A modern coke oven consists of a carbonization chamber, a combustion chamber, a heat storage chamber, an inclined channel area, a furnace roof, a foundation, a flue, etc. The coal in the carbonization chamber is heated in an air-tight condition to become coke. The lifespan of a coke oven is generally about 25 years, and can reach more than 30 years if it is operated and maintained well. Modern coke oven types can be divided in many ways. The main differences between coke ovens with different structures are the following aspects: combustion chamber fire channel structure, adaptability to the type of heating gas, heating gas supply method, layout of the heat storage chamber and measures to improve high-speed heating uniformity.
