본 고안은 난방 기능과 급탕기능을 동시에 갖춘 가정용 기름 보일러에 관한 것을, 특히 폐열의 효율적인 이용과 버어너의 하향 분사가 이루어지도록 된 에너지 절약형 보일러에 관한 것이다.The present invention relates to a domestic oil boiler having a heating function and a hot water supply function, and more particularly, to an energy-saving boiler that allows efficient use of waste heat and a downward injection of a burner.

일반적으로 보일러에는 수실(난방수 저장실)이 구비되어 버어너에서 분사된 화염(연소가스)이 연소실을 거쳐 연도로 배출되는 동안 수실내의 물이 고온으로 덥혀지므로써 난방이 실시되는 것이며, 또한 수실내에는 별도의 급탕용 배관을 코일형으로 설치하여 급탕용으로써 온수를 빼내어 사용할수 있도록 되어 있는바, 종래의 보일러는 버어너에서 분사되는 화염이 상향 또는 수평방향으로 분사되도록 하였기 때문에 화실 및 연소실에서의 연소가스 상승속도가 가속되어 연도로 직접 배출되기 때문에 수실과의 열교환이 충분하게 이루어지지 못하므로써 열효율이 저하되고, 상대적으로 연료의 소비량 증대를 가져오게 되는등의 문제점이 있있으며, 또한 불완전 연소가스의 대기방출로 주택공간의 환경오염을 가중시키는 일요인이 되어 왔었다.In general, the boiler is equipped with a water chamber (heating water storage chamber), and the water in the chamber is heated to a high temperature while the flame (combustion gas) injected from the burner is discharged to the flue through the combustion chamber. In the room, a separate hot water supply pipe is installed in a coil type so that hot water can be extracted and used for hot water. In the conventional boiler, since the flame sprayed from the burner is sprayed upward or horizontally, As the rising rate of combustion gas accelerates and is discharged directly to the year, there is a problem such that heat efficiency with the water chamber is insufficient, resulting in a decrease in thermal efficiency and relatively high fuel consumption, and incomplete combustion. Gas emissions have been a major factor in increasing environmental pollution in residential spaces.

본 고안은 상기와 같은 종래의 일반적인 보일러가 갖는 제반 문제점, 즉 버어너로 그대로 유입되는 차가운 공기로 인한 열효율 저하 문제 및 버어너의 상향식 분사로 인한 연소가스의 직배출 문제를 감안하여 수실의 열전달 면적을 극대화함은 물론, 수신상부에 설치되는 급탕 탱크의 내부로 폐열회수실을 설치하여 급탕 탱크로 들어오는 냉수의 예열이 이루어지도록 하되, 수실상부에 공기 예열기를 설치하여 버어너로 유입되는 공기의 예열이 실시되도록 안출한 것으로, 이를 첨부도면에 의거 상세히 설명하면 다음과 같다.The present invention is a heat transfer area of the chamber in consideration of all the problems of the conventional boiler as described above, that is, the heat efficiency deterioration due to cold air flowing into the burner and the direct discharge of the combustion gas due to the bottom-up injection of the burner In addition, the waste heat recovery chamber is installed inside the hot water tank installed at the upper part of the receiving water to preheat the cold water coming into the hot water tank. Preheated to be carried out, which will be described in detail based on the accompanying drawings as follows.

난방용 수실 상부에 급탕 탱크를 구비시켜 보일러를 구성하되, 급탕탱크(1)의 내중앙으로 폐열 회수실(4)을 형성하며, 급탕탱크(1)와 연결되는 급탕라인(5)을 수실(6) 내부로 권취시켜 급탕탱크(1)내의 급탕수의 예열이 이루어지도록한 가정용 온수 보일러에 있어서, 수실(6)의 내중앙 상부에 하향 분사식 화실(7)을 설치하고, 수실(6)에 형성된 연소가스 상승통로(9)의 직상부에 환형상의 공기예열기(11)를 근접 설치하여 열효율의 극대화 및 에너지 절약이 이루어지도록 한 것으로, 상기 수실(6)과 페열회수실(4) 사이에는 연소가스 상승통로(9)를 빠져나온 연소가스가 폐열회수실(4)로 유도될 수 있도록 유도판(12)이 설치되어 있으며, 화실(7)의 직하방 연소실 바닥에는 내화벽돌(10)이 적재되어 있다.The boiler is formed by providing a hot water tank on the upper side of the heating chamber, and a waste heat recovery chamber 4 is formed at the center of the hot water tank 1, and the hot water line 5 connected to the hot water tank 1 is connected to the water chamber 6 In the domestic hot water boiler in which the hot water is preheated in the hot water tank (1), a downward injection fire chamber (7) is installed in the upper center of the water chamber (6), and the water chamber (6) is formed in the water chamber (6). The annular air preheater 11 is installed in the upper portion of the combustion gas rising passage 9 to maximize the thermal efficiency and save energy. The combustion gas is disposed between the water chamber 6 and the waste heat recovery chamber 4. An induction plate 12 is installed to guide the combustion gas exiting the ascending passage 9 into the waste heat recovery chamber 4, and the refractory brick 10 is mounted on the bottom of the combustion chamber directly below the fire chamber 7. have.

도면중 미설명부호; 13은 보일러 지지벽체, 14는 연결관이다.Unexplained reference numerals in the drawings; 13 is a boiler support wall and 14 is a connection pipe.

이와같이 구성된 본 고안의 작용효과를 설명하면, 버어너(16)에서 화염이 발사되면 그 화염은 화실(7)에서 유로변경되어 보일러의연소실(2) 바닥을 향하여 화염이 하강하게 되는바(하향식 분사), 이와같이 하향 발사된 화염에 의하여 주의에 길게 종설된 2중튜브(3)의 집중 가열이 실시됨과 동시에 연소실 바닥 중앙에 적재된 내화벽돌에 부딕쳐 분산되는 화염에 의하여 또다시 수실에서 길게 종설된 튜브(3)를 가열하게 된다.Referring to the effect of the present invention configured as described above, when the flame is fired in the burner 16, the flame is changed in the flow path in the fire chamber (7) so that the flame falls toward the bottom of the combustion chamber (2) of the boiler (downward injection In this manner, concentrated heating of the double tube 3, which is long attentively carried out by the downwardly fired flame, is carried out, and at the same time, it is further lengthened in the chamber again by a flame that is scattered by the fire bricks loaded at the center of the combustion chamber. The tube 3 is heated.

또한, 이렇게 수실을 가열하고 난 연소가스는 연소실 바닥에 근접되며 길게 종설된 각 튜브(3)의 연소가스 상승통로(9)를 통하여 상승하게 되고, 이 과정에서 또다시 튜브(3)의 재가열이 실행되면서 수실내의 물을 가열시키게 되는 것으로, 이와같이 하향 발사된 연소가스가 각 튜브에 형성된 연소가스 상승통로(9)를 통하여 연소가스 유도판(12)쪽으로 상승되는과정에서 연소가스의 흐름 속도 지연이 이루어져 연소가스의 완전연소가 가능하게 되는 것이다.In addition, the combustion gas after heating the water chamber rises through the combustion gas rising passage 9 of each tube 3 which is long and close to the bottom of the combustion chamber, and in this process, the reheating of the tube 3 is again performed. As it is executed, the water in the chamber is heated, and the combustion gas flow rate is delayed in the process of rising downward toward the combustion gas guide plate 12 through the combustion gas rising passage 9 formed in each tube. This makes it possible to completely burn the combustion gas.

한편, 각 튜브(3)의 연소가스 상승통로(9)를 빠져나온 연소가스는 그 위에 근접되게 설치된 환상의 공기예열기(11)를 집중 가열하면서(여기서 1차 폐열회수가 이루어짐) 연소가스 유도판(12)에 유도되어 그 상부의 급탕탱크(1) 내부에 마련된 폐열회수실(4)로 상승 진입하게 되므로써 급탕탱크(1)내의 급탕수를 예열시킬 수가 있게 되는 것으로(여기서 2차 폐열회수가 이루어짐).On the other hand, the combustion gas exiting the combustion gas rise passage 9 of each tube 3 is the combustion gas induction plate while heating the annular air preheater 11 installed in close proximity therewith (first waste heat recovery is performed). The hot water in the hot water tank (1) can be preheated (wherein the second waste heat recovery) by being led to (12) and entering the waste heat recovery chamber (4) provided in the upper hot water tank (1). Done).

본 고안에서는 버어너(7)로 유입되는 공기예열기(11)를 형성함에 있어서, 그 단면형상을""형으로 형성함으로써 열접촉 면적을 확대시킬수도 있다.In the present invention, in forming the air preheater 11 flowing into the burner 7, its cross-sectional shape is " It is possible to enlarge the thermal contact area by forming a ".

수실(6)과의 열교환을 끝내고, 폐열회수실(4)로 진입된 폐연소가스는 원래 연도(15)로 직배기되어야 할 가스인바, 본 고안에서는 아직도 고열을 간직하고 있는 폐연소가스를 다시 급탕탱크(1)내의 폐열 회수실(4)로 그 유로를 변경시킴으로써 폐연소 가스가 가지고 있는 열로써 냉수가 보충된 급탕탱크(1)내의 차거운 물이 미리 예열되도록 하여 급탕라인(5)이 수실(6)을 거치면서 보다 빠른 시간안에 뜨겁게 덥혀질수 있도록 한것이며, 보일러 내부에 버어너 공기를 예열할 수 있는 장치를 설치함으로써 보일러의 외관을 헤치지 않으면서 버어너로 공급되는 공기의 예열이 이루어지도록 하여 열효율을 배가시킬수 있게 되는 것이다.After the heat exchange with the water chamber (6), the waste combustion gas entered into the waste heat recovery chamber (4) is a gas which should be directly vented to the flue (15), and in the present invention, the waste combustion gas which still has high heat is returned. By changing the flow path to the waste heat recovery chamber 4 in the hot water supply tank 1, the hot water in the hot water supply tank 1 supplemented with cold water by the heat of the waste combustion gas is preheated in advance so that the hot water supply line 5 receives the water chamber. Through (6), it can be heated up in a shorter time, and by installing a device to preheat burner air inside the boiler, the air supplied to the burner is preheated without damaging the appearance of the boiler. It will be able to double the thermal efficiency.

이와같이 본 고안에서는 하향시 버어너 구조와 공기 예열기를 구비함으로써 연소실의 집중 가열과 연소가스의 흐름속도를 지연시켜 연소가스의 완전연소가 실현되도록 하고, 버어너로 공급되는 차거운 공기를 미리 예열시켜 보일러의 열효율을 높이고 에너지를 대폭 절감시킬 수 있는 효과가 있는 것이며, 또한 연소가스의 완전연소로 인한 주택환경의 오염문제를 최소화할 수 있는 등 그 실사용 가치가 일층 고양된 신규의 고안인 것이다.Thus, in the present invention, the burner structure and the air preheater are provided in the downward direction, so that the intensive heating of the combustion chamber and the flow rate of the combustion gas are delayed so that the complete combustion of the combustion gas is realized. It is a new design that enhances the thermal efficiency and significantly reduces energy, and minimizes the pollution problem of the housing environment due to the complete combustion of combustion gas.
