CDQ waste heat boiler is used by coking industry, the inert gas is used as a medium to cooling high-temperature coke, the absorbed inert gas is passed to the boiler, and then fed into the coke oven by circulating fan for recycling, to achieve high-temperature waste heat recovery.

CDQ device has a good energy saving, reduce costs, reduce environmental pollution, sets of high quality coke and many other advantages. I developed this type of waste heat boiler has been widely used, it is an effective solution to the particular problem of boiler seals, wear, expansion, etc., fully able to adapt to the CDQ system load changes.
