    The resulting product, called powdered coal or pulverized coal, is then generally used in a fossil fuel power plant for electricity generation. Pulverised coal is a significant dust explosion hazard, as large quantities are suspended in air for transfer from the mill to the power plant.Coal Wikipedia,Coal is also used to produce very high temperatures through combustion. Efforts around the world to reduce the use of coal have led some regions to switch to natural gas and electricity from lower carbon sources. When coal is used for electricity generation, it is usually pulverized and then burned in a furnace with a boiler.

  • Improving Coal Pulverizer Performance and Reliability

    Pulverization is currently the favored method of preparing coal for burning. Transported by an air or an air/gas mixture, pulverized coal can be introduced directly into the boiler for combustion. There are several pieces of equipment involved in processing coal to be burned in this fashion. Figure 1 is a simplified diagramPulverised 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.
