Coal-Fired Industrial Boiler Inspection Guide - EPA

s The particulate emission rate is a function of the coal ash content and the firing method. Pulverized-coal-fired boilers emit between 70 and 85 percent of the ash in the coal as fly ash. In contrast, a stoker-fired boiler emits only 3.0 to 50 percent of the coal ash with the flue gas.
