Abstract
A glass furnace includes a furnace chamber for containing glass melt and a screw conveyor for receiving glass batch material and feeding the glass batch material to the furnace chamber. A dam wall is disposed with respect to the screw conveyor such that batch material from the screw conveyor must flow upward over the dam wall before entering the furnace chamber. The top of the dam wall may be below the level of the melt pool in the furnace chamber.
