  • Patent number: 8302884
    Abstract: A cross-flow injector is used to introduce fluids into a chemical vapor deposition process chamber separately and simultaneously for efficiently atomizing and vaporizing the fluids. The cross-flow injector consists of a three port cavity having an inlet nozzle, a throat region, and an exit nozzle. The injector cavity is defined by the tapering of the inlet and exit nozzles to the smaller diameter of the throat region. The tapering allows for pressure differentials at the inlet, throat, and exit regions, and assures the inlet pressure being much greater than the exit region. The throat region consists of additional apertures for injecting dopants and precursors within the fluid flow. The pressure differential at the throat region atomizes and vaporizes the injected dopant and precursor fluids. In a second embodiment, the injector cavity consists of two ports, having an inlet nozzle and a throat region.

    Abstract: Presented is a pre-filming fuel nozzle that is readily manufacturable and consists of a fuel injector, a nozzle insert that fits over the fuel injector outlet, and a housing that generally encloses the fuel injector and nozzle insert. The housing has an atomizing lip, a fuel inlet passage, and an air passage. The nozzle insert has openings near the fuel injector that allows air to flow into the insert. During operation, the fuel injector impinges fuel on an inner surface of the insert and is pulled towards the atomizing lip from air flow through the insert. The air flow through the insert and air flow through the housing join at the atomizing lip, resulting in air flows shearing fuel droplets off of the atomizing lip. The nozzle may have swirler means such as a swirler fin and/or swirler passages on the insert to aid in swirling the air flow.

    Abstract: A self-contained, hand-held spray dispensing device includes an internal source of pressurized fluid that exerts a motive force on a pair of liquid ejecting elements to cause each to eject a liquid into a discharge line. The liquids remain separated until each exits its discharge port. A pressurized fluid is directed over the outlet ends of the discharge line beginning before a flow interrupter in the discharge line is opened to permit flow therethrough and ceasing after liquid flow is terminated. The pressurized fluid flow over the outlet of the discharge line aerosolizes liquids emanating from the outlet ends. Each liquid ejecting element takes the form of a piston disposed within a cylinder. The pistons responds to pressurized fluid imposed directly thereon from the source to generate the motive force on the ejecting element.

The system includes a power plant for powering the compressed air foam and high pressure liquid sub-systems of the system. The high pressure sub-system further includes a boiler for heating the liquid to a temperature above ambient temperature. The boiler and power plant may use the same type of fuel for decreasing the number of fuel supplies to the system. In addition, the power plant drives an air compressor for providing compressed air for powering the compressed air foam sub-system. The power plant further drives a high pressure water pump for pressurizing the water for the high pressure sub-system.

  • Patent number: 7905428
    Abstract: A sprayer has a sprayer outlet and a pressurizable reservoir adapted to contain a fluid. The reservoir has an air-pressure outlet and a reservoir outlet, the reservoir outlet being in fluid connection with the sprayer outlet. Detachable, pressurizable tanks are adapted to contain a chemical, each tank having a chemical outlet and an air-pressure inlet. Each air-pressure inlet is in fluid connection with the air-pressure outlet of the reservoir for equalizing air pressure between the reservoir and each tank. A switch is adjustable between a plurality of settings for causing at least one of the chemical outlets to be in fluid connection with the sprayer outlet. A ratio valve is provided for selecting a fluid flow rate out of the selected outlet. Fluids flowing into the sprayer outlet from the outlets are mixed together prior to discharge from the sprayer outlet.

  • Patent number: 7681808
    Abstract: A spray device includes an opening gap between a needle-shaped needle tip and a first nozzle hole. The gap is adjusted by a very tiny amount by a needle movement amount adjustment device, and liquid oozes from the first nozzle hole along the needle tip part. The liquid is formed into tiny particles by a first atomization compressed gas flowing through the first atomization compressed gas passage and is exhausted from a second nozzle hole. The exhaust flow passes through a third nozzle hole and is exhausted. The third nozzle's second atomization/eddy flow formation compressed gas collides with this exhaust flow, so the exhaust flow is made into even smaller particles, and swirls and disperses, and is applied to the coated object.

  • Patent number: 7670440
    Abstract: A nozzle (54) for cleaning a gas turbine unit (1) during operation. The invention further relates to a method for washing a gas turbine unit (1) during operation. The nozzle (54) is arranged to atomize a wash liquid in the air stream in an air intake (2) of the gas turbine unit (1) and comprises a nozzle body (40) comprising an intake end (41) for intake of said wash liquid and outlet end (55) for exit of said wash liquid. The nozzle further comprises a number of orifices (42, 46; 42, 46, 60) that are connected to the outlet end (55) and respective orifice (42, 46; 42, 46, 60) is arranged at a suitable distance from a center axis (49) of said nozzle body (40), whereby the local density of the injected wash liquid in a desired area can be increased with preserved droplet size and thereby the efficiency of the cleaning process can be significantly improved at the same time as the risk for damaging the components in the gas turbine unit is significantly reduced.

  • Patent number: 7648335
    Abstract: In the method for interspersing a gas flow with liquid droplets, the liquid droplets are injected in a liquid injection plane into the gas flow, characterized in that an auxiliary gas is simultaneously injected with the liquid droplets into the gas flow. The injection speed of the auxiliary gas is larger than the injection speed of the liquid droplets so that the injected auxiliary gas stabilizes the injected liquid droplets with respect to trajectory and size, partly shields them from the gas flow and/or entrains them into the gas flow. By way of this one achieves an improved control of the spatial distribution of the liquid droplets and their size distribution. The liquid droplets penetrate the gas flow more efficiently than without an auxiliary gas. A preferred use is the online wet-cleaning of a gas turbine compressor.

  • Publication number: 20090108105
    Abstract: In order to allow dual fuel operation, that is to say gas and liquid fuel, a fuel injection arrangement and an assembly are provided in which an injection conduit provides constriction to an airflow towards an outlet. In an assembly a plurality of arrangements including liquid fuel jets are arranged to such that through high angle incidents by the airflow appropriate vaporisation and droplet formation is achieved for a fuel/air mixture combustible in a combustor of a turbine engine. At low liquid fuel flow rates below a pre-determined level the liquid fuel is atomised and entrained by the airflow. At high liquid fuel flow rates the fuel splash impinges upon a wash surface to develop a wash film which is again vaporised and atomised about an edge for a fuel/air mixture capable of combustion.
