This time, however, is dependent on various factors. The heart of a pulverized coalfired boiler is the pulverizer, also known as the mill. Depending on speed pulverizers are classified as lowspeed, mediumspeed, and highspeed mills. Pulverized coal burners may be located on the front or opposed walls or in the corners of the furnace.
The reheating furnace consists of a heating furnace body, a cooling system, a combustion system, an inlet and outlet, a smoke exhaust system, a preheating recovery system, and an automatic control system. Usually, the fuel of the furnace is gaseous fuel, natural gas, heavy oil or pulverized coal, some burning lump coal, etc.
