Abstract
A burner tip for passing fuel into a glass melting chamber having a fuel passageway and discrete cooling fluid passageways therein for cooling and shielding the burner tip from attack by a hostile gaseous chamber environment. A ceramic collar member is provided for minimizing inspirated air and cooling fluid may be passed through the burner tip during both the firing cycle and off-firing cycle. The burner tip is provided with small diameter cooling fluid passageways to establish a low volume, high velocity flow of cooling fluid sufficient to shield the burner tip from sting-out attack.
