The Process of Coke Production

During the ignition process, the coal volatiles are sent into the off-gas while coke, often known as "pure carbon," remains. When exposed to air, the coke will instantly ignite and start to burn. When the pure carbon is driven to a railcar from the oven, it is quenched to cool and halt the burning process.
