coal processing coke

processing of coal into coke

The ‘Hearth’ process of coke making, using lump coal, was continued to be used in many areas during the first half of the 19th century. This process was similar to that of charcoal burning but using a heap of coals covered with coke dust instead of a heap of prepared wood, covered with twigs, leaves and earth.

How a Coke Plant Works - GASP

Oct 04, 2018  Coal is the main ingredient used to make coke. Iron is produced by inputting coal into a blast furnace. However, coal cannot be put directly into a blast furnace because of all the harmful by-products that come from that. So, there is an intermediate process that occurs. Coal is converted into coke first. Coke is used as fuel in a blast furnace.
