After removing the coal from the ground, the miners may send it to a preparation plant near the mining site. The plant cleans and processes coal to remove rocks, dirt, ash, sulfur, and other unwanted materials. This process increases the heating value of the coal.
Aug 07, 2016· Coal plays a dual role in the Kiln. Part of coal is used as fuel to supply the desired heat so as to take the raw materials to the desired temp. But main role of coal is to supply carbon in the reduction process. Dolomite is used as sulphur scavenger which finally comes out with the char. Char contains ash of coal and other impurities of iron ore.
The coking coal is crushed and washed. It is then 'purified' or 'carbonised' in a series of coke ovens, known as batteries, where the coking coal is heated to 1000-1100ºC in the absence of oxygen for 12-36 hours. During this process, by-products are removed, and coke is produced. Iron
Jul 10, 2019· Further, coking coal available to Chinese industries is usually of poor quality, with most of it having high ash contents, large amounts of intergrowth and harmful impurities, making it difficult to obtain clean coking coal (Cheng et al., 2013). 20–30% middling coal with ash content more than 30% is produced during separation of raw coking coal.
Apr 12, 2016· At the washery, illustrated by flowsheet "A," the entire mine output is sold for coking coal. Mining the relatively narrow seam produces a product with 15 to 20% ash, although the coal when cleaned will carry only 3 to 3½% ash.

Coal or hydrogenation of coal involves raising the atomic hydrogen to carbon ratio. Coal can be converted to liquid and gaseous fuels by direct and indirect processing. Hydrogenation of coal is also called liquefaction of coal. The source of coal is from various coal mines. 33.2 Hydrogenation reaction: 4(C 3 H 4) n + nH 2 nC 6 H 6 + 5nC + nCH 4
The U.S. coal industry serves a vital role in the nation's economy by producing fuel for more than half of its electricity.
