Deaerator efficiency/performance

Deaerator efficiency/performance

How do you calculate deaerator efficiency/performance?

RE: Deaerator efficiency/performance

Percent oxygen removal (for specified input conditions).

RE: Deaerator efficiency/performance


ASME publishes a "Performance Test Code" (PTC 12.3)outlining methods to test deaerators.

PTC 12.3 is the most widely accepted code for deaerator performance testing. DA vendors will offer units that have guaranteed performance to this code.

See these links:




Hope that this helps..............

Let us know more about the specifics of your installation and why you want to test?????????????


RE: Deaerator efficiency/performance

I use saturation conditions +/- 3F as my rule-by-thumb for deaerator performance check.  I like to check the oxygen content of the water exiting the deaerator and exiting the boiler feedwater pumps as X-checks.  I like to run the oxygen test in the absence of any oxygen scavenger.
