the combustion of crushed coal and air in boiler occurs

1.1 Bituminous And Subbituminous Coal Combustion categorized as PC-fired systems even though the coal is crushed to a maximum size of about 4-mesh. The coal is fed tangentially, with primary air, into a horizonal cylindrical furnace. Coal ash may either settle out in the boiler (bottom ash) or entrained in the flue gas (fly ash).

Coal-Fired Boiler an overview ScienceDirect Topics

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).get price
