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.
PROFESSIONAL CEMENT PLANT OPTIMIZATION, …
Due to ever increasing fuel costs the target was to change the plants operation from import coal with 25 % volatiles to local lignite coal with up to 40 % volatile matters and a moisture content of up to 20 %. For this reason the coal mill had to be modified form cooler middle air to pre-heater exhaust gas operation.
