Coal desulfurization during the combustion of coal/oil/water emulsions: an economic alternative liquid fuel. Final quarterly report, September 26-December 31, 1980
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% western Kentucky coal, pulverized to 78% through 200 mesh was mixed with medium weight No. 4 oil and water to form the emulsions. Soda ash and micronized limestone and hydrated lime were added to the emulsion for SO/sub 2/ removal. Baseline combustion tests were first conducted on emulsions without additives. Thermal efficiencies of over 88% were obtained. The best SO/sub 2/ removal was with soda ash, with 80% and 78% removal. There were problems with ash deposition in pass 2 during these tests. Fuel preparation problems were encountered with high particle content micronized limestone and hydrated lime emulsions. The successful fuels had poor SO/sub 2/ removal results.
