In addition, the fineness of the coal directly reduces losses by decreasing the amount of unburned carbon in fly and bottom ash. Flow in the classifier systems of an actual PP is complex and is not yet fully understood. Additionally, it is difficult to obtain experimental data for coal samples and measure mass flows rates at isokinetic conditions.
