High-pressure steam locomotive - Wikipedia

In the later years of steam, boiler pressures were typically 200 to 250 psi (1.38 to 1.72 MPa). High-pressure locomotives can be considered to start at 350 psi (2.41 MPa), when special construction techniques become necessary, but some had boilers that operated at over 1,500 psi (10.34 MPa).

No pressure at boiler gauge Heating Help: The Wall

That isn't much pressure (we're talking ounces here). The pressure doesn't really build until the vents or traps shut (depending the type of steam system) -- at which point, the boiler should shut down for a while; the steam already in the system will condense (providing heat still) and the pressure will drop and so

Steam Calculators: Boiler Calculator

Step 1: Determine Properties of Steam Produced 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 = 796.8 psig; Temperature = 531.4 °C

Temperature of steam versus water in a boiler - Espresso

Oct 16, 2009· This water is under line pressure (or pump pressure), which is MUCH higher than the pressure of the steam boiler, usually. At that pressure, the high temperature is below the boiling point in the environment, so the water remains liquid. if it didn't, a heat exchanger wouldn't work because the steam would prevent the thermosyphon loop from flowing.

How to Fix Rising Boiler Pressure | DoItYourself.com

Too much water in the expansion tank and too little air may also cause pressure to rise frequently. If the bottom of the tank does not feel hotter than the top, it indicates an excessive amount of water. You need to drain this water from the tank. To do so, first turn the boiler off. Then close the water shutoff valve and allow the system to cool.
