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.

Wands are used as parts of cleaning systems to conduct cleaning agents into gas turbine engine cores. Wands according to the present disclosure include inlet assemblies adapted to connect to cleaning agents, dispensers adapted to discharge cleaners into gas turbine engines, and conduits that extend from the inlet assemblies to the dispensers.

A vehicle wash system includes a wash package selection zone where a vehicle operator is presented with a plurality of different vehicle wash packages. Each of the vehicle wash packages has an associated unique color identifier. The system includes a controller configured to receive a selection from the vehicle operator of one of the plurality of different vehicle wash packages. The system includes a vehicle treatment zone, including at least one illumination element associated therewith. The at least one illumination element is in communication with the controller. The controller is configured to emit light from the at least one illumination element in a color that corresponds to the color identifier of the vehicle package selected by the vehicle operator.

The invention discloses cleaning compositions which employ a synergistic combination of an ester solvent, preferably a fatty acid methyl ester in combination with one or more linear alkyl amines. The alkyl amines act as to remove and suspend organic oils which have been burnt or adhered to a surface with heat and may even be used alone as a soil removal agent. The cleaning compositions have particular use in cleaning of distillation towers associated with biofuel, and vegetable oil refining, but also find use in cleaning ovens, food cooking surfaces and even dry cleaning.

A high-pressure cleaning system is provided, including a high-pressure cleaning apparatus having a high-pressure pump for increasing the pressure of a cleaning liquid, and two or more discharge units for discharging the cleaning liquid, which are different and can be selectively brought into fluid communication with a pump outlet of the high-pressure pump, wherein the discharge units are connectable to an operating unit or wherein an operating unit is arranged on at least one discharge unit. The high-pressure cleaning system includes an input unit via which at least one output parameter is predeterminable by a user and is adjustable by way of a control unit coupled to the input unit. The high-pressure cleaning system includes an output unit coupled to the control unit and capable of providing an indication depending on the predetermination made by the user, said indication including a recommendation of at least one discharge unit.

A foam generating device for a high-pressure water gun has a supporting body defining part of a conduit, which extends along an axis and has a mixing chamber communicating with a lower inlet, and subject, in use, to a vacuum to aspirate a liquid from said lower inlet; the device has a first sleeve which is fitted around one end of the supporting body, is axially fixed, is rotatable and is provided with an end portion carrying a nozzle; such a nozzle defines the outlet of the conduit and is adjustable so as to vary the outgoing flow type between a fan-like jet and a solid stream jet; the device has, in addition, a second sleeve which is coupled to the first sleeve in a fixed axial position and in a rotatable manner and is provided with cams to adjust the nozzle in response to a rotation of the second sleeve with respect to the first sleeve.

In a chemical mechanical polishing system, a platen shield cleaning assembly is installed on a rotatable platen in a gap between the rotatable platen and a platen shield. The assembly includes a sponge holder attached to the platen and a sponge. The sponge is held by the sponge holder such that an outer surface of the sponge is pressed against an inner surface of the platen shield.

A machine is cleaned by directing a foam detergent into the machine to remove contaminants from inside the machine. An effluent portion of the foam detergent exits from the machine with some of the contaminants. One or more of a turbidity, a salinity, an amount of total dissolved solids, or a concentration the contaminants in the effluent is measured. A cleaning time period during which the foam detergent is to be directed into the machine is determined based on the turbidity, the salinity, the amount of total dissolved solids, and/or the contaminant concentration that is measured from the effluent. The foam detergent continues to be directed into the machine during the cleaning time period, and the flow of the foam detergent into the machine is terminated on expiration of the time period.
