Burner and method for the manufacture of synthetic quartz glass |
摘要 |
A burner for use in the manufacture of synthetic quartz glass is provided, which comprises a main burner (7) comprising a multi-tube assembly (1) including a center tube (2) for feeding a silica-forming compound, a first enclosure tube (3) surrounding the center tube for feeding a combustion-supporting gas, and a second enclosure tube (4) surrounding the first enclosure tube for feeding a combustible gas; a tubular shell (5) surrounding the multi-tube assembly for feeding a combustible gas; and a plurality of nozzles (6) disposed within the tubular shell for feeding a combustion-supporting gas. A double-tube assembly (8) is disposed so as to surround the forward opening of the main burner (7) for feeding a combustion-supporting gas. Synthetic quartz glass ingots having high optical homogeneity are produced by the method using said burner. <IMAGE> |
