🔍 Key Concepts

• Function of gland sealing steam on turbine shaft glands • What happens if air leaks into a surface condenser and how that affects condenser vacuum • Relationship between shaft sealing, condensers, and overall turbine efficiency

💭 Think About

• Think about where the turbine shaft passes through the casing and what could leak in or out at that point during operation • Consider which of the choices, if lost, would most directly reduce the efficiency of a steam turbine and condenser system • Ask yourself: what is the main purpose of sealing around rotating shafts in a vacuum-type steam cycle?

✅ Before You Answer

• Identify which part of the steam cycle relies on maintaining a low absolute pressure (vacuum) • Decide whether gland sealing steam is meant to keep something from escaping or from entering at the shaft • Verify which of the options, when lost, would cause more air and non‑condensables to enter the system and reduce performance
