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 produced in a waste heat recovery boiler is used to generate electricity.

Apr 25, 2013 · Concept of Coke Dry Cooling. Hot coke is brought from the battery to the CDCP in bottom opening bucket kept on the quenching car. This bucket is lifted at the CDCP by a hoisting/charging device to the top of the CDCP chamber and red hot coke is discharged in the chamber for cooling. Hot coke (temperature around 1000 – 1100 deg C) is cooled in the chamber by the inert gas.
Feb 17, 2015 · dry topping — see dry-shake (preferred term) dry-batch weight — the mass of the materials, excluding water, used to make a batch of concrete. dry-cast process — a process for producing concrete products, such as pipe, using low-frequency high-amplitude vibration to consolidate dry-mix concrete in the form.
CDQ (Coke Dry Quenching) is a gradual coke quenching system, and improves coke strength and coke size distribution. Consequently, while the blending ratio of inexpensive non- or slightly-caking coal for coke oven material is only approx. 15% in case of CWQ (Coke Wet Quenching) system, it can be increased up to approx. 30% by CDQ, resulting in a cost reduction with raw materials for coke oven.
Ari Korkala, an electrical maintenance planner at the SSAB steel mill, explains the situation: “In the coking plant we have what is called the dry quenching stage where an elevator lifts a bucket of hot coke into the dry quenching chamber. The elevators are crucial and if there is a malfunction, the whole process stops since nothing can be lifted.

co-generation plant, has been installed in the No.3 coke oven plant of China Steel Corporation to replace the conventional wet quenching process. Figure 1 illustrats the process flow diagram of the installed CDQ system. As described above, the coke dry quenching process involves sophisticated heat, mass transfer and combustion phenomena.
Quenching Locomotive (QL) The basic function of the Quenching Loco is to pull or push the following quenching car and/or bucket cars with load of hot coke from one oven to the quenching tower/or CDQ for the dry quenching process. They also take the hot cake to the emergency quenching unit.
Abstract Analysis of the construction and operation of coke quenching chambers facilitates the identification of their deficiencies. The elimination of these deficiencies permits increase in operational efficiency of existing dry-quenching systems and the development of new high-performance systems.
2012/03/13 · Dry quenching of incandescent coke after it has been pushed from the coking ovens is a proved, reliable process that is presently being used in several industrialized countries. Foremost among dry ...
The application of slurry-phase hydroconversion to upgrade residue oil derived from the Canadian oilsands (CLVR) is hindered by the cost of the catalyst, in part because the catalyst is used once-through before being discarded as part of the solid product (coke). The goal of the present study was to assess the potential of recycling the slurry-phase catalyst under high residue conversion ...
I had not been long at school, stationed in that same chamber, when, having stood out for the foundation, and obtained admission to it, he became an occasional visiter, sometimes for days together, at the boarding-house, where he had formerly lived, and resumed his former situation of bedfellow to Mitford.
Traditionally dry quenching process is being adopted for the cooling of Coke produced from the Coke Oven Battery in Steel Plants. Water is used as cooling media to cool the hot coke which not only consumes large volume of water but also releases harmful pollutants which is also not permitted buy the government latest regulations.
incandescent coke mass is pushed from the oven and is wet or dry quenched prior to its shipment to the blast furnace.
Wet quenching method (e.g., for hot coke) is claimed that includes utilisation of the waste heat. A closed chamber is used to minimise the entry of air. In claimed embodiments, claims include the cooling process may be continuous instead of intermittent.
Subsequently to a 15 to 25 hours coking time the doors are opened and the built coke is pushed by the coke pusher machine out of the oven into a coke quench car.Then the coke is quenched in a dry or wet quenching facility. The oven chamber is sealedagain, initiating a new carbonization cycle.
