Peat, regarded as a precursor of coal origination, comprises the plant remains that its some part has decomposed but some still is in the decomposition process. Therefore brown-blackish stem, branch or leaf can be seen. The low carbon content of peat is around 50-60% by mass. It contains the high level of oxygen and humidity, but can be used as fuel.

    Lignite, a type of coal with little plant remains, is dark-brown to black coal. The carbon quantity is rather low, and the sulfur is high. The humidity is up to 30-70%. Lignite almost is used as fuel and regarded the low-quality coal.

    Sub-bituminous is dark-brown to black coal. Its matter is wax-like soft, not very solid. The carbon content of sub-bituminous is around 71-77%, but low sulfur. This type of coal is almost used as fuel for electricity production or industries. Generally it is utilized to be fuel in various industries such as boiler for baking.

    Bituminous is a tight, solid coal, and usually comprises the shining, deeply coal layer. The carbon content of bituminous is lower than that of anthracite. This type can be divided in 3 groups according to the ability of evaporation i.e. high, medium, and low levels. Bituminous is appropriate for metal smelting or electricity production, depending on the quantity of carbon and ability of evaporation.

    Anthracite is a type of coal classified in the highest rank and deemed as the best quality coal. It’s shining, black, and flashing. The carbon content of anthracite is up to 90% or more. Its humidity is much low and the Calorific Value is high. This type is hard-combustible and less smoking.  Anthracite usually is used to be fuel source in order to generate the household heat, and in glass industry, chemical industry, etc.
