The working principle of stainless steel flue gas heat exchangers

The stainless steel flue gas heat exchanger is a heat exchange device that uses the heat energy in the flue gas and transfers it to other substances in order to achieve energy recovery and utilisation. Its working principle can be summarised in the following steps:

Flue gas enters the heat exchanger: flue gas is produced in the industrial process and enters the stainless steel flue gas heat exchanger after a dust removal process.

Heat transfer: The heat in the flue gas is transferred to the medium (e.g. water, air, etc.) that needs to be heated in the industrial production process through the stainless steel piping in the heat exchanger shell in order to achieve energy recovery and utilisation. This process can be achieved by different forms of heat exchangers, such as tube heat exchangers, plate heat exchangers, etc.

Cooling the flue gas: In the process of heat transfer, the temperature of the flue gas gradually decreases. In stainless steel flue gas heat exchangers, the temperature of the flue gas drops to a certain level after heat transfer, which can further reduce the emission of pollutants in the flue gas and reduce environmental pollution.

Emission of flue gas: After the heat exchanger treatment, the heat in the flue gas is transferred to other media, while the flue gas itself becomes cooler. In the heat exchanger, the flue gas is cooled and then discharged into the atmosphere, reducing environmental pollution.

In conclusion, stainless steel flue gas heat exchangers achieve energy recovery and utilisation by transferring the heat in the flue gas to other media, while also reducing the emission of pollutants, making it a very effective technology for energy saving and emission reduction.
