Coal Mill an overview ScienceDirect Topics

The raw (coal) feed enters the mill through a central delivery pipe and falls under gravity onto the Grinding Table; The raw fuel gas is cleaned extensively and combusted in a coal boiler via specially designed low-CV gas burners. An advantage of this concept is that there is no contamination of the fuel gas as it enters the coal-fired boiler.
