Abstract

A burner, comprising: an oxygen supply tube and a burner tip defining a concave face; wherein the burner tip defines a main oxygen nozzle having a parabolic shape.

Claims (20)

1. A burner for use in a metallurgical furnace, the burner comprising:

an oxygen supply tube;

a burner tip having a first end and a second end, the second end defining an outermost face of the burner tip, wherein the burner tip is removably attached to the oxygen supply tube at the first end of the burner tip, the burner tip further comprising:

an outer diameter and a length, wherein the outer diameter of the burner tip is tapered along the length of the burner tip;

a concave face at the second end of the burner tip;

an oxygen nozzle having a parabolic shape and being disposed in the concave face of the burner tip; and

a plurality of fuel supply ports each having a v-shape and being both disposed in the concave face of the burner tip and radially disposed around the oxygen nozzle;

wherein the outer diameter of the burner tip decreases along the length of the burner tip in a direction from the first end of the burner tip to the second end of the burner tip; and

wherein the concave face is substantially perpendicular to the length of the burner tip.

2. The burner of claim 1 , wherein the concave face is completely defined within the outer diameter at the second end of the burner tip.

3. The burner of claim 1 , wherein the burner is water-cooled.

4. The burner of claim 1 , the burner further comprising at least eight fuel supply ports.

5. The burner of claim 1 , the burner further comprising a groove disposed in the concave face and radially disposed around the fuel supply ports.

6. The burner of claim 1 , wherein the oxygen nozzle is centrally disposed in the concave face.

7. The burner of claim 1 , the oxygen supply tube further comprising an outer diameter, wherein the outer diameter of the first end of the burner tip is greater than the outer diameter of the oxygen supply tube.

8. The burner of claim 1 , further comprising an ignitor.

9. The burner of claim 1 , wherein the fuel supply ports are natural gas fuel supply ports.

10. The burner of claim 1 , wherein the burner tip is substantially cylindrical.

11. The burner of claim 1 , the oxygen supply tube further comprising a length, and wherein the length of the oxygen supply tube is at least two times as long as the length of the burner tip.

12. The burner of claim 1 , wherein the metallurgical furnace is an electric arc furnace or a blast furnace.
