How a Coke Plant Works - GASP

2018-10-04· Coal is heated to about 1250 degrees Celsius in the coke ovens. This process is referred to as 'dry distillation' because these coke ovens are oxygen free, so the coal does not actually burn. This process takes around 18 hours to convert 35 tons of coal into 25 tons of coke.

12.2 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. Over 90

Schematic Diagram of Coke Oven Battery. During carbonisation, coking coals undergo transformation into plastic state at around 350o-400o C swell and then resolidify at around 500o-550o C to give semi-coke and then coke. In coke ovens, after coal is charged inside the oven, plastic layers are formed adjacent to the heating walls, and with the progress of time, the plastic layers move towards

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. When the coke is pushed from the oven into a railcar, it is quickly quenched to cool the coke and stop the burning process. The
