COAL EXTRACTION AND PROCESSING

the process of subsurface coal extraction and thermal coal processing. Purpose Coal is used for its potential heat energy when burned and since the 1880s has been widely used to generate electricity in power plants. To to generate electricity coal is first burned inside a power plant and the heat generated by the coal is then used to heat water.

Coal Drying Improves Performance and Reduces Emissions

power plant, less coal needs to be fired. This reduces the burden on the coal handling system, conveyers and crushers. Also, since dryer coal is easier to convey, this reduces maintenance costs and increases availability of the coal handling system. Crushed coal is fed into the bunkers from where it flows by gravity to the coal feeders.
