Steam Oxidation of Fossil Power Plant Materials: Collaborative Research to Enable Advanced Steam Power Cycles  

DOE Public Access Gateway for Energy & Science Beta (PAGES Beta)

Research into improved materials systems and associated manufacturing and reliability issues is a major part of initiatives to produce cleaner and cheaper energy systems in the UK and the USA. Under the auspices of a Memorandum of Understanding on Energy R&D, a work programme concerned with steam oxidation has been conducted. The focus was on the generation of definitive information regarding the oxidation behaviour in steam of current and developmental ferritic steels, austenitic steels, and nickelbased alloys required to enable advanced steam power cycles. The results were intended to provide a basis for quantifying the rate of metal loss expected under advanced steam cycle conditions, as well as understanding of the evolution of oxide scale morphologies with time and temperature to identify features that could influence scale exfoliation characteristics. This understanding and acquired data were used to develop and validate models of oxide growth and loss by exfoliation. This paper provides an overview of the activity and highlights a selection of the results coming from the programme.

Improving steam turbine efficiency  

SciTech Connect (OSTI)

This paper describes the condition of a significant number of fossil steam turbines operating in the United States and the maintenance practices used to improve their performance. Through the use of steam path audits conducted by the authors` company and by several utilities, a large data base of information on turbine heat rate, casing efficiency, and maintenance practices is available to help the power generation industry understand how different maintenance practices and steam path damage impact turbine performance. The data base reveals that turbine cycle heat rate is typically 5.23% poorer than design just prior to major outages. The degraded condition of steam turbines presents an opportunity for utilities to improve heat rate and reduce emissions without increasing fuel costs. The paper describes what losses typically contribute to the 5.23% heat rate degradation and how utilities can recover steam turbine performance through maintenance actions aimed at improving steam path efficiency.

Waste biomass from production process co-firing with coal in a steam boiler to reduce fossil fuel consumption: A case study  

Science Journals Connector (OSTI)

Abstract Waste biomass is always generated during the production process in industries. The ordinary way to get rid of the waste biomass is to send them to landfill or burn it in the open field. The waste may potentially be used for co-firing with coal to save fossil fuel consumption and also reduce net carbon emissions. In this case study, the bio-waste from a Nicotiana Tabacum (NT) pre-treatment plant is used as the biomass to co-fire with coal. The samples of NT wastes were analysed. It was found that the wastes were of the relatively high energy content which were suitable for co-firing with coal. To investigate the potential and benefits for adding NT wastes to a Fluidised Bed Combustion (FBC) boiler in the plant, detailed modelling and simulation are carried out using the European Coal Liquefaction Process Simulation and Evaluation (ECLIPSE) process simulation package. The feedstock blending ratios of NT waste to coal studied in this work are varied from 0% to 30%. The results show that the addition of NT wastes may decrease the emissions of CO2 and \\{SOx\\} without reducing the boiler performance.

ULTRA-SUPERCRITICAL STEAM CORROSION  

SciTech Connect (OSTI)

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.

Draft environmental impact statement for construction and operation of the proposed Bangor Hydro-Electric Company`s second 345-kV transmission tie line to New Brunswick  

SciTech Connect (OSTI)

This Draft Environmental Impact Statement (DEIS) was prepared by the US Department of Energy (US DOE). The proposed action is the issuance of Presidential Permit PP-89 by DOE to Bangor Hydro-Electric Company to construct and operate a new international transmission line interconnection to New Brunswick, Canada that would consist of an 83.8 mile (US portion), 345-kilovolt (kV) alternating current transmission line from the US-Canadian border at Baileyville, Maine to an existing substation at Orrington, Maine. The principal environmental impacts of the construction and operation of the transmission line would be incremental in nature and would include the conversion of forested uplands (mostly commercial timberlands) and wetlands to right-of-way (small trees, shrubs, and herbaceous vegetation). The proposed line would also result in localized minor to moderate visual impacts and would contribute a minor incremental increase in the exposure of some individuals to electromagnetic fields. This DEIS documents the purpose and need for the proposed action, describes the proposed action and alternatives considered and provides a comparison of the proposed and alternatives routes, and provides detailed information on analyses of the environmental consequences of the proposed action and alternatives, as well as mitigative measures to minimize impacts.

Evaluation of fossil plants versus hydro plants for load frequency control  

SciTech Connect (OSTI)

The economics of using hydroplants with Francis turbines or fossil plants for load frequency control are evaluated. Using data from the TVA Gallatin steam plant and the TVA Cherokee, Wilson, and Fontana hydroplants, a cost comparison of different modes of operation for load frequency control was performed considering two plants at a time. The results showed that when the fossil plant was used for load frequency control instead of a hydro plant a lower system generation cost was incurred. Dynamic responses of fossil and hydro units, improved controls for fossil plants, and maneuvering costs of the Gallatin plant are also considered.

During a turbine outage, plant performance and maintenance staff make and prioritize repair decisions within tight time and budget constraints. This paper describes how Georgia Power identifies performance losses of degraded components in the steam path and determines their impact on heat rate. Turbine performance is assessed by a steam path audit program that Encotech has developed and make available to utilities. Georgia Power has conducted several operating tests that give good correlation with audit results. Georgia Power uses the audit information to make the most cost-effective repairs to maintain a low heat rate and to reduce emissions. The Clean Air Act presents electric utilities with the challenge of reducing emissions from fossil plants in the most cost-effective way possible. Meeting the stack emissions limitations often translates to large capital expenditures and increased cycle heat rate. One resource the electric utilities have to reduce the costly impact of compliance with the Clean Air Act is control over the efficiency of their steam turbines.

Steam Oxidation of Advanced Steam Turbine Alloys  

SciTech Connect (OSTI)

Power generation from coal using ultra supercritical steam results in improved fuel efficiency and decreased greenhouse gas emissions. Results of ongoing research into the oxidation of candidate nickel-base alloys for ultra supercritical steam turbines are presented. Exposure conditions range from moist air at atmospheric pressure (650°C to 800°C) to steam at 34.5 MPa (650°C to 760°C). Parabolic scale growth coupled with internal oxidation and reactive evaporation of chromia are the primary corrosion mechanisms.

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.

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.

Geothermal steam quality testing  

SciTech Connect (OSTI)

Geothermal steam quality and purity have a significant effect on the operational efficiency and life of geothermal steam turbines and accessory equipment. Poor steam processing can result in scaled nozzles/blades, erosion, corrosion, reduced utilization efficiency, and early fatigue failures accelerated by stress corrosion cracking (SCC). Upsets formed by undetected slugs of liquid entering the turbine can cause catastrophic failure. The accurate monitoring and determination of geothermal steam quality/purity is intrinsically complex which often results in substantial errors. This paper will review steam quality and purity relationships, address some of the errors, complexities, calibration and focus on: thermodynamic techniques for evaluating and monitoring steam quality by use of the modified throttling calorimeters.

Almost everyone “knows” that steam is visible. After all one can see the cloud of white issuing from the spout of a boiling tea kettle. In reality steam is the gaseous phase of water and is invisible. What you see is light scattered from the tiny droplets of water that are the result of the condensation of the steam as its temperature falls below 100 °C (under standard conditions).

Steam reforming analyzed  

SciTech Connect (OSTI)

This paper reports that maximum steam reformer operation without excessive coking reactions requires careful control of thermodynamic and kinetic conditions. Regardless of the syngas-based feedstock composition, carbon formation problems can be avoided while increasing reformer CO or H{sub 2} production. Steam reforming technology is best understood via: Primary steam reformer developments, Kinetics of methane steam reforming, Simulation of an industrial steam/CO{sub 2} reformer, Example conditions (steam/CO{sub 2} reforming), Thermodynamic approach (minimum to steam ratio). Hydrogen and carbon monoxide are two of the most important building blocks in the chemical industry. Hydrogen is mainly used in ammonia and methanol synthesis and petroleum refining. Carbon monoxide is used to produce pains, plastics, foams, pesticides and insecticides, to name a few. Production of H{sub 2} and CO is usually carried out by the following processes: Steam reforming (primary and secondary) of hydrocarbons, Partial oxidation of hydrocarbons, Coal gasification. Coal gasification and partial oxidation do not use catalysts and depend on partial combustion of the feedstock to internally supply reaction heat. Secondary (autothermal) reforming is a type of steam reforming that also uses the heat of partial combustion but afterwards uses a catalyst of promote the production of hydrogen and CO.

Diagnostics based on thermodynamic analysis of performance of steam turbines: case histories  

SciTech Connect (OSTI)

The purpose of this paper is to describe some types of failures which have occurred with the ENEL stock of fossil-fuel steam turbines over the last 5--7 years. This paper also presents the corresponding thermodynamic analysis of turbine parameters which permitted failure diagnosis and pre-scheduled opening of the turbine. The examined failures concern: in-service rupture of the bell seal retainer nut between the SH steam inlet sleeves and the inner HP/IP cylinder, on turbines with a main steam inlet system with bell seals; incorrect assembly of pressure seal rings between steam inlet sleeves and the inner cylinder on turbines with a main steam inlet system with pressure seal rings during a scheduled outage; and steam flow path restriction in IP turbine inlet. Thermodynamic failure analysis and the subsequent analysis of turbine damage (mechanical and financial) enabled condition-based maintenance operations to be carried out.

Fossil fuel furnace reactor  

DOE Patents [OSTI]

A fossil fuel furnace reactor is provided for simulating a continuous processing plant with a batch reactor. An internal reaction vessel contains a batch of shale oil, with the vessel having a relatively thin wall thickness for a heat transfer rate effective to simulate a process temperature history in the selected continuous processing plant. A heater jacket is disposed about the reactor vessel and defines a number of independent controllable temperature zones axially spaced along the reaction vessel. Each temperature zone can be energized to simulate a time-temperature history of process material through the continuous plant. A pressure vessel contains both the heater jacket and the reaction vessel at an operating pressure functionally selected to simulate the continuous processing plant. The process yield from the oil shale may be used as feedback information to software simulating operation of the continuous plant to provide operating parameters, i.e., temperature profiles, ambient atmosphere, operating pressure, material feed rates, etc., for simulation in the batch reactor.

Power-plant operators are reducing maintenance costs of their aging steam turbines by using wire-arc spray coating and shot peening to prolong the service life of components, and by replacing outmoded bearings and seals with newer designs. Steam-turbine operators are pressed with the challenge of keeping their aging machines functioning in the face of wear problems that are exacerbated by the demand for higher efficiencies. These problems include intense thermal cycling during both start-up and shutdown, water particles in steam and solid particles in the air that pit smooth surfaces, and load changes that cause metal fatigue.

Flow Characteristics Analysis of Widows' Creek Type Control Valve for Steam Turbine Control  

SciTech Connect (OSTI)

The steam turbine converts the kinetic energy of steam to mechanical energy of rotor blades in the power conversion system of fossil and nuclear power plants. The electric output from the generator of which the rotor is coupled with that of the steam turbine depends on the rotation velocity of the steam turbine bucket. The rotation velocity is proportional to the mass flow rate of steam entering the steam turbine through valves and nozzles. Thus, it is very important to control the steam mass flow rate for the load following operation of power plants. Among various valves that control the steam turbine, the control valve is most significant. The steam flow rate is determined by the area formed by the stem disk and the seat of the control valve. While the ideal control valve linearly controls the steam mass flow rate with its stem lift, the real control valve has various flow characteristic curves pursuant to the stem lift type. Thus, flow characteristic curves are needed to precisely design the control valves manufactured for the operating conditions of nuclear power plants. OMEGA (Optimized Multidimensional Experiment Geometric Apparatus) was built to experimentally study the flow characteristics of steam flowing inside the control valve. The Widows' Creek type control valve was selected for reference. Air was selected as the working fluid in the OMEGA loop to exclude the condensation effect in this simplified approach. Flow characteristic curves were plotted by calculating the ratio of the measured mass flow rate versus the theoretical mass flow rate of the air. The flow characteristic curves are expected to be utilized to accurately design and operate the control valve for fossil as well as nuclear plants. (authors)

Methane-steam reforming  

SciTech Connect (OSTI)

The literature relating to the kinetics of methane-steam reforming involving integral and differential reactor data, porous nickel catalysts and nickel foil, and data over large ranges of temperature (500 to 1700/sup 0/F), pressure (0.01 to 50 atm), and intrinsic catalyst activities (200,000-fold) was reviewed. A simple reversible first-order kinetic expression for the steam-methane reaction appears to be applicable throughout the operable region of steam-to-carbon ratios. Internal pore diffusion limitation on the conversion rate, due to catalyst size and/or intrinsic catalyst activity and total operating pressure was underlined. S-shaped Arrhenium plots (changing activation energy) are obtained when steam reforming is conducted over a temperature range sufficient to produce intrinsic kinetics (low temperature, inactive catalyst, or small catalyst size), pore diffusional limitations, and reaction on the outside surface. Homogeneous gas-phase kinetics appear to contribute only at relatively high temperature (1400/sup 0/F). In steam reforming, the water-gas shift reaction departs from its equilibrium position, especially at low methane conversion level. A general correlation of approach to water-gas shift equilibration as a function of conversion level only was indicated. (DP) 18 figures, 6 tables.

Advanced steam parameters for pulverized coal fired boilers  

SciTech Connect (OSTI)

After the enormous efforts made in the eighties towards minimization of pollutant concentration in flue gases from power stations, public attention today has turned increasingly toward CO{sub 2} emissions from fossil fuel fired plants. This interest has, in turn, renewed interest in increasing the efficiency of thermal power plants, as this approach is by far the most practical means of reducing the specific CO{sub 2} emission rate. The Rankine steam cycle is the workhorse of the power industry. However, the steam power cycle is often regarded as having reached a maximum practical efficiency, and development effort has shifted to indirect fired cycles. In reality, Rankine cycle efficiencies equivalent to the combined Brayton/Rankine cycles are possible, and may be economically practical. The development work which would allow such steam cycle efficiencies to be realized has been limited in recent years, due to low growth rates, falling energy prices, and tying up of investment funds in environmental control equipment. This paper presents a short survey of the application for advanced steam parameters in power generation and discusses critical areas in more detail. A program undertaken by a consortium of European manufacturers and EC governments for the advancement of steam cycle efficiency is described.

Steam management in composite mature steam floods, Midway Sunset field  

SciTech Connect (OSTI)

Vogel noted that oil production rates in many steam floods are not predictable from steam injection rates and must be estimated on some other basis. He presented a conservative method, based on simple models assuming instantaneous steam overlay, to calculate heat requirements once the oil rate is known. By more accurately describing the reservoir being flooded and the steam flood process, Vogel`s method was refined resulting in significant steam savings for SWEPI`s leasehold in the northern part of the Midway Sunset field. Analytical expressions are presented for (1) the heat required to support a steam chest descending into an oil column, (2) the heating of a cap or base rock already partially heated by an adjacent steam flood and (3) the heating of a cap or base rock which is exposed to a uniformly growing steam zone. A method is also described to operate a mature steam flood at a constant oil steam ratio while scavenging some heat stored in the steam zone.

Diagnostics based on thermodynamic analysis of performance of steam turbines: Case histories  

SciTech Connect (OSTI)

The purpose of this paper is to describe some types of failures which have occurred with the ENEL stock of fossil-fuel steam turbines over the last 5--7 years. This paper also presents the corresponding thermodynamic analysis of turbine parameters which permitted failure diagnosis and pre-scheduled opening of the turbine. The examined failures concern: (1) in-service rupture of the bell seal retainer nut between a SH steam inlet sleeve and the inner HP/IP cylinder, on turbines with a main steam inlet system with bell seals; (2) incorrect assembly of pressure seal rings between steam inlet sleeves and the inner cylinder on turbines with a main steam inlet system with pressure seal rings during a scheduled outage; (3) steam flow path restriction in IP turbine inlet; (4) steam flow path restriction in 1st HP turbine stage nozzles; and (5) steam flow path restriction in 2nd HP turbine stage vanes. Thermodynamic failure analysis and the subsequent analysis of turbine damage (mechanical and financial) enabled condition-based maintenance operations to be carried out.

Base-Load and Peak Electricity from a Combined Nuclear Heat and Fossil Combined-Cycle Plant  

SciTech Connect (OSTI)

A combined-cycle power plant is proposed that uses heat from a high-temperature reactor and fossil fuel to meet base-load and peak electrical demands. The high-temperature gas turbine produces shaft power to turn an electric generator. The hot exhaust is then fed to a heat recovery steam generator (HRSG) that provides steam to a steam turbine for added electrical power production. A simplified computational model of the thermal power conversion system was developed in order to parametrically investigate two different steady-state operation conditions: base load nuclear heat only from an Advanced High Temperature Reactor (AHTR), and combined nuclear heat with fossil heat to increase the turbine inlet temperature. These two cases bracket the expected range of power levels, where any intermediate power level can result during electrical load following. The computed results indicate that combined nuclear-fossil systems have the potential to offer both low-cost base-load electricity and lower-cost peak power relative to the existing combination of base-load nuclear plants and separate fossil-fired peak-electricity production units. In addition, electric grid stability, reduced greenhouse gases, and operational flexibility can also result with using the conventional technology presented here for the thermal power conversion system coupled with the AHTR.

Thermodynamics and Transport Phenomena in High Temperature Steam Electrolysis Cells  

SciTech Connect (OSTI)

Hydrogen can be produced from water splitting with relatively high efficiency using high temperature electrolysis. This technology makes use of solid-oxide cells, running in the electrolysis mode to produce hydrogen from steam, while consuming electricity and high temperature process heat. The overall thermal-to-hydrogen efficiency for high temperature electrolysis can be as high as 50%, which is about double the overall efficiency of conventional low-temperature electrolysis. Current large-scale hydrogen production is based almost exclusively on steam reforming of methane, a method that consumes a precious fossil fuel while emitting carbon dioxide to the atmosphere. An overview of high temperature electrolysis technology will be presented, including basic thermodynamics, experimental methods, heat and mass transfer phenomena, and computational fluid dynamics modeling.

In Japan, the main large capacity fossil-fuel power plant larger than 500 MW are supercritical units and the steam condition of 24.2 MPa, 538/566 C has been adopted. Through extensive development work, design and material technologies for steam turbines with a 593 C steam temperature have been established, and the steam condition of 24.2 MPa, 583/593 C was applied to the 700 MW steam turbine of Hekinan No.3 Unit, Chubu Electric Power Co., Inc. for the first time in Japan. This is also the world`s largest unit with a steam condition of 593 C. The Hekinan No. 3 Unit was designed and manufactured applying the latest technologies established for 593 C application. The unit was first rolled with steam in July 1992 and after successful trial operation and tests, the No. 3 Unit started commercial operation in April 1993. This paper introduces the latest technologies and the overhaul inspection results after about one year`s commercial operation.

GCFR steam generator conceptual design  

SciTech Connect (OSTI)

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.

Wet-steam erosion of steam turbine disks and shafts  

SciTech Connect (OSTI)

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 in the Ring Discharge  

Science Journals Connector (OSTI)

The behaviour of steam and its decomposition products in the ring discharge has been examined. Dry hydrogen is not dissociated. The production of atomic hydrogen is dependent upon the presence of steam which dissociates into hydroxyl and atomic hydrogen. A secondary source of atomic hydrogen is then afforded by the interaction of hydroxyl with molecular hydrogen. The escape from the discharge of atomic hydrogen, a long-lived species, favours the dissociation of steam. Mercury vapour, on the other hand, inhibits the formation of atomic hydrogen and thus leads to a high equilibrium steam concentration. Unlike dry hydrogen, dry oxygen is dissociated into atoms, but these have a short life as such and recombine in the discharge to form molecular oxygen and ozone. The reaction mechanisms occurring in the discharge are discussed in the light of spectrographic results.

Projection of world fossil fuels by country  

Science Journals Connector (OSTI)

Abstract Detailed projections of world fossil fuel production including unconventional sources were created by country and fuel type to estimate possible future fossil fuel production. Four critical countries (China, USA, Canada and Australia) were examined in detail with projections made on the state/province level. Ultimately Recoverable Resources (URR) for fossil fuels were estimated for three scenarios: Low = 48.4 ZJ, Best Guess (BG) = 75.7 ZJ, High = 121.5 ZJ. The scenarios were developed using Geologic Resources Supply-Demand Model (GeRS-DeMo). The Low and Best Guess (BG) scenarios suggest that world fossil fuel production may peak before 2025 and decline rapidly thereafter. The High scenario indicates that fossil fuels may have a strong growth till 2025 followed by a plateau lasting approximately 50 years before declining. All three scenarios suggest that world coal production may peak before 2025 due to peaking Chinese production and that only natural gas could have strong growth in the future. In addition, by converting the fossil fuel projections to greenhouse gas emissions, the projections were compared to IPCC scenarios which indicated that based on current estimates of URR there are insufficient fossil fuels to deliver the higher emission IPCC scenarios \\{A1Fl\\} and RCP8.5.

Monitoring of temperature-compensated conductivity in fossil power plants  

SciTech Connect (OSTI)

Specific conductivity is an inexpensive, reliable, on-line method for monitoring the overall level of contaminants and its trends in fossil plant cycles. The most important applications are the monitoring in makeup water and at the economizer inlet. In the makeup, the specific conductivity is related to the content of makeup ionic impurities and carbon dioxide. Specific conductivity at the economizer inlet is an indication of the ammonia level during normal operation, since other ionic impurity levels are relatively very low in relation to the ammonia content. Cation conductivity serves as an excellent diagnostic tool. The advantage of using strong-acid cation exchanger for the alkalizing agents elimination and for the great sensitivity improvement has already been recognized in the 1950`s. The cation conductivity is currently one of the most important {open_quotes}core parameters{close_quotes} in the Cycle Chemistry Improvement Project. In this project, the most important plant cycle locations where cation conductivity on-line monitoring is strongly advised are: condensate pump discharge; polisher outlet or economizer inlet; and hot reheat steam or main steam. An additional monitoring location is the blowdown or the downcomer of drum boilers. The cation conductivity monitoring at this location is becoming vital with the introduction of oxygenated chemistry and OH (sodium hydroxide) treatment in cycles with drum boilers. Degassed cation conductivity has been addressed. Applying this method, the effect of carbon dioxide on cation conductivity is eliminated by boiling off gaseous carbon dioxide before the actual cation conductivity monitoring. Therefore, the degassed cation conductivity reflects only the total non-volatile anionic impurity level.

Steam Pressure Reduction, Opportunities, and Issues  

SciTech Connect (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.

Catalytic steam reforming of hydrocarbons  

SciTech Connect (OSTI)

The hot effluent from the catalytic steam reforming of a major portion of a fluid hydrocarbon feed stream in the reformer tubes of a primary reformer, or said effluent after secondary reforming thereof, is mixed with the hot effluent from the catalytic steam reforming of the remaining portion of the feed discharged from the reformer tubes of a primary reformer-exchanger. The combined gas steam is passed on the shell side of the reformer-exchanger countercurrently to the passage of feed in the reformer tubes thereof, thus supplying the heat for the reforming of the portion of the feed passed through the reformer tubes of the reformerexchanger. At least about 2/3 of the hydrocarbon feed stream is passed to the reformer tubes of said primary reformer, heated by radiant heat transfer and/or by contact with combustion gases, at a steam/hydrocarbon mole ratio of about 2-4/1. The remainder of said feed stream is passed to the reformer tubes of said reformer -exchanger at a steam/hydrocarbon mole ratio of about 3-6/1. The reformer shell of the reformer-exchanger is internally insulated by a refractory lining or by use of a double shell with passage of water or a portion of the feed material between the inner and outer shells. There is no significant difference between the pressure inside and outside of the reformer tubes of said primary reformer-exchanger.

Solar-Augment Potential of U.S. Fossil-Fired Power Plants  

SciTech Connect (OSTI)

Concentrating Solar Power (CSP) systems utilize solar thermal energy for the generation of electric power. This attribute makes it relatively easy to integrate CSP systems with fossil-fired power plants. The 'solar-augment' of fossil power plants offers a lower cost and lower risk alternative to stand-alone solar plant construction. This study ranked the potential to add solar thermal energy to coal-fired and natural gas combined cycle (NGCC) plants found throughout 16 states in the southeast and southwest United States. Each generating unit was ranked in six categories to create an overall score ranging from Excellent to Not Considered. Separate analysis was performed for parabolic trough and power tower technologies due to the difference in the steam temperatures that each can generate. The study found a potential for over 11 GWe of parabolic trough and over 21 GWe of power tower capacity. Power towers offer more capacity and higher quality integration due to the greater steam temperatures that can be achieved. The best sites were in the sunny southwest, but all states had at least one site that ranked Good for augmentation.

Steam systems in industry: Energy use and energy efficiency improvement potentials  

SciTech Connect (OSTI)

Steam systems are a part of almost every major industrial process today. Thirty-seven percent of the fossil fuel burned in US industry is burned to produce steam. In this paper we will establish baseline energy consumption for steam systems. Based on a detailed analysis of boiler energy use we estimate current energy use in boilers in U.S. industry at 6.1 Quads (6.4 EJ), emitting almost 66 MtC in CO{sub 2} emissions. We will discuss fuels used and boiler size distribution. We also describe potential savings measures, and estimate the economic energy savings potential in U.S. industry (i.e. having payback period of 3 years or less). We estimate the nationwide economic potential, based on the evaluation of 16 individual measures in steam generation and distribution. The analysis excludes the efficient use of steam and increased heat recovery. Based on the analysis we estimate the economic potential at 18-20% of total boiler energy use, resulting in energy savings approximately 1120-1190 TBtu ( 1180-1260 PJ). This results in a reduction of CO{sub 2} emissions equivalent to 12-13 MtC.

Evaluation of steam path audits  

SciTech Connect (OSTI)

Tri-State Generation and Transmission association is the operating agent for the 1350 megawatt Craig Generating Station, located in northwestern Colorado. Tri-State has recently incorporated turbine steam path audits into their aggressive performance improvement program. The intent of the audits are to quantify and attain the most cost effective increase in turbine performance as a result of a major outage. Valuable information about performance losses in the turbine has been obtained from steam path audits conducted on the three Craig Units. However, accurate audit results often depend on the quality of measurements and the experience of the auditor. Without a second method to verify the results of a steam path audit, repairs might be performed on a non-cost effective basis, or significant performance degradations might be overlooked. In addition, an inaccurate audit may lead to erroneous expectations for performance improvements resulting from the maintenance performed during the outage.

FEMP-FTA--Steam Trap Performance Assessment  

Broader source: Energy.gov (indexed) [DOE]

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

Materials Performance in USC Steam  

SciTech Connect (OSTI)

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).

Recover heat from steam reforming  

SciTech Connect (OSTI)

Steam reforming is one of the most important chemical processes--it is used in the manufacture of ammonia, hydrogen, methanol, and many chemicals made from hydrogen and carbon monoxide. Furthermore, many current trends will increase its importance. For example, methanol for addition to gasoline is likely to be produced by steam reforming. Because steam reforming occurs at high temperatures--typically 750 C--900 C--it generates a large amount of waste heat. Clearly, heat recovery is crucial to process economics. A typical 50,000 Nm[sup 3]/h hydrogen plant using natural gas feed has a radiant heat duty of about 50 MW. At a radiant efficiency of 50% and fuel cost of $3/GJ, this means that the reformer fires $9 million worth of fuel per year. Obviously, this amount of fuel justifies a close loot at ways to reduce costs. This article first provides a brief overview of steam reforming. It then outlines the available heat-recovery options and explains how to select the best method.

Engineering assessment of condenser deaeration retrofits for cycling fossil plants: Final report  

SciTech Connect (OSTI)

High dissolved oxygen levels in the condensate feedwater system contribute significantly to corrosion problems in steam generators, turbine rotor and blading, feedwater piping, feedwater heaters, and other plant equipment. While ingress of oxygen and oxidizing species into the condensate feedwater system cannot be completely eliminated due to a large number of potential air inleakage paths including air in-leakage into the condensate in the hotwell section of the condenser, oxygen levels could be kept to a minimum even at partial and no-load operation by improved condensate deaeration. The corrosion problems encountered in PWR plants, as well as those causing increased maintenance requirements and plant deterioration in cycling fossil plants are growing concerns to utilities. These concerns have motivated EPRI to investigate the causes and to seek remedies for the high dissolved oxygen levels that occur at start-up, low operating loads and shutdown. The purpose of this project was to develop the design, install and test three independent systems that could serve to reduce and maintain the low, dissolved oxygen content in the condensate of a peaking fossil unit under all operating conditions. If the results of the tests are favorable, the devices could be used at other peaking fossil plants and nuclear plants. 5 refs., 28 figs., 7 tabs.

Europe Europe » Poland Poland Fossil-Fuel CO2 Emissions Graph graphic Graphics Data graphic Data Trends Carbon dioxide emissions from Poland's use of fossil-fuels and cement production climbed at a remarkably steady rate of 3.9% per year from 1800 until 1980, when they dropped abruptly (11.7%). Fossil-fuel CO2 emissions crept back up throughout the 1980s peaking in 1987 at 127 million metric tons of carbon. Since the 1987 high, CO2 emissions have plummeted 32% to early 1970s levels while per capita emissions have dropped to late 1960s levels. Poland is the world's ninth largest producer of coal and emissions are predominantly from coal burning: 97% in 1950 and 68% in 2008.

Development of knowledge bases for large steam turbine transients  

SciTech Connect (OSTI)

At this time, a number of high-qualified expert teams in different countries have accumulated significant experience in working up and introducing proficient algorithms of automated control, diagnostics, monitoring, on-line informative support, and off-line analysis for large steam turbines of fossil-fired and nuclear power plant units at their transients. In particular, such works were carried out at All-Russia Thermal Engineering Research Institute in Moscow. When put into effect, these developments do improve plant unit operation and maintenance. The creation of these algorithms is based on deep technological research of turbine transients with the use of their mathematical modeling. Currently, the central problem becomes a reiteration and adaptation of these developments to other objects which differ in design, scheme, and operation features. This problem is to be solved at the least cost. For certain complex tasks, it seems to be expedient to use expert system methodology with special knowledge bases. Along with the selection of such tasks, the creation of more or less general knowledge bases requires us to stratify the potential objects according to their principle features. The proposed forms of a knowledge presentation, including the mathematical models and logical rules, should correspond to the considered tasks and objects, as well as to the program tools to be applied. Such developments have been carried out for some tasks of the operating informative support and post-operating analysis of large steam turbine transients as well as their mathematical modeling.

Some problems of steam turbine lifetime assessment and extension  

SciTech Connect (OSTI)

The problems of lifetime assessment and extension in reference to power equipment (including high-temperature rotors and casings of power steam turbines) and theoretical and normative grounds for these procedures, as well as some specific measures to prolong the turbine service time and diagnose the turbine components` conditions in the operation process, were covered in many published works, including the authors` ones. The present paper is to consider in more details some aspects of these problems that have not been sufficiently considered in known publications. In particular, it seems important to dwell on experimental verification of some mathematical models for calculating temperatures, stresses, and strains in the turbine casings on the basis of direct measurements at turbines in service. Another item to be discussed ia an approach to choosing the system of interrelated criteria and safety factors referring to the upper admissible values of stresses, strains, cycles, and accumulated damage, as well as crack resistance, as applied to an adopted conception of the limiting states for the rotors and casings with taking into consideration their loads and resulted stress-strain states. In this connection, it is important to arrange and use properly the continuous monitoring of temperatures, stresses, and accumulated metal damage to assess the residual lifetime of the rotors and casings more accurately. Certain design, technology, and repair measures are briefly described. They have successfully been employed at fossil power plants of the former Soviet Union to raise the steam turbine reliability and durability.

Next Generation Engineered Materials for Ultra Supercritical Steam Turbines  

SciTech Connect (OSTI)

To reduce the effect of global warming on our climate, the levels of CO{sub 2} emissions should be reduced. One way to do this is to increase the efficiency of electricity production from fossil fuels. This will in turn reduce the amount of CO{sub 2} emissions for a given power output. Using US practice for efficiency calculations, then a move from a typical US plant running at 37% efficiency to a 760 C /38.5 MPa (1400 F/5580 psi) plant running at 48% efficiency would reduce CO2 emissions by 170kg/MW.hr or 25%. This report presents a literature review and roadmap for the materials development required to produce a 760 C (1400 F) / 38.5MPa (5580 psi) steam turbine without use of cooling steam to reduce the material temperature. The report reviews the materials solutions available for operation in components exposed to temperatures in the range of 600 to 760 C, i.e. above the current range of operating conditions for today's turbines. A roadmap of the timescale and approximate cost for carrying out the required development is also included. The nano-structured austenitic alloy CF8C+ was investigated during the program, and the mechanical behavior of this alloy is presented and discussed as an illustration of the potential benefits available from nano-control of the material structure.

Air–steam gasification of biomass in fluidized bed with CO2 absorption: A kinetic model for performance prediction  

Science Journals Connector (OSTI)

Abstract Significance of decarbonized energy production in the context of a foreseeable hydrogen economy has called for the need of extensive research in biomass gasification-carbon dioxide capture technique. The feasibility of calcium oxide as a sorbent for CO2 in syngas is studied for air–steam fluidized bed (FB) gasification through a reaction kinetic modeling approach. Arrhenius rate equations are employed for primary and secondary pyrolysis, gasification and carbonation reactions. Devolatilization product yields are predicted using available correlations for FB gasification and cracking of tar is incorporated. Parametric performance analysis is carried out highlighting the significance of equivalence ratio (ER), gasification temperature, steam to biomass ratio (SBR) and sorbent to biomass ratio (SOBR). The effects of various gasifying media on H2 concentration and performance indicators such as heating value and efficiencies are analyzed. The simulation results are validated with the reported experimental results. The kinetic study reveals that air–steam gasification significantly reduces the unreacted steam but at a lower H2 concentration than steam gasification. A maximum of 53% hydrogen rich gas mixture is predicted at ER = 0.25, SBR = 1.5, SOBR = 2.7 and 1000 K. Against fossil fuel expended steam gasification, pure oxygen gasification is suggested by the study.

Numerical study of primary steam superheating effects on steam ejector flow and its pumping performance  

Science Journals Connector (OSTI)

Abstract The effects of primary steam superheating on steam condensation in nozzle and the performance of steam ejector were investigated using CFD (computational fluid dynamics) method. Using a wet steam model being proposed in our previous study, simulations based on the primary steam with five superheated levels were performed, and the results demonstrate the superheating operation of the primary steam weakens the spontaneous condensation intensity and postpones its occurrence within the nozzle vicinity. Due to the droplets nucleation refinement for the condensation of superheated steam, the mixing process between the primary and the secondary fluids is improved. Consequently, a higher entrainment ratio is achieved. However, the superheating operation may not exceed 20 K, as its contribution on entrainment ratio improvement is not as significant as 0 K–20 K superheating, and too much superheating will requires more energy as input, which is not a practical solution to further improve the steam ejector pumping performance.

Efficiently generate steam from cogeneration plants  

SciTech Connect (OSTI)

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

Fossil Biodiversity: Red Noise Plus Signal  

E-Print Network [OSTI]

We have examined the Fourier power spectrum as well as the Hurst exponent of extinction, origination, and total biodiversity in the marine fossil record, using a recently improved geologic timescale. We find all of them strongly inconsistent with past claims of self-similarity as well as inconsistent with random walk behavior. Instead, they are dominated by low-frequency power, with approximate f^-2 power over one decade in frequency. The spectrum turns over at about 10^8 y, lending plausibility to connections with galactic dynamics. Even in the background of this low-frequency dominance, a previously noted 62 My biodiversity cycle stands out with better than 99% confidence above the noise level, accounting for about 35% of the total variance in the fossil biodiversity record.

Acoustic monitoring and signature analysis in nuclear and fossil energy generation  

Science Journals Connector (OSTI)

Acoustic monitoring and analysis in nuclear and fossil energy plants has been accompanied by transducer development for the hot environment. The Nuclear Regulatory Commission requires acoustic monitoring systems on nuclear reactors for detecting potential failures. Accelerometers are attached at critical points and their output is automatically analyzed to give warnings of loose parts or excessive vibration. In addition to providing a warning the system can monitor arrival time to be used for fault location. For use as a potential boiling detector of breeder reactors the acoustic signature of the sodium coolant boiling has been compared with background noise level. High temperature sodium?immersible microphones and waveguides for smooth energy transfer were developed for this investigation. High?temperature acoustic sensors have been used in a coal gasification plant. The presence of solids in a steam?char line has been automatically determined using passive monitoring of relative sound intensities of different frequency bands.

Designing an ultrasupercritical steam turbine  

SciTech Connect (OSTI)

Carbon emissions produced by the combustion of coal may be collected and stored in the future, but a better approach is to reduce the carbon produced through efficient combustion technologies. Increasing the efficiency of new plants using ultrasupercritical (USC) technology will net less carbon released per megawatt-hour using the world's abundant coal reserves while producing electricity at the lowest possible cost. The article shows how increasing the steam turbine operating conditions for a new USC project in the USA and quantify the potential CO{sub 2} reduction this advanced design makes possible. 7 figs., 3 tabs.

Steam turbine materials and corrosion  

SciTech Connect (OSTI)

Ultra supercritical (USC) power plants offer the promise of higher efficiencies and lower emissions. Current goals of the U.S. Department of Energy’s Advanced Power Systems Initiatives include coal generation at 60% efficiency, which would require steam temperatures of up to 760°C. This research examines the steamside oxidation of alloys for use in USC systems, with emphasis placed on applications in high- and intermediate-pressure turbines. The list of alloys being examined is discussed, including the addition of new alloys to the study. These include alloy 625, selected because of its use as one of the two alloys used for turbine rotors, valves, casings, blading and bolts in the European AD700 full-scale demonstration plant (Scholven Unit F). The other alloy, alloy 617, is already one of the alloys currently being examined by this project. Other new alloys to the study are the three round robin alloys in the UK-US collaboration: alloys 740, TP347HFG, and T92. Progress on the project is presented on cyclic oxidation in 50% air – 50% water vapor, furnace exposures in moist air, and thermogravimetric analysis in argon with oxygen saturated steam. An update on the progress towards obtaining an apparatus for high pressure exposures is given.

Steam Turbine Control Valve Noise  

Science Journals Connector (OSTI)

Although noise problems with steam turbine control valves have existed before they have become more prominent with nuclear turbines whose valves range to 20 in. in diameter. Our first?generation nuclear control valves were unacceptably noisy when operating under chocked conditions. These noise levels have been ameliorated by incorporation of a valve cage with numerous small holes. Rational design rules for this “dispersive muffler” have been developed from published multiple?jet noise data and improved through our own tests. However we are also evaluating other low?noise valve configurations which are consistent with turbine requirements. The approach we are developing is to investigate the internal aerodynamic noisegeneration in small air model tests and to combine this with measurements of pipe?wall transmission characteristics (being reported separately) to predict externally radiated noise. These predictions will be checked in a new steam test facility for complete scale?model valves. The small air tests show that acoustic efficiencies of throttling valve flows tend to vary with third power of Mach number when exhausting into space and with a lesser power when enclosed in a downstream pipe. At some pressure ratios narrow?band spikes appear in the spectrum and for some configurations step changes in sound power are associated with transitions in flow regimes.

Experimental study on steam plume and temperature distribution for sonic steam jet  

Science Journals Connector (OSTI)

The sonic steam jet in subcooled water was investigated experimentally over a wide range of steam mass flux and water temperature conditions. Four different steam plume shapes were observed in present test conditions, and the condensation form was mainly controlled by the steam mass flux and water temperature. Moreover, the unstable jet was observed on the condition of low steam mass flux and high water temperature. The transition criterion of unstable-stable jet was also given. The temperature fields in the steam plume and in the surrounding water were measured. Axial temperature distributions represented the four typical steam plumes, and the fluctuation of axial temperature confirmed the existence of expansion and compression waves. Additionally, the radial temperature distributions were independent of water temperature for small radial distance at nozzle exit, and further the axial location was apart from the nozzle exit, longer the radial distance affected by the momentum diffusion.

Performance Assessment of Flashed Steam Geothermal Power Plant  

SciTech Connect (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.

Steam turbine upgrades: A utility based approach  

SciTech Connect (OSTI)

In the increasingly competitive power generation markets utilities must strive towards lower electricity generation costs, whilst relying on an aging steam turbine fleet. By the year 2000 more than 25% of the global steam turbine capacity will be older than 30 years. The heat rate of such units is generally considerably higher than that of equivalent new plant, and such equipment can be further disadvantaged by increased maintenance costs and forced outage rates. Over the past decade steam turbine conversion, modification, and upgrade packages have become an increasingly important part of the European steam turbine market. Furthermore, many utilities now realize that enhanced cost-effectiveness can often be obtained by moving away from the original equipment manufacturer (OEM), and the upgrading of other manufacturers' plant is now routine within the steam turbine industry. By working closely with customers, GE has developed a comprehensive range of steam turbine upgrade packages, including advanced design steampaths which can increase the performance of existing turbine installations to levels comparable with new plant. Such packages are tailor-made to the requirements of each customer, to ensure that the most cost-effective engineering solution is identified. This paper presents an overview of GE's state-of-the-art steam turbine technology, and continues to describe typical economic models for turbine upgrades.

High activity steam reforming iron oxide catalysts are described. Such catalysts can be unsupported utilizing at least 90% by weight iron oxide and various modifiers (Ai/sub 2/O/sub 3/, K/sub 2/O, CaO, SiO/sub 2/) or unmodified and supported on such things as alumina, CaO impregnated alumina, and lanthanum stabilized alumina. When used in steam reformers such as autothermal and tubular steam reformers, these catalysts demonstrate much improved resistance to carbon plugging.

Direct-Steam Linear Fresnel Performance Model for NREL's System Advisor Model  

SciTech Connect (OSTI)

This paper presents the technical formulation and demonstrated model performance results of a new direct-steam-generation (DSG) model in NREL's System Advisor Model (SAM). The model predicts the annual electricity production of a wide range of system configurations within the DSG Linear Fresnel technology by modeling hourly performance of the plant in detail. The quasi-steady-state formulation allows users to investigate energy and mass flows, operating temperatures, and pressure drops for geometries and solar field configurations of interest. The model includes tools for heat loss calculation using either empirical polynomial heat loss curves as a function of steam temperature, ambient temperature, and wind velocity, or a detailed evacuated tube receiver heat loss model. Thermal losses are evaluated using a computationally efficient nodal approach, where the solar field and headers are discretized into multiple nodes where heat losses, thermal inertia, steam conditions (including pressure, temperature, enthalpy, etc.) are individually evaluated during each time step of the simulation. This paper discusses the mathematical formulation for the solar field model and describes how the solar field is integrated with the other subsystem models, including the power cycle and optional auxiliary fossil system. Model results are also presented to demonstrate plant behavior in the various operating modes.

Chapter 13 - Energy Conversion of Biomass and Recycling of Waste Plastics Using Supercritical Fluid, Subcritical Fluid and High-Pressure Superheated Steam  

Science Journals Connector (OSTI)

Abstract Utilization of unused or waste biomass as fuels is receiving much attention owing to the reduction of CO2 emission and the development of alternative energy to expensive fossil fuels. On the other hand, the recycling of waste plastics is important for the prevention of the exhaustion of fossil resources. In this chapter, typical several examples of the energy conversion of biomass and the recycling of waste plastics using supercritical fluid, subcritical fluid, and high-pressure superheated steam were introduced: (1) bioethanol production from paper sludge with subcritical water, (2) hydrogen production from various biomass with high-pressure superheated steam, (3) production of composite solid fuel from waste biomass and plastics with subcritical water, (4) waste treatment and recovery of thermal energy with high-pressure superheated steam oxidation, (5) recycling of carbon fiber-reinforced plastic with high-pressure superheated steam and supercritical alcohol, (6) recycling of laminate film with subcritical water, and (7) recycling of cross-linked polyethylene with supercritical methanol.

Apparatus and methods of reheating gas turbine cooling steam and high pressure steam turbine exhaust in a combined cycle power generating system  

DOE Patents [OSTI]

In a combined cycle system having a multi-pressure heat recovery steam generator, a gas turbine and steam turbine, steam for cooling gas turbine components is supplied from the intermediate pressure section of the heat recovery steam generator supplemented by a portion of the steam exhausting from the HP section of the steam turbine, steam from the gas turbine cooling cycle and the exhaust from the HP section of the steam turbine are combined for flow through a reheat section of the HRSG. The reheated steam is supplied to the IP section inlet of the steam turbine. Thus, where gas turbine cooling steam temperature is lower than optimum, a net improvement in performance is achieved by flowing the cooling steam exhausting from the gas turbine and the exhaust steam from the high pressure section of the steam turbine in series through the reheater of the HRSG for applying steam at optimum temperature to the IP section of the steam turbine.

Combating global warming via non-fossil fuel energy options  

Science Journals Connector (OSTI)

Non-fossil fuel energy options can help reduce or eliminate the emissions of greenhouse gases and are needed to combat climate change. Three distinct ways in which non-fossil fuel options can be used in society are examined here: the capture/production of non-fossil fuel energy sources, their conversion into appropriate energy carriers and increased efficiency throughout the life cycle. Non-fossil fuel energy sources are insufficient to avoid global warming in that they are not necessarily readily utilisable in their natural forms. Hydrogen energy systems are needed to facilitate the use of non-fossil fuels by converting them to two main classes of energy carriers: hydrogen (and hydrogen-derived fuels) and electricity. High efficiency is needed to allow the greatest benefits to be attained from energy options in terms of climate change and other factors. A case study is considered involving the production of hydrogen from non-fossil energy sources via thermochemical water decomposition. Thermochemical water decomposition provides a realistic future non-fossil fuel energy option, which can be driven by non-fossil energy sources (particularly nuclear or solar energy) and help combat global warming.

Solving chemical and mechanical problems of PWR steam generators  

SciTech Connect (OSTI)

Steam generators in power plants, based on pressurized water reactors (PWRs), transfer heat from a primary coolant system (pressurized water) to a secondary coolant system. Primary coolant water is heated in the core and passes through the steam generator that transfers heat to the secondary coolant water to make steam. The steam then drives a turbine that turns an electric generator. Steam is condensed and returned to the steam generator as feedwater. Two types of PWR steam generators are in use: recirculating steam generators (RSGs) and once-through steam generators (OTSGs). Since most of the units are vertical, only vertical units are discussed in this article. Some vertical units have operated with a minimum of problems, while others have experienced a variety of corrosion and mechanically-induced problems that have caused unscheduled outages and expensive repairs.

Evaluation of hybrid solar/fossil Rankine-cooling concept  

SciTech Connect (OSTI)

The hybrid solar/fossil Rankine cycle is analyzed thermodynamically to determine fuel use and efficiency. The hybrid system is briefly compared with solar organic Rankine systems with a fossil fuel auxiliary mode, and with geothermal resources. The economic evaluation compares the present value of the superheater fuel cost over the system lifetime with the first cost reduction obtained by substituting a hybrid solar/fossil Rankine engine for an organic Rankine engine. The economics analysis indicates that even if the hybrid solar/fossil Rankine cooling system were developed to the point of being a commercial product with an economic advantage over an otherwise equivalent solar organic Rankine cooling system, it would gradually lose that advantage with rising fuel costs and decreasing collector costs. From the standpoint of national fossil fuel conservation, the hybrid concept would be preferable only in applications where the operating duration in the solar/fossil mode would be substantially greater than in the fossil fuel-only auxiliary mode.

Simulation of Steam Reformers for Methane  

Science Journals Connector (OSTI)

Abstract A model is developed for industrial steam reformers for both top fired and side fired furnaces. The catalyst tube model is a one-dimensional heterogeneous model with intra-particle diffusional resistances. The two point boundary value differential equations of the catalyst pellets are solved using a modified novel orthogonal collocation technique to obtain the effectiveness factor variation along the length of the reactor. The side fired furnace equations are algebraic equations, the top fired furnace equations are two-point boundary value differential equations which are solved using the orthogonal collocation technique. A recently developed more general rate expression is used. The model performance is checked against industrial steam reformers. The model is used to investigate the effect of various parameters on the behaviour of the catalyst tubes and the furnace. The effectiveness factor variation along the length of the catalyst tube is also analysed. Keywords: Steam Reforming, Reactor modeling, Digital Simulation, effectiveness factor

Ultra supercritical turbines--steam oxidation  

SciTech Connect (OSTI)

Ultra supercritical (USC) power plants offer the promise of higher efficiencies and lower emissions, which are goals of the U.S. Department of Energy?s Advanced Power Systems Initiatives. Most current coal power plants in the U.S. operate at a maximum steam temperature of 538?C. However, new supercritical plants worldwide are being brought into service with steam temperatures of up to 620?C. Current Advanced Power Systems goals include coal generation at 60% efficiency, which would require steam temperatures of up to 760?C. This research examines the steamside oxidation of advanced alloys for use in USC systems, with emphasis placed on alloys for high- and intermediate-pressure turbine sections. Initial results of this research are presented.

At a pressure of 220 atm and a temperature of 374?°C there is a second-order phase transition between water and steam. Understanding it requires a key concept of both condensed matter and elementary particle physics: the renormalization group. Its basic ideas are explained with images from computer simulations of the lattice gas model. Then I briefly review how the renormalization group is used to compute critical coefficients for the water–steam phase transition. The results of this calculation are in good agreement with experiment. Finally some applications in particle physics and string theory are mentioned.

Status of fossil energy resources: A global perspective  

SciTech Connect (OSTI)

This article deals with recently status of global fossil energy sources. Fossil energy sources have been split into three categories: oil,coal, and natural gas. Fossil fuels are highly efficient and cheap. Currently oil is the fastest primary energy source in the world (39% of world energy consumption). Coal will be a major source of energy for the world for the foreseeable future (24% of world energy consumption). In 2030, coal covers 45% of world energy needs. Natural gas is expected to be the fastest growing component of world energy consumption (23% of world energy consumption). Fossil fuel extraction and conversion to usable energy has several environmental impacts. They could be a major contributor to global warming and greenhouse gases and a cause of acid rain; therefore, expensive air pollution controls are required.

Carbon deposition in steam reforming and methanation  

SciTech Connect (OSTI)

The purpose of this review is to survey recent studies of carbon deposition on metals used as catalysts in steam reforming and methanation, emphasizing research where significant progress has been made. Where possible, an attempt is made to treat the fundamental nature of carbon formation and deactivation by carbon and the relationships between these two phenomena. Steam reforming and methanation are emphasized in this review because (1) deactivation of catalysts by carbon deposits is a serious concern in both processes, (2) much of the previous research with carbon formation on metals involved one or the other of these two reactions, and (3) there are interesting differences and similarities between these two reactions; for example, methanation is typically carried out at moderate reaction temperatures (200-450/sup 0/C) while steam reforming is typically carried out at significantly higher reaction temperatures (600-900/sup 0/C). Yet the two reactions are very closely related, since methane steam reforming is the reverse of methanation of CO. Moreover, there is evidence that some of the carbons formed in these two different processes are similar in their morphology.

Natural gas-assisted steam electrolyzer  

DOE Patents [OSTI]

An efficient method of producing hydrogen by high temperature steam electrolysis that will lower the electricity consumption to an estimated 65 percent lower than has been achievable with previous steam electrolyzer systems. This is accomplished with a natural gas-assisted steam electrolyzer, which significantly reduces the electricity consumption. Since this natural gas-assisted steam electrolyzer replaces one unit of electrical energy by one unit of energy content in natural gas at one-quarter the cost, the hydrogen production cost will be significantly reduced. Also, it is possible to vary the ratio between the electricity and the natural gas supplied to the system in response to fluctuations in relative prices for these two energy sources. In one approach an appropriate catalyst on the anode side of the electrolyzer will promote the partial oxidation of natural gas to CO and hydrogen, called Syn-Gas, and the CO can also be shifted to CO.sub.2 to give additional hydrogen. In another approach the natural gas is used in the anode side of the electrolyzer to burn out the oxygen resulting from electrolysis, thus reducing or eliminating the potential difference across the electrolyzer membrane.

A parametric study of steam injected gas turbine with steam injector  

SciTech Connect (OSTI)

The interest in the STIG concept has arisen from the fact that the application shows high flexibility in power output, and therefore can serve well as a peak load unit. A new addition to the STIG-cycle is proposed and investigated in this paper. The introduction of steam injectors at the injection point of the steam is proposed to lightly raise the pressure of the gas flow entering the expander. The injector reduces the thermodynamic irreversibilities associated with the throttling nature of injecting a high pressure steam into a lower pressure region. A thermodynamic study has been conducted on the STIG with steam injectors for power generation. Steam pressure and superheating temperature are the main parameters for the system. The impact and usefulness of supplementary firing before the HRSG has also been investigated. The results are compared with a STIG with throttling valves instead of injectors. The efficiency and power output proves to increase somewhat upon introducing the steam injectors. This modification can be of commercial interest since the injectors are of low installation cost and need virtually no maintenance.

Steam turbine maintenance and repair technology: Reducing planned-outage costs  

SciTech Connect (OSTI)

The North American Electric Reliability Council (NAERC) reported that the average loss of equivalent availability per outage for a major fossil turbine overhaul is 323,000 MW-HR. The Electric Power Research Institute (EPRI) Generation and Storage Division, is in the first phase of a major research project to reduce the duration and/or frequency of steam turbine maintenance outages. This project consists of an assessment of the current state-of-the-art turbine maintenance and repair techniques and technologies. It is based on a review of current turbine maintenance practices of the US, European, Japanese, and Australian utility industries. Emphasized are maintenance and repair activities that have the most significant impact on outage duration or frequency. Twenty-six key turbine maintenance activities and the current best techniques were identified for use by utility maintenance personnel. Overall outage durations could be reduced if the duration of these activities were shortened or if they were performed more effectively. Recommended projects for development of advanced steam turbine maintenance technology were identified. 29 refs., 46 figs., 9 tabs.

Thermodynamic investigation and environment impact assessment of hydrogen production from steam reforming of poultry tallow  

Science Journals Connector (OSTI)

Abstract In this research, various assessment tools are applied to comprehensively investigate hydrogen production from steam reforming of poultry tallow (PT). These tools investigate the chemical reactions, design and simulate the entire hydrogen production process, study the energetic performance and perform an environment impact assessment using life cycle assessment (LCA) methodology. The chemical reaction investigation identifies thermodynamically optimal operating conditions at which PT may be converted to hydrogen via the steam reforming process. The synthesis gas composition was determined by simulations to minimize the Gibbs free energy using the Aspen Plus™ 10.2 software. These optimal conditions are, subsequently, used in the design and simulation of the entire PT-to-hydrogen process. LCA is applied to evaluate the environmental impacts of PT-to-hydrogen system. The system boundaries include rendering and reforming along with the required transportation process. The reforming inventories data are derived from process simulation in Aspen Plus™, whereas the rendering data are adapted from a literature review. The life cycle inventories data of PT-to-hydrogen are computationally implemented into SimaPro 7.3. A set of seven relevant environmental impact categories are evaluated: global warming, abiotic depletion, acidification, eutrophication, ozone layer depletion, photochemical oxidant formation, and cumulative non-renewable fossil and nuclear energy demand. The results are subject to a systematic sensitivity analysis and compared to those calculated for hydrogen production from conventional steam methane reforming. The LCA results indicate that the thermal energy production process is the main contributor to the selected environmental impact categories. Improvement actions to minimize the reforming thermal energy and the transport distance are strongly recommended as they would lead to relevant environmental improvements.

Thermochemically recuperated and steam cooled gas turbine system  

DOE Patents [OSTI]

A gas turbine system in which the expanded gas from the turbine section is used to generate the steam in a heat recovery steam generator and to heat a mixture of gaseous hydrocarbon fuel and the steam in a reformer. The reformer converts the hydrocarbon gas to hydrogen and carbon monoxide for combustion in a combustor. A portion of the steam from the heat recovery steam generator is used to cool components, such as the stationary vanes, in the turbine section, thereby superheating the steam. The superheated steam is mixed into the hydrocarbon gas upstream of the reformer, thereby eliminating the need to raise the temperature of the expanded gas discharged from the turbine section in order to achieve effective conversion of the hydrocarbon gas.

A three-dimensional laboratory steam injection model allowing in situ saturation measurements. [Comparing steam injection and steam foam injection with nitrogen and without nitrogen  

SciTech Connect (OSTI)

The CT imaging technique together with temperature and pressure measurements were used to follow the steam propagation during steam and steam foam injection experiments in a three dimensional laboratory steam injection model. The advantages and disadvantages of different geometries were examined to find out which could best represent radial and gravity override flows and also fit the dimensions of the scanning field of the CT scanner. During experiments, steam was injected continuously at a constant rate into the water saturated model and CT scans were taken at six different cross sections of the model. Pressure and temperature data were collected with time at three different levels in the model. During steam injection experiments, the saturations obtained by CT matched well with the temperature data. That is, the steam override as observed by temperature data was also clearly seen on the CT pictures. During the runs where foam was present, the saturation distributions obtained from CT pictures showed a piston like displacement. However, the temperature distributions were different depending on the type of steam foam process used. The results clearly show that the pressure/temperature data alone are not sufficient to study steam foam in the presence of non-condensible gas.

Large steam turbine repair: A survey  

SciTech Connect (OSTI)

This report covers a survey taken to document the current state-of-the-art in repairs to large steam turbines. One objective was to provide information to assist utilities in making repair or replacement decisions. The survey revealed that a large number of repairs have been successfully repaired involving both mechanical and welding repair techniques. Repair techniques have been improving in recent years and are being used more frequently. No guidelines or codes exist for the repair of steam turbine components so each repair is primarily controlled by agreement between the utility, contractor and insurer. Types of repairs are reviewed in this report and in addition, the capabilities of various contractors who are currently active in providing repair service. 40 refs., 10 figs., 4 tabs.

Simulation of steam reformers for methane  

Science Journals Connector (OSTI)

A model is developed for industrial steam reformers for both top fired and side fired furnaces. The catalyst tube model is a one-dimensional heterogeneous model with intra-particle diffusional resistances. The two point boundary value differential equations of the catalyst pellets are solved using a modified novel orthogonal collocation technique to obtain the effectiveness factor variation along the length of the reactor. The side fired furnace equations are algebraic equations, the top fired furnace equations are two-point boundary value differential equations which are solved using the orthogonal collocation technique. A recently developed more general rate expression is used. The model performance is checked against industrial steam reformers. The model is used to investigate the effect of various parameters on the behaviour of the catalyst tubes and the furnace. The effectiveness factor variation along the length of the catalyst tube is also analysed.

Effect of steam on supported metal catalysts  

SciTech Connect (OSTI)

In order to examine the effect of steam on supported metal catalysts, model supported metal catalysts of Ni, Co, or Fe on alumina have been heated in steam at 700/sup 0/C. The transmission electron micrographs show that for all these metals, patches of film extend from the crystallites. Prolonged heating results in the disappearance of the patches which probably spread as a contiguous film over the entire surface of the substrate. The degree of spreading is in the order: C0 > Ni > Fe. On subsequent heating in H/sub 2/, small crystallites were generated, probably via the rupture of the contiguous film. The contraction of the patches of film bridging two or several particles caused the coalescence of the latter. This subsequent heating in H/sub 2/ favors redispersion only when the heating time is sufficiently short. Prolonged heating in H/sub 2/ leads to the disappearance of the small particles.

Laser removal of sludge from steam generators  

DOE Patents [OSTI]

A method of removing unwanted chemical deposits known as sludge from the metal surfaces of steam generators with laser energy is provided. Laser energy of a certain power density, of a critical wavelength and frequency, is intermittently focused on the sludge deposits to vaporize them so that the surfaces are cleaned without affecting the metal surface (sludge substrate). Fiberoptic tubes are utilized for laser beam transmission and beam direction. Fiberoptics are also utilized to monitor laser operation and sludge removal.

Materials Performance in USC Steam Portland  

SciTech Connect (OSTI)

Goals of the U.S. Department of Energy's Advanced Power Systems Initiatives include power generation from coal at 60% efficiency, which requires steam conditions of up to 760 C and 340 atm, co-called advanced ultrasupercritical (A-USC) steam conditions. A limitation to achieving the goal is a lack of cost-effective metallic materials that can perform at these temperatures and pressures. Some of the more important performance limitations are high-temperature creep strength, fire-side corrosion resistance, and steam-side oxidation resistance. Nickel-base superalloys are expected to be the materials best suited for steam boiler and turbine applications above about 675 C. Specific alloys of interest include Haynes 230 and 282, Inconel 617, 625 and 740, and Nimonic 263. Further validation of a previously developed chromia evaporation model is shown by examining the reactive evaporation effects resulting from exposure of Haynes 230 and Haynes 282 to moist air environments as a function of flow rate and water content. These two alloys differ in Ti and Mn contents, which may form outer layers of TiO{sub 2} or Cr-Mn spinels. This would in theory decrease the evaporation of Cr{sub 2}O{sub 3} from the scale by decreasing the activity of chromia at the scale surface, and be somewhat self-correcting as chromia evaporation concentrates the Ti and Mn phases. The apparent approximate chromia activity was found for each condition and alloy that showed chromia evaporation kinetics. As expected, it was found that increasing the gas flow rate led to increased chromia evaporation and decreased chromia activity. However, increasing the water content in moist air increased the evaporation, but results were mixed with its effect on chromia activity.

Underground coal gasification using oxygen and steam  

SciTech Connect (OSTI)

In this paper, through model experiment of the underground coal gasification, the effects of pure oxygen gasification, oxygen-steam gasification, and moving-point gasification methods on the underground gasification process and gas quality were studied. Experiments showed that H{sub 2} and CO volume fraction in product gas during the pure oxygen gasification was 23.63-30.24% and 35.22-46.32%, respectively, with the gas heating value exceeding 11.00 MJ/m{sup 3}; under the oxygen-steam gasification, when the steam/oxygen ratio stood at 2: 1, gas compositions remained virtually stable and CO + H{sub 2} was basically between 61.66 and 71.29%. Moving-point gasification could effectively improve the changes in the cavity in the coal seams or the effects of roof inbreak on gas quality; the ratio of gas flowing quantity to oxygen supplying quantity was between 3.1:1 and 3.5:1 and took on the linear changes; on the basis of the test data, the reasons for gas quality changes under different gasification conditions were analyzed.

Measuring non-condensable gases in steam  

SciTech Connect (OSTI)

In surgery, medical devices that are used should be sterilized. To obtain surface steam sterilization conditions, not only in the sterilizer chamber itself but also in the loads to be sterilized, the amount of non-condensable gases (NCGs), for instance air, should be very low. Even rather small fractions of NCGs (below 1 %) seriously hamper steam penetration in porous materials or devices with hollow channels (e.g., endoscopes). A recently developed instrument which might detect the presence of residual NCGs in a reliable and reproducible way is the 3M{sup TM} Electronic Test System (ETS). In this paper, a physical model is presented that describes the behavior of this instrument. This model has been validated by experiments in which known fractions of NCGs were introduced in a sterilizer chamber in which an ETS was placed. Despite several approximations made in the model, a good agreement is found between the model predictions and the experimental results. The basic principle of the ETS, measuring the heat transfer by condensation on a cooled surface, permits a very sensitive detection of NCGs in harsh environments like water vapor at high temperatures and pressures. Our model may serve to develop adapted and optimized versions of this instrument for use outside the field of sterilization, e.g., in heat exchangers based on steam condensation.

Causal relationship between fossil fuel consumption and economic growth in the world  

Science Journals Connector (OSTI)

Fossil fuels are major sources of energy, and have several advantages over other primary energy sources. Without extensive dependence on fossil fuels, it is questionable whether our economic prosperity can continue. This paper analyses cointegration and causality between fossil fuel consumption and economic growth in the world over the period 1971 to 2008. The estimation results indicate that fossil fuel consumption and GDP are cointegrated and there exists long-run unidirectional causality from fossil fuel consumption to GDP. This paper also investigates the nexus between non-fossil energy consumption and GDP, and shows that there is no causality between the variables. The conclusions are that reducing fossil fuel consumption may hamper economic growth, and that it is unlikely that non-fossil energy will substantially replace fossil fuels. This paper also examines causal linkages between the variables using a trivariate model, and obtains the same results as those from the bivariate model.

Hydrogen-or-Fossil-Combustion Nuclear Combined-Cycle Systems for Base- and Peak-Load Electricity Production  

SciTech Connect (OSTI)

A combined-cycle power plant is described that uses (1) heat from a high-temperature nuclear reactor to meet base-load electrical demands and (2) heat from the same high-temperature reactor and burning natural gas, jet fuel, or hydrogen to meet peak-load electrical demands. For base-load electricity production, fresh air is compressed; then flows through a heat exchanger, where it is heated to between 700 and 900 C by heat provided by a high-temperature nuclear reactor via an intermediate heat-transport loop; and finally exits through a high-temperature gas turbine to produce electricity. The hot exhaust from the Brayton-cycle gas turbine is then fed to a heat recovery steam generator that provides steam to a steam turbine for added electrical power production. To meet peak electricity demand, the air is first compressed and then heated with the heat from a high-temperature reactor. Natural gas, jet fuel, or hydrogen is then injected into the hot air in a combustion chamber, combusts, and heats the air to 1300 C-the operating conditions for a standard natural-gas-fired combined-cycle plant. The hot gas then flows through a gas turbine and a heat recovery steam generator before being sent to the exhaust stack. The higher temperatures increase the plant efficiency and power output. If hydrogen is used, it can be produced at night using energy from the nuclear reactor and stored until needed. With hydrogen serving as the auxiliary fuel for peak power production, the electricity output to the electric grid can vary from zero (i.e., when hydrogen is being produced) to the maximum peak power while the nuclear reactor operates at constant load. Because nuclear heat raises air temperatures above the auto-ignition temperatures of the various fuels and powers the air compressor, the power output can be varied rapidly (compared with the capabilities of fossil-fired turbines) to meet spinning reserve requirements and stabilize the electric grid. This combined cycle uses the unique characteristics of high-temperature reactors (T>700 C) to produce electricity for premium electric markets whose demands can not be met by other types of nuclear reactors. It may also make the use of nuclear reactors economically feasible in smaller electrical grids, such as those found in many developing countries. The ability to rapidly vary power output can be used to stabilize electric grid performance-a particularly important need in small electrical grids.

Comments on US LMFBR steam generator base technology  

SciTech Connect (OSTI)

The development of steam generators for the LMFBR was recognized from the onset by the AEC, now DOE, as a difficult, challenging, and high-priority task. The highly reactive nature of sodium with water/steam requires that the sodium-water/steam boundaries of LMFBR steam generators possess a degree of leak-tightness reliability not normally attempted on a commercial scale. In addition, the LMFBR steam generator is subjected to high fluid temperatures and severe thermal transients. These requirements place great demand on materials, fabrication processes, and inspection methods; and even greater demands on the designer to provide steam generators that can meet these demanding requirements, be fabricated without unreasonable shop requirements, and tolerate off-normal effects.

High Efficiency Direct Carbon and Hydrogen Fuel Cells for Fossil Fuel Power Generation  

SciTech Connect (OSTI)

Hydrogen he1 cells have been under development for a number of years and are now nearing commercial applications. Direct carbon fuel cells, heretofore, have not reached practical stages of development because of problems in fuel reactivity and cell configuration. The carbon/air fuel cell reaction (C + O{sub 2} = CO{sub 2}) has the advantage of having a nearly zero entropy change. This allows a theoretical efficiency of 100 % at 700-800 C. The activities of the C fuel and CO{sub 2} product do not change during consumption of the fuel. Consequently, the EMF is invariant; this raises the possibility of 100% fuel utilization in a single pass. (In contrast, the high-temperature hydrogen fuel cell has a theoretical efficiency of and changes in fuel activity limit practical utilizations to 75-85%.) A direct carbon fuel cell is currently being developed that utilizes reactive carbon particulates wetted by a molten carbonate electrolyte. Pure COZ is evolved at the anode and oxygen from air is consumed at the cathode. Electrochemical data is reported here for the carbon/air cell utilizing carbons derived from he1 oil pyrolysis, purified coal, purified bio-char and petroleum coke. At 800 O C, a voltage efficiency of 80% was measured at power densities of 0.5-1 kW/m2. Carbon and hydrogen fuels may be produced simultaneously at lugh efficiency from: (1) natural gas, by thermal decomposition, (2) petroleum, by coking or pyrolysis of distillates, (3) coal, by sequential hydrogasification to methane and thermal pyrolysis of the methane, with recycle of the hydrogen, and (4) biomass, similarly by sequential hydrogenation and thermal pyrolysis. Fuel production data may be combined with direct C and H2 fuel cell operating data for power cycle estimates. Thermal to electric efficiencies indicate 80% HHV [85% LHV] for petroleum, 75.5% HHV [83.4% LHV] for natural gas and 68.3% HHV [70.8% LHV] for lignite coal. Possible benefits of integrated carbon and hydrogen fuel cell power generation cycles are: (1) increased efficiency by a factor of up to 2 over many conventional fossil fuel steam plants, (2) reduced power generation cost, especially for increasing fossil fuel cost, (3) reduced CO2 emission per kWh, and (4) direct sequestration or reuse (e.g., in enhanced oil or NG recovery) of the CO{sub 2} product.

A practical design for an integrated HVDC unit - connected hydro-electric generating station  

SciTech Connect (OSTI)

To date, several authors (see reference list) have proclaimed benefits which can be achieved by integrating HVDC converter stations directly with generating units. The cost of a significant amount of plant and facilities found in conventional schemes is thereby eliminated. So far as is known however, no detailed studies have been done to quantify these benefits. This paper outlines the results of a study made recently by the Manitoba HVDC Research Centre to determine the practicality of such a scheme. To give credence to the results an actual hydro station design was used incorporating a HVDC thyristor valve scheme in a hypothetical situation. Financial and other benefits were determined for this example together with conclusions and recommendations for future specific projects and further areas of study.

Influence of steam on the flammability limits of premixed natural gas/oxygen/steam mixtures  

Science Journals Connector (OSTI)

Synthesis gas (Syngas) is an intermediate in a variety of industrial processes. Its production is energy and capital intensive and any improvement of existing technologies allowing simpler and economic production is of great interest. Recently, a new method known as short contact time-catalytic partial oxidation (SCT-CPO) has been developed into a commercial technology [1–4]. SCT-CPO is an entirely heterogeneous catalytic process converting premixed flammable feedstocks inside a very small reactor. In order to ensure safety and a high selectivity towards CO and H2 it has been important to determine and understand flammability properties of the gaseous reactant mixtures. Here we report on the results obtained within a windowed tube reactor equipped with multiple photodetectors and pressure transducers that has allowed the study of ignition, flame propagation, and explosion characteristics of gas mixtures similar to those used as reactants in the SCT-CPO reactor. The tests were conducted at various pressures with different amounts of steam and two different compositions of natural gas (NG). A flammability boundary for each mixture, based on normalized pressure and mole fraction of steam, was determined. The results conclude that these mixtures’ flammability could be suppressed in two very different ways. Depending on the adiabatic flame temperature of the mixture, suppression could be caused by steam's chemical influence increasing chain-termination or by a large amount of steam decreasing the reaction zone temperature.

The value of steam turbine upgrades  

SciTech Connect (OSTI)

Technological advances in mechanical and aerodynamic design of the turbine steam path are resulting in higher reliability and efficiency. A recent study conducted on a 390 MW pulverized coal-fired unit revealed just how much these new technological advancements can improve efficiency and output. The empirical study showed that the turbine upgrade raised high pressure (HP) turbine efficiency by 5%, intermediate pressure (IP) turbine efficiency by 4%, and low pressure (LP) turbine efficiency by 2.5%. In addition, the unit's highest achievable gross generation increased from 360 MW to 371 MW. 3 figs.
