A hose conducts high-temperature steam combined with cleaning solution in a cleaning operation. The hose comprises an external liner, an intermediate conduit, and an internal liner. The external liner comprises first braiding and is disposed along a longitudinal length of the hose. The intermediate conduit is disposed in the external liner along the longitudinal length of the hose. The intermediate conduit has a plurality of corrugations disposed laterally in the tubular wall of the intermediate conduit. The internal liner comprises second braiding and is disposed in the intermediate conduit along the longitudinal length of the hose. The internal liner provided a full bore for the hose configured to conduct the high temperature steam combined with the cleaning solution in a volatilized mixture.

Methods and apparatus are provided for washing pipette tips, including the inside and outside of the pipette tip. Pipette wash devices comprise a main body comprising a wash chamber, a liquid channel, a gas channel, and a nozzle cavity, and a nozzle for providing a washing mist is positioned in the nozzle cavity and fluidically connected with the liquid channel and the gas channel. Methods of washing a pipette tip include inserting a pipette tip in a wash chamber; spraying a mist on an outside surface of the pipette tip; and blowing pressurized air or inert gas on the outside surface of the pipette tip, thereby washing and drying the pipette. Methods of washing a pipette tip also include passing one or more series of liquid slugs separated by gaseous gaps through the inside of the pipette tip.

System and method for removing scale of a sewer pipe using microbial mist type spray, the system including a microbe storage tank to store liquid microbes; a chamber connected with the microbe storage tank through an injection pipe and supplied with a determined, metered amount of liquid microbes, if needing to spray liquid microbes into the sewer pipe; a metering pump provided on one side of the injection pipe, to supply power for injecting a metered amount of liquid microbes into the chamber; an air tank to store compressed air; a supply pipe to supply compressed air into the chamber when the liquid microbes are sprayed; a supply tube to allow liquid microbes having air cavities resulting from supply of the compressed air to flow; and a spray nozzle provided at an end of the supply tube, to spray liquid microbes in a mist form into the sewer pipe.

A method cleans surfaces in an internal volume of an aircraft component through which a medium flows. The method includes: connecting the internal volume to be cleaned to a steam generator; generating a cleaning steam having a predetermined vapour pressure and temperature by the steam generator; applying the cleaning steam to the surfaces to be cleaned in the internal volume; maintaining the vapour pressure and the temperature within the internal volume for the duration of a predetermined condensation time; generating a pressure drop in the internal volume of the aircraft component, in order to vaporise the portion of the cleaning steam that condensed during the condensation time; and removing the cleaning steam from the internal volume via a discharge device.

The present invention relates to a method of rapidly decontaminating and making safe for entry, hydrocarbon contaminated equipment by sequencing a cleaning mist or foam, an encapsulating mist or foam and a dry carrier gas.

A vehicular cleaning system performs cleaning to remove foreign matter attached to a cleaning target in a vehicle. The vehicular cleaning system includes: an air pump driven to generate an air spray; a washer pump driven to supply a washing solution; a spray nozzle which blows an air-liquid mixed fluid, obtained by mixing the air spray and the washing solution, onto the cleaning target; a washing solution storage unit configured to store the washing solution supplied from the washer pump, and to be capable of discharging the stored washing solution when the washing solution is to be mixed with the air spray; and a mixing and outputting unit configured to blow the air-liquid mixed fluid, obtained by mixing the air spray and the washing solution introduced from the washing solution storage unit, from the spray nozzle toward the cleaning target.

Systems and methods for cleaning deposits from a component of an assembled, on-wing gas turbine engine are provided. Accordingly, the method includes operably coupling a delivery assembly to an annular inlet of a core gas turbine engine. A portion of cleaning fluid is atomized with the delivery assembly to develop a cleaning mist having a plurality of atomized droplets. The atomized droplets are suspended within any path of the core gas turbine engine from the annular inlet to an axial position downstream of a compressor of the core gas turbine engine. A portion of the cleaning mist is impacted or precipitated onto the component so as to wet the component, and a portion of the deposits on the component is dissolved by the cleaning mist.

The invention relates to a method for producing a gaseous medium comprising steam, said steam being produced from a first fluid medium separated from the exhaust gas from combustion of a fuel in a steam generating step, said fuel being provided for burning for providing energy for heating said first fluid medium, comprising the steps of mixing the steam thus produced with exhaust gas from combustion of said fuel; and supplying at least one chemical substance different from air and water to said steam and exhaust gas mixture. The invention also relates to a device for producing a gaseous medium comprising steam.
