  • 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.

  • Publication number: 20090026291
    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: 6736635
    Abstract: The present invention provides a burner for use in a combustion-type waste gas treatment system for combusting waste gases emitted from semiconductor manufacturing system, particularly, a deposition gas containing SiH4 and a halogen-base gas, simultaneously at a high efficiency of destruction, making it difficult for a powder of SiO2 to be attached and deposited, performing a low-NOx combustion, and maintaining a desired level of safety. The combustion-type waste gas treatment system has a flame stabilizing zone (15), which is open toward a combustion chamber (11), surrounded by a peripheral wall (12), and closed by a plate (14) remotely from the combustion chamber. A waste gas, an auxiliary combustible agent, and air are introduced into and mixed with each other in the flame stabilizing zone (15), and the mixed gases are ejected toward the combustion chamber (11) perpendicularly to the plate (14).

  • Patent number: 6663021
    Abstract: A convergent type of spray gun is made portable by miniaturizing the components with the addition of a double tube, fluid tip and air cap for defining the discharge nozzle for the liquid resin and atomizing air. The dry powdered nozzle is likewise miniaturized and is adapted to fit over the double tube, fluid tip and air cap arrangement by including a sleeve disposed therebetween. The main body is configured in either an L-shape or straight-through configuration. Although the component parts are miniaturized, the spray gun is capable of flowing coating mixture at the same rate as the larger version convergent spray gun.

  • Patent number: 6663016
    Abstract: A melter, mixer and applicator system for applying coating or sealing compositions is disclosed. A diesel engine provides the motive force necessary to operate many of the components of the system. A tank surrounded by an internal heating system is provided for melting a first material. An insulated cabinet is provided and heated from heat generated by the internal heating system. The plumbing configuration is disposed within the heated cabinet for mixing the material heated within the tank with an additional material fed to the plumbing configuration by a proportioner pump. The output of this mixture serves as one of the inputs to the applicator. The other input to the applicator is another material fed directly from the proportioner pump. The proportioner, preferably provides the two materials running through it in a predetermined ratio amount with respect to each other.

  • Patent number: 6547163
    Abstract: A hybrid atomizing fuel nozzle includes a stem with primary and secondary fuel circuits. A nozzle assembly fixed at the downstream end of the stem includes primary and secondary nozzle portions. A shroud and swirler assembly surrounds the nozzle assembly, and includes an annular body with a prefilmer surface. A radial inflow swirler in the annular body directs a first swirling air flow radially inward toward the secondary nozzle portion. An outer air swirler disposed in surrounding relation to the annular body provides a converging second swirling air flow downstream of the prefilmer surface. Discrete fuel passages direct fuel streams outward and downstream toward and against the prefilmer surface. The fuel passes through the first air flow and is evenly distributed across the prefilmer surface in a thin continuous sheet. The first and second air flows then cause the sheet to form a conical spray of atomized fuel.
