In order to maintain a minimum exhaust discharge velocity to ensure adequate plume height, an axially-extendable, upwardly tapered flow-impinging pod within the nozzle creates a variable annular nozzle outlet opening. As opposed to a circumferentially-constricted outlet opening, the variable annular outlet produces a uniform discharge velocity profile conducive to the induction of ambient air through a windband.

The hub is configured with identical vanes arrayed uniformly about the central axis and specially shaped to accomplish a set of desired flow path objectives. The vanes are generally tapered such that their cross-sectional shape evolves from predominantly solid material in area at the top of the hub to predominantly open area at the bottom of the hub, where the flow paths proceed downwardly into a tubular exhaust passageway. The entry to the exhaust passageway may take the form of effectively a hollow portion of the shaft in the exhaust region, which may be supported from the enclosure by a bearing set. The central opening in each disk, and thus in the stack, and in the periphery of the hub are both configured with a complementary mating interface pattern: e.g.

  • Patent number: 8220098
    Abstract: A portable cleaning apparatus includes a handle (11) and a wheel (13) rotatably mounted to the handle and the wheel having a plurality of scrubbing elements (74). Pressurized fluid enters the apparatus and a fluid flow director (16) delivers the fluid to the scrubbing elements to rotate the wheel. The scrubbing elements can be secured to the wheel to limit pivoting movement of the scrubbing elements in a direction of rotation of the wheel while permitting greater pivoting movement of the scrubbing elements in direction opposite the direction of rotation of the wheel. Different types of treatment material dispensing systems (100) are operable position a flow director to spin a dispenser of treatment material, or to position a dispenser in the rotational path of the scrubbing elements, to apply treatment material to the scrubbing elements.

  • Publication number: 20120177489
    Abstract: A sealing element is provided for sealing a leak path between a radial outer platform of a turbine nozzle and a carrier ring for carrying said radial outer platform. The carrier ring has an axially facing carrier ring surface and the radial outer platform has an axially facing platform surface. The carrier ring surface forms a first sealing surface and the platform surface forming a second sealing surface. The first and second sealing surfaces is aligned in a plane with a radial gap between them. The sealing element includes a leaf seal adapted to cover the gap between the first and second sealing surfaces, and an impingement plate for allowing impingement cooling of a radial outer surface of the radial outer platform. The impingement plate is adapted to be fixed to the turbine nozzle. The sealing element may be part of a nozzle arrangement of a gas turbine.

    Abstract: An apparatus and method for treating sewage The apparatus receives sewage at a receiving compartment and separates solids from liquids at the receiving compartment. The solids can be extracted from the receiving compartment by an auger. The liquid sewage flows through a series of treatment compartment containing rotating biological contactor discs for treatment by these rotating biological contactor discs. The rotating biological contactor discs are secured to a rotating shaft. The rotating shaft and the auger are powered by a quasi-submerged turbine displaced by a flow of air.

  • Patent number: 8197200
    Abstract: A moving-air energy recovery system including an air horn having serially disposed segments of differing flare rates, which intercepts a large area of moving air to channel and transform the flow of moving air into a more concentrated, higher velocity of air flow. This higher velocity air flow is applied to turbine vanes which are connected to an armature that provides a mechanical energy output from the incident air flow on a rotating shaft. In one embodiment, the shaft is connected to a electric generator to generate electric power, which may be applied to stationary applications such as emergency home power, and to mobile applications such as augmenting automobile propulsion.

  • Publication number: 20120141249
    Abstract: Systems and methods configured to control ambient fluid flow for increased energy extraction using a turbine are disclosed. In various examples, a system can include a convergent nozzle configured to receive and accelerate an ambient flow of fluid and a turbine including one or more rotor blades. The convergent nozzle can include a configuration having a ratio of a nozzle inlet area to a nozzle outlet area between about 1.5:1 to about 10:1, inclusive. An interior nozzle surface can include one or more contours aligned with a direction of the ambient flow of fluid. The convergent nozzle can include apertures in a region near a nozzle outlet. The apertures can be selectively controlled to draw additional fluid flow into the accelerated flow to avoid excessive stress on turbine components. The rotor blades can have a length equal to or slightly greater than a radius of the nozzle outlet.
