🔍 Key Concepts

• Steam turbine cooldown procedures and why slow rotation is used • How bearing lubrication and cooling are affected when a turbine is stopped • Difference between gear tooth, shaft, coupling, and bearing problems during shutdown

💭 Think About

• Think about what happens inside the turbine when it is hot and then suddenly stops turning. Which part is most likely to be damaged if it sits still while still very hot? • Which of the listed components depends most on a thin film of oil that works best when there is slow rotation rather than a dead stop? • Consider which failure would occur "immediately after being secured" rather than over long periods of misalignment or wear.

✅ Before You Answer

• Match the purpose of turning gear / jacking gear operation with one of the choices • Ask: which component is most sensitive to loss of oil film when the shaft stops but is still hot? • Eliminate options that usually relate to long‑term misalignment or load distribution problems rather than short‑term post‑shutdown protection.
