What is the difference between coking coal and thermal coal? What is the Gross Calorific Value of coking coal? ... The coal which forms a hard and durable coke in cokeovens, suitable for use in blast furnaces, is called coking coal. Due to heating (approx. 1300*C), it looses it's volatile contents which burn, but ash forming mineral matters remain.
The major coal types ... Demand for this coal skyrocketed following the 1973 OPEC oil embargo and subsequent restrictions on natural gas use in new plants. Lignite, or "brown" coal, is the most abundant, youngest, and least mature of the coals, with some plant texture still visible. Its Btu values generally range below 8,300.

Lignite coal has the lowest carbon content about 45 per cent and the highest powder content. (iii) Bituminous Coal: Bituminous coals are subdivided into coking and noncoking coals and each one of them in turn is divided into gas coal and steam coal. Coking coal is .
The four stages in coal formation are peat, lignite, bituminous and anthracite. Each of these stages must be completed for coal to form. Stage one in coal production is peat. Peat is a fibrous substance that is oxidized by water and carbon dioxide. When a plant dies, and stays under water, it builds up an accumulation of peat.
