Summary:PCT No. PCT/EP93/02599 Sec. 371 Date Mar. 22, 1995 Sec. 102(e) Date Mar. 22, 1995 PCT Filed Sep. 24, 1993 PCT Pub. No. WO94/08191 PCT Pub. Date Apr. 14, 1994A grate element (1) for a grate surface, e.g. in a clinker cooler, is shaped in the form of a box between the walls (3, 4) of which a number of surface-defining grate bars (5, 6) are mutually arranged so that, between them, they form fine gas channels (7). The grate bars (5, 6) alternately consist of bars (5) having a substantially rectangular cross section and bars (6) having a cross section substantially of the form of an inverted T. The rectangular bars (5) overlap the transverse sections (6a) of the T-bars, each of which is provided at the free end with a projecting, longitudinal bead (17), whereas each of the rectangular bars (5) at the sides facing the T-bars (6) are correspondingly configured with depending, longitudinal beads (15). Hereby it is obtained that the grate element is effectively cooled, that the pressure loss through the grate element is appropriately large, that the grate element is protected against falling-through of material and that maintenance work in connection with the replacement of grate elements is facilitated.
