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.

Superheated steam - Wikipedia

2020-6-22 · Superheated steam is steam at a temperature higher than its vaporization point at the absolute pressure where the temperature is measured.. Superheated steam can therefore cool (lose internal energy) by some amount, resulting in a lowering of its temperature without changing state (i.e., condensing) from a gas, to a mixture of saturated vapor and liquid.
