Coal and petcoke are pulverized to about raw meal fineness in grinding plants using equipment similar to the rawmaterial grinding plants. The fineness of the pulverized fuel is important: too fine fuel can cause excessively high flame temperatures; too coarse fuel can cause poor combustion. Low volatility solid fuel will need finer grinding.
