Fuel Disperser Installed In Furnace Patents (Class 431/159)
  • Patent number: 9285113
    Abstract: A burner has a fuel/oxidant nozzles and a pair of dynamical lances spaced on either side thereof that inject a jet of fuel and primary oxidant along a fuel injection axis, and jets of secondary oxidant, respectively. Jets of actuating fluid impinge against the jets of secondary oxidant to fluidically angle the jets of secondary oxidant away from the fuel injection axis. The action of the angling away together with staging of the oxidant between primary and secondary oxidant injections allows achievement of distributed combustion conditions.

    Abstract: A combustor applied in thermophotovoltaic system comprises a combustion device and a reversed tube covering the combustion device. The combustion device includes a combustion body made of a transparent, and temperature resistant material and a burning unit disposed in the combustion body. When a burning-supported medium is adopted during burning via the burning unit, the radiant intensity is increased. The reversed tube thence further redirects the hot product gas for reheating an outer wail of the combustion body in combustion. Therefore, uniform illumination is accordingly resulted for enhancing the radiant intensity. Accordingly, a photovoltaic cell plate connected to the combustor preferably transforms light into electricity. The present invention fully utilizes a micro system as well as miniature energy to offer advanced electricity.

  • Patent number: 8057220
    Abstract: Disclosed is an air-assisted simplex spray nozzle assembly for a fuel burner that includes, inter alia, a nozzle body that has opposed upstream and downstream ends, wherein the downstream end of the nozzle body defines a fuel outlet, an adapter member that is engaged with the upstream end of the nozzle body and defines concentrically positioned air and fuel inlets for the nozzle assembly and an air cap that is positioned over the downstream end of the nozzle body. The nozzle assembly further includes a fuel circuit and a first air circuit. The fuel circuit directs fuel from a fuel pump toward the fuel outlet of the nozzle body. The fuel circuit extends from the fuel inlet of the adapter member through the nozzle body to the fuel outlet. The first air circuit directs assist air towards the fuel exiting from the fuel outlet.

  • Publication number: 20110244405
    Abstract: A low NOx burner includes an upper plate and a lower plate joined together. A chamber is defined between an upper inner portion and a lower inner portion. The peaks of upper and lower scalloped ridges are in contact such that multiple ports are defined. The ports extend radially outward from the chamber. The chamber is adapted to receive a fuel/air mixture through a fuel/air intake opening. The ports permit a flow of the fuel/air mixture from the chamber for combustion to create a diffuse flame. An intermediate portion is positioned such that the flame attaches to the intermediate portion. The intermediate portion and a trough are arranged such that flame is directed downwards to the trough from the intermediate portion and attaches to the trough. An outer rim is positioned and angled to attach the flame to the trough and to direct the flame upwards from the trough.

  • Patent number: 7963764
    Abstract: A lance for a hybrid burner of a combustor of a gas turbine, includes an inner passage for a liquid fuel, an outer passage coaxially enclosing the inner passage for a gaseous fuel, a plurality of star like arranged outer nozzles branching off radially from the outer passage, a plurality of inner nozzles, which branch off radially from the inner passage and which each extend coaxially inside one of the outer nozzles, and a distributor section, which is arranged upstream of the outer nozzles in the outer passage and has a plurality of star like arranged, coaxially extending through-openings for the gaseous fuel. In order to reduce the flow resistance in the gas path of the lance, the through-openings each have an opening width which is larger in the circumferential direction than in the radial direction.
