Abstract:
A method for flame treating or manufacturing a product, comprising the steps of:detachably coupling a flame jet forming ring to a body portion of a gas burner assembly, said flame jet forming ring generally fully enclosing a chamber that is at least partially defined within said body portion, said gas burner assembly including an air/gas inlet that communicates with said chamber, said flame jet forming ring including at least one port defined therein that communicates with said chamber; mounting said gas burner assembly on an end of arm tool; feeding an air/gas mixture into said chamber through said air/gas inlet to cause said air/gas mixture to be generally evenly distributed throughout said chamber and said at least one port, and to cause substantially all of said air/gas mixture to flow from said air/gas inlet to ambient atmosphere through said chamber and said at least one port; igniting said air/gas mixture to create a generally enclosed flame that projects from said gas burner assembly; moving said gas burner assembly with respect to a substrate while directing said generally enclosed flame towards the substrate, said flame jet forming ring being detachable from said body portion without removing said gas burner assembly from said end of arm tool.
