Furnace Bottom Ash (FBA) forms from the molten material that clings to the boiler tubes and falls into the bottom of the furnace during the combustion process at coal-fired power stations. This granular product is extracted wet from UK power stations, graded and sold as lightweight aggregate for use in concrete blocks etc.

Bottom ash and a component known as fly ash consist of coal components which did not combust during the burning phase. Fly ash is light enough that it is carried up the flue with the flue gases, and ideally trapped in filters before reaching the environment. Bottom ash forms clinkers on the wall of the furnace, with the clinkers eventually falling to the bottom of the furnace.

How Heavy Is Furnace 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 water-filled hopper at the bottom of the furnace
