High-temperature flue gas heat exchangers are used for waste heat recovery in high-temperature flue gases from industrial furnaces such as annealing furnaces, glass kilns, blast furnaces in steel plants, incinerators, boilers in thermal power plants, and incinerators. They also include industrial air coolers.

In terms of waste heat recovery and air cooling or condensation, plate-type flue gas heat exchangers offer better heat transfer efficiency compared to tube-type exchangers, especially when dealing with higher volumes of air and higher flue gas temperatures. The modular design and installation of flue gas plate heat exchangers allow for flexible selection of plate materials based on the chemical properties of the heat transfer medium, making them particularly suitable for handling high-temperature and strongly corrosive flue gases.

Furthermore, under similar operating conditions, the overall cost and subsequent maintenance and replacement costs of plate-type heat exchangers are significantly lower than those of tube-type heat exchangers.

Other advantages of plate-type high-temperature flue gas heat exchangers include high heat transfer efficiency, high waste heat recovery rates, and wide temperature control ranges, similar to those of conventional plate heat exchangers.
