Teske, L

A ash-removal conveyor used in combination with an ash-quenching trough has a drive wheel above and spaced from the trough, horizontally spaced reversing and guide wheels in the trough below the liquid level therein, and an endless conveyor chain spanned over the wheels and having a horizontal lower stretch extending between the reversing and guide wheels, an inclined lower stretch extending between the guide and drive wheels, and an at least partially inclined upper stretch extending between the reversing and drive wheel. The drive wheels are tensioned away from the other wheels and to tension the belt. A drive connected to the drive wheel moves the chain to pick up ash in the trough and conduct the picked-up ash from the trough. The conveyor has a floor immediately beneath and extending along the upper stretch between the reversing and drive wheels and above the lower stretches. The drive means moves the chain in a direction to pick up ash with the horizontal lower stretch and convey it away along the floor with the upper stretch.
