Abstract
An inshot burner (10) includes an axially elongated tubular nozzle (40) having a flared inlet end (42), a cylindrical outlet end (44) and a venturi section (46) therebetween. A burner head insert (20) is disposed within the cylindrical outlet end 44. The burner head insert (20) has an axially elongated annular body (22) having an axially extending inner flow passage (25) passing therethrough and a plurality of circumferentially spaced, axially extending splines (30) radiating outwardly therefrom toward the surrounding wall of the outlet end (44) of the burner tube. A plurality of second flow passages (35) are defined between the plurality of splines (30). Each of the axially extending splines (30) has a cross width which enlarges in the axial direction from the inlet end of the burner head insert to the outlet end of the burner head insert.
