本発明はガスタービン排ガスボイラー、各種排
ガス熱交換器に用いられる排ガス熱交換器に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an exhaust gas heat exchanger used in a gas turbine exhaust gas boiler and various exhaust gas heat exchangers.
最近、燃料資源の節約から高効率な発電プラン
ト及び熱交換器が要求されるようになり、ガスタ
ービンの排ガス及び溶鋼炉排ガス等を再利用する
大型排ガスボイラー及び熱交換器が開発されつつ
ある。 Recently, there has been a demand for highly efficient power generation plants and heat exchangers to conserve fuel resources, and large-scale exhaust gas boilers and heat exchangers that reuse gas turbine exhaust gas, melting furnace exhaust gas, etc. are being developed.
排ガス熱交換器としては、加熱管を略水平方向
に配置し、ガスを垂直方向に流すガス縦流れ方式
と加熱管を略垂直に配置し、ガスを水平方向に流
すガス横流れ方式に区分される。 Exhaust gas heat exchangers are divided into vertical gas flow systems, in which the heating tubes are arranged approximately horizontally and the gas flows vertically, and horizontal gas flow systems, in which the heating tubes are arranged approximately vertically, and the gas flows horizontally. .
従来公知の排ガス熱交換器としては、ガス縦流
れ方式が多く、ガス横流れ方式の例は少ない。ま
た、上記の如く開発途上のものであり、比較的小
型の熱交換器が多く、この場合は、ガスダクト内
に加熱管が装備された程度で、地震等による水平
力も小さいことから、本格的な耐震設計となつて
いない。また、比較的大型においては、第１図に
示される如く、ガス通路の外部に熱交換器を支持
する支持鉄骨が装備され、その水平力を支持する
装置となつている。 As conventionally known exhaust gas heat exchangers, there are many examples of a gas vertical flow type, and there are few examples of a gas horizontal flow type. In addition, as mentioned above, many of the heat exchangers are still under development and are relatively small.In this case, they are just equipped with heating pipes inside the gas duct, and the horizontal force caused by earthquakes etc. is also small, so it is difficult to develop full-scale heat exchangers. It is not designed to be earthquake resistant. In addition, in a relatively large-sized heat exchanger, as shown in FIG. 1, a support steel frame is installed outside the gas passage to support the heat exchanger, and serves as a device to support the horizontal force of the heat exchanger.
この場合、該鉄骨の中間部に熱交換器が装備さ
れているため、該鉄骨は該熱交換器用の排ガスダ
クトの外部だけでその水平力に耐える機構とする
必要があり、鉄骨部材が複雑かつ大きな部材とな
り、不経済な設計となつて省資源の面からも逆行
することになり好ましくない。さらには、熱交換
器外部に大きな鉄骨があるため、敷地面積として
も広い土地が必要になるなどの欠点を有してい
た。 In this case, since the heat exchanger is installed in the middle of the steel frame, the steel frame needs to have a mechanism that can withstand the horizontal force only on the outside of the exhaust gas duct for the heat exchanger, and the steel frame members are complicated and This is undesirable because it becomes a large member, resulting in an uneconomical design and going against the grain of resource conservation. Furthermore, since there is a large steel frame outside the heat exchanger, it has the disadvantage of requiring a large site area.

欠点を有していた。 As mentioned above, in the conventionally known means, a supporting steel frame is provided outside the circumferential wall of the gas passage of the heat exchanger to support the horizontal load of the heat exchanger, so the structure of the steel frame member is complicated and large members are required.

る。 In the present invention, the diagonal member device 42 for supporting the horizontal force in the width direction is installed in the exhaust gas passage, and the horizontal force in the gas flow direction is applied to the side exhaust gas passage peripheral wall 35-
By adopting a structure that supports in-plane rigidity of 2,
Without separately equipping a support steel frame, it is possible to completely safely support even a practically unlimited large heat exchanger, and to provide it at a low cost in a narrow site.

５−４に伝達される。 First, to explain the horizontal force in the gas flow direction, the horizontal force generated in the heating tube 9 passes through the header 10 at the bottom, via the support hardware 12 provided on the header 10, and is transferred to the lower support base. 15. Each of the lower support stands 15 is provided with a plurality of support legs 16, and the vertical force is supported by the support legs 16. Further, the horizontal force is transmitted via the horizontal force transmitting metal fitting 19 provided on the support base 15 to the horizontal force transmitting metal fitting 20 attached by welding to the exhaust gas passage peripheral wall 35-4 at the bottom.

になつている。 On the other hand, the upward horizontal force is transmitted to the support lugs 21 provided on the upper header 11, and the support lugs 21 are provided on each header 11 disposed in the gas flow direction. The support lugs 21 are connected by a connection ring 24 and are integrated. In this case, the displacement due to the difference in thermal expansion in the vertical direction of each header 11 can be freely avoided in practice because the connection system is a link and rotates, so that it does not cause strain. It's summery.

壁３５−１に伝達される。 Since it is integrated as described above, the horizontal force in the gas flow direction can be supported at one location. Therefore, the horizontal force is transmitted to the upper horizontal force transmission device 26 via the transmission hardware 25. The horizontal force transmitted to the transmission device 26 is transmitted via the transmission hardware 27 to the transmission hardware attached to the upper exhaust gas passage peripheral wall 35-1 by welding, and is transmitted to the exhaust gas passage peripheral wall 35-1. .

In the lower part, the air is transmitted to the lower support stand 15 via a support metal fitting 12 attached to the header 10 and a support metal fitting 13 . The horizontal force transmitted to the support base 15 is transferred to the transmission hardware 17 provided on the support base 15.

接一体化されている。 Since the exhaust gas passage peripheral walls 35-1 to 35-4 are formed of plate surfaces, their in-plane rigidity is extremely high, but their out-of-plane rigidity is small. Reinforcing hardware 36-1 to 36-4 for reinforcing the rigidity in the direction are integrally welded to the exhaust gas passage peripheral walls 35-1 to 35-4 at appropriate intervals.
