    Abstract: PURPOSE: Provided are a burner for synthesizing glass particles which is a concentric multi-tubular burner easy to be manufactured, which is high in efficiency of mixture among raw material gas, combustion-support gas and combustible gas, and which can obtain a high raw material yield, and a method for producing the porous glass body by use of the burner. CONSTITUTION: The concentric multi-tubular burner for synthesizing glass particles, comprises a center port group(5) including: a raw material gas jet port(1); a combustible gas jet port; and an oxygen gas jet port(4) disposed outside the raw material gas jet port and combustible gas jet port. An outer wall of the oxygen gas jet port of the center port group more protrudes toward a head of the burner than an inner wall of the oxygen gas jet port, and a protruding length of the outer wall is not shorter than 30 times as large as a gap between an inner surface of the outer wall and an outer surface of the inner wall of the oxygen gas jet port.

    Abstract: PURPOSE: To provide a method for producing an accumulated body of fine glass particles in high yield at a high rate by VAD method. CONSTITUTION: The method for producing the accumulated body of fine glass particles pulls a target glass rod comprising a core and a clad while accumulating the fine glass particles on the periphery of the rod by a vapor phase axial deposition method (VAD). A porous glass body is accumulated on the outside of the glass rod with a primary burner and further an accumulated body of the fine glass particles is accumulated on the outside of the porous glass body with a secondary burner. The method is characterized in that 1 the diameter of the accumulated body of the fine glass particle formed with the primary burner is 2 times or more and 5 times or less of that of the glass rod, and 2 the thickness of the accumulated body of the fine glass particles formed with the secondary burner is 1.5 times or more and 7 times or less of that of the accumulated body of the fine glass particles formed with the first burner.
