What is the role of a safety valve in a boiler system?

The role of a safety valve in a boiler system is critical for safe operation. It is designed to prevent overheating and catastrophic failures by automatically releasing excess pressure that may build up within the boiler. In a scenario where the pressure exceeds the set limits, the safety valve opens to discharge steam, thereby reducing pressure and preventing potential damage or explosions. This mechanism ensures the boiler operates within its safe pressure range, protecting both the equipment and the facility.

Other options focus on different functions that are not related to the primary purpose of a safety valve. Increasing the boiling point of water pertains to the operational characteristics of the boiler, while controlling water levels and adjusting fuel intake relate to managing the operational efficiency and performance of the boiler rather than safety pressure management.
