This book provides extensive information on high-temperature H2S removal for integrated gasification combined cycle (IGCC) coarse gas, together with briefly introductions to the concept of clean coal technology, and to the mechanism and kinetics of hot coal gas desulfurizers. Readers will gain a comprehensive understanding of available control methods for high-temperature H2S removal in IGCC coarse gas and how the technology has been adopted by industry. As such, the book offers a unique resource for researchers and engineers in the fields of energy science and technology, environmental science and technology, and chemical engineering.

Power Generation from Solid Fuels introduces the different technologies to produce heat and power from solid fossil (hard coal, brown coal) and renewable (biomass, waste) fuels, such as combustion and gasification, steam power plants and combined cycles etc. The book discusses technologies with regard to their efficiency, emissions, operational behavior, residues and costs. Besides proven state of the art processes, the focus is on the potential of new technologies currently under development or demonstration. The main motivation of the book is to explain the technical possibilities for reducing CO2 emissions from solid fuels. The strategies which are treated are: more efficient power and heat generation technologies, processes for the utilisation of renewable solid fuels, such as biomass and waste, and technologies for carbon capture and storage. Power Generation from Solid Fuels provides, both to academia and industry, a concise treatment of industrial combustion of all types of solid, hopefully inspiring the next generation of engineers and scientists.

The more than 90 refereed papers in this volume continue a series of biannual benchmarks for technologies that maximize energy conversion while minimizing undesirable emissions. Covering the entire range of industrial and transport combustion as well as strategies for energy research and development, these state-of-the-art will be indispensable to mechanical and chemical engineers in academia and industry and technical personnel in military, energy and environmental government agencies. The topics covered in this book include wood, oil, gas and coal combustion, combustion of alternative fuels, co-combustion and co-gasification, catalytic combustion, NO, SO, soot fundamentals, advanced diagnostics, burners, fluidized bed combustion, incineration, engines, advanced cycles, gas clean-up, control strategy and clean combustion in process industries.

The primary objective of the Phase I ERDA High-Temperature Turbine Technology (HTTT) Program was to provide a ''Program and System Definition'' of the three-phase program which would culminate in the testing of a Technology Readiness Vehicle (TRV) at the end of a six-year period. The TRV is designed for use in a combined cycle using coal-derived fuels at a firing temperature of 2600°F; growth capability to 3000°F is projected. The Phase I results reported are based on a 2600°F gas turbine burning coal-derived fuels. The following major areas are covered: overall plant design descriptions; systems design descriptions; turbine subsystem design; combustor design; phase II proposed program; and phase III proposed program. Details regarding final results of each of these areas are presented. It is concluded that the water-cooled gas turbine in combined cycle has been shown to be capable of extremely attractive levels of performance, both in terms of efficiency and specific output. Coupled with the ability to tolerate a wide range of coal-derived fuels with minimum fuel treatment, an extremely attractive system is presented for the generation of electric power. Future technology development of the high-firing-temperature water-cooled gas turbine is expected to result in the commercial introduction of this concept in combined cycles by the late 1980's or early 1990's.

In recent years, interest in the technology of gas cleaning has grown, driven partly by environmental legislation, but also by demands for increases in process efficiency and intensity - notable for power generation and waste incineration. This book, which leads on from our successful Gas Cleaning at High Temperatures, describes the present state of the art and its industrial applications.
