🔍 Key Concepts

• Effects of fuel-borne contaminants on gas turbine hot-section components • Difference between erosion, deposit formation (slagging/fouling), and corrosion • Role of salts and combustion products at high temperature in attacking turbine blades and nozzles

💭 Think About

• Ask yourself which contaminant is most likely to form chemically reactive compounds at turbine temperatures that attack metal surfaces, rather than just physically erode them. • Think about which contamination would still be present as a vapor or molten deposit in the hot section, capable of reacting with metal alloys, instead of remaining as solid particles. • Consider which option is commonly associated with "hot corrosion" in marine gas turbines operating in coastal or sea environments.

✅ Before You Answer

• Identify which option is directly tied to sodium or other salts that can lead to hot corrosion when burned. • Eliminate any options that mainly cause mechanical wear (erosion) rather than chemical attack on metals. • Eliminate options related to low-temperature fuel properties that do not significantly affect the hot section’s corrosion behavior.
