15 Ways To Increase Boiler Efficiency | Rasmussen Mechanical

1. Lower the Stack Temperature. Lowering stack temperatures may be as simple as a day/night set back that lowers the operating pressure on steam boilers or operating temperature on hydronic boilers when idling at night or on mild spring and fall days.. 2. Install an Economizer. An economizer uses the otherwise wasted hot flue gas to heat feedwater on its way to the boiler.

Steam Heating System Operating Temperature

Because a steam boiler makes heat by producing steam - by boiling water, at sea level, the temperature at the boiler will be boiling or 212 °F or close to that figure. The actual steam boiler temperature may be a bit lower at high elevations above sea level, and the steam boiler temperature will be a bit higher than 212 °F for boilers

Superheated steam - Wikipedia

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.
