Abstract
A fluidized-bed combustion pilot plant and a fluidized-bed regenerator, both capable of operating at 10-atm pressure, have been tested and operated. In combustion of coal at 9-atm pressure and 1550F (843C), high (>90%) retention of sulfur in the fluidized bed of dolomite has been obtained with continous addition of fresh dolomite at a Ca/S ratio of 3. The NO level in the flue gas has been low, <150 ppm. Two favored methods for regenerating the sulfated dolomite have been studies: a one-step reductive decomposition of the CaSO4 to CaS at about 1700F followed by reaction of CaS with H2O/CO2 to release H2S.
