1.2 Raw Materials and Its Preparation For Iron Making ...

• Before charging coal into coke oven chamber, it has to be crushed to at least 80 % below 3mm, so that adequate bulk density of 800-900 kg/m3 is obtained. • Also sufficient surface area is exposed when the coal begins to liquefy during the heating cycle thereby producing strong coke at the end of carbonisation.

Coal: Anthracite, Bituminous, Coke, Pictures, Formation, Uses

Coke production remains an important use of coal. Coke is produced by heating coal under controlled conditions in the absence of air. This drives off some of the volatile materials and concentrates the carbon content. Coke is then used as a high-carbon fuel for metal processing and other uses where an especially hot-burning flame is needed.

12.2 Coke Production - US EPA

12.2 Coke Production 12.2.1 General Metallurgical coke is produced by the destructive distillation of coal in coke ovens. Prepared coal is heated in an oxygen-free atmosphere (–coked–) until most volatile components in the coal are removed. The material remaining is a carbon mass called coke.

Coke. Coking coal is converted to coke by driving off impurities to leave almost pure carbon. 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.
