＜なり、かつ降水管を下降した内部を生じている。In the boiler with the above configuration, each evaporator has a large number of headers, and the arrangement of the water supply pipes that supply water to the header is complicated. Figure 2 shows an example of how water supply pipes are branched. In the figure, a small header ladder 12 is attached to the lower end of a downcomer pipe (the one shown is a high-pressure downcomer pipe 8), and a large number of water supply pipes 14 are connected to this header. The artificial header (lower header) of each heat exchanger tube panel is connected to the downcomer pipe 8. Here, the entire boiler is constructed by consecutively arranging blocks constructed for each group of heat exchanger tubes,
For example, the header 12 attached to the downcomer pipe 8 must be placed in a space with a width between the installation part of the downcomer pipe 8 and the end face of the evaporator block, as shown in FIG.
However, the connection of each water supply pipe 14 becomes complicated as shown in the figure. Therefore, the arrangement of each water supply pipe is ff([L

に比較して強度も高くなる。Figure 3 shows the water circulation system on the high pressure side. Two downcomer pipes 8a, 8b are connected to the high-pressure drum 9, and an intermediate header 15 is attached to the lower end of each downcomer pipe 8a, 8b. This intermediate header 15 is arranged so as to be substantially parallel to the drum 9, and its total length is approximately equal to the total length of the drum 9, making it large. 16 is a lower header (inlet header) of each heat exchanger tube panel, and the water supply pipe 14 connects each of these headers 16 and the intermediate header 15. In this case, since the intermediate header 15 is large, the water supply shield 14
can be freely connected to the side of the ladder 15 to this middle part, making it very easy to arrange the water supply pipe 14. Furthermore, since the two downcomer pipes 8a, 8b, the drum 9, and the intermediate ladder 15 form a substantially rectangular frame structure, the strength is higher than that of the piping structure shown in FIG.
第４図は供水管１４の配置状態の一例を示す。FIG. 4 shows an example of the arrangement of the water supply pipes 14.

が、低圧側も同様の構造とする。Normally, the lower header 16 of each heat exchanger tube panel is cut in its length direction and divided into multiple chambers or into multiple pipes, so the number of divided water pipes required for one lower header is Become. Therefore, the number of water supply pipes will be considerably large, but
Since the intermediate header 15 is long, each water supply pipe 14 can be connected to the intermediate header 15 at approximately equal intervals, and the work of attaching the water supply pipes is easy. Although the above explanation has been given using the high pressure side piping as an example, the low pressure side has a similar structure.
この発明を実施することにより供水管の設置本数が多数
であっても各供水管の取り付けを容易に行うことができ
る。By implementing this invention, even if a large number of water supply pipes are installed, each water supply pipe can be easily installed.
また中間ヘッダを補強部材として利用することができる
ので装置全体の強度を高めることができる。Furthermore, since the intermediate header can be used as a reinforcing member, the strength of the entire device can be increased.
