This lower pressure operation, combined with the shorter distance between the water/steam interface and the steam outlet pipe, further increase entrainment. Older boilers, while much larger, have a larger steam space which can tolerate greater changes in steam demand without severe changes in steam pressure or water level.

The pressuretrol serves to turn the boiler off it the pressure rises above the cutoff setting -- which in your case should be 1 on the diff and 1 on the main, or even better 0.7 on the main. Reset it to where it was! What it doesn't do is raise the pressure in the boiler. The fact that your 0 to 5 psi gauge doesn't move, and the pressuretrol

Energy in fuel enters the boiler (energy input 100 percent). From the boiler, 4 percent of heat loss is through radiation and convection, 18 percent is in flue gasses and 3 percent is in blowdown. Energy in heating medium (e.g. steam) exits the boiler. Energy output (boiler thermal efficiency) is between 75 and 77 percent.

Boiler has too much pressure. A have a boiler that is building around 25 psi of pressure and spitting out a little bit of water from the pressure relief valve. The backflow preventer is installed and also the pressure reducing valve (set at 12 psi). The tank (air scoop) has/is known to have the correct pressure (12 psi) and to have no leaks.

To ensure high dryness fraction of steam, the boiler should be operated close to design pressure. Often boiler operators operate the boiler at pressures much lower than the design pressure primarily to reduce the fuel consumption. However, operating the boiler at low pressure leads to significant deterioration of the steam quality.

Once the water reaches saturation temperature (the temperature at which it will boil at that pressure) bubbles of steam are produced, which rise to the water surface and burst. The steam is released into the space above, ready to enter the steam system. The stop or crown Valve isolates the boiler and its steam pressure from the process or plant.

Standard physics laws of temperature and pressure are used to measure the explosive potential of boilers and pressure vessels. New calculations show, for instance, that if liberated in a rupture, a 30-gallon hot-water tank at 90 psig (or 104.7 psia) has approximately 314,095 foot-pounds of energy to flash its water into steam at 332°F.
