Nov 23, 2020 · Shell boilers are often operated with feedwater temperatures lower than 100°C. Consequently the boiler is required to supply enthalpy to bring the water up to boiling point. Most boilers operate at pressures higher than atmospheric, because steam at an elevated pressure … 1-10 tons steam boiler, 1.4-7 MW hot water boiler,1-10 …

square inch absolute. Gauge pressure (psig) plus 14.7 equals absolute pressure. Or, absolute pressure minus 14.7 equals gauge pressure. Pressure/Temperature Relationship (Columns 1, 2 and 3). For every pressure of pure steam there is a corresponding temperature. Example: The temperature of 250 psig pure steam is always 406°F.
