Background
At present, the dry quenching project is a method for cooling red coke by adopting inert gas. In the process of dry quenching, red coke is loaded from the top of a dry quenching furnace through a coke tank, low-temperature inert gas is blown into a red coke layer of a cooling chamber of the dry quenching furnace through a circulating fan to absorb the heat of the red coke, the cooled coke is discharged from the bottom of the dry quenching furnace, high-temperature inert gas coming out of an annular flue of the dry quenching furnace is subjected to heat exchange through a dry quenching boiler, the boiler generates steam, and the cooled inert gas is blown into the dry quenching furnace again through the circulating fan for recycling. The dry quenching is far superior to the traditional wet quenching in the aspects of energy conservation, environmental protection and coke quality improvement.
