Why is Coke used instead of coal?

Coke may be combusted producing little or no smoke, while bituminous coal would produce much smoke.

Is Coke a clean fuel?

Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. The carbon monoxide produced by its combustion reduces iron oxide (hematite) to the iron product. Although coke is more expensive than coal, it can be used in households as a clean fuel, relatively free of smoke and impurities.
