Abstract

A hybrid glass manufacturing furnace for supplying a unit for floating the glass on a molten metal bath, includes, from upstream to downstream: an electric melting zone with a cold-top including electrodes for melting a vitrifiable mixture in order to obtain a bath of glass; a refining and homogenizing zone with a hot-top, including a first convection loop and a second convection loop; and a zone for cooling the glass formed by a conditioning tank which, being passed through by the second convection loop, is connected to at least one flow channel, wherein the hybrid furnace includes at least one tank neck that includes a floor and connects the electric melting zone to the refining and homogenizing zone of the glass and the hybrid furnace includes a non-return separation device to prevent the molten glass in the refining and homogenizing zone from returning to the melting zone.
