Preheating the boiler feed water prior to entering the deaerator minimizes the use of low pressure steam in the deaerator. There are some important points to remember when specifying a system to preheat undeaerated boiler feed water. If too much preheating is done this may cause problems in the operation of the deaerator.

Boiler Carryover - Industrial steam

the fault does not lie with the boiler feed pump. In nearly every instance, we have found excessive boiler carryover to be the culprit. In other words, boiler water is leaving with the steam which results in water requirements exceeding pump capacity. Low pressure boilers are primary offenders although high pressure units are sometimes responsible.
