Abstract
A method and apparatus for incinerating combustible materials wherein the movement of the material particles is controlled as they are moved over an arrangement of grate sections during combustion in relation to particle density so that less dense particles travel faster than more dense particles to provide for increased combustion efficiency. The grate sections are arranged in adjacent groups and in an alined, downstepped succession. Each grate section has a downwardly inclined, upper support surface and a reciprocating pusher block is moved an adjustable distance over an inlet end portion of the upper support surface of each pusher block to impart moving forces through the material in a pushing stroke that is substantially shorter than the full travel distance of the material along the associated grate section. An adjustable speed, reversible drive is coupled to the pusher blocks so as to provide related, opposite, reciprocating movement of adjacent pusher blocks and related in-phase movement of a succession of alined pusher blocks. An escapement coupling between each pusher block and an associated grate section provides for limited reciprocating movement of each grate section, a…
