Coal Mill - an overview | ScienceDirect Topics
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. Coal contains 10 to 15% non-combustible mineral material. Most of this material melts in the furnace.
