A pulverized coalfired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal ... The raw coal is then fed into the pulverizer along with air heated to about 650 °F (340 °C) from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows out the usable fine coal ...
