Coal is burned to produce steam to spin the turbines to generate electricity. Carbon in the coal gives the energy to be able to make the steam. Bituminous coal leaves a residue called coke, which is used in the steel industry for smelting the iron ores together (Connor, 1997). Anthracite is used for heating due to its attribute of burning ...
