Book Description :

Modern gas turbine power plants represent one of the most efficient and economic conventional power generation technologies suitable for large-scale and smaller scale applications. Alongside this, gas turbine systems operate with low emissions and are more flexible in their operational characteristics than other large-scale generation units such as steam cycle plants. Gas turbines are unrivalled in their superior power density (power-to-weight) and are thus the prime choice for industrial applications where size and weight matter the most. Developments in the field look to improve on this performance, aiming at higher efficiency generation, lower emission systems and more fuel-flexible operation to utilise lower-grade gases, liquid fuels, and gasified solid fuels/biomass. Modern gas turbine systems provides a comprehensive review of gas turbine science and engineering. The first part of the book provides an overview of gas turbine types, applications and cycles. Part two moves on to explore major components of modern gas turbine systems including compressors, combustors and turbogenerators. Finally, the operation and maintenance of modern gas turbine systems is discussed in part three. The section includes chapters on performance issues and modelling, the maintenance and repair of components and fuel flexibility. Modern gas turbine systems is a technical resource for power plant operators, industrial engineers working with gas turbine power plants and researchers, scientists and students interested in the field. Provides a comprehensive review of gas turbine systems and fundamentals of a cycle Examines the major components of modern systems, including compressors, combustors and turbines Discusses the operation and maintenance of component parts

Book Description :

Recent years have seen acceleration in the development of cleaner energy systems. In Europe and North America, many old coal-fired power plants will be shut down in the next few years and will likely be replaced by combined cycle plants with higher-efficiency gas turbines that can start up and load quickly. With the revival of nuclear energy, designers are creating smaller nuclear reactors of a simpler integrated design that could expand the application of clean, emission-free energy to industry. And a number of manufacturers now offer hybrid cars with an electric motor and a gasoline engine to charge the batteries on the move. This would seem to be the way forward in reducing transport emissions, until countries develop stronger electricity supply systems to cope with millions of electric cars being charged daily. Greener Energy Systems: Energy Production Technologies with Minimum Environmental Impact tackles the question of how to generate enough electricity, efficiently and with minimum environmental impact, to meet future energy needs across the world. Supplemented with extensive figures and color photographs, this book: Traces the development of electricity supply Explains energy production risks and how major accidents have influenced development Discusses the combined cycle, the preferred system for power capacity expansion in much of the world Looks at combined heat and power Addresses whether coal can continue to be a fuel for power generation Examines nuclear power generation Asks why shipping has not followed some of the world's navies into nuclear propulsion Considers how to electrify more transport systems Reviews the current state of renewable systems, particularly hydro and solar The book defines the key elements of greener energy systems, noting that they must be highly efficient, with rapid start up and loading; produce minimum emissions; and use simpler technology. The author has more than forty years of experience as an international journalist reporting on power-generation technologies and energy policies around the world. He concludes that there is no place for coal and that combined cycle, hydro, solar, and biomass must complement nuclear energy, which must serve more applications than just generating electricity.

Book Description :

A heat pump system can produce an amount of heat energy that is greater than the amount of energy used to run the heat pump system. Thus, a heat pump system is considered to be a machine system that can use energies efficiently, as is the load leveling air-conditioning system utilizing unutilized energies at high levels. Adaptations of gas turbines for industrial, utility, and marine-propulsion applications have long been accepted as means for generating power with high efficiency and ease of maintenance. Cogeneration with gas turbine is frequently defined as the sequential production of useful thermal energy and shaft power from a single energy source. For applications that generate electricity, the power can either be used internally or supplied to the utility grid. This Special Issue intends to provide an overviews of the existing knowledge related with various aspects of “Small-Scale Energy Systems with Gas Turbines and Heat Pumps”, and contributions on, but not limited to the following subjects were encouraged: wake of stator vane to improve sealing effectiveness; gas turbine cycle with external combustion chamber for prosumer and distributed energy systems; computational simulation of gas turbine engine operating with different blends of biodiesel; experimental methodology and facility for the engine performance and emissions evaluation using jet and biodiesel blends; experimental analysis of an air heat pump for heating service; hybrid fuel cell-Brayton cycle for combined heat and power; design analysis of micro gas turbines in closed cycles. Seven papers were published in the Special Issue out of a total of 12 submitted.

Book Description :

This report summarizes the progress made in development of Direct FuelCell/Turbine (DFC/T{reg_sign}) power plants for generation of clean power at very high efficiencies. The DFC/T system employs an indirectly heated Turbine Generator to supplement fuel cell generated power. The concept extends the high efficiency of the fuel cell by utilizing the fuel cell's byproduct heat in a Brayton cycle. Features of the DFC/T system include: electrical efficiencies of up to 75% on natural gas, minimal emissions, reduced carbon dioxide release to the environment, simplicity in design, direct reforming internal to the fuel cell, and potential cost competitiveness with existing combined cycle power plants. Proof-of-concept tests using a sub-MW-class DFC/T power plant at FuelCell Energy's (FCE) Danbury facility were conducted to validate the feasibility of the concept and to measure its potential for electric power production. A 400 kW-class power plant test facility was designed and retrofitted to conduct the tests. The initial series of tests involved integration of a full-size (250 kW) Direct FuelCell stack with a 30 kW Capstone microturbine. The operational aspects of the hybrid system in relation to the integration of the microturbine with the fuel cell, process flow and thermal balances, and control strategies for power cycling of the system, were investigated. A subsequent series of tests included operation of the sub-MW Direct FuelCell/Turbine power plant with a Capstone C60 microturbine. The C60 microturbine extended the range of operation of the hybrid power plant to higher current densities (higher power) than achieved in initial tests using the 30kW microturbine. The proof-of-concept test results confirmed the stability and controllability of operating a fullsize (250 kW) fuel cell stack in combination with a microturbine. Thermal management of the system was confirmed and power plant operation, using the microturbine as the only source of fresh air supply to the system, was demonstrated. System analyses of 40 MW DFC/T hybrid systems, approaching 75% efficiency on natural gas, were carried out using CHEMCAD simulation software. The analyses included systems for near-term and long-term deployment. A new concept was developed that was based on clusters of one-MW fuel cell modules as the building blocks. The preliminary design of a 40 MW power plant, including the key equipment layout and the site plan, was completed. The process information and operational data from the proof-of-concept tests were used in the design of 40 MW high efficiency DFC/T power plants. A preliminary cost estimate for the 40 MW DFC/T plant was also prepared. Pilot-scale tests of the cascaded fuel cell concept for achieving high fuel utilizations were conducted. The tests demonstrated that the concept has the potential to offer higher power plant efficiency. Alternate stack flow geometries for increased power output and fuel utilization capabilities were also evaluated. Detailed design of the packaged sub-MW DFC/T Alpha Unit was completed, including equipment and piping layouts, instrumentation, electrical, and structural drawings. The lessons learned from the proof-of-concept tests were incorporated in the design of the Alpha Unit. The sub-MW packaged unit was fabricated, including integration of the Direct FuelCell{reg_sign} (DFC{reg_sign}) stack module with the mechanical balance-of-plant and electrical balance-of-plant. Factory acceptance tests of the Alpha DFC/T power plant were conducted at Danbury, CT. The Alpha Unit achieved an unsurpassed electrical efficiency of 58% (LHV natural gas) during the factory tests. The resulting high efficiency in conversion of chemical energy to electricity far exceeded any sub-MW class power generation equipment presently in the market. After successful completion of the factory tests, the unit was shipped to the Billings Clinic in Billings, MT, for field demonstration tests. The DFC/T unit accomplished a major achievement by successfully completing 8000 hours of operation at the Billings site. The Alpha sub-MW DFC/T power plant unit was returned to the factory for post-operation inspection and analysis. The success of the Alpha Unit operation in the field and achievement of the ultra-high efficiency of 58%, triggered the establishment of a MW-scale commercial product design and development program. Design of a 3 MW (nominal rating) DFC/T Power Plant was completed with an electrical efficiency approaching 60+% LHV of natural gas depending on the design and performance of the gas turbine. Development efforts incorporated lessons learned from the Alpha sub-MW DFC/T power plant demonstration, as well as design features from FCE's commercial product offerings, the DFC1500 and DFC3000 MW-class simple cycle power plants. The 3 MW DFC/T power plant is anticipated to be a superb alternative for large distributed generation applications in locations with high cost-of-electricity.

Energy efficiency is finally a common sense term. Nowadays almost everyone knows that using energy more efficiently saves money, reduces the emissions of greenhouse gasses and lowers dependence on imported fossil fuels. We are living in a fossil age at the peak of its strength. Competition for securing resources for fuelling economic development is increasing, price of fuels will increase while availability of would gradually decline. Small nations will be first to suffer if caught unprepared in the midst of the struggle for resources among the large players. Here it is where energy efficiency has a potential to lead toward the natural next step - transition away from imported fossil fuels! Someone said that the only thing more harmful then fossil fuel is fossilized thinking. It is our sincere hope that some of chapters in this book will influence you to take a fresh look at the transition to low carbon economy and the role that energy efficiency can play in that process.

Book Description :

This volume focuses on a few renewable energy sources, viz. wind energy plus energy from water movement and natural temperature differences that in principle could provide enormous energy resources. Energy from wind has been a rapidly growing source of energy as wind turbines have grown in size and especially as wind turbines have moved offshore. Hydroelectric dams have continued to be used as energy sources particularly in developing countries. Other energy sources using water, including waves and tidal sources, are also discussed in this volume. Finally, the volume discusses differences between deep and surface ocean temperatures plus the extraction of energy from the earth's extremely large energy resource of magma deep below the surface. These latter two energy resources in particular require further development and the current book describes the latest advances coupled with pointing possible paths forward.

Book Description :

Gas turbines are becoming increasingly used as power generators for a wide variety of applications around the world. Originally they were developed solely for aircraft propulsion where their inherent low specific weight (i.e. mass/unit power) made them essential for high speed flight. For this particular purpose they have been developed to a high degree of efficiency both thermodynamically and mechanically. The significant of this study is to increase the performance of the gas turbine in term of the efficiency. The lower efficiency of the gas turbine will effect to the performance of the gas turbine itself, the waste of the fuel because of the unburned hydrocarbon and the impact to the environment, while the gas turbine with a incomplete combustion. To increase the performance in term of efficiency, the gas generator speed is controlled from 1500 rotary per second to 1250 rotary per second. In order to increase the efficiency of the gas turbine, the power output must high, because it is proportional to the efficiency. Besides low fuel consumption is also important to evaluate an efficient gas turbine because it is inversely proportional to efficiency of the unit. From the experiment, is at a speed of 1400 rotary per second, it is the optimum speed that make the gas turbine running at the highest efficiency. The fuel rate consumption at this speed is 1.48E-03kg/s and the power produce is 905.04W. In conclusion, the optimum speed to run the unit at a high efficiency is at 1400 rotary per second which has produced high power output and low fuel consumption. As a recommendation, to further improve the overall performance of the gas turbine unit, air to fuel ratio must be analyzed, in order to find an optimum air to fuel ratio in the combustion chamber.-Author.
