[0002] Currently, existing boiler tube bundle support structures generally use tube sheets 5, such as Figure 5 and Figure 6 As shown, the δ=16 support tube sheet has an opening of φ80. Since the tube sheet 5 is made of a single sheet of steel, the requirements for the tube sheet material are relatively high. The tube bundle installation is difficult, and the boiler tube bundle support method is limited. Furthermore, the existing boiler tube bundle support structure requires the entire tube bundle to be removed during replacement, which is inconvenient for disassembly and reassembly.

The base 1 is located below the boiler tube bundle, and multiple sleeves 2 are arranged horizontally side by side from top to bottom above the base 1. The number of sleeves 2 is consistent with the number of heating surface tubes 4 in each row of the boiler tube bundle. The multiple sleeves 2 are arranged coaxially with the multiple heating surface tubes. The heating surface tubes 4 to be supported are inserted into the inner holes of the sleeves 2, and two adjacent sleeves 2 are fixedly connected by sleeve connectors 3.

[0026] Specific Implementation Method Two: Combining Figures 1 to 4 This embodiment describes a sleeve connector 3 comprising two sleeve connecting plates. Two vertically symmetrically arranged sleeve connecting plates are positioned between two adjacent upper and lower sleeves 2, with their upper and lower ends welded to the two adjacent upper and lower sleeves 2, respectively. This configuration allows the sleeve connector 3 to effectively support the assembled sleeves 2 and the heated surface tube 4 inserted into the inner hole of the sleeves 2. Other components and connections are the same as in specific embodiment one.

[0027] In this embodiment, the sleeve connection plate is a steel plate.

[0028] Specific implementation method three: Combining Figures 1 to 4 In this embodiment, the two adjacent sleeves 2 are separated by a gap in the vertical direction. This arrangement ensures that the two adjacent sleeves 2 do not contact each other, allowing the weight of the upper sleeve 2 to be concentrated on the lower sleeve connecting plates, effectively improving support stability. Other components and connections are the same as in specific embodiments one or two.

[0029] Specific implementation method four: Combination Figures 1 to 4In this embodiment, the sleeve 2 has a length of 60mm. This design, by setting the length of the sleeve 2 to 60mm, facilitates the assembly between the heated surface tube 4 and the sleeve 2 while ensuring sufficient support area. Other components and connections are the same as in specific embodiments one, two, or three.

[0030] Specific Implementation Method Five: Combining Figures 1 to 4 This embodiment describes a base 1 comprising two first steel plates 101 and two second steel plates 102. The two first steel plates 101 are vertically and symmetrically arranged on the left and right sides of the bottom sleeve 2 along the axis of the sleeve 2. The top ends of the two first steel plates 101 are welded to the sleeve 2. The two second steel plates 102 are vertically arranged opposite each other between the two first steel plates 101, perpendicular to the first steel plates 101. Both ends of the second steel plates 102 are welded to the two first steel plates 101 respectively. This arrangement allows the two second steel plates 102 to connect and fix the two first steel plates 101. The two first steel plates 101 support the bottom sleeve 2. Other components and connections are the same as in specific embodiments one, two, three, or four.

[0031] In this embodiment, both the first steel plate 101 and the second steel plate 102 are steel plates.
