Abstract
Abstract Residual gas burner composed of a smoke-evacuating conduit at the base of which are disposed several superposed combustion chambers coaxial to said conduit, of volume increasing upwardly; each chamber comprises at least one peripheral gas burner and the device comprises means for measuring the total outflow of the residual gases and means for automatically supplying residual gases to a number of burners, counting from the lower burner, varying in the same way than the outflow of gases. The burner according to the invention is more particularly applicable to burning residual effluents from oil-refineries.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
195 words
A DEVICE FOR BURNING RESIDUAL GASES COMPRISING A PLURALITY OF VERTICALLY SUPERPOSED, OPEN-ENDED, CO-AXIAL TUBES, EACH VERTICALLY SUCCESSIVE TUBE HAVING AN INTERIOR VOLUME GREATER THAN THE INTERIOR VOLUME OF THE TUBE NEXT BELOW TO FORM A PLURALITY OF VERTICALLY SUPERPOSED CHAMBERS OF SUCCESSIVELY GREATER VOLUME, THE UPPERMOST TUBE OPENING UPWARDLY AND THE UPPER END OF EACH OTHER TUBE OPENING INTO THE LOWER END OF THE TUBE NEXT ABOVE, EACH TUBE ALSO HAVING AT LEAST A PORTION OF THE LOWER END THEREOF SPACED FROM THE UPPER END OF THE TUBE NEXT BELOW TO PROVIDE AIR PASSAGEWAYS BETWEEN EACH PAIR OF TUBES, A PLURALITY OF RESIDUAL GAS BURNERS, AT LEAST ONE AT THE LOWER PORTION OF EACH TUBE AND EXTENDING AROUND THE AXIS THEREOF, MEANS FOR SUPPLYING SAID RESIDUAL GASES TO SAID BURNERS INCLUDING CONTROL MEANS FOR SELECTIVELY SUPPLYING SAID RESIDUAL GASES TO EACH SAID BURNER, MEANS FOR MEASURING THE FLOW OF SAID RESIDUAL GASES IN SAID SUPPLYING MEANS AND OPERATING MEANS RESPONSIVE TO SAID MEASURING MEANS AND CONNECTED TO SAID CONTROL MEANS FOR INCREASING THE NUMBER OF SAID BURNERS TO WHICH SAID RESIDUAL GASES ARE SUPPLIED WITH AN INCREASE IN SAID FLOW OF SAID RESIDUAL GASES.
Claim 2
Independent Claim

Claim 3
Dependent Claim
32 words
A device as set forth in claim 1, wherein the control means for the lowermost one of said burners is continuously open to continuously supply said residual gases to said lowermost burner.
Claim 4
Dependent Claim
31 words
A device as set forth in claim 1, further comprising means for automatically igniting the residual gases supplied to the lowermost one of said burners when such gases are supplied thereto.
Claim 5
Dependent Claim
30 words
A device as set forth in claim 1, wherein said operating means successively operates the control means of successively higher burners with increases in said flow of said residual gases.
Claim 6
Dependent Claim
87 words
A device as set forth in claim 1, further comprising a vertically extending conduit extending around said tubes, said conduit having a vertical height greater than the vertical height of said superposed tubes and having an opening at the top thereof for evacuating burned gases, said superposed tubes being disposed at the lower interior portion of said conduit with a plurality thereof spaced from said conduit and said conduit having at least one opening at the bottom thereof for the supply of combustion air to said tubes.
Claim 7
Dependent Claim
67 words
A device as set forth in claim 5, wherein each tube is a hollow cylinder and each successively higher tube has a diameter and height greater than the diameter and height of the tube next below and wherein the bottom of each tube is at substantially the same level as the top of the tube next below to provide said air passageways between each pair of tubes.
Claim 8
Dependent Claim
23 words
A device as set forth in claim 5, wherein each of said tubes is in the shape of an upwardly widening conical frustum.
Claim 9
Dependent Claim
76 words
A device as set forth in claim 7, wherein the diameter of the lower end of each successive tube is substantially equal to the diameter of the upper end of the next lower tube and is joined with the latter with portions thereof spaced from the next lower tube to provide said air passageways and wherein said gas burners are ring shaped pipes having radially inwardly directed perforations for the passage of said residual gases therethrough.
Claim 10
Dependent Claim
37 words
A device as set forth in claim 8, wherein said tubes are made of a refractory material and wherein said lower end of each tube has said portions thereof bent outWardly from the axis of the tube.
Claim 11
Dependent Claim
75 words
A device as set forth in claim 7, wherein the diameter of the lower end of each successive tube is greater than the diameter of the upper end of the next lower tube to provide said air passageways between said tubes and said gas burners are ring shaped pipes having upwardly directed perforations therein for the passage of said residual gases therethrough and wherein each said burner is disposed in one of said air passageways.
Claim 12
Dependent Claim
27 words
A device as set forth in claim 5, further comprising means for injecting water vapor into at least one of said residual gases and said combustion air.
