Definitions

  • the present invention relates to a burner of the external mixture type.
  • the treatment of certain industrial waste by incineration with oxygen is currently considered to be a very promising avenue.
  • the waste in the form of a gas, a liquid, or a foam, possibly containing suitable additives, is sent to a burner supplied with two pure oxygen, or at least of high content.
  • a process which has been developed for treating certain aqueous effluents originating from the leaching of steam generators from nuclear power plants, but which can have many other applications.
  • This process consists in dispersing the waste to be incinerated in an aqueous solution containing a surfactant as well as, if necessary, a fuel, in converting this solution into a slightly pressurized foam, and in transferring this foam into a cyclone oven by passing it in an oxygen burner.
  • the object of the present invention is to provide a burner having improved performance compared to the device of the prior art, a homogeneous flame which can occur at a short distance, substantially constant despite variations in the fuel, from the burner nose.
  • the burner of the invention can be used in all fields, without being limited to the incineration of waste.
  • the invention provides a burner of the external mixture type, comprising a nose pierced with a passage for supplying a first fluid, and a passage for supplying a second fluid capable of form a flame when it is in contact with the first, the burner operating by formation of the flame at a short distance from the nose, this burner having the particularity that the nose consists of a part having an outer face pierced with holes, some of these holes opening into a chamber supplied with the first fluid, this chamber being delimited by the nose, a side wall pierced with orifices for the arrival of the first fluid, and a bottom, transverse to the side wall, the side wall being in tight connection with the nose and with the bottom, and certain other holes of the nose each containing a tube fixed to the nose in a leaktight manner, and crossing the bottom also in a leaktight manner, to lead into a core duct born of the second fluid, all of the holes opening into the chamber and all of the holes containing tubes, each having a regular and
  • the first fluid can be fuel, in the form of foam or gas or liquid, and the second fluid can be oxygen.
  • the number and the respective diameters of the holes opening into the chamber and of the tubes is obviously a function of the desired combustion, and in particular of the nature of the fuel and of the fuel.
  • the body C comprises several concentric tubes, namely, starting from the axis, a first tube 2 which is connected to an oxygen inlet inlet 3, and which, on the opposite side, leads to the head T.
  • a second tube 4 defines with tube 2 an annular conduit 5 which serves to bring the fuel from a fuel inlet 6 to the head T.
  • a third and a fourth concentric tubes 7, 8 define between them two annular spaces intended for the circulation of a cooling fluid, which enters the outer annular space 9 through an inlet 10, and leaves the inner annular space 11 through an outlet 12.
  • the two annular spaces 9 and 11 communicate with each other at the level of the burner head T.
  • the burner head comprises a part called "nose", which has the general shape of a disc 13, pierced, in its central part, with a multitude of orifices 14, 15.
  • the outer face 16 of the nose 13 is flat , while its opposite face 17 carries a first external projection 18 intended for its connection with the external tube 8, and another annular projection 19 which serves to delimit, with the face 17, a chamber 20.
  • a sealing piece 21 has the general shape of a cylinder open at one end and closed at the other end by a perforated disc 22.
  • the cylindrical part 23 of the piece 21 is welded at its ends to the cylindrical relief 19 of the nose.
  • a number of radial orifices 24, arranged in two radial planes, are provided in the cylindrical part 23, a short distance from the disc 22.
  • FIG. 3 shows their regular distribution. A number of these holes 14 are in axial alignment with holes 25 of the closure piece 21, and a tube 26 is crimped in each hole 14 and each corresponding hole 25. All the holes 25 of the disc 22 are connected to a corresponding bore 14 of the nose, so that there is no communication between the chamber 20 and the space 27 which is on the opposite face of the disc 22, and which extends the oxygen supply duct .
  • FIG 3 there is shown in dark tubes 14 which are provided with tubes 26, and therefore communicate with the holes 25 and with the space 27, and in light the tubes 15 which communicate with the chamber 20. It can be seen that the holes 14 and the holes 15 are evenly distributed. The ratio of the number of holes 14 to the number of holes 15 is obviously adapted according to the problem posed.
  • Chamber 20 also constitutes a buffer chamber which homogenizes variations in the composition of the fuel.
  • the conduits 26, and the holes 14 route the oxygen directly from the space 27, without putting it in contact with the fuel in the chamber 20. Again the distribution of the holes 14 ensures a regular distribution.
  • the structure of the burner thus makes it possible to obtain a particularly homogeneous and constant flame.
  • the double-walled cooling circuit 9, 11 extends practically to the level of the disc 13. It therefore arrives closer to the external face 16 of the nose than the weld connecting the shoulder 28 to the tube 4. This weld is therefore cooled effectively, which is a guarantee of duration.
