What is the function of a safety valve in a boiler?

The function of a safety valve in a boiler is crucial for maintaining safe operating conditions. Specifically, safety valves are designed to release excess pressure when it reaches a predetermined level. This is essential in preventing catastrophic failures, such as explosions, which can occur if pressure inside the boiler exceeds safe limits. By automatically opening at specific pressure thresholds, safety valves ensure that the boiler operates within its designed parameters, protecting both the equipment and personnel from potential hazards.

While regulating temperature, controlling combustion, and measuring water levels are important aspects of boiler operation, they are handled by other components and systems. The safety valve specifically addresses the need for pressure control, making it a vital safety feature in any high-pressure steam system.
