FIELD: chemistry.
SUBSTANCE: invention relates to field of glass manufacturing, in particular, to glass manufacturing furnaces. Waveguide for glass mass lightening, which includes submerged into glass mass melt cylindrical case of waveguide with closed butt end, is provided with gas jet acoustic emitter pipeline for supply and discharge of working gas, inbuilt inside waveguide case cylindrical perforated with holes cylindrical tube with closed butt end. Axes of perforation holes are perpendicular to internal surface of waveguide case. Clearance between internal surface of waveguide case and external surface of perforated tube constitutes value h=6dh, where dh is diameter of perforated tube holes.
EFFECT: ensuring intensification of removal of gas bubblers from glass mass volume in zone of lightening, which leads to increase of productivity of glass manufacturing furnaces with increase of resource of waveguide work in high-temperature glass mass medium.
