Design, construction and test program for a 300,000 lbs/hr steam generating capacity multicell fluidized-bed boiler (MFB), as a pollution-free method of burning high-sulfur, or highly corrosive coals, is being carried out. The concept involves burning fuels such as coal, in a fluidized-bed of limestone particles that react with the sulfur compounds formed during combustion to reduce pollution. Nitrogen oxide emissions are also reduced at the lower combustion temperatures. The CaSO/sub 4/ produced in the furnace is discharged with the ash or regenerated to CaO for reuse in the fluidized-bed. Information is presented on continued evaluation of alternate coal feed needles, testing of static rock layer as protection for the air supply grid, continued coal feed eductor tests, and gas sample traverses at the Alexandria laboratory; installation of test instrumentation and modifications to the MFB at Rivesville; supporting engineering and design efforts at New York office; and subcontract activities.
