[0009] The sealing box is welded with the sealing cover.

[0010] It includes main pipe and multiple wall-penetrating pipes, the main pipe is arranged in sealing cover, the multiple wall-penetrating pipes are communicated with the main pipe respectively, and another end passes through the sealing cover, sealing box and wall.

[0011] The multiple wall-penetrating pipes are arranged in equal intervals along horizontal direction.

[0012] The sealing cover is provided with notch, the sealing box is inserted into the notch, and the notch is sealed with the sealing box.

[0013] Beneficial effects are:

[0014] The superheated through-wall tube device comprises a wall, a header pipe seat arranged on the wall, a through-wall tube and a sealing box, one end of the through-wall tube is welded and fixed with the header pipe seat, the sealing box is arranged, one part of the sealing box is fixed on the header pipe seat, and the other part of the sealing box protrudes from the wall, the through-wall tube is welded with the header pipe seat through the sealing box, and the sealing box is filled with high-aluminum refractory castable.

[0015] 1. The sealing box can effectively prevent steam leakage at the header pipe seat of the superheater, and the broken header pipe seat and the through-wall tube can cause the working steam to leak out, which not only affects the normal operation of the boiler, but also may pollute the environment. The sealing box ensures that the steam in the through-wall tube at the header pipe seat will not leak out due to its good sealing performance, thereby ensuring the safe operation of the boiler.

[0016] 2. Corrosion is reduced: the sealing box is filled with high-aluminum refractory castable, the high-aluminum castable not only has excellent heat insulation performance, but also can enhance the sealing between the sealing box and the through-wall tube, effectively preventing air from entering; since the sealing box can effectively isolate external air and moisture, the contact between the broken pipe seat and corrosive substances can be reduced, thereby reducing the degree of corrosion and prolonging the service life of the superheated through-wall tube and the header.

[0017] 3. Strengthen the structure: the sealing box reinforces the structure of the header pipe seat, which can reduce further damage caused by stress changes. It can disperse and alleviate the stress concentration phenomenon at the header pipe seat, thereby reducing the risk of header pipe seat fracture.

[0018] 4. The superheater header is provided with a sealing cover filled with aluminum silicate fiber cotton, which is welded with the sealing box to ensure its stability during operation, and it effectively transfers the stress originally concentrated between the sealing box and the through-wall tube. Through such stress transfer, the through-wall tube can freely expand during operation without being restricted and damaged by stress concentration.

[0019] 5. By welding the sealing cover, the sealing between the sealing box and the sealing box is significantly improved, which not only effectively prevents air from entering and reduces heat loss, but also further enhances the safety and operating efficiency of the boiler system.
