Coal-Fired Thermal Plant. Doosan Heavy Industries & Construction is supplying comprehensive engineering, from the manufacturing of key power equipment such as boilers, turbines and generators to design, construction and commissioning, by taking part in a number of coal-fired thermal power plants around the world.
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams.The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure.
Power Plant Retirements. By mid-2016, AEP will have retired approximately 6,500 megawatts (MW) of coal-fired generating capacity as part of AEP's plan for complying with the Mercury and Air Toxics Standards for existing power plants that were approved by the U.S. Environmental Protection Agency in December 2011.
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.
