Abstract
A thrust grate, particularly a cooling or fire grate having an essentially horizontal sequence of two sets of grate plates alternatingly fixed and reciprocating forward and backward in linear alignment and vertically spaced from each other. Each set of plates has a rear portion extending in the direction of movement of the movable grate plates, an at least partially upward slanting front portion, and an inclined front. The front end of each plate overlaps the rear end of each following plate. The front ends of the fixed and reciprocating plates, each, are provided with a lip or nose, respectively, to move the material deposited on the sloped portions thereof. The angle of the sloped portion of the fixed grate plates is different from that of the movable grate plates. The rear portion of the plates with the smaller angle is positioned on a higher level than the rear portion of the plates with the larger angle slope. The combination of the features of the two plates permits a substantially horizontal movement of the thrust grates.
