摘要

Combustion tests were performed using a Cleaver-Brooks 350 hp fire-tube boiler-furnace to determine the efficiency of sulfur dioxide removal using soda ash and micronized additives. A high sulfur, 4.7% Ohio bituminous coal, ground to 92% through 200 mesh, was mixed with medium weight No. 4 oil and water to form the emulsions. Soda ash and micronized dolomite were added to the emulsion for SO sub 2 removal. An emulsion, without additives, was first tested and a thermal efficiency of 88% was obtained. The best SO sub 2 removal was with soda ash with from 82% to 96% removal. There were problems with ash deposition and slagging in the second pass. Fuel preparation problems were encountered with high particle content micronized dolomite emulsions. The successful dolomite fuels had poor SO sub 2 removal results. The long term testing on a coal/oil/water emulsion without any additives has begun and no major problems have been encountered. (ERA citation 07:006718)
