Thermal Power Plant ScienceDirect

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. Depending on speed pulverizers are classified as low-speed medium-speed and high-speed mills.
