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 ...

Coal mills or pulverizers play a very essential part in the coalfired power production system. Coal mills grind the coal into fine powder, and the primary air entering the mill dries and drives the coal into the power plant furnace for combustion. Mills can be a bottleneck for the power generation process.
