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

Abstract

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. Keywords: Fuel additives, Blade material, Molten solution, Thermodynamic corrosion prediction, Chemical equilibrium.
