A development program on pressurized fluidized-bed combustion is being carried out in a bench-scale pilot plant capable of operating at 10-atm pressure. The concept involves burning fuels such as coal in a fluidized bed of particulate lime additive that reacts with the sulfur compounds formed during combustion to reduce air pollution. Nitrogen oxide emissions are also reduced at the combustion temperatures used, which are lower than those used in a conventional coal combustor. The CaSO/sub 4/ produced in the combustor is regenerated to CaO that is recycled to the combustor for removal of sulfur compounds. Information is presented on the effects of coal and additive particle size on SO/sub 2/ and NO emissions, one-step regeneration of sulfated limestone, laboratory-scale experiments on the reaction of calcium sulfide with calcium sulfate, volatile constituents in the effluent gas from coal combustion, properties of a dolomite bed of a range of particle sizes and shapes at minimum fluidization, and the status of separation of the combustion system and regeneration system.
