Abstract

Claims (31)

1. A burner comprising:

a manifold elongated along an axis;

a plurality of nipples supported by the manifold; and

a jet supported by and protruding outwardly from each nipple, each jet including a fuel-combustion outlet;

the manifold including a first end that is open, a second end that is closed, and a wall extending from the first end to the second end;

each nipple having a first end that is open, a second end that is closed, and a wall extending from the first end of the nipple to the second end of the nipple;

each nipple being elongated transverse to the axis at the first end of the nipple;

the manifold having an inner diameter and each nipple having an inner diameter at the manifold that is smaller than the inner diameter of the manifold at the respective nipple;

each nipple having an outer diameter at the manifold that is smaller than the inner diameter of the manifold; and

each jet having an inner diameter at the respective nipple that is smaller than the inner diameter of the respective nipple at the respective jet.

2. The burner as set forth in claim 1 , wherein, for each jet, the inner diameter of the jet expands from the respective nipple to the respective fuel-combustion outlet.

3. The burner as set forth in claim 1 , wherein each jet has threads threadedly engaged with the respective nipple.

4. The burner as set forth in claim 1 , wherein each jet has an outer diameter at the respective nipple that is smaller than the inner diameter of the respective nipple at the respective jet.

5. The burner as set forth in claim 1 , wherein each jet is elongated from the nipple to the fuel-combustion opening.

6. The burner as set forth in claim 1 , wherein the jets each have an annular cross-section.

7. The burner as set forth in claim 1 , wherein the first end of the manifold, the second end of the manifold, and the wall of the manifold are unitary.

8. The burner as set forth in claim 1 , wherein the manifold is straight from the first end of the manifold to the second end of the manifold.

9. The burner as set forth in claim 1 , wherein the manifold has an outer diameter and the outer diameter of the nipple at the manifold is smaller than the outer diameter of the manifold at the respective nipple.

10. The burner as set forth in claim 1 , wherein the inner diameter of the manifold is between 0.59-0.61 inches.

11. The burner as set forth in claim 1 , wherein the inner diameter of the manifold is constant from the first end of the manifold to the second end of the manifold.

12. The burner as set forth in claim 11 , wherein, for each nipple, the inner diameter of the nipple is constant from the first end of the nipple to the second end of the nipple.

13. The burner as set forth in claim 12 , wherein, for each jet, the inner diameter of the jet expands from the respective nipple to the respective fuel-combustion outlet.

14. The burner as set forth in claim 1 , wherein each nipple has threads at the first end of the nipple, and the manifold includes threaded holes threadedly engaged with the threads on the first ends of the nipples.

15. The burner as set forth in claim 14 , wherein the first end of the nipple, the second end of the nipple, and the wall of the nipple are unitary.

16. The burner as set forth in claim 15 , wherein each nipple has flats at the second end of the nipple, the flats being arranged circumferentially about the second end of the nipple.

17. The burner as set forth in claim 14 , wherein at least some of the threaded holes of the manifold are spaced from each other along the axis and at least some of the threaded holes of the manifold are aligned with each other along the axis.

18. The burner as set forth in claim 14 , wherein the nipple has an outer diameter of 0.54 inches and the threads of the nipple taper and have a pitch of 18 threads per inch.

19. The burner as set forth in claim 1 , wherein the first end of the nipple, the second end of the nipple, and the wall of the nipple are unitary.

20. The burner as set forth in claim 1 , wherein all of the nipples are in a common plane.

21. The burner as set forth in claim 1 , wherein at least one nipple extends in one direction perpendicular to the axis and at least one nipple extends in an opposite direction perpendicular to the axis.

22. The burner as set forth in claim 1 , wherein the manifold is annular in cross-section and the nipples are annular in cross-section.
