Fineness is an indicator of the quality of the pulverizer action. Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. The mill wear and the power consumption are increased if the 70% ...

A forced draft fan motor current (FFC) was used during boiler combustion to regulate the air flow rate entering the furnace. The results show that the FFC and coal flow change with the power output. However, the coal flow exhibits larger fluctuations than the FFC, indicating that the air/coal ratio is out of balance at certain times.
