Coal Classification. Coal is classified according to the nature of the original vegetation, the duration of its formation and – importantly – the depths and temperatures to which it has been subjected. There are several classifications; we use the ASTM classification by rank, which is based on fixed carbon and gross calorific value.

Bituminous coal, or black coal, is a relatively soft coal containing a tar-like substance called bitumen or asphalt.Its quality is ranked higher than lignite and sub-bituminous coal, but poorer than anthracite.Formation is usually the result of high pressure being exerted on lignite. Its coloration can be black or sometimes dark brown; often there are well-defined bands of bright and dull ...

What is coal classification? - AskingLot

What is coal classification? Based on maceral content and its appearance in a hand specimen, coal is classified into four principal types: clarain, durain, fusain, and vitrain. Coal may also be classified in grades using subjective terms (e.g., “low-sulfur coal,” “high-ash coal”) with reference to their impurities for commercial purposes.

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 coal are determined by carbon content.
