🔍 Key Concepts

• Gland sealing steam purpose and where it is used on a turbine propulsion unit • How labyrinth packing works to control steam leakage around a rotating shaft • The difference between a vacuum leak, flooded hotwell, and piping restriction in terms of steam flow demand

💭 Think About

• Ask yourself: What condition would make you need MORE sealing steam than normal, not less? • Which of the listed problems would cause sealing steam to escape rather than be properly contained or returned? • For each choice, picture what happens to the steam path at the glands—does it increase leakage, reduce vacuum, or block the return flow?

✅ Before You Answer

• Verify which condition would cause increased leakage past the shaft glands, directly raising sealing steam consumption. • Check which options would more likely show up first as vacuum problems in the condenser instead of higher sealing steam demand. • Confirm which condition would cause backpressure or reduced flow, which usually leads to lower, not higher, steam usage.
