  • Coal gasification Wikipedia

    From Wikipedia, the free encyclopedia Coal gasification is the process of producing syngas —a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen.

  • Pulverizer Wikipedia

    Hot primary air for drying and coal transport enters the windbox plenum underneath the grinding table and flows upward through a swirl ring having multiple sloped nozzles surrounding the grinding table. The air mixes with and dries coal in the grinding zone and carries pulverized coal particles upward into a

  • Coal mining Wikipedia

    11.04.2003· Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production.

  • Charcoal Wikipedia

    15.03.2002· Charcoal is usually produced by slow pyrolysis —the heating of wood or other organic materials in the absence of oxygen. This process is called charcoal burning. The finished charcoal consists largely of carbon. The advantage of burning charcoal compared to burning wood is the absence of water and other components.

  • Subcoal Wikipedia

    Subcoal is commercially used via various grinding media (direct firing); via a hammer mill (12 tonnes per hour), air-rotor mill (6 tonnes per hour) and via a bowl mill (4 tonnes per hour). Cement manufacturers, lime producers and energy providers spray the Subcoal powder with coal powder into their kilns.

  • Coal Simple English Wikipedia, the free encyclopedia

    Coal is a hard rock which can be burned as a solid fossil fuel. It is mostly carbon but also contains hydrogen, sulphur, oxygen and nitrogen. It is a sedimentary rock formed from peat, by the pressure of rocks laid down later on top. Peat, and therefore coal, is formed from the remains of plants which lived millions of years ago in tropical wetlands, such as those of the late Carboniferous

  • Fischer-Tropsch process Simple English Wikipedia, the

    Gasification is a dirty and expensive process. Coal-based Fischer–Tropsch factories start out with coal, gasify the coal, and then use the resulting gas as feed stock for the Fischer-Tropsch process. These factories can produce large volumes of CO 2 in this way. One of the main reasons for this approach is the large amounts of energy required for a coal-based gasification process. History
