The purpose of a pressure relief valve in a boiler is to prevent excessive pressure buildup by releasing steam. This safety device is crucial for maintaining the integrity of the boiler and protecting it from potential hazards associated with overpressure conditions. When the pressure within the boiler exceeds a pre-set limit, the pressure relief valve opens to allow steam to escape, thereby reducing the internal pressure to a safe level. This operation is vital because excessive pressure can lead to catastrophic failures, including explosions, if not managed properly.

The importance of the pressure relief valve cannot be overstated, as it plays a key role in ensuring safe operation within the design parameters of the boiler. This mechanism provides peace of mind to operators and ensures compliance with safety regulations. The correct function of the pressure relief valve is critical in the overall safety management system of boiler operations.
