There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbonrich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal ...

It is generally used for transfer of coal when filling of number of storage bin under the conveyor is required. The coal is discharge at the bottom of trough. Transfer capacity is about 10 to 100 tons per hour. In thermal power plant the coal is first grind into powder which burns faster and produces more heat.

Steam coal, also known as thermal coal, is suitable for electric power production. Steam coal is ground into a fine powder that burns quickly at high heat and is used in power plants to heat water in boilers that run steam turbines. It also may be used to provide space heating for homes and businesses.

It is an enclosed pressure vessel in which water is converted into steam by gaining heat from any source (coal, oil, gas etc). Boiler in thermal power plant accumulates the steam and build up a pressure to expend it in turbine and convert thermal energy to mechanical energy. The generator which is connected to turbine converts the mechanical energy into electric energy.
