Boiler Flue Gas Heat Exchanger | Flue Gas Waste Heat Recovery Exchanger Custom

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
