  • 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.

    Pulverized coal. Pulverized-coal combustion is widely used in large power stations because it offers flexible control. In this method, coal is finely ground so that 70 to 80 percent by weight passes through a 200-mesh screen. The powder is burned in a combustion chamber .

    Used in steelmaking, but it is not indispensable like met coal. It is a softer, non-coking coal which is pulverized and injected into the blast furnace to supply heat, which in return reduces energy use and emissions. It does not play a role in the iron-steel conversion, and cannot replace hard coking coal .

    Almost all coal plants operating today use "pulverized coal" (PC) technology, which involves grinding the coal, burning it to make steam, and running the steam through a turbine to generate electricity. As with sulfur dioxide, coal burning is the leading source of mercury emissions in the United States.
