The principal combustible constituent in coal is carbon, with small amounts of hydrogen. In the combustion process, carbon and hydrogen compounds are burned to carbon dioxide (CO 2) and water, releasing heat energy. Sulfur in coal is also combustible and contributes slightly to the heating value of the fuel; however, the product
