Plume Abatement Explained

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.

So what is vapor plume abatement? It is simply the process of eliminating the visible vapor plume by removing the water in the flue gas exhaust.

Plume abatement can be important for a variety of reasons such as

  • Aesthetics

    The exhaust plume is made up of water vapor, but a neighbor or a community may perceive it as unwanted, smoke-related or even "dangerous". This may also be annoying and can even negatively affect property values.
  • Safety

    A freezing plume can be a safety hazard. It can create ice on sidewalks and driveways. Or icicles can form, break off and cause personal injury when they fall. Community concerns regarding visibility can be removed by significantly reducing visible plume.

    The outdoor part of a venting system can clog up with ice from freezing flue gas condensate. Most condensing boilers have safety system that prevent operation if the vent clogs up. But this prevents operation of heating boilers and water heaters, when you need them the most.

  • Damage Limitation

    Water is increasingly becoming a scarce and valuable commodity. Removing water from the vapor plume can help decrease water-related costs and help the environment.
  • Design Flexibility

  • Water Conservation

    Water is increasingly becoming a scarce and valuable commodity. Removing water from the vapor plume can help decrease water-related costs and help the environment.
