본 발명은 스팀보일러에 관한 것으로서, 보다 상세히는 연소실 내부에 설치된 열교환 파이프들이 스파이럴 구조로 연결되고 연소실 역시 스파이럴 구조로 되 면서 열효율을 상승시킨 스파이럴 구조의 연소실을 가진 스팀보일러에 관한 것이다.       The present invention relates to a steam boiler, and more particularly, to a steam boiler having a spiral structure in which heat exchange pipes installed inside a combustion chamber are connected to a spiral structure and the combustion chamber is also a spiral structure, thereby increasing thermal efficiency.

통상적으로 스팀보일러는 물을 가열하여 고온의 스팀을 발생시키고 이 발생된 스팀을 이용하는 것으로 난방시설 및 산업용 그리고 음식물 조리용 등에서 널리 사용된다.        In general, a steam boiler generates high temperature steam by heating water, and is widely used in heating facilities, industrial applications, and food cooking.

이러한 스팀보일러는 단열재가 내장된 외통내의 상측과 하측에 증기실과 수실이 형성되고 증기실과 수실 사이에는 다수의 수관을 상하로 입설한 구조로서 연소실내에 유입된 연소열과 연소가스는 바로 상승하며, 연통으로 배출되기 때문에 많은 열이 대기로 즉시 방출되어 버리므로 열효율이 매우 좋지 못하였다.      The steam boiler has a steam chamber and a water chamber formed on the upper side and the lower side of the outer cylinder in which the heat insulating material is built, and a plurality of water pipes are placed vertically between the steam chamber and the water chamber. The heat efficiency was not very good because a lot of heat was immediately released to the atmosphere because it is discharged to the atmosphere.

한편, 대한민국 특허청의 실용신안등록 제 304665호에는 스파이럴 구조의 연소실이 형성된 보일러에는 2개의 격판이 일정한 간격을 두고 외측으로 점차 확산되는 스파이럴 선형을 구성하여 폐열이 거의 없이 열효율을 높이고 있다. 이와 같이 스파이럴 선형을 이용한 보일러는 그 효과가 뛰어나지만 2개의 격판을 일정한 간격으로 배치시키고 고정시키기에 고도의 기술을 요하고 생산성이 낮아 실용화 되는데는 많은 문제점을 가진다.      On the other hand, Utility Model Registration No. 304665 of the Korean Intellectual Property Office has a spiral structure in which the two diaphragms gradually spread outwardly at regular intervals in a boiler in which a combustion chamber of a spiral structure is formed to increase thermal efficiency with little waste heat. As described above, the spiral linear boiler has an excellent effect, but requires a high level of skill and low productivity in order to arrange and fix two diaphragms at regular intervals.

따라서 본 발명은 열효율을 최대한 상승시킬 수 있는 스파이럴 선형을 이용한 스팀보일러를 제안하고자 한다.Therefore, the present invention is to propose a steam boiler using a spiral linear to increase the thermal efficiency as possible.

본 발명은 상술한 종래의 문제점을 극복하기 위한 것으로, 본 발명의 목적 은        The present invention is to overcome the above-mentioned conventional problems, the object of the present invention is

열을 효율적으로 이용하여 단시간에 고온의 스팀을 생산할 수 있으며, 폐열을 감소하여 에너지 소비를 크게 줄일 수 있는 스파이럴 구조의 연소실을 가진 스팀보일러를 제공함에 있다.The present invention provides a steam boiler having a spiral combustion chamber capable of producing high-temperature steam in a short time by using heat efficiently and greatly reducing energy consumption by reducing waste heat.

이하 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.        Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1과 도 2는 본 발명에 따른 스파이럴 구조의 연소실을 가진 스팀보일러의 내부구조를 도시하기 위한 가로방향과 세로방향의 중앙 단면도이다.       1 and 2 are central cross-sectional views in the horizontal and longitudinal directions for illustrating the internal structure of a steam boiler having a spiral combustion chamber according to the present invention.

도면에 따른 본 발명 스파이럴 구조의 연소실을 가진 스팀보일러는 일측의 물 공급관(14)과 상부의 스팀 배출관(16)을 가지는 밀폐형 하우징(10)과, 상기 하우징의 내부로 측면의 고정대(26)에 의해 설치되며 원형의 상판(23)과 하판(24)에 의해 원통형으로 밀폐된 연소실(22)을 가지는 내부 케이싱(20)과, 상기 내부 케이싱의 상판과 하판 사이에 부착되어 수직으로 세워지며 서로 밀착되면서 외측으로 점차 확산되는 스파이럴 선형을 유지하고 있는 열교환 파이프(28)들과, 상기 연소실의 중앙으로 화염 유도관체(32)가 설치되고 여기에 부착되는 버너(30)로 구성된다.       Steam boiler having a combustion chamber of the spiral structure of the present invention according to the drawings is a hermetic housing (10) having a water supply pipe (14) of the one side and the steam discharge pipe (16) of the upper side, and to the fixture 26 of the side into the interior of the housing The inner casing 20 having a combustion chamber 22 cylindrically sealed by a circular upper plate 23 and a lower plate 24, and is attached between the upper plate and the lower plate of the inner casing to stand vertically and closely adhere to each other. And heat exchange pipes 28 which maintain spiral linearity gradually spreading outward, and a burner 30 having a flame guide tube 32 installed at and attached to the center of the combustion chamber.

또한, 상기 연소실(22) 내부에는 외측 끝에 있는 열교환 파이프와 소정의 간격을 두고 방향 전환판(29)이 구비되어 있다.       In addition, the combustion chamber 22 is provided with a diverter plate 29 at predetermined intervals from the heat exchange pipe at the outer end.

위를 더욱 자세하게 설명하면 다음과 같다.       The above is described in more detail as follows.

본체를 구성하는 하우징(10)은 원통형으로 밀폐되어 내부에 수실(12)을 구성한다. 그리고 상기 수실 내부에 물을 공급하기 위한 물공급관(14)이 외부의 수도관과 연결되어 하우징의 하부에 부착되며, 상부에는 스팀 배출관(16)이 부착되어 외부의 스팀사용 장치로 연결된다. 따라서 물 공급관을 통해 물이 수실(12)을 채우게 되고 수실의 상부 즉, 수면 위로는 소정의 증기실(13)을 형성하게 된다.        The housing 10 constituting the main body is hermetically sealed to form a water chamber 12 therein. In addition, a water supply pipe 14 for supplying water into the water chamber is connected to an external water pipe and attached to a lower portion of the housing, and a steam discharge pipe 16 is attached to an upper portion thereof and connected to an external steam using device. Therefore, the water fills the water chamber 12 through the water supply pipe, and forms a predetermined steam chamber 13 above the water chamber, that is, above the water surface.

이후, 상기 하우징 내부에는 그 측면에 부착되는 고정대(26)들에 의해서 내부케이싱(20)이 설치된다. 상기 내부케이싱(20)은 원형의 상판(23)과 하판(24)에 의해서 내부가 밀폐된 것으로 방사상으로 부착되는 고정대(26) 들에 의해서 측면으로 일정한 공간을 두고 그 사이에 물이 채워지게 된다.       Subsequently, the inner casing 20 is installed in the housing by fixing rods 26 attached to the side thereof. The inner casing 20 is sealed by the upper plate 23 and the lower plate 24 in a circular manner, and the water is filled therebetween with fixed spaces 26 fixed to the sides by radially attached fixing rods 26. .

그리고 상기 내부케이싱(20)의 상판(23)과 하판(24) 사이에는 열교환 파이프(28)들이 수직으로 부착되어 수실의 상부와 하부를 관통시킨다. 이때 상기 열교환 파이프들은 서로 밀착되면서 외측으로 점차 확산되는 스파이럴 선형을 유지하고 있다. 이때 내부케이싱(20)의 중앙으로는 소정의 공간부를 두고 연소실(22)이 형성되고, 상기 연소실은 열교환 파이프(28)들을 따라 외측으로 이어지면서 통로(22a)를 구성하게 되며 상기 통로 역시 스파이럴 선형으로 구성된다.        The heat exchange pipes 28 are vertically attached between the upper plate 23 and the lower plate 24 of the inner casing 20 to penetrate the upper and lower portions of the chamber. At this time, the heat exchange pipes maintain spiral spirals that are in close contact with each other and gradually spread outwards. At this time, the combustion chamber 22 is formed in the center of the inner casing 20 with a predetermined space, and the combustion chamber extends outward along the heat exchange pipes 28 to form a passage 22a, and the passage is also spiral linear. It consists of.

한편 상기 연소실(22) 내부에는 도 2에서와 같이 외측 끝에 있는 열교환 파이프와 소정의 간격을 두고 반원형으로 된 방향 전환판(29)이 설치된다. 상기 방향 전환판(29)은 제일 바깥측을 형성하고 있는 열교환 파이프의 외측면을 버너의 고열이 통과할 수 있게 하기 위하여 통로(22a)의 방향을 전환시켜주게 된다. 그리고 상기 통로의 끝에는 외부로 연결되는 배기덕트(18)이 설치되어 있다.        On the other hand, inside the combustion chamber 22, as shown in FIG. 2, a direction change plate 29 having a semicircular shape is provided with a heat exchange pipe at an outer end at a predetermined interval. The diverter plate 29 changes the direction of the passage 22a to allow the high heat of the burner to pass through the outer surface of the heat exchange pipe forming the outermost side. At the end of the passage, an exhaust duct 18 is connected to the outside.

다음, 하우징의 상부에는 내측으로 향하여 화염 유도관체(32)가 설치되어 연소실(22) 중앙으로 연결되게 하며, 화염 유도관체 외부에는 버너(30)가 설치된다.       Next, the flame guide tube 32 is installed in the upper portion of the housing to be connected to the center of the combustion chamber 22, and the burner 30 is installed outside the flame guide tube.

이와 같이 구성되는 본 발명 스파이럴 구조의 연소실을 가진 스팀보일러는 다음과 같이 작동된다.       The steam boiler having the combustion chamber of the spiral structure of the present invention configured as described above is operated as follows.

먼저 물 공급관(14)을 통하여 하우징 내부 수실(12)에 물을 채운다. 상기 물은 내부케이싱(20)이 잠길 수 있게 있게 충분히 채우는 것이 바람직하나 상부에 증기실(13)이 형성될 수 있는 공간을 가지게 한다. 이때 각 열교환 파이프 내부에도 물이 채워지게 된다.        First, water is filled in the water chamber 12 inside the housing through the water supply pipe 14. The water is preferably filled sufficiently so that the inner casing 20 can be submerged, but has a space in which the vapor chamber 13 can be formed. At this time, water is also filled in each heat exchange pipe.

이후 버너(30)를 가동시켜 연소실을 가열하게 되면 연소실 내부의 화염 및 고열이 스파이럴의 통로(22a)를 따라 외측으로 이동하면서 열교환 파이프(28)와 열교환하게 되고 각 열교환 파이프(28) 내부의 물이 가열되기 시작한다. 이후 열교한 파이프 내부의 가열된 물은 대류에 의해 위로 이동하게 되면서, 고온의 증기를 발생케하고 증기실에 집하된 증기는 스팀배출관(16)을 통해 외부로 이동하며 사용목적에 따라 사용된다.        Then, when the combustion chamber is heated by operating the burner 30, the flame and high heat inside the combustion chamber move outward along the spiral passage 22a to exchange heat with the heat exchange pipe 28 and the water in each heat exchange pipe 28. It starts to heat up. Since the heated water inside the thermal bridge pipe is moved up by the convection, the hot steam is generated and the steam collected in the steam chamber is moved to the outside through the steam discharge pipe 16 and used according to the purpose of use.

한편 수실 내부에는 레벨 게이지(도면에 도시생략)가 부착되어 물공급관의 밸브를 제어하게 되면서 수실의 수위를 항상 일정하게 유지시키게 되며, 온도감지센서(도면에 도시생략)를 두어 배출되는 스팀의 온도를 설정할 수 있게 된다.       On the other hand, a level gauge (not shown in the drawing) is attached to the inside of the water chamber to control the valve of the water supply pipe so that the water level of the water chamber is kept constant at all times, and a temperature sensor (not shown in the drawing) is placed to discharge the steam temperature. Can be set.

이상으로 살펴본 바와 같이 본 발명에 따른 스파이럴 구조의 연소실을 가진 스팀보일러는, 연소실의 고열이 스파이럴 구조를 따라 이동하면서 열교환 파이프들과 열교환을 가지게 되어 최종적으로 배출되는 폐열에는 잠열이 거의 없게 되는 것으로 열이 효율적으로 이용되어 에너지의 손실이 거의 없으며, 단시간에 고온의 스팀을 얻을 수 있는 효과가 있다.       As described above, the steam boiler having the combustion chamber of the spiral structure according to the present invention has a heat exchange with the heat exchange pipes while the high temperature of the combustion chamber moves along the spiral structure, so that there is almost no latent heat in the waste heat finally discharged. It is effectively used, so there is almost no loss of energy, and there is an effect of obtaining hot steam in a short time.
