🔍 Key Concepts

• Steam turbine construction around nozzles and diaphragms • Purpose and design of shaft seals vs. diaphragm seals • How a labyrinth-type restriction controls steam leakage without contact

💭 Think About

• Think about which device is specifically designed to control steam leakage between stationary and rotating parts inside a turbine stage. • Which option works by using a series of close clearances and pressure drops, rather than a liquid or solid contact seal? • Which of the listed components is normally associated with shaft bearings or protection, not with controlling steam flow between nozzle diaphragms and the rotor?

✅ Before You Answer

• Identify which choice is a non-contact sealing arrangement commonly found in steam turbines. • Eliminate any options that are mainly used for bearing surfaces instead of sealing. • Ask yourself: which device reduces leakage by creating multiple small throttling points rather than one tight seal?
