The function of a safety valve on a marine boiler is to prevent the pressure in the boiler from rising above __________.

🔍 Key Concepts

• Boiler safety valve purpose – what condition is it protecting the boiler shell and drum from? • Difference between design/test pressures (like hydrostatic test) and normal operating limits • Regulatory term MAWP – maximum allowable working pressure used in boiler codes

💭 Think About

• Ask yourself: Is a safety valve set to protect against normal operating overpressure or against extreme test pressures that are only applied under controlled conditions? • Think about which one of the listed pressures the boiler will actually see in regular service, hour after hour at sea. • Consider which term is used in codes and nameplates to define the highest safe pressure for continuous operation, not for testing.

✅ Before You Answer

• Identify which option represents the boiler’s continuous safe operating limit, not a one‑time test limit. • Distinguish between test pressures (hydrostatic or accumulation tests) and the pressure that the boiler is allowed to reach during routine steaming. • Check which term you would expect to find stamped on the boiler nameplate as the limiting working pressure.
