본 고안은 소형 보일러의 배출 연통에 장착하여 연소 배기가스의 폐열을 온수로 사용할 수 있도록 하는 연소 폐열 회수 장치에 관한 것이다.The present invention relates to a combustion waste heat recovery apparatus that can be installed in the exhaust communication of the small boiler to use the waste heat of the combustion exhaust gas as hot water.
종래, 소형 보일러에 있어서는 버너의 송풍기가 용량이 적고 버너의 형식도 건타입(GUN TYPE)이어서 배기 가스를 이용한 폐열 회수장치를 설치할 수 없고, 따라서, 배기가스로 방출되는 열량에 의한 열 손실이 크며, 손실되는 열량만큼 보일러의 열효율이 저하되는 결함이 지적되고 있다.Conventionally, in a small boiler, a blower blower has a small capacity and a burner type is a gun type, so that a waste heat recovery device using exhaust gas cannot be installed, and therefore, a large heat loss due to the amount of heat emitted into the exhaust gas is large. In addition, a defect is pointed out in which the thermal efficiency of the boiler is reduced by the amount of heat lost.
본 고안은 상기와 같은 결함을 해소하기 위하여 온수보일러의 배기가스 연통에 온수교환기를 내장시킨 열교환 장착기를 설치하여 온수열교환기의 내부온수가 일정 온도에 상승되었을 때 온수가 배출되고, 배기가스가 일정온도에 상승되었을 때 열교환이 이루워지도록 한 것으로, 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention provides a heat exchanger equipped with a hot water exchanger in the exhaust gas communication of the hot water boiler in order to solve the above defects, the hot water is discharged when the internal hot water of the hot water heat exchanger rises to a certain temperature, the exhaust gas is constant The heat exchange is achieved when the temperature is elevated, and will be described in detail with reference to the accompanying drawings.
즉, 온수보일러(1)의 배기가스 연통(1′)상부에 후렌지(3)로 열교환장착기(A)의 배기가스입구(4)를 접속하고, 열교환장착기(A)의 장착요입부(5)에 온수열교환기(B)를 착탈 자재토록 하되, 온수열교환기(B)의 후레임(6)내에 설치한 온수순환 동관(7′)에 동핀(7″)을 용착시킨 열교환튜브(7)를 장착하고, 열교환핀튜브(7) 일단에 전동펌프(8)와 전동삼방변(9)을 부착한 다음, 전동펌프(8)일측에 연결시킨 배기가스 온도감지봉(10)을 열교환장착기(A)일측상방의 브라켓트(11)에 끼우고, 열교환기(B)의 열교환핀튜브(7)타단의 온수 배출관측에 전동삼방변(9)과 연결된 온수온도 감지봉(12)를 설치하여 온수열교환기(B)의 내부 온수가 일정온도에 상승되었을 때 온수가 배출되고, 배기가스가 일정 온도에 상승되었을 때 열교환이 이루어지도록 하는 것이다.That is, the exhaust gas inlet 4 of the heat exchanger mounting unit A is connected to the exhaust gas communication 1 'of the hot water boiler 1 with a flange 3, and the mounting recess 5 of the heat exchanger mounting unit A is connected. The hot water heat exchanger (B) is attached to and detached from the heat exchanger, but the heat exchange tube (7) in which a copper fin (7 ″) is welded to the hot water circulation copper pipe (7 ') installed in the frame (6) of the hot water heat exchanger (B) is mounted. Then, the electric pump (8) and the electric triangular (9) is attached to one end of the heat exchange fin tube (7), the exhaust gas temperature sensing rod (10) connected to one side of the electric pump (8) heat exchanger (A) The hot water heat exchanger is installed by attaching the hot water temperature sensing rod 12 connected to the bracket 11 on one side and connected to the electric triangular valve 9 on the hot water discharge pipe side of the heat exchange fin tube 7 of the heat exchanger B. Hot water is discharged when the internal warm water in (B) is raised to a certain temperature, and heat exchange is performed when the exhaust gas is raised to a certain temperature.
상기에 있어서, 온수열교환기(B)의 후에임(6)내에 동핀(7″)을 용착시킨 온수순환동관(7′)을 사용하므로서 보일러(1)의 배기가스에 의한 금속의 팽창과 수축, 열응력과 열전도 및 그을음에 대한 금속의 내구력을 가질 수 있도록 한다.In the above description, expansion and contraction of the metal by the exhaust gas of the boiler 1 by using the hot water circulation copper tube 7 'in which the copper fin 7 ″ is welded in the lame 6 after the hot water heat exchanger B, It has the durability of the metal against thermal stress, heat conduction and soot.
그리고, 전동펌프(8), 전동삼방변(9), 압력상승 안전변(13)등은 후레임(6)일측에 부착된 지지판(14)상방에 위치토록하되, 조절기 박스(15)로 카버하고, 조절기 박스(15)일측에 부착된 분전함(16)내에 배기가스 온도감지기(17)와 온수온도감지기(18)를 내설시키고 있다.Then, the electric pump (8), electric triangular valve (9), pressure rising safety valve (13) and the like to be located above the support plate (14) attached to one side of the frame (6), cover with a regulator box (15), The exhaust gas temperature sensor 17 and the hot water temperature sensor 18 are housed in the distribution box 16 attached to one side of the regulator box 15.
도면중 19는 체결볼트, 20은 물입구측, 21은 온수출구, 22는 보온재, 23은 연소 배기가스 출구이다.19 is a fastening bolt, 20 is a water inlet side, 21 is a hot water outlet, 22 is a heat insulating material, 23 is a combustion exhaust gas outlet.
이상과 같이 구성된 본 고안의 작용효과는 다음과 같다.Effects of the present invention configured as described above are as follows.
물입구측(20)을 통해 온수열교환기(B)내부에 물이 인입되게 되는데, 보일러(1)가 작동되면 연소된 배기가스가 열교환장착기(A)의 배기가스입구(4)를 통해 상승되고, 온수열교환기(B)의 열교환핀튜브(7)에서 열이 흡수된후 상부의 연소배기가스출구(23)측으로 배출됨에 따라 보일러(1)의 폐열을 온수열교환기(B)로 회수하여 온수를 사용할 수 있게 되므로 열손실을 방지하고, 보일러(1)의 효율향상은 물론 에너지 절약이 되는 것이다.Water is introduced into the hot water heat exchanger B through the water inlet side 20. When the boiler 1 is operated, the burned exhaust gas is raised through the exhaust gas inlet 4 of the heat exchanger mounting unit A. After the heat is absorbed from the heat exchange fin tube 7 of the hot water heat exchanger B and discharged to the combustion exhaust gas outlet 23 on the upper side, the waste heat of the boiler 1 is recovered by the hot water heat exchanger B to obtain hot water. Since it can be used to prevent heat loss, the efficiency of the boiler (1) is of course to save energy.
만일, 열교환핀튜브(7)가 그을릴 경우에 점검을 하기 위하여 체결볼트(19)를 나해하여 열교환장착기(A)의 장착요입부(5)로부터 열교환기(B)를 탈리시키면 된다.If the heat exchange fin tube 7 burns, the heat exchanger B may be detached from the mounting concave portion 5 of the heat exchanger mounting unit A through the fastening bolt 19 for inspection.
이때, 보일러(1)작동중 배기가스가 135℃ 이상이 되면 배기가스온도 감지봉(9)이 이를 감지하여 배기가스 온도감지기(17)가 작동하게 되어 전동펌프(8)를 작동시키게 되므로 물을 열교환 핀튜브(7)내부로 순환시키게 된다.At this time, when the exhaust gas is more than 135 ℃ during the operation of the boiler (1) is detected by the exhaust gas temperature sensing rod (9) to operate the exhaust gas temperature sensor (17) to operate the electric pump (8) because water It is circulated inside the heat exchange fin tube (7).
그런데, 상기에 있어서, 제4도의 전기 배선도에서 보면, 전동 삼방면(9)이 온수 온도감지기(18)의 미작동에 따라 삼방변(9)의 물입구측(20)이 닫혀져 있게 된다.By the way, in the above, as shown in the electrical wiring diagram of FIG. 4, the water inlet side 20 of the three sides 9 is closed by the electric three sides 9 by the non-operation of the warm water temperature sensor 18. As shown in FIG.
이와같이 열교환핀튜브(7)내부의 물은 전동펌프(8)에 의해 일정온도가 상승될때까지 계속 순환하게 되고, 열교환핀튜브(7)내부의 물의 온도가 65℃ 이상되면, 온수온도 감지봉(12)이 이를 감지하여 온수온도 감지기(18)가 작동하게 되어 전동삼방변(9)을 작동시키게 되므로 삼방변(9)의 물입구측을 개방하게 된다.As such, the water in the heat exchange fin tube 7 continues to circulate until a constant temperature is increased by the electric pump 8, and when the temperature of the water in the heat exchange fin tube 7 is 65 ° C. or higher, a hot water temperature sensing rod ( 12) detects this, the hot water temperature sensor 18 is operated to operate the electric three-way (9) to open the water inlet side of the three-way (9).
따라서, 온수출구(21)측으로 온수가 배출되게 되는 것이다.Therefore, hot water is discharged to the hot water outlet 21 side.
만일, 보일러(1)의 작동이 중지되면 연소가스가 냉각되고 온수 열교환기(B)의 내부 온수온도가 65℃이하가 되면 온수온도 감지기(18)이 작동에 따라 전동삼방변(9)의 물입구측을 닫게 하므로 물공급이 중단하게 된다.If the operation of the boiler 1 is stopped, the combustion gas is cooled, and if the internal hot water temperature of the hot water heat exchanger B is 65 ° C. or lower, the hot water temperature sensor 18 operates in accordance with the operation of the water in the electric triangular toilet 9. The inlet side is closed, so the water supply is interrupted.
물론, 보일러(1)배기가스의 온도가 135℃ 이하가 되면 배기 가스온도감지기(17)가 작동하여 전동펌프(8)의 작동을 정지시키게 된다.Of course, when the temperature of the exhaust gas of the boiler 1 is 135 ° C. or less, the exhaust gas temperature sensor 17 is operated to stop the operation of the electric pump 8.
한편, 제6도는 본 고안의 설치 상태도로서 폐열을 온수로 회수하여 필요한 곳에 온수를 공급할 수 있는 것을 보인 것이며, 제7도는 온수 보일러에 급탕용 코일이 내장되어 있을 경우에 폐열을 온수로 회수하여 급수의 예열로 사용한 예이다.On the other hand, Figure 6 is an installation state diagram of the present invention shows that the waste heat can be recovered as hot water to supply hot water where necessary, Figure 7 shows that the waste heat is recovered as hot water when the hot water coil is built in the hot water boiler This is an example used for preheating.
제8도는 온수보일러와 급탕용 저탕조가 있을 경우에 폐열을 온수로 회수하여 저탕조에 축열로 사용한 예이다.8 is an example in which waste heat is recovered as hot water when the hot water boiler and the hot water storage tank are used as heat storage in the water storage tank.
이상과 같이 본 고안은 열교환 장착기에 열교환핀튜브, 전동펌프, 전동삼방변등을 유니트화한 온수열교환기를 착탈 자재토록 하고, 보일러의 배기가스의 열을 온수열교환기로 회수하여 에너지를 절약하며, 온수열교환기의 내부온수가 일정온도에 상승되었을때 온수가 배출되도록 하고, 배기가스가 일정온도에 상승되었을때 열교환이 이루어지도록 하는 유용하고도 실용적인 고안이다.As described above, the present invention allows the hot water heat exchanger in which the heat exchanger fin tube, the electric pump, and the electric three-way valve are united to be removed from the heat exchanger. It is a useful and practical design to allow hot water to be discharged when the internal warm water of the heat exchanger is raised to a certain temperature, and to perform heat exchange when the exhaust gas is raised to a certain temperature.
