Processing Of Coal Into Coke

Coke Making Process

Coal is crushed and blended prior to being charged in a coke oven. A larry car charges the individual oven with the blended coal. In the coke oven, the coal is heated to 1,800°F for up to 18 hours. During that time, the volatiles of the coal are driven into the offgas and a pure carbon form called “coke” remains.

Coal Carbonization for Coke Production – IspatGuru

2018-12-8  Coal Carbonization for Coke Production. Coal carbonization is the process by which coal is heated and volatile products (liquid and gaseous) are driven off, leaving a solid residue called coke. Carbonization of coal involves heating coal to high temperatures either in the absence of oxygen (O2) or in control quantity of O2.

12.2 Coke Production - US EPA

2015-9-10  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 Manufacturing - IFC

In the coke-making process, bituminous coal is fed (usually after processing operations to con-trol the size and quality of the feed) into a series of ovens, which are sealed and heated at high temperatures in the absence of oxygen, typically in cycles lasting 14 to 36 hours. Volatile com-pounds that are driven off the coal are collected

How does coke and coal play into steel making? -

2016-6-22  Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel. Prior to the 1880’s, steel was produced using charcoal.
