Pulverised Coal - an overview ScienceDirect Topics

The finer the grinding of coal, the more efficient its combustion. The total time required from entry of a coal particle to a furnace to combustion of the particle is very short. This time, however, is dependent on various factors. The heart of a pulverized coal-fired boiler is the pulverizer, also known as the mill.
