The present invention relates to a combustion system having a water-cooled oxygen automatic burner and a powder melting apparatus which can continuously supply combustion gas, compressed air, and oxygen without a furnace, so that efficient oxygen combustion can occur.
또한 본 발명의 일실시예에 따른 수냉식 산소자동버너와 분말용융장치를 갖는 연소시스템의 구조는 고온에서의 변형손상을 방지하도록 냉각수를 이중관에서 순환시켜 수냉식으로 냉각하도록 하였고, 연료를 버너 본체 후단 중심에서 점화장치를 내장하여 자동으로 착화되도록 하였으며, 압축공기를 동시에 공급하여 연소가 잘되도록 하였고, 산소가 공급되는 공급단을 분출단측으로 점진적으로 직경을 증가시켜 산소분출을 다단식으로 하여 초음속의 화염(약 3000℃)이 발생되어 분출하도록 하였다. In addition, the structure of the combustion system having a water-cooled oxygen automatic burner and a powder melting apparatus according to an embodiment of the present invention circulates the coolant in a double pipe to prevent water damage at high temperature, and cools the water in a water-cooled manner. The ignition device was built in to ignite automatically, and the combustion air was supplied by supplying the compressed air at the same time, and the supply stage where oxygen was supplied was gradually increased in diameter to the ejection end, and the oxygen ejection was made in multiple stages so that the flame of supersonic ( About 3000 [deg.] C. was generated and allowed to eject.
이때 분말공급장치에서 고체분말을 공급하여 고온의 화염과 충돌시켜 연소실에서 용융되어 액체상태로 흐르게 되고, 캐스타불이나 전지물로 원통모양으로 제작된 포집단으로 흘러나오게 됨으로써 로가 없이 제품을 제조, 생산할 수 있다. 이때 용융믈의 양과 재질에 따라 보조산소버너를 장착하여 열 공급의 냉각을 방지할 수 있고, 또하느 연소실 일측에 화염감지기 장착하여 화염을 감시, 착화 실화를 방지함으로써 자동적으로 사용할 수 있도록 하였다. At this time, the powder supply device supplies the solid powder, collides with a high temperature flame, melts in the combustion chamber, flows into a liquid state, and flows out into a collection made of a cylindrical shape with caster or battery, thereby producing a product without a furnace. , Can produce. At this time, the auxiliary oxygen burner can be installed according to the amount and material of molten melt to prevent cooling of the heat supply, and the flame detector is installed at one side of the combustion chamber to monitor the flame and prevent the ignition fire.
일반적으로 산소부화 연소는 연료의 연소시 기존의 공기 대신에 공기중에 산소를 혼입시켜 공기중의 산소농도를 높여 주는 것으로서 화염의 온도가 상승하고 전열효율이 향상되며 연소가스량이 감소되는 연료절약형 연소기술이다. 공기중에는 산소가 21%, 질소가 79% 함유되어 있으나, 산소를 공기에 혼합시켜 산소부화를 시키면 공기중 산소의 농도는 증가되고 질소의 농도는 감소하므로 연소가스의 양이 대폭적으로 저감된다. 산소부화율 1% 증가당(예, 공기중 산소농도가 21%에서 22%로 된다면) 1.2%의 연료절감이 가능하다고 보고되고 있으며, 따라서 산소부화율을 증가시키면 열효율도 동반 상승되는 효과가 있다.In general, oxygen-enriched combustion improves the oxygen concentration in the air by incorporating oxygen into the air instead of the existing air when the fuel is burned. Fuel-saving combustion technology that increases the flame temperature, improves heat transfer efficiency, and reduces the amount of combustion gas. to be. The air contains 21% oxygen and 79% nitrogen. However, when oxygen is mixed with air to enrich the oxygen, the concentration of oxygen in the air increases and the concentration of nitrogen decreases, thereby greatly reducing the amount of combustion gas. It is reported that 1.2% of fuel can be saved per 1% increase in oxygen enrichment rate (for example, if oxygen concentration in air is 21% to 22%). Therefore, increasing oxygen enrichment rate also increases thermal efficiency.
통상의 산소버너는 연료와 산소를 노즐에서 분출시켜 혼합연소하게 된다. 따라서, 산화반응속도가 느리게 되어 연소가 되기 전에 로에서 배출되므로 에너지 손실률이 크게 된다. 통상적인 산소버너는 중공관 형태의 로의 입력단이 연료탱크와 연결되어 연료 공급부에 의해 로 내로 연료가 공급되게 된다. Conventional oxygen burners are used to eject fuel and oxygen from nozzles for mixed combustion. Therefore, the oxidation reaction rate is slowed down and discharged from the furnace before combustion, the energy loss rate is large. In the conventional oxygen burner, an input terminal of a hollow tube type furnace is connected to a fuel tank so that fuel is supplied into the furnace by a fuel supply unit.
그리고, 고압공기 공급부에 의해 로 내로 일정량의 산소가 포함된 압축기에서 압축된 고압공기를 유입시켜 고압공기가 혼합된 연료가 연소관으로 유입되어 연소관에서 혼합되어 연소관에 설치된 점화장치에 의해 점화, 연소하게 됨으로써 화염을 발생시키게 된다. 그러나, 이러한 방식을 사용하는 경우, 연료를 완전연소시킬 수 없고, 연소반응속도가 느리고, 고온의 화염온도를 얻을 수 없어, 연소효율이 좋지 않고, 배기가스량이 많아 에너지 손실이 크다는 문제가 존재한다. 또한, 화염온도를 높이는데 한계가 존재하기 때문에, 그 적용범위가 작다는 문제가 존재한다.Then, the high pressure air is supplied into the furnace by the high pressure air supply unit, and the compressed high pressure air is introduced from the compressor including a certain amount of oxygen into the furnace. As a result, a flame is generated. However, when such a method is used, there is a problem in that fuel cannot be completely burned, combustion reaction rate is slow, and a high flame temperature is not obtained, combustion efficiency is not good, and the amount of exhaust gas is large, resulting in large energy loss. . In addition, since there is a limit to increasing the flame temperature, there is a problem that its application range is small.
온도를 고온으로 발생시키기 위해, 공기를 가열하여 공급하는 방법이 존재하나 그러기 위해서는 대형의 연소실이 필요하고, 별도의 가열수단 등이 필요하게 되어 소형으로 제작하기가 어렵고, 제작비가 많이 소요되어 경제적이지 않다는 문제가 존재하게 된다. 또한, 기존의 산소버너는 완전연소가 되기 어려워 연소시 일산화탄소, 다이옥신, 등의 유해물질이 발생되는 문제가 있다. In order to generate the temperature at a high temperature, there is a method of heating and supplying air, but in order to do so, a large combustion chamber is required, and a separate heating means is required, so it is difficult to manufacture small and economical because it requires a lot of manufacturing cost. There is a problem. In addition, the existing oxygen burner is difficult to be completely burned, there is a problem that harmful substances such as carbon monoxide, dioxins, etc. are generated during combustion.
또한, 점화장치를 연소실, 연소관에 수직형 또는 수평형으로 별도로 설치하거나 수동으로 점화를 하거나, 별도의 착화장치(예를 들어, 파이롯트 버너)를 설치해야하므로 장치 설치비가 경제적이지 않고, 설치하는 것 자체가 불편하고, 사용하기 불편한 문제점이 존재하였다. In addition, since the ignition device must be installed separately in the combustion chamber, the combustion pipe vertically or horizontally, or ignited manually, or a separate ignition device (for example, a pilot burner) must be installed, the installation cost of the device is not economical, and it is to be installed. Inconvenient itself, there was a problem inconvenient to use.
따라서, 소형으로 제작이 가능하면서도 고온의 화염온도를 발생시키고, 배기가스, 유해가스의 배출을 감소시킬 수 있으며, 점화가 신속하게 일어날 수 있고, 설치비용을 감소시키고, 유지관리가 간편한 점화장치 일체형 산소버너의 개발이 요구되었다. Therefore, it is possible to manufacture small size, but also generate high flame temperature, reduce the emission of exhaust gas and harmful gas, ignition can occur quickly, reduce the installation cost, easy to maintain the integrated ignition device Development of an oxygen burner was required.

The present invention is derived to solve the above problems, according to one embodiment of the present invention, while oxygen and compressed air, combustion gas and the fuel for ignition are supplied in close proximity, the ignition occurs quickly, Since oxygen, compressed air, and combustion gas are simultaneously supplied in close proximity, they can be detonated and generate supersonic high-temperature flames, resulting in improved combustion efficiency by complete combustion and reduced exhaust gas volume. The purpose is to provide.
또한, 점화장치는 연소가스공급관의 내부에 삽입되어 설치되므로, 장비가 저렴하고, 사용이 편리하며, 탈부착이 자유로워 유지관리가 편리한 점화장치 일체형 산소버너를 제공하는 것을 그 목적으로 하고 있다.
