What are the two prime sources of deposits that build up on compressor blades?

🔍 Key Concepts

• How gas turbine or diesel engine air compressors become contaminated over time • The kinds of substances present in intake air on or near the ocean • Where oil mist and fuel spray normally exist in an engine or turbine system

💭 Think About

• Think about what the compressor is actually compressing and where its air comes from on a seagoing vessel. • Consider which listed contaminants are likely to be found in the intake airstream, not just inside bearings or fuel systems. • Ask yourself which pair of choices best reflects normal marine environmental conditions affecting air inlets.

✅ Before You Answer

• Be clear on whether fuel oil spray normally passes through the compressor section. • Decide which of the listed contaminants are carried in inlet air rather than generated deeper inside the engine. • Consider that marine atmosphere near the sea surface contains a particular common contaminant that can foul blades.
