While making engine room rounds at sea, you observe excessive steam leaking from the forward gland on the high pressure turbine. This may indicate that the __________.
• Steam turbine gland sealing systems and why glands need controlled leakage • Effect of an obstructed leak‑off/expansion line on pressure at the gland • Relationship (or lack of it) between condenser vacuum, turbine speed, and gland leakage
• Think about what component is supposed to remove or control steam that escapes past the turbine glands. What happens if that path is blocked? • Ask yourself: would low turbine speed normally INCREASE or DECREASE steam leakage at the gland? • Consider whether excessively high condenser vacuum would make more steam rush OUT of the gland, or pull air IN toward the condenser instead.
• Identify which choice directly affects pressure build‑up at the gland itself, not somewhere else in the system • Eliminate any options that mainly affect overall turbine performance but not local gland leakage appearance • Confirm which option would most logically cause visible, excessive steam discharge at that specific forward gland.
