Most modern boilers are not controlled by an ON/OFF switch as they did in the past if automatic. A pressure switch with a cut out at high pressure and a cut-in at some span below the high cut-off is a tad old-fashioned, though still used in domest

Gas pressure switches are a key component of your gas train to assure proper safety and operation of your burner. They prove you have adequate pressure to operate and will lock out your burner when you are either too low or too high of pressure. We stock many brands such as Ashcroft, Honeywell, Siemens, Antunes, and Dungs pressure switches.

2021-1-2 · Pressure in the HPR is maintained slightly below the lowest steam user in the system to facilitate the flow of condensate from the steam traps to the HPR. When steam is generated in the boiler, the carbonates decompose and produce C02 gas which is non-condensable. These gases are mixed with steam and enter the corrugator heating units.

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
