  • Patent number: 8196388
    Abstract: The present invention relates to a heating device for exhaust gas in an internal-combustion engine, which is driven by using LPG, LNG, a volatile oil, a light oil, biodiesel or oxygenated hydrocarbon being DME, the device consisting of a catalyst reactor reformer, an exhaust gas suction section and the second fuel supply device. The exhaust gas suction section is mounted for using oxygen included in the exhaust gas. When the heating device is driven, air and fuels are supplied to the catalyst reactor and the second fuel supply device via a single tube when the heating device is heated. The present invention provides with a heating device for exhaust gas capable of securing the durability of a heating device for exhaust gas and minimizing the amount of air supplied from the outside to the combustion reforming device by excluding carbon depositions in a tube due to a prolysis of LPG, LNG, a volatile oil, a light oil, biodiesel or oxygenated hydrocarbon being DME, and a method for driving the device.

  • Patent number: 6350116
    Abstract: The invention concerns a pre-vaporizing and pre-mixing burner for liquid fuels which has a fuel feed line (56), a pump which pressurizes the fuel in the feed line, a mixing region (123) and a fuel valve (119) which opens out into the mixing region and by means of which the fuel is atomized and fed to the air for combustion (127). According to the invention, the fuel is vaporized in an optimum manner in that the fuel valve opens automatically as from a given fuel pressure, and a heating device (128) is associated with the fuel valve.

  • Patent number: 5191930
    Abstract: A gas regenerator is provided having for the clean air a set of two adjacent parallel flow paths having hot and cold ends, and for the waste gas a set of two adjacent parallel different flow paths, having hot and cold ends, the air and waste gas being separated while passing through the mass storage and heat transfer material of the regenerator, valves arranged only at the cold ends of the flow paths are adapted to be selectively positioned for allowing the flow paths of each set to be alternately selected, and in which the different sets of flow paths are arranged perpendicularly or at another overlapping desired angle to each other.

  • Patent number: 4661057
    Abstract: A fuel gas combustor which utilizes thermal assisted expansion and mixing of the fuel gas and a combustion supporting gas for more complete combustion and greater heat output. A heat transfer device provides thermal feedback from the flame to the gas expansion zone. The invention is especially useful in hand-held torch tips. In a specific embodiment, the heat transfer device include a heat conducting element, at least the intermediate portion of which is rod shaped and sheathed in a non-conducting envelope.

  • Patent number: 4611985
    Abstract: A vaporization burner of the type that has a carrier connected with a fuel line on which an absorbent body is located is provided with a heat conducting body for quicker fuel vaporization and for increasing the temperature on the surface of the carrier that faces the combustion chamber. The heat conducting body is formed of a heat resistant and highly heat conductive material and projects into the flame zone of the combustion chamber. The heat conducting body may be attached releasably to the carrier or it may be fastened to it by means of press welding. The heat conducting body may be developed as a hollow body, preferably as a piece of pipe, whereby the end projecting into the flame zone may be open or closed. For closing of the end of the heat conducting body that projects into the flame zone, when the conductive body is formed from a piece of pipe, the free end may be compressed. Furthermore, the heat conducting body may be arranged centrally or eccentrically on the carrier.

  • Patent number: 4443180
    Abstract: A pressure atomizing liquid fuel burner having an improved turndown ratio is disclosed along with a method of increasing the turndown ratio in such burners. The burner includes means for adding an amount of gas to the liquid fuel prior to the injection of the fuel which causes the liquid fuel to foam such that a liquid-gas foamed mixture is injected. The relative amounts of the aeration gas and the liquid fuel are controlled such that the injection velocity is maintained relatively constant over a wide turndown ratio in the liquid fuel. The aeration gas to be added to the liquid fuel may be preheated prior to the addition of the gas to the liquid fuel.
