  • air, nitrogen, argon, hydrogen, helium or the like is jetted as working gas from a plasma generating device to obtain a high temperature.
  • An object of the present invention is to provide a burner that may elevate a temperature of combustion flame with ease without adding the oxygen or preheating the air.
  • a burner according to the present invention is characterized in that a plurality of magnets having the same polarity are arranged to be present around a periphery of a combustion chamber around an outer circumference of a combustion sleeve that forms the combustion chamber.
  • the magnetic action such as a magnetic mirror or a drift effect is added to the flame within the combustion sleeve so that the flame is converged. It is possible to obtain a combustion flame having a higher temperature than that of the normal combustion burner or plasma burner.
  • each magnet may be protected from the high temperature.
  • the burner according to this embodiment is a plasma burner with a mixture sleeve 2 forming a mixture chamber 1.
  • the mixture sleeve 2 is composed of a sleeve portion 2b having a flanged portion 2a at a proximal end, an enlarge diameter stepped portion 2c formed integrally with the distal end of the sleeve portion 2b, a tapered sleeve portion 2d having a smaller diameter from an inlet port toward an outlet port and formed integrally with an outer circumference of the enlarged diameter stepped portion 2c, and a flanged portion 2e provided at an outer circumference of a tip end of the tapered sleeve portion 2d.

  • a plasma generating means 6 for making the air flow, flowing through the interior of the inner sleeve 4, under the plasma condition, thereby generating a plasma flow.
  • an annular insulating support member 7 is mounted along an inner circumference of the inner sleeve 4, and a plurality of rod-shaped electrodes 8 are penetrated into and supported to the insulating support member 7.
  • These electrodes 8 are used as anodes and the inner sleeve 4 is used as a cathode.
  • a high voltage is applied in between these electrodes to thereby make the air flow, flowing within the inner sleeve 4, under the plasma condition.
  • spiral vanes 9 are arranged in a spiral manner between the outer sleeve 3 and the inner sleeve 4, and the air flow flowing between the outer sleeve 3 and the inner sleeve 4 is made into a swirl flow to surround and converge the plasma flow.
  • the inner sleeve 4 is supported to the outer sleeve 3 by the spiral vane 9.
  • a plurality of fuel injection nozzles 10 for injecting the fuel around the plasma flow within the mixture chamber 1 and mixing the fuel with the swirl flow are provided through and to the enlarged diameter stepped portion 2c of the mixture sleeve 2.
  • a joint flow portion 13 with the fuel passage 12 is kept under a negative pressure by its dynamic pressure, and the fuel is sucked and atomized so that the mixture flow of the fuel and the air from the throat 14 is injected to the outside of the nozzle sleeve 15.
  • the combustion sleeve 16 is connected through the flanged portion 16a to the flanged portion 2e of the mixture sleeve 2 on the outlet side of the mixture chamber 1.
