Hard coking coal to fuel steel growth in India
Given our assumptions around the average furnace size, the use of stamp charging and prevalence of non-recovery coke ovens, CRU forecasts the average ratio of hard coking coal to semi-soft coking coal in the coking coal blend will increase from 65:35 in to 84:16 by .

Coke (fuel)
The industrial production of coke from coal is called cokingThe coal is baked in an airless kiln, a "coke furnace" or "coking oven", at temperatures as high as 2,000 °C (3,600 °F) but usually around 1,000-1,100 °C (1,800-2,000 °F) This process vaporizes or decomposes organic substances in the coal, driving off volatile products, including water, in the form of coal-gas and coal-tar.

The bulk of the worldwide coke production in was effected in conventional coking plants including a recovery of gas and coal chem icals These plants are very often called by-product coking plants, too Approx 5 % of the total coke production originate from the non-recovery technology, which does not recover gas and coal chemicals.

Metallurgical Coal and Coke Testing
testing in commercial coke ovens These tests are used to evaluate how coals and coal blends will perform in by-product coke ovens in terms of ease of pushing of the coke mass from the oven, coking pressure, and resultant coke quality SOLE HEATED OVEN (SHO) Tests done in the sole heated oven evaluate the contraction or expansion.

Non-Recovery Coke Ovens
Unlike the by-product type of coke plant, in non-recovery coke-making, coke oven slag and other by-products released from coking process are combusted within the oven This provides the heat required for the coke-making process The oven is a horizontal design and operates under negative pressure Primary combustion air is introduced though ports in the oven doors which partially combusts the.

Influence of coal fluidity on coal blend and coke quality
Jul 18, &#; Blending of non-coking coals above 20% with the hard coking coals used in this research decreases the blend fluidity and impairs the coke quality It was seen that the coals lose their fluidity on weathering, and the value becomes less than half after a two months of storage at site.
