Abstract
A combustion apparatus for a refuse incinerator has a plurality of rows of grates arranged in parallel in the directions of breadth and in series in the longitudinal directions of a combustion zone and a post-combustion zone of the combustion apparatus. The rows consist of immobile grates and mobile grates alternately arranged. Immobile girders support the immobile grates. Mobile girders support the mobile grates. A partition wall divides the combustion apparatus into the combustion zone and the post-combustion zone. Seals cooperates with the mobile girders and are located on the partition wall. A hydraulic cylinder shuttles the mobile girders. Bearing housings are mounted on upper protrusions of the mobile girders holding the mobile grates so as to be able to vibrate. The engagement between the bearing housing and the mobile grates in the post-combustion zone allows play in the direction of driving the mobile girders so that the working stroke of the mobile grates in the post-combustion zone is shorter than the working stroke of the mobile grates in the combustion zone.
