Q

If the maximum steam generating capacity of a boiler is increased, 46 CFR Subchapter F (Marine Engineering) requires that the safety valve's __________.

🔍 Key Concepts

• 46 CFR Subchapter F requirements for boilers and safety valves • Meaning of relieving capacity versus lifting pressure • What changes (if any) are required to safety valves when boiler steam-generating capacity increases

💭 Think About

• Ask yourself: If the boiler can now make more steam per hour, what must the safety valve system be able to handle so the boiler is still protected? • Which option talks about the amount of steam the valve can pass, rather than the pressure level at which it opens or closes? • Think about which adjustments could compromise safety if changed incorrectly (opening pressure, reseating pressure, or blowdown).

✅ Before You Answer

• Verify in 46 CFR Subchapter F that safety valves must prevent pressure from rising more than a certain amount above the maximum allowable working pressure (MAWP). • Identify which term refers to the valve’s ability to discharge sufficient steam to keep pressure within safe limits. • Make sure you distinguish between pressure settings (opening/closing) and capacity (how much steam can be relieved).
