A burner system for a furnace (10) includes an in-shot burner (20) having an axially elongated tubular nozzle (40) having an inlet end (42), an outlet end (44) and a venturi transition section (46) therebetween. At least a portion of a catalyst body (50) is disposed within the outlet end (44) of the burner (40). The catalyst body (50) supports a partial oxidization catalyst operative to catalyze the fuel in the primary air/fuel mixture to intermediate combustion species, including hydrogen and carbon monoxide, thereby reducing emissions such as nitrogen oxides.

[ What is claimed is:] [1.] A combustion system for use in a fuel-fired apparatus comprising:a fuel-fired burner having an outlet section, said burner operative for generating a primary air and fuel mixture within said outlet section and generating a flame extending substantially downstream from a flame front formed downstream from said outlet section;a burner insert including a catalyst body for oxidizing at least a portion of the fuel in the primary air and fuel mixture into intermediate combustion species, at least a substantial portion of said catalyst body being disposed upstream of the flame front; anda heat transfer member extending from said catalyst body in a downstream direction beyond said outlet section into the flame.
