Deaerator

The deaerator is a direct exchange type open feedwater heat exchanger where condensate mixes with steam to be heated and sent to the feedwater pumps. Non-condensable gases in the condensate are released in the deaerator and vented to the atmosphere. Use of the deaerator is common in most power plants but less so in PWRs where chemicals are more commonly used to control the oxygen content.
