Capture Heat from Boiler Exhaust
The Flue Gas Heat Recovery Unit is designed to recover heat from boiler or generator exhaust gases. It reduces flue gas temperature from 150–200℃ down to 50–70℃, recovering a significant amount of thermal energy and improving overall system efficiency.
The heat contained in flue gas includes both sensible heat and latent heat. The system is designed to recover both types. The equipment significantly improves boiler efficiency and energy utilization.
High Efficiency Performance
The flue gas inlet temperature ranges from 150℃ to 350℃. The outlet temperature ranges from 90℃ to 120℃. The heat exchange efficiency is 60% to 80%. The flue gas resistance is below 200 Pa.
The heat exchanger is made of ND steel or stainless steel, both of which offer strong resistance to acid corrosion. The structure includes tube-type or finned-tube designs. The design life exceeds 10 years. The Flue Gas Heat Recovery Unit is engineered for long-term stable operation.
Key Advantages and Corrosion Resistance
The main advantage of our flue gas heat exchanger is its strong corrosion resistance. Flue gas typically contains sulfur compounds, which form acidic substances when combined with moisture. Ordinary steel materials are prone to corrosion under these conditions.
We use ND steel or stainless steel specifically designed for acid-resistant applications. The finned-tube design increases heat exchange surface area, improving overall efficiency.
We have been in business since 1996 and have extensive experience in flue gas heat recovery systems. Our products have been widely used in mine boilers and industrial boiler systems. Customers consistently report significant energy savings. The Flue Gas Heat Recovery Unit offers a strong return on investment over time.
