ABSTRACT OF THE DISCLOSURE A grate wherein several steps of alternating partly overlapping mobile and stationary grate bars are adjacent to a compensating device which expands or contracts to compensate for heat-induced variations of the width of adjacent steps. The compensating device supports or is adjacent to a sealing device having auxiliary bars which abut against the side faces of adjacent mobile grate bars and abut against the top faces of adjacent stationary grate bars. The side faces of the stationary bars are separated form the sealing device and from the compensating device by permanent clearances which are overlapped by the auxiliary bars. The auxiliary bars rest on the stationary bars and are biased against the side faces of the respective mobile bars by weights or springs of the compensating device.
