Coke Dry Quenching - e Plant Maintenance

Cooling of hot coke by using inert gas is known as Coke Dry Quenching and is available as an alternate quenching metod. The coke wet quenching has following disadvantages1The sensible heat of coke is lost to the atmosphere.2.part of water gets evaporated into atmosphere 3.The steam carries cynide,sulphide,phenol and dust in the atmosphere.4.water also carres dust,and other pollutants into the ...

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 1,000°C is cooled and kept dry with inert gas and the resulting steam ...

Coke Dry Quenching Systems - Paul Wurth

Coke Dry Quenching concept fl owsheet Process features The coke dry quenching (CDQ) process utilizes an inert gas to cool the red hot coke and re cover sensible heat. The hot coke is transferred from the oven to the cooling chamber where it is charged from the top and the cooling gas is blown from the bottom. After a cleaning section

Dry Quenching of Hot Coke – IspatGuru

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.

Coke dry quenching for iron and steel sector | Climate ...

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.

Thermodynamic analysis of a coke dry quenching unit ...

Jan 01, 2000 · 2. The coke dry quenching (CDQ) system. To quench coke in the steel making industry means to cool it from approximately 1100 to 200°C in order to inhibit its combustion and gasification. The CDQ technique was introduced in Switzerland by the Sulzer brothers in the 1920s.

INTRODUCTION OF CURRENT TECHNOLOGIES FOR COKE DRY QUENCHING ...

coke is quenched with CDQ and the electric power is provided from it. By an installation of CDQ, both the ecological and economic advantages can be enjoyed enormously. (2) Prevention of dust emission during coke quenching In general, much amount of coke dust contained in steam (approx. 300-400 g/t-coke) is emitted from the wet quenching tower.
