Definitions

  • the present invention relates to a venturi burner, and more particularly to a venturi burner that can efficiently combust fuel gas.
  • the venting flare system can process the excess, harmful and unbalanced exhaust gas discharged from the production device in time, and can handle the test vehicle, the unqualified gas generated during the parking, and the large amount of gas instantaneously released during the accident to ensure the device.
  • Torch combustion should maintain the stability of the flame.
  • the normal and stable flame flame should be at the top of the torch standpipe.
  • the speed at which the torch gas leaves the torch head is compatible with the burning speed. However, if the velocity of the gas is too large, the flame at the top of the torch riser rises above the burner and mixes with the air turbulent flow, which will result in "off-fire", that is, the flame will leave the top of the torch head a certain distance and severe vibration will occur.

Abstract

L'invention concerne un brûleur à Venturi très efficace, comprenant un tube de Venturi (2), une buse (3) et un stabilisateur de flamme (4). Le tube de Venturi (2) comporte une extrémité (5) d'entrée d'air et une extrémité (6) de sortie d'air ; la buse (3) est disposée au niveau de l'extrémité (5) d'entrée d'air et le stabilisateur de flamme (4) est disposé au niveau de l'extrémité (6) de sortie d'air. Le stabilisateur de flamme (4) comprend un manchon (7) relié à l'extrémité (6) de sortie d'air du tube de Venturi (2), et une bague (8) de stabilisation de flamme. La bague (8) de stabilisation de flamme est munie d'un trou central (9) et d'un anneau de trous traversants (10) répartis uniformément autour du trou central (9). La face de paroi du trou central (9) est munie d'une pluralité de rainures (11) s'étendant le long de la direction axiale de la bague (8) de stabilisation de flamme.
