How to Create Coke in a Coal Pilot Plant or Testing Oven

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 ...

PDF Coke Production US EPA

Metallurgical coke is produced by the destructive distillation of coal in coke ovens. Prepared coal is heated in an oxygenfree 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 ...

PDF Steelmaking: The Coke Oven ByProduct Plant

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

process) at some coke plants before being used as fuel. The coke oven gas has a rather high heating value, in the order of 20 kJ/m3 (STP). Typically, 35 to 40 % of the gas is returned to fuel the coke oven combustion system, and the remainder is used for other plant heating needs (US EPA 1985b, van Osdell et al. 1979).
