Pulverised Coal Combustion with higher efficiency
In conventional coal fired 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.
