Bituminous Coal Characteristics and Appliions

Thermal coal, sometimes called steaming coal, is used to power plants that produce steam for electricity and industrial uses.Trains that run on steam sometimes are fueled with "bit coal," a nickname for bituminous coal.

Coal Wikipedia

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal seams al is mostly carbon with variable amounts of other elements chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed if dead plant matter decays into peat and over millions of years the heat and pressure of deep burial converts the peat into coal.
