How pressuretrol works in steam boiler - Boilersinfo

When the steam pressure in the boiler drops 10 psi, the boiler will start up automatically. When the pressure reaches to 250 psi, it will shutdown the boiler. In case of modulating pressuretrol it controls the boiler firing at high and low within adjusted range with the help of modulating motor linked with fuel valve.

Boiler Ratings | Spirax Sarco

Shell boilers are often operated with feedwater temperatures lower than 100°C. Consequently the boiler is required to supply enthalpy to bring the water up to boiling point. Most boilers operate at pressures higher than atmospheric, because steam at an elevated pressure carries more heat energy than does steam at 100°C.

High Pressure vs. Low Pressure Boiler

By definition, a high pressure boiler is one that operates above 15 psi, while a low pressure boiler is one that operates at 15 psi or lower. Steam heating systems run with even lower pressure, typically at less than 1 psi in all. However, these types of boilers are less common (especially in newer homes), and operate using a different system.
