ABSTRACT:
A method is disclosed for burning a pulverized carbonaceous material containing sulfur and ash. According to this method, a slurry is formed containing the carbonaceous material, water, a reagent adapted to react during combustion with the sulfur in the material and a cementing agent adapted to reduce particulate emissions during combustion. The slurry is burned in a first stage with less than 100% theoretical air and preferably at a temperature below about 1100.degree. C. The products of combustion from the first stage are removed to a second stage and burned with additional air.
