What is the total combined relief capacity of spring loaded safety valves?

  1. 50% of the max designed capacity

  2. 75% of the max designed capacity

  3. 100% of the max designed capacity

  4. 150% of the max designed capacity

The correct answer is: 100% of the max designed capacity

The total combined relief capacity of spring-loaded safety valves is established to be 100% of the maximum designed capacity of the boiler or pressure vessel they are protecting. This standard is crucial for ensuring safety, as safety valves are designed to prevent overpressure situations that can lead to catastrophic failures. By having a total relief capacity that equals the maximum designed capacity, the safety valves can effectively handle the release of excess pressure, maintaining the system within safe operating limits. This requirement ensures that if the system experiences an overpressure event, the valves will open and relieve that pressure adequately, thus preventing any possible dangerous incidents. The emphasis on 100% capacity is significant as it reflects industry standards and regulations established for boiler operations, ensuring the equipment operates safely while avoiding equipment damage or safety hazards.
