The decrease in coal utilization rate resulted from the increased higher heating value (HHV) of the coal. The reduced-moisture coal also had improved grindability, thus mill power decreased by almost 10%. This allowed the unit to be operated with six mills in service, instead of the customary seven or eight.

Ensure optimum arrangement of the mill throat and the coal flow path to improve mill performance. * *Close tolerances. Pulverized coal mills with throats that are too wide will have corresponding low throat velocity in the mill grinding zone that contributes to excessive coal rejects and fires. This is an example of an oversized mill throat.
