Abstract
Abstract 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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
197 words
A power plant comprising an internal combustion engine provided with an intake manifold and an exhaust manifold, said internal combustion engine being turbo-charged by at least one compressor driven by at least one turbine and a combustion chamber comprising: a burner tube having a closed end provided with at least one fuel injector and an open end communicating with said turbine, said burner tube including a plurality of orifices circumferentially and axially spaced, an outer enclosure arranged around said burner tube and connected in a sealed manner around the open end of said burner tube, first connecting means introducing oxygen-rich gas from said compressor to a first zone of said outer enclosure in the neighborhood of said fuel injector, and second connecting means introducing exhaust gases from said exhaust manifold to a second zone of said outer enclosure more remote from said fuel injector, said outer enclosure defining, around said burner tube, an unobstructed annular space between said first zone and said second zone, whereby a front between said oxygen-rich gas and said exhaust gas in said outer enclosure is mobile according to their relative flow rates without disturbing the stability of combustion in the burner tube.
Claim 2
Dependent Claim
197 words
A power plant comprising an internal combustion engine provided with an intake manifold and an exhaust manifold, said internal combustion engine being turbo-charged by at least one compressor driven by at least one turbine and a combustion chamber comprising: a burner tube having a closed end provided with at least one fuel injector and an open end communicating with said turbine, said burner tube including a plurality of orifices circumferentially and axially spaced, an outer enclosure arranged around said burner tube and connected in a sealed manner around the open end of said burner tube, first connecting means introducing oxygen-rich gas from said compressor to a first zone of said outer enclosure in the neighborhood of said fuel injector, and second connecting means introducing exhaust gases from said exhaust manifold to a second zone of said outer enclosure more remote from said fuel injector, said outer enclosure defining, around said burner tube, an unobstructed annular space between said first zone and said second zone, whereby a front between said oxygen-rich gas and said exhaust gas in said outer enclosure is mobile according to their relative flow rates without disturbing the stability of combustion in the burner tube.
Claim 3
Dependent Claim
29 words
Combustion chamber according to claim 1, wherein the outer enclosure is connected in sealed manner onto the periphery of the burner tube at the level of its closed end.
Claim 4
Dependent Claim
35 words
The power plant chamber according to claim 1, wherein the first connecting means comprises a first pipe and a first distributing tank, said first pipe being connected to the outer enclosure through said distributing tank.
Claim 5
Dependent Claim
34 words
The power plant according to claim 1, wherein said second connecting means comprises a second pipe and a second distributing tank, said second pipe being connected to the outer enclosure through said distributing tank.
Claim 6
Dependent Claim
90 words
The power plant according to claim 1, wherein said second connecting means comprises a second pipe, an annular enclosure and a second distributing tank, said second pipe being connected to said annular enclosure through said distributing tank, said annular enclosure surrounding the outer enclosure at the level of its part neighboring the open end of the burner tube, orifices distributed circumferentially and along sections staggered axially being arranged in the walls of the outer enclosure to ensure the passage of the gases from the annular enclosure to the outer enclosure.
Claim 7
Dependent Claim
47 words
The power plant according to claim 1, wherein said first connecting means comprises a first pipe coaxially disposed with the burner tube and surrounding its closed end, and said second connecting means comprises a second pipe coaxially disposed with the burner tube and surrounding said first pipe.
Claim 8
Dependent Claim
41 words
The power plant according to claim 1, wherein the burner tube includes a combustion zone towards its closed end and a mixing zone towards its open end, axial slits being provided between the said combustion zone and the said mixing zone.
Claim 9
Dependent Claim
34 words
The power plant according to claim 2, wherein said first connecting means comprises a first pipe and a first distributing tank, said firsT pipe being connected to the outer enclosure through said distributing tank.
Claim 10
Dependent Claim
41 words
The power plant according to claim 6, wherein the burner tube includes a combustion zone towards its closed end and a mixing zone towards its open end, axial slits being provided between the said combustion zone and the said mixing zone.
Claim 11
Dependent Claim
23 words
The power plant according to claim 1, wherein said compressor supplies air in parallel to the internal combustion engine and said combustion chamber.
