Dry quenching coke oven is a cooling device different from coke oven. Red coke is loaded from the top of the dry quenching oven, and low-temperature inert gases (e.g., nitrogen) are drummed by the circulating fan into the red coke layer of the dry quenching oven’s cooling chamber to absorb the red coke’s heat, and this process reduces the coke’s temperature to less than 180°C.

The dry quenching oven is designed to cool the coke in the dry quenching chamber by using an inert gas. The cooled coke is discharged from the bottom of the dry quenching oven, while the high temperature inert gas from the ring flue of the dry quenching oven flows through the dry quenching boiler, where it exchanges heat with water to produce steam, which can be used to generate electricity or drive other industrial equipment.
