2018-4-9·This injects steam into the feedwater to increase the temperature to 160°F to180°F or so to remove oxygen. Scale is a very effective insulator that will cause a loss of heat transfer efficiency and eventually tube sheet failure. Hard water results in a high amount of suspended solids. This condition is not covered under the boiler warranty. > Get A Quote >

Proper Boiler Feed Water Temperature Management

Pre-heating the feed water to achieve an ideal boiler feed water temperature will allow the boiler to run most efficiently as the heat input required to raise the temperature of the water up is reduced. The difference between 140°F and 180°F in boiler feed water temperature equates to about a 3-4% difference in boiler efficiency. > Get A Quote >
