ABSTRACT:
An apparatus and method for dewatering combined ash or other combustion related products. The apparatus aspects of the invention consist of a quench bath having a curved portion containing a plunger adapted to push combustion materials contained in the quench bath up an inclined trough. A vibrator is mounted below a portion of the inclined trough located above the waterline in the quench bath. As a result, material moved up the inclined portion is subject to vibration and compaction resulting in a substantial dewatering of the combustion material. The method of the present invention provides for the steps of quenching, moving and vibrating combustion by-products to obtain a dewatered material having reduced free water run-off.
