Coal Mill - an overview | ScienceDirect TopicsTraduire cette page

Pulverized fuel ash is formed during the process of combustion of pulverised coal in the furnace of the power station's boiler. The coal is ground to powder-coal in coal mills, before being blown by compressed air into the furnace and burned at temperatures ranging between 1300 and 1600 °C, depending on the type of boiler in question.
