A combustion chamber 111 is formed above the boiler outer cylinder 110, and a burner 113 capable of burning fuel inside the combustion chamber 111 is provided inside the combustion chamber 111. On the lower side, a water tank 115 through which heating water, which is a heat exchange fluid, is collected and circulated. The inside of the water tank 115 is installed to penetrate the water tank 115 so as to heat the heating water circulated in the water tank 115 by using the combustion gas heated in the combustion chamber 111, and communicates with the combustion chamber 111. Associations 120 are provided. At this time, the association 120 is provided in communication with the combustion chamber 111, the outer surface is in contact with the heating water collected in the tank (115).
Accordingly, when combustion gas is generated in the combustion chamber 111 by the burner 113 of the combustion chamber 111, the heat of the heated combustion gas is moved into the associations 120, thereby increasing the temperature of the associations 120. The heat exchange is made to the process of raising to the heating water in the water tank 115. And the inlet and outlet (110a, 110b) for introducing and discharging the heating water into the water tank 115 in the boiler outer cylinder 110 to circulate while the heating water in the water tank 115 is constantly supplied into the water tank 115. Are installed respectively.
On the other hand, the lower portion of the boiler outer cylinder 110, there is a flow chamber 105 for communicating the flue 103 and the tube 120 to exhaust the combustion gas passed through the tube 120 through the flue (103) Formed. A noise container 107 is provided between the flue 103 and the flow chamber 105 to reduce the noise generated when the burner 113 is operated to the outside through the flue 103. That is, in the condensing boiler according to the present embodiment, the fuel is burned in the combustion chamber 111 by the burner 113, and the high-temperature combustion gas generated after the combustion is associated with the pipe 120, the flow chamber 105, and the noise chamber 53. ) And discharged to the outside while passing through the year (60) in turn.

One end of the fluid circulation pipe 133 is coupled to one of the water receiving plates 130 located at the top of the water tank 115 of the water receiving plates 130, and the other end thereof is the water tank of the water receiving plates 130. It is coupled to the other water hammer plate 130 located at the bottom in the (115). The diameter of the fluid circulation pipe 133 according to this embodiment is preferably 10mm.
On the other hand, the water hammer plate 130 according to the present embodiment is installed in a rectangular shape through the tube 120 is penetrated at regular intervals along the circumferential direction of the water hammer plate 130, in a row at the center of the water hammer plate 130 It is installed.

At this time, the heating water is supplied into the water tank 115 through the inlet 110a of the boiler outer cylinder 110, and the heating water circulates inside the water tank 115 to be in contact with the pipes 120 to exchange heat. The temperature rises. And the heating water whose temperature is raised is discharged to the outside of the water tank 115 through the outlet 110b of the boiler outer cylinder (110).
At this time, the heating water flowing into the water tank 115 through the inlet 110a is more turbulent in the process of circulating inside the water tank 115 by the water hammer plate 130 provided inside the water tank 115. Will occur. Then, the convection of the heating water is promoted so that heat exchange with the associations 120 occurs more quickly, thereby increasing the temperature of the heating water more quickly. That is, when the heating water passes between the water-receiving plates 130 and the water tank 115, more turbulence of the heating water is generated, and convection of the heating water becomes more effective, thereby increasing the heat exchange efficiency with the pipe 120. do.
