Abstract:
A gas burner assembly, comprising:a body portion having a chamber at least partially defined therein, an air/gas inlet that communicates with said chamber, and an open end that communicates with said chamber; a flame jet forming ring that is detachably coupled to said body portion to generally fully enclose said chamber, said flame jet forming ring including at least one port defined therein that, when said flame jet forming ring is coupled to said body portion, communicates with said chamber and is disposed in a predetermined relationship with respect to a longitudinal axis of said body portion; a first coupling member that is adapted to detachably couple said flame jet forming ring to said body portion so that when an air/gas mixture is fed into said chamber through said air/gas inlet, said air/gas mixture is generally evenly distributed throughout said chamber and said at least one port, and substantially all of all said air/gas mixture flows from said air/gas inlet to ambient atmosphere through said chamber and said at least one port; wherein said at least one port forms a generally enclosed shape so that when an air/gas mixture is projected therefrom and ignited, a generally enclosed flame is projected from said burner assembly in a direction that is generally parallel to the longitudinal axis of said body portion; and a second coupling member that is adapted to detachably mount said gas burner assembly on an end of arm tool so that when said gas burner assembly is mounted on an end or arm tool and projects a flame therefrom, said gas burner assembly can be moved in a desired pattern over a substrate to flame treat the substrate, said flame jet forming ring being detachable from said body portion without removing said gas burner assembly from the end of arm tool.
