The operator control should be set about 5–10 PSI above the actual steam pressure you want to maintain in the boiler. This allows the boiler to reach low fire and if steam pressure keeps rising, it will shut down the boiler. The boiler will restart when the pressure drops below the differential set on the operator.
29/5/2021 · Low and High steam pressure-if steam demand drops, high steam pressure will shut down the burner and/or Main Engine speed reduced. A low steam pressure alarm will be given if there is a fault in combustion conditions. Air/Fuel Ratio- The air register damper
