12.2 Coke Production 12.2.1 General 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.
A special, high-quality coal is turned into metallurgical coke for use in making steel. Coal is an energy resources composed of organic materials associated with ash forming inorganic minerals. It may be broadly classified into coking and non-coking coals. All coking coals possess the properties of softening to a plastic mass on carbonization,

Jun 01, 2014· Fig 1 Typical process flow and emission stream Coking coals and factors affecting coke quality Coking coal is an important raw material in the production of coke in the byproduct coke ovens since it decides the coke properties.The required coke properties are uniform size, good strength (CRI, CSR and micum values), porosity with minimum volatile matter and minimum ash.
"The art of making good coke," Andrew continues, "was a in controlling the damper and the height of the oven door to regulate the burning of the coal inside the oven. Usually in 72 hours, all the impurities were baked out of the coal, and good coke remained.
In addition to treating the coke oven gas, the by-product plant must also condition the flushing liquor that is returned to the coke oven battery, and treat the waste water that is generated by the coke making process. Top The by-product plant gas train The gas treatment processes in the by-product plant typically consist of the
Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low ...

Jun 01, 2019· Production of coal fines in coke making has lately become a problem worth addressing due to its negative impact on ecosystems. The use of coal fines is becoming an issue due to high Quinoline Insoluble formation during the carbonisation process as well as carry over or enhancement of carbon deposition in the upper parts of the coke ovens.
Coal is crushed and blended prior to being charged in a coke oven. A larry car charges the individual oven with the blended coal. 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…
