Modern Gas Turbine Systems


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

Combined Cycle Driven Efficiency for Next Generation Nuclear Power Plants


Book Description

The second edition of this book includes the most up-to-date details on the advantages of Nuclear Air-Brayton Power Plant Cycles for advanced reactors. It demonstrates significant advantages for typical sodium cooled reactors and describes how these advantages will grow as higher temperature systems (molten salts) are developed. It also describes how a Nuclear Air-Brayton system can be integrated with significant renewable (solar and wind) energy systems to build a low carbon grid. Starting with basic principles of thermodynamics as applied to power plant systems, it moves on to describe several types of Nuclear Air-Brayton systems that can be employed to meet different requirements. It provides estimates of component sizes and performance criteria for Small Modular Reactors (SMR). This book has been revised to include updated tables and significant new results that have become available for intercooled systems in the time since the previous edition published. In this edition also, the steam tables have been updated and Chapters 9 and 10 have been rewritten to keep up with the most up-to- date technology and current research.




Coal


Book Description

The U.S. Department of Energy (DOE) was given a mandate in the 1992 Energy Policy Act (EPACT) to pursue strategies in coal technology that promote a more competitive economy, a cleaner environment, and increased energy security. Coal evaluates DOE's performance and recommends priorities in updating its coal program and responding to EPACT. This volume provides a picture of likely future coal use and associated technology requirements through the year 2040. Based on near-, mid-, and long-term scenarios, the committee presents a framework for DOE to use in identifying R&D strategies and in making detailed assessments of specific programs. Coal offers an overview of coal-related programs and recent budget trends and explores principal issues in future U.S. and foreign coal use. The volume evaluates DOE Fossil Energy R&D programs in such key areas as electric power generation and conversion of coal to clean fuels. Coal will be important to energy policymakers, executives in the power industry and related trade associations, environmental organizations, and researchers.




Electricity: Humanity's Low-carbon Future - Safeguarding Our Ecological Niche


Book Description

Climate change is no longer deniable. Neither is the fact that greenhouse gas emissions due to human activities need to be mitigated. The question is how to rapidly transit to an increasingly low-carbon world while essentially sustaining the quality of life of the fortunate and providing better lives for the less fortunate.The challenge is to decarbonize both energy consumption and production with electricity at the core of energy systems.Perhaps Energia, a fictitious country whose 50 million inhabitants endorse climate change objectives and that embodies the energy mutations proposed by the authors, has the answers. Along with Energia, four families living in Africa, America, Asia and Europe who represent us, the consumer, set the stage for the book's discussions.On the user front, the presentation primarily focuses on energy consumption at home and for transport. On the energy production front, the focus shifts to the integration of renewables with fossil and nuclear energy. The book's coverage includes crucial systemic issues related to energy storage, electric power systems and multi-energy systems. In a dedicated chapter, the authors put forward their energy and environmental public policy observations and proposals, including a carbon fee scheme.Electricity is written for readers interested and concerned by the environmental and energy challenges we face, and who seek to participate, as well-informed citizens, in discussions on future energy-related options. The book provides a balanced, factual and unemotional presentation of readily available energy systems and technologies which, when widely deployed, can contribute, both short and long term, toward a low-carbon and electricity-centered world.
