    Coke (fuel) - Wikipedia

    Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air — a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.Coke (fuel) - Wikipedia,A fire brick chamber shaped like a dome is used, commonly known as a beehive oven. It is typically 4 meters (13.1 ft) wide and 2.5 meters (8.2 ft) high. The roof has a hole for charging the coal or other kindling from the top. The discharging hole is provided in the circumference of the lower part of the wall.How is Steel Produced? | World Coal Association,Global steel production is dependent on coal. 70% of the steel produced uses coal.
