ABSTRACT:
A system for delivering a liquid reactant at high flow rates to an oxidation/flame hydrolysis glass soot deposition site. A first liquid only reactant is delivered to a flash vaporization chamber to form a thin film and mixed with oxygen after vaporization. Additional vaporized reactants are thereafter mixed with the vaporized first liquid prior to delivery to an oxidation/flame hydrolysis burner to form a glass soot outer cladding layer on a soot preform. The soot preform is subsequently fused to form a high quality glass blank for drawing into optical fiber.
