Answer 1 of 4 Electricity from coal is generated when coal is burned. Thus heat energy is converted to electricity. Now there are various processes by which coal energy is converted to electricity.Firstly a machine called pulverizer grinds the coal into fragments and powder. Then by mixing it with hot air the coal burns efficiently. Then it is moved to a furnace.

Coal pulverizers typically operate under challenging conditions to perform the fundamental and important task of crushing the fuel to a uniform optimum size for proper combustion in coal-powered power plants. Pulverizers, are critical to the operation of any coal-fired boiler. The pulverizers, as the name implies, crush coal into a fine powder ...
Aug 13, 2009 The history of pulverization date back as early as 1824 and was envisaged by Carnot in a coal fired engine. In 1890 Diesel made use of pulverized coal in his diesel engine. The pulverized coal firing was first developed in cement industry which then migrated to power and process industries. Pulverizing coal in boiler is an important factor the overall cycle efficiency.
