The coal is pulverised to fineness such that 70-80% passes through a 200 Mesh sieve. Normally low speed ball mills or medium speed vertical spindle mills are employed in thermal power plant for this purpose. The milling system is an important part of the auxiliary equipment of a coal-fired power plant.
The efficiency of pulverized fuel firing system mostly depends upon the size of the powder. The fineness of the coal should be such as 70% of it would pass through a 200 mesh sieve and 98% through 50 mesh sieve. Many modern thermal power plants use pulverized fuel system when the available coal is cheap and is not suitable for stroke firing.
