These grates cannot effectively control the air flow when the fuel is burning, resulting in serious heat loss and low thermal efficiency. In addition, the ash discharge of these grate devices is not smooth enough, which can easily cause grate blockage and affect the normal operation of the equipment.

[0004] In order to solve these problems, the utility model proposes a concave-convex tile type fixed grate device. The grate device includes a plurality of concave-convex fixed ends, each of which is an integrated type, including a convex fixed end and a concave fixed end. These concave-convex fixed ends are alternately connected in sequence to form a complete grate device, and grate bars are arranged on the convex fixed end and the concave fixed end, and ash discharge holes are formed between adjacent grate bars, so that the fuel can better contact with the air during combustion, thereby improving the combustion efficiency, and the ash discharge holes help to timely discharge the ashes after combustion.

[0005] The concave-convex tile-shaped fixed grate device of the utility model is made of corrosion-resistant and high-temperature resistant round steel or square steel, so that it can work stably for a long time in a high-temperature environment. At the same time, the length and width of the device can be adjusted according to actual needs, so that it can adapt to heat treatment needs of different scales. Utility Model Content
