Steam Pressure Reduction: Opportunities and Issues

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.

What is the temperature of the steam in the boiler? - Quora

Over 30 psi boiler pressure will cause the pressure relief valve to open. Typical operating temperature settings on a boiler call for a Low temperature (boiler cut-in) between 120 and 160 °F. Typical operating temperatures on a hydronic boiler call for a high temperature (boiler cuts off) of 180-200 °F.

Dec 15, 2015 · The higher the pressure of a boiler the more heat must be applied to make steam. With the increased pressure, you in turn get steam at higher temperatures. Higher temperature steam contains more energy per pound, which is known as Enthalpy. Enthalpy is defined as the thermodynamic potential made up of energy and pressure. In the US, its common unit of measurement is BTUs/Lb. So, if the pressure on a boiler is greater, the BTU/Lb of steam

Then the steady flow energy equation for the throttling process becomes, hC = hB Hence, enthalpy after throttling = enthalpy before throttling hC = hf1 + x1 hfg1 If the pressure of the steam before throttling, the pressure and temperature of the steam after throttling, are known the value of x1 can be calculated using steam tables.

Jan 31, 2014 · Water boils at 212 at atmospheric pressure and the steam coming off of it is 212 also. If you go to the top of a mountain the pressure decreases and so does the boiling point of water. In a boiler pressure vessel as the water boils and steam is created this increases the pressure in the vessel which increases the boiling point.
