Fuel for the blast furnace is coke, which is produced from coal by a process similar to that used to turn wood into charcoal. The coal is heated in a closed space with very little air. This prevents the coal from just burning up, and causes it to turn into coke, which is a more pure form of carbon than plain coal, and burns hotter in the furnace.
During the coking process, gases are released from the coal which are recovered and made into a variety of useful chemicals.
Coal arrives in railroad cars or in barges, and is fed into the crusher, which reduces it to a smaller and more consistent size. Another conveyor belt carries it to a storage bin. When needed, it is dumped into the larry car, which loads a measured amount of coal into the individual coke ovens.
After the coal has become coke, it is pushed out of the ovens into a quench car. This car rolls under the quench tower, where water arrests the burning process, and cools the coke for transport.
After quenching, the coke is dumped out on a conveyor belt. From this belt, it either goes on railroad cars, trucks, barges, or additional conveyor belts. Whatever the method of transportation, the coke finds its way to the blast furnace.
This is where it mixes with iron ore and limestone, to heat and reduce the iron out of the iron ore.
