from coal combustion are primarily sulfur dioxide (SO 2), with a much lower quantity of sulfur trioxide (SO 3) and gaseous sulfates. These compounds form as the organic and pyritic sulfur in the coal are oxidized during the combustion process. On average, about 95 percent of the sulfur present in bituminous coal will be emitted as gaseous SO x

coal requiring 20% more pounds of coal could easily exceed the burning capacity of the stoker such that output of the steam generator may be reduced. In short, lower Btu coal will increase the pounds of coal to be handled and when the variations are large enough we can expect a reduction in boiler capacity. Higher Btu coal seldom gives any pro-
