• The Steel Making Industry

    Coke is a solid carbon fuel and carbon source used to melt and reduce iron ore. Coke production begins with pulverized, bituminous coal. The coal is fed into a coke oven which is sealed and heated to very high temperatures for 14 to 36 hours. Coke is produced in batch processes, with multiple coke ovens operating simultaneously.

  • What Is the Difference Between Coal and Coke Fuel?

    When coal undergoes a process known as destructive distillation, it converts to coke. This process entails heating the fuel at a high temperature with no oxygen. The impurities and flammables burn off when coal changes to coke, and the result is a dull, porous substance with high carbon content.

  • What is Coking Coal

    Coke is produced by heating coking coals in a coke oven in a reducing atmosphere. As the temperature of the coal increases, it becomes plastic, fusing together before resolidifying into coke particles. This is known as the caking process.

    Coke is a product used in the steel making process; it's been used to fuel blast furnaces ever since Abraham Darby discovered the coking process in 1708. Coal would be brought into the plant by train and baked in oxygenfree furnaces until it was purified. The gas released, "coal gas," would be saved and channeled back into the furnaces ...

  • Metallurgical Coke

    Processing. Metallurgical coal is used in the production and purifiion of metcoke. It is during the heating process that the unstable components are released. The final product is a nonmelting, solid, stable carbon. However, the "ash" elements, which were part of the original bituminous coal, remain encapsulated in the resultant metcoke.
