Coal Pulverizers - an overview ScienceDirect Topics

In Appendix 6A we show a calculation taken from Musto (1978) for the primary and secondary air required for coal pulverizer with 4.5 metric ton per hour (10,000 lb/h) coal feed rate at initial moisture of 15 percent which is required to be ground and dried to 2% with a 200 HP mill. In order to estimate the actual primary and secondary air, one has to make some estimation of the evaporation rate, the amount of
