Abstract:

The main aim of the current study is to analyze advantages and shortcomings of horizontal and vertical types of steam generator design. Design solutions and experience of operation of steam generators of horizontal type accepted in Russia and of vertical type applied by Westinghouse, Combustion Engineering, Siemens, Mitsubishi, Doosan were analyzed within the framework of the present study. It was established that steam generator equipment of horizontal type is characterized by disadvantages of design, technological and operational nature. Thus, horizontal steam generators with dimensions permissible for railroad transportation and, for VVER-1200 with reactor vessel diameter equal to 5 m, by water transport as well, have exhausted the possibilities for further significant increase of the per unit electric power. The demonstrated advantages of vertical-type steam generators are as follows: 1) absence of stagnant zones within the second cooling circuit; 2) uniformity of heat absorption efficiency of the heating surface that ensures improved conditions for moisture separation; 3) increased temperature drop with parameters of generated steam elevated by 0.3 – 0.4 MPa. Conclusion was made on the advisability of introduction of steam generators with vertical-type layout in the Russian nuclear power generation.

Abstract:

THE PURPOSE. To consider various variants of thermal schemes of power plants and to assess the main technical and economic parameters. The article presents the results of the development of schemes of electric power plants with a capacity of up to 100 kW with a steam-generating hydrogen-oxygen plant for modeling and selecting effective options for thermal schemes of microgeneration power plants at the stage of design and development of energy systems. METHODS. The analysis of the proposed variants of thermal schemes with a hydrogen-oxygen steam generator, including circuit solutions of micro-gas turbine installations with a hydrogen-oxygen steam generator, a scheme of a steam-gas installation with a hydrogen-oxygen steam generator and intermediate steam superheating, a scheme of a steam-turbine installation with a hydrogen-oxygen steam generator, a scheme of a steam-turbine installation with a hydrogen-oxygen steam generator and a single-stage intermediate steam superheating, is performed, the scheme of a steam turbine installation with a hydrogen-oxygen steam generator and an intermediate superheat of steam and a steam cooler. RESULTS. A variant of the thermal scheme is proposed, which will allow determining the approach to estimating the fuel component of the production cost of heat and electricity for domestic power plants. The article describes a chemical method for producing hydrogen under laboratory conditions in hydrogen generators based on the hydrolysis of a solid reagent-aluminum-in a reaction vessel, in which the contact of aluminum particles occurs in the liquid phase of an aqueous solution of caustic soda. A feature of the proposed method is the possibility of regulating the flow rates in the supply lines of an aqueous suspension of aluminum and an aqueous solution of caustic soda, which can significantly improve the quality of regulation and reduce the cost of operating such systems. To a large extent, the creation of such systems becomes possible if there is a demand for the generated electrical energy, which determines the need to ensure high values of technical and economic indicators of the operation of power plants. CONCLUSHION. Calculated estimates have shown that the specific consumption of conventional fuel for the production of electric energy by microgeneration systems based on gas turbine units with a hydrogen generator with a capacity of 5-100 kW ranges from 0.098 to 0.117 kg/kWh.

Abstract:

Steam generators for NPPs are the important large-sized metal consuming equipment of nuclear power installations. Efficiency of steam generator operation determines the overall service life of the whole nuclear facility. The main aim of the current study is to analyze advantages and shortcomings of horizontal and vertical types of steam generator design. This analysis is aimed at the development of recommendations for designing advanced steam generators for future Russian units of NPPs with VVER reactors of increased power. Design solutions and fifty-year experience of operation of 400 steam generators of horizontal type accepted in Russia and of vertical type applied by Westinghouse, Combustion Engineering, Siemens, Mitsubishi, Doosan were analyzed within the framework of the present study. Advantages and drawbacks of both types of equipment determining the development of conditions of the operating processes were also identified and systematized. Currently NPPs equipped with VVER are characterized with extended surface area of containment shells due to the application of four-loop design configuration and horizontal-type steam generators. It was established that steam generator equipment of horizontal type is characterized by such inherent disadvantages of design, technological and operational nature as the following: 1) small height and volume of the vapor space above the evaporation surface reducing separation capabilities and the capacity of the equipment as a whole; 2) impossibility of organizing separate single-phase pre-boiling section. Because of the above, horizontal steam generators with dimensions permissible for railroad transportation and, for VVER-1200 with reactor vessel diameter equal to 5 m, by water transport as well, have exhausted the possibilities for further significant increase of the per unit electric power. The demonstrated advantages of vertical-type steam generators were as follows: 1) absence of stagnant zones within the second cooling circuit, and, consequently, of hold-ups in them; 2) uniformity of heat absorption efficiency of the heating surface ensuring, as well, improved conditions for moisture separation; 3) high degree of moisture removal from steam-water mixture due to the combination of moisture separating elements of chevron and swirl-vane types; 4) increased temperature drop with parameters of generated steam elevated by 0.3 – 0.4 MPa. Conclusion was made on the advisability of introduction of steam generators with vertical-type layout in the Russian nuclear power generation. Practical tasks that need to be addressed in order to ensure introduction of vertical steam generators at NPPs with high-power VVER reactors were formulated.

Abstract:

Subject and Purpose. The present paper is concerned with the method of surface schooping of materials using high-frequency torch discharge (HFTD) and glycerol vapor as a base for dissolving activating additives to the working gas. To approach the problem, a steam generator is employed in an effort to improve the HFTD catalytic performance in the activation of surfaces and deposition of coatings on them. The purpose is to develop a design technique of a steam generator intended for making a proper gas environment in the HFTD burning area. The discussed design techniques seek to enhance efficiency of the self-contained steam generator with allowance for its small size compared to the wavelength. Methods and Methodology. The analysis of the glycerol vapor behavior in the HFTD plasma depends on the knowledge of glycerol molecule ionization potential in the electron impact case. To find out about the measure to which the glycerol vapor affects the HFTD current, a known calcium ionization potential is used as a defined point. The heating elements as part of the steam generator are designed in terms of thermal design methodology adopted in the electroheating machine making. The calculation formulas of the running time ratios of the steam generator with various heating elements and energy efficiencies have been obtained in terms of galvanic cell theory. Results. It has been shown that glycerol vapor itself cannot affect the HFTD current. For the HFTD excitation, the microwave region has been chosen. In cooperation with activating additives to the discharge plasma, this factor also adds to the HFTD current increase. Hence, the HFTD catalytic performance depends not only on the HFTD energy and its excitation field frequency but on the glycerol-dissolved additives as well. A special design has been developed for the heating element as part of a small-size steam generator. Reference tables have been composed, enabling one to pick up a prpoper diameter and number of parallel connected wires in the spiral coil. Conclusion. A good use of glycerol vapor as a base for vaporous fluxes and activating additives to the HFTD working gas has been shown. The developed design technique concerning the heating element of the steam generator optimizes its heating circuit. Specifically, it enhances the steam generation and reduces the power consumption of the steam generator running on the galvanic cell. Second, it makes it possible to use stainless-steel spiral heating coils in regime of automatic temperature control.

Abstract:

This article presents an overview of gas turbine combined cycle (CCGT) power plants. Modern CCGT power plants are producing electric power as high as half a gigawatt with thermal efficiencies approaching the 60% mark. In a CCGT power plant, the gas turbine is the key player, driving an electrical generator. Heat from the hot gas turbine exhaust is recovered in a heat recovery steam generator, to generate steam, which drives a steam turbine to generate more electrical power. Thus, it is a combined power plant burning one unit of fuel to supply two sources of electrical power. Most of these CCGT plants burn natural gas, which has the lowest carbon content of any other hydrocarbon fuel. Their near 60% thermal efficiencies lower fuel costs by almost half compared to other gas-fired power plants. Their installed capital cost is the lowest in the electric power industry. Moreover, environmental permits, necessary for new plant construction, are much easier to obtain for CCGT power plants.

Abstract:

The objective of this paper is to illustrate the benefits of the influence of the steam and oxyhydrogen gas (HHO) on the composition of emitted exhaust gases and energy usage of operating the internal combustion engine (ICE) that drives a generator-powered battery electric vehicle (BEV). The employed internal combustion generating sets can be used as trailer mounted electric energy sources allowing one to increase the range of BEV vehicles, mainly during long distance travel between cities. The basic configurations of hybrid and electric propulsion systems used in a given Electric Vehicles (xEV) includes all types of Hybrid Electric Vehicles (xHEV) and Battery Electric Vehicles (xBEV), which are discussed. Using the data collected during traction tests in real road traffic (an electric car with a trailer range extender (RE) fitted with ICE generators (5 kW petrol, 6.5 kW diesel), a mathematical model was developed in the Modelica package. The elaborated mathematical model takes into account the dynamic loads acting on the set of vehicles in motion and the electric drive system assisted by the work of RE. Conducted tests with steam and HHO additives for ICE have shown reduced (5–10%) fuel consumption and emissions (3–19%) of harmful gases into the atmosphere.

Abstract:

Abstract This Bachelor thesis has been written at the Blekinge Institute of Technology. The thesis describes electricity production in Shoaiba Steam Power plant in Saudi Arabia. Shoaiba Power Plant is located 100 km South of Jeddah city in Saudi Arabia. Total power production ability reaches 4400 MW. Shoaiba Power Plant has two stages and is constructed with 11 units, each unit produces 400 MW at line voltage 24 kV and line current 16 kA. Main pieces of equipment and their function in the station are as follows: A Steam Generator (boiler), produces steam by burning natural gas or crude oil in the furnace. The steam is superheated and is passed into a steam turbine, which converts the thermal energy of the steam into mechanical power, in form of rotary motion. The turbine drives a generator, which converts the rotary energy of the turbine into electric power. Steam generator, steam turbine and electrical generator are components that are described in the thesis. When the flow of steam to the turbine is controlled, then the amount of thermal energy that changes to mechanical energy in the steam turbine is controlled. The electrical generator is where the final energy conversion takes place. The mechanical energy from the turbine is converted by the generator into electrical energy, which is transmitted to the service area by help of electrical transmission lines. The plant cycle is an essential part of the energy flow path. Without the plant cycle, the conversion of thermal energy into mechanical energy would not occur, The plant cycle is a closed loop that allows the same water to be used over and over again. Always, the power plants are situated far from residential areas and located outside cities and close to the sea, because the steam is produced from seawater. The advantages of the steam power stations are as follows: They can produce high amounts of electrical energy from small amounts of fuel. They have low initial costs, obstetrics and maintenance costs are not high, and the stations do not need much space to be built and they have usually high capacity. The disadvantages of steam stations are the following: They cause environmental pollution, they have low efficiency, and require very big quantities of cooling water, and the stations must be built away from populated areas.
Conclusion: Converting in steam power plant is one of many ways to produce electrical energy in the world. It can be done in any country because it can be done with different chemical sources. In Saudi Arabia we use oil, because it easier and cheaper than any other chemical source for us. As any country would use what is better for them. The thesis has described circulation system in Shoaiba power plant by converting chemical energy to thermal energy in the boiler, then the turbine converts thermal energy to mechanical energy. Then the mechanical energy is converted to electrical energy in the generator. The advantages of the steam stations are as follows: production of high amounts of electrical energy from small amounts of fuel, low cost of the initial costs, obstetrics and maintenance costs are not high, the station does not need much space to build and they are usually high capacity. The disadvantages of steam stations are the following: environmental pollution, low efficiency, requires very big amounts of cooling water, and these stations must be built away from population areas.

Abstract:

In recent years, the trend for continuous down-scaling of CMOS device dimension has made analog design much more challenging. This trend has been a major driving force in trying to find new approaches for designing common analog building blocks. One such block is the bandgap voltage reference. This common circuit serves the purpose of generating a fixed DC voltage reference and has uses in a wide variety of applications.
This thesis introduces a new way of generating a programmable DC voltage reference with similar performance to the traditional means. This voltage reference generator is based on periodic bit-stream modulation and relies on simple digital logic combined with a low pass filter (LPF) to demodulate the DC reference level. The advantage of the proposed DC voltage reference lies in its immunity to technology scaling as it is mostly digital. The programmability of the proposed circuit also makes it usable as a digital to analog converter (DAC).
Through simulation and experimental results obtained using a set of integrated circuits implemented in 0.35 mum, 0.25 mum and 0.18 mum CMOS technologies a number of conclusions are reached. The tradeoffs between the two different bit-stream modulation scheme, pulse width modulation (PWM) and pulse density modulation (PDM), are compared yielding PDM as the best approach. The analysis and simulation of a new synthesis method will demonstrate that high-order passive RC filters yield the most attractive realization of the LPF. Experimental results will also demonstrate that performance due to temperature variations comparable to bandgap references can be achieved. A set of experiments will also demonstrate the excellent performance of this voltage reference when used as a DAC. Lastly, the use of asynchronous logic for generating periodic bit-streams will be shown to yield promising results.

Abstract:

Mitochondria are essential for the viability of mammalian cells and provide a compartment for specific chemical reactions. Cellular respiration -- the main mitochondrial function -- is tightly connected with ROS production: the mitochondrial electron transport chain complexes I and III are the main ROS sources in mammalian cells. It has been reported that complex I and complex III activities are essential for cell cycle, apoptosis and stem cell differentiation (Spitkovsky et al., 2004; Varum et al., 2009; Lee et al., 2011; Ma et al., 2011; Tormos et al., 2012). In our work, we aimed to investigate the role of mitochondrial electron transport chain activity in the regulation of the differentiation potential and to unravel signaling pathways that could participate in this regulation. As a model, we used the P19 pluripotent stem cell line that can be easily differentiated into trophoblasts, expressing intermediate filaments cytokeratin 8/18, and neurons, which express cytoskeleton protein beta-III-tubulin. We first showed that both trophoblast and neural differentiation of P19 cells were accompanied by activation of cellular respiration. The analysis of respiratory chain complexes and supercomplexes, however, showed that undifferentiated P19 cells, as well as their differentiated derivatives did not differ in their respiratory machinery, including functional respirasomes. While undifferentiated cells did not use respiration as the main energy source, cellular respiration was activated during differentiation, indicating that oxidative metabolism was important for efficient differentiation. To investigate the potential role of mitochondrial electron transport chain activity we monitored the influence of a disrupted electron flow on the differentiation of P19 cells. We found that the activity of complex I and complex III influenced the differentiation potential of the pluripotent P19 cell line: the presence of complex I and complex III inhibitors rotenone, antimycin A, or myxothiazol increased the amount of cytokeratin 8/18+ cells during trophoblast differentiation, but almost completely prevented the formation of neuron-like beta-III-tubulin+ cells during neuron differentiation. Moreover, a low oxygen level (1 % O2 vs 21 % O2 in atmosphere) - the final electron acceptor - had the same effect on differentiation. These data suggest that mitochondrial electron transport chain activity contributes to the regulation of differentiation. The presence of complex I and complex III inhibitors, as well as oxygen scarcity, increase ROS production. We suggested that increased ROS level could explain the observed effects. By visualizing mitochondrial superoxide production with a specific dye – MitoSox - we confirmed that rotenone, antimycin A, myxothiazol, as well as low oxygen conditions, increased the superoxide level. These results suggest that the observed changes of the differentiation potential of P19 cells are associated with ROS production. To prove this idea, we differentiated P19 cells in presence of paraquat – a known ROS inducer. In line with our hypothesis paraquat promoted trophoblast differentiation. The received results suggest that the mitochondrial electron transport chain activity regulates differentiation through the ROS level. ROS are secondary messengers that participate in numerous processes including cell proliferation and differentiation. We aimed to predict the signal pathway that connects ROS level in stem cells and their differentiation potential. For this purpose, we performed a microarray analysis and compared the gene expression profiles of cells grown under hypoxia or in the presence of the complex III inhibitor myxothiazol with untreated control cells. The expression analysis revealed p53 as a transcriptional factor that impacts the differentiation potential in treated cells. p53 is a known redox-sensing molecule (Bigarella et al., 2014) that influences the differentiation potential through cell cycle control (Maimets et al., 2008). This observation is in line with our results and suggests that p53 may regulate the differentiation potential of P19 cells. We are planning to investigate the role of p53 signaling in the regulation of cell cycle and differentiation potential of P19 cell line.

As usinas siderúrgicas caracterizam-se, sob o ponto de vista energético, pela grande intensidade de energia empregada em processos de redução do minério de ferro, fusão das matérias-primas e refino do aço líquido obtido. Quanto aos processos utilizados para a produção de aço, destacam-se o emprego de duas rotas tecnológicas: usinas integradas e semi-integradas (mini-mills). As usinas integradas possibilitam a redução do minério de ferro até ferro-gusa e, a partir deste, a obtenção do aço. As mini-mills caracterizam-se pelo emprego de sucatas metálicas, ferro-gusa ou ferro esponja como matérias-primas e pela obtenção, como produtos, de diferentes tipos de aço. Na operação de refino do aço líquido produzido comumente é necessário o emprego de desgaseificadores a vácuo para remoção de contaminantes e, consequentemente, atendimento às especificações do produto acabado. Com isso, as mini-mills demandam potência elétrica para os processos de fusão do aço e vapor superaquecido para obtenção de vácuo nos ejetores do processo de desgaseificação. Para atendimento a legislações ambientais, sistemas de despoeiramento devem ser aplicados às aciarias, disponibilizando grandes vazões de gases quentes provenientes do forno elétrico. A operação do sistema de despoeiramento indica expressivo potencial para recuperação de calor em processos siderúrgicos. Na presente dissertação propõe-se a coleta e análise de dados de operação do sistema de despoeiramento de um forno elétrico a arco de uma mini-mill brasileira, visando concepção e análise técnica-econômica de uma central de cogeração associada à recuperação de calor destes gases do sistema de despoeiramento
The steel industry can be characterized by its high demand of energy in the process of reduction and production of pig iron and steel. For the production of steel the following routes can be highlighted: integrated plants and mini-mills. Integrated plants are used for production steel from iron ore, allowing the reduction of iron ore until pig iron, and pig iron to steel. Mini-mills are used for production of steel through metallic scraps and pig iron. In a mini-mill, the transformation of metallic scraps and pig iron to steel is reached in melting shop areas. The melting shop areas adopt vacuum degassers as a commonly equipment to remove contaminants of liquid steel and consequently reach requirements of finished products. As a consequence, in a melting shop, electricity is applied in electric arc furnaces and overheated steam is applied in vacuum degassers. According to environmental restrictions these melting shops are integrated with dust collectors. The dust collected in electric arc furnaces has great amount of energy and can express a high potential to heat recovering systems. The present dissertation has purpose in collect and analyzes data from an electric arc furnace with a dust collector in a Brazilian mini-mill for developing a thermal-economic analysis of a cogeneration plant integrated in this mini-mill.

Abstract:

There is a continually growing need for mass transport and along with customer desire for greater comfort and speed, its consumption of energy will grow faster still. The fiscal cost of energy plus global warming has spurred efficiency improvement and thoughts now concentrate on fuels. In the UK for major lines for trains, this is electricity generated in a benign fashion in large facilities nominally remote from the train and track. Electric trains tend to be lighter, hence more efficient and demand less maintenance than their diesel counterpart. Similar arguments, including pollution emissions apply to city mass transit systems. For medium density and lower density routes, whether fuel cells or the next generation of IC or GT engines are employed, hydrogen is a prime energy candidate and here we examine its feed, production, distribution, and application, including generator location. Hydrogen from steam hydrocarbon reformers have even been installed in ships. Other countries have similar desires to those of the UK, including Saudi Arabia, but their problems are different and outline examples from Australia and Saudi Arabia are included.

Abstract:

The movement for energy independence coupled with aggressive renewable energy goals and government investment incentives has led the power industry to develop efficient and reliable sources of renewable power. In a power tower system a central Solar Receiver Steam Generator (SRSG) is surrounded by a field of mirrors (heliostats) that focus and concentrate sunlight onto the receiver tubes. The energy from the sunlight is used to generate and superheat steam for electric production. The Ivanpah Solar Electric Generating System (ISEGS) project, located in Ivanpah, CA, consists of three 126 MWg units, to power approximately 140,000 homes. The Ivanpah SRSG’s are forced circulation drum-type boilers with single reheat; located on top of a 400 ft (122 m) steel tower [1]. This paper will discuss the development, constraints, and unique design challenges of the Riley Power Inc. (RPI) SRSG selected for the Ivanpah project. Process descriptions and predicted unit performance are presented, along with comparisons to typical fossil boilers. First of kind concepts and engineering design achievements are discussed for what will be the largest power tower project in the world.

Abstract:

Grand River Dam Authority (GRDA) operates a coal-fired electrical production power plant located thirty miles from Tulsa, Oklahoma. The facility contains two primary turbine-generators, referred to as Unit 1 and Unit 2. Each unit consists of a coal combustion boiler, a steam turbine, an electric generator, pollution control equipment, and auxiliary support equipment. Total maximum facility generating capacity for this plant is 1010 megawatts. ALSTOM Power was awarded a contract by GRDA to upgrade the obsolete control system for its Unit 2 turbine-generator during the fall 2007 outage. The scope included new steam turbine valves actuators, a 3-channel hydraulic safety system, electronic turbine control and protection systems, and a generator automatic voltage regulator, along with associated services and on-site training. Demolition, installation, commissioning and all performance tests had to be completed during a short 3-weeks schedule. The project is now complete; an obsolete control system was replaced with a more efficient, state-of-the-art control system. This paper will discuss and document details concerning this modernization control system.

Abstract:

Advanced ultra-supercritical (A-USC) is a term used to designate a coal-fired power plant design with the inlet steam temperature to the turbine at 700 to 760C (1292 to 1400F). Average metal temperatures of the final superheater and final reheater could run higher, at up to about 815C (1500F). Nickel-based alloy materials are thus required. Increasing the efficiency of the Rankine regenerative-reheat steam cycle to improve the economics of electric power generation and to achieve lower cost of electricity has been a long sought after goal. Efficiency improvement is also a means for reducing the emission of carbon dioxide (CO2) and the cost of capture, as well as a means to reduce fuel consumption costs. In the United States (U.S.), European Union, India, China and Japan, industry support associations and private companies working to advance steam generator design technology have established programs for materials development of nickel-based alloys needed for use above 700C (1292F). The worldwide abundance of less expensive coal has driven economic growth. The challenge is to continue to improve the efficiency of coal-fired power generation technology, representing nearly 50% of the U.S. production, while maintaining economic electric power costs with plants that have favorable electric grid system operational characteristics for turndown and rate of load change response. The technical viability of A-USC is being demonstrated in the development programs of new alloys for use in the coal-fired environment where coal ash corrosion and steamside oxidation are the primary failure mechanisms. Identification of the creep rupture properties of alloys for higher temperature service under both laboratory and actual field conditions has been undertaken in a long-term program sponsored by the U.S. Department of Energy (DOE) and the Ohio Coal Development Office (OCDO). Ultimately, the economic viability of A-USC power plants is predicated on the comparable lower levelized cost of electricity (LCOE) with carbon capture and sequestration (CCS) using either oxy-combustion or post-combustion capture. Using nickel alloy components will drive the design and configuration arrangement of the steam generator relative to the plant. A-USC acceptance depends on achieving the higher functional value and lowering the perceived level of risks as this generation technology appears in a new form.

Abstract:

NuScale Power, Inc. is commercializing a 45 Megawatt electric light water nuclear reactor NuScale Power Module (NPM). Each NPM includes a containment vessel, a reactor vessel, a nuclear reactor core, an integral steam generator, and an integral pressurizer. The NuScale Power Module is cooled by natural circulation. The primary coolant in the Reactor Pressure Vessel is heated in the nuclear core, it rises through a central riser, it spills over and encounters the helical coil steam generator, it is cooled as steam is generated inside the steam generator, and it is again heated in the nuclear core. The Steam Generator also must be designed to provide adequate heat transfer, to allow adequate primary reactor coolant flow, and to provide adequate steam flow to produce the required power output. This paper presents the CFD results that describe the transport phenomena on the heat transfer and fluid flow dynamics in helical coil steam generator tubes. The ultimate goal of the CFD modeling is to predict the steam outlet conditions associated with the chosen helical coil tube geometries, solving the primary and secondary flow region together coupled with the helical coil tube. However, current studies are focused on the primary side with the heat flux boundary condition assigned on the outer surface of the helical coil steam generator. In this study, the ANSYS CFX v. 12.1 [1] was used to solve the three-dimensional mass, momentum and energy equations. The helical coil steam generator has complex geometry and modeling entire geometry requires the enormous memory that is beyond our hardware capability and is not practical. Therefore, geometry was limited to 1 degree of the wedge and 5% of the total length in the middle. Only external flow, single phase flow around the helical coils, is simulated using the standard k-ε model and shear stress transport model. From the results of the numerical simulation, the pressure drop and temperature profiles were determined. It is important to understand thermal hydraulic phenomena for the design and performance prediction of the reactor internal.

Abstract:

Abstract The integrated solar plant concept was initially proposed by Luz Solar International [1] as a means of integrating a parabolic trough solar plant with modern combined cycle power plants. An integrated plant consists of a conventional combined cycle plant, a solar collector field, and a solar steam generator. During sunny periods, feedwater is withdrawn from the combined cycle plant heat recovery steam generator, and converted to saturated steam in the solar steam generator. The saturated steam is returned to the heat recovery steam generator, and the combined fossil and solar steam flows are superheated in the heat recovery steam generator. The increased steam flow rate provides an increase in the output of the Rankine cycle. During cloudy periods and at night, the integrated plant operates as a conventional combined cycle facility. Two studies on integrated plant designs using a General Electric Frame 7(FA) gas turbine and a three pressure heat recovery steam generator are currently being conducted by the authors. Preliminary results include the following items: 1) the most efficient use of solar thermal energy is the production of high pressure saturated steam for addition to the heat recovery steam generator; 2) the quantity of high pressure steam generation duty which can be transferred from the heat recovery steam generator to the solar steam generator is limited; thus, the maximum practical solar contribution is also reasonably well defined; 3) small annual solar thermal contributions to an integrated plant can be converted to electric energy at a higher efficiency than a solar-only parabolic trough plant, and can also raise the overall thermal-to-electric conversion efficiency in the Rankine cycle; and 4) annual solar contributions up to 12 percent in an integrated plant should offer economic advantages over a conventional solar-only parabolic trough power plant.

Full text

Abstract:

Union Electric Company is a summer peaking utility, experiencing peak electrical load demands during the hot summer months. Combustion turbine generators are often used to meet the summer peak demands. However, the generating capability of a combustion turbine decreases as the ambient air temperature increases. When system peak demands are at their highest levels on the hottest days of the year, the generating capacity of the combustion turbines are at their lowest values. This lost generating capacity can be recovered by cooling the air entering the combustion turbines. Various combustion turbine inlet air cooling technologies were investigated for a General Electric Model 7B combustion turbine. The cooling technologies evaluated in the study were evaporative cooling, thermal energy storage (ice), on-line mechanical chiller, direct absorption chiller, steam absorption chiller with heat recovery steam generator (HRSG), and once-through cooling using well water. Conceptual designs, performance estimates, installation and operating costs were developed for each alternative.

Abstract:

Carnegie Mellon University’s departments of Architecture and Mechanical Engineering have teamed with Milwaukee School of Engineering’s Mechanical Engineering department to design and install a biodiesel fueled engine-generator with heat recovery equipment to supply electric and thermal power to an office building on campus, the Intelligent Workplace (IW). The installation was completed in early September 2007, and is currently being commissioned. Full scale testing will begin in early 2008. The turbocharged diesel engine-generator set is operated in parallel with the local electric utility and the campus steam grid. The system is capable of generating 25 kW of electric power while providing 18 kW of thermal power in the form of steam from an exhaust gas boiler. The steam is delivered to a double-effect Li-Br absorption chiller, which supplies chilled water to the IW for space cooling in the summer or hot water for space heating in the winter. Furthermore, the steam can be delivered to the campus steam grid during the fall and spring when neither heating nor cooling is required in the IW. Additionally, thermal energy will be recovered from the coolant to provide hot water for space heating in the winter, and for regenerating a solid desiccant dehumidification ventilation system in summer. All relevant temperatures, pressures, and flows for these systems are monitored via a building automation system. Pressure versus time measurements can be recorded in each cylinder of the engine. Emissions of nitric oxide (NO), nitrous oxide (NO2), Particulate Matter (PM), and carbon dioxide (CO2) are also monitored. Upon completion of this installation and the system performance testing, the operation of the engine generator with its heat recovery components will be integrated with the other HVAC components of the IW including a parabolic trough solar thermal driven LiBr absorption chiller, a solid desiccant dehumidification ventilation system, and multiple types of fan coils and radiant heating and cooling devices. This energy supply system is expected to reduce the IW’s primary energy consumption by half in addition to the 75% energy savings already realized as compared to the average US office space.

Abstract:

The gas turbine is not limited to single service applications such as power generation or mechanical drive service. An application has been developed recently to use an industrial gas turbine to drive an electric generator for power while at the same time contributing to the heat balance of a refinery unit. Specifically, a G. E. Frame 5 gas turbine installed with a hydrogen reformer furnace can significantly reduce the overall heat input required by capturing the waste heat in the exhaust gas to preheat the feed to the furnace and to generate high pressure steam for the owner’s refinery steam system. The gas turbine selected for the projects described in this paper is the G.E. Frame 5, model “R” (5271 RA). The model “R” was originally described as a “single shaft mechanical drive” turbine but easily adapted to generator drive. The design is some 30 years old as it was developed in the 1960’s. The term “single shaft mechanical drive” is somewhat strange to us in the process industries as we’re more accustomed to mechanical drive gas turbines designed with two shafts for speed control purposes. Many of the design / construction features of this model make it ideally suited for this application. The higher cost of fuels, and electrical power contribute significantly to making the economics attractive. First of all the heat of the turbine exhaust gas will reduce the fuel required for firing to heat the feed to the furnace. The steam generated in the heat recovery section then contributes to generating power in the steam side in the steam turbine. The results are fuel savings and electric power purchase savings. The steam turbine portion of the cycle is designed to vary with the owner’s steam system and balance. For that reason the steam turbine includes a high pressure inlet, medium pressure steam chest for extraction, a low pressure steam chest designed for induction or extraction and a surface condenser to condense the steam passed through. Fuel flexibility is a major consideration of the unit design. Natural gas or methane rich gas is a base fuel that the gas turbine will fire most of the time. Alternate fuels however, such as propane or butane are commonly available in a refinery and could be fired in the gas turbine as currently configured.
