• CASE HISTORY: AGGLOMERATION OF COAL FINES AT A FOSSIL .

    control systems permit the plant's generating units to convert 24,000 tons of coal into 56 million kilowatthours of electricity daily in a clean and acceptable way. In 1981, Pennsylvania Power Company installed a dustcollection system on its primary crushing system to collect dust fines generated at the crushers and conveyor transfer points. The dustcollection system removes the coal fines ...

  • COAL EXTRACTION AND PROCESSING

    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. After the water is heated it produces pressurized steam which is channeled through a turbine. As the steam is sent into the turbine it is forced to rotate and this rotation generates electricity. Coal is also used in the creation of materials such as steel. Steel ...
