What can happen if a safety relief valve fails to operate correctly?

Pressure may remain stable
Boiler efficiency may increase
Pressure may exceed safe limits
No impact on boiler function

The correct answer is: Pressure may exceed safe limits

A safety relief valve plays a crucial role in maintaining safe operating conditions in a boiler by allowing excess pressure to escape. If the valve fails to operate correctly, it can lead to a dangerous situation where pressure builds up beyond the boiler's designed safe limits. This excessive pressure can result in catastrophic failures, including equipment damage, explosions, or even injuries to personnel. Understanding the function of the safety relief valve highlights the importance of regular maintenance and testing to ensure it operates correctly, as any failure in this component can have severe consequences for both the equipment and safety of the operating environment.
