  • Patent number: 9423133
    Abstract: An apparatus and method for assisting with the combustion of fuel are described. The apparatus includes a swirler assembly and a fuel nozzle. Fuel is directed into a fuel nozzle mixing chamber and combines with air therein to form a fuel-air mixture. At least one plasma generator, at least partially within the fuel nozzle, generates an at least one of an at least partially ionized air-fuel mixture and an at least partially dissociated air-fuel mixture (“at least partially I/D air-fuel mixture”) via a plasma generator discharge. A combustion chamber inlet admits the at least partially I/D air-fuel mixture from the plasma generator into a combustion chamber internal volume. Combustion air flows through the swirler body and into the combustion chamber internal volume. Combustion of the at least partially I/D air-fuel mixture with the combustion air occurs at least partially within the combustion chamber internal volume to responsively produce products.

  • Publication number: 20140377710
    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.

  • Patent number: 6102687
    Abstract: The invention relates to clean burning of fuel oil with air. More specifically, to a fuel burning combustion head using a low-pressure, high air flow atomizing nozzle so that there will be a complete combustion oil resulting in a minimum emission of pollutants. The inventors have devised a fuel burner that uses a low pressure air atomizing nozzle. The improved fuel burner does not result in the use of additional compressors or the introduction of pressurized gases downstream, nor does it require a complex design.

  • Patent number: 6048196
    Abstract: A self-grounding igniter for an industrial burner that is more durable and less fragile, by virtue of the insulating jacket being relatively short and limited to the tip end of the igniter. The burner has a final inlet, an air inlet, a housing and a burner nozzle inside the housing. The igniter comprises a metal rod having a discharge electrode at one end and a mount and connector at the other end. The connector is adapted to be electrically coupled to a power source. An insulating jacket circumscribes a top end segment of the metal rod in proximity to the discharge electrode. A ground electrode metal sleeve is mounted to the outside of the insulating jacket in fixed proximity to the discharge electrode, thereby forming a spark gap having a fixed distance. This configuration provides an exposed metal surface on the rod between the insulating jacket and the mount. The exposed metal surface has a length substantially corresponding to the distance between the housing and the burner nozzle.

  • Patent number: 6048197
    Abstract: A retention head for the end of the burner nozzle housing on a waste oil furnace controlS the flow of combustion air relative to the flame produced by the burner nozzle. The retention head is formed as a cup-shaped member that mounts in a detachable manner on the outside of the burner nozzle housing. The retention head has an operative face having a central opening through which a portion of the combustion air can flow and support the flame passing through the opening. A solid ring defining the central opening forces air into circumferential vented slots around the perimeter of the retention head. The vented slots have angled flaps that direct the combustion air into a spiraled flow pattern circumferentially around the flame. The retention head has an inwardly curved periphery to help direct combustion air into an inward pattern surrounding the flame.

  • Patent number: 5702055
    Abstract: In a vehicle heating appliance, a burner is supplied with combustion air by a combustion air fan and with fuel by a fuel dosing pump. The heat generated by the burner in a combustion chamber is absorbed by a liquid or gaseous heat transfer medium through a heat exchanger that surrounds the combustion chamber and is transferred to the areas to be heated. In order to avoid malfunctions of the fuel dosing pump caused by steam bubbles produced by overheating, the fuel dosing pump must be kept cool. To ensure an efficient cooling of the fuel dosing pump, the fuel dosing pump is mounted in a compact manner in a suction channel (8) of the combustion air fan (1). When the vehicle heating appliance is in operation, combustion air flows past the outer surface of the fuel dosing pump (14) and cools the pump before being led to the inlet side of the combustion air fan (1, 4).

  • Patent number: 5413478
    Abstract: A burner with an electric ignition device, for use in an internal combustion engine, a combustion chamber of a gas turbine set, or for a furnace installation, includes two hollow part-conical bodies that are positioned to form a conical combustion space and are offset so that longitudinally extending, tangential inlet slots are formed to conduct combustion air into the combustion space. Inflow orifices provided at the tangential inlet slots feed fuel to the inflowing combustion air to be mixed and carded into the combustion space. An electric ignition device is positioned so that spark producing ends are positioned at a central vertex region of the combustion space. The position of the ignition device protects the device from excessive thermal loading, and allows the burner to be operated at a higher, more efficient temperature.

  • Patent number: 5360334
    Abstract: The present invention relates generally to devices designed for the combustion of liquid fuels and specifically to an improved apparatus for burning high-viscosity and waste oil. The subject invention utilizes a piston mechanism to transport fuel from its source to the subject burner. The piston mechanism, in conjunction with a pressure-sensitive valve device, also pressurizes the fuel to a predetermined level before releasing said fuel through a nozzle for pressurized dispersion atomization. The piston speed and stroke length can be adjusted in order to regulate fuel flow. After emission from the nozzle, the atomized fuel encounters a single-spark ignition device to induce flame. The atomized fuel and flame produced is enveloped by a unique retention head designed to promote complete fuel combustion and protect the burner chamber from over-heating.

  • Patent number: 5249955
    Abstract: In a burner for operating an internal combustion engine, a combustion chamber of a gas turbine or firing equipment, which consists essentially of at least two hollow conical partial bodies (1, 2) positioned one upon the other in the flow direction, the ignition of the air/fuel mixture forming in the hollow conical space (14) takes place by means of ignition electrodes (24a, 24b, 25a, 25b) which are placed at a location where there is a low flow velocity of the combustion air (15). This achieves the effect that the flame tongues starting from the electrode ends (25a, 25b) of the ignition electrodes (24a, 24b) can feed a flame front (7) forming at the outlet from the burner continuously and along ordered paths, i.e. paths directed in the flow direction with slight swirl in consequence of the motion of the combustion air (15), so that a stable reverse flow zone (6) forms.
