Coal Properties

   

Bituminous coals are dense black solids, frequently containing bands with a brilliant lustre. The carbon content of these coals ranges from 78 to 91 percent and the water content from 1.5 to 7 percent. Bituminous coal is used for power generation, cement making and to provide heat and steam in industry.
