Furnace has a melting section and a withdrawal section bounded by side walls of refractory material which extend to a glass outlet formed by an overflow edge remote from the melting section. In operation a molten glass layer, a molten layer of undissolved sulfates, and a batch layer succeed one another from the bottom up in the melting section. The withdrawal section is separated from the melting section by a first dividing wall extending downwardly and terminating above the surface of the molten glass. A second dividing wall is disposed for the formation of an underside glass passage, and at least one closable opening for withdrawing the molten sulfates is disposed at the level of the sulfate layer between the first and second dividing walls. The opening has a bottom boundary whose height is adjustable, so that it can be adjusted to lie above the surface of the glass melt.

摘要:
A glass melting furnace having a melting section and an adjacent refining section. The two sections are interconnected by a step or barrier which reduces the cross-sectional area of the furnace. The refining section has at least one plane of a plurality of electrodes immersed in the molten glass mass thru which energy is supplied to the molten glass mass. A refining zone is positioned below the region containing the electrodes from which refined glass is discharged thru an outlet therein.

摘要:
The present invention provides a method of melting glass, whereby in a glass melting furnace having electrodes positioned in a plurality of levels or planes the glass is melted in a vertical passage and thereafter discharged via an outlet passage at the bottom of the furnace, while the glass stream, after its upward flow, flows vertically downwards under mechanical agitation, thereafter to flow upwards for further processing or treatment. The glass stream may be additionally heated by electrical energy during its upward flow prior to the agitation.
