Coal Mill an overview ScienceDirect Topics

In coal milling for power stations, a ‘closed-loop’ process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the re-circulation loop is within the mill, but some mill types would have an external loop.

In 1914 the Board of Trade gave consent for the construction of a power station at Whitebirk (53°45'36"N 2°26'51"W) about 3 miles north-east of Blackburn town centre. Construction was delayed by the First World War and the power station was eventually built and was formally opened by Lord Derby on 22 October 1921. The generating plant comprised two 10 MW English Electric Company Limited turbo-alternators supplied with up to 240,000 lb/hr of steam (3.02 kg/s).

Coal-mill optimisation in coal-fired power stations aids

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.
