본 고안은 역화 방지용 버너구조에 관한 것으로, 특히 버너헤드 중앙에는 역화 방지 캡을 삽입하여 혼합관 내측의 역화를 방지하는 역화방지용 버너구조에 관한 것이다.The present invention relates to a flashback prevention burner structure, and more particularly to a flashback prevention burner structure to prevent the flashback inside the mixing tube by inserting a flashback prevention cap in the center of the burner head.

종래의 버너는 제2도에 도시된 바와 같이 버너바디(4)와 일체로 형성된 혼합관(2) 하측에는 가스공급관과 연결된 노즐(14)을 설치하고, 상기 버너바디(4) 상측에는 방사형의 다수염공이 형성된 버너헤드(6)를 재치하고, 버너헤드(6)의 상측에는 버너캡(12)을 올려 놓은 구성을 나타낸다.The conventional burner is provided with a nozzle 14 connected to the gas supply pipe under the mixing pipe 2 formed integrally with the burner body 4, as shown in FIG. 2, and a radial shape on the burner body 4 above. The burner head 6 in which the multiple flame holes were formed is mounted, and the burner cap 12 is mounted on the burner head 6, and the structure is shown.

이와 같이 구성된 종래의 버너는 가스공급관에 연결된 노즐(14)에서 분사되는 분출가스는 혼합관(2)을 지나 1차 공기와 혼합되어 버너헤드(6)의 염공으로 분출되게 되는데, 이때 혼합관(2) 상측과 버너헤드(6) 저면사이에 형성되는 공간의 혼합실(5)의 면적이 넓어 버너의 소화시 혼합실(5)의 잔류 가스로 인한 역화 현상이 발생되었다.In the conventional burner configured as described above, the ejected gas injected from the nozzle 14 connected to the gas supply pipe is mixed with the primary air through the mixing pipe 2 to be ejected into the salt hole of the burner head 6, wherein the mixing pipe ( 2) The area of the mixing chamber 5 of the space formed between the upper side and the bottom of the burner head 6 is wide, and a backfire phenomenon due to the residual gas in the mixing chamber 5 occurs when the burner is extinguished.

또한, 혼합관(2) 저부에서 일정압으로 분출되는 가스는 버너헤드의 저면과 부딪친 후 버너헤드(6)의 염공으로 분출될 때, 와류현상이 일어나 원할한 가스흐름이 되지 못하여 화염이 불완전 연소가 되는 경우가 빈발하였다.In addition, when the gas ejected at a constant pressure from the bottom of the mixing pipe (2) hits the bottom of the burner head and is ejected into the salt hole of the burner head (6), the vortex phenomenon occurs to prevent the desired gas flow, resulting in incomplete combustion of the flame. It was frequently the case that

이에 본 고안은 상기와 같은 제반 문제점을 해소하기 위하여 안출된 것으로, 버너헤드 중앙에는 삽입홀을 천공한 후 삽입홀에는 역화 방지캡을 삽입 설치하여 혼합관 상측과 버너헤드 저면사이의 공간부에 형성된 혼합실의 넓이를 최소화하므로서, 버너의 소화시 상기 혼합실의 잔류 가스를 최소화하여 역화를 방지할 수 있는 역화 방지용 버너 구조를 제공함에 목적이 있다.In order to solve the above problems, the present invention is conceived, and the insertion hole is drilled in the center of the burner head, and then the backfire prevention cap is inserted into the insertion hole and formed in the space between the upper side of the mixing tube and the bottom of the burner head. By minimizing the width of the mixing chamber, it is an object of the present invention to provide a burner prevention burner structure that can prevent backfire by minimizing the remaining gas in the mixing chamber when extinguishing a burner.

또한, 본 고안의 다른 목적은 혼합관 저부에서 일정 압력으로 분출되는 가스가 혼합관 내에서 1차 공기와 혼합된 후 역화 방지캡의 경사면을 따라 버너헤드의 염공으로 분출되므로서, 혼합가스의 통로를 형성하므로서 원활한 가스흐름이 되게 하여 화염이 완전연소할 수 있도록 한 목적이 있다.In addition, another object of the present invention is that the gas ejected at a constant pressure in the bottom of the mixing tube is mixed with the primary air in the mixing tube is ejected into the salt hole of the burner head along the slope of the flashback prevention cap, the passage of the mixed gas The purpose is to make a smooth gas flow by forming a so that the flame can be completely burned.

상기한 바와 같은 목적을 달성하기 위한 본 고안은 버너바디와 일체로 형성된 혼합관 하측에는 가스공급관과 연결된 노즐을 설치하며, 상기 버너바디 상측에는 상면에 다수염공을 가진 버너헤드를 재치하고, 버너헤드 중심에는 삽입홀을 천공하여 삽입홀에는 하측에 경사면이 형성된 역화 방지캡을 삽입하며, 상기 버너헤드 상측에는 버너캡을 올려놓은 것이다.The present invention for achieving the above object is provided with a nozzle connected to the gas supply pipe in the lower side of the mixing tube formed integrally with the burner body, the burner head having a burner head having a number of salt holes on the upper side, the burner The insertion hole is drilled in the center of the head to insert a flashback prevention cap having an inclined surface at the lower side of the insertion hole, and a burner cap is placed on the burner head.

이하 본 고안을 첨부된 도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안의 버너를 도시한 단면도로서, 버너바디(4) 하측에는 일체로 혼합관(2)을 형성하고, 혼합관(2)의 저부에는 1차공기 투입구 및 가스공급관과 연결노즐(14)을 설치하며, 상기 버너바디(4) 상측에는 상면에 다수의 염공이 방사형으로 형성된 버너헤드(6)를 재치시키는 한편, 이 버너헤드(6) 중앙에는 삽입홀을 천공시켜 위에서 아래로 하측에 경사면(10)을 가진 역화 방지캡을 삽입 설치하므로서, 버너헤드(6) 저면과 혼합관(2) 사이 공간에 형성된 혼합실(5)의 면적을 최소화하는 것이다.1 is a cross-sectional view showing a burner according to the present invention, in which a mixing pipe 2 is integrally formed under the burner body 4, and a primary air inlet, a gas supply pipe, and a connecting nozzle are formed at the bottom of the mixing pipe 2; 14) and burner head 6 having a plurality of flame holes formed radially on the upper surface of the burner body 4, while the insertion hole is drilled in the center of the burner head 6, and the lower side from top to bottom. By inserting the flashback prevention cap having the inclined surface 10 in the installation, the area of the mixing chamber 5 formed in the space between the bottom of the burner head 6 and the mixing pipe 2 is minimized.

또한 상기 버너헤드(6) 상측에는 버너캡(12)의 올려 놓은 것을 나타낸다.In addition, the burner cap 12 is placed on the burner head 6.

상기와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

제1도에 도시된 바와 같이 혼합관(2) 하측에 가스공급관과 연결된 노즐(14)에서 가스가 분출되면 1차 공기 투입부에서 공급되는 공기와 가스는 혼합관 내부에서 섞여 밖으로 분출되는데, 이때 역화방지캡(8) 저부의 경사면(10)을 따라 혼합가스는 외측으로 넓게 확장되어 버너헤드(6) 상면에 형성된 염공으로 원활히 분출된다. 그러므로서 염공으로 분출된 혼합가스는 분출속도가 일정하여 화염 상태가 완전연소 상태로 되는 것이다.As shown in FIG. 1, when the gas is ejected from the nozzle 14 connected to the gas supply pipe under the mixing pipe 2, the air and the gas supplied from the primary air inlet are mixed inside the mixing pipe and blown out. Along the inclined surface 10 of the bottom of the flashback prevention cap 8, the mixed gas is extended to the outside and is smoothly ejected into the salt holes formed on the burner head 6 upper surface. Therefore, the mixed gas ejected into the salt hole has a constant ejection rate so that the flame state is completely burned.

또한, 버너의 소화시 혼합관(2) 상측과 버너헤드(6)의 사이공간에 역화 방지캡(8)을 형성시켜 혼합실(5)의 면적을 최소화하므로서, 혼합실(5)의 잔류가스가 별로 남질 않아 역화를 방지한다.In addition, when the burner is extinguished, a flashback prevention cap 8 is formed in the space between the upper side of the mixing tube 2 and the burner head 6 to minimize the area of the mixing chamber 5, thereby remaining gas in the mixing chamber 5. There is not much left to prevent backfire.

상기와 같은 본 고안은 하측이 경사진 역화방지캡을 혼합실 내부에 설치시켜 혼합가스의 흐름을 원활히 하고, 혼합실의 면적을 최소화하여 잔류 가스를 줄이므로서 역화를 방지하는 효과가 있다.The present invention as described above has the effect of preventing backfire by installing a flashback prevention cap inclined to the lower side to smooth the flow of the mixed gas, and minimize the area of the mixing chamber to reduce the residual gas.
