  • Coal: Types and characteristics SpringerLink

    Coal is a complex agglomeration of organic and inorganic material originally deposited as a peat bog. The type of coal which is produced from peat is influenced by a number of factors including the final level of maturation (burial) of the coal, type of original vegetation and the degree to which the vegetable matter has been preserved during accumulation.

  • Coal - Origin of coal Britannica

    Coal - Coal - Origin of coal: It is generally accepted that most coals formed from plants that grew in and adjacent to swamps in warm, humid regions. Material derived from these plants accumulated in low-lying areas that remained wet most of the time and was converted to peat through the activity of microorganisms. (It should be noted that peat can occur in temperate regions [e.g., Ireland and ...

    Peat energy in Finland describes peat energy use in Finland. Peat has high global warming emissions and high environmental concerns. It may be compared to brown coal or worse than this lowest rank of coal.Peat is the most harmful energy source for global warming in Finland. (Hard coal, which is more harmful, is only used as an emergency back-up source for energy, and not in every year.)

  • Coal - Simple English Wikipedia, the free

    Peat is not yet coal. Lignite (brown coal) is the dirtiest coal, is about 60%-70% carbon, and is used as fuel for electric power generation. Jet is a compact form of lignite that is sometimes polished and has long been used as an ornamental stone. Sub-bituminous coal is used as fuel for steam-electric power generation. Also, it is a source of light aromatic hydrocarbons for the chemical ...
