CDQ Waste Heat Boilers

2021-07-29 17:24:19

The Coke Dry Quenching (briefly called CDQ) waste heat boiler uses inert gas to cool the coke, transports the heat-absorbing inert gas to the boiler, and then sends it to the coking production energy-saving equipment through a circulating fan for recycling in the CDQ coke oven.

Dry quenching device has many advantages such as energy saving, consumption reduction, cost reduction, environmental pollution reduction, and coke quality improvement. As the main energy-saving equipment in the CDQ coke production process, the main function of the CDQ waste heat furnace is to cool the circulating gas and generate steam. The new CDQ waste heat recovery system developed by ZBG Boiler is unique and has been widely used. It effectively overcomes the special problems of boiler sealing, abrasion and expansion, and has an excellent ability to adapt to the load changes of the CDQ system.
