Abstract
A burner assembly for heating a U-shaped radiant tube. The burner assembly includes a generally conical burner nozzle supported on the end of a gas supply pipe and disposed within an inner tube which, in turn, is located within the radiant tube. The burner nozzle may be adjusted selectively back and forth within the inner tube to change the ratio of primary and secondary combustion air supplied to the nozzle and thereby change the length of the flame produced by the burner assembly.
