As the rank increases, so does the heat (or calorific value) given out by the coal when it burns. It is difficult to make a fire from lignite because the moisture content is so high. Sub-bituminous coal burns satisfactorily, and bituminous coal burns fiercely.

Sub-bituminous coal is used as fuel for steam-electric power generation. Also, it is a source of light aromatic hydrocarbons for the chemical synthesis industry. Bituminous coal is a dense rock, black but sometimes dark brown. It is a relatively soft coal that breaks and burns readily and quickly.

Uses and Properties of Bituminous Coal Bituminous coals also called soft coals or black coals are the group of coals that are the most abundant. It’s the type of coal that is most widely used in our world today. It’s been named so because of the presence of a tar-like & gluey type substance that is known as bitumen.

Carbonizing coal to produce a soft smokeless coke can significantly reduce the adverse health effects of burning raw coal or untreated coal briquettes. Carbonization describes the process for producing fuels – solid, liquid and gaseous – from coal and other carbonaceous materials such as biomass and organic wastes, by heating them in an ...

In bituminous coals, specific plant components in the coal (macerals) become more homogenous, and the cell structures of woody material within the coal (still visible in lignite and subbituminous coals using scanning electron microscopy) become significantly deformed (Hatcher et al., 1994; Hatcher and Clifford, 1997).

Subbituminous: This is the third rank of coal, possessing 35-45% carbon and more moisture than bituminous coal. This is the rank of coal that is currently mined in Alaska by Usibelli in the Nenana Coal Field south of Fairbanks.

Types of coal, lignite, subbituminous coal, anthracite, bituminous coal. The ranks of coal (from most to least carbon content) are as follows: anthracite, bituminous coal, subbituminous coal, and lignite.
