Results of a bench-scale and laboratory-scale experimental investigation of the feasibility of applying fluidized-bed combustion (FBC) of coal to power generation are given. The FBC concept would combust coal at elevated pressure (to 10 atm) in a fluidized bed of dolomite, which reacts with the SO2 formed during combustion. The partially sulfated dolomite is then regenerated using one of the two alternative techniques: a one-step reductive decomposition technique (converting CaSO4 to CaO and SO2); or a two-step technique involving the reduction of CaSO4 to CaS, followed by reaction of the CaS with H2O and CO2 to form CaCO3 and H2S. Results of the pressurized FBC tests indicate favorable air pollutant emission control, with 90-95% reduction in SO2 emission, and with NO levels of about 150 ppm, well below EPA's New Source Performance Standards for large coal boilers. Initial sorbent regeneration studies showed significant deactivation and decrepitation of the dolomite; further investigation is necessary in the area of regeneration.
