以下に押えられていた。 As a conventional example, a hot water type heater will be taken up and explained with reference to FIG. A burner 1 burns fuel such as gas or oil, and a heat exchanger 2 gives heat to circulating hot water. Some heat exchangers 2 include a primary heat exchanger and a condensing heat exchanger. Thereafter, the combustion gas is collected in the exhaust section 3 and exhausted to the outside by the exhaust fan 4. The circulating hot water is driven by a pump 5,
The hot water enters the equipment through the return pipe 6 and is sent out to the heating area through the outgoing hot water pipe 7. At this time, when the water is condensed in the heat exchanger 2, the condensed water is mixed with NOx, SOx, and CO2 in the exhaust gas and becomes PH=3 to 4, which significantly corrodes not only the heat exchanger but also the drainage ditch. Therefore, conventional heaters have an efficiency of 80% in the non-condensing range.

The feature of this neutralization device is that it has a containment tank in which a predetermined amount of condensed water remains, so even after combustion has stopped and HNO 3 in the condensed water has disappeared, that is, even after reactions 2 and 3 have been completed, the remaining condensed water remains. The reaction with water, that is, reaction formula 1, will continue, and when condensed water is poured again, even if there is a problem such as low temperature, reaction formula 1 has already been promoted, so neutralization will occur quickly. what is done,
Next, since the condensed water drips from directly above the block of neutralizer, the strongly acidic condensed water due to HNO 3 , the main component in the condensed water, is poured onto the upper surface of Mg, destroying the oxides and adhesion on the Mg surface. By removing the kimono and quickly carrying out Reaction Formula 2, it is possible to quickly carry out the reactions of Reaction Formulas 1 to 3 and complete the neutralization. Additionally, this neutralization device is designed to prevent clogging. If clogging occurs between the storage tanks 9 and 9', the condensed water is guided to the next storage tank 9'' through the bypass passage 5.The bypass passages 4 and 6 have the same effect. Each of the bypass passages communicates with each other, and also functions to release the hydrogen gas generated by Reaction Equations 1 and 2 to the upper part.Hydrogen gas is passed through the exhaust hole provided at the upper part of the bypass passage. 7 and 8 are discharged to the outside.

される。 Next, a case in which the present neutralization device is applied to a heating machine will be explained with reference to FIG. 2. 1 is a burner;
The primary heat exchanger 2 provides heat to the circulating hot water. After that, heat is given to the circulating hot water again in the condensing heat exchanger 3, and the condensed water generated in this heat exchanger is transferred to the condensed water collection port 5.
The condensed water is collected, neutralized by the above-mentioned neutralization device 6, and discharged to the outside through the condensed water discharge pipe 7. The combustion gas that has undergone heat exchange is collected in the exhaust section 4 and exhausted to the outside by the combustion fan 8. The circulating hot water is driven by a pump 9, enters the equipment through a hot water return pipe 11, and is led to a condensing heat exchanger 3. At this time, the hot water temperature is controlled to a temperature at which the combustion gas is sufficiently condensed. Thereafter, the circulating water passes through the pump 9 and the primary heat exchanger 2, and is sent out to the heating area from the hot water pipe 10.
