Definitions

  • the combustion chamber has a burner tube whose closed end has at least one fuel injector and whose open end emerges into a pipe leading the gaseous mixture towards its position of use.
  • the burner tube includes a number of orifices distributed circumferentially and along axially staggered sections.
  • An outer enclosure is arranged around the burner tube and connected in sealed manner to the open end of the said burner tube.
  • a first pipe, supplied with oxygen-rich gas, is connected in the neighborhood of the closed end of the burner tube.
  • a second pipe supplied with oxygen-poor gas is connected in the neighborhood of the open end of the burner tube.
  • the invention relates to combustion chambers supplied, on one hand, by fuel, and, on the other hand, both by gas rich in oxygen intended for ensuring the combustion and by a gas poor in oxygen intended to be mixed with the gases resulting from the combustion.
  • the invention relates more particularly, but not exclusively, among these combustion chambers, to those applied to the reheating of exhaust gases (gases poor in oxygen) from an internal combustion engine supercharged by a turbocompressor unit, of which the compressor supplies in parallel the said internal combustion engine and the combustion chamber (gas rich in oxygen).
  • the combustion chamber according to the invention includes a burner tube of which the closed end bears at least one fuel injector and of which burner tube the open end opens into a pipe leading the gaseous mixture towards its position of use, this burner tube including a certain number of orifices distributed circumferentially and along sections staggered axially, and it is characterized by the fact that an outer enclosure is arranged around the bumer tube and is connected in sealed manner to the open end of the said burner tube, said outer enclosure being supplied, on one hand, with gas rich in oxygen, by first means, in the neighborhood of said fuel injector, and, on the other hand, with gas poor in oxygen, be second means, more remote from said fuel injector.
  • the ratio between the flow rate of the oxygen-rich gas and the flow rate of the oxygen-poor gas can vary without the organization of the combustion in the burner tube being disturbed, since there is produced in fact in the space bounded by the outer enclosure and the burner tube a zone of separation between the oxygen-rich gas and the oxygen-poor gas, this zone of separation moving when the abovesaid ratio varies.
  • the invention consists, apart from the main feature which has just been considered, of certain other features which are preferably used at the same time and which will be more explicitly considered below.
  • FIG. 1 is a diagrammatic section of a combustion chamber constructed according to the invention
  • FIG. 2 is a diagrammatic section of a second embodiment of a combustion chamber constructed according to the invention.
  • FIG. 3 shows diagrammatically a supercharged Diesel engine equipped with a combustion chamber according to a first embodiment of the invention
  • FIG. 4 shows diagrammatically a supercharged'Diesel engine equipped with a combustion chamber according to a second embodiment of the invention.
  • the combustion chamber shown in FIGS. 1 and 2 includes a burner tube 1 whose closed end 2 bears a fuel injector 3, and whose open end 4 opens into a pipe leading the gaseous mixture towards its position of use.
  • the burner tube 1 includes a certain number of orifices 7 distributed circumferentially and along sections staggered axially.
  • An outer enclosure 8 is arranged around the burner tube 1 and is connected in a sealed manner to the open end 4 of the said burner tube 1.

  • a second pipe 10 (constituting the second means) supplies, with exhaust gases emerging from the Diesel engine 5, the portion of this enclosure 8 situated more remote from the fuel injector 3, i.e. in the neighborhood of the open end 4 of the burner tube 1.
  • the outer enclosure 8 can surround the burner tube 1 at the level of its closed end 2, it seems preferable to arrange this outer enclosure 8 so that it is connected in sealed manner on the burner tube 1 at the level of its closed end 2.
  • the first pipe 9 is connected to the outer enclosure 8 through a distributing tank 11. a
  • the second pipe 10 As for the second pipe 10, and according to the embodiment illustrated in FIG. 1, it is connected to the outer enclosure 8 through a distributing tank 12.
