A movable grate comprises a number of steps which are arranged close to one another so they partly overlap one another and can be tilted about an axis extending in the longitudinal direction of the grate step, and which are tiltably mounted outside shield members 7, 10 which in the lateral direction enclose a combustion chamber. End plates 5 are rigidly secured to the ends of the grate steps and are tiltable therewith, the end plates being aligned with and fitted in openings in the shield members. The novelty of the invention resides in the fact that portions 10 of the shield members having such openings aligned with the end plates 5 are displaceably mounted relative to adjacent shield members 7 in the direction of the grate step axis, and that the shield portions 10, which are externally connected in a sealed manner to shield members 7 and internally connected in a sealed manner to end plates 5, are, in the direction of said axis, rigidly secured to the grate step shaft. <IMAGE>
