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% ...

Inside the power station, the coal is pulverised to a fine powder in giant grinding mills. This is because pulverised coal burns quickly, like gas. The pulverised coal is transported to the boiler furnace with air where it burns. Boilers, as high as a 35storey office block, are the rectangular blocks that give power stations their distinctive ...

1. Introduction. The term Flue Gas Desulphurisation (FGD) system has traditionally referred to wet scrubbers that remove SO 2 emissions from large electric utility boilers. The FGD systems emerged in the industrial field of the coalfired power plants and on some industrial processes in the early 1970s in United States (US) and Japan, and expanded rapidly in the 1980s [1] in Europe.
