Abstract: The present disclosure provides methods and systems of generating flows of detergent through a turbine engine to effectuate cleaning of components thereof. The methods include introducing a foamed, acid-including detergent with a pH range of between 2 and 7 into a gas flowpath of the turbine engine. The methods also include creating a pressure differential in an aft portion of the gas flowpath with respect to a forward portion of the gas flowpath to generate a flow of the detergent therethrough. The methods further include creating a pressure differential in a forward portion of the gas flowpath with respect to an aft portion of the gas flowpath to generate a counterflow of the detergent therethrough. The flow and counterflow of the detergent through the gas flowpath interact with components of the turbine engine having foreign material thereon to at least partially remove the foreign material therefrom.

Abstract: A method of cleaning a component within a turbine that includes disassembling the turbine engine to provide a flow path to an interior passageway of the component from an access point. The component has coked hydrocarbons formed thereon. The method further includes discharging a flow of cleaning solution towards the interior passageway from the access point, wherein the cleaning solution is configured to remove the coked hydrocarbons from the component.

Abstract: The present disclosure is directed to a method for in-situ cleaning one or more components of a gas turbine engine using an abrasive gel detergent. More specifically, the gel detergent includes a plurality of abrasive particles suspended in a gel composition. Further, the abrasive particles include organic material. Moreover, the gel composition is formed of a mixture of detergent particles dissolved in a gel reactant. Thus, the method includes injecting the gel detergent into at least a portion of the gas turbine engine at a predetermined pressure. In addition, the method includes allowing the gel detergent to flow across or within one or more of the components of the gas turbine engine so as to clean one or more of the components.

Abstract: A wash system for a gas turbine engine includes a foam generating device configured for receiving and aerating a flow of wash fluid to generate a flow of foamed wash fluid having particular foam characteristics. The flow of foamed wash fluid passes through a distribution manifold where it is selectively directed through a plurality of wash lines to desired portions of the gas turbine engine. The wash system further includes a controller configured for manipulating the foam characteristics of the flow of foamed wash fluid and using the distribution manifold to selectively direct the flow of foamed wash fluid to desired portions of the gas turbine engine for optimal cleaning and improved engine efficiency.
