In general, a heat recovery type boiler refers to a boiler designed to facilitate condensation heat exchange by installing a burner on the top or side of a heat exchanger to make the combustion gas flow downward and to lower the dew point temperature.

Unlike the Bunsen type boiler, this heat-absorbing boiler adopts a porous premixing method and installs a heat exchanger immediately after the flame surface to suppress the generation of nitrogen compounds and emit less carbon monoxide. Since it absorbs sensible heat first and latent heat discharged to exhaust gas secondly, the temperature of exhaust gas of general boiler is 150-260 ℃, whereas heat absorption boiler recovers heat by 50-120 ℃. High heat of more than% can be obtained.

And, in such a heat absorption boiler, water vapor contained in exhaust gas condenses below the dew point temperature and is discharged to the outside of the heat exchanger. Since the acidity of the condensate is about pH2.8-pH3.5, the acid condensate If it comes in contact with the components constituting the component, there is a risk of corrosion, and if such acid condensate is discharged to the sewer as it may cause environmental pollution.

The ceramic tube 40 is manufactured by firing at a predetermined temperature using a material having a basic so as to be neutralized when contacted with the condensate.

The through hole 42 of the ceramic tube 40 is neutralized while discharging the condensed water through the through hole 42 when the condensed water that is contacted with the neutralizing member 50 to be described later is not discharged due to an external situation. It is formed to be.

Therefore, the through hole 42 of the ceramic tube 40 may also be used by setting the diameter and number of the through holes 42 according to the characteristics and the capacity of the product, and such modified molding is also included in the configuration of the present invention. .

In addition, the length of the ceramic tube 40 is formed to be somewhat smaller than the length of the accommodating portion 31 of the neutralization case 30, so that the ceramic cover member 60 to be described later to be positioned above.

That is, the ceramic cover member 60, which is built into the through hole 41 of the ceramic tube 40 and installed above the neutralizing member 50, neutralizes the condensed water to flow into the neutralizing member 50. At the same time, since the member 50 prevents the outside of the through-hole 41 of the ceramic tube 40, the length of the ceramic tube 40 is greater than the length of the accommodating part 31 of the neutralization case 30. It is to form small.
