ABSTRACT:
An elongated burner for producing a stream of metal oxide soot comprises a burner face having two parallel arrays of orifices for issuing a gas-oxygen mixture to produce two intersecting linear flames. Disposed between the gas-oxygen orifices is an array of orifices for issuing metal halide vapor into the flame. Two parallel arrays of orifices, one on each side of the vapor orifices and closely spaced therewith provide high velocity jets of inner shield gas on opposite sides of the vapor streams. Disposed between the inner shield gas orifices and the gas-oxygen orifices are two elongated slots which are much greater in width than the diameters of the aforementioned orifices. These slots provide a large volume, low pressure dry, nonreactive gas which prevents the flame from "backsplashing" onto the region of the vapor orifices and further prevents the deposition of soot on the burner face.
