High Temperature Hot Corrosion Control by Fuel Additives (Contaminated Fuels).

The potential of fuel additives to minimize corrosion of blade-material has been analyzed by the following series of steps first, a computer program was employed for an equilibrium-thermodynamic prediction of condensed solution composition next relevant physico-chemical properties of the molten solution were estimated based on predicted equilibrium composition then oxide solubility and dissolution rates are calculated for this solution in contact with various solid oxides. Finally, we compare our predicted oxide dissolution-rate results with available experimental hot corrosion rate data, seeking verification of the model for the rate determining process - i.e., oxide dissolution - in hot corrosion.
