Abstract
Abstract An elongated burner, which produces a stream of metal oxide soot, comprises three adjacent housings. A centrally disposed housing contains a linear array of orifices for issuing a gas-oxygen mixture to produce a linear flame. Disposed on opposite sides of the central housing are two housings having orifices for issuing into the flame two linear streams of metal halide vapor. Gaps between the central and outer housings permit air to be aspired for stabilizing the flame. Additional flame stabilization may be achieved by providing a shield along the entire perimeter of the halide vapor streams to prevent the random aspiration of air into the sides of the flame.
