Bottom ash

Bottom ash

Coal bottom ash is a coarse, granular byproduct of coal combustion that is collected from the bottom of coal furnaces in power plants. When pulverized coal is burned in a dry bottom boiler, approximately 80 percent of the unburned material is captured from the chimney as fly ash. The remaining 20 percent is bottom ash, which is collected in a ...
