Coke Dry Quenching (CDQ) System NIPPON STEEL

2021-10-14  Coke Dry Quenching (CDQ) System. CDQ is a heat recovery system to cool the hot coke from coke ovens. It is one of the most renowned energy-efficient and environmentally-friendly facilities within steel production. CDQ is a system where hot coke removed from coke ovens at a temperature of approximately 1,000°C is cooled and kept dry

Failure Analysis of the Liner Plate of CDQ Chamber Made

2015-8-14  Coke dry quenching (CDQ) is an alternative to the traditional wet quenching of the coke. Coke is cooled using an inert gas in dry cooling plant, instead of cooling by sprayed water which results in high CO 2 emissions and thermal energy loss. This process allows the recovery of the thermal energy in the quenching gas which can then be used for the production of steam and electricity.
