Abstract
A method of inhibiting vanadic corrosion of a hot part of a gas turbine system is provided. The method includes introducing, in the combustor, a first oxide comprising magnesium oxide (MgO) and at least one second oxide from among AlO, FeO, TiOand SiO. A ratio 'm' of a number of moles of MgO to a number of moles of VOand a ratio 'a' of a total number of moles of the at least one second oxide to the number of moles of VOsatisfy two conditions based on a firing temperature of the expansion turbine, an average density of one or more double oxides formed by a reaction between MgO and the at least one second oxide, and an average Knoop hardness of the one or more double oxides formed by the reaction between MgO and the at least one second oxide.
