the areas' production wells. Conversely, little evidence of reservoir cooling or thermal breakthrough is shown even in areas where IDS accounts for 80 percent or more of production. Finally, since injection water is a relatively low-gas source of steam, noncondensible gas concentrations have been reduced in some steam wells located within the injection dominated areas.

Potential use of dry cooling in support of advanced energy generation systems  

SciTech Connect

Advanced energy technologies were investigated for filling the energy supply and demand gap, including fuel cells, thermionic converters, and fusion. Technologies that have the potential for supplying energy in the future are solar, geothermal, coal gasification and liquefaction, clean solid fuel from coal, and oil shale. Results are presented of an analysis of the advanced energy generation systems, the potential for using dry cooling, and the waste heat generation characteristics of the advanced technologies. The magnitude of the waste heat expected to be generated indicates the following percentages of total cooling requirements would be needed by advanced energy technologies: (a) 1% to 2% in 1985, (b) 17% to 40% in 2000, and (c) 24% to 76% in 2025. Dry cooling could be required for flashed steam and dry steam geothermal plants if balancing withdrawal and reinjection of the geothermal fluid becomes a requirement. Binary cycle geothermal plants and plants using the hot dry rocks geothermmal resource are even more likely to require dry cooling since these plants will need an outside source of water. Solar central tower plants have a high potential for the use of dry cooling since they are likely to be located in the Southwest where water availability problems are already apparent. The high water consumption associated with the projected synthetic fuel production levels indicates that dry cooling will be desirable, perhaps even mandatory, to achieve a high level of synthetic fuel production. In the year 2000, between 2.5 and 13 GW of electrical energy produced by advanced power generation systems may require dry cooling. In the year 2025, this requirement may increase to between 4.5 and 81 GW/sub e/.

Steam purity in PWRs  

Science Conference Proceedings (OSTI)

Reports that 2 EPRI studies of PWRs prove that impure steam triggers decay of turbine metals. Reveals that EPRI is attempting to improve steam monitoring and analysis, which are key steps on the way to deciding the most cost-effective degree of steam purity, and to upgrade demineralizing systems, which can then reliably maintain that degree of purity. Points out that 90% of all cracks in turbine disks have occurred at the dry-to-wet transition zone, dubbed the Wilson line. Explains that because even very clean water contains traces of chemical impurities with concentrations in the parts-per-billion range, Crystal River-3's secondary loop was designed with even more purification capability; a deaerator to remove oxygen and prevent oxidation of system metals, and full-flow resin beds to demineralize 100% of the secondary-loop water from the condenser. Concludes that focusing attention on steam and water chemistry can ward off cracking and sludge problems caused by corrosion.

Steam-channel-expanding steam form drive  

SciTech Connect

In a viscous oil reservoir in which the stratification of the rock permeability is insufficient to confine steam within the most permeable strata, oil can be produced by forming and expanding a steam channel through which steam is flowed and oil is produced. Steam is injected and fluid is produced at rates causing a steam channel to be extended between locations that are horizontally separated. A foam-forming mixture of steam, noncondensable gas and surfactant is then injected into the steam channel to provide foam and a relatively high pressure gradient within the channel, without plugging the channel. A flow of steam-containing fluid through the steam channel is continued in a manner such that the magnitudes of the pressure gradient, the rate of oil production, and the rate of steam channel expansion exceed those which could be provided by steam alone. 10 claims, 6 figures.

Drying of fiber webs  

DOE Patents (OSTI)

A process and an apparatus for high-intensity drying of fiber webs or sheets, such as newsprint, printing and writing papers, packaging paper, and paperboard or linerboard, as they are formed on a paper machine. The invention uses direct contact between the wet fiber web or sheet and various molten heat transfer fluids, such as liquified eutectic metal alloys, to impart heat at high rates over prolonged durations, in order to achieve ambient boiling of moisture contained within the web. The molten fluid contact process causes steam vapor to emanate from the web surface, without dilution by ambient air; and it is differentiated from the evaporative drying techniques of the prior industrial art, which depend on the uses of steam-heated cylinders to supply heat to the paper web surface, and ambient air to carry away moisture, which is evaporated from the web surface. Contact between the wet fiber web and the molten fluid can be accomplished either by submersing the web within a molten bath or by coating the surface of the web with the molten media. Because of the high interfacial surface tension between the molten media and the cellulose fiber comprising the paper web, the molten media does not appreciately stick to the paper after it is dried. Steam generated from the paper web is collected and condensed without dilution by ambient air to allow heat recovery at significantly higher temperature levels than attainable in evaporative dryers.

SteamMaster: Steam System Analysis Software  

E-Print Network (OSTI)

As director of Oregon's Industrial Assessment Center, I have encountered many industrial steam systems during plant visits. We analyze steam systems and make recommendations to improve system efficiency. In nearly 400 industrial assessments, we have recommended 210 steam system improvements, excluding heat recovery, that would save $1.5 million/year with a 0.4-year payback. 75% of those recommendations have been implemented for $1.1 million annual savings with 0.3-year payback. Recently I have developed a tool to facilitate the process. SteamMaster is based on an Excel spreadsheet with a Visual Basic interface to simplify system modeling and analysis. SteamMaster has many features and capabilities, including energy and cost savings calculations for five steam recommendations. This presentation will demonstrate SteamMaster software applied to one or more industrial steam systems. Software will be made available on a national web site at no cost.

Performance Testing of Window Installation and Flashing Details  

E-Print Network (OSTI)

Protection of interface at windows and other penetrations from rainwater intrusion is a primary need of building structures. This is especially true when the building is in a high weather exposure location or in a climate in which the ability for walls to dry may be limited. Two areas of specific concern are: 1) the bottom corners of windows where damage is most commonly seen, and 2) the area around curved, arched or round-top windows where it is difficult to install the standard flashing materials. This paper reviews performance testing of window flashing installation methods commonly used in the trade, as well as improved methods made possible by recent advancements in flashing products. A series of laboratory tests were designed to determine water resistance, air leakage resistance and durability of several installation methods with different flashing materials. Windows were installed in test wall sections using several methods. The installations were monitored and evaluated for ease of installation and then tested for air leakage and water resistance using ASTM E283 and ASTM E331. The durability of the installations was then evaluated by subjecting the walls to thermal cycling (0 to 160oF) and retesting for water resistance using ASTM E331. Recommendations for best practice installation based on the testing results and key material selection issues are presented.

Steam Path Audits on Industrial Steam Turbines  

E-Print Network (OSTI)

The electric utility industry has benefitted from steam path audits on steam turbines for several years. Benefits include the ability to identify areas of performance degradation during a turbine outage. Repair priorities can then be set in accordance with quantitative results from the steam path audit. As a result of optimized repair decisions, turbine efficiency increases, emissions decrease, and maintenance expenses decrease. These benefits can be achieved by using a computer program Encotech, Inc. developed for the utility industry to perform steam path audits. With the increased emphasis on industrial turbine efficiency, and as a result of the experience with the Destec Operating Company, Encotech is adapting the computer program to respond to the needs of the industrial steam turbine community. This paper describes the results of using the STPE computer program to conduct a steam path audit at Destec Energy's Lyondell Cogeneration power plant.

Downhole steam quality measurement  

DOE Patents (OSTI)

The present invention relates to an empirical electrical method for remote sensing of steam quality utilizing flow-through grids which allow measurement of the electrical properties of a flowing two-phase mixture. The measurement of steam quality in the oil field is important to the efficient application of steam assisted recovery of oil. Because of the increased energy content in higher quality steam it is important to maintain the highest possible steam quality at the injection sandface. The effectiveness of a steaming operation without a measure of steam quality downhole close to the point of injection would be difficult to determine. Therefore, a need exists for the remote sensing of steam quality.

Steam Champions in Manufacturing  

E-Print Network (OSTI)

Traditionally, industrial steam system management has focused on operations and maintenance. Competitive pressures, technology evolution, and increasingly complex regulations provide additional management challenges. The practice of operating a steam system demands the managerial expertise of a "Steam Champion," which will be described in this paper. Briefly, the steam champion is a facility professional who embodies the skills, leadership, and vision needed to maximize the effectiveness of a plant's steam system. Perhaps more importantly, the steam champion's definitive role is that of liaison between the manufacturer's boardroom and the plant floor. As such, the champion is able to translate the functional impacts of steam optimization into equivalent corporate rewards, such as increased profitability, reliability, workplace safety, and other benefits. The prerequisites for becoming a true steam champion will include engineering, business, and management skills.

Steam Turbine Cogeneration  

E-Print Network (OSTI)

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

Steam trap monitor  

DOE Patents (OSTI)

A steam trap monitor positioned downstream of a steam trap in a closed steam system includes a first sensor (a hot finger) for measuring the energy of condensate and a second sensor (a cold finger) for measuring the total energy of condensate and steam in the line. The hot finger includes one or more thermocouples for detecting condensate level and energy, while the cold finger contains a liquid with a lower boiling temperature than that of water. Vapor pressure from the liquid is used to do work such as displacing a piston or bellow in providing an indication of total energy (steam + condensate) of the system. Processing means coupled to and responsive to outputs from the hot and cold fingers subtracts the former from the latter to provide an indication of the presence of steam downstream from the trap indicating that the steam trap is malfunctioning. 2 figs.

Steam turbine control  

SciTech Connect

In a power plant which includes a steam turbine with main control valves for admitting steam into the steam turbine and a steam bypass with bypass control valves for diverting steam around the steam turbine directly into a condenser, it is necessary to coordinate the operation of the respective valves so that the steam turbine can be started, brought up to speed, synchronized with a generator and then loaded as smoothly and efficiently as possible. The present invention provides for such operation and, in addition, allows for the transfer of power plant operation from the so-called turbine following mode to the boiler following mode through the use of the sliding pressure concept. The invention described is particularly applicable to combined cycle power plants.

Study of falling-jet flash evaporators  

DOE Green Energy (OSTI)

Experimental results of flash evaporation from sheets of water, 3.2 mm and 6.3 mm thick and 27.9 cm wide, falling freely in the presence of their own vapor, are reported. With no flashing the jets fall in coherent sheets, but with flashing the jets were observed to spread and break up into droplets. Flashing was characterized by an effectiveness parameter, which was found to increase with increasing water temperature and jet length. Variations in water flow rate and heat flux did not influence the effectiveness appreciably.

Steam turbine plant  

SciTech Connect

A system for regulating the rate of closing of the turbine intake valve of a steam turbine plant is disclosed. A steam turbine is supplied from a steam generator through a turbine intake valve. A branch line conducts the steam to a bypass valve which is normally closed. In the event of conditions making it necessary to close the turbine intake valve rapidly, a regulator is provided to control the rate of closing of the turbine intake valve and the opening of the bypass valve so that the pressure conditions in the steam generator do not exceed the limits established by the manufacturer. Pressure measuring instruments are placed in the system to sense the pressure immediately upstream from the turbine intake valve and the bypass valve as well as the initial steam supply pressure. These pressure signals are transmitted to a computer which produces a control signal in accordance with predetermined conditions.

Downhole steam injector  

SciTech Connect

An improved downhole steam injector has an angled water orifice to swirl the water through the device for improved heat transfer before it is converted to steam. The injector also has a sloped diameter reduction in the steam chamber to throw water that collects along the side of the chamber during slant drilling into the flame for conversion to steam. In addition, the output of the flame chamber is beveled to reduce hot spots and increase efficiency, and the fuel-oxidant inputs are arranged to minimize coking.

Steam and Condensate Systems  

E-Print Network (OSTI)

In the late 60's and early 70's oil was plentiful and steam was relatively inexpensive. The switch to low sulphur fuel oil and the oil embargo suddenly changed the picture. The cost of steam rose from about $0.50 per 1,000# to $3.00 or more. Many see costs of $5.00 per 1,000# by 1980. These tremendous increases have caused steam systems, steam traps and condensate systems to become a major factor in overall plant efficiency and profit.

Boiler steam engine with steam recovery and recompression  

SciTech Connect

A boiler type of steam engine is described which uses a conventional boiler with an external combustion chamber which heats water in a pressure chamber to produce steam. A mixing chamber is used to mix the steam from the boiler with recovered recompressed steam. Steam from the mixing chamber actuates a piston in a cylinder, thereafter the steam going to a reservoir in a heat exchanger where recovered steam is held and heated by exhaust gases from the combustion chamber. Recovered steam is then recompressed while being held saturated by a spray of water. Recovered steam from a steam accumulator is then used again in the mixing chamber. Thus, the steam is prevented from condensing and is recovered to be used again. The heat of the recovered steam is saved by this process.

Steam generator designs  

SciTech Connect

A combined cycle is any one of combinations of gas turbines, steam generators or heat recovery equipment, and steam turbines assembled for the reduction in plant cost or improvement of cycle efficiency in the utility power generation process. The variety of combined cycles discussed for the possibilities for industrial applications include gas turbine plus unfired steam generator; gas turbine plus supplementary fired steam generator; gas turbine plus furnace-fired steam generator; and supercharged furnace-fired system generator plus gas turbine. These units are large enough to meet the demands for the utility applications and with the advent of economical coal gasification processes to provide clean fuel, the combined-cycle applications are solicited.

Steam exit flow design for aft cavities of an airfoil  

DOE Patents (OSTI)

Turbine stator vane segments have inner and outer walls with vanes extending therebetween. The inner and outer walls have impingement plates. Steam flowing into the outer wall passes through the impingement plate for impingement cooling of the outer wall surface. The spent impingement steam flows into cavities of the vane having inserts for impingement cooling the walls of the vane. The steam passes into the inner wall and through the impingement plate for impingement cooling of the inner wall surface and for return through return cavities having inserts for impingement cooling of the vane surfaces. A skirt or flange structure is provided for shielding the steam cooling impingement holes adjacent the inner wall aerofoil fillet region of the nozzle from the steam flow exiting the aft nozzle cavities. Moreover, the gap between the flash rib boss and the cavity insert is controlled to minimize the flow of post impingement cooling media therebetween. This substantially confines outflow to that exiting via the return channels, thus furthermore minimizing flow in the vicinity of the aerofoil fillet region that may adversely affect impingement cooling thereof.

Steam trap monitor  

DOE Patents (OSTI)

A steam trap monitor positioned downstream of a steam trap in a closed steam system includes a first sensor (the combination of a hot finger and thermocouple well) for measuring the energy of condensate and a second sensor (a cold finger) for measuring the total energy of condensate and steam in the line. The hot finger includes one or more thermocouples for detecting condensate level and energy, while the cold finger contains a liquid with a lower boiling temperature than that of water. Vapor pressure from the liquid is used to do work such as displacing a piston or bellows in providing an indication of total energy (steam+condensate) of the system. Processing means coupled to and responsive to outputs from the thermocouple well hot and cold fingers subtracts the condensate energy as measured by the hot finger and thermocouple well from the total energy as measured by the cold finger to provide an indication of the presence of steam downstream from the trap indicating that the steam trap is malfunctioning.

Steam generator replacement overview  

Science Conference Proceedings (OSTI)

Since nuclear power began to be widely used for commercial purposes in the 1960s, unit operators have experienced a variety of problems with major components. Although many of the problems have diminished considerably, those associated with pressurized water reactor (PWR) steam generators persist. Steam generator problems rank second, behind refueling outages, as the most significant contributor to lost electricity generation. As of December 31, 1995, 38 steam generators had been replaced in 13 of the 72 operating PWRs, and three units had been shut down prematurely, due primarily (or partially) to degradation of their steam generators: Portland General Electric`s Trojan unit, located in Prescott, OR, in 1992; Southern California Edison`s San Onofre 1, located in San Clemente, CA, in 1992; and Sacramento Municipal Utility District`s Rancho Seco unit in 1989. In the coming years, operators of PWRs in the US with degraded steam generators will have to decide whether to make annual repairs (with eventual derating likely), replace the generators or shut the plants down prematurely. To understand the issues and decisions utility managers face, this article examines problems encountered at steam generators over the past few decades and identifies some of the remedies that utility operators and the nuclear community have employed, including operational changes, maintenance, repairs and steam generator replacement.

Waste Steam Recovery  

E-Print Network (OSTI)

An examination has been made of the recovery of waste steam by three techniques: direct heat exchange to process, mechanical compression, and thermocompression. Near atmospheric steam sources were considered, but the techniques developed are equally applicable to other sources of steam. The interaction of the recovery system with the plant's steam/power system has been included. Typical operating economics have been prepared. It was found that the profitability of most recovery schemes is generally dependent on the techniques used, the existing steam/power system, and the relative costs of steam and power. However, there will always be site-specific factors to consider. It is shown that direct heat exchange and thermocompression will always yield an energy profit when interacting with PRVs in the powerhouse. A set of typical comparisons between the three recovery techniques, interacting with various powerhouse and plant steam system configurations, is presented. A brief outline of the analysis techniques needed to prepare the comparison is also shown. Only operating costs are examined; capital costs are so size - and site-specific as to be impossible to generalize. The operating cost savings may be used to give an indication of investment potential.

Ukraine Steam Partnership  

SciTech Connect

The Ukraine Steam Partnership program is designed to implement energy efficiency improvements in industrial steam systems. These improvements are to be made by the private plants and local government departments responsible for generation and delivery of energy to end-users. One of the activities planned under this program was to provide a two-day training workshop on industrial steam systems focusing on energy efficiency issues related to the generation, distribution, and consumption of steam. The workshop was geared towards plant managers, who are not only technically oriented, but are also key decision makers in their respective companies. The Agency for Rational Energy Use and Ecology (ARENA-ECO), a non-governmental, not-for-profit organization founded to promote energy efficiency and environmental protection in Ukraine, in conjunction with the Alliance staff in Kiev sent out invitations to potential participants in all the regions of Ukraine. The purpose of this report is the describe the proceedings from the workshop and provide recommendations from the workshop's roundtable discussion. The workshop was broken down into two main areas: (1) Energy efficient boiler house steam generation; and Energy efficient steam distribution and consumption. The workshop also covered the following topics: (1) Ukrainian boilers; (2) Water treatment systems; (3) A profile of UKRESCO (Ukrainian Energy Services Company); (4) Turbine expanders and electricity generation; (5) Enterprise energy audit basics; and (6) Experience of steam use in Donetsk oblast.

Steam generator tube failures  

SciTech Connect

A review and summary of the available information on steam generator tubing failures and the impact of these failures on plant safety is presented. The following topics are covered: pressurized water reactor (PWR), Canadian deuterium uranium (CANDU) reactor, and Russian water moderated, water cooled energy reactor (VVER) steam generator degradation, PWR steam generator tube ruptures, the thermal-hydraulic response of a PWR plant with a faulted steam generator, the risk significance of steam generator tube rupture accidents, tubing inspection requirements and fitness-for-service criteria in various countries, and defect detection reliability and sizing accuracy. A significant number of steam generator tubes are defective and are removed from service or repaired each year. This wide spread damage has been caused by many diverse degradation mechanisms, some of which are difficult to detect and predict. In addition, spontaneous tube ruptures have occurred at the rate of about one every 2 years over the last 20 years, and incipient tube ruptures (tube failures usually identified with leak detection monitors just before rupture) have been occurring at the rate of about one per year. These ruptures have caused complex plant transients which have not always been easy for the reactor operators to control. Our analysis shows that if more than 15 tubes rupture during a main steam line break, the system response could lead to core melting. Although spontaneous and induced steam generator tube ruptures are small contributors to the total core damage frequency calculated in probabilistic risk assessments, they are risk significant because the radionuclides are likely to bypass the reactor containment building. The frequency of steam generator tube ruptures can be significantly reduced through appropriate and timely inspections and repairs or removal from service.

Steam purity in PWRs  

Science Conference Proceedings (OSTI)

Impurities enter the secondary loop of the PWR through both makeup water from lake or well and cooling-water leaks in the condenser. These impurities can be carried to the steam generator, where they cause corrosion deposits to form. Corrosion products in steam are swept further through the system and become concentrated at the point in the low-pressure turbine where steam begins to condense. Several plants have effectively reduced impurities, and therefore corrosion, by installing a demineralizer for the makeup water, a resin-bed system to clean condensed steam from the condenser, and a deaerator to remove oxygen from the water and so lower the risk of system metal oxidation. 5 references, 1 figure.

Evaluating Steam Trap Performance  

E-Print Network (OSTI)

Laboratory tests were conducted on several types of steam traps at Holston Defense Corporation in Kingsport, Tennessee. Data from these tests, which determined their relative efficiencies, were used in performing economic analyses to determine their equivalent uniform annual cost (EUAC). The comparison was made using a computer program written for the Apple II computer to evaluate overall steam trap economics. This program calculates the EUAC for any steam trap based on 12 input variables including capital, maintenance and steam costs, interest rate and trap life. After determinIng the EUAC, the program will perform sensitivity analyses on any of the twelve variables. (This computer program is available from the author.) This study shows that inverted bucket traps have lower EUAC's under more conditions than other types of traps. Also, this study shows that live steam loss is the heaviest contributor to the annual operating cost of any steam trap and that maintenance frequency and repair cost are also more important than a trap's first cost.

Single Particle Difraction at FLASH  

SciTech Connect

Single-pulse coherent diffraction patterns have been collected from randomly injected single particles with a soft X-ray free-electron laser (FEL). The intense focused FEL pulse gives a high-resolution low-noise coherent diffraction pattern of the object before that object turns into a plasma and explodes. A diffraction pattern of a single particle will only be recorded when the particle arrival into the FEL interaction region coincides with FEL pulse arrival and detector integration. The properties of the experimental apparatus coinciding with these three events set the data acquisition rate. For our single particle FLASH diffraction imaging experiments: (1) an aerodynamic lens stack prepared a particle beam that consisted of particles moving at 150-200 m/s positioned randomly in space and time, (2) the 10 fs long FEL pulses were delivered at a fixed rate, and (3) the detector was set to integrate and readout once every two seconds. The effect of these experimental parameters on the rate of data acquisition using randomly injected particles will be discussed. Overall, the ultrashort FEL pulses do not set the limit of the data acquisition, more important is the effective interaction time of the particle crossing the FEL focus, the pulse sequence structure and the detector readout rate. Example diffraction patterns of randomly injected ellipsoidal iron oxide nanoparticles in different orientations are presented. This is the first single particle diffraction data set of identical particles in different orientations collected on a shot-to-shot basis. This data set will be used to test algorithms for recovering 3D structure from single particle diffraction.

ACOUSTIC SIGNATURES OF THE HELIUM CORE FLASH  

SciTech Connect

All evolved stars with masses M {approx}< 2 M{sub Sun} undergo an initiating off-center helium core flash in their M{sub c} Almost-Equal-To 0.48 M{sub Sun} He core as they ascend the red giant branch (RGB). This off-center flash is the first of a few successive helium shell subflashes that remove the core electron degeneracy over 2 Myr, converting the object into a He-burning star. Though characterized by Thomas over 40 years ago, this core flash phase has yet to be observationally probed. Using the Modules for Experiments in Stellar Astrophysics (MESA) code, we show that red giant asteroseismology enabled by space-based photometry (i.e., Kepler and CoRoT) can probe these stars during the flash. The rapid ({approx}< 10{sup 5} yr) contraction of the red giant envelope after the initiating flash dramatically improves the coupling of the p-modes to the core g-modes, making the detection of l = 1 mixed modes possible for these 2 Myr. This duration implies that 1 in 35 stars near the red clump in the H-R diagram will be in their core flash phase. During this time, the star has a g-mode period spacing of {Delta}P{sub g} Almost-Equal-To 70-100 s, lower than the {Delta}P{sub g} Almost-Equal-To 250 s of He-burning stars in the red clump, but higher than the RGB stars at the same luminosity. This places them in an underpopulated part of the large frequency spacing ({Delta}{nu}) versus {Delta}P{sub g} diagram that should ease their identification among the thousands of observed red giants.

Solar production of industrial process steam. Quarterly performance report, January 16, 1980-June 30, 1980  

DOE Green Energy (OSTI)

A solar process steam system for gauze bleaching/sterilization utilizing 1065 m/sup 2/ Acurex Model 3001 line focusing parabolic trough concentrators is described. The system operates by circulating pressurized water through the collector field and then throttling it into a flash boiler. There the heated, pressurized water flashes to steam and flows into the plant steam main for distribution to various plant processes. Makeup water is supplied by the existing plant boiler feedwater system. The flash boiler retains enough thermal storage to provide freeze protection to the collector field when required. The system performance from January 16 to June 30 is summarized. A comparison of predicted and measured performance for a single day in June is presented. A summary of the operation of the system is given in Appendix A for each day of operation. Appendix B contains the hourly average values of system parameters for a single clear day in each month. These values are presented in graphical form in Appendix C. The daily values are tabulated in Appendix D and plotted in Appendix E for each month of operation. (MCW)

Steam assisted gas turbine engine  

SciTech Connect

A gas turbine engine is disclosed which has an integral steam power system consisting of heat absorbing boilers which convert an unpressurized liquid into an expanded and heated steam by utilizing heat normally lost through component cooling systems and the exhaust system. Upon completion of the steam power cycle, the steam is condensed back to a liquid state through a condensing system located within the compressor and other functional components of the gas turbine engine. A system of high pressure air and friction seals restrict steam or liquid condensate within designed flow bounds. The gas turbine engine disclosed is designed to give improved fuel efficiency and economy for aircraft and land use applications.

ADVANCED STEAM GENERATORS  

SciTech Connect

Concerns about climate change have encouraged significant interest in concepts for ultra-low or ''zero''-emissions power generation systems. In some proposed concepts, nitrogen is removed from the combustion air and replaced with another diluent such as carbon dioxide or steam. In this way, formation of nitrogen oxides is prevented, and the exhaust stream can be separated into concentrated CO{sub 2} and steam or water streams. The concentrated CO{sub 2} stream could then serve as input to a CO{sub 2} sequestration process or utilized in some other way. Some of these concepts are illustrated in Figure 1. This project is an investigation of one approach to ''zero'' emission power generation. Oxy-fuel combustion is used with steam as diluent in a power cycle proposed by Clean Energy Systems, Inc. (CES) [1,2]. In oxy-fuel combustion, air separation is used to produce nearly pure oxygen for combustion. In this particular concept, the combustion temperatures are moderated by steam as a diluent. An advantage of this technique is that water in the product stream can be condensed with relative ease, leaving a pure CO{sub 2} stream suitable for sequestration. Because most of the atmospheric nitrogen has been separated from the oxidant, the potential to form any NOx pollutant is very small. Trace quantities of any minor pollutants species that do form are captured with the CO{sub 2} or can be readily removed from the condensate. The result is a nearly zero-emission power plant. A sketch of the turbine system proposed by CES is shown in Figure 2. NETL is working with CES to develop a reheat combustor for this application. The reheat combustion application is unusual even among oxy-fuel combustion applications. Most often, oxy-fuel combustion is carried out with the intent of producing very high temperatures for heat transfer to a product. In the reheat case, incoming steam is mixed with the oxygen and natural gas fuel to control the temperature of the output stream to about 1480 K. A potential concern is the possibility of quenching non-equilibrium levels of CO or unburned fuel in the mixing process. Inadequate residence times in the combustor and/or slow kinetics could possibly result in unacceptably high emissions. Thus, the reheat combustor design must balance the need for minimal excess oxygen with the need to oxidize the CO. This paper will describe the progress made to date in the design, fabrication, and simulation of a reheat combustor for an advanced steam generator system, and discuss planned experimental testing to be conducted in conjunction with NASA Glenn Research Center-Plumb Brook Station.

Crude oil steam distillation in steam flooding. Final report  

SciTech Connect

Steam distillation yields of sixteen crude oils from various parts of the United States have been determined at a saturated steam pressure of 200 psig. Study made to investigate the effect of steam pressure (200 to 500 psig) on steam distillation yields indicates that the maximum yields of a crude oil may be obtained at 200 psig. At a steam distillation correlation factor (V/sub w//V/sub oi/) of 15, the determined steam distillation yields range from 12 to 56% of initial oil volume for the sixteen crude oils with gravity ranging from 12 to 40/sup 0/API. Regression analysis of experimental steam distillation yields shows that the boiling temperature (simulated distillation temperature) at 20% simulated distillation yield can predict the steam distillation yields reasonably well: the standard error ranges from 2.8 to 3.5% (in yield) for V/sub w//V/sub oi/ < 5 and from 3.5 to 4.5% for V/sub w//V/sub oi/ > 5. The oil viscosity (cs) at 100/sup 0/F can predict the steam distillation yields with standard error from 3.1 to 4.3%. The API gravity can predict the steam distillation yields with standard error from 4.4 to 5.7%. Characterization factor is an unsatisfactory correlation independent variable for correlation purpose.

Water cooled steam jet  

DOE Patents (OSTI)

A water cooled steam jet for transferring fluid and preventing vapor lock, or vaporization of the fluid being transferred, has a venturi nozzle and a cooling jacket. The venturi nozzle produces a high velocity flow which creates a vacuum to draw fluid from a source of fluid. The venturi nozzle has a converging section connected to a source of steam, a diffuser section attached to an outlet and a throat portion disposed therebetween. The cooling jacket surrounds the venturi nozzle and a suction tube through which the fluid is being drawn into the venturi nozzle. Coolant flows through the cooling jacket. The cooling jacket dissipates heat generated by the venturi nozzle to prevent vapor lock.

Steam Condensation Induced Waterhammer  

E-Print Network (OSTI)

This is the type of waterhammer that kills people. It's initiating mechanism is much different than the image most engineers have of what causes waterhammer-- i.e. fast moving steam picking up a slug of condensate and hurling it downstream against an elbow or a valve. Condensation Induced Waterhammer can be 100 times more powerful than this type of waterhammer. Because it does not require flowing steam, it often occurs during relatively quiescent periods when operators least expect it. It's most often initiated by opening a valve, even a drain valve to remove condensate. The overpressure from an event can easily exceed 1000 psi. This is enough pressure to fracture a cast iron valve, blow out a steam gasket, or burst an accordion type expansion joint. And, in fact, failure of each of these components in separate condensation induced waterhammer accidents has resulted in operator fatalities. Operators and engineers need to understand this type of waterhammer so they can avoid procedures which can initiate it and designs which are susceptible to it.

Solar production of industrial process steam at Ore-Ida frozen-fried-potato plant  

DOE Green Energy (OSTI)

TRW is designing a system for the demonstration of the Solar Production of Industrial Process Steam. Included, besides the Conceptual Design, is an Environmental Impact Assessment and a System Safety Analysis report. The system as proposed and conceptualized consists of an array of 9520 square feet of parabolic trough concentrating solar energy collectors which generate pressurized hot water. The pressurized water is allowed to flash to steam at 300 psi (417/sup 0/F) and fed directly into the high pressure steam lines of the Ore-Ida Foods, Inc., processing plant in Ontario, Oregon. Steam is normally generated in the factory by fossil-fired boilers and is used by means of a steam-to-oil heat exchanger for the process of frying potatoes in their frozen food processing line. The high pressure steam is also cascaded down to 125 psi for use in other food processing operations. This solar system will generate 2 x 10/sup 6/ Btu/hr during peak periods of insolation. Steam requirements in the plant for frying potatoes are: 43 x 10/sup 6/ Btu/hr at 300 psi and 52 x 10/sup 6/ Btu/hr at the lower temperatures and pressures. The Ontario plant operates on a 24 hr/day schedule six days a week during the potato processing campaigns and five days a week for the remainder of the year. The seventh day and sixth day, respectively, use steam for cleanup operations. An analysis of the steam generated, based on available annual insolation data and energy utilized in the plant, is included.

Steam condensate leakage  

SciTech Connect

Argonne National Laboratory (ANL) is a multi-program research and development center owned by the United States Department of Energy and operated by the University of Chicago. The majority of the buildings on site use steam for heating and other purposes. Steam is generated from liquid water at the site`s central boiler house and distributed around the site by means of large pipes both above and below the ground. Steam comes into each building where it is converted to liquid condensate, giving off heat which can be used by the building. The condensate is then pumped back to the boiler house where it will be reheated to steam again. The process is continual but is not perfectly efficient. A substantial amount of condensate is being lost somewhere on site. The lost condensate has both economic and environmental significance. To compensate for lost condensate, makeup water must be added to the returned condensate at the boiler house. The water cost itself will become significant in the future when ANL begins purchasing Lake Michigan water. In addition to the water cost, there is also the cost of chemically treating the water to remove impurities, and there is the cost of energy required to heat the water, as it enters the boiler house 1000 F colder than the condensate return. It has been estimated that only approximately 60% of ANL`s steam is being returned as condensate, thus 40% is being wasted. This is quite costly to ANL and will become significantly more costly in the future when ANL begins purchasing water from Lake Michigan. This study locates where condensate loss is occurring and shows how much money would be saved by repairing the areas of loss. Shortly after completion of the study, one of the major areas of loss was repaired. This paper discusses the basis for the study, the areas where losses are occurring, the potential savings of repairing the losses, and a hypothesis as to where the unaccounted for loss is occurring.

Process for purifying geothermal steam  

DOE Patents (OSTI)

Steam containing hydrogen sulfide is purified and sulfur recovered by passing the steam through a reactor packed with activated carbon in the presence of a stoichiometric amount of oxygen which oxidizes the hydrogen sulfide to elemental sulfur which is adsorbed on the bed. The carbon can be recycled after the sulfur has been recovered by vacuum distillation, inert gas entrainment or solvent extraction. The process is suitable for the purification of steam from geothermal sources which may also contain other noncondensable gases.

High Efficiency Steam Electrolyzer  

SciTech Connect

A novel steam electrolyzer has been developed. In conventional electrolyzers, oxygen produced from electrolysis is usually released in the air stream. In their novel design, natural gas is used to replace air in order to reduce the chemical potential difference across the electrolyzer, thus minimizing the electrical consumption. The oxygen from the electrolysis is consumed in either a total oxidation or a partial oxidation reaction with natural gas. Experiments performed on single cells shown a voltage reduction as much as 1 V when compared to conventional electrolyzers. Using thin film materials and high performance cathode and anode, electrolysis could be done at temperatures as low as 700 C with electrolytic current as high as 1 A/cm{sup 2} at a voltage of 0.5 V only. The 700 C operating temperature is favorable to the total oxidation of natural gas while minimizing the need for steam that is otherwise necessary to avoid carbon deposition. A novel tubular electrolyzer stack has been developed. The system was designed to produce hydrogen at high pressures, taking advantage of the simplicity and high efficiency of the electrochemical compressors. A complete fabrication process was developed for making electrolyzer tubes with thin film coatings. A 100 W stack is being built.

Steam Basics: Use Available Data to Lower Steam System Cost  

E-Print Network (OSTI)

Industrial steam users recognize the need to reduce system cost in order to remain internationally competitive. Steam systems are a key utility that influence cost significantly, and represent a high value opportunity target. However, the quality of steam is often taken for granted, even overlooked at times. When the recent global recession challenged companies to remain profitable as a first priority, the result was that maintenance budgets were cut and long term cost reduction initiatives for steam systems set aside due to more pressing issues. One of the regrettable results of such actions is that knowledgeable personnel are re-assigned, retired, or released when necessary steam system cost reduction programs are eliminated. When the time arrives to refocus on long term cost reduction by improving the steam system, some programs may have to start from the beginning and a clear path forward may not be evident. New personnel are often tasked with steam improvements when the programs restart, and they may experience difficulty in determining the true key factors that can help reduce system cost. The urgency for lowering long term fuel use and reducing the cost of producing steam is near for each plant. Population growth and resultant global demand are inevitable, so the global economy will expand, production will increase, more fossil fuel energy will be needed, and that fuel will become scarce and more costly. Although fuel prices are low now, energy costs can be expected to trend significantly upward as global production and demand increase. Now is the time for plants to make certain that they can deliver high quality steam to process equipment at lowest system cost. There are three stages to help optimize plant steam for best performance at a low system cost; Phase 1: Manage the condensate discharge locations (where the steam traps & valves are located), Phase 2: Optimize steam-using equipment, and Phase 3: Optimize the entire steam system. This presentation will focus primarily on management of the condensate discharge locations (CDLs) and show sites how to use readily available data to more efficiently achieve goals; but will also provide insight into how the three stages interact to reduce system cost and improve process performance.

Evaluate deaerator steam requirements quickly  

Science Conference Proceedings (OSTI)

Steam plant engineers frequently have to perform energy balance calculations around the deaerator to estimate the steam required to preheat and deaerate the make-up water and condensate returns. This calculation involves solving two sets of equations, one for mass and the other for energy balance. Reference to steam tables is also necessary. However, with the help of this program written in BASIC, one can arrive at the make-up water and steam requirements quickly, without referring to steam tables. This paper shows the mass and energy balance equations for the deaerator. This paper gives the program listing. An number of condensate returns can be handled. An example illustrates the use of the program.

Further experimental studies of steam-propane injection to enhance recovery of Morichal oil  

E-Print Network (OSTI)

In 1998-1999, experimental research was conducted by Goite at Texas A&M University into steam-propane injection to enhance oil recovery from the Morichal field, Venezuela. Goite's results showed that, compared with steam injection alone, steam-propane injection accelerated oil production by as much as 23 % pore volume of steam injected (cold-water equivalent). The apparatus and procedure used in this study have been improved. Steam injection rate was kept constant at 5 cc/min (cold-water equivalent) for all runs. Four thermocouples were placed along the longitudinal axis of the cell to measure temperature profiles during injection. A new, more efficient method was developed to break emulsion in the produced sample. For four of the eight runs, consistent operating conditions were obtained by use of superheated steam, cell pressure of 50 psig, and identical insulation. Eight experimental runs were made in which the propane:steam mass ratios used were 0:100 (steam only), 1:100, 2.5:100, and 5:100. A run using 5:100 nitrogen: steam mass ratio was also made. The main findings of this research (derived from four runs with consistent operating conditions) are as follows. First, the propane:steam mass ratio of 5:100 accelerated the start and peak of oil production by 20 % and 13 % pore volume steam injected (cold-water equivalent), compared to steam injection alone. Second, oil recoveries for practical purposes are similar in all cases, 63 % - 70 % OOIP if average high and low values are taken. Third, the start of production is practically the same for 0:100 and 1:100 propane:steam ratio and for 5:100 nitrogen: steam ratio. In the latter case, the production peak is higher due to additional drive from nitrogen injection. Fourth, oil production acceleration in the 5:100 propane:steam case is probably caused by dry distillation in which light fractions of the oil partition into and are carried by the injected propane to lower the viscosity of the oil ahead of the steam front. Last, convective heat transfer at any of these low (5:100) ratios appears to be of secondary importance.

Flash vacuum pyrolysis of lignin model compounds  

DOE Green Energy (OSTI)

Despite the extensive research into the pyrolysis of lignin, the underlying chemical reactions that lead to product formation are poorly understood. Detailed mechanistic studies on the pyrolysis of biomass and lignin under conditions relevant to current process conditions could provide insight into utilizing this renewable resource for the production of chemicals and fuel. Currently, flash or fast pyrolysis is the most promising process to maximize the yields of liquid products (up to 80 wt %) from biomass by rapidly heating the substrate to moderate temperatures, typically 500{degrees}C, for short residence times, typically less than two seconds. To provide mechanistic insight into the primary reaction pathways under process relevant conditions, we are investigating the flash vacuum pyrolysis (FVP) of lignin model compounds that contain a {beta}-ether. linkage and {alpha}- or {gamma}-alcohol, which are key structural elements in lignin. The dominant products from the FVP of PhCH{sub 2}CH{sub 2}OPh (PPE), PhC(OH)HCH{sub 2}OPh, and PhCH{sub 2}CH(CH{sub 2}OH)OPh at 500{degrees}C can be attributed to homolysis of the weakest bond in the molecule (C-O bond) or 1,2-elimination. Surprisingly, the hydroxy-substituent dramatically increases the decomposition of PPE. It is proposed that internal hydrogen bonding is accelerating the reaction.

ULTRA-SUPERCRITICAL STEAM CORROSION  

SciTech Connect

Efficiency increases in fossil energy boilers and steam turbines are being achieved by increasing the temperature and pressure at the turbine inlets well beyond the critical point of water. To allow these increases, advanced materials are needed that are able to withstand the higher temperatures and pressures in terms of strength, creep, and oxidation resistance. As part of a larger collaborative effort, the Albany Research Center (ARC) is examining the steam-side oxidation behavior for ultrasupercritical (USC) steam turbine applications. Initial tests are being done on six alloys identified as candidates for USC steam boiler applications: ferritic alloy SAVE12, austenitic alloy Super 304H, the high Cr-high Ni alloy HR6W, and the nickel-base superalloys Inconel 617, Haynes 230, and Inconel 740. Each of these alloys has very high strength for its alloy type. Three types of experiments are planned: cyclic oxidation in air plus steam at atmospheric pressure, thermogravimetric ana lysis (TGA) in steam at atmospheric pressure, and exposure tests in supercritical steam up to 650 C (1202 F) and 34.5 MPa (5000 psi). The atmospheric pressure tests, combined with supercritical exposures at 13.8, 20.7, 24.6, and 34.5 MPa (2000, 3000, 4000, and 5000 psi) should allow the determination of the effect of pressure on the oxidation process.

Steam reformer with catalytic combustor  

DOE Patents (OSTI)

A steam reformer is disclosed having an annular steam reforming catalyst bed formed by concentric cylinders and having a catalytic combustor located at the center of the innermost cylinder. Fuel is fed into the interior of the catalytic combustor and air is directed at the top of the combustor, creating a catalytic reaction which provides sufficient heat so as to maintain the catalytic reaction in the steam reforming catalyst bed. Alternatively, air is fed into the interior of the catalytic combustor and a fuel mixture is directed at the top. The catalytic combustor provides enhanced radiant and convective heat transfer to the reformer catalyst bed.

GCFR steam generator conceptual design  

SciTech Connect

The gas-cooled fast reactor (GCFR) steam generators are large once-through heat exchangers with helically coiled tube bundles. In the GCFR demonstration plant, hot helium from the reactor core is passed through these units to produce superheated steam, which is used by the turbine generators to produce electrical power. The paper describes the conceptual design of the steam generator. The major components and functions of the design are addressed. The topics discussed are the configuration, operating conditions, design criteria, and the design verification and support programs.

Hot Dry Rock - Summary  

SciTech Connect

Hot Dry Rock adds a new flexibility to the utilization of geothermal energy. Almost always the approach has been to limit that utilization to places where there is a natural source of water associated with a source of heat. Actually, the result was that steam was mined. Clearly there are much larger heat resources available which lack natural water to transport that energy to the surface. Also, as is found in hydrothermal fields being mined for steam, the water supply finally gets used up. There is a strong motive in the existing capital investment to revitalize those resources. Techniques for introducing, recovering and utilizing the water necessary to recover the heat from below the surface of the earth is the subject of this session. Implicit in that utilization is the ability to forecast with reasonable accuracy the busbar cost of that energy to the utility industry. The added element of supplying the water introduces costs which must be recovered while still supplying energy which is competitive. Hot Dry Rock technology can supply energy. That has been proved long since. The basic barrier to its use by the utility industry has been and remains proof to the financial interests that the long term cost is competitive enough to warrant investment in a technology that is new to utility on-grid operations. As the opening speaker for this session states, the test that is underway will ''simulate the operations of a commercial facility in some ways, but it will not show that energy from HDR can be produced at a variety of locations with different geological settings''. Further, the Fenton Hill system is a research facility not designed for commercial production purposes, but it can give indications of how the system must be changed to provide economic HDR operations. And so it is that we must look beyond the long term flow test, at the opportunities and challenges. Proving that the huge HDR resources can be accessed on a worldwide scale must involve the construction of additional sites, preferably to the specifications of the now Federal geothermal community. These facilities will have to be engineered to produce and market energy at competitive prices. At the same time, we must not rest on our technological laurels, though they be many. Design and operational techniques have been conceived which could lead to improved economics and operations for HDR. These must be pursued and where merit is found, vigorously pursued. Accelerated research and development ought to include revolutionary drilling techniques, reservoir interrogation, and system modeling to assure the competitiveness and geographical diversity of applications of HDR. Much of this work will be applicable to the geothermal industry in general. More advanced research ought to include such innovations as the utilization of other operating fluids. Supercritical carbon dioxide and the ammonia/water (Kalina) cycle have been mentioned. But even as the near and more distant outlook is examined, today's work was reported in the HDR session. The start-up operations for the current test series at the Fenton Hill HDR Pilot Plant were described. The surface plant is complete and initial operations have begun. While some minor modifications to the system have been required, nothing of consequence has been found to impede operations. Reliability, together with the flexibility and control required for a research system were shown in the system design, and demonstrated by the preliminary results of the plant operations and equipment performance. Fundamental to the overall success of the HDR energy resource utilization is the ability to optimize the pressure/flow impedance/time relationships as the reservoir is worked. Significant new insights are still being developed out of the data which will substantially affect the operational techniques applied to new systems. However, again, these will have to be proved to be general and not solely specific to the Fenton Hill site. Nevertheless, high efficiency use of the reservoir without unintended reservoir grow

A study of wet-steam erosion of the disks and the rotor bosses or housings of turbines in thermal and nuclear power plants shows that the rate of wear does not depend on the diagrammed degree of moisture, but is determined by moisture condensing on the surfaces of the diaphragms and steam inlet components. Renovating the diaphragm seals as an assembly with condensate removal provides a manifold reduction in the erosion.

Steam distillation effect and oil quality change during steam injection  

SciTech Connect

Steam distillation is an important mechanism which reduces residual oil saturation during steam injection. It may be the main recovery mechanism in steamflooding of light oil reservoirs. As light components are distilled the residual (initial) oil, the residuum becomes heavier. Mixing the distilled components with the initial oil results in a lighter produced oil. A general method has been developed to compute steam distillation yield and to quantify oil quality changes during steam injection. The quantitative results are specific because the California crude data bank was used. But general principles were followed and calculations were based on information extracted from the DOE crude oil assay data bank. It was found that steam distillation data from the literature can be correlated with the steam distillation yield obtained from the DOE crude oil assays. The common basis for comparison was the equivalent normal boiling point. Blending of distilled components with the initial oil results in API gravity changes similar to those observed in several laboratory and field operations.

Simplify heat recovery steam generator evaluation  

SciTech Connect

Heat recovery steam generators (HRSGs) are widely used in process and power plants, refineries and in several cogeneration/combined cycle systems. They are usually designed for a set of gas and steam conditions but often operate under different parameters due to plant constraints, steam demand, different ambient conditions (which affect the gas flow and exhaust gas temperature in a gas turbine plant), etc. As a result, the gas and steam temperature profiles in the HRSG, steam production and the steam temperature differ from the design conditions, affecting the entire plant performance and economics. Also, consultants and process engineers who are involved in evaluating the performance of the steam system as a whole, often would like to simulate the performance of an HRSG under different gas flows, inlet gas temperature and analysis, steam pressure and feed water temperature to optimize the entire steam system and select proper auxiliaries such as steam turbines, condensers, deaerators, etc.

The Elimination of Steam Traps  

E-Print Network (OSTI)

How would you like to have a share of $154,000,000,000 a year? According to the Department of Energy that is roughly what was spent for creating steam in 1978. Steam generation accounts for fully one half of the industrial and commercial energy dollar. That figure could be reduced by 10-20% or more by the simple elimination of steam traps. Recent engineering developments show that steam traps can be eliminated. Documented results demonstrate that the retrofitting of existing facilities to alternative methods of condensate removal is simple and economically feasible, with paybacks of less than 12 months. Advantages obtained in the first year remain consistent for several years after conversion with virtual elimination of maintenance.

Computer Optimization of Steam Production  

E-Print Network (OSTI)

As fuel costs continued to rise sharply during the 1970' s, the staff at Exxon's Benicia Refinery realized there was a growing economic incentive to optimize the production of high pressure steam. A significant percentage of the Refinery's total energy is consumed in generating high pressure steam. Recently, a computer program was implemented to optimize high pressure steam production. The first challenge in developing the program was to provide reliable analog and digital instrumentation allowing simultaneous analog header control along with effective digital steam flow control. Once appropriate instrumentation became available, the effort focused on identifying the best approach for developing the computer control program. After screening several alternatives, it became apparent that we were dealing with an allocation problem which could be effectively handled with a linear program. The control program has performed well since it was commissioned. It has experienced a service factor of greater than 95% while reducing energy consumption of the boilers by over 500 million Btu's per day.

Heat Recovery Steam Generator Simulation  

E-Print Network (OSTI)

The paper discusses the applications of Heat Recovery Steam Generator Simulation. Consultants, plant engineers and plant developers can evaluate the steam side performance of HRSGs and arrive at the optimum system which matches the needs of the process plant, cogeneration or combined cycle plant. There is no need to design the HRSG per se and hence simulation is a valuable tool for anyone interested in evaluating the HRSG performance even before it is designed. It can also save a lot of time for specification writers as they need not guess how the steam side performance will vary with different gas/steam parameters. A few examples are given to show how simulation methods can be applied to real life problems.

Effect of non condensable gases on the performance of geothermal steam power systems  

DOE Green Energy (OSTI)

The influencce of dissolved carbon dioxide on the thermodynamic performance of geothermal steam systems is analyzed. The system is divided into its main component: the flash tank, the turbine, the condenser and the gas extraction system, and the effect of non condensables is studied for each. The effect of the noncondensable gas on the output of the whole system is deduced from its effect on the individual components. The analysis of actual systems is preceded by an analysis of an ideal system. The optimum condenser pressure for actual systems is obtained for different gas extraction system efficiencies. Economic considerations, however, are only qualitatively addressed.

Dynamic underground stripping: steam and electric heating for in situ decontamination of soils and groundwater  

SciTech Connect

A dynamic underground stripping process removes localized underground volatile organic compounds from heterogeneous soils and rock in a relatively short time. This method uses steam injection and electrical resistance heating to heat the contaminated underground area to increase the vapor pressure of the contaminants, thus speeding the process of contaminant removal and making the removal more complete. The injected steam passes through the more permeable sediments, distilling the organic contaminants, which are pumped to the surface. Large electrical currents are also applied to the contaminated area, which heat the impermeable subsurface layers that the steam has not penetrated. The condensed and vaporized contaminants are withdrawn by liquid pumping and vacuum extraction. The steam injection and electrical heating steps are repeated as necessary. Geophysical imaging methods can be used to map the boundary between the hot, dry, contamination-free underground zone and the cool, damp surrounding areas to help monitor the dynamic stripping process.

Steam gasification of wood in the presence of catalysts  

SciTech Connect

Catalytic steam gasification of wood, including sawdust, chipped forest slash, and mill shavings, is being investigated. Results of laboratory, process development unit (PDU), and feasibility studies illustrate attractive processes for conversion of wood to methanol and a substitute natural gas (SNG). Recent laboratory studies developed a long-lived alloy catalyst for generation of a methanol synthesis gas by steam gasification of wood. Modification of the PDU for operation at 10 atm (150 psia) is nearly complete. The modified PDU will be operated at the elevated pressure to confirm yields and design parameters used in process feasibility studies. Feasibility studies were completed on wood-to-methane (SNG) and wood-to-methanol plants with capacities of 2000 and 200 oven dried tons (1800 and 180 metric t) per day using catalytic gasification. The results showed that generation of methanol on the large scale is economically viable today while SNG generation is competitive with future prices.

ProSteam- A Structured Approach to Steam System Improvement  

E-Print Network (OSTI)

Optimal operation of site utility systems is becoming an increasingly important part of any successful business strategy as environmental, legislative and commercial pressures grow. A reliable steam model allows a clear understanding of the system and of any operational constraints. It can also be used to determine the true cost of improvement projects, relating any changes in steam demand back to purchased utilities (fuel, power, and make-up water) at the site boundary. Example projects could include improved insulation, better condensate return, increased process integration, new steam turbines or even the installation of gas-turbine based cogeneration. This approach allows sites to develop a staged implementation plan for both operational and capital investment projects in the utility system. Steam system models can be taken one step further and linked to the site DCS data to provide real-time balances and improve the operation of the system, providing an inexpensive but very effective optimizer. Such a model ensures that the steam system is set in the optimum manner to react to current utility demands, emissions regulations, equipment availability, fuel and power costs, etc. This optimization approach typically reduces day-to-day utility system operating costs by between 1% and 5% at no capital cost.

Solar production of industrial process steam. Phase III. Operation and evaluation of the Johnson and Johnson solar facility. Final report, January 1, 1980-March 31, 1981  

DOE Green Energy (OSTI)

A solar facility that generates 177/sup 0/C (350/sup 0/F) process steam has been designed and constructed by Acurex Corporation and has operated for 1 yr supplying steam to the Johnson and Johnson manufacturing plant in Sherman, Texas. The facility consists of 1068 m/sup 2/ (11,520 ft/sup 2/) of parabolic trough concentrating collectors, a 18,900 1 (5000 gal) flash boiler, and an 18.6 kW (25 hp) circulating pump. In the first year of operation the system was available 97 percent of the days, and with sufficient solar radiation available it operated 70 percent of the days during this period. The measured data showed that the collector field operated at an efficiency of 25.4 percent for the year, and that at least 75 percent of the energy reaching the flash boiler was delivered to the plant as steam. A total of 309,510 kg (682,400 lb) of steam was produced by the solar facility for the first year. An analysis of the data showed that the delivered energy was within 90 to 100 percent of the predicted value. The successful completion of the first year of operation has demonstrated the technical feasibility of generating industrial process steam with solar energy.

CARBON DIOXIDE CAPTURE FROM FLUE GAS USING DRY REGENERABLE SORBENTS  

SciTech Connect

This report describes research conducted between April 1, 2004 and June 30, 2004 on the preparation and use of dry regenerable sorbents for removal of carbon dioxide from flue gas. Support materials and supported sorbents were prepared by spray drying. Sorbents consisting of 20 to 50% sodium carbonate on a ceramic support were prepared by spray drying in batches of approximately 300 grams. The supported sorbents exhibited greater carbon dioxide capture rates than unsupported calcined sodium bicarbonate in laboratory tests. Preliminary process design and cost estimation for a retrofit application suggested that costs of a dry regenerable sodium carbonate-based process could be lower than those of a monoethanolamine absorption system. In both cases, the greatest part of the process costs come from power plant output reductions due to parasitic consumption of steam for recovery of carbon dioxide from the capture medium.

Dry cooling tower operating experience in the LOFT reactor  

SciTech Connect

A dry cooling tower has been uniquely utilized to dissipate heat generated in a small experimental pressurized water nuclear reactor. Operational experience revealed that dry cooling towers can be intermittently operated with minimal wind susceptibility and water hammer occurrences by cooling potential steam sources after a reactor scram, by isolating idle tubes from the external atmosphere, and by operating at relatively high pressures. Operating experience has also revealed that tube freezing can be minimized by incorporating the proper heating and heat loss prevention features.

Flash Memory Garbage Collection in Hard Real-Time Systems  

E-Print Network (OSTI)

Due to advances in capacity, speed, and economics, NAND-based flash memory technology is increasingly integrated into all types of computing systems, ranging from enterprise servers to embedded devices. However, due to its unpredictable up-date behavior and time consuming garbage collection mechanism, NAND-based flash memory is difficult to integrate into hard-real-time embedded systems. In this thesis, I propose a performance model for flash memory garbage collection that can be used in conjunction with a number of different garbage collection strategies. I describe how to model the cost of reactive (lazy) garbage collection and compare it to that of more proactive schemes. I develop formulas to assess the schedulability of hard real- time periodic task sets under simplified memory consumption models. Results show that I prove the proactive schemes achieve the larger maximum schedulable utilization than the traditional garbage collection mechanism for hard real-time systems in flash memory.

Exploring Shared Memory Protocols in FLASH  

SciTech Connect

ABSTRACT The goal of this project was to improve the performance of large scientific and engineering applications through collaborative hardware and software mechanisms to manage the memory hierarchy of non-uniform memory access time (NUMA) shared-memory machines, as well as their component individual processors. In spite of the programming advantages of shared-memory platforms, obtaining good performance for large scientific and engineering applications on such machines can be challenging. Because communication between processors is managed implicitly by the hardware, rather than expressed by the programmer, application performance may suffer from unintended communication communication that the programmer did not consider when developing his/her application. In this project, we developed and evaluated a collection of hardware, compiler, languages and performance monitoring tools to obtain high performance on scientific and engineering applications on NUMA platforms by managing communication through alternative coherence mechanisms. Alternative coherence mechanisms have often been discussed as a means for reducing unintended communication, although architecture implementations of such mechanisms are quite rare. This report describes an actual implementation of a set of coherence protocols that support coherent, non-coherent and write-update accesses for a CC-NUMA shared-memory architecture, the Stanford FLASH machine. Such an approach has the advantages of using alternative coherence only where it is beneficial, and also provides an evolutionary migration path for improving application performance. We present data on two computations, RandomAccess from the HPC Challenge benchmarks and a forward solver derived from LS-DYNA, showing the performance advantages of the alternative coherence mechanisms. For RandomAccess, the non-coherent and write-update versions can outperform the coherent version by factors of 5 and 2.5, respectively. In LS-DYNA, we obtain improvements of 18% on average using the non-coherent version. We also present data on the SpecOMP benchmarks, showing that the protocols have a modest overhead of less than 3% in applications where the alternative mechanisms are not needed. In addition to the selective coherence studies on the FLASH machine, in the last six months of this project ISI performed research on compiler technology for the transactional memory (TM) programming model being developed at Stanford. As part of this research ISI developed a compiler that recognizes transactional memory pragmas and automatically generates parallel code for the TM programming model

Distribution of fluid phases within the steam zone in steam injection processes  

SciTech Connect

The saturation distribution of steam, water, and oil within the steam zone in a steam injection process at constant injection rates is examined. It is shown theoretically that for typical values of injection parameters the oil saturation in the steam zone rapidly reaches its residual value at steam zone conditions. This result, which corroborates previous experimental evidence, is a consequence of the relatively fast changes in phase saturations compared to the rate of the advance of the steam front. Explicit expressions for the steam saturation distribution are obtained. It is shown that the average steam saturation is a slightly decreasing function of time and approaches a limiting value which is a nearly constant fraction of the steam saturation at the injection point. This result provides theoretical justification for the often made assumption of constant average steam saturation in steam injection calculations.

IMPROVEMENTS IN STEAM GENERATING PLANT AND AN IMPROVED METHOD OF GENERATING STEAM  

SciTech Connect

A steam generating plant, designed for heat transfer from a liquid metal (potassium, sodium, or their alloy) with reduced danger of explosion, is based on the fact that, if steam (especially superheated) rather than water contacts the liquid metal, the risk of explosion is much reduced. In this plant steam is superheated by heat transfer from liquid metal, the steam bsing generated by heat transfer between the superheated steam and water. Diagrams are given for the plant, which comprises a series of heat exchangers in which steam is superheated; part of the superheated steam is recycled to convert water into steam. Apart from the danger of a steam--liquid metal contact, the main danger is that the superheated steam might cool, coming to the saturated condition; this danger can be averted by setting up mceans for detecting low steam temperatures.

Steam generation in line-focus solar collectors: a comparative assessment of thermal performance, operating stability, and cost issues  

DOE Green Energy (OSTI)

The engineering and system benefits of using direct steam (in situ) generation in line-focus collectors are assessed. The major emphasis of the analysis is a detailed thermal performance comparison of in situ systems (which utilize unfired boilers). The analysis model developed for this study is discussed in detail. An analysis of potential flow stability problems is also provided along with a cursory cost analysis and an assessment of freeze protection, safety, and control issues. Results indicated a significant thermal performance advantage over the more conventional oil and flash systems and the flow stability does not appear to be a significant problem. In particular, at steam temperatures of 220/sup 0/C (430/sup 0/F) under the chosen set of assumptions, annual delivered energy predictions indicate that the in situ system can deliver 15% more energy than an oil system and 12% more energy than a flash system, with all of the systems using the same collector field. Further, the in situ system may result in a 10% capital cost reduction. Other advantages include improvement in simpler control when compared with flash systems, and fluid handling and safety enhancement when compared with oil systems.

Generating Steam by Waste Incineration  

E-Print Network (OSTI)

Combustible waste is a significant source of steam at the new John Deere Tractor Works assembly plant in Waterloo, Iowa. The incinerators, each rated to consume two tons of solid waste per hour, are expected to provide up to 100 percent of the full production process steam requirements. The waste incineration system consists of a wood dunnage shredder, two Skid-Steer Loaders for incinerator charging, two incinerators, and a wet ash conveyor. The equipment is housed in a building with floor space to accommodate loads of combustible waste delivered for incineration. Incombustible material is segregated at the source. A review of operational experience and the results of a study on actual steam production costs will be presented with the intent that others will be able to use the information to advance the state of the art of high volume controlled air waste incineration.

Fast fluidized bed steam generator  

DOE Patents (OSTI)

A steam generator in which a high-velocity, combustion-supporting gas is passed through a bed of particulate material to provide a fluidized bed having a dense-phase portion and an entrained-phase portion for the combustion of fuel material. A first set of heat transfer elements connected to a steam drum is vertically disposed above the dense-phase fluidized bed to form a first flow circuit for heat transfer fluid which is heated primarily by the entrained-phase fluidized bed. A second set of heat transfer elements connected to the steam drum and forming the wall structure of the furnace provides a second flow circuit for the heat transfer fluid, the lower portion of which is heated by the dense-phase fluidized bed and the upper portion by the entrained-phase fluidized bed.

Steam Boiler Control Specification Problem:  

E-Print Network (OSTI)

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

FEMP-FTA--Steam Trap Performance Assessment  

Energy.gov (U.S. Department of Energy (DOE)) Indexed Site

Steam Trap Function Steam Trap Function Steam traps are automatic valves used in every steam system to remove conden- sate, air, and other non-condensable gases while preventing or minimizing the passing of steam. If condensate is allowed to collect, it reduces the flow capacity of steam lines and the thermal capacity of heat transfer equipment. In addition, excess condensate can lead to "water hammer," with potentially destructive and dangerous results. Air that remains after system startup reduces steam pressure and temperature and may also reduce the thermal capacity of heat transfer equipment. Non-condensable gases, such as oxygen and carbon dioxide, cause corrosion. Steam that passes through the trap provides no heating ser- vice. This effectively reduces the heating capacity

A typical embodiment of the invention provides a combination feedwater and "cooldown" water spray head that is centrally disposed in the lower portion of a nuclear power plant steam drum. This structure not only discharges the feedwater in the hottest part of the steam drum, but also increases the time required for the feedwater to reach the steam drum shell, thereby further increasing the feedwater temperature before it contacts the shell surface, thus reducing thermal shock to the steam drum structure.

Materials Performance in USC Steam  

SciTech Connect

The proposed steam inlet temperature in the Advanced Ultra Supercritical (A-USC) steam turbine is high enough (760 C) that traditional turbine casing and valve body materials such as ferritic/martensitic steels will not suffice due to temperature limitations of this class of materials. Cast versions of several traditionally wrought Ni-based superalloys were evaluated for use as casing or valve components for the next generation of industrial steam turbines. The full size castings are substantial: 2-5,000 kg each half and on the order of 100 cm thick. Experimental castings were quite a bit smaller, but section size was retained and cooling rate controlled to produce equivalent microstructures. A multi-step homogenization heat treatment was developed to better deploy the alloy constituents. The most successful of these cast alloys in terms of creep strength (Haynes 263, Haynes 282, and Nimonic 105) were subsequently evaluated by characterizing their microstructure as well as their steam oxidation resistance (at 760 and 800 C).

Performance Analysis of a Flash-Crowd Management System  

E-Print Network (OSTI)

Dr. Guillaume PierreFlash-crowds are a growing obstacle to the further expansion of the Internet. One of the solutions to this problem is to replicate the most popular documents to different web servers and to redirect client requests to these replicas. In this thesis we present a performance analysis of a flash-crowd management system based on RaDaR. We adjust the architecture of RaDaR to focus more on adaptability rather than scalability, to give the system a better chance against a flash-crowd by using algorithms from another system by the same authors, ACDN. Because existing benchmarks do not show realistic behavior, we first propose our own synthetic benchmark. Finally we use the benchmark tool to replay requests from a trace of an actual flash-crowd. Our results are three-fold: first we show how to dimension a RaDaR-like system. Second, we demonstrate based on a synthetic benchmark as well as a trace-based benchmark that the RaDaR-like system adjusts to a flash-crowd in a timely and efficient fashion. Finally, we identify an inherent instability in the replica placement

Flash pyrolysis of oil shale with various gases  

DOE Green Energy (OSTI)

The flash pyrolysis of Colorado Oil Shale with methane at a temperature of 800/sup 0/C and pressure of 500 psi appears to give the highest yield of hydrocarbon gas and liquid followed by hydrogen and lowest with helium. In the methane pyrolysis over 54.5% of the carbon in the kerogen is converted to ethylene and benzene. The flash pyrolysis with hydrogen (flash hydropyrolysis) of the oil shale at increasing temperatures showed a rapidly increasing amount of methane formed and a decrease in ethane formation, while the BTX (benzene mainly) yield remained at approximately 10%. At 950/sup 0/C and 500 psi almost all (97.0%) of the carbon in the kerogen is converted to liquid and gaseous hydrocarbons. Experiments with a mixture of a New Mexico sub-bituminous coal and oil shale under flash hydropyrolysis and methane pyrolysis conditions indicated higher yields of methane and ethylene and slightly lower yields of benzene than predicted by partial additive calculations. These exploratory experiments appear to be of sufficient interest to warrant a fuller investigation of the interaction of the natural resources, oil shale, coal and natural gas under flash pyrolysis conditions.

Multi-Level Bitmap Indexes for Flash Memory Storage  

SciTech Connect

Due to their low access latency, high read speed, and power-efficient operation, flash memory storage devices are rapidly emerging as an attractive alternative to traditional magnetic storage devices. However, tests show that the most efficient indexing methods are not able to take advantage of the flash memory storage devices. In this paper, we present a set of multi-level bitmap indexes that can effectively take advantage of flash storage devices. These indexing methods use coarsely binned indexes to answer queries approximately, and then use finely binned indexes to refine the answers. Our new methods read significantly lower volumes of data at the expense of an increased disk access count, thus taking full advantage of the improved read speed and low access latency of flash devices. To demonstrate the advantage of these new indexes, we measure their performance on a number of storage systems using a standard data warehousing benchmark called the Set Query Benchmark. We observe that multi-level strategies on flash drives are up to 3 times faster than traditional indexing strategies on magnetic disk drives.

Flash photolysis of rhodopsin in the cat retina  

SciTech Connect

The bleaching of rhodopsin by short-duration flashes of a xenon discharge lamp was studied in vivo in the cat retina with the aid of a rapid, spectral-scan fundus reflectometer. Difference spectra recorded over a broad range of intensities showed that the bleaching efficacy of high-intensity flashes was less than that of longer duration, steady lights delivering the same amount of energy. Both the empirical results and those derived from a theoretical analysis of flash photolysis indicate that, under the conditions of these experiments, the upper limit of the flash bleaching of rhodopsin in cat is approximately 90%. Although the fact that a full bleach could not be attained is attributable to photoreversal, i.e., the photic regeneration of rhodopsin from its light-sensitive intermediates, the 90% limit is considerably higher than the 50% (or lower) value obtained under other experimental circumstances. Thus, it appears that the duration (approximately 1 ms) and spectral composition of the flash, coupled with the kinetic parameters of the thermal and photic reactions in the cat retina, reduce the light-induced regeneration of rhodopsin to approximately 10%.

Freeze drying method  

DOE Patents (OSTI)

The present invention provides methods and apparatus for freeze drying in which a solution, which can be a radioactive salt dissolved within an acid, is frozen into a solid on vertical plates provided within a freeze drying chamber. The solid is sublimated into vapor and condensed in a cold condenser positioned above the freeze drying chamber and connected thereto by a conduit. The vertical positioning of the cold condenser relative to the freeze dryer helps to help prevent substances such as radioactive materials separated from the solution from contaminating the cold condenser. Additionally, the system can be charged with an inert gas to produce a down rush of gas into the freeze drying chamber to also help prevent such substances from contaminating the cold condenser.

Steam cooling system for a gas turbine  

SciTech Connect

The steam cooling circuit for a gas turbine includes a bore tube assembly supplying steam to circumferentially spaced radial tubes coupled to supply elbows for transitioning the radial steam flow in an axial direction along steam supply tubes adjacent the rim of the rotor. The supply tubes supply steam to circumferentially spaced manifold segments located on the aft side of the 1-2 spacer for supplying steam to the buckets of the first and second stages. Spent return steam from these buckets flows to a plurality of circumferentially spaced return manifold segments disposed on the forward face of the 1-2 spacer. Crossover tubes couple the steam supply from the steam supply manifold segments through the 1-2 spacer to the buckets of the first stage. Crossover tubes through the 1-2 spacer also return steam from the buckets of the second stage to the return manifold segments. Axially extending return tubes convey spent cooling steam from the return manifold segments to radial tubes via return elbows.

Hydrogen production by high-temperature steam gasification of biomass and coal  

Science Conference Proceedings (OSTI)

High-temperature steam gasification of paper, yellow pine woodchips, and Pittsburgh bituminous coal was investigated in a batch-type flow reactor at temperatures in the range of 700 to 1,200{sup o}C at two different ratios of steam to feedstock molar ratios. Hydrogen yield of 54.7% for paper, 60.2% for woodchips, and 57.8% for coal was achieved on a dry basis, with a steam flow rate of 6.3 g/min at steam temperature of 1,200{sup o}C. Yield of both the hydrogen and carbon monoxide increased while carbon dioxide and methane decreased with the increase in gasification temperature. A 10-fold reduction in tar residue was obtained at high-temperature steam gasification, compared to low temperatures. Steam and gasification temperature affects the composition of the syngas produced. Higher steam-to-feedstock molar ratio had negligible effect on the amount of hydrogen produced in the syngas in the fixed-batch type of reactor. Gasification temperature can be used to control the amounts of hydrogen or methane produced from the gasification process. This also provides mean to control the ratio of hydrogen to CO in the syngas, which can then be processed to produce liquid hydrocarbon fuel since the liquid fuel production requires an optimum ratio between hydrogen and CO. The syngas produced can be further processed to produce pure hydrogen. Biomass fuels are good source of renewable fuels to produce hydrogen or liquid fuels using controlled steam gasification.

High-Efficiency Steam Electrolyzer  

SciTech Connect

We are developing a novel high-efficiency, high-temperature steam electrolyzer. Although water or steam electrolysis is well known to be one of the cleanest ways to produce hydrogen, widespread utilization is hindered by high operational costs because of high electricity consumption. To decrease the electrical power input requirements in electrolysis, our approach uses natural gas as an anode depolarizer. This approach essentially replaces one unit of electricity with one equivalent-energy unit of natural gas at much lower cost. The direct use of natural gas on the electrolyzer enables very high system efficiency with respect to primary energy. Experiments performed on single cells have shown a voltage reduction as much as 1 V when compared to conventional electrolyzers. System efficiency has been estimated to be 50 to 80%, depending on the electrolytic current. A 200-W prototype unit is being developed.

A nuclear power plant is designed using a heavy-watermoderated, steam- cooled reactor. In this plant, feed water is heated by the moderator and reactor steam to form feed steam, which is then superheated by superheated reactor steam and expanded through a nozzle. The feed steam issuing from the nozzie has added to it the superheated reactor steam, and the resulting steam is compressed, heated further in the reactor, and part of it passed to the turbine.

Preliminary results of thermal igniter experiments in H/sub 2/-air-steam environments. [PWR; BWR  

DOE Green Energy (OSTI)

Thermal igniters (glow plugs), proposed by the Tennessee Valley Authority for intentional ignition of hydrogen in nuclear reactor containment, have been tested for functionability in mixtures of air, hydrogen, and steam. Test environments included 6% to 16% hydrogen concentrations in air, and 8%, 10%, and 12% hydrogen in mixtures with 30% and 40% steam fractions. All were conducted in a 10.6 ft/sup 3/ insulated pressure vessel. For all of these tests the glow plug successfully initiated combustion. Dry air/hydrogen tests exhibited a distinct tendency for complete combustion at hydrogen concentrations between 8% and 9%. Steam suppressed both peak pressures and completeness of combustion. No combustion could be initiated at or above a 50% steam fraction. Circulation of the mixture with a fan increased the completeness of combustion. The glow plug showed no evidence of performance degradation throughout the program.

The economics of repowering steam turbines  

SciTech Connect

Repowering is defined as displacing steam presently generated in an existing fossil fuel fired boiler with a gas turbine-heat recovery steam generator (HRSG) system. The steam generated in the HRSG is expanded in the existing steam turbine generator. Repowering advantages include a significant increase in power output at an improved heat rate relative to the base value for the existing steam turbine cycle being repowered. In addition, the reduction in emissions can be advantageous in most locations. This paper discusses application and economic considerations associated with repowering. In addition, an illustration will show how repowering coal fired steam turbine systems may prove economic relative to retrofit scrubbers and/or low sulfur coal fuel substitution that may be part of the forthcoming acid rain legislation.

Steam System Optimization : A Case Study  

E-Print Network (OSTI)

The steam system optimization (generation, distribution, use and condensate return) offers a large opportunity for action to comply with the new levels of energy efficiency standards. Superior design and improved maintenance practices are the two main sources of savings in steam systems. Increased competition no longer permits an industry to survive with energy waste that could be eliminated. This paper highlights the study findings of the steam system in a plant from the Food industry. The steam system operates with an annual budget of $1.9 million. Normal steam demand ranges between 80,000 to 85,000 lb/hr. The steam system analysis identified energy savings worth $270,000 per year. The optimization measures were in two categories: No cost/low cost optimizations that can be done through a better maintenance and improved operating condition Major improvements that require a significant investment, and includes the modification of the process and major equipment.
