How to Measure the Efficiency of a Deaerator

Horizontal DeaeratorA deaerator is a specialized piece of equipment used with a boiler.  It’s purpose is to dissolve oxygen through a mechanical process to reduce the need for water treatment with chemicals.  It effectively removes other gases as well, which protects the boiler from being pitted or corroded so it has a longer lifespan.

Measuring the technical efficiency of a deaerator depends on it’s operational effectiveness in the amount of oxygen it removes from the boiler’s feed water. In addition, measurements are taken for the amount of gas that shows up at the inlet of the storage tank and what the amount is at the feed water’s outlet.

Goals of a Deaerator

In order to be considered at it’s optimal working condition, a deaerator needs to achieve the following goals:

  • Ensuring the cold water is heated so it prevents thermal shock to the boiler.
  • Removing the dissolved oxygen to reduce the need for water treatment chemicals.
  • Eliminating all other dissolved gases to prevent corrosion and pitting from carbonic acid.
  • Doing away with other non-condensable gases to bolster steam efficiency.
