Waste heat recovery air cooled heat exchanger is a special equipment for coal-fired, oil-fired and gas-fired boilers, which is installed at the flue gas outlet to recover waste heat from flue gas to heat domestic water or boiler water; it can also heat air, and the hot air can be used for boiler combustion or drying materials.

Exhaust gas waste heat recovery equipment uses steel finned tubes (or high frequency welded tubes) to recover the heat of high temperature hot gas in industrial exhaust gas using the principle of heat exchange. That is, heating water or air to produce hot water, hot air, steam, while saving boiler fuel, improving energy utilization, reducing production costs and protecting the environment.

It is widely used in chemical, petrochemical, building materials, light textile, metallurgy, power, food, paper, electronic and electrical industries.
