What is a Coke Oven? (with pictures)
In the coke-making process, treated coal is placed in the coke oven. Due to the high temperature inside, coal gas, coal water, and tar are separated from the coal. The gas and water then fuse together with carbon and the remainders of ash. The hard residue that remains at the end of this process is commonly referred to as coke.
