ABSTRACT:
This invention relates to a burner apparatus (10) suitable for use in the flame attenuation of glass filaments. The flame attenuation burners of the prior art are subject to deleterious deposits of glass that have not been properly attenuated by the burner apparatus. These deposits usually form adjacent to the outlet opening (20) in the refractory material constituting the combustion chamber of the burner apparatus (10). In use, these deposits are removed by a mechanical process which tends to cause damage to the refractory material (12) of the burner apparatus (10). The present invention incorporates a metallic protector or a plate (22) having a discharge passageway (26) having an area slightly greater than the area of the outlet opening (20) and provides a means to protect the burner refractory material (12) from damage during mechanical removal of any glass deposits.
