Abstract

PURPOSE:To obtain a stable base material for optical fibers with prevented fluctuation of flames, by means of a cylindrical body elongated from the tip outer periphery of a multitubular burner further and an apparatus for heating the inner wall surface of the cylindrical body. CONSTITUTION:A hood 11 as a cylinrical body elongating further from the tip of a burner 1 is provided at the tip of the burner 1 with a spacer 10. A material, e.g. zirconia, having a high melting point, improved corrosion resistance and high thermal shock resistance is used as the material of the hood 11. A heating apparatus 12 is provided on the outside of the hood 11 for heating the inner wall surface (11a) of the hood 11 at a high temperature. A heating apparaus utilizing the high-frequency induction heating is used as the heating apparatus 12, and a high-frequency working coil 13 is provided therein.
