Effects of Mill Performance on Unburnt Carbon in Coal

While renewable energy has undergone wide and rapid deployment, coal is still expected to be the main source of fuel for producing base load power in the near future. This is because coal reserves are expected to last for the next century and its cost is still relatively cheap. However, the emissions from coal combustion are a major environmental concern.

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
