plant. • Coke oven gas (COG) is the primary byproduct from the byproduct cokemaking process. After cleaning, the main components include 0% H 2, 2 % CO, 20% CH 4 and % CO 2. With a relatively high heating value of 18 MJ/Nm3, COG can be used in all heating applications on a steel plant, including heating of the coke oven battery itself.

It is thus important to ensure the coke is expansively tested. On a small testing scale, coke can be formed by the slow heating of coking coal in a refractory lined coal testing oven (CTO) to 1000 ˚C for 3 to 4 hours without the presence of air. The coal softens at a temperature of between 400 and 500 ˚C to form a plastic or liquid phase ...
