Abstract
Multi-flame burner wherein each flame is separated with respect to the neighbouring flame by at least one separating tube made of a heat resistant material, in particular quartz glass or ceramic material. The burner further comprises a plurality of co-axial pipes preferably made of a metallic material. The cross section of the upper end of the separating tube can be modified in order to increase the deposition rate of the burner. Also claimed are methods for manufacturing optical fibre preforms by vapour deposition using the multi-flame deposition burners.
