초록

A method details injecting water into a gas turbine engine to facilitate cleaning an inner surface of a combustor. The method comprises removing an axial fuel injector from the combustor, wherein the fuel injector includes a nozzle stem, and inserting a spray nozzle assembly into a fuel injector opening created within the combustor when the fuel injector was removed, wherein the spray nozzle assembly includes a popet nozzle that is coupled to a nozzle stem that is shaped substantially identically to the fuel injector nozzle stem removed from the combusto...
