Proper Boiler Feed Water Temperature Management | Powerhouse

The difference between 140°F and 180°F in boiler feed water temperature equates to about a 3-4% difference in boiler efficiency. Feed water preheating typically occurs in either the feedwater tank or deaerator using supplementary steam. Pre-heating the feedwater is the most basic method of mechanical deaeration, or the process of removing dissolved oxygen from water.
