Pulverized Coal Combustion Definition Power Plant CCS

In a pulverized coal combustion process, the coal is ground to talcumpowder fineness, and injected through burners into the furnace with combustion air. The fine coal particles heat up rapidly, undergo pyrolysis and ignite. The bulk of the combustion air is then mixed into the flame to completely burn the coal char. The flue
