Download or read book Combustor Technology for Broadened Properties Fuels written by W. J. Dodds and published by . This book was released on 1984 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to increase the availability and reduce the cost of future fuels for aircraft gas turbine engines, it may be necessary to broaden fuel specifications. Anticipated changes in fuel properties, and the effects of these changes on combustion system performance, operating characteristics, durability, and emissions are briefly reviewed, and results to date of a program being conducted to develop and demonstrate combustor technology required to utilize broadened-properties fuels in current and next-generation engines are described. Combustion system design considerations and tradeoffs for burning broadened-properties fuels are discussed, and test experience with several applicable combustor design modifications to the G.E. CF6-80A combustion system is reviewed. Modifications have been demonstrated to improve liner cooling and reduce smoke in the conventional annular combustor, thereby reducing effects of variations in fuel hydrogen content. Advanced staged and variable geometry combustor concepts for burning broadened-properties fuels have also been demonstrated.

This book was released on 2018-07-23 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental evaluation of two advanced technology combustor concepts was conducted to evolve and assess their capability for operation on broadened properties fuels. The concepts were based on the results of Phase 1 of the Broad Specification Fuel Combustor Technology Program which indicated that combustors with variable geometry or staged combustion zones had a flexibility of operation that could facilitate operation on these fuels. Emphasis in defining these concepts included the use of single pipe as opposed to duplex or staged fuels systems to avoid the risk of coking associated with the reduction in thermal stability expected in broadened properties fuels. The first concept was a variable geometry combustor in which the airflow into the primary zone could be altered through valves on the front while the second was an outgrowth of the staged Vorbix combustor, evolved under the NASA/P&W ECCP and EEE programs incorporating simplified fuel and air introduction. The results of the investigation, which involved the use of Experimental Referee Broad Specification (ERBS) fuel, indicated that in the form initially conceived, both of these combustor concepts were deficient in performance relative to many of the program goals for performance emissions. However, variations of both combustors were evaluated that incorporated features to simulate conceptual enhancement to demonstrate the long range potential of the combustor. In both cases, significant improvements relative to the program goals were observed. Lohmann, R. P. and Jeroszko, R. A. and Kennedy, J. B.

This book was released on 2012-12-13 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the length of time it has been around, its importance, and vast amounts of research, combustion is still far from being completely understood. Environmental, cost, and fuel consumption issues add further complexity, particularly in the process and power generation industries. Dedicated to advancing the art and science of industrial combustion, The John Zink Hamworthy Combustion Handbook, Second Edition: Volume One – Fundamentals gives you a strong understanding of the basic concepts and theory. Under the leadership of Charles E. Baukal, Jr., top combustion engineers and technologists from John Zink Hamworthy Combustion examine the interdisciplinary fundamentals—including chemistry, fluid flow, and heat transfer—as they apply to industrial combustion. What’s New in This Edition Expanded to three volumes, with Volume One focusing on fundamentals Extensive updates and revisions throughout Updated information on HPI/CPI industries, including alternative fuels, advanced refining techniques, emissions standards, and new technologies Expanded coverage of the physical and chemical principles of combustion New practices in coal combustion, such as gasification The latest developments in cold-flow modeling, CFD-based modeling, and mathematical modeling Greater coverage of pollution emissions and NOx reduction techniques New material on combustion diagnostics, testing, and training More property data useful for the design and operation of combustion equipment Coverage of technologies such as metallurgy, refractories, blowers, and vapor control equipment Now expanded to three volumes, the second edition of the bestselling The John Zink Combustion Handbook continues to provide the comprehensive coverage, up-to-date information, and visual presentation that made the first edition an industry standard.

Available in PDF, EPUB and Kindle. Book excerpt: Combustion Technology: Some Modern Developments reviews modern developments in combustion technology, with emphasis on furnace flames. Topics covered range from equilibria and chemical kinetics in flames to corrosion and deposits in combustion systems, along with combustion aerodynamics and noise. Heat transfer from non-luminous flames in furnaces is also investigated. Comprised of 15 chapters, this book begins with an overview of some aspects of the chemistry of flames, followed by a discussion on the problem of corrosion and deposits. Subsequent chapters focus on aerodynamics and heat transfer in combustors, together with combustion noise and the application of aerodynamic principles to flame stabilization in high-speed flow; radiative heat transfer in combustion chambers; electrical properties of flames; flame-field interactions and their practical applications; generation of electricity by magnetohydrodynamic methods; and practical aspects of magnetohydrodynamic power generation. The book also assesses the influence of stirred reactor theory on design principles for high-performance combustion chambers and concludes with a summary of developments in the design and utilization of oil burners. This monograph should be of interest to engineers and combustion technologists.
