Question 46Gas Turbine - 1st Asst/Chief70% to pass
What are the two prime sources of deposits that build up on compressor blades?
AI Explanation
The correct answer is D) Lube oil mist and salt spray.
Compressor blades in marine engines can accumulate deposits from two primary sources:
1) Lube oil mist - The oil used to lubricate the engine can create a fine mist that settles on the compressor blades.
2) Salt spray - In marine environments, salt water spray can also deposit on the compressor blades.
The other options are incorrect because:
A) Carbon residue is not a primary source of deposits on compressor blades.
B) Salt spray is a primary source, but carbon residue is not.
C) Fuel oil spray is not a significant source of deposits on compressor blades.
