이와 같이 1차, 2차로 구분된 열교관 파이프(7)(8)와 열교한 파이프(7)(8)의 내경과 외경에 의해서 형성되는 폐가스 이송통로(14)(15)를 가지는 본 발명의 작동을 설명하면 다음과 같다.Thus, the present invention has the waste gas transfer passages 14 and 15 formed by the inner and outer diameters of the primary and secondary heat exchanger pipes 7 and 8 and the heat bridged pipes 7 and 8. The operation is described as follows.

보일러의 버너(4)를 가동하여 연소실(2)에 화력을 형성하고, 연소실(2)에 형성된 화력의 강약을 연소실(2)에 형성된 투시창(3)을 통하여, 사용자가 연소실(2)의 상태를 판단하면서, 연소실(2)의 화력을 조절할 수 있는 것이다.The burner 4 of the boiler is operated to form a thermal power in the combustion chamber 2, and the user is in a state of the combustion chamber 2 through the sight window 3 formed in the combustion chamber 2. While judging, it is possible to adjust the fire power of the combustion chamber (2).

상기와 같이 보일러 내부에 화력이 형성되어, 열기가 보일러 몸체(1)에 형성되면, 연소실(2)의 열기는 연소실(2) 일면으로 연통되어 형성된 1차 다수개의 열교환 파이프(7)를 통하여 열기가 이송하면서, 1차로 열교환 파이프(7)를 가열하면서 전면으로 이송되어, 폐가스 토출구(9)로 배출되어 보일러 몸체(1)를 따라 순환되는 것이다.상기와 같이 보일러 몸체(1)를 따라 순환된 열기는 폐가스 유도판(11)에 의해 열기가 2차 열교환 파이프(8)로 유입되며서, 1차 열교환 파이프(7) 내측으로 위치한 2차 열교환 파이프(8)를 가열하면서 전면으로 이동하는 것이다.상기와 같이 이동된 열기(폐가스)는 전면으로 위치한 폐가스 집수실(6)로 모이면서 폐가스 토출구(9)를 경유하여, 보일러 몸체(1)를 따라 이송하다가, 폐가스 최종배출구(19)로 배출되는 것이다.본 발명의 상기 작업에서 1차 열교환 파이프(7) 외측으로 2차 열교환 파이프(8)가 형성되므로, 2중으로 형성된 열교한 파이프(7)(8)의 내경과 외경이, 열교환 파이프(7)(8)를 가열하는 열기를 이송하는 2중 구조의 폐가스 이송통로(14)(15) 기능을 수행하므로, 1차 열교환 파이프(7)의 내경은 1차 폐가스 이송통로(14)가 되는 것이며, 2차 열교환 파이프(8)의 외경은 2차 폐가스 이송통로(15)가 되는 것이다.그러므로 연소실(2)에서 발생한 열기가 폐가스 이송통로(14)(15)로 순환되면서, 반복 이송되면서 열교환 파이프(7)(8)를 2중으로 가열하는 기능을 수행할 수 있는 것이다.상기와 같이 연소실(2)이 가열된 상태에서, 보일러의 용수 투입구(5)에 온수로 가열하고자하는 용수를 투입하면, 1차 열교환 파이프(7) 외측으로 형성되는 1차 온수 이송통로(13)로 유입되면서 1차 열교환 파이프(7)에 의해 1차로 가열되면서, 1차 온수 집수실(10)로 이송되는 것이다.본 발명은 상기와 같이 1차로 가열된 용수는 순환되어 1차 열교환 파이프(7)와 2차 열교한 파이프(8)의 이격공간으로 형성된 2차 온수 이송통로(20)로 유입되어 재차 가열되면서 이동되어, 2차 온수 집수실(16)에 모이는 것이다.상기와 같이 1차 온수 이송통로(13)과 2차 온수 이송통로(20)에 의해 가열되어 2차 온수 집수실(16)에 유입된 온수는 온수 배출구(12)를 통하여 보일러 몸체(1)에서 배출되어, 사용자가 난방수와 온수로 사용하는 것이다.When the thermal power is formed in the boiler as described above, and heat is formed in the boiler body 1, the heat of the combustion chamber 2 is heated through a plurality of primary heat exchange pipes 7 formed in communication with one surface of the combustion chamber 2. While conveying, it is first conveyed to the front while heating the heat exchange pipe (7), discharged to the waste gas outlet (9) and circulated along the boiler body (1). The heat is introduced into the secondary heat exchange pipe 8 by the waste gas guide plate 11 and moves to the front side while heating the secondary heat exchange pipe 8 located inside the primary heat exchange pipe 7. The hot air (waste gas) moved as described above is collected in the waste gas collecting chamber 6 located at the front side, and is transported along the boiler body 1 through the waste gas discharge port 9, and then discharged to the waste gas final discharge port 19. The above of the present invention Since the secondary heat exchange pipe 8 is formed outside the primary heat exchange pipe 7 in operation, the inner diameter and the outer diameter of the double heat bridged pipes 7 and 8 heat the heat exchange pipes 7 and 8. Since the waste gas transfer passage 14 (15) of the dual structure to transfer the heat to perform the function, the inner diameter of the primary heat exchange pipe 7 is to be the primary waste gas transfer passage 14, the secondary heat exchange pipe ( The outer diameter of 8) becomes the secondary waste gas conveying passage 15. Therefore, the heat generated in the combustion chamber 2 is circulated to the waste gas conveying passages 14 and 15, and is repeatedly conveyed while the heat exchange pipes 7 and 8 are transferred. It is possible to perform the function of heating the double. When the combustion chamber 2 is heated as described above, when the water to be heated with hot water to the water inlet 5 of the boiler, the primary heat exchange pipe (7) ) To the primary heat exchange pipe (7) while flowing into the primary hot water transport passage (13) formed to the outside By the primary heating, it is transferred to the primary hot water collection chamber (10). In the present invention, the primary heated water is circulated to the primary heat exchange pipe (7) and the secondary heat bridge (8) It is introduced into the secondary hot water transport passage 20 formed as a spaced apart space is moved while being heated again, gathered in the secondary hot water collection chamber 16. As described above, the primary hot water transport passage 13 and the secondary hot water transport passage. The hot water heated by 20 and introduced into the secondary hot water collection chamber 16 is discharged from the boiler body 1 through the hot water discharge port 12, and is used by the user as heating water and hot water.

상기에서 상세하게 설명한 바와 같이, 1차, 2차로 형성된 열교환 파이프(7)(8)에 의해서, 보일러 내부의 열기가 잔류하는 시간이 연장되면서, 보일러 내부에 유입된 용수가 열교환 파이프(7)(8) 안쪽과 바깥쪽면에 접하면서 2중으로 가열되므로, 보일러 내부에 용수가 신속하게 가열되는 효과가 있으며, 또한 폐가스의 이송이 1차, 2차로 구분된 폐가스 이송통로(14)(15)에 의해서, 보일러 내부에 잔류하는 시간을 연장되므로, 용수 가열을 위한 폐가스 사용량을 감소시키는 효과가 있는 것이다.As described in detail above, by the heat exchange pipes 7 and 8 formed primarily and secondly, while the heat remaining inside the boiler is extended, the water introduced into the boiler heat exchange pipe 7 ( 8) Since it is heated twice in contact with the inner and outer surfaces, the water is heated quickly inside the boiler, and also by the waste gas transfer passages 14 and 15 in which the waste gas is separated into primary and secondary. Since the time remaining inside the boiler is extended, there is an effect of reducing the amount of waste gas used for water heating.
