Which of the following conditions will NOT be the result of a build-up of deposits in a gas turbine compressor?

Correct Answer: Option C — Reduced fuel consumption.

Compressor deposits restrict airflow and reduce compressor efficiency. To maintain a constant power output, the control system must increase fuel flow, leading to higher combustion gas temperatures and potential turbine blade corrosion. Reduced fuel consumption is impossible because the engine must work harder to compensate for the degraded aerodynamic efficiency.
