ことを特徴としている。 That is, the feed water preheating device of the present invention reduces the amount of heat held by the combustion gas by arranging a heat exchanger consisting of upper and lower headers and a large number of water pipes connecting them in the flow path of the combustion gas. In a configuration in which the water supply in the water pipe is preheated, in order to cause the combustion gas to flow from the bottom to the top,
A box-shaped chimney base having an inlet at the bottom and an outlet at the top is formed, and one entire side of the chimney base that does not have the inlet is opened, and the open side surface is made in this way. A side wall member is detachably attached to the side wall member, and the heat exchanger is housed inside the side wall member so as to face the inlet side and in an inclined manner along a diagonal line of the box-shaped chimney base. It is characterized by the fact that it has been installed.

る。 1 to 3 show an embodiment of a heat exchanger, and the heat exchanger 1 is constructed by connecting upper and lower headers 2 and 3 with a large number of water pipes 4. As shown in FIG. It is desirable that these water pipes 4 be constructed of finned pipes. A partition plate 5 is provided inside the upper header 2 to divide it into a water supply inlet chamber and a water supply outlet chamber. The sockets 6, 6 in both chambers form a water supply inlet and a water supply outlet. Note that it is also possible to provide a water supply inlet in the upper header 2 and a water supply outlet in the lower header 3 without providing the partition plate 5.

250℃、出口で約150℃程度になる。 FIG. 6 shows the state in which the heat exchanger 1 is arranged inside the chimney base 7, and the lower header 3 of the heat exchanger 1 is placed in the chimney base so that the entire surface faces the inlet 11. Placed on the bottom plate 10, the upper pipe header 2
is placed obliquely against the side wall member 8c of the chimney base where the inlet 13 is provided, and is arranged over almost the entire diagonal length of the chimney base. In the figure, reference numeral 14 indicates mounting holes for a water supply inlet pipe and a water supply outlet pipe provided in the side wall member of the chimney base corresponding to the position of the socket 6 of the heat exchanger 1. Note that it is desirable to provide a rectifying plate in the chimney base 7 so that the combustion gas flows uniformly. The inlet 11 is connected to the boiler side, and when the combustion gas that has flowed into the chimney stand 7 passes through the gaps between the water tubes of the heat exchanger 1, it exchanges heat with the water inside the water tubes.
It is discharged to the outside through a chimney connected to the On the other hand, the feed water heated by the combustion gas is sent to the boiler by a feed water pump, and the water temperature at the outlet of the heat exchanger 1 is usually about 60°C. In this case, the temperature of the combustion gas at the chimney stand 7 entrance is approximately
250℃, and at the exit it becomes about 150℃.

As explained above, this invention has a structure in which the heat exchanger is simply made into a cassette and pushed into the chimney base, so there is no need for a special mounting and fixing structure, and it is easy to assemble and replace. There is an effect. Moreover, since openings are provided on the entire side cross section when inserting and removing the heat exchanger, the operation is very easy and can be carried out in a short time.
