    coal classification lignite

    Coal is a fossil fuel that forms when dead plant matter is converted into peat, which in turn is converted into lignite, then sub-bituminous coal, after that bituminous coal, and lastly anthracite This involves biological and geological process The geological processes take place over millions of yearsThe 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.

    what is s and sub bituminous coal

    Sub-bituminous coals are the second division of low-rank coals They are transitional between lignite and bituminous coal In the US rank classification, sub ,Coal Ranks Coal Types , The sub-bituminous coal found in the US is normally at leastmillion years old and representspercent of total US coal production, .The energy density of lignite is only about (18 MJ/kg), significantly lower than the contents of higher quality coals such as sub-bituminous, bituminous, and anthracite coal Uses Since lignite has a relatively low energy density, the coal is burned close to the mines (known as mine mouth operations).

    Classification Of Coal Type Subbituminous

    Bituminous coal: Bituminous coal, the most abundant form of coal, intermediate in rank between subbituminous coal and anthracite according to the coal classification used ,Bituminous coal: This coal is high in carbonaceous matter and is divisible into high-volatile, medium and low-volatile groups on the basis of increasing heat content Anthracite: Represents the final maturation stage of coal and is readily identified by its shiny surface.

    Coal Ranking

    Sub bituminous coal is a lignite that has been subjected to an increased level of organic metamorphism This metamorphism has driven off some of the oxygen and hydrogen in the coal That loss produces coal with a higher carbon content (71 to 77% on a dry ash-free basis) Sub bituminous coal has a heating value between and British Thermal Units per pound on a mineral ,In the process of transformation (coalification), peat is altered to lignite, lignite is altered to sub-bituminous, sub-bituminous coal is altered to bituminous coal, and bituminous coal is altered to anthracite.

    THE FORMATION OF COAL

    Low rank coals, such as lignite and sub-bituminous coals, are typically softer, friable materials with a dull, earthy appearance; they are characterised by high moisture levels and a low carbon content, and hence a low energy contentCoal comes in four main types or ranks: lignite or brown coal, bituminous coal or black coal, anthracite and graphite Each type of coal has a certain set of physical parameters which are mostly controlled by moisture, volatile content (in terms of aliphatic or aromatic hydrocarbons ).
