Understanding Boiler Pressure | Boiler

What defines a high pressure boiler? If you are unfamiliar with boilers and the power of steam you might expect high pressure to mean anything over 100 PSI. This seems reasonable right? 100 is a big three-digit number but did you know that a high pressure boiler is defined as having a max allowable working pressure (or MAWP) above 15 PSI?

Steam Calculators: Boiler Calculator

Using the Steam Property Calculator properties are determined using Steam Pressure and the selected second parameter (Temperature Specific Enthalpy Specific Entropy or Quality). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Pressure = 676.7 psig; Temperature = 325.0 °C
