The buildup of contamination in a gas turbine will cause all of the following conditions EXCEPT which one?

Correct Answer: Option C — Reduced fuel consumption

Contamination on compressor blades restricts airflow and degrades aerodynamic efficiency. This forces the engine to work harder to maintain power, leading to higher combustion temperatures and increased fuel consumption. Therefore, reduced fuel consumption is an impossible outcome of fouling; instead, specific fuel consumption increases significantly as efficiency drops.
