And a guide duct 6 formed to discharge the exhaust gas in the case 2.

상기 케이스(2)는 상기 연돌(120)에 통하도록 일측에 입구(22)가 형성되고 내부에 공간이 형성되며 타측에 출구(24)가 형성된다.The case 2 has an inlet 22 formed on one side and a space formed therein, and an outlet 24 formed on the other side so as to communicate with the stack 120.

상기 입구(22)에는 배기가스 중의 유해성분을 여과시킬 수 있도록 촉매로 구성된 필터(8)가 더 설치된다.The inlet 22 is further provided with a filter 8 composed of a catalyst so as to filter harmful components in the exhaust gas.

상기 저수챔버(4)는 상기 케이스(2)의 내부 공간에 형성되며 배기가스가 통과하는 다수의 열교환관(5)이 형성된 것으로, 일측에는 외부의 급수관(42)과 연결되고, 타측에는 외부의 온수공급관(44)과 연결된다.The water storage chamber 4 is formed in the inner space of the case 2 and formed with a plurality of heat exchange tubes 5 through which the exhaust gas passes, and is connected to an external water supply pipe 42 on one side and an external on the other side. It is connected to the hot water supply pipe (44).

상기 열교환관(5)은 방사상으로 다수로 설치된 파이프이며, 수직의 직선형 또는 코일형으로 형성된 것으로, 발열성능이 뛰어난 동 또는 알루미늄 재질이 바람직하나 반드시 이에 한정되지는 않는다.The heat exchange tube 5 is a radially installed pipe, which is formed in a vertical straight or coil form, preferably copper or aluminum having excellent heat generating performance, but is not necessarily limited thereto.

상기 가이드덕트(6)는 상기 열교환관(5)을 통과하여 배출되는 배기가스를 유도하여 상기 출구(24)로 안내하기 위해 상기 케이스(2)의 내부에 형성된 것으로, 상기 입구(22)에 연결되어 열교환관(5)의 상단에 연결되도록 형성된 유입통로(62)와, 상기 열교환관(5)의 하단에 연결되며 상기 출구(24)에 통하도록 형성된 유출통로(64)로 구성된다.The guide duct 6 is formed inside the case 2 to guide the exhaust gas discharged through the heat exchange tube 5 to the outlet 24, and is connected to the inlet 22. And an inflow passage 62 formed to be connected to the upper end of the heat exchange tube 5, and an outlet passage 64 connected to the lower end of the heat exchange tube 5 and connected to the outlet 24.

특히, 상기 유입통로(62)의 내측에는 배기가스가 와류를 형성하지 않고 자연스런 흐름상태로 열교환관(5)으로 유입될 수 있도록 굴곡부(623)가 형성된다.In particular, a bent portion 623 is formed inside the inflow passage 62 to allow the exhaust gas to flow into the heat exchange tube 5 in a natural flow state without forming a vortex.

이하 상기와 같이 구성된 본 발명의 작용을 설명한다.Hereinafter, the operation of the present invention configured as described above.

케이스(2)의 출구(24)를 보일러(100)의 연돌(120)에 연결하고, 저수챔버(4)의 내부로 급수관(42)을 통해 냉수를 공급하여 일정량의 물이 저수챔버(4) 내에 저수된 상태가 되도록 한다.The outlet 24 of the case 2 is connected to the stack 120 of the boiler 100, and the cold water is supplied into the water storage chamber 4 through the water supply pipe 42 so that a predetermined amount of water is stored in the water storage chamber 4. It is to be stored in a state.

이후 보일러(100)를 가동시키면 발생된 배기가스가 연돌(120)을 통해 가이드덕트(6)의 유입통로(62)를 경유하여 열교환관(5)으로 유입된다.Thereafter, when the boiler 100 is operated, the generated exhaust gas is introduced into the heat exchanger tube 5 through the inflow passage 62 of the guide duct 6 through the stack 120.

따라서, 배기가스가 열교환관(5)을 지나는 동안 저수된 물과 열교환을 통해 가열작용을 하게 되고, 차가워진 배기가스는 가이드덕트(6)의 유출통로(64)를 통과하여 케이스(2)의 출구(24)를 통해 외부로 배출된다.Accordingly, while the exhaust gas passes through the heat exchange tube 5, the exhaust gas is heated by heat exchange with the stored water, and the cooled exhaust gas passes through the outflow passage 64 of the guide duct 6 so that It is discharged to the outside through the outlet 24.

상기 저수챔버(4)의 가열된 물은 온수공급관(44)을 통해 보일러(100)에 재공급되거나 기타 온수용도로 사용될 수 있을 것이다.The heated water of the reservoir chamber 4 may be resupplied to the boiler 100 through the hot water supply pipe 44 or used for other hot water purposes.

비록 본 발명이 상기 언급된 바람직한 실시예와 관련하여 설명되어졌지만, 발명의 요지와 범위로부터 벗어남이 없이 다양한 수정 및 변형이 가능한 것은 당업자라면 용이하게 인식할 수 있을 것이며, 이러한 변경 및 수정은 모두 첨부된 청구의 범위에 속함은 자명하다.Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, It is obvious that the claims fall within the scope of the claims.
