FUEL-CONVEYING INCINERATION GRATE FOR INCINERATING PLANTS, ESPECIALLY FOR WASTE MATERIALS

摘要

In a fuel-conveying grate for incinerating plants, consisting of sections having a number of grate beams (1) extending obliquely downward in the direction of movement of the fuel, said beams having a grate top (4) stepped downwardly and being placed with lateral surfaces (3) closely adjacent to each other across the width of the grate, adjacent beams being reciprocable in the longitudinal direction, each beam being adapted for the passage therethrough of a heat-transmission medium, the main novel features are that immediately below the grate surface and in heat-transmitting contact with said surface and the lateral surfaces, longitudinally extending ducts (6, 7) for heat-transmission medium are provided. When heat-transmission medium is circulated through the ducts, temperature differences along the length of the beam are balanced, so that the difference in width between its two ends caused by temperature differences is minimized. In this manner, unwanted interspaces between adjacent beams are avoided.
