The radial and circumferential movement of the coal carries the pulverized coal up over the edge of the bowl into the path of the hot air stream. The hot air supplied to the pulverizer has two primary functions: 1. The hot air dries the coal. 2. The hot air is used for transportation of the recirculating coal within the mill and also for

at the entrance to the coal nozzle, redistributes the coal particles entering the pulverized coal burner to break up the coal "rope" that develops in any typical coal piping system. Coal ropes can contribute to high CO emissions and high flyash UBC by presenting too dense a coal stream to the combustion field.

The BTM is a low-speed mill that primarily grinds coal by impact and attrition. The VRM is a medium- speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed
