Lignite and sub-bituminous are considered low rank coals, characterized by light brown or dull black color, high moisture content, and a low heating value. By comparison, bituminous coal and anthracite are high rank coals, black and reflective in appearance with less moisture and a higher heating value from more fixed carbon. Sub-bituminous and bituminous coals are the most plentiful types of reserves

Anthracite Types of Coal

Anthracite is the most desirable type of coal because it contains more energy than other types and it is also the most environmentally friendly of them because of purity. Unfortunately, only approximately 1% of all the coal is anthracite. So we also burn bituminous coal, lignite (brown coal), and even peat which is the source material of coal.

Inside Power Station Coal

Jan 08, 2009Low rank coals (high moisture content) produce a "self pulverization" of the coal particles during combustion. As the inherent moisture in the pore structure of the coal is heated and expands rapidly, its volume increase (as water flashes to steam at atmospheric pressure, the volume expansion is 1600 to 1), thus fragmenting the coal particles.
