ライドさせることにより吸収する構造を採用していた。2. Description of the Related Art When a suspended heat transfer tube is installed through a ceiling wall of a large boiler, FIGS. 6 and 7 (FIG. 6 shows a ceiling of a suspended heat transfer tube at the boiler ceiling). FIG. 7 is a side view of the wall penetrating portion, and FIG. 7 is a view seen from the line CC in FIG. Is provided, the connecting pipe 4 is extended above the ceiling wall penetrated between the ceiling wall pipes 1, and the connection pipe 4 and the ceiling wall pipe 1 are covered with a seal plate 8 and a sleeve 9. In addition, the contact portion between the connecting pipe 4 and the seal plate 8 is not welded, and the boiler is not operated without operating the boiler. The structure in which the difference in the amount was absorbed by freely sliding the connecting pipe 4 was adopted.

うことにより、燃焼排ガスがボイラの天井壁部分から外
部に漏れないようにしていた。Accordingly, the combustion exhaust gas in the boiler leaks to the outside (upward) from between the seal plate 8 and the connection pipe 4. However, the exhaust gas from the boiler is covered by covering the entire ceiling wall with a casing (not shown). It did not leak out of the wall.

多大の費用を要していた。In the structure of the conventional hanging-type heat transfer tube shown in FIGS. 6 and 7, the exhaust gas leaks to the upper part of the ceiling wall, so that a coal-fired boiler or the like is used. When a fuel that generates a large amount of dust in the combustion gas is used, a large amount of dust accumulates on the ceiling wall, and the periodic inspection of the boiler requires a great deal of cost to remove the accumulated dust. In addition, since the self-weight of the dust accumulated on the ceiling wall itself is added, it is necessary to form the ceiling wall firmly, which requires a great deal of cost.
【０００５】本発明の課題は、シールプレートとスリー

防止し得るボイラの吊り下げ伝熱管の支持構造を提供す
ることである。An object of the present invention is to provide a support structure for a suspended heat transfer tube of a boiler which can hermetically weld a seal plate, a sleeve, and a connection tube to prevent leakage of combustion exhaust gas.

接するボイラの吊り下げ伝熱管の支持構造である。The above object of the present invention is attained by the following constitution. That is, from a plurality of suspended heat transfer tubes provided inside the boiler, a connection pipe that penetrates a ceiling wall made of a membrane structure of the boiler and connects to a header of the heat transfer tube provided above the ceiling wall. In the support structure of the suspended heat transfer tubes of the boiler provided in each of the heat transfer tubes, a seal plate is provided for each connection tube at a portion where each connection tube passes through the ceiling wall, and the seal plate and the connection tube are directly or sleeved. This is a support structure for a suspended heat transfer tube of a boiler that is hermetically welded through a seal and the seal plate and the ceiling wall are hermetically welded through an expansion.

時とボイラ運転時における天井壁と接続管の上下方向の
伸び差は、エキスパンションで吸収することにより接続
管および天井壁に過大な応力を生じることなく、燃焼排
ガスの漏れを防ぐことができる。According to the present invention, the vertical expansion difference between the ceiling wall and the connecting pipe between the time when the boiler is not operated and the time when the boiler is not operated causes excessive stress to be applied to the connecting pipe and the ceiling wall by absorbing by expansion. Without this, leakage of the combustion exhaust gas can be prevented.

囲内とした構造をすることが望ましい。If the above-mentioned header is provided for every two rows of connecting pipes, the equipment cost is reduced. At this time, it is preferable that the horizontal spacing between the two rows of connection pipes and the header connected to the two rows of connection pipes be within a range that can support the weight of the suspended heat transfer pipe.

げ伝熱管の自重は接続管に加わらない。In addition, one header is provided for every two rows of connection pipes, and the connection pipe is bent, and a header and a seal plate through which two rows of connection pipes connected to the header are penetrated are provided. If the structure is supported by hanging rods installed between the two rows of connecting pipes, the connecting pipe 4 has a very flexible structure in the vertical direction, and the ceiling wall and the upper and lower parts of the connecting pipe in the cold can and during operation. It becomes easy to absorb the difference in elongation in the direction. In this case, the connecting pipes 4 cannot support the weight of the suspended heat transfer tubes 3. Therefore, if the connecting pipes 4 are supported on the two rows of seal plates by the hanging rods, the weight of the suspended heat transfer tubes will not be added to the connecting pipes.

それぞれ気密溶接されている。A seal plate 8 is provided at a portion where the connection pipe 4 passes through the ceiling wall 5, and the seal plate 8 is hermetically welded to a sleeve 9. The connection pipe 4 and the sleeve 9 are hermetically welded at the upper part of the sleeve 9. A metal expansion 10 is provided between the seal plate 8 and the ceiling wall 5, and the expansion 10 and the ceiling wall 5, and the expansion 10 and the seal plate 8 are hermetically welded, respectively.

The material of the connection pipe 4 is JIS-SUS304HTP,
The material of the sleeve 9 is JIS-SUS304TP.
The material of the weld between the seal plate 8 and the sleeve 9 is Inconel.

さらに大きくなる。Here, the temperature of the ceiling wall suspension bolt 11 is
During the boiler operation, the temperature is about 400 ° C., but the temperature of the connecting pipe 4 is about 500 to 550 ° C. by the tertiary superheater. Therefore, a difference in elongation occurs due to a temperature difference between the ceiling wall suspension bolt 11 and the connection pipe 4. When the boiler is started, the temperature rise of the ceiling wall suspension bolts 11 is slower than the temperature rise of the connection pipes 4 at the time of starting the boiler. The difference in elongation due to the difference is even greater.

合部での熱応力は小さい。This difference in elongation is absorbed by the expansion 10, so that the connection pipe 4, especially the connection between the connection pipe 4 and the header 6, the ceiling wall pipe 1 and the seal plate 8, and the connection between the seal plate 8 and the sleeve 9 are formed. Does not cause excessive thermal stress and can prevent fatigue damage of these members. Further, the material of the connection pipe 4 and the sleeve 9 are both SUS materials, and the linear expansion coefficients of the materials are the same.

低減することでコストダウンとなる。The embodiment shown in FIG. 3 differs from that shown in FIG. 2 in that one header 6 is provided for two rows of connection pipes 4. At this time, it is preferable that the horizontal spacing between the two rows of connection pipes and the header connected to the two rows of connection pipes be within a range that can support the weight of the suspended heat transfer pipe. Thus, the cost can be reduced by reducing the number of headers 6 to be installed.

４は強度上問題ない。In this case, the connecting pipe 4 is provided with three bends,
The structure is very flexible in the vertical direction. Therefore, the connecting pipe 4 cannot support the weight of the suspended heat transfer pipe 3. Therefore, the support plate 13 is attached to the two rows of seal plates 8.
And a central portion of the support plate 13 is suspended from the header 6 by a seal plate suspension bolt 14. In this structure, the weight of the suspended heat transfer tube 3 does not add to the connection tube 4,
The connection pipe 4 is added to the seal plate suspension bolt 14 and therefore has no problem in strength.

示す構造で問題ない。Further, in the examples shown in FIGS. 4 and 5, even when a temperature difference occurs between the connection pipes 4 adjacent to each other, since the connection pipes 4 are vertically flexible, the thermal stress acting on the connection pipes 4 or the seal plate 8 becomes small. No problem occurs. At the outlet side of the suspended heat transfer tube 3, the temperature difference between the adjacent connection tubes 4 may exceed 50 ° C., and in such a place, the structures shown in FIGS. 4 and 5 have many advantages. In addition, the pipe temperature difference between the adjacent connection pipes 4 is usually small on the inlet side of the fluid to be heated in the suspended heat transfer pipes 3, and there is no problem with the structure shown in FIG. 1, FIG. 2 or FIG.

きる。In the structure shown in FIGS. 4 and 5, since the seal plate hanging bolts 14 are installed between the two rows of the connecting pipes 4, the temperature of the seal plate hanging bolts 14 is relatively easy. The temperature of the connection pipe 4 can be followed, and the thermal stress of the connection pipe 4 caused by the temperature difference between the seal plate suspension bolt 14 and the connection pipe 4 can be suppressed to a small value.
