Combustion and Heat Transfer in Gas Turbine Systems is a compilation of papers from the Proceedings of an International Propulsion Symposium held at the College of Aeronautics, Cranfield in April 1969. This compilation deals with research done by academic and scientific institutions and of industrial organizations, with some research papers covering atomization, fuels, and high-temperature materials. One paper describes the combustion system of the Concorde engine used in commercial flights, temperature of metal parts, and some design modifications to increase the mechanical life of the combustion system. Another paper discusses the evolution of the RB 162 combustion system that is used in the vertical takeoff and landing aircrafts. The RB 162 has many design features of the earlier single reversal chamber and differs in only one or two points. The book then notes the necessity of a plenum chamber burning to further development of supersonic engines and flight. One paper also proposes an alternative theory to the traditional ignition theory of altitude relighting such as those developed by Lewis and von Elbe. Another paper reposts on some observations made of the atomizing characteristics of air-blast atomizers and proposes simple changes to improve the performance of the atomizer by prefilming and allowing air to both sides of the fuel. This compilation will prove very helpful for aeronautical engineers, aviation designers, physicists, students of engineering, and readers who are interested in the design and development of jet engines and supersonic aircrafts.

Regenerative gas turbines are attractive alternatives to diesel engines and spark ignition engines for automobiles and to diesel engines and combined-cycle en gines for power generation. Theory indicates regenerative gas turbines should achieve higher thermal efficiencies than those of diesel engines and combined cycle engines. Further, regenerative gas turbines are potentially lower in cost, require less maintenance, require less space, and pollute less than competitive systems. Regenerators can be used for exhaust-gas heat exchange or for intercooling in gas-turbine systems. As an exhaust-gas heat exchanger, a regenerator recovers heat from the exhaust and uses it to preheat the compressed air before the compressed air enters the combustor. Preheating of the compressed air permits a small heat input to the combustor for a given power output of the engine. As an intercooler, a regenerator cools the gas between compressor stages. Less work is required to compress cool gas than is required to compress warm gas. Therefore, a regenerator intercooler can reduce the required work input to the compressor. Thus, regenerators can be used to increase the thermal efficiencies and power outputs of gas turbines. the backbones of high-performance re High-performance regenerators are generative gas turbines. In the past, lack of understanding of regenerator per formance has led to sub-optimal engine designs. Now this book gives com prehensive regenerator information. With this book, the designer can design regenerators that will yield gas turbines with maximum thermal efficiencies.

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

Gas turbine engines will still represent a key technology in the next 20-year energy scenarios, either in stand-alone applications or in combination with other power generation equipment. This book intends in fact to provide an updated picture as well as a perspective vision of some of the major improvements that characterize the gas turbine technology in different applications, from marine and aircraft propulsion to industrial and stationary power generation. Therefore, the target audience for it involves design, analyst, materials and maintenance engineers. Also manufacturers, researchers and scientists will benefit from the timely and accurate information provided in this volume. The book is organized into five main sections including 21 chapters overall: (I) Aero and Marine Gas Turbines, (II) Gas Turbine Systems, (III) Heat Transfer, (IV) Combustion and (V) Materials and Fabrication.

Cranfield International Symposium Series, Volume 10: Combustion in Advanced Gas Turbine Systems covers the proceedings of an International Propulsion Symposium, held at the College of Aeronautics in Cranfield in April 1967. The book focuses on the processes, methodologies, reactions, and transformations involved in chemical combustion. The selection first takes a look at the design considerations in advanced gas turbine combustion chambers, combustion in industrial gas turbines, and combustion development on the Rolls-Royce Spey engine. Discussions focus on mechanical condition, carbon-formation and exhaust smoke, system requirements, fuel oil ash deposition and corrosion, combustion-system design, performance requirements, types of primary zone, fuel injection, and combustion chamber types. The text then examines subsonic flow flameholder studies using a low pressure simulation technique; stabilization of hydrogen diffusion flames by flame-holders in supersonic flow at low stagnation temperatures; and augmentation systems for turbofan engines. The book takes a look at a consideration of the possible use of refractory ceramic materials for advanced combustion chamber design; cooling of flame tubes by steam injection; and combustion problems in the massive steam injection gas turbine. The selection is a valuable source of information for researchers interested in the process of combustion in advanced gas turbine systems.
