processing of coal into coke

History of Coke - Mining History Resources - Coal Culture ...

Andrew, who often helped his father at work, describes the coke process: "A high grade of washed, crushed coal was loaded in special cars, called "larries," which are pulled by small engines called "dinkies". A track ran across the top of the ovens. The larries dropped their load of coal into the ovens through a hole at the top.

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.

How a Coke Plant Works - GASP

How a Coke Plant Works. 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.

During the processing of coal to get coke, coal tar and coal gas are also obtained. Explanation. Coal gas is obtained during the processing of coal to get coke. It is used as a fuel in many industries situated near the coal processing plants. Coal gas was used for street lighting for the first time in London in 1810 and in New York around 1820.

How does coke and coal play into steel making ...

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.
