    Pulverised Coal Combustion with higher efficiency ...

    Producing electricity in coal power plants can take place in a number of ways with varying degrees of efficiency. In conventional coalfired plants coal is first pulverised into a fine powder and then combusted at temperatures of between 1300 and 1700 o C. This process heats water in tubes in the boiler so that it becomes steam at a pressure of around 180 bar and a temperature of 540 o C.

    Why Pulverized Coal is Used in a Power Plant

     ·  · Modern boilers powder the coal to a very fine dust so that while burning, it is almost like a fluid stream. The size of the coal particles is in the range of 75 microns. This means every particle comes into contact with the air. The loss due to unburned carbon is only in the range of % or less making the boilers very efficient. The pulverizer does the powdering or the pulverizing ...
