ABSTRACT:
Disclosed is an apparatus for feeding and distributing charge material through a feeding opening onto the molten bath surface in a glass melting furnace. On a movable stand there are disposed a charge hopper, a charging device, a pusher with a pusher holder and pusher driver and a heat shield substantially covering the feed opening, in which at least one opening is disposed for the passage therethrough of the charging device and of the pusher holder. To maintain a suitable path of movement of the pusher with simultaneous improvement of the shielding action of the heat shield, the pusher holder is mounted on a horizontal linear guiding device on a horizontal platform and is displaceable with respect to the latter by a horizontal driver. The platform is mounted on the stand by means of a vertical guiding device and can be raised and lowered on the stand by a vertical driver. Thus it is possible to uncouple the driving movements and provide a better sealing of the places at which the pusher holder passes through the heat shield.
