TAPERED PLUG BURNER CLEANING PORTS
First Claim
1. A method comprising:
- removing a tapered plug from a seat in an exterior portion of a burner to expose an access passage from a position outside a wall of a metal-melting furnace;
pushing a rod from outside the burner and outside the metal-melting furnace, in through the access passage exposed by removing the tapered plug, and toward or through an air passage extending between an interior of a body of the burner and an inside of the metal-melting furnace; and
dislodging, from the air passage and in response to movement of the rod toward or through the air passage, build-up of metal and/or oxide splashed from the metal-melting furnace and solidified in the air passage.

Abstract
A burner for a metal-melting furnace can releasably receive a tapered plug in sealing engagement with an access passage aligned with an air passage. The burner may be configured to extend through a wall of the metal-melting furnace so that the air passage is through a front face within the furnace and so that the access passage is through a rear face outside of the furnace. The access passage may be aligned with the air passage to permit a rigid structure to be passed through the burner from outside the furnace to dislodge build-up of solidified metal from the air passage. The tapered plug may be moveable between a sealing configuration of being received in a seat to seal the access passage during burner operation and a cleaning configuration of being removed from the seat to expose the access passage for insertion of the rigid structure.

7. A system comprising:
-
a top charge furnace comprising a wall bounding an inside of the top charge furnace; a burner extending through the wall and comprising a body defining; a front face within the inside of the top charge furnace; a rear face outside of the inside of the top charge furnace; an air passage through the front face; a fuel passage through the front face; and an access passage through the rear face and aligned with the air passage to permit a structure to be passed through the burner from outside the top charge furnace to clean out build-up of solidified metal and/or oxide from the air passage; and a tapered plug releasably received in the rear face and in sealing engagement with the access passage to seal off the access passage during operation of the burner. - View Dependent Claims (8, 9, 10, 11, 12)

13. A burner assembly comprising:
-
a body defining a chamber having a front face and a rear face; an air passage defined through the front face; a fuel passage defined through the front face; an access passage defined through the rear face and aligned with the air passage; a tapered seat forming an entrance to the access passage; and a tapered plug moveable between a sealing configuration and a cleaning configuration, the tapered plug in the sealing configuration being received in the tapered seat to seal the access passage during operation of the burner assembly, and the tapered plug in the cleaning configuration being removed from the tapered seat to expose the access passage and permit insertion of a rigid structure through the access passage to dislodge any blockage from the air passage. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
