Biomass Gasification Design Handbook

This handbook explains how biomass can be converted to a gas in a downdraft gasifier and gives details for designing, testing, operating, and manufacturing gasifiers and gasifier systems, primarily for shaft power generation up to 200 kW. t is intended to help convert gasification from a practical art into a field of en­gineered design. Although the handbook focuses on downdraft gasification as the only method suitable for small-scale power systems, it also gives extensive detail on biomass fuels, gas testing and cleanup in­strumentation, and safety considerations that will be of use to all those who work with gasifiers at whatever scale. The combustion of biomass in wood stoves and in­dustrial boilers has increased dramatically in some areas, and forest, agricultural, and paper wastes are being used extensively for fuels by some industries. However, more extensive biomass use still waits for the application of improved conversion methods, such as gasification, that match biomass energy to processes currently requiring liquid and gaseous fuels. Examples of such processes include glass, lime, and brick manufacture; power generation; and transportation.CONTENTS1.0 Introduction and Guide to the Literature and Research2.0 History, Current Directions, and Future Development3.0 Gasifier Fuels4.0 Principles of Gasification 5.0 Gasifier Designs6.0 Gasifier Fabrication and Manufacture7.0 Gas Testing8.0 Gas Cleaning and Conditioning 9.0 Gasifier Systems10.0 Instrumentation and Control11.0 Engine Adaptation and Operation12.0 Safety and Environmental Considerations 13.0 Decision MakingReferencesAppendixThe ultimate guide to researching and potentially building a biomass downdraft gasifier engine system.

This book addresses the science and technology of the gasification process and the production of electricity, synthetic fuels and other useful chemicals. Pursuing a holistic approach, it covers the fundamentals of gasification and its various applications. In addition to discussing recent advances and outlining future directions, it covers advanced topics such as underground coal gasification and chemical looping combustion, and describes the state-of-the-art experimental techniques, modeling and numerical simulations, environmentally friendly approaches, and technological challenges involved. Written in an easy-to-understand format with a comprehensive glossary and bibliography, the book offers an ideal reference guide to coal and biomass gasification for beginners, engineers and researchers involved in designing or operating gasification plants.
