Safety Valve Setting Procedure: The boiler comprises of 2 safety valves set at different lifting pressures. The valve, which is to be set at lower pressure, is locked in position by the “gagging tool”. The valve not to be set is gagged when the boiler pressure reaches 80%. Raise the steam pressure and simultaneously tighten the gagging tool.Get a Quote

Boiler explosion - Wikiped
A boiler explosion is a catastrophic failure of a boiler.There are two types of boiler explosions. One type is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level. Corrosion along the edges of lap joints was a common cause of early boiler explosions.Get a Quote
Boiler getting overpressurized -- reaches 30 PSI and PRV .
Dec 03, 2014· But it definitely seems possible that the water is getting too hot and flashing to steam. When the boiler fires up, it only takes two minutes or so for the temperature gauge to jump 20-30 degrees and then the boiler shuts off. Seems possible that the boiler is overshooting and producing steam, due to an undersized or faulty pump, perhaps.Get a Quote
