Nowadays, Coke Dry Quenching (CDQ) plant has been regarded as essential facility as a counter-measure against environmental problems like global warming by CO 2 and air pollution. CDQ has widely spread especially in Asia. Because one large CDQ (single-chamber CDQ) is efficient than multiple small CDQ (multi-chamber CDQ) and this fact.
The lifter is automatic operated equipment for transporting red coke to dry quenching tower. Its main purpose is to lift the coke bucket loaded with red coke under the hoisting derrick to the top of the derrick, walk along the track above the CDQ tower, transport the red coke bucket to the top of the specific CDQ tower loading device, then slowly roll down the red coke bucket on the loading.

Two types of cleaning systems, dry and wet cleaning from hard substances are practised. In dry cleaning the following control systems are used, viz., inertial dust catchers, cyclones, electro-static precipitators and different types of cloth filters. While in wet cleaning scrubbers, wet cyclones and various kinds of venturis are used.

Coke Dry Quenching (CDQ) Coke dry quenching appears as the most valid system to reduce air pollution allowing at the same time a remarkable energy recovery or saving, especially when it is associated with coal preheating. In addition, dry quenched coke is harder and stronger, and its moisture content is much lower than that of wet quenched coke.
Coke Dry Quenching Plants with the latest automation systems. In the dry quenching process of coke, the red-hot coke is cooled by inert gases, instead of conventional water quenching. It effectively utilizes the thermal energy of red-hot coke, wherein 80 of the sensible heat of coke can be recovered and made use of for production of steam.
Korea POSCO Pohang coke plant (Stage 4) The traditional wet coke quenching system had been used in stage 5 coke plant. CDQ(Coke Dry Quenching) was adopted instead of existing wet quenching system. CDQ improved the energy recovery and the quality of coke for blast furnace which has been aiming at high productivity.
May 01, 2019 In this study, data with sample size 25,000 were collected from an actual coke dry quenching system in an iron and steel plant in China from May 1 to July 31, 2014. These operation data were collected every 5 min. Each process observation possesses 47 variables, 20 of which are meaningful for the economic efficiency research.
Coke is important raw material for iron production. Severstal increases raw material production to support their steel production independently from other coke and iron producer.

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 with inert.
In assessing the operational efficiency of dry-quenching units at coke plants, it is important to consider the coke losses. J IRON STEEL RES INT Coal dust explosion is a major threat to.
• Quenching where feasible, use dry instead of wet quenching. Filter all gases extracted from the dry quenching unit. If wet quench-ing, is used, provide interceptors (baffles) to remove coarse dust. When wastewater is used for quenching, the process transfers pollutants from the wastewater to the air, requiring subsequent removal. Reuse.
