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.

Fact sheet Energy use in the steel industry
• Coke, made by carburising the coal (i.e. heating in the absence of oxygen at high temperatures), is the primary reducing agent of iron ore, and other fuels are used to substitute a portion of coke. • Up to 75% of the energy content of the coal at an integrated facility is consumed in the blast furnace, where in the
