The gas turbine is a power plant that produces a great amount of energy for its size and weight and thus has found increasing service in the past 20 years in the petrochemical industry and utilities throughout the world. The gas turbine's compactness, weight, and multiple fuel applications make it a natural power plant for offshore platforms.This second edition is not only an updating of technology, which has seen a great leap forward in the 1990s, but also a rewriting of various sections to better answer concerns about emissions, efficiency, mechanical standards and codes, and new materials and coatings. At a time when energy costs are high, this important handbook expertly guides those seeking optimum use of each unit of energy supplied to a gas turbine.In this book, the author has assimilated the subject matter (including diverse views) into a comprehensive, unified treatment of gas turbines. The author discusses the design, fabrication, installation, operation, and maintenance of gas turbines. The intent of this book is to serve as a reference text after it has accomplished its primary objective of introducing the reader to the broad subject of gas turbines. Thus it is of use to both students of the subject and similarly to professionals as a desk reference in their daily lives.

Industrial Gas Turbines: Performance and Operability explains important aspects of gas turbine performance such as performance deterioration, service life and engine emissions. Traditionally, gas turbine performance has been taught from a design perspective with insufficient attention paid to the operational issues of a specific site. Operators are not always sufficiently familiar with engine performance issues to resolve operational problems and optimise performance. Industrial Gas Turbines: Performance and Operability discusses the key factors determining the performance of compressors, turbines, combustion and engine controls. An accompanying engine simulator CD illustrates gas turbine performance from the perspective of the operator, building on the concepts discussed in the text. The simulator is effectively a virtual engine and can be subjected to operating conditions that would be dangerous and damaging to an engine in real-life conditions. It also deals with issues of engine deterioration, emissions and turbine life. The combined use of text and simulators is designed to allow the reader to better understand and optimise gas turbine operation. Discusses the key factors in determining the perfomance of compressors, turbines, combustion and engine controls Explains important aspects of gas and turbine perfomance such as service life and engine emissions Accompanied by CD illustrating gas turbine performance, building on the concepts discussed in the text

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

"The use of gas turbines for generating electricity dates back to 1939. Today, gas turbines are one of the most widely-used power generating technologies. Gas turbines are a type of internal combustion (IC) engine in which burning of an air-fuel mixture produces hot gases that spin a turbine to produce power. It is the production of hot gas during fuel combustion, not the fuel itself that the gives gas turbines the name. Gas turbines can employ a range of fuels, including natural gas, fuel oils, and synthetic fuels. Combustion occurs continuously in gas turbines, as opposed to reciprocating IC engines, in which combustion occurs intermittently. Progress in Gas Turbine Performance is of valuable for design, analyst, materials and maintenance engineers. Also manufacturers, researchers and scientists will benefit from the suitable and precise information delivered in this book. There has been a remarkable difference in the research and development regarding gas turbine technology for transportation and power generation. While being considered a key technology for base-load operations for many years, modern stationary gas turbines are in fact facing the challenge to balance electricity from variable renewables with that from flexible conventional power plants. The book intends in fact to provide a restructured picture along with a perspective view of some of the issues that characterize gas turbine technology in the different applications. It admirably describes the fundamentals of gas turbine performance and whole engine design for those who have not yet encountered them, while providing an abundance of reference material for those who are more advanced. This is particularly valuable because another facet of change in our industry is that engineers are unlikely to continue their careers concentrating on only aero, or industrial and marine engines.

Widely used for power generation, gas turbine engines are susceptible to faults due to the harsh working environment. Most engine problems are preceded by a sharp change in measurement deviations compared to a baseline engine, but the trend data of these deviations over time are contaminated with noise and non-Gaussian outliers. Gas Turbine Diagnostics: Signal Processing and Fault Isolation presents signal processing algorithms to improve fault diagnosis in gas turbine engines, particularly jet engines. The algorithms focus on removing noise and outliers while keeping the key signal features that may indicate a fault. The book brings together recent methods in data filtering, trend shift detection, and fault isolation, including several novel approaches proposed by the author. Each method is demonstrated through numerical simulations that can be easily performed by the reader. Coverage includes: Filters for gas turbines with slow data availability Hybrid filters for engines equipped with faster data monitoring systems Nonlinear myriad filters for cases where monitoring of transient data can lead to better fault detection Innovative nonlinear filters for data cleaning developed using optimization methods An edge detector based on gradient and Laplacian calculations A process of automating fault isolation using a bank of Kalman filters, fuzzy logic systems, neural networks, and genetic fuzzy systems when an engine model is available An example of vibration-based diagnostics for turbine blades to complement the performance-based methods Using simple examples, the book describes new research tools to more effectively isolate faults in gas turbine engines. These algorithms may also be useful for condition and health monitoring in other systems where sharp changes in measurement data indicate the onset of a fault.

Gas Turbine Theory, 5th edition HIH Saravanamuttoo, GFC Rogers, H Cohen When the First Edition of this book was written fifty years ago, the gas turbine was just becoming established as a powerplant for military aircraft. It took another decade before the gas turbine was introduced to civil aircraft, and this market developed so rapidly that the ocean liner was rendered obsolete. Other markets like naval propulsion, pipeline compression and electrical power applications grew steadily. In recent years the gas turbine, in combination with the steam turbine, has played an ever-increasing role in power generation. Despite the rapid advances in both output and efficiency, the basic theory of the gas turbine has remained unchanged. The layout of this new edition is broadly similar to the original, but greatly expanded and updated, comprising an outline of the basic theory, aerodynamic design of individual components, and the prediction of off-design performance. Descriptions of engine developments and current markets make this book useful to both students and practising engineers. FEATURES: - completely updated to cover current industry requirements and applications - coverage of both aircraft and industrial gas turbines - includes detailed treatment of off-design performance - incorporates in-depth examples throughout - based on the authors' extensive teaching and professional experience Gas Turbine Theory is the classic course text on gas turbines, suitable for both undergraduate and graduate students of mechanical and aeronautical engineering. This new edition will also continue to be a valuable reference for practising gas turbine engineers. THE AUTHORS H.I.H. Saravanamuttoo, Professor Emeritus, Dept of Mechanical and Aerospace Engineering, Carleton University, Ottawa, Canada, has many years experience in the gas turbine industry on both sides of the Atlantic, and is a Past President of the Canadian Aeronautics and Space Institute. G.F.C. Rogers was, until retirement, Professor of Engineering Thermodynamics at the University of Bristol. He is author, with Y.R. Mayhew, of Engineering Thermodynamics Work and Heat Transfer, 4th edition. The late H. Cohen, was formerly University Lecturer and Director of Studies in Engineering at Queen's College, Cambridge.

The availability of fossil fuels required for power plants is reducing and their costs increasing rapidly. This gives rise to increase in the cost of generation of electricity. But electricity regulators have to control the price of electricity so that consumers are not stressed with high costs. In addition, environmental considerations are forcing power plants to reduce CO2 emissions. Under these circumstances, power plants are constantly under pressure to improve the efficiency of operating plants, and to reduce fuel consumption. In order to progress in this direction, it is important that power plants regularly audit their energy use in terms of the operating plant heat rate and auxiliary power consumption. Energy Audit of Thermal Power, Combined Cycle, and Cogeneration Plants attempts to refresh the fundamentals of the science and engineering of thermal power plants, and establishes its link with the real power plant performance data through case studies, and further developing techno-economics of the energy efficiency improvement measures. This book will rekindle interest in energy audits and analysis of the data for designing and implementation of energy conservation measures on a continuous basis.
