  • Coal Wikipedia

    Coal is also used to produce very high temperatures through combustion. Efforts around the world to reduce the use of coal have led some regions to switch to natural gas and electricity from lower carbon sources. When coal is used for electricity generation, it is usually pulverized and then burned in a furnace with a boiler.

  • Coal National Geographic Society

    Bituminous coal is divided into three major types: smithing coal, cannel coal, and coking coal. Smithing coal has very low ash content, and is ideal for forges, where metals are heated and shaped. Cannel coal was extensively used as a source of coal oil in the 19th century.

  • What are the different types of coal? American

    The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or “ranks,” of

  • What is clean coal technology? HowStuffWorks

    18-7-2007· Some clean coal technologies purify the coal before it burns. One type of coal preparation, coal washing, removes unwanted minerals by mixing crushed coal with a liquid and allowing the impurities to separate and settle. Other systems control the coal burn to minimize emissions of sulfur dioxide, nitrogen oxides and particulates.

  • How Is Coal Extracted? Reference

    Coals mines use surface mining for coal deposits buried less than 200 feet underground. In this type of mining, giant machines remove top-soil and layers of rock to expose large beds of coal. After coal extraction, the topsoil is replaced so that the area can be reused for croplands, wildlife habitats, recreation or offices.
