Industry Problem
Boiler and process flue gas leaves at 120–220°C (or higher), carrying both sensible and latent heat plus a visible white plume that fails many local rules.
Exhaust Conditions
Flue gas is hot, moist, mildly acidic (low-temperature corrosion risk) and must be cooled without fouling.
Recovery Principle & Recommended Exchanger
Use a condensing plate or run-around coil to drop flue temperature below dew point and capture latent heat while eliminating the plume. Boiler flue-gas white-plume elimination recovers heat and clears the stack. For coating/textile flue, see flue-gas core.
System Configuration
- Condensing plate recovers sensible + latent; preheats combustion air or process water.
- Acid-resistant material (316L / coated) below dew point.
- Drain and treat condensed acid.
Energy-Saving Potential
Condensing recovery can lift boiler efficiency 5–12 points and remove the visible plume. See also heat exchanger in a boiler and exhaust gas recovery.
Material & Design Considerations
316L stainless or polymer-coated; corrosion allowance; condensate neutralisation; access for cleaning.

FAQ
Can I recover latent heat from flue gas?
Yes—cool the flue below its dew point with a condensing plate or run-around coil; that also removes the white plume.
