Title: Commercial-sector coal/oil-slurry demonstration program. Final report. [Coal-oil-water ratios: 44-44-12; 42-42-16]

Technical Report ·
OSTI ID:5060112

This report represents work accomplished on the combustion properties of coal-No. 4 oil-water (COW) emulsions to which alkali absorbents for sulfur dioxide removal have been added. The fuels tested contained the following ratios of coal-oil-water; 44-44-12 and 42-42-16. The stoichiometric percentage of additives, based on the total sulfur in the fuel, used in the combustion tests was 100%. Using the sulfur dioxide absorbents, up to 86% of the SO/sub 2/ in the stack gas was removed. The thermal efficiencies of the emulsions were approximately the same as with oil, 89%. Ash deposition was not found to be a problem when burning COW emulsions without alkaline additives. Deposit formation was greatly increased with the addition of alkali additives. The feasibility of using a baghouse for particulate removal was also studied. The efficiency of the baghouse using a 44-44-12 emulsion with and without soda ash was determined. Collection efficiency was 99.8% and 99.3% respectively. The fly ash was easily cleaned from the baghouse filters.
