    Abstract: A catalytic tank heater includes a catalytic heating element supported on an LPG tank by a support structure that holds the element in a position facing the tank. Vapor from the tank is provided as fuel to the heating element, and is regulated to increase heat output as tank pressure drops. The heating element is internally separated into a pilot heater and a main heater, with respective separate fuel inlets. The pilot heater remains in continual operation, but the main heater is operated only while tank pressure is below a threshold. Operation of the pilot heater keeps a portion of the catalyst hot, so that, when tank pressure drops below the threshold, and fuel is supplied to the main heater, catalytic combustion quickly expands from the area surrounding the pilot heater to the remainder of the catalyst.

  • 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.

  • Publication number: 20140272730
    Abstract: A combustion system can allow for the interaction of a magnetic field and an electrical current within a flame supported by a nozzle. The magnetic field can be generated by one or more electromagnets in proximity to or contact with the flame. The electrical current can be generated by a voltage potential difference generated between a first electrode and a second electrode located at tip and base regions of the flame, respectively. The interaction between the electrical current and the magnetic field can generate a force that can produce a constant lateral movement of ions within flame, generating a vortex that can enhance mixing of air and fuel. The speed and direction of this vortex can be controlled by actively varying the magnitude and direction of electrical currents applied in the one or more electromagnets and the electric current induced within the flame, as well as by varying the spatial relationship between these two factors.

    Abstract: A gas burner safety system comprises dual sensor arrays, the first array positioned proximal to the gas burner and the second array positioned proximal to a control used to turn on and of and regulate the flame of the gas burner. The first array senses the flame components such that a flame signature is obtained when no object is placed on or above the flame and a flame image is obtained when an object is proximal to the flame. By comparing the flame signature and the flame image, a central control unit operatively connected to the sensor arrays can determine the presence or absence of an object proximal to the flame. The second sensor array is positioned to detect a human hand proximal to the control. In operation, if the flame image matches the flame signature and a human hand is not detected proximal to the control, the central control unit turns off the gas burner by causing the closure of a valve in the gas supply line to the gas burner.

  • Publication number: 20140147796
    Abstract: An air fire lighter having fuel, an igniter and a ducted fan for igniting a solid fuel fire. The fuel travels through the fire lighter to a collar at a distal end of the fire lighter, transforming into a vapor that is ignited by an igniter. As the solid fuel begins to glow at the initiation of the fire, the fan is activated, shutting off the vapors from the fuel. The fan blows air through a chamber onto the fire, causing the fire to spread throughout the solid fuel, establishing and spreading the fire through an ignition period. The chamber has a volume and ducting for providing optimal airflow to the fire. The fan is battery-operated. The lighter is lightweight and compact with a swiveling handle that adjusts for optimal placement of the lighter for addressing the solid fuel, folding for portability and storage.

  • Publication number: 20140134545
    Abstract: A device for dispensing and automatically extinguishing pre-waxed hemp wick is described. The invention includes a main body, consisting of an area that may readily be gripped by a user and another area to store a length of pre-waxed wick. The user pulls or unwinds a length of wick from the storage area, and pushes the wick at the point where it should be extinguished into a notch cut into a sufficiently flame-retardant material located at the top of the main body. The notch is in width slightly smaller than standard pre-waxed hemp wick, therefore securely holding the wick and causing the burning wick to automatically extinguish by removing air from the combustion process when the flame reaches the notch. A recess located directly under the notch allows for easy retrieval of the next portion of wick to be burned.
