Abstract
A stepped grate-type cooler of the type employing a plurality of spaced grate plate carriers, alternate carriers being stationary and the carriers positioned between the stationary carriers being reciprocable relative thereto. Each of the grate plate carriers includes transversely extending carrier beams with carrier fingers extending therefrom. A plurality of grate plates is carried by each of the carrier fingers, and the clearance between the stationary carrier beam and a reciprocable carrier beam is greater than the width of each of the grate plates in a region extending from the mid position of the reciprocable carriers to either extreme end of the reciprocation travel of the carriers. With this type of structure, it is considerably more convenient to remove individual grate plates since this can be accomplished from the bottom rather than going through the hot gases in the cooler.
