    Abstract: Disclosed herein is a nozzle tip that atomizes a liquid entering a vessel or reaction zone that contains circulating fluidized particulates where the nozzle tip comprises a first elongated slot that intersects with a second elongated slot to define a single orifice. The first elongated slot may have members protruding into it and the slots may intersect substantially orthogonally and bisect each other. The length of the minor axis of the first slot ranges form about 5% to about 50% of the length of the major axis of the first slot and the length of the minor axis of the second slot ranges form about 1% to about 10 % or the major axis of the second slot. This nozzle tip affords erosion reduction caused by the circulating fluidized particulates and therefore provides longer operational lifetimes for the nozzle tip.

  • Patent number: 6886640
    Abstract: The invention is aimed at generating a finely dispersed gas-and-drop flow with its cross-section in the shape of an ellipse and uniform intensity distribution. A fluid spray nozzle is built in the form of a body (1) with two coaxial channels (2) of the same cross-section designed for head liquid supply and a nozzle having a shape of a conical diffuser (3). The diffuser (3) is oriented transverse to the channels, the area of its inlet orifice not exceeding the total cross-section area of the channels. The fire extinguisher fitted with a fluid spray nozzle comprises a liquid vessel (4) for fire extinguishing, a liquid expulsion system, a pipeline (11), connecting a liquid cavity (5) of the vessel (4) to a spray nozzle and at least one valve or a regulator (8) to control the liquid supply to the spray nozzle.

  • Patent number: 6742730
    Abstract: A spray nozzle for producing an asymmetrically distributed fluid discharge pattern such as for use in a container coating application is provided. The spray nozzles includes a body portion having an internal fluid passageway which terminates in a substantially hemispherical dome shaped end wall. A discharge orifice is provided in the end wall which is produced by superimposing on each other an approximately round opening and an elongated opening having opposed rounded ends. The round opening and the elongated opening defining respective edges of the discharge orifice which extend at different angles relative to a longitudinal axis of the fluid passageway. The resulting orifice produces a fluid discharge pattern wherein the amount of fluid discharged tapers in a continuous, non-linear manner from the location of maximum discharge to points of minimum flow at either end of the discharge pattern.

  • Patent number: 6625971
    Abstract: A fuel nozzle, comprising an inlet for receiving fuel and an outlet for discharging fuel. The outlet intersects a longitudinal centerline of the nozzle and produces a skewed spray pattern. A fuel injector having a fuel nozzle outlet such that a fluid discharged from a swirler produces a crescent-shaped spray pattern in the fuel. A burner section of a gas turbine engine comprising a combustion chamber and fuel injectors. At least one of the fuel injectors produces a skewed flame pattern in the combustion chamber that overlaps with a flame pattern from an adjacent fuel injector. A method of improving stability of a flame in a burner section of a gas turbine engine in which at least one of the fuel injectors produces a skewed flame pattern in the burner section to create a fuel non-uniformity, the flame pattern also overlapping with an adjacent flame pattern.

    Abstract: At a time of forming lip portions 9e, 9f in upper and lower edge portions of an injection port 9d in a protruding manner, a nozzle for injecting a washer fluid of a washer fluid injection apparatus in a diffusion manner is structured such that a step surface 9i is formed on an inner side surface 9h such that protruding amounts of the lip portions 9e, 9f are set to the same size, a protruding tip portion in a washer fluid injection side of the lower lip portion 9f is positioned in a lower side than a lower side edge portion of the injection port 9d. Accordingly, it is possible to make the injected washer fluid hard to be affected by an air flow during traveling.

  • Patent number: 6612509
    Abstract: The present invention relates to a nozzle intended for the application of fluid materials, which at a front end thereof has an aperture opening into a slot. A central portion of the slot is functioning to release most of the material straight ahead. Furthermore, the slot has side portions functioning to release material in sideway directions. In a preferred embodiment, the front end is shaped like a truncated cone with a flat top, in which the slot is formed. The slot is thus divided into three straight portions with the central portion in the flat top and the angle of the side portions defined by the top angle of said cone. Under certain conditions, the jets of material released from the various portions are held together by a surface tension. As most of the material is released from the central portion, the jets from the angled side portions will be deflected towards the center jet, resulting in a jet with a relatively even width, and a resultant coating being thickest in the middle.

  • Patent number: 6572033
    Abstract: A module or dispenser for dispensing at least one liquid filament onto a moving substrate includes a nozzle body having a liquid supply port, a liquid discharge portion or end, and a liquid discharge passage having an orifice in fluid communication with the liquid supply port. The liquid discharge passage extends along an axis and the opening is shaped asymmetrically about the axis to provide a controlled directional movement of the liquid filament in a desired direction. The asymmetric shape may be formed by a notch or a chamfer or a stepped portion intersecting with the liquid discharge passage, or combinations of these features, or in other manners.
