  • Lignite - Wikipedia

    Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat.It has a carbon content around 25–35%, and is considered the lowest rank of coal due to its relatively low heat content.Lignite is mined all around the world and is used almost exclusively as a fuel for steam-electric power generation.

  • What are the types of coal? - USGS

    Lignite: Lignite coal, aka brown coal, is the lowest grade coal with the least concentration of carbon. Lignite has a low heating value and a high moisture content and is mainly used in electricity generation. The precursor to coal is peat. Peat is a soft, organic material consisting of partly decayed plant and mineral matter.

  • Coal - Wikipedia

    Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

  • Coal explained - U.S. Energy Information Administration

    Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce. The rank of a coal deposit is determined by the amount of pressure and heat that acted on the plants over time.
