  • Patent number: 8858222
    Abstract: A new approach for igniting an air-fuel mixture in a turbine or other engine is disclosed. Resonance-enhanced multiphoton ionization (REMPI) is used to generate volume ionization within an air-fuel flow and induce an ignition arc. The output of a relatively low energy single pulsed ultraviolet laser is aimed across an electric field inside a volume of air to create a pre-ionized channel so that a smaller voltage electric field is sufficient to create an electrical arc that follows the pre-ionized channel and will ignite an air-fuel mixture. Because the arc follows the pre-ionized channel, it can be directed to an optimal location inside an ignition volume for igniting the air-fuel mixture. A specific example embodiment is described using a 287.5 nm wavelength pulsed ultraviolet laser to excite ground state oxygen molecules to a specific excited state having a coincident term energy with a specific nitrogen molecule excited state.

  • Patent number: 8702421
    Abstract: A burner includes a housing 1, an intake pipe 3 and a burner head 4. Gas in the housing 1 is supplied to the burner head 4 through the intake pipe 3. An electric wire 8 extends through the intake pipe 3 which connects a piezoelectric element 7 to a core wire 10 from which electric discharge is generated near burner ports 9 of the burner head 4 by the piezoelectric element 7. Since the wire 8 is not exposed to outside the intake pipe 3, the wire 8 is never caught and damaged by an external object. Since air-gas mixture which is kept at around the room temperature is flowing through the intake pipe 3, the wire 8 is less likely to overheat during use of the burner. Thus, it is not necessary to provide the wire 8 with a shield plate for protecting the wire 8.

    Abstract: The detonation propagation in a channel geometry which suppresses detonation propagation in one direction, allows it in another direction, and does not create flow restrictions in the channel. The geometry consists of a series of divergent sections separated by wedges that form a sawtooth shape. The detonation fails to propagate through this geometry in one direction because the detonation front is weakened by diffraction, and reignition centers are isolated from the main channel. In an opposite direction, convergent parts of the geometry support the detonation propagation, because subsequent shock collisions with oblique walls that form convergent sections create powerful transverse waves. These powerful transverse waves help the detonation propagation or reignite it.

  • Publication number: 20120037053
    Abstract: The invention describes a burner for a thermal post-combustion device, which has a burner jet arranged in a housing. Arranged on the end region of the housing is a swirl apparatus, through which the exhaust gas to be purified can be made to flow. The burner jet comprises an outer tube and an inner tube, wherein it is possible for combustion gas to be made to flow through the interspace between said two tubes as far as an annular outlet gap in the end region thereof. The flow path for the combustion gas has a bottleneck in the vicinity of the outlet gap. In this way, a compact flame can be achieved, the form of which can be designated “bell-shaped” and which, for a given volume, has a relatively small surface. Although, such a flame has poor CO2 values, the swirl apparatus ensures that the exhaust gas burns in the flame with very low NOx and CO values.

  • Publication number: 20110003261
    Abstract: A torch assembly comprises a rigid elongated burner tube having a distal end with a bend terminating in a fuel discharge nozzle tip directed backwardly toward the elongated burner tube in a J-shape configuration forming an acute angle relative to the longitudinal axis of the elongated burner tube. The nozzle tip is configured to be positioned in hard to reach places for treatment of a part by the ignited fuel. The elongated burner tube rotates 360 degrees about its longitudinal axis. An ignition device may be mounted on the elongated burner tube for igniting the fuel. Alternately, the elongated burner tube may be comprised of a flexible stay put metallic tubing which can be formed into various configurations and which remains in this configuration until it is formed into a different configuration.

  • Patent number: 7791002
    Abstract: A battery powered cigarette lighter having a switch which is activated by a change in air pressure or air flow is described. The change in air pressure or air flow, which is caused by the consumer forcing air through the air permeable cigarette, causes the switch to close thereby allowing the lighter's direct current power supply to increase the temperature of the lighter's heating element above the cigarette's ignition point.

  • Patent number: 7735315
    Abstract: The invention relates to a device and a method for producing an operating medium for a motor vehicle, especially for use in the exhaust gas post-treatment of the motor vehicle. According to said method, an operating medium is produced from an initial product and air using a catalyst device. Said initial product is heated and mixed with air and the heated mixture of initial product/air is fed to the catalyst device. A part of the initial product is converted to the gaseous phase by means of a preheating element and is entrained by a stream of air when leaving the preheating element, said stream of air leading to a combustion chamber. The method allows to efficiently produce an operating medium, especially a reducing agent for regenerating NOx storage catalysts.
