Coal Pulverising in Boilers

Today all boiler designers opt to use ball or vertical spindle mill for coal other than lignite. While selecting the type of mill boiler designers must clearly understand the coal characteristics, the overall system being used, and the maintenance requirement. It is always seen that if the advantage of the mill alone is considered, then the overall boiler economics can prove to be different ...
