Coal Mill - an overview ScienceDirect Topics

Each plant is fired with sub-bituminous coal from the powder river basin PRB see Table 9.3 for coal properties and sized to generate 750 MW of net power. The flue gas temperature exiting the air heaters of all four boilers is 121 C 250 F and the boiler efficiency is 87.2% HHV .

Coal-fired power station - Wikipedia

In plants that burn pulverized coal, silos feed coal to pulverizers coal mills that take the larger 5 cm pieces, grind them to the consistency of talcum powder, sort them, and mix them with primary combustion air, which transports the coal to the boiler furnace and preheats the coal in order to drive off excess moisture content.

This is all controlled by the coal mill or pulveriser, and its associated feeder equipment. Operation of the coal mill can affect the ramp rate of the power station and its ability to handle rapid changes in output. For coal-fired power plants, the response time of the coal mills is critical for the overall reaction time to changing demand.

Pulverizer - Wikipedia

Similar to the ring and ball mill, the vertical spindle roller mill uses large "tires" to crush the coal. These mills are usually found in utility plants. coal is gravity-fed through a central feed pipe to the grinding table where it flows outwardly by centrifugal action and is ground between the rollers and table.
