🔍 Key Concepts

• Relationship between set point pressure and normal working/operating pressure of a boiler • Purpose of a safety valve (protecting against overpressure, not routine operation) • Difference between maximum allowable working pressure (MAWP) and capabilities like overload or full‑power capacity

💭 Think About

• Ask yourself: Is a safety valve adjusted to open at the pressure where the boiler is normally run, or at a pressure related to its maximum safe limit? • Which choice refers to a safety or design limit of the boiler, and which refer to how hard you actually run it in service (capacity, overload, full power)? • Think about what condition the valve is supposed to protect against: everyday operation or dangerous overpressure beyond the normal operating range?

✅ Before You Answer

• Identify which option describes a pressure limit rather than a capacity or power output • Confirm that the safety valve set point must be tied to the boiler’s maximum safe pressure rating, not how much steam it can produce • Eliminate any answers that describe how much work the boiler can do (capacity/power) instead of how much pressure it is safely allowed to contain
