==================================================================== 1. translation of CCPs

Coal burning products (CCPs) are formed during blacken-burning processes in originator plants and industrial boilers. Coal combustion 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 modify: Exhaust gases loss the combustion chamber of a provide plant entrain particles during the coal combustion process. To prevent fly change from entering the atmosphere, power plants use various collection devices to remove it from the gases that are leaving the stack. Fly ash is the finest of coal ash particles. Bottom ash: With scrap sizes ranging from fine sand to fine gravel, bottom 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 physical 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 pulverized coal boilers. Facilities cool boiler slag with water, which then shatters into black, angular pieces that range in size from racecourse sand to fine gravel and have a hushed appearance. 2. Annual Quantities of CCPs Generated and Used (1) Sectors that generate CCPs: The coal-fired power industry, represented by NAICS sector 221112 Fossil Fuel Electric Power Generation, is the largest generator of CCPs. Other industries, such as commercial boilers and mineral and grain processors that use coal as a fuel source, besides produce small quantities of CCPs. (2) Quantities and...If you want to get a rich essay, order it on our website: Ordercustompaper.com
