Wear Conditions and Anti-wear Measures in CDQ Waste-Heat ...

In the code dry quenching (CDQ) waste-heat boiler flue gas which contains large amounts of coke-powder particles can wear the heating surface pipes badly when rushing into the boiler. So the wear corrosion occurs. This paper analyzes the reason why wear erosion happens lists wearing sections. This paper summarizes various of preventive measures for instance installing anti-wear tiles improving

Coke Dry Quenching (CDQ) System | NIPPON STEEL ENGINEERING

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 1000°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.
