Abstract

A burner nozzle assembly includes a plurality of burner nozzles. Each burner nozzle includes an outer housing and a nozzle receivable within the outer housing. An air inlet conveys air into a first burner nozzle of the plurality of burner nozzles and a well product inlet conveys a well product into the first burner nozzle. An air transfer conduit interposes and fluidly couples the outer housing of adjacent burner nozzles and transfers the air from the first burner nozzle to subsequent burner nozzles of the plurality of burner nozzles, and a well product transfer conduit interposes and fluidly couples the outer housing of adjacent burner nozzles and transfers the well product from the first burner nozzle to subsequent burner nozzles.

First claim

The invention claimed is:

1. A burner nozzle assembly, comprising:
a plurality of burner nozzles, each burner nozzle including an outer housing and a nozzle received within an interior of the outer housing;
an air inlet that conveys air into a first burner nozzle of the plurality of burner nozzles;
a well product inlet that conveys a well product into the first burner nozzle of the plurality of burner nozzles;
an air transfer conduit interposing and fluidly coupling the outer housing of adjacent burner nozzles that transfers the air from the first burner nozzle to all subsequent burner nozzles; and
a well product transfer conduit interposing and fluidly coupling the outer housing of adjacent burner nozzles that transfers the well product from the first burner nozzle to all subsequent burner nozzles.

2. The burner nozzle assembly of claim 1 , wherein the outer housing of each burner nozzle, the air transfer conduit, and the well product transfer conduit cooperatively comprise a monolithic component part.

3. The burner nozzle assembly of claim 1 , further comprising cooling fins positioned at the air inlet.

4. The burner nozzle assembly of claim 1 , wherein each burner nozzle comprises:
an atomizer in fluid communication with the well product inlet;
one or more apertures defined in the nozzle; and
an atomizing chamber defined by the nozzle to receive a portion of the well product from the atomizer and a portion of the air via the one or more apertures to create an air/well product mixture.

5. The burner nozzle assembly of claim 4 , wherein at least one burner nozzle of the plurality of burner nozzles is movable between an open configuration that allows the portion of the air and the portion of the well product to enter the atomizing chamber to generate the air/well product mixture, and a closed configuration that ceases flow of the well product into the atomizing chamber while allowing flow of the well product to continue to a subsequent burner nozzle.

6. The burner nozzle assembly of claim 4 , wherein the atomizing chamber comprises an outlet, wherein the air/well product mixture is expelled from the atomizing chamber through the outlet to be burned.

7. The burner nozzle assembly of claim 4 , further comprising at least one pilot burner, wherein the at least one pilot burner generates a pilot flame which burns the air/well product mixture as it is expelled from at least one burner nozzle of the plurality of burner nozzles.

8. The burner nozzle assembly of claim 4 , wherein at least one burner nozzle of the plurality of burner nozzles comprises cooling fins positioned within the atomizing chamber.

9. The burner nozzle assembly of claim 5 , wherein the at least one burner nozzle comprises a piston received within the interior of the outer housing, wherein axial movement of the piston within the interior of the outer housing moves the at least one burner nozzle between the open configuration and the closed configuration.

10. The burner nozzle assembly of claim 6 , wherein a first burner nozzle of the plurality of burner nozzles is positioned adjacent to a second burner nozzle of the plurality of burner nozzles, wherein the first and second burner nozzles are positioned to allow the air/well product mixture expelled from the first burner nozzle to overlap with the air/well product mixture expelled from the second burner nozzle.

11. A method comprising:
conveying air and a well product to a first burner nozzle of a plurality of burner nozzles, wherein each burner nozzle of the plurality of burner nozzles comprises an outer housing that defines an internal cavity, a nozzle that is receivable within the internal cavity and that defines an atomizing chamber, and one or more apertures defined in the nozzle;
conveying a portion of the air, via an air transfer conduit, and a portion of the well product, via a well product transfer conduit, from the first burner nozzle to a second burner nozzle of the plurality of burner nozzles, wherein the air transfer conduit and the well product transfer conduit interpose and fluidly couple the outer housing of the first burner nozzle with the outer housing of the second burner nozzle;
moving the first burner nozzle to a closed configuration which blocks a flow of the well product into the atomizing chamber of the first burner nozzle; and
flowing air through the first burner nozzle to cool the first burner nozzle.

12. The method of claim 11 , wherein flowing air through the first burner nozzle comprises flowing air around the nozzle within the outer housing of the first burner nozzle, wherein air flowed around the nozzle within the outer housing of the first burner nozzle continues to flow through the air transfer conduit to the second burner nozzle.

13. The method of claim 11 , wherein flowing air through the first burner nozzle comprises flowing a metered amount of air through the one or more apertures and into the atomizing chamber of the first burner nozzle.

14. The method of claim 11 , further comprising moving the first burner nozzle to an open configuration which allows a flow of the air and the flow of the well product into the atomizing chamber of the first burner nozzle to generate an air/well product mixture.

15. The method of claim 11 , wherein the first burner nozzle comprises a piston received within the internal cavity of the outer housing of the first burner nozzle, wherein moving the first burner nozzle to the closed configuration comprises axially moving the piston within the internal cavity which blocks the flow of the well product into the atomizing chamber of the first burner nozzle.

16. The method of claim 14 , further comprising expelling, from the atomizing chamber of the first burner nozzle, the air/well product mixture.

17. The method of claim 16 , further comprising igniting the air/well product mixture.

18. A burner nozzle assembly, comprising:
a plurality of burner nozzles;
an air transfer conduit interposing and fluidly coupling an outer housing of a first burner nozzle of the plurality of burner nozzles with a second burner nozzle of the plurality of burner nozzles, wherein air flows from the first burner nozzle to the second burner nozzle through the air transfer conduit; and
a well product transfer conduit interposing and fluidly coupling the outer housing of the first burner nozzle with the second burner nozzle, wherein well product flows from the first burner nozzle to the second burner nozzle through the well product transfer conduit.

19. The burner nozzle assembly of claim 18 , further comprising:
an air inlet that conveys air into the first burner nozzle; and
a well product inlet that conveys the well product into the first burner nozzle.

20. The burner nozzle assembly of claim 18 , wherein at least one burner nozzle of the plurality of burner nozzles is movable between an open configuration, where a portion of the air and a portion of the well product enter an atomizing chamber of the at least one burner nozzle to generate an air/well product mixture, and a closed configuration, where a flow of the well product into the atomizing chamber ceases.
