ABSTRACT:
A hearth for use in a thermal processor or incinerator includes a substantially planar grate which is inclined upwardly and which is vibrated in such a way that material deposited on the input end of the grate moves upwardly toward the output end thereof. A dam in the form of a raised wall at the beginning of the grate prevents liquids and other materials from spilling off. A plurality of openings passing through the grate allow combustion air to pass therethrough from below. Located beneath the hearth is an ash bin in the form of a plenum which catches and accumulates ashes that fall through the air openings in the grate. Air forced into the plenum is used to clean out the ash by opening an outlet port at the end thereof.
