ideal boiler feedwater temperature for electric boiler

Boiler Feed Water - Lenntech

Boiler feed water is used to produce steam. The pressure of the steam (0,5 - 100 bar) determines the temperature and energy capacity, but also the quality of the feed water. The general rule is the higher the pressure the more strict the quality of the boiler feed water. Problems caused by impurities in the feed water are: Scaling. Corrosion.
