🔍 Key Concepts

• Relationship between engine fire and residual heat in a gas turbine after shutdown • Location and purpose of temperature sensors shown near hot-section components in the illustration • Which component, if overheated, could indicate continuing risk of re‑ignition or structural damage after fuel is secured

💭 Think About

• Look at where the fire actually burns during normal operation and which part of the engine gets the highest internal temperatures • Ask yourself: after the fuel is shut off and the fire is out, what component could still stay extremely hot and possibly damage surrounding structure or reignite pooled fuel? • Compare which of the listed locations would be expected to cool slowest and be most directly exposed to the flame during an internal fire

✅ Before You Answer

• Verify which of the four answer locations lies directly within the primary hot gas path in the illustration • Check where temperature probes are typically installed for turbine inlet/EGT (exhaust gas temperature) monitoring on marine gas turbines • Confirm which choice would best indicate whether the fire is truly out or if dangerous hot spots remain in the core
