🔍 Key Concepts

• Gas turbine off-line water wash procedure sequence • Purpose of drying the engine after washing • Safety and mechanical considerations before introducing fuel and ignition

💭 Think About

• After you wash the inside of a gas turbine, what condition must the engine be in before you can safely return it to normal operation? • Think about which action would remove remaining moisture from the compressor and turbine sections without putting an immediate full load on the engine. • Consider which items must remain secured or engaged during a drying process, and which should only be changed when you are ready for a normal start.

✅ Before You Answer

• Verify which step is specifically associated with removing residual water from the gas path. • Check which options would normally be done before washing versus after washing in a maintenance/start sequence. • Confirm that the chosen step is something you would do right after the wash and before placing the turbine back in service under load.
