Advantages and Disadvantages of Pulverized Coal Firing

Advantages and Disadvantages of Pulverized Coal Firing

Pulverized coal is used in modern thermal power plants. It is a powdered form of coal, coal that is grounded into a dustlike size. The pulverized coal is then conveyed to the furnace by way of a stream of hot air. An important purpose of pulverization is to expose a large surface area to oxygen, thus aiding in the burning process.

Pulverised Coal Combustion with higher efficiency CTCN

Pulverised Coal Combustion with higher efficiency CTCN

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.
