Coal mills are used in coal fired power plants to grind crushed coal lumps with several cm diameters to very fine powder in the order of 50– 100 μ m diameter. A further task of coal mills is to dry the coal particles avoiding wet coal conditions during combustion. This is achieved by hot air passing through the mill which evaporates the coal moisture. The air dries the coal and also carries ...

Pulverized coal firing ensures complete combustion of coal, thus ensuring higher efficiency of steam generators. It is predominantly adopted in large coal-fired utility boilers. The finer the grinding of coal, the more efficient its combustion. 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 ...
