Question 46Gas Turbine - 1st Asst/Chief

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.
