  • Patent number: 10578303
    Abstract: An inlet assembly for a an abatement burner includes: an inlet conduit operable to convey an effluent gas stream to be treated from an inlet aperture via a bore to an outlet aperture for treatment; and a lance conduit operable to convey a fuel gas from a gas inlet aperture via a gas bore to a gas outlet aperture positioned within the bore for mixing with the effluent gas stream, a cross-sectional area of the gas bore increasing towards the gas outlet aperture. In this way, the expansion caused by the increasing cross-sectional area of the gas bore enhances the mixing of the fuel gas with the effluent gas stream which provides for improved destruction and removal efficiencies (DRE), which enables the inlet assembly to be operated with reduced quantities of fuel gas, while still maintaining required levels of DRE.

  • Patent number: 10166558
    Abstract: The invention relates to a cooling device for a spraying nozzle, in particular for cold gas spraying, and to a spraying nozzle assembly equipped with such a cooling device. The spraying nozzle is surrounded by an enclosure forming the cooling device, wherein it is provided according to the invention that a cooling line within the enclosure forms a closed system which can be supplied with a cooling medium by way of an inlet and an outlet. The cooling medium therefore advantageously does not come into contact with the spraying nozzle, which is inserted into a receiving opening in the enclosure by means of a loose fit. The closure may also advantageously taper conically towards the mouth of the spraying nozzle, and therefore coatings can also be applied to difficultly accessible components by means of the spraying nozzle assembly according to the invention.

  • Patent number: 9751146
    Abstract: To achieve an improvement of heat exchanger effectiveness (heat transfer rate) without any increase of a fan motor output. The gas heated by the heating units or the gas cooled down by the cooling units is sent to the blowing nozzles 2 by a fan. Then, the blowing nozzles 2 blow the gas sent by the fan through their outlets. Each of the outlets has a non-circular planar shape with a projection portion thereof being projected inwardly. This allows a shape of the gas in cross section perpendicular to a direction where the gas is blown through the outlet of each of the blowing nozzles 2 to be changed by the projection portion with time (switching phenomenon). Such a switching phenomenon enables to be increased the heat exchanger effectiveness (heat transfer rate) on the printed board even if any output of the fan motor for rotating the fan does not increase.

    Abstract: A temperature controlled showerhead for chemical vapor deposition (CVD) chambers enhances heat dissipation to enable accurate temperature control with an electric heater. Heat dissipates by conduction through a showerhead stem and fluid passageway and radiation from a back plate. A temperature control system includes one or more temperature controlled showerheads in a CVD chamber with fluid passageways serially connected to a heat exchanger.

  • Publication number: 20140054394
    Abstract: A reductant delivery unit (RDU) delivers supplied reductant (aqueous urea solution) to the engine exhaust system. The delivered reductant is transformed into ammonia which then reacts with the exhaust oxides of nitrogen in a catalytic environment to produce nitrogen and H20. The reductant must be metered to coincide with the amount of NOx present in the exhaust, and also present sufficient spray quality of the delivered fluid to promote good mixing of the ammonia with the exhaust gas. The RDU is a liquid-cooled, making the RDU suitable for very high temperature environment applications.

  • Patent number: 8596556
    Abstract: The present invention provides additional cooling assistance for automotive heat exchanging systems used for the cooling of liquids or air needed for engine operations. This operating system utilizes a liquid reservoir, an electric pump, a liquid transfer hose housing a directional flow valve, a spray nozzle, a liquid recycling tray mounted below the heat exchanger, a recycling liquid return hose, an electrical timed pulse relay circuit incorporated into a remotely mounted electrical on and off switch assembly, or the system can be automated with the incorporation of an adjustable thermostatic control sensor circuit. Under extreme operating conditions, a vehicle's engine can reach undesirable operating temperatures and when providing a mist of liquid to the frontal area of the heat exchanger, helps to stabilize or drop the engine's operating temperatures.
