Realtime coal classification in thermal power plants

The coal mills are fed from different bunkers which may not be synchronized in terms of coal grades (Xia, Peng, Zhang, Yang, Chen, 2011). Secondly, coal change in a mill or a boiler is a gradual process which may take several hours (Tuttle, Blackburn, Powell, 2020) to transition from one coal to another. Both unintentional and planned ...

20. 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% ...
