Two thousand atmospheric fluidized bed (AFB) boilers are in use in the People's Republic of China. The major Chinese objective is the use of local fuels--oil shale, char from coal-gasification processes and lignite--all of which is of poor quality and can be burned most economically in AFB's. AFB use in the US would emphasize SO/sub 2/ removal in the combustion chamber to comply with air-pollution standards. While Chinese AFB's are simple, locally produced, US AFB's concentrate on sophisticated control systems to minimize reagent consumption in SO/sub 2/ capture. Various standard units and homemade AFB boilers in China are surveyed. Pictures of coal dumping, feeding, ash quenching, and control room are given. The Chinese procedure for startup is described in detail.
