What is a Coke Oven (with pictures)Info Bloom

A coke oven is a device used to produce coke a product that is derived from coal. The mixing and heating of bituminous coal at temperatures ranging from around 1832° to 3632°F (1000° to 2 000°C) within the airless oven yields the coke byproduct. This device is a crucial part of the coke-making process. Coke is a solid remainder of
