Of Coal And Coke
Coke Production
Coke Production General 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.

Influence of coal fluidity on coal blend and coke quality ...
· Coal fluidity is one such important coking property which highly influences the coke quality. The hard coking coals having good fluidity, which yield good coke, however are not only very expensive, but also are limited in reserves. Unlike, other properties, coal loses its fluidity on weathering, oxidation in presence of air on long storage ...
COAL EXTRACTION AND PROCESSING
Coal is also used in the creation of materials such as steel. Steel industries use a specific type of coal called coke. Coke is coal that has been placed in a coking oven to remove all parts of the coal that is not carbon. When coke burns it creates the high temperature and chemical reaction necessary to turn iron or into raw iron.
