  • Publication number: 20180258787
    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.

  • Publication number: 20180250688
    Abstract: An atomizing spray device includes a housing having inlets that receive a first fluid and a slurry of ceramic particles and a second fluid. The inlets are fluidly coupled with outlets by an interior chamber that mixes the first fluid with the slurry to form a primary mixture of the first fluid and first atomized droplets of the slurry. A first outlet on a first side of the housing and a second outlet on the first side of the housing are shaped to change the primary mixture to form a secondary mixture of the first fluid and second atomized droplets of the slurry. The first outlet sprays the secondary mixture onto a first surface as a first layer of coating and the second outlet sprays the secondary mixture onto the first surface as a second layer of coating while the housing moves in a direction along the first surface.

  • Patent number: 10018113
    Abstract: A cleaning system and method use an ultrasound probe, a coupling mechanism, and a controller to clean equipment of a vehicle system. The ultrasound probe enters into an engine. The ultrasound probe emits ultrasound pulses and the coupling mechanism provides an ultrasound coupling medium between the ultrasound probe and one or more components of the engine. The controller drives the ultrasound probe to deliver the ultrasound pulse through the coupling medium to a surface of the one or more components of the engine. The ultrasound probe delivers the ultrasound pulse to remove deposits from the one or more components of the engine.

  • Publication number: 20180154381
    Abstract: An atomizing spray device includes a housing having plural inlets and one or more outlets fluidly coupled with each other by an interior chamber. The inlets include a first inlet shaped to receive a first fluid and a second inlet shaped to receive a slurry of ceramic particles and a second fluid. The interior chamber in the housing is shaped to mix the first fluid received via the first inlet with the slurry received via the second inlet inside the housing to form a mixture in a location between the inlets and the one or more outlets. The interior chamber in the housing also is shaped to direct the mixture formed inside the housing as droplets outside of the housing via the one or more outlets such that, based on a discharged amount of the first fluid in the droplets, the first fluid promotes evaporation of the second fluid as the droplets traverse from the housing toward a surface of a component.
