Coke Oven: A chamber of brick or other heatresistant material in which coal is heated to separate the coal gas, coal water, and tar. The coal gas and coal water fuse together with carbon and the remaining ash, forming a hard residue commonly referred to as coke. Coke is primarily used in steel production. There are two types of coke ovens: (1 ...

The coke oven byproduct plant is an integral part of the byproduct cokemaking process. In the process of converting coal into coke using the byproduct coke oven, the volatile matter in the coal is vaporized and driven off. This volatile matter leaves the coke oven chambers as hot, raw coke oven gas.

The original blast furnaces at Blists Hill, Madeley In 1709, Abraham Darby I established a cokefired blast furnace to produce cast iron. Coke's superior crushing strength allowed blast furnaces to become taller and larger. The ensuing availability of inexpensive iron was one of the factors leading to the Industrial Revolution.
