🔍 Key Concepts

• Function of an economizer relief valve in a boiler system • Relationship between drum safety valve, superheater safety valve, and economizer relief valve pressure settings • Effect of water pressure drop through the economizer on relief valve setting

💭 Think About

• How should the relief devices be arranged so that pressure is released in a safe, predictable order as boiler pressure rises? • Which component needs to lift first, which second, and which last to protect the economizer from overpressure? • How does the added pressure required to push water through the economizer influence the needed set pressure on the economizer relief valve?

✅ Before You Answer

• Compare each choice to the typical order of operation: drum safety valves, superheater safety valves, economizer relief valve • Check which answer accounts for both a fixed pressure margin (like 50 psi) and the water pressure drop through the economizer • Eliminate any choice that would allow the economizer to see a higher pressure than either the drum or superheater without a way to relieve it safely
