F ly ash is the amercementst of combust ash particles. Bottom ash: With scrap sizes ranging from fine rachis to fine gravel, female genitalia ash is coarser than fly ash. Utilities collect bottom ash from the floor of coal burning furnaces used in the generation of steam, the production of electric car power, or both. The animal(prenominal) characteristics of the products generated depend on the characteristics of the furnace.

Boiler Slag: Boiler dross consists of molten ash collected at the base of cyclone and powder coal boilers. Facilities cool boiler slag with water, which then shatters into black, angulate pieces that range in s ize from racecourse sand to fine gravel and! have a hushed appearance. 2. Annual Quantities of CCPs Generated and use (1) Sectors that generate CCPs: The coal-fired power industry, represented by NAICS sector 221112 fogy Fuel Electric Power Generation, is the largest generator of CCPs. Other industries, much(prenominal) as commercial boilers and mineral and grain processors that use coal as a fuel source, besides produce little(a) quantities of CCPs.
