Boiler Plume Abatement Demonstration

Vapor plume abatement is an important issue as boilers and water heaters have become more efficient. Exhaust flue gas temperatures have decreased, with the byproduct of the lower flue gas temperature being a higher dew point. As the warm moist air exits the exhaust duct, the water vapor condenses as it is cooled by the ambient air, creating a visible plume.

The new video shows how the system works.
