Abstract
Methods are provided for cleaning and inhibiting the formation of fouling deposits on jet engine components during the combustion of turbine combustion fuel oils. Methods are also provided for inhibiting the formation and emission of soot and smoke from jet engine exhaust during turbine combustion fuel oil combustion. The methods employ a derivative of polyalkenylthiophosphonic acid added to the turbine combustion fuel oil. The preferred derivative is pentaerythritol ester of polyisobutenylthiophosphonic acid.
Claims4
