  • Patent number: 9845780
    Abstract: Methods and systems are provided for direct fuel injection. In one example, a fuel injector system includes a needle, a plurality of tangential fins coupled to a nozzle end of the needle, an actuator coupled to the needle, and a controller storing non-transitory instructions that when executed cause the controller to, responsive to a command to inject fuel, activate the actuator to push the needle in a downward direction by an amount based on one or more operating parameters. In this way, the fuel injector may inject fuel with a cone shaped spray pattern, reducing the spray penetration of the injected fuel.

  • Patent number: 9649594
    Abstract: A furnace/boiler incorporates a dual injection grid arrangement as per present disclosure. The furnace includes an enclosure having burners projecting through walls of the lower half of the enclosure. The burners inject and ignite a supply of fuel and primary air. The combustion reaction takes place in a combustion chamber. The enclosure walls carry steam generating tubes which absorb radiative heat from the combustion flame to produce steam. The heat is also utilized by radiative/convective super-heater and reheater elements where steam flowing through the radiative/convective super-heater and reheater elements is superheated by the hot gas products of the combustion process. The hot gas combustion products are referred to as the exhaust or flue gas. The combustion products exit the combustion chamber at boiler nose and enter in the boiler/furnace area. The present grid arrangement inject chemicals to control the creating reactants particularly NOx and SO3 emissions.

  • Patent number: 9435537
    Abstract: A combustion system premixer includes one or more streamwise vortex generators configured to passively redirect surrounding high velocity air into at least one of wake and vortex regions within a combustion system fuel nozzle in response to air passing through the premixer. The streamwise vortex generators operate to minimize turbulent flow structures, thus improving air/fuel mixing, and enhancing resistance to flame-holding and flash-back within the premixer.

  • Publication number: 20150099232
    Abstract: A burner includes a cylindrical tube that terminates in a burner discharge end. An annular disk, affixed to the discharge end, defines a hole. An oxidizer intake delivers oxidizer into the tube. A fuel nozzle delivers fuel into the tube. A cylindrical slotted member has an interrupted outer surface and is disposed within a portion of the tube. The slotted member is affixed to the annular disk and defines an interior void that opens to the hole. The tube and the slotted member define an annular passage therebetween. Elongated slots pass through the outer surface of the slotted member, each directed along a different non-diametrical chord of the slotted member. The elongated slots direct a gaseous stream into the interior void so as to impart both an inwardly-directed radial velocity component and a tangential velocity component to the gaseous stream.

  • Patent number: 8882491
    Abstract: The invention is a connection duct between the blower and a mixing device of a burner. The connection duct expands wedge-shaped along a first direction and diverts air from the blower to a second direction. The connection duct further comprises diverting means for diverting the air in a circular flow around the second direction corresponding to a longitudinal axis of the mixing device. The diverting means comprise a tube section with at least one inflow opening arranged in the peripheral wall of the diverting means. A truncated cone comprising a tapering section is arranged in the tube section so that the tapering section faces in the direction of the mixing device. A passage cross-section of the inflow opening can be adjusted by a tube arranged in the peripheral wall which can be rotated around the tube's longitudinal axis and bears against the internal surface of the tube section.

  • Patent number: 7669787
    Abstract: The present invention teaches a car wash wand having a fan mounted thereon which allows the wash wand user to blow the vehicle dry using the same lightweight hand carried device used to wash the car. The fan may be powered by the pressurized water flowing through the wash wand, which may be diverted to a turbine chamber to power the turbine, which in turn provides mechanical power to turn the fan. The wash wand may also have selection devices allowing at least two modes of operation: water coming out versus air coming out, and optionally a third mode of operation in which nothing comes out.

  • Patent number: 7059544
    Abstract: A vortex generator creates a waveform within a housing. The waveform evolves into a vortex as it exits an orifice of the housing. The vortex carries a bolus of active substances held within the housing. A different number of actives can be used. To form a waveform, the housing has a diaphragm with an actuator for moving the diaphragm. The housing may have a mechanism for facilitating directional pointing and/or causing oscillating movement of the housing to enable multi-directional targeting of the vortex.

  • Patent number: 6402505
    Abstract: In a combustion unit, a fuel collision member is disposed between a fuel injection valve and a combustion chamber. The fuel collision member is positioned so that, a part of fuel injected from said fuel injection valve is introduced into the combustion chamber while colliding with the fuel collision member, and the other part of fuel is directly introduced into the combustion chamber without colliding with the fuel collision member. Thus, fuel introduced into the combustion chamber is atomized while being introduced into the combustion chamber in a wide range.

  • Patent number: 6386863
    Abstract: A compound spin vane (CSV) for use in an air passage of a fossil fuel-fired burner. In one embodiment, the CSV is a multi-piece construction of platelike outer and inner vane elements connected to an intermediate platelike rail element. In another embodiment, the CSV includes at least two and possibly three vane portions, rigidly interconnected in spaced lateral relationship with respect to each other. If desired, the vane portions may be simple, curved planar surfaces, and may be arranged with trailing edges arranged at angles with respect to each other. The invention may be employed as a replacement for flat spin vanes found in secondary air passages of known single and dual register burners. When used in such manner in a single register burner, the invention changes secondary air flow characteristics so as to mimic those commonly found in a dual register burner.

  • Patent number: 6199367
    Abstract: A gas turbine engine carburetor includes a fuel injector and a cooperating air swirler for injecting fuel and air into a combustor. The fuel injector includes a hollow body joined to a supporting stem for receiving fuel therein for flow through an injector tip slidingly mounted to the injector body for movement relative thereto. The air swirler surrounds the injector tip and is spaced form the injector body to define an air inlet, and is spaced from the injector tip to define an air outlet. A spring operatively engages the injector body and the injector tip and is preloaded for biasing the injector tip to an initial position. The spring is sized so that increasing pressure of the fuel in the injector body further loads the spring for moving the injector tip from the initial position to a displaced position, with movement of the injector tip modulating airflow through the swirler for in-turn modulating the ratio of discharged fuel and air.
