Steam Calculators: Boiler Calculator

Mar 17, 2015 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

Relationship of Boiler Pressure to Water Temperature in Steam Boilers. The temperature of heated water can exceed 212 °F when water is heated under pressure - producing superheated water than can flash to steam. See BLEVE EXPLOSIONS for details. However a residential steam boiler pressure is so modest (0.2 psi to 0.5 psi) that the temperature increase above 212 °F will be no more than about 220 °F.

Today's Lesson in Physics: The relationship between steam

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.

Pressure-Temperature Relationship of Water & Steam. Click on a word to view animation. Saturated (dry) steam results when water is heated to the boiling point (sensible heating) and then vaporized with additional heat (latent heating). If this steam is then further heated above the saturation point, it becomes superheated steam (sensible heating).
