FLUIDIZED BED BOILER AND METHOD OF OPERATING SAME UTILIZING PRECALCINATION OF ACCEPTORS

摘要

FLUIDIZED BED BOILER AND METHOD OF OPERATING SAME UTILIZING PRECALCINATION OF ACCEPTORS A fluidized bed boiler, and a method of operating same in which air is passed through a grate to fluidize a bed of particulate material containing fossil fuel disposed on the grate. A raw acceptor for the sulfur produced as a result of the combustion of the fuel is introduced into the housing and confined within an area of the housing isolated from the bed of particulate material. The area containing the acceptor is maintained at conditions optimal for calcining the acceptor, after which the latter is introduced into the fluidized bed.
