Abstract: A turbine engine cleaning system includes a foaming nozzle. The foaming nozzle includes a wall having a thickness between an outer surface of the wall and an inner surface of the wall. The outer surface of the wall is configured to contact a detergent in which the foaming nozzle is configured to be disposed. The inner surface of the wall surrounds an inner plenum of the foaming nozzle, and the inner plenum is configured to receive an aerating gas. The foaming nozzle also includes a first row of first through holes fluidly coupled to, and extending between, a first row of first through hole inlets at the inner surface of the wall and a first row of first through hole outlets at the outer surface of the wall. The foaming nozzle also includes a second row of second through holes disposed axially adjacent to the first row of second through holes with respect to a longitudinal axis of the inner plenum, where the second row of second through holes is fluidly coupled to, and extending between, a second row of second through hole inlets at the inner surface of the wall and a second row of second through hole outlets at the outer surface of the wall. The foaming nozzle also includes cross-sections of the first through holes and the second through holes having regular shapes.

Abstract: A turbine engine cleaning system includes a foam generator configured to generate foam, from a liquid detergent, to clean a turbine engine. The turbine engine cleaning system also includes an effluent capture and detergent regeneration sub-system having an inlet configured to receive an effluent from the turbine engine, processing components configured to process the effluent to regenerate a liquid detergent, and an outlet fluidly coupled with the foam generator to enable transport of the liquid detergent from the effluent capture and detergent regeneration sub-system to the foam generator.

Abstract: A method for cleaning components of a gas turbine engine is presented. The method includes introducing a working fluid into a gas flow path or a cooling circuit defined by the one or more components of the gas turbine engine such that the working fluid impinges upon a surface of the one or more components of the gas turbine engine, wherein the working fluid includes a plurality of detergent droplets entrained in a flow of steam. A system for cleaning components of a gas turbine engine are also presented.

Abstract: A system and method of cleaning a turbine engine are provided. The method may include inserting, directing and evacuating a cleaning agent. Inserting may include inserting the cleaning agent through a predefined access port into a cooling cavity defined by an internal wall of an assembled turbine component, while directing may include directing the cleaning agent against the internal wall to remove a foreign material therefrom. Evacuating may include evacuating the cleaning agent from the cooling cavity.
