### Solved: For Boiler At 8 Kg/cm2 (g) Steam Pressure. The Fol

Dec 30, 2019 · High pressure can result from the boiler temperature being set too high. Higher pressures generally cause automatic shutdowns. Modern boilers have built-in pressure release valves. These generally trip at 30 psi and release excess steam to bring the pressure back to normal. It'll also kick off the power to your boiler.

To generate steam, you have to reach at least 100C, or 212 degrees Fahrenheit. However, the more pressure that exists in the boiler, the higher the temperature can be. So you could have a boiler with a water temp of 450 degrees F. Someone who knows more about steam than I do can tell you what pressure it would be at in this condition.

### What Your Boiler Pressure Should Be When It's Heated

Pressure and Temperature gauge on hot water or hydronic heating boilers: this gauge displays the heating boiler internal pressure and temperature. Typical pressure for a residential boiler serving a two story home would show 12 psi cold, and less than 30 psi hot.

### How to Set Hot Water or Steam Heating System Pressure

Relationship of Boiler Pressure to Water Temperature in Steam Boilers. The temperature of heated water can exceed 212 °F when water is heated under pressure - producing superheated water than can flash to steam. See BLEVE EXPLOSIONS for details. 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.

### Steam Pressure Reduction: Opportunities and Issues

(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. Heat of Saturated Liquid (Column 4). This is the amount of heat required to raise the temperature of a pound of water from 32°F to the boiling point at the pressure and temperature shown.

### Steam Heating System Operating Temperature

Dec 15, 2015 · Boiler A – 600 psig. At 600 psig the temperature of your steam would be 486.38 F. At 600 psig your enthalpy is 1203.68 btu/lb. Boiler B – 300psig. At 300 psig the temperature of your steam would be 416.68 F. At 300 psig your enthalpy is 1202.85 btu/lb. The good news is that Boiler B, though it is half the pressure of Boiler A, still contains almost as much enthalpy or btu/lb.

For this example, when steam pressure was reduced from 130 psig to 80 psig, the actual temperature readings on the boiler surface showed an average reduction from 150°F to 140°F. Using the ABMA standard radiation loss chart, this would yield a savings of 0.2% of the fuel input. However, the ABMA chart does not apply to firetube boilers.
