Guidance on Safe Operation of Steam Boilers

Jan 07, 2009 · ASME. requires a gauge with a scale of twice the boiler's rated pressure. For low pressure steam, this is 15 PSIG maximum so a 0-30 PSIG gauge is used, sometimes a compound gauge -30"Hg to +30 PSIG. There is nothing in the ASME boiler code that says such gauges must be useful

Steam Heating System Controls & Gauges: Photo Guide Repair

The pressure control switch on a steam heating boiler is designed to shut the heating system down should unsafe high pressures develop. As we emphasize at our description of pressure gaugesOn a steam boiler, residential steam heating systems are almost always designed to operate at very low pressures, perhaps around .5 psi - that' s 1/2 of one psi.

Understanding Steam Pressure Controls: Three - Boiler

If steam setpoint is 80 PSI, then modulation control should be set to 80 PSI, operator control to 88 PSI and the high limit control to 98 PSI with the safety valve setpoint at 150 PSI. These three basic controls are what you will find on almost every boiler.
