Coking coal must be low in sulfur and requires more thorough cleaning than coal used in power plants, which makes the coal more expensive. In 2021, the average delivered price of coking coal to coke producers was about 122 per short ton—about times higher than the average price of coal delivered to the electric power sector.

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% ...

Coal mills consume a huge amount of station service electricity power of a coalfired power plant. Meanwhile, the operation of coal mills also has a large influence on boiler combustion. Among all the operating factors, the electricity current intensity of coal mills reflects the electricity power consumption as well as operating status of coal mills. If the electricity current intensity of ...
