Boiler (power generation) - Wikiped

The fire is positively cut off when the pressure reaches a pre-determined point, usually set at 750 psi (5.2 MPa), cold water pressure; a safety valve set at 1,200 lb (544 kg) provides added protection. The fire is automatically cut off by temperature as well as pressure, so in case the boiler were completely dry it would be impossible to damage the coil as the fire would be automatically cut off by the temperature.
