After quenching the coke is transferred to the blast furnace for use within the iron production process. The gas driven off the coal during the coking cycle is cooled, cleaned and useful by-products removed either for re-use or sale. Clean gas is recycled within the site as fuel for heat or electricity production.

Coal was heated strongly in the absence of air to form coal gas (a mixture of hydrogen, methane and carbon monoxide). A liquid (coal tar) was formed as a by-product which contained many useful organic chemicals, including benzene, and the solid residue was coke, an impure form of carbon. Coke was the source of what we now call synthesis gas.
