How does coke and coal play into steel making?
· Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel. Prior to the 1880's, steel was produced using charcoal.
Coal and Coke
Brown coal is a solid pit coal formed from peat. The youngest type of coals contains 6570 % carbon and is brown in colour. It is used as a domestic fuel and a chemical feedstock. This coal has a high water content (43 %) and therefore a low heat of combustion. It also contains a large number of volatile substances (up to 50 %).
