At the positions of holes 24 and 25 of holes 2 and 23, flanged holes 28 and 29 are provided, respectively. These flanged holes 28 and 29 are formed to have a slightly smaller diameter than the outer diameter of the borosilicate glass tube 21. Furthermore, small-area Teflon molded products 30 and 31 are provided outside the holes 24 and 25 of the side plates by fixing means such as headed screws. These small-area molded products 30 and 31 are both provided with flanged holes 32 and 33 in their central portions. These flanged holes 32, 33
is formed to have a slightly smaller diameter than the outer diameter of the borosilicate glass tube 21. Each borosilicate glass tube 21 is airtightly supported by the side plate by inserting its both sides into the holes 32, 28 and 29, 33 so as to extend the tubes. The ends of each borosilicate glass tube are hermetically connected to each other on the outside of both side plates 22, 23 by a conventionally known U-shaped tube 34. One pipe end that is not connected by the U-shaped pipe is connected to a water supply pipe 35, and a foot valve 37 is attached to the pipe end of the water supply pipe 35 in a water supply tank 36.
The other pipe end that is not connected by the U-shaped pipe is connected to the discharge pipe 38 of the low temperature economizer, and the drain pipe 3
8 is connected to the suction side of the water supply pump 39. A delivery pipe 40 of the water supply pump 39 is connected to a water supply pipe to a high-temperature economizer made of cast iron (not shown). The outer periphery of this low-temperature economizer is surrounded by a heat insulating material 41 and housed in a container 42 to form a unit type. Therefore, the combustion gas flows along the outside of the tubes in the space where a number of borosilicate glass tubes are arranged horizontally between the side plates of this low-temperature economizer, as shown by the arrows. Water is sucked up from the water supply tank 35 by the water supply pump 39, and flows smoothly at a fairly high speed through the borosilicate glass tube 21 of the low temperature economizer connected by a U-shaped pipe, until it reaches the stagnation part. Do not cause Even when the temperature of the combustion exhaust gas becomes low, close to the dew point, this low-temperature economizer can prevent corrosion at the parts that come into contact with the exhaust gas, thereby extending its service life.
