What is the purpose of a boiler's safety relief valve?

• A. To ensure efficient fuel combustion in the boiler
• B. To prevent overpressure by releasing excess steam or fluid
• C. To enhance the heating capacity of the boiler
• D. To control the temperature of the water used

Answer: (B)

The purpose of a boiler's safety relief valve is to prevent overpressure by releasing excess steam or fluid. In a boiler system, it is crucial to maintain a specific pressure range for safe operation. If the pressure exceeds the safe limit due to a variety of factors such as a malfunction or temperature increase, the safety relief valve activates to release steam or fluid. This helps to prevent the risk of catastrophic failures, such as explosions or ruptures, which can occur if the pressure gets too high. While efficient fuel combustion, enhanced heating capacity, and temperature control are important aspects of boiler operation, they do not address the critical function of the safety relief valve. Its primary role is focused on maintaining safety by regulating pressure in the system, making it an essential component for protecting both the boiler and the surrounding environment from potential hazards.
