50 Questions and Answers For Marine Engineers

3. Marine boilers burning H.F.O. face a problem of cold corrosion due to high sulphur content. The minimum flue gas temperature within any boiler part is kept above due point of H 2 SO 4. The actual dew point of H 2 SO 4 in flue gases depends on the: A. Boiler furnace temperature B. Ambient air temperature C. Boiler operating pressure

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
