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.

Various embodiments herein pertain to apparatus and methods that utilize the water and existing chemicals to generate a foam. The foam can be introduced at that gas-path entrance of the equipment, where it contacts the stages and internal surfaces, to contact, scrub, carry, and remove fouling away from equipment to restore performance. Various embodiments include operating a gas turbine engine; measuring the performance of the engine during operation; determining that the engine should be foam washed based on the measurements; mixing pressurized gas with pressurized liquid and creating a supply of foam; and streaming the supply of foam into the engine.

An aircraft comprising a turbine engine, an atomizer, a reservoir, a conduit connecting the reservoir to the atomizer, and a unit for controlling the flow of liquid in the atomizer. The turbine engine, the atomizer, the reservoir, the conduit and the control unit are fixed to the aircraft. This allows cleaning in flight of at least some parts of the turbine engine.

A piping system of a steam turbine plant is provided with: steam piping connected to a steam turbine; bypass piping which branches from the steam piping at a branching portion and which is connected to a condenser; a steam check valve provided between the branching portion of the steam piping and the steam turbine; and a turbine bypass valve provided in the bypass piping. A piping system cleaning method includes the steps of: connecting at least one valve of the steam check valve and the turbine bypass valve and a connecting portion provided between the turbine bypass valve of the bypass piping and the condenser, by using temporary piping having a foreign matter collecting portion; closing a flow path on the outlet side of the valve; cleaning the steam piping by supplying steam to the steam piping; and sending the steam to the condenser through the temporary piping.

An engine component is configured with a component fluid passage and a receptacle. The component fluid passage extends within the engine component to the receptacle. The receptacle extends through the engine component between a receptacle first end and a receptacle second end. A fluid diverter is configured with a diverter fluid passage and a port. The fluid diverter extends between a diverter first end and a diverter second end. The diverter fluid passage extends partially into the fluid diverter from the diverter first end. The fluid diverter is mated with the receptacle. The diverter first end is disposed at the receptacle first end. The diverter plugs a portion of the receptacle at the diverter second end. The port fluidly couples the component fluid passage to the diverter fluid passage. Fluid is directed through the component fluid passage into the diverter fluid passage to remove debris from the engine component.

A turbine component surface treatment process includes passing a UV-curable maskant through one or more fluid flow passages, wherein at least a portion of the UV-curable maskant exits the one or more fluid flow passages at an exterior surface of the turbine component, applying a UV light to the exterior surface of the turbine component, wherein the UV light cures at least a portion of the UV-curable maskant exiting the one or more fluid flow passages, and, treating the exterior surface with a treatment material, wherein the portion of the UV-curable maskant cured by the UV light substantially blocks the treatment material from entering the one or more fluid flow passages.

A system includes a power generation system and a controller that controls the power generation system. The controller includes a processor that generates a model of the power generation system that estimates a value for a first parameter of the power generation system. The processor also receives a measured value of the first parameter. The processor further adjusts a correction factor of the model such that the estimated value of the first parameter output by the model is approximately equal to the measured value of the first parameter. The processor also generates a transfer function that represents the correction factor as a function of a second parameter of the power generation system. The processor further displays the transfer function along with one or more previously generated transfer functions to quantify degradation of the power generation system.

A turbine engine fleet wash management system is configured to electronically communicate with a turbine engine system, a fleet management service, and a cleaning management service. The turbine engine fleet wash system causes a cleaning of a turbine engine to occur based on information received from the turbine engine system and other sources. The turbine engine fleet wash management system includes a cleaning schedule optimizer that generates a cleaning schedule based on engine health monitoring data, engine operation data, maintenance schedules for the turbine engine, and cleaning regimen data. The cleaning schedule optimizer estimates turbine engine performance improvements based on the selected cleaning regimen, and calculating an estimate of carbon credits earned based on the predicted improvement in turbine engine performance.

An inflatable device equipped with a guiding mechanism and methods of installing the inflatable device to form a temporary barrier within a gas turbine engine are provided. In one aspect, an inflatable device includes a backbone and an inflatable bladder connected thereto. The backbone is formed of a flexible and inextensible material. The inflatable bladder is formed of an expandable material. To install the inflatable device within an annular chamber of a gas turbine engine, the backbone is inserted into a first access port of the engine and is moved circumferentially around the annulus of the chamber. The backbone is retrieved through a second access port. The inflatable bladder is moved into position within the chamber by pushing the backbone into the first access port and/or pulling the backbone out of the second access port. When positioned in place, the inflatable bladder is inflated to form an annular seal.

An aircraft propulsion assembly includes a power unit, a nacelle positioned around the power unit, and a cleaning device configured to remove insect residue and in order to maintain optimal aerodynamic characteristics. This cleaning device is configured to spread at least a cleaning liquid over an exterior and forward region of the air intake of the nacelle, the cleaning liquid being entrained by a high-speed airflow generated by the power unit and acting as a high-pressure water jet to encourage the removal of the insect residue.
