coke oven plant process

Steelmaking: The Coke Oven By-Product Plant

The coke oven by-product plant is an integral part of the by-product cokemaking process. In the process of converting coal into coke using the by-product coke oven, the volatile matter in the coal is vaporized and driven off. This volatile matter leaves the coke oven chambers as

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.

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 ...

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 ...

What is a Coke Oven? (with pictures) - wiseGEEK

2021-02-17  In the coke-making process, treated coal is placed in the coke oven. Due to the high temperature inside, coal gas, coal water, and tar are separated from the coal. The gas and water then fuse together with carbon and the remainders of ash. The hard residue that remains at the end of this process is commonly referred to as coke.
