What is the primary role of a safety relief valve on a boiler?

To prevent overheating of the boiler
To relieve boiler pressure when it exceeds the maximum allowable working pressure
To control the water level
To monitor fuel consumption

The correct answer is: To relieve boiler pressure when it exceeds the maximum allowable working pressure

The primary role of a safety relief valve on a boiler is to relieve boiler pressure when it exceeds the maximum allowable working pressure. This function is crucial for maintaining the safety and integrity of the boiler system. If the pressure within the boiler rises beyond its designed limits, it can lead to catastrophic failures, including explosions. The safety relief valve acts as a critical safety device by automatically opening at a predetermined pressure to release excess steam or water. This action helps to prevent the boiler from reaching dangerous pressure levels, ensuring safe operation and protecting both the equipment and personnel. In the context of other options, while preventing overheating is an important aspect of boiler operation, it is not the primary function of the safety relief valve. The valve does not control the water level or monitor fuel consumption, as these tasks are managed by different systems and components within the boiler operation framework.
