Flame Holder Having Protective Flame Enclosing Or Flame Stabilizing Structure Patents (Class 431/350)
  • Patent number: 10378441
    Abstract: A burner module in an air stream has a feed pipe of substantially circular cross section and an axis, fuel injection orifices situated on the pipe and intended to produce a flame, oxidant injection orifices and fins arranged symmetrically with respect to a plane P of flow of the fuel upstream of the burner module and laterally on the pipe on each side of the fuel injection orifices. There are at least two fuel injection orifices in a section of the pipe and they have an axis that makes an angle ? with the plane of flow P of the oxidant. In this way, gas is injected at several orifices situated in at least two divergent planes. These two planes delimit a space to which fuel and to which oxidant are not supplied.

  • Patent number: 10151487
    Abstract: The invention refers to a sequential combustor arrangement including a first combustor with a first burner for admitting a first fuel into a combustor inlet gas during operation and a first combustion chamber for burning the first fuel, a dilution gas admixer for admixing a dilution gas to the first combustor combustion products leaving the first combustion chamber, and a second burner for admixing a second fuel and a second combustion chamber. To assure good mixing over a wide operating range, the ratio of the pressure loss of the first combustor to the pressure loss of the dilution gas admixer is in the range of 1 to 6. The invention further refers to a gas turbine including such a sequential combustor arrangement as well as method for operating a gas turbine with such a sequential combustor arrangement.

    Abstract: A torch tip protector is elastically retained to an oxyacetylene cutting torch tip during transport. The torch tip protector in the preferred embodiment has a protector cap having a generally disc-shaped base and a truncated conical side wall that together form a cup or thimble-shaped torch tip cover. This torch tip cover operatively encompasses a torch tip and thereby operatively blocks access and fouling of the torch tip. To ensure that the protector cap stays engaged with torch tip, a hook secures to and is manually removable from at least one of the torch gas lines. A spring couples to the hook and couples with the protector cap to provide an elastic tension force that draws the protector cap towards hook and thereby secures the protector cap onto the torch tip.

The fuel tube is at a distance from the top of the housing so that substantially all of the fuel is entrained by the combustion air before the fuel reaches the top. The heat dissipating surface is disposed across the top of the housing and supports a flame. The heat dissipating surface includes enough open area so that the fuel/air mixture passes through the porous heat dissipating surface unimpeded. The heat dissipating surface dissipates heat from the flame and prevents flashback.

    Abstract: A hot air blower includes a shell including a fan mechanism, a combustion device, a vane mechanism, and a flame protector disposed therein. The vane mechanism includes a clipping seat and a plurality of guiding vanes extended thereon. The plurality of guiding vanes extend obliquely and prevents the air passing through the vane mechanism from generating turbulence. The clipping seat and the flame protector form a half-closed combustion chamber therebetween. Heat in the half-closed combustion chamber causes a thermal expansion of the air and, thereby increasing a speed and a volume of the air passing the guiding vanes of the vane mechanism. The heated air is discharged from an external flow tube and which controls a heating range of an area of the hot air blower.

  • Publication number: 20130196270
    Abstract: A jet micro-induced flow reversals combustor is used to reduce NOx emissions. The combustor has a nozzle disposed at the head end of the combustion chamber. The nozzle includes a plurality of jets for injecting a fuel and oxidant mixture stream into the combustion chamber. A combustion liner is disposed within the casing on one side of the nozzle and a plenum chamber is disposed on another side of the nozzle and configured to provide an input of a fuel and oxidant. The nozzle and the combustion liner are sized and shaped to input the fuel and oxidant mixture stream into the combustion liner at a high velocity ratio wherein a jet velocity is greater than a combustion mean velocity within the combustion liner, to increase turbulence within the combustion liner and reduce combustion emissions.
