である。(Prior Art) Generally, as shown in FIGS. 1 and 2, this type of condenser has a can body C on both sides, which is provided with a steam supply port a and a condensate outlet b for condensed condensate. A pair of end plates d and e are provided in the section, and a large number of cooling tubes f made of thick-walled brass tubes are passed through the end plates d and e and fixed by expanding or welding. is supported by a plurality of support plates g, and on the other hand, it has a front bend member i having a cooling water supply port h on the outside of the above-mentioned both end plates d and e, and a heat exchanged cooling water discharge port j.

出口ｂから外方へ流出するようになつている。 Therefore, the above-mentioned condenser discharges cooling water from the supply port h of the front bend member i to the discharge port j of the rear bend member k through a large number of cooling pipes f made of thick-walled brass pipes. , on the other hand, the steam that has completed its work in the turbine is heat exchanged from the supply port a through the outside of a large number of cooling pipes f provided in the can body c,
Here, the steam is condensed to form condensate, which flows outward from the condensate outlet b.

水が漏洩して復水と混合したり、冷却管ｆの撓み
を生じる原因になつている。(Problem to be Solved by the Invention) However, the cooling pipe group in the above-mentioned condenser is affected by the condensation effect of steam, that is, as the flow rate of steam decreases and the dynamic pressure load decreases, due to this, , since each cooling pipe f is bent and obstructs the smooth flow of the cooling pipe, in order to eliminate this, each cooling pipe f is made of thick brass pipe, and furthermore,
Although this is supported by a support plate g, even with this, the inner circumferential surface of each cooling pipe f is corroded when operated for a long time due to impurities contained in the cooling water and excessively flowing cooling water. This causes cracks to occur, which causes cooling water to leak and mix with condensate, and to cause the cooling pipe f to bend.
このような冷却水による漏洩事故が発生する

ラントの発電効率を低下する原因になつている。 When such a leakage accident due to cooling water occurs, the operation of the entire power plant must be stopped or the output must be halved, causing a reduction in the power generation efficiency of the power plant.

るかにコスト高になる等の難点がある。 Therefore, in order to eliminate the above-mentioned cooling pipe leakage accident caused by thick brass pipes, it is possible to use corrosion-resistant cooling pipes such as titanium pipes. Similar to the brass tube mentioned above, if a titanium tube of the same shape and size is used, the heat conduction efficiency will be significantly lowered and the heat exchange efficiency will be reduced, and the cost will be much higher than that of a brass tube. There are other difficulties.

If this is installed as is in a conventional condenser, the cooling pipe, which is a thin titanium pipe, will bend and obstruct the smooth flow of cooling water, so there are drawbacks such as the need to incorporate a large number of support plates. .

(Means for Solving the Problems) The present invention provides a pair of end plates on both sides of a can body having a steam supply inlet and a condensate outlet, and a number of corrosion-resistant cooling pipes are installed between the two end plates. In the condenser installed through the condenser, each cooling pipe located on the outside of the cooling pipe group is supported by a plurality of arc-shaped support members, and each support member is placed in contact with each deflector plate. The cooling pipes are formed by dividing them so that they do not touch each other, and the outer periphery of each divided support member is fixed by each stay bolt passed through each stay pipe, thereby increasing the corrosion resistance of the cooling pipe. It is something.
