Coal Combustion Methods Ground Truth Trekkingpulverised coal advantages vs lump coal centralinovoipeu

Coal can be used in a wide variety of ways ranging from direct burning to produce heat and/or steam to newer methods of coal gasification and liquefaction including coal to liquids The following is a summary of coal combustion methods relevant to coal fired power plants or PCC= pulverised coal combustion AC= air cooled WC= water cooled Capture separation of CO2 A number of means exist to capture carbon dioxide from gas streams but they have not yet been optimised for the scale required in coal burning power plants
