Abstract: A furnace grate structure for a furnace or incinerator on which solid fuel advances in an advancing direction has at least two parallel grate beams extending substantially transversely to the advancing direction, the beams being mounted on a substructure and forming upwardly facing support structures. The grate beams form grate beam sections with gaps formed between the end surfaces of adjacent grate beam sections. The gaps are covered by a covering device and a recess is provided in the end surfaces of the grate beam sections to receive the covering device.

Abstract: A furnace grate structure for a furnace or incinerator on which solid fuel advances in an advancing direction has at least two parallel grate beams extending substantially transversely to the advancing direction, the beams being mounted on a substructure and forming upwardly facing support surfaces. A bank of elongated grate bars which extend substantially parallel to the advancing direction are supported on the upwardly facing support surfaces, and are spaced from each other. Each of the grate beams comprises a plurality of sections arranged end to end so that the length of the grate beams can be varied simply by changing the number of sections.

Abstract: An inclined furnace grate for an industrial furnace or incinerator with transverse grate beams supporting a downwardly stepped succession of banks of stationary and reciprocating grate bars, the grate beams having arranged in their supporting surfaces removable bearing pads of abrasion-resistant, alloyed cast iron for the sliding support and lateral positioning of the reciprocating grate bars, thereby protecting the softer cast iron grate beams against sliding wear and abrasion. The removable bearing pads are received inside shallow recessed seats and retained in place by the adjacent stationary grate bars.
