Abstract
A method of operating of a gas turbine engine to inhibit vanadic corrosion of the gas turbine engine is provided. The gas turbine engine burns a vanadium-contaminated fuel and includes a component configured to be in contact with combustion gases. The method includes introducing into a combustion system of the gas turbine engine a first oxide and at least one second oxide. The first oxide includes magnesium oxide, and the at least one second oxide includes at least one of aluminum oxide, iron (III) oxide, titanium dioxide, and silicon dioxide. The method further includes cleaning at least a portion of the component using a cleaning agent containing a liquid vector and at least one descaling material that is suspended in the liquid vector. The at least one descaling material is an inorganic material.
