Coke Dry Quenching (CDQ) System | NIPPON STEEL ENGINEERING

CDQ is a system where hot coke removed from coke ovens at a temperature of approximately 1,000°C is cooled and kept dry with inert gas and the resulting steam produced in a waste heat recovery boiler is used to generate electricity. As the sensible heat recovered by heat transfer in the cooling chamber is utilized as a heat source for steam

US9057023B2 - Method and device for keeping coke furnace

A process for keeping coke oven chambers hot during the stoppage of a waste heat boiler. The coke oven chambers are kept hot after emptying using externally heated burners, in which a flue gas low in pollutants is obtained from the burners. The waste heat boilers which, during normal operation, cool the flue gases can be shut off and overhauled, and a flue gas low in pollutants which can be
