The present invention relates to a grate structure of an incinerator that can be extended to extend the operation time of the incinerator.

In general, wastes such as municipal waste are put into an incinerator, and then dried, burned, and burned in a stocker-type conveying apparatus including heat / wear-resistant metal grate disposed on the lower side of the incinerator.

Conventionally, the grate constituting such a stocker type conveying apparatus is burned by a lower space defined by the upper wall 1 and the left and right side walls 2 of the grate bar constituting the grate G, as shown in FIGS. 1A and 1B. At the same time the gas flow path R is formed, the combustion gas supplied through the flow path R of the combustion gas is in the incineration chamber to the front wall 3 extending to the upper wall 1 and the left and right both side walls 2. The opening part 31 for supplying a furnace is provided, and the rear end wall 4 is equipped with the mounting groove 41 which is fastened to the support rod 16 of a conveying apparatus. By arranging a plurality of grate lines formed in parallel in the width direction at the bottom of the incineration chamber at the bottom of the incineration chamber, the casing incineration treatment table of the conveying apparatus is configured.

One of the grate rows is mounted on the stationary frame 14 of the conveying device to form the stationary grate G1 row and the other adjacent grate row is mounted to the movable frame 15 of the conveying device to form the movable grate G2 row. These grate G1 and G2 rows are alternately arranged along the moving direction D of the garbage, and the movable frame 15 is moved back and forth in the horizontal direction by the reciprocating means (not shown) provided in the conveying apparatus. The reciprocating movement causes the lower end of the front wall 3 and the upper wall 1 of the rows of both gratings G1 and G2 to reciprocate. Accordingly, the waste 50 or the combustion products placed on the grate G row are pressurized by the shear wall 3 of the grate G and are conveyed in the conveying direction D. FIG.

However, in the grate made of conventional grate bars (incineration supports), chemicals generated by burning of industrial and environmental waste, such as lead oxide, vanadium ataxe, sulfuric acid, zinc oxide, etc., flow into the grate. The gap is lowered to fill the gap of the grate, and if the state persists, the air is supplied from the lower side of the incinerator and the incineration efficiency of the waste is significantly reduced because the air supplied from the lower side of the incinerator is not supplied as designed.
