Features: This book is written to meet the rapidly developing needs of large-scale circulating fluidized bed boilers. It introduces the gas-solid flow characteristics, heat transfer characteristics, combustion process and pollution control characteristics, start-up and operation characteristics, and operational optimization experiments of large circulating fluidized bed boilers targeting 220–1025 t/h circulating fluidized bed boilers. It focuses on the structure and operational characteristics of the main body and auxiliary equipment of large circulating fluidized bed boilers, such as the furnace, separator, return system, air distribution system, rear steam-water heat transfer surfaces, external heat exchangers, air preheaters, ignition equipment, slag coolers, coal crushing equipment, limestone and fly ash conveying equipment. The book also discusses topics such as boiler expansion and sealing structures, wear-resistant design for metal heat transfer surfaces and refractory materials, anti-clogging design for air distributors and pressure measurement pipes, boiler forced draft systems, and the layout of superheaters and reheaters. This book can serve as a learning textbook and reference for technicians and managers engaged in research, design, installation, commissioning, and operation of large circulating fluidized bed boilers, as well as a reference for faculty and students of relevant majors in colleges and universities.
