Question 79Gas Turbine - 1st Asst/Chief

The correct answer is C) Calcium deposits which can clog cooling holes in the turbine section. High calcium levels in distillate fuels for gas turbines can lead to the formation of calcium deposits that can clog the critical cooling holes in the turbine section of the engine. This can disrupt the cooling of the turbine blades, leading to potential damage or failure of the turbine. The other options are incorrect because abrasive wear in the compressor (A) is not a typical issue with high calcium levels, clogged fuel filters (B) are more associated with particulate matter, and corrosion in the combustor (D) is not the primary concern with elevated calcium content in the fuel.
