Pulverised Coal Combustion with higher efficienc

2019-10-10 · Producing electricity in coal power plants can take place in a number of ways with varying degrees of 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. > Get A Quote >
