Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.

Introduction. Coal is the dominating fuel source used in thermal power plants for generation of electricity. At the coalfired thermal power plants, the raw coal is first pulverized to the shape of flour before it is forcefed to the furnace. During the pulverization process, the clay particles entrapped in the cracks of coal get separated ...

Most of the coalfired power plants have efficiencies less than 35% by using indigenous high ash coal. Now a day, efforts are taking place to bring in highly efficient super critical technology in the country for thermal power plants. Energy analysis of coalfired power plant is done using mass and energy balance equation [2].

A coalfired thermal power station is a power plant in which the prime mover is steam driven. Water is heated, turns into steam, and spins a steam turbine, which drives an electrical generator, as schematically shown in Fig. After it passes through the turbine (one to three stage), the steam is condensed in a condenser and recycled to ...

Coal is a sedimentary deposit composed predominantly of carbon that is readily combustible. Coal is black or brownishblack, and has a composition that (including inherent moisture) consists of more than 50 percent by weight and more than 70 percent by volume of carbonaceous material. It is formed from plant remains that have been compacted, hardened, chemically altered, and metamorphosed by ...

Bituminous coal. Bituminous coal, or black coal, is a type of coal containing a tarlike substance called bitumen or asphalt. Its coloration can be black or sometimes dark brown; often there are welldefined bands of bright and dull material within the is typically hard but quality is ranked higher than lignite and subbituminous coal, but lesser than anthracite.
