Flue Gas Boiler Heat Exchanger is an energy-efficient device designed to recover residual heat from industrial exhaust gases such as boiler flue gas, waste gas, and high-temperature air. It transfers heat from hot gases to cooler mediums (air or water), improving energy utilization, reducing emissions, and supporting green and sustainable industrial production.

Working Principle
The equipment operates on the principle of flue gas hydrothermal/heat transfer. High-temperature flue gas passes through the exchanger, transferring its heat to a cooler medium (such as water or air). This process heats the medium while significantly cooling the flue gas, effectively reclaiming heat that would otherwise be wasted.
Material Options
Available in several materials including Carbon Steel, Stainless Steel 304, Copper, and Aluminum to suit different operational conditions and media requirements, ensuring corrosion resistance and longevity.
