Coking plant Coal is needed when producing liquid hot metal in the blast furnace. However, we cannot utilise coal directly in the blast furnace as it contains a lot of harmful and unnecessary by-products. Coal is furthermore not strong enough to carry the blast furnace load. This is why we start by converting our coal into metallurgical coke.

The coal is baked in an airless kiln, a "coke furnace" or "coking oven", at temperatures as high as 2,000 °C (3,600 °F) but usually around 1,000-1,100 °C (1,800-2,000 °F). [19] This process vaporises or decomposes organic substances in the coal, driving off volatile products, including water, in the form of coal-gas and coal-tar.
