Abstract

A gas burner nozzle made from tabular alumina mounted in a steel cup shaped support that operates at a high temperature and a high oxidation for use in fabricating glass products. The gas and fuel inlet ports terminating in a radiused exit that greatly reduces the noise common to devices of this sort. The burner has a cone shaped supplementary mixing chamber which, together with the improved gas and fuel exits and the reflecting ledge provides a smooth transition of the flame.

Claims

1. A gas burner comprising:

a cup shaped gas burner nozzle made of tabular alumina having a cone shaped mixing chamber terminating at one end in an end wall portion;

said gas burner nozzle having a flame retarding circumferential ledge on said one end, extending outwardly from said end wall portion, the outer edge of said flame retarding ledge having a circular cross-section;

said end wall portion having a plurality of equally spaced axial outlet ports therethrough, said axial outlet ports being spaced in a circular pattern parallel to the axial centerline of the burner;

said end wall portion further having a plurality of angular outlet ports therethrough, said angular outlet ports being spaced in a circular pattern at an outward angle of approximately 60 degrees in a radial direction to the axial centerline of the burner, the centerline of each of the exits of said angular outlet ports being spaced radially outward from and circumferentially centered between the centerlines of the exits of adjacent axial outlet ports, each of said exits of said angular and axial outlet ports terminating an enlarged diameter concave-radiused edge; and

,

the other end of the burner nozzle being axially retained in a steel cup-shaped support member with an inlet aperture at the center thereof.
