A porous silicon carbide insert is located in the burner and defines the burner head. This provides a larger area for the flame to attach to the burner head since the porous insert causes the gas/air mixture to flow from the entire burner head. A more stable flame results and the flame is unable to travel back into the burner venturi through the insert.

[ What is claimed is:] [1.] An inshot burner nozzle comprising:a venturi tube having an inlet for receiving gaseous fuel and atmospheric air and an enlarged outlet end;a burner insert having an inlet side and an outlet side defining an outer face and supported within said enlarged outlet end for creating a desired flame pattern;said burner insert comprising a porous ceramic silicon carbide material having a porosity of twenty pores per inch and a density of 0.30 to 0.50 grams per cubic centimeter such that said gaseous fuel and atmospheric air are distributed therein and emission of a gas/air mixture from said insert is at a slower velocity at said outer face of said insert than at said inlet side so as to provide a more stable flame due to the distribution.
