Because of the higher moisture content, the primary air inlet temperature must be increased in order to dry the coal for proper transport and flame stability. The coal throughput to the mill must also be increased in order to maintain the same megawatt output from the unit. These two factors cause the mills to often be the source of an overall

Boiler Performance and Mill Outlet Temperature

Boiler Performance and Mill Outlet Temperature

Two major parameters which decide the mill capacity and performance are the hardness of coal and the total moisture level in coal. The mill outlet temperature of coalair mixture is maintained between 65 to 90 degree centigrade in the case of low and medium volatile coal. In the case of high volatile coal while the lower limit generally remains as 65 degree centigrade, the upper limit is
