Coke (fuel) - Wikipedia

Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low ...

Fossil Fuel Combustion Systems - EOLSS

Solid fuels such as coal may be burned in different ways. The most common method in large steam-generating units is to grind it to a fine powder and inject it into the furnace with a stream of air. For certain coals, particularly those with a low ash-melting temperature, combustion in a cyclone furnace is more appropriate. Here the coal is crushed and injected into swirling air in a cyclone ...
