  • Coal powder processing Grinding Mill

    The pulverized coal in the tower is fed into the pulverized coal burner by the feeder and the air-pulverized mixture pipeline after entering the intermediate metering bin as required. The high temperature flue gas produced by pulverized coal combustion in the boiler furnace completes radiation and convection heat transfer, and then enters the bag filter and desulfurization device.

    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 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.
