Kind Code:
A
Abstract:
To provide an apparatus for producing a high-quality porous glass capable of improving the productivity and reducing the amount of a glass raw material or a combustible gas used when depositing glass microparticles and producing the porous glass.
Plural burners 19 blowing glass microparticles on the lateral face of an axially rotated substrate glass rod 2 while repeating the reciprocation in the longitudinal direction of the substrate glass rod 2 are adjacently arranged and an exhaust hood 7 repeating reciprocation synchronously with the burners 19 is arranged above a porous glass preform 1 on which the glass microparticles are blown and successively deposited.
