    What is foaming in boiler and how to prevent it ?

  • #2
    It is the formation of thick layer of steam bubbles on the top of the water surface inside the boiler due to:

    - High concentration of impurities.

    - By the animal or vegetable fats in feed water carry over from the oil heater.

    - Increase in level of dissolved & suspended solid TDS level.

    - Increase in water level.

    - To prevent foaming, surface or scum blow down should done frequently to expel any floating impurities for the boiler and no lube oil should be allowed to enter the boiler.
