What is the primary function of a pressure relief valve in a boiler?

The primary function of a pressure relief valve in a boiler is to release excess pressure and prevent explosions. This safety device is critical in ensuring that the boiler operates within its designated pressure parameters. When the pressure inside the boiler exceeds a set limit, the pressure relief valve opens to allow steam or fluid to escape, thereby reducing the pressure and preventing potential catastrophic failures, such as explosions or damage to the boiler and surrounding structures.

Understanding the importance of the pressure relief valve is crucial for maintaining safe operations. It serves as a vital protective mechanism that responds to abnormal pressure increases, ensuring the overall integrity of the boiler system. This function underscores the importance of regular maintenance and testing of pressure relief valves as part of boiler safety protocols.
