An incineration grate includes several levels including first and second grate bars arranged in rows alongside one another and in rows one above another, forming step-shaped combustion surfaces with their upper supporting surfaces. At least once in an area of the upper supporting surfaces, the first grate bars form, over their width, a smaller supporting surface for fuel than that of the second grate bars via a first shoulder disposed inwards in a direction of a longitudinal center plane. In an area of the upper supporting surfaces, the second grate bars have a supporting surface with a larger width in order to form an overlap with the first grate bars via a second shoulder disposed outwards over the width of the first grate bars. The second grate bars have at least one pin configured to be introduced into a pocket in the first grate bars and increase the larger width.
