Incineration grate consisting of grate bars and method for fitting grate bars in and removing same from an incineration grate

A method for installing and removing grate bars into and from an incineration grate comprising a plurality of grate bars arranged in rows alongside one another and in rows one above another, the grate bars including first grate bars and second grate bars having upper supporting surfaces and adjacent connecting surfaces, the method comprising:

• forming a step-shaped combustion surface over a width of the incineration grate using the upper supporting surfaces of the first grate bars and second grate bars, which are mounted on one side with a support on a grate rod, wherein, at least once, over their width, the first grate bars form a supporting surface for fuel that is smaller than that of the second grate bars via a first shoulder disposed inwards in a direction of a longitudinal center plane, and wherein, 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,
• wherein adjacent to and/or bordering the connecting surfaces, only the second grate bars comprise at least one pin configured to further increase the larger width, the pin configured to be introduced into a corresponding pocket in the first grate bars,
• wherein the pin comprises a projection that projects outward from a surface of a respective second grate bar,
• wherein for removal, a second grate bar on a side of the support is lifted from the grate rod far enough so that the second grate bar can be slid along the longitudinal center plane in order to remove the pin from the pocket of adjacent first grate bars, and
• wherein a reverse sequence is used for installing the second grate bar.
