Coke is made by heating coal in the absence of oxygen to about 2000 degrees Fahrenheit. Hard coking coal forms high-strength coke, while soft coking coal produces a lesser quality coke.
coking coal required for production of coke which is used in steel industries and non coking coal required for thermal power plants for steam production. coking coal required for production of coke which is used in steel industries and non coking coal required for thermal power plants for steam production.
Coals as straight or in blend which on carbonization produce hard coke are known as coking coals. Depending upon coking capacity, coking coals are divided into prime or hard coking coal, medium or soft coking coals and weakly or semi-soft coking coals. The coking coals are classified based on CSN, LTGK coke type, gieseler fluidity, vitrinite contents, mean maximum reflectace of vitrinite etc. On the other hand, coals which on carbonization produce powery mass are known as non-coking coals. Coals having CSN 0-1 and LTGK coke type of A and B are non coking coals. Dr. Tamal Kanti Das DGM, RDCIS, SAIL, Ranchi, India
caking index is the factor governing the coking capacity of coal,it is a number ,best coke can be obtained from coal which also named as prime coking coal(17-22 caking index bearing coal )produced as hard coke that is high carbon content upto 75-80% carbon used for steel industry whereas soft coke so obtained from having lower caking index and low carbon content below75% used at power industry. Coal is a combustible black rock consisting mainly of carbonized plant matter and used as a fuel coke is a solid fuel made by heating coal in the absence of air so that the volatile components are driven off. Carbon residue left after the incomplete combustion or distillation of fuels.
Coking coal is a type of coal that is used in the process of creating coke, a fuel used in steelmaking. It has a high carbon content and low impurities, making it ideal for this purpose. Caking coal, on the other hand, is a type of coal that softens and forms a solid residue when heated. This property is known as caking, and it is desirable for certain industrial processes such as coal gasification.
Approximately 770 kilograms of coking coal are needed to produce one ton of steel through the traditional blast furnace method. The coking coal is used as a fuel and as a reducing agent in the steelmaking process, where it helps convert iron ore into molten iron in the blast furnace.

No the coal will turn in to ashes and it is made to make long lasting fires.

Darby used the process of coking to remove chemical impurities from coal in 1713 because it produced a higher quality fuel with fewer impurities that burned more efficiently. Coking involves heating coal in the absence of oxygen to drive off volatile compounds and leave behind a cleaner, more pure form of carbon. This helped improve the efficiency of iron smelting and other industrial processes that relied on coal as a fuel source.
The bulk density of coking coal typically ranges from 0.8 to 1.5 grams per cubic centimeter, depending on the coal's composition and particle size. This parameter is important for determining the handling and storage requirements of the coal, as it affects transportation costs and storage capacity. Testing is usually done using standard procedures to accurately measure the bulk density.
The bituminous coals are considered to be 'all purpose' coals,and because of its excellent heating quality and the ease with which it can be handled, it is the most extensively used fuel in the world. In inditries it can be used for steam raising ,heating purposes, gasification, and coking
