Overview of 1. gas-liquid heat exchanger
For the waste heat utilization of waste flue gas, in addition to the form of gas-gas heat exchange for waste heat recovery, in many processes need to use flue gas to heat the process hot water required in the process system or use circulating water to cool the flue gas. At this time, due to the large channel plate heat exchanger, plate thin and other characteristics, can not withstand the liquid pressure, the best heat exchanger selection for the tube fin heat exchanger.
The liquid heat transfer intensity is large, and the heat can be quickly transferred to the heat exchange material. The heat transfer area can be greatly expanded by adding fins to the material, so that the gas contacts more heat transfer area to enhance the overall heat transfer effect. Similarly, the flue gas cooling liquid heat absorption, the principle is the same, such as the use of cooling tower circulating water to cool the flue gas and then the flue gas desulfurization.
Introduction to the Principle of 2. Gas-liquid Heat Exchanger
The liquid heat transfer coefficient is generally up to 1000~3000W/(㎡ · ℃), and the gas heat transfer coefficient is generally only 30~80W/(㎡ · ℃), which limits the heat transfer between gas and liquid. Therefore, when the heat transfer performance of the medium on both sides is different, it is best to choose a finned tube fin heat exchanger.
