Coke (fuel) - Wikipedia

The industrial production of coke from coal is called coking.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). 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.
