Development program on pressurized fluidized-bed combustion. Quarterly report, October--December 1975
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: hot testing of the new bench-scale regeneration system, TGA experiments on sulfation and regeneration rates of supported additives and on cyclic sulfation regeneration experiments, petrographic change occurring during half-calcination of dolomite, laboratory-scale experiments on the reaction of calcium sulfide with calcium sulfate, coal combustion reactions, and quality of fluidization and minimum fluidization velocity studies.
