Flue Gas to Water Heat Exchanger recovers heat from high-temperature exhaust gas and transfers it to water or air. Flue Gas to Water Heat Exchanger lowers flue gas temperature, improves boiler efficiency, and reduces fuel costs. Commonly used in boilers, aluminum furnaces, and high-temperature drying systems.
Key Benefits
1.Energy Saving: Reuses waste heat to cut fuel consumption.
2.Durable: Seamless heat transfer structure, pressure-resistant up to 2.2 MPa, and corrosion-proof materials for long service life.
3.Eco-Friendly: Reduces emissions by improving energy utilization.
4.Low Maintenance: Stable flow design prevents corrosion and scaling.
5.Easy Setup: Modular design fits existing systems.
How It Works
Heat from flue gas is transferred to low-temperature media through efficient heat exchange surfaces, achieving continuous heat recovery and cooling of exhaust gases.
