폐열을 이용한 보일러의 온수장치{hot-water equipment using waste heat of boiler}Hot-water equipment using waste heat of boiler

본 발명은 유류를 사용하는 보일러에서 배출되는 연소 열 중 폐열을 이용하기 위한 보일러에 관한 것으로, 특히 유류가 연소하면서 배출되는 폐열을 최대한 이용할 수 있도록 하여 에너지 손실을 방지하고, 연료의 절감 효과를 상대적으로 높히기 위한 폐열을 이용하는 보일러의 온수장치에 관한 것이다.The present invention relates to a boiler for using waste heat of the combustion heat discharged from the boiler using oil, in particular, to make the most of the waste heat discharged while burning the oil to prevent energy loss, and to reduce the fuel saving effect It relates to a water heater of a boiler using waste heat to increase the furnace.

종래의 연료를 사용하는 연소 기기 중 보일러의 경우에는 연료가 연소하는 과정에서 발생하는 열을 이용하고 남은 열은 연료를 연소시키기 위하여 공급되는 공기와 함께 폐열을 포함한 공기가 연도를 통해 대기중으로 배출되었기 때문에 대기 오염을 일으키는 원인이 되었고, 또한 높은 온도의 폐열을 대기 중에 방출시키므로 인해서 에너지 활용 면에서 상당한 손실을 초래하였던 것이다.In the case of a boiler using conventional fuel, in the case of a boiler, the heat generated during the combustion of fuel is used, and the remaining heat is discharged into the atmosphere through the flue along with the air supplied to burn the fuel. This caused air pollution, and also caused a considerable loss in energy utilization by releasing high-temperature waste heat into the atmosphere.

이러한 문제들을 해결하기 위하여 연도의 주면에 물탱크를 설치하고 그 내부에 연도를 지나게 하며, 연도의 표면에 방열판을 설치한 것이 개발되었으나 종래의 장치는 열효율이 낮을 뿐 아니라 연도의 내부는 온도가 높고, 연도의 외부는 물이 감싸고 있으므로 온도가 낮아 연도의 내외부의 온도차에 의해 결로현상이 발생하여 연도늬 내부에 이슬이 맺히게 되는데 이러한 이슬을 제거하지 못하므로 연도를 타고 보일러의 내부로 흘러들어가 연료가 연소하는데 지장을 초래하는 등의 문제점이 있었다.In order to solve these problems, water tanks are installed on the main surface of the flue, and the heat sink is installed inside the flue, and heat sinks are installed on the surface of the flue. However, the conventional apparatus has a low thermal efficiency and a high temperature inside the flue. However, since the outside of the flue is surrounded by water, condensation occurs due to the temperature difference between the inside and the outside of the flue, resulting in dew condensation inside the flue. There was a problem such as causing trouble in combustion.

본 발명은 상기와 같은 문제점을 해소하기 위하여 안출한 것으로 연료가 연소하는 과정에서 발생하는 폐열을 효율적으로 이용하고자 한 것으로서 연도에 열교환기가 내장된 온수저장 탱크를 설치하여 연도를 통해 배출되는 폐열에 의해 저장 탱크 내의 물을 가열함으로써 폐열을 재활용함을 목적으로 한다.The present invention has been made in order to solve the problems described above to efficiently use the waste heat generated during the combustion of the fuel by installing a hot water storage tank with a heat exchanger in the year by the waste heat discharged through the flue The purpose is to recycle waste heat by heating the water in the storage tank.

본 발명의 또 다른 목적은 연도의 내외부의 온도차에 의해 결로현상이 발생하여 연도에 이슬이 맺히더라도 내부의 수분을 배출하기 위한 장치를 구비하여 연도를 보호할 수 있도록 함에 있다. Still another object of the present invention is to provide protection for the flue by providing a device for discharging the moisture even if dew occurs in the flue due to the temperature difference between the inside and the outside of the flue.

상기 목적을 달성하기 위한 본 발명은 연료를 연소하여 물을 가열하는 보일러에 있어서 보일러의 연통을 감싸는 물 저장탱크와; 상기 물 저장탱크의 내부에서 연통의 외부에 방사상으로 다수의 파이프가 연통의 상하를 연결하는 상태로 연결되며, 상기 연통의 내부에는 이슬받이와 상기 이슬받이에 고인 물을 외부로 배출하기 위한 배출관으로 구비됨을 특징으로 한다.The present invention for achieving the above object is a water storage tank for enclosing the communication of the boiler in the boiler for heating the water by burning fuel; A plurality of pipes are connected radially to the outside of the communication in the water storage tank in a state connecting the top and bottom of the communication, the inside of the communication as a discharge pipe for discharging the water accumulated in the dew tray and the outside to the outside Characterized in that it is provided.

본 발명에 의하면 연료가 연소하는 과정에서 발생하는 폐열을 이용하여 연도에 열교환기가 내장된 온수저장 탱크를 설치하여 연통을 통해 배출되는 폐열에 의 해 물 저장탱크 내의 물을 가열함으로써 폐열을 재활용할 수 있어 열효율을 높일 수 있게 되는 것이며, 연도의 내외부의 온도차에 의해 결로현상이 발생하여 연도에 이슬이 맺히더라도 내부의 수분을 배출하기 위한 장치에 의해 외부로 배출되므로 연통을 보호할 수 있게 되는 것이다. According to the present invention, waste heat can be recycled by heating the water in the water storage tank by the waste heat discharged through the communication by installing a hot water storage tank having a heat exchanger in the flue using waste heat generated during the combustion of fuel. Therefore, it is possible to increase the thermal efficiency, even if dew condensation occurs due to the temperature difference between the inside and outside of the year, even if dew is formed in the year is discharged to the outside by the device for discharging the internal moisture to protect the communication.

이하 본 발명의 실시 예를 첨부된 도면을 참조하여 상세히 설명하면 하기와 같다. 우선 도 1을 참조하여 본 발명의 구성을 설명하면 연료를 연소하여 물을 가열하는 보일러(100)에 있어서 보일러의 폐열을 방출하는 연통(10)의 상부에 차단막(12)을 설치하여 폐열이 바로 빠져나가는 것을 방지하고, 상기 차단막으로부터 하측으로 소정의 거리만큼 떨어진 부위에 연통의 내주면에 이슬받이(15)를 설치하고 상기 이술받이(15)의 일측에 물을 배출하기 위한 배출관(17)을 설치되며, 연통(10)의 외면에는 연통을 감싸는 물 저장탱크(20)와 상기 물 저장탱크(20)의 외주 면을 감싸는 보온재(27)와 상기 보온재를 보호하기 위한 외부 케이스(28)를 설치한다. 이때 차단막(12)이 연통을 완전히 막을 경우 보일러의 연소에 문제가 발생할 수 있으므로 중앙에 작은 구멍(14)을 형성한다. 상기 물 저장탱크(20)의 내부에서 연통의 외부에 방사상으로 다수의 파이프(22)가 연통의 상하를 연결하는 상태로 연결하여 폐열과 연기를 외부로 내보낼 수 있도록 하기 위하여 상기 파이프(22)의 상단은 연통(10)의 내부에 설치된 차단막(12)보다 상부에 위치하도록 하며, 파이프의 하부는 이슬받이(15)의 상부에 위치하도록 한다. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, the configuration of the present invention will be described with reference to FIG. 1. In the boiler 100 that burns fuel and heats water, the waste heat is immediately provided by installing a barrier film 12 on the top of the communication 10 that emits the waste heat of the boiler. Prevents the escape, installs dew outlets 15 on the inner circumferential surface of the communication in a portion separated by a predetermined distance downward from the blocking film and a discharge pipe 17 for discharging water on one side of the tumbler 15. On the outer surface of the communication 10, a water storage tank 20 surrounding the communication and a heat insulating material 27 surrounding the outer circumferential surface of the water storage tank 20 and an outer case 28 for protecting the heat insulating material are installed. . At this time, when the blocking film 12 completely prevents communication, a problem may occur in the combustion of the boiler, so that a small hole 14 is formed in the center. Inside the water storage tank 20 of the pipe 22 in order to connect the plurality of pipes (22) radially to the outside of the communication in the state connecting the top and bottom of the communication so that the waste heat and smoke to the outside The upper end is positioned above the blocking film 12 installed in the communication 10, and the lower part of the pipe is positioned above the dew receiver 15.

또한 상기 물 저장탱크(20)의 일측 하부에는 물을 공급하기 위한 급수관(24)을 설치하고 상부에는 데워진 물을 배출하기 위한 배수관(26)이 설치되며, 상기 배수관(26)은 보일러(100)의 물을 공급하는 관에 연결한다. In addition, a water supply pipe 24 for supplying water is installed at one lower portion of the water storage tank 20, and a drain pipe 26 for discharging warmed water is installed at an upper portion thereof, and the drain pipe 26 is a boiler 100. To the water supply pipe.

위와 같이 구성된 본 발명의 작동과정을 설명하면 보일러(100)에서 연료를 연소하여 내부의 물을 가열한 후 화염과 연기를 외부로 방출하게 되는데 이를 안내하기 위한 연통이 설치되어 있으므로 상기 연통을 통해 폐열이 같이 빠져나가게 되므로 이를 효율적으로 이용하기 위하여 연통의 내부에 차단막(12)을 설치하였다.Referring to the operating process of the present invention configured as described above is to burn the fuel in the boiler 100 to heat the water inside and then release the flame and smoke to the outside, because the communication is installed to guide this waste heat through the communication In order to use it efficiently, the barrier layer 12 was installed inside the communication in order to use it efficiently.

따라서 연통의 하부로부터 올라오는 폐열은 차단막(12)에 막혀 위로 상승하지 못하고, 연통에 머무르게 되는 것이며, 연통의 외면의 물 저장탱크(20)에 저장된 물과 접촉하면서 열교환이 일어나 연통의 열이 물 저장탱크의 물을 데워주게 되는 것이며, 또한 연통을 통해 올라오는 연기와 화염을 배출하여야 하므로 연통에 설치된 차단막의 상·하부를 연결하는 파이프(22)가 설치되어 있으며, 상기 파이프(22)의 하부입구(22a)를 통해 차단막보다 상부로 연결된 출구(22b)를 통해 연통(10)의 상부로 빠져나가게 된다. 이러한 과정에서 파이프(22)가 물 저장탱크(20)에 가득 찬 물과 접촉하면서 열교환이 일어나 파이프의 열이 물 저장탱크의 물을 데워주게 되는 것이며, 열교환이 많이 일어나도록 하기 위하여 파이프(22)는 열 전도성이 좋은 알루미늄(Al) 또는 구리(Cu)로 된 재질을 사용하며, 물과의 접촉 면적을 넓히고자 파이프(22)는 방사상으로 다수 개 설치하였으며, 상·하부로 길게 형성하였다. Therefore, the waste heat rising from the lower portion of the communication is blocked by the blocking film 12 and does not rise upward, and stays in the communication. The heat of the communication is generated by contacting water stored in the water storage tank 20 on the outer surface of the communication. Since the water in the storage tank is to be heated, and smoke and flames coming up through the communication must be discharged, a pipe 22 connecting the upper and lower portions of the barrier film installed in the communication is installed, and the lower part of the pipe 22 The outlet 22b is connected to the upper portion of the communication 10 through the outlet 22b connected to the upper portion of the barrier film through the inlet 22a. In this process, the pipe 22 is in contact with the water filled in the water storage tank 20, the heat exchange occurs so that the heat of the pipe heats the water of the water storage tank, the pipe 22 to make a lot of heat exchange occurs The material is made of aluminum (Al) or copper (Cu) having good thermal conductivity, and a plurality of pipes 22 are radially installed to extend the contact area with water, and are formed long at the top and the bottom.

위와 같이 데워진 물은 보일러로 공급되므로 보일러에 공급되는 물은 이미 상기 물 저장탱크에서 데워진 상태로 급수되므로 물을 데우는데 보다 효율적으로 빠른 시간에 물을 데울 수 있게 되는 것이며, 데워진 물은 외부의 보온재(27)에 의해 외부와 차단되므로 열교환이 이루어지지 않으므로 보온된다. Since the heated water is supplied to the boiler, the water supplied to the boiler is already heated in the water storage tank, so that the water can be heated more quickly and more efficiently to heat the water, and the warmed water is an external thermal insulation material. Since it is blocked by the outside (27), heat exchange is not made, so it is kept warm.

이러한 과정에서 물 저장탱크(20) 내부의 물의 온도와 연통 내부의 온도차에 의해 연통의 내부에 이슬이 맺히게 되는데 이때 발생하는 이슬은 연통의 내면으로 흘러 연통의 중간에 설치된 이슬받이(15)에 고이게 되며, 이슬받이에 고인 물은 배출관 (17)을 통해 외부로 배출된다. In this process, dew forms in the interior of the communication by the temperature difference between the temperature of the water in the water storage tank 20 and the inside of the communication. The water accumulated in the dew receiver is discharged to the outside through the discharge pipe 17.

상기 과정에서 물 저장탱크의 데워진 물은 배수관(26)을 통해 보일러로 공급되는 것이며, 물이 보일러로 공급됨에 따라 물 저장탱크 내의 수위가 낮아지면 급수관(24)을 통해 외부에서 물을 공급하여 물 저장탱크(20) 내의 물이 일정 수위를 유지할 수 있도록 하는데 위와 같이 수위를 감지하여 물을 공급하는 수단은 다양한 방법에 의해 실시되고 있는 주지의 사실이므로 상세한 설명은 생략한다. In the above process, the warmed water of the water storage tank is supplied to the boiler through the drain pipe 26, and when the water level in the water storage tank decreases as the water is supplied to the boiler, water is supplied from the outside through the water supply pipe 24. Since the water in the storage tank 20 can maintain a constant level, the means for supplying water by sensing the water level as described above is well known because it is carried out by various methods, and a detailed description thereof will be omitted.
