Boiler flue gas heat exchanger recovers waste heat from boiler flue‑gas, pre‑heats feed water / fresh air, reduces flue‑gas exhaust temperature, improves overall boiler efficiency. Custom build per drawing & working condition data.
Oval tube finned type
Anti‑dust, anti‑fouling, good for dusty boiler flue gas; low ash accumulation, easy cleaning
Tube material: carbon steel, 304/316L stainless steel, ND steel (dew‑point corrosion resistant)
Fin material: carbon steel, stainless steel
Key working parameters to confirm for custom
Boiler capacity
Inlet & outlet flue‑gas temperature
Flue gas flow rate
Media side: feed‑water / air inlet‑outlet temp, working pressure
Flue gas components (sulfur content → decide anti‑corrosion material / coating)
Dimension restriction, drawing available
Installation: vertical / horizontal layout
Main benefits
Recover flue gas waste heat, raise boiler thermal efficiency
Lower energy consumption
Optional anti‑dew‑point corrosion design
Custom per customer drawings or technical specifications
Common application
Gas‑fired boiler, coal‑fired boiler, biomass boiler, waste heat recovery system.
