[0022] like Figures 1 to 5 As shown, this embodiment discloses a flue wall structure of a carbon roasting furnace, comprising a plurality of flue wall bodies 1, wherein the plurality of flue wall bodies 1 are arranged side by side along the width direction of the flue wall bodies 1; among the plurality of flue wall bodies 1, every two flue wall bodies form a flue wall assembly, and a roasting furnace material box is formed between adjacent flue wall assemblies;

The tops of the first positioning block 4 and the second positioning block 5 are both connected to the bottom of the furnace surface block 2. The first positioning block 4, the second positioning block 5, the upper end surface of the support cover plate 3, and the lower end surface of the furnace surface block 4 together form a closed cavity, and the closed cavity is filled with a fiber blanket 6, and the fiber blanket 6 is a zirconium-containing fiber blanket.

[0025] During assembly, a cavity structure is formed by the support cover plate, the first positioning block and the second positioning block, and then the fiber blanket is filled into the cavity.

[0026] The support cover plate 3 is arranged in a rectangular plate shape, and two first limiting protrusions 301 are symmetrically arranged at the bottom end of the support cover plate 3, and the two first limiting protrusions 301 are arranged corresponding to the first limiting grooves 102 arranged at the top ends of the two fire channel wall bodies 1; when the support cover plate 3 is connected to the top ends of the two fire channel wall bodies 1, the first limiting protrusion 301 is embedded in the first limiting groove 102; the top end of the support cover plate 3 is symmetrically arranged with two second limiting protrusions 302 and is connected to the first positioning block 4 and the second positioning block 5 through the second limiting protrusions 302.

[0027] The first positioning block 4 and the second positioning block 5 are both provided with a second limiting groove 401 at the bottom end, and the two second limiting grooves 401 are respectively provided corresponding to the two second limiting protrusions 302; when the first positioning block 4 and the second positioning block 5 are connected to the top end of the support cover plate 3, the second limiting protrusion 302 is embedded in the corresponding second limiting groove 401; the first positioning block 4 and the second positioning block 5 are both provided with a third limiting groove 402 at the top end and are connected to the furnace surface block 2 through the third limiting groove 402.

The two third limiting protrusions 211 are respectively arranged corresponding to the third limiting grooves 402 at the top ends of the first positioning block 4 and the second positioning block 5; when the first positioning block 4 and the second positioning block 5 are connected to the stove surface block 2, the third limiting protrusion 211 is embedded in the third limiting groove 402.
