Definitions

  • the invention relates to a device intended to bring together a gaseous fuel and an oxidant in proportions allowing optimal burning, so as to obtain, in particular for a combustible gas supplied under low pressure and containing hydrocarbons, smokeless combustion
  • Figure 1 schematically shows a device according to the invention in front view and in section along I-I.
  • FIG. 2a schematically shows the device of Figure 1 in top view with a plurality of tubes arranged annularly on a single ring whose center is located on the axis of the venturi body.
  • Figure 2b shows schematically, in top view, a variant of the device of Figure 1 with a plurality of tubes distributed over two rings.
  • FIG. 2c schematically represents, in top view, another variant of the device of FIG. 1 in which the central tube for supplying combustible gas has been replaced by a second plurality of tubes, arranged in an annular manner, according to a crown.
  • the device according to the invention comprises a central supply of combustible gas 1 disposed at the center and at the inlet of a body 2 forming a venturi.
  • the body 2 comprises a lower frustoconical part 3 generally called “converging” and which is extended by a cylindrical part 4 called “neck”. This cylindrical part 3 is extended by an upper frustoconical part 5 called "divergent”.
  • the central gas supply 1 generally comprises a central tube of annular cross section and substantially coaxial with the body 2. This central tube extends from the outside, passing through the convergent 3, to a point located in the body 2, in general at the junction of the convergent 3 and the neck 4.
  • the device according to the invention comprises three annularly disposed tubes, the maximum number of tubes depending on the size of body forming venturi 2 and up to several tens.
  • the arrangement of the tubes 6 is generally regular and annular, as best appears in Figures 2a and 2b.
  • these additional tubes 6 are substantially identical, of substantially circular cross section, and at least the tubes arranged annularly around the central supply 1 and located furthest outside the axis AA of the body forming a venturi. , are capable of injecting the combustible gas into said body at an angle ⁇ , formed with the axis AA of the venturi body, greater than 3 °, and preferably substantially equal to that formed by the divergent with said axis
  • Their lower part 8 may be cylindrical and substantially parallel to the axis AA of the body 2, while. as can be seen in FIG.
  • the angle of inclination ⁇ of the upper part 7 relative to the axis AA is substantially equal to the angle of inclination of the divergent 5 relative to this same axis AA
  • the axes of the tubes may form with the axis of the venturi body, an angle equal to that formed by the divergent with the axis of said body
  • the tubes can be arranged, as shown in FIG. 2b, in an annular fashion around the central fuel gas supply tube, along several rings, the centers of which are located on the axis AA of the venturi body 2
  • the additional tubes 6 all generally penetrate into the body 2 of the same depth, which can be identical to or less than the penetration depth of the central tube 1 into the body 2
  • This central tube can have a different diameter, preferably greater than the diameter tubes arranged in an annular manner.
  • the central tube 1 is replaced by a second plurality of tubes arranged in an annular manner around the axis AA so that they are surrounded by the tubes 6, this second plurality of tubes being arranged annularly along at least one ring, the center of which is located on the axis AA of the venturi body
  • Each tube 6 is dimensioned so that on the one hand, its internal diameter is identical to that of all the tubes arranged annularly on at least one crown, and on the other hand, so that it can transport between 1% and 33% and preferably between 5 and 33% of the combustible gas
  • all the ends of the tubes arranged on at least one ring can be equipped with gas injection devices, such as injection nozzles
  • the central tube 1, or, where appropriate, the second plurality of tubes arranged at least on a crown which replaces it, as well as the additional tubes 6 also arranged on at least one crown, can all be connected to the same supply tube. 9 in combustible gas. In this case, they are connected via the supply tube 9 to a source of combustible gas which may be composed, for example, of hydrocarbons, hydrogen sulfide HS or a mixture of these gases La combustion occurs at the outlet of tubes 1 and 6, inside the body
  • the Applicant has carried out tests on a burner on the ground called "burn pit".
  • a conventional burner composed of a single tube for supplying the gas to be burned and a venturi comprising only a central tube for supplying
  • smoke-free combustion is obtained.
  • the condensates entrained in the flame also burn without smoke. Obtaining complete combustion with the conventional burner would have required a gas pressure 30 times higher.
  • the use of the device according to the invention implements operating conditions conducive to the reduction of nitrogen oxides, such as the staging of the combustion air, the elimination of very hot zones of the flame by homogenization of the temperatures thereof, which is of certain interest, since it has been established that the nitrogen oxides formed during combustion contribute to the process of acidification, photochemical pollution, reduction of the ozone layer and increased greenhouse effect.
