ABSTRACT:
A water-fillable trough receives the incineration residues from the drop shaft of a furnace. A partially water-fillable discharge chute slopes upwards from the trough and is provided at its upper end with an overflow edge. A reciprocatible piston conveys the incineration residue from the trough to a circulating device arranged in the discharge chute. The circulating device is in the form of a conveyor belt or a scraper chain and conveys the incineration residues through the discharge chute to the overflow edge. A shutting-off device for separating the chute from the trough is arranged above the transition point between the trough and the chute. The shutting-off device can be in the form of a slide provided with a hoist drive which passes through the upper wall of the chute, or a flap freely suspended by means of joints on the upper chute wall, or as a rubber apron freely suspended from the upper chute wall.
