Abstract
The present invention is directed to a method and apparatus for forming soot used in making glass, and in particular, optical waveguides. A liquid precursor ( ) is first fed into orifice ( ) of a liquid orifice insert ( ) within an injector ( ) positioned within an atomizing burner assembly, and is thereafter discharged from the injector into a pressurization chamber ( ). An atomization gas ( ) is also fed into the pressurization chamber ( ) to mix with the liquid precursor liquid stream ( ) which breaks into droplets ( ). The liquid precursor and atomization gas arm forced under pressure out of an atomization orifice ( ) on the face of the burner ( ) assembly. Flame gas ( ), reaction gas ( ) and shield gas ( ) are ejected from burner orifices ( and ) to produce the flame. The atomized liquid precursor thus discharged is fed into the flame ( ) produced at the face of the burner assembly where the atomized liquid precursor reacts with the flame to form soot ( ) on a rotating mandrel ( ).
