Question 67Gas Turbine - 1st Asst/Chief
70% to passWhich of the following conditions will NOT be the result of a build-up of deposits in a gas turbine compressor?
AIncreased combustion gas temperatures.
BRestricted air flow.
CReduced fuel consumption.
DTurbine blade corrosion.
AI Explanation
The correct answer is C) Reduced fuel consumption. A build-up of deposits in a gas turbine compressor will typically lead to increased combustion gas temperatures (A), restricted air flow (B), and turbine blade corrosion (D). However, the build-up of deposits will not result in reduced fuel consumption. Instead, the deposits will cause the compressor to operate less efficiently, leading to increased fuel consumption as the turbine requires more fuel to maintain the same power output.
