Aug 22, 2017 · How do low pressure steam boilers work. Low-pressure steam heating is just what it sounds like: the steam from the boiler is pushed out to the building at a low pressure as opposed to high. Low-pressure boilers generally stay between 10 and 15 psi and the temperature is maintained under about 300 degrees F.

The table above is based on steam with pressure 300 kPa (3 bar) (or 50 psi in imperial units). Latent heat of saturated steam is 2133 kJ/kg ( 912 Btu/lb). 1 N/m2 = 1 Pa = 1.4504 x 10-4 lb/in2 (psi) = 1x10-5 bar.

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.

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. A commercial boiler system heating a high-rise building may be operating at much higher pressures, perhaps 20 to 40 psi in order to be able to force steam to 20 or 40 floors of building

Steam boiler systems typically require saturated steam, which means the water and the steam in the vessel must be at the same temperature. In a low pressure boiler the pressure does not exceed 15 psi and the temperature will not rise above 250 degrees F. Low pressure steam boilers do not need to be monitored regularly and usually only have to be checked when they begin to break down.
