coke oven

A coke oven is a specialized oven, typically made of refractory brick, used for the carbonization of coal. This process heats coal to high temperatures (up to 900°C or more) in the absence of air, transforming it into coke. Coke is a solid residue primarily composed of carbon, with smaller amounts of other elements.

Modern coke ovens are large industrial structures, often arranged in batteries, capable of processing significant quantities of coal annually. The process is highly mechanized to ensure efficiency, minimize pollution, and reduce labor. The resulting coke is crucial for metallurgical uses, such as in blast furnaces for iron production, and in other industrial applications like making lime and magnesia. The hot gases released during carbonization are also processed to recover valuable by-products like tar, ammonia, and benzol.1234
