A few domestic plants preheat the coal to about 260°C (500°F) before charging, using a flash drying column heated by the combustion of coke oven gas or by natural gas. The air stream that conveys coal through the drying column usually passes through conventional wet scrubbers for particulate removal before discharging to the atmosphere.

Coke is a grey, hard, and porous coal-based 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 ...

A Caking coal, when heated in a similar way, leaves a solid coherent residue. The caking coal might give a coke which may not be accepted by the steel plants as it does not possess the requisite physical and chemical properties of the coke. A coking coal is that coal which on heating in absence of air leaves a solid residue.

Production normally takes place in a coke battery located near an integrated steel mill. In the battery, coke ovens are stacked in rows. Coal is loaded into the ovens and then heated in the absence of oxygen up to temperatures around 1,100 degrees Celsius (2,000 degrees Fahrenheit). Without oxygen, the coal does not burn; it begins to melt.
