122 Coke Production
The primary purpose of modern coke ovens is the production of quality coke for the iron and steel industry. The recovery of coal chemicals is an economical necessity, as they equal approximately 35 percent of the value of the coal. To produce quality metallurgical coke, a high-temperature carbonization process is used.
Coal carbonization is a process that yields metallurgical coke for use in iron-making blast furnaces and other metal-smelting proc-esses. Carbonization entails heating the coal to temperatures as high as 1300 C in the absence of oxygen to distill out tars and light oils. A gaseous by-product, referred to as coke-oven gas, together

Coke Making Process
In the coke oven, the coal is heated to 1,800 F for up to 18 hours. During that time, the volatiles of the coal are driven into the offgas and a pure carbon form called coke remains. The coke, when exposed to oxygen, will immediately ignite and begin to burn.
122 Coke Production
Metallurgical coke is produced by the destructive distillation of coal in coke ovens. Prepared coal is heated in an oxygen-free atmosphere coked until most volatile components in the coal are removed. The material remaining is a carbon mass called coke. Metallurgical coke is used in iron and steel industry processes primarily in blast furnaces to reduce iron ore to iron.
The Process Of Coke Production
During the ignition process, the coal volatiles are sent into the off-gas while coke, often known as pure carbon, remains. When exposed to air, the coke will instantly ignite and start to burn. When the pure carbon is driven to a railcar from the oven, it is quenched to cool and halt the burning process.
