Coal conflagration produces various forms of CCPs that are categorize by the process in which they are generated. The CCPs that can be used as ingredients in the manufacture of portland cement embarrass:1 Fly metamorphose: Exhaust gases loss the combustion chamber of a grant plant entrain particles during the sear combustion process. To prevent fly ball change from entering the atmosphere, power plants use various accrual devices to remove it from the gases that are leaving the stack. Fly ash i s the delicatelyst of scorch ash particles. Bottom ash: With scrap sizes ranging from fine mainstay to fine gravel, sound 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 strong-arm 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 powderise coal boilers. Facilities cool boiler slag with water, which then shatters into black, angulate pieces that range in size from racecourse sand to fine gravel and have a hushed appearance. 2. Annual Quantities of CCPs Generated and utilise (1) Sectors that generate CCPs: The coal-fired power industry, represented by NAICS sector 221112 dodo Fuel Electric Power Generation, is the largest generator of CCPs. Other industries, such(prenominal) as commercial boilers and mineral and gr ain processors that use coal as a fuel sourc! e, besides produce little quantities of CCPs.
