Oxy-Fuel Burner for Glass Forehearths

Abstract:

A burner gas supply apparatus for increasing flame turbulence, the apparatus comprising a conduit having a characteristic width, W, defined by an inner surface having a circumferential direction and an axial direction, the axial direction terminating in a nozzle defining a nozzle exit plane and having a characteristic dimension, d, where d<=W; and three bluff bodies each with a characteristic dimension, D.sub.bb-i, projecting a length, L.sub.i into the conduit from the inner surface, and an axial spacing X.sub.i between adjacent bluff bodies (between the downstream bluff body and the nozzle exit plane in the case of X.sub.1) wherein 0.5<=L.sub.i/W<=1 and wherein X.sub.i/D.sub.bb-i<=30.
