Understanding Pulverized Coal Injection in Blast Furnace …

The moisture content of coal leaving the mill is to be two thirds of the equilibrium moisture level. Equilibrium moisture of the coal varies with its rank, maceral composition, and ash content. It is important to ensure that the coal is ground to the desired fineness with minimum wear on the pulverizer parts and with least power consumption in order to lower the operating costs.
