본 발명은 저 산소 소용돌이 버너에 관한 것으로서, 더욱더 상세하게는 보일러의 내연기관에서 발생되는 배기가스를 연소공기 공급원으로 사용하여 재연소가 이루어지도록 함으로써, 배기가스를 완전연소된 상태로 배출되도록 하고, 자연환경이 배기가스에 의해 오염되는 것이 억제되도록 하는 저 산소 소용돌이 버너를 제공하는 데 있다.The present invention relates to a low oxygen vortex burner, and more particularly, by using the exhaust gas generated in the internal combustion engine of the boiler as a combustion air source to be re-burned, to exhaust the exhaust gas in a completely burned state, It is to provide a low oxygen vortex burner to suppress the pollution of the natural environment by the exhaust gas.

일반적으로 내연기관(內燃機關)이라 함은 실린더 속에 연료를 공급한 후, 연소 폭발시켜서 생긴 가스의 팽창력으로 피스톤을 움직이게 하는 원동기를 통틀어 이르는 것이고, 보일러(boiler)라 함은 물을 가열하여 고온, 고압의 증기나 온수를 발생시키는 장치로서, 난방 시설이나 목욕탕, 터빈 구동 등에 사용되는 것은 주지된 사실이다.In general, an internal combustion engine refers to a prime mover that moves a piston by the expansion force of a gas generated by combustion and explosion after supplying fuel into a cylinder, and a boiler refers to a high temperature, As a device for generating high pressure steam or hot water, it is well known to be used in heating facilities, bathhouses, turbine drives, and the like.

또한, 보일러 겸용 내연기관이라 함은, 상기 내연기관의 냉각수 폐열과 배기가스의 열을이용하여 보일러를 사용할 수 있도록 한 것으로서, 이는 보일러를 사용하기 위하여 별도의 연소기관이 필요없이 내연기관으로부터 연소열과 물을 공급받으므로에 너지절약을 할 수 있는 것이며, 상기 보일러에 증기터빈을 설치하게 되면 그 증기터빈 으로 부터 별도의 동력원을 창출할 수 있도록 하는 것이다.In addition, the boiler combined internal combustion engine is to enable the boiler to be used by using the waste heat of the cooling water and the heat of the exhaust gas of the internal combustion engine, which means that the combustion heat from the internal combustion engine does not need a separate combustion engine to use the boiler. Energy can be saved by receiving water, and if a steam turbine is installed in the boiler, a separate power source can be created from the steam turbine.

이와 같은 종래의 보일러 겸용 내연기관은 크게 내연기관과 수냉자켓과 보일러와 증기터빈과 순환펌프를 포함한 냉각수 순환구조와 내연기관의 배기가스가 배출되는 배기관의 끝단에 부착되고 보일러의 내부에 설치되는 가열관으로 구성되는바, 상기 내연기관을 냉각시킨 후 가열된 고온의 냉각수는 상기 보일러로 유입되는 한편, 내연기관 으로 부터 배출되는 배기가스가 배기관을 거쳐 상기 보일러 내부에 설치된 가열관을 지나면서 보일러를 가열시키게 되므로, 상기 보일러에 유입된 고온의 냉각수가 뜨거워지면서 증기를 발생하게 되며, 이때 발생된 증기는 증기터빈 을 구동한 후 응결되어 순환펌프를 통해 다시 내연기관을 냉각시키기 위한 수냉자켓으로 유입되는 순환과정을 반복하는 것이다.Such conventional boiler combined internal combustion engine is largely attached to the cooling water circulation structure including the internal combustion engine, the water cooling jacket, the boiler, the steam turbine and the circulation pump, and the exhaust pipe from which the exhaust gas of the internal combustion engine is discharged, and is installed inside the boiler. It consists of a tube, the high temperature cooling water heated after cooling the internal combustion engine is introduced into the boiler, while the exhaust gas discharged from the internal combustion engine passes through the exhaust pipe through the heating tube installed inside the boiler to maintain the boiler Since it is heated, the hot cooling water introduced into the boiler is heated to generate steam, and the generated steam is condensed after driving the steam turbine is introduced into the water cooling jacket for cooling the internal combustion engine again through the circulation pump It is to repeat the cycle.

그러나, 이와 같은 구조에 의하면 상기 보일러에 저장된 냉각수를 가열시 내연기관에서 발생된 배기가스가 대기중으로 그대로 배출되어 공기를 오염시키게 됨은 물론, 자연환경을 파손하게 되는 문제점이 있었다.However, according to such a structure, when the cooling water stored in the boiler is heated, the exhaust gas generated from the internal combustion engine is discharged into the atmosphere to pollute the air, and there is a problem of damaging the natural environment.

An object of the present invention is to solve the problem as described above, by using the exhaust gas discharged from the internal combustion engine as a source of combustion air so that the cooling water flowing into the boiler is heated again, so that the thermal efficiency of the boiler is further improved. At the same time, the exhaust gas is completely burned and discharged, thereby providing a low oxygen vortex burner that suppresses contamination of the natural environment by the exhaust gas.

상기 노즐(500)의 끝부분에는 외통(200) 내부로 유입된 배기가스와 노즐(500)을 통해 분사되는 연료가 혼합된 상태에서 빠른 속도로 통과되면서 연소실(120)로 공급되어 연소가 이루어지도록 하는 오리피스(800)가 형성된다.At the end of the nozzle 500, the exhaust gas introduced into the outer cylinder 200 and the fuel injected through the nozzle 500 are mixed at a high speed to be supplied to the combustion chamber 120 to be combusted. An orifice 800 is formed.

상기 연소실(120)의 일측에 위치하는 오리피스(800)의 반대편에는 연소시 발생된 화염이 연소실(120)의 내부로 재순환되도록 하는 쵸크(700)가 형성되고, 상기 쵸크(700)가 형성되어 있는 연소실(120)의 내부에는 배기가스와 혼합되어진 연소연료에 방사열을 전달함과 동시에 연소실(120)을 형성하고 있는 외부틀(100)이 화염에 의해 변형되지 않도록 하는 내화물(600)이 쵸크(700)와 오리피스(800)를 제외한 나머지 부분을 감싸도록 설치된다.On the opposite side of the orifice 800 located on one side of the combustion chamber 120, a choke 700 is formed so that the flame generated during combustion is recycled into the combustion chamber 120, and the choke 700 is formed. In the combustion chamber 120, the refractory 600, which transmits radiant heat to combustion fuel mixed with exhaust gas and prevents the outer frame 100 forming the combustion chamber 120 from being deformed by a flame, is choked 700. And is installed to surround the remaining portion except the orifice (800).

물론, 상기 유입공간(110)에는 보일러 겸용 내연기관의 배기가스가 배출되는 배기관에 연결이 이루어지는 연결공(111) 관통되게 일측부에 형성되어 있어, 상기 내연기관으로 부터 배출되는 배기가스가 배기관을 거쳐 유입공간(110)으로 유입되어지게 됨을 밝혀 둔다.Of course, the inlet space 110 is formed in one side through the connecting hole 111 is connected to the exhaust pipe discharged from the exhaust gas of the boiler combined internal combustion engine, exhaust gas discharged from the internal combustion engine It turns out that the inflow space 110 is introduced through.
