14/04/2019 · Coke dry quenching . In a Coke Dry Cooling process (CDCP) an inert gas is used for quenching of hot coke which does not require any water. Following are the advantages of dry quenching: 1. It conserves water and does not release any contaminants to either air or fresh water. 2. 80% of the sensible heat is recovered in a waste heat boiler and steam is generated. power is generated in a back pressure turbine from this steam
Coke Dry Quenching (CDQ) System. NIPPON STEEL CORPORATION / Nagoya Works / No.5 Coke Oven / CDQ. 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
25/04/2013 · Dry Quenching of Hot Coke. Coke dry quenching (CDQ) is an energy saving process used during the production of coke in the coke oven battery. A CDQ plant is also called coke dry cooling plant (CDCP). In the traditional CWQ (coke wet quenching) process, the red-hot coke which is pushed from the coke oven is cooled by spraying water on the hot coke.

The coke dry quenching equipment broadly consists of a coke cooling tower (pre-chamber and cooling chamber) and a waste heat recovery boiler. The entire process has as follows: Red-hot coke (approx. 1,200°C) is charged into the coke cooling tower, and inert gas is blown into the tower from the bottom.

13/09/2017 · Procedure for Boiler Refractory Dry out. Refractory baking and dry out cycle requires very slow and controlled heating of refractory as recommended by the refractory manufacturers. Thermal stresses will be produced if heating rate is too rapid. Longer period of low temperature drying causes more even heat distribution resulting better refractory dry out.
