A furnace feed grate of an incinerator comprises transverse rows of grate blocks, the blocks of alternate rows being movable to feed refuse along the grate. Clamping devices at the underside of the grate resiliently urge together the blocks of the respective rows. At the lateral edges of the grate, sealing plates are resiliently urged into sealing contact with the ends of the rows independently of the action of the clamping devices. The grate, the clamping devices and the sealing plates can be removed from the incinerator as a single unit.
