The gaseous heat medium supplied to the condenser 3 condenses and releases the heat of condensation to the outside of the system, and the released heat of condensation is used for heating.

る。 The basic structure of the present invention is as described in the claims for the utility model registration, and a heat exchange section is provided in the middle of the liquid pipe, and the heat exchange section is inserted into the combustion exhaust gas passage connected to the generator. As a result, the heat exchanger removes the thermal energy of the combustion exhaust gas and the heat of condensation of moisture contained in the combustion exhaust gas to preheat the liquid heat medium in the liquid pipe. Since the heat exchange section is located in the combustion exhaust gas passage away from the generator main body, it does not receive direct radiant heat from the burner and can appropriately heat the liquid heat medium in the liquid pipe without evaporating it. The condensate generated here does not fall into the generator, but is discharged to the outside along the combustion exhaust gas passage.

る。 According to this embodiment, the combustion exhaust gas is heat exchanged in the heat exchange section 19, and the liquid reservoir pipe 17 is heated by using the heat energy and the condensation heat contained in the moisture.
The heating efficiency is high because the liquid phase heating medium stored in the heating medium can be preheated. Moreover, liquid pipe 5
A liquid reservoir pipe 17, which is provided in the middle and has a pipe diameter larger than that of the liquid pipe 5, is inserted into the combustion exhaust gas passage 16, and a large amount of the liquid heat medium flowing from the condenser 3 is stored in the liquid reservoir pipe 17. This prevents the temperature of the liquid heat transfer medium from increasing significantly when the liquid storage pipe is heated by combustion exhaust gas, and as a result, evaporation of the liquid heat transfer medium within the liquid storage pipe is prevented. It is possible to appropriately raise the liquid temperature while preventing this. Further, a liquid reservoir pipe 17 equipped with a plurality of fins 18 and having a diameter larger than that of the liquid pipe 5 is inserted into the combustion exhaust gas passage 16, and the liquid reservoir pipe 17 is used as a heat exchange section with the combustion exhaust gas. Therefore, the configuration of the heating device can be simplified and made more compact. Further, since the drain generated in the heat exchange section 19 can be discharged to the outside from the vertical section 16b without entering the generator main body 11, there is no problem of the flame of the burner 1 being extinguished, and drain processing is easy. Furthermore, since the liquid reservoir pipe 17 of the heat exchange section 19 maintains a constant liquid level in the generator 2, it is possible to prevent dry heating due to load fluctuations and intrusion of liquid phase heat medium into the steam pipe 4. Smooth circulation of the heat medium can be promoted, and backflow of the heat medium can be prevented.

ることができる。 Since the present invention is configured as described above, combustion exhaust gas can be used effectively while solving problems such as drain treatment. Large amounts of thermal energy can be extracted from the condenser by increasing the temperature of the liquid phase heat transfer medium with exhaust gas.
Heating efficiency can be further improved. Moreover, since a large amount of the liquid heat medium flowing from the condenser is stored in the liquid reservoir pipe, which has a larger pipe diameter than the liquid pipe, the temperature of the liquid heat medium in the liquid reservoir pipe will rise significantly. As a result, the liquid temperature can be appropriately increased while preventing the liquid heat medium from evaporating within the liquid reservoir pipe. Furthermore, the liquid reservoir pipe equipped with a plurality of fins is inserted into the combustion exhaust gas passage, and the liquid reservoir pipe is used as a heat exchange section with the combustion exhaust gas, which simplifies the configuration of the heating device. , it is possible to achieve compactness.
