Steam Heating System Operating Temperature

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

How Is The Low Temperature Corrosion of Boiler Caused

Low temperature corrosion often occurs in the air preheater, but when the fuel sulfur content is higher, the boiler air coefficient is larger, so that SO3 in the flue gas content is higher. The dew point is higher, and the water supply temperature is low, the economizer tube may also occur low temperature corrosion.
