깔때기형 점화기가 설치된 파일럿 버너Pilot burner with funnel igniter

본 고안은 파일럿 버너의 점화기(ignitor)에 관한 것으로, 보다 상세하게는 연료가스의 종류나 유량 또는 유속이 변하더라도 파일럿 버너를 교체하거나 변형하지 않고 사용할 수 있도록 하는 깔때기형 점화기가 설치된 파일럿 버너에 관한 것이다.The present invention relates to an ignitor of a pilot burner, and more particularly, to a pilot burner equipped with a funnel type igniter that can be used without replacing or modifying the pilot burner even if the type, flow rate or flow rate of fuel gas changes. will be.

도 1a 및 도 1b는 종래의 파일럿 버너에 점화기가 설치된 상태를 나타내는 개략적 설명도이다.1A and 1B are schematic explanatory diagrams showing a state where an igniter is installed in a conventional pilot burner.

종래의 파일럿 버너는 도 1a에 나타낸 바와 같이, 연료가스(연료와 공기의 혼합가스)를 공급하는 버너 팁(1)의 외부에 착화용의 점화기(2)를 위치시켜 스파크에 의한 착화를 유도하거나, 도 1b에 나타낸 바와 같이, 연료가스를 유입하는 버너 팁(1)의 내부에 점화기(2)를 위치시켜 이 버너 팁(1)과 점화기(2)의 최근접점에서 착화가 이루어 지도록 구성되어 있다.In the conventional pilot burner, as shown in FIG. 1A, the igniter 2 for ignition is placed outside the burner tip 1 for supplying fuel gas (mixed gas of fuel and air) to induce ignition by sparking or As shown in FIG. 1B, the igniter 2 is positioned inside the burner tip 1 through which fuel gas is introduced, so that ignition occurs at the closest contact point between the burner tip 1 and the igniter 2. .

이와 같이 구성된 파일럿 버너는 버너 팁(1) 내부를 통하여 연료가스를 공급하면서 점화기(2)에 고압전류를 부여하면, 상기 버너 팁(1)과 점화기(2)의 최근접점에서 스파크가 발생되고, 이 스파크에 의해 흐르는 연료가스도 연소되면서 점화된다.In the pilot burner configured as described above, when high pressure current is applied to the igniter 2 while supplying fuel gas through the inside of the burner tip 1, spark is generated at the closest contact point between the burner tip 1 and the igniter 2. The fuel gas flowing by the spark is also ignited while burning.

그러나, 이와 같은 점화기(2)의 설치구성에 따르면, 연료가스의 유량 또는 유속이 변하거나, 연료가스의 종류가 바뀔 경우(COG 에서 LPG)에 점화기(2)의 스파크 작용에 의해 발생되는 화염의 안정성이 떨어지고, 화염의 부상(lifting)이나 역화(flashback)의 위험이 존재하는 문제점이 있었다.However, according to such an installation structure of the igniter 2, when the flow rate or flow rate of fuel gas changes, or the kind of fuel gas changes (COG to LPG), the flame which is generated by the spark action of the igniter 2 changes. There is a problem that the stability is lowered, there is a risk of lifting or flashback of the flame.

본 고안은 상기와 같은 종래의 문제점을 해소하고자 고안된 것으로, 화염의 부상이나 역화의 위험성을 배제하고 화염에 대한 보호기능(보염기능)을 강화할 수 있도록 버너 팁의 내부에 깔때기 형상의 점화기를 설치한 깔때기형 점화기가 설치된 파일럿 버너를 제공함을 그 목적으로 한다.The present invention is designed to solve the conventional problems as described above, by installing a funnel-shaped igniter inside the burner tip to eliminate the risk of injury or backfire of the flame and to strengthen the protection function (flame protection) against the flame It is an object to provide a pilot burner equipped with a funnel igniter.

상기의 목적을 달성하기 위한 본 고안은, 끝부분을 깔때기 형상으로 형성한 깔때기형 점화기(10)를 버너 팁(1)의 내부에 제1절연지지체(11) 및 제2절연지지체(12)로 지지하여 설치하고, 상기 제2절연지지체(12)의 설치면적을 조절할 수 있도록 함을 특징으로 한다.The present invention for achieving the above object, the funnel-type igniter 10 formed in the funnel shape of the end to the first insulating support 11 and the second insulating support 12 in the burner tip (1) It supports and installs, it characterized in that to adjust the installation area of the second insulating support (12).

이하, 첨부 도면을 참조하여 본 고안 깔때기형 점화기가 설치된 파일럿 버너에 대하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the pilot burner provided with the present invention funnel type igniter.

도 2는 본 고안에 따른 깔때기형 점화기가 설치된 파일럿 버너를 나타내는 분해사시도이고, 도 3은 결합상태를 나타내는 측단면도이다.Figure 2 is an exploded perspective view showing a pilot burner installed with a funnel igniter according to the present invention, Figure 3 is a side cross-sectional view showing a coupling state.

본 고안은 파일럿 버너의 보염기능과 안정적인 착화의 기능을 동시에 달성할 수 있는 것으로, 파일럿 버너의 버너 팁(1)의 내부에 끼워지는 깔때기형 점화기(10)와, 이 깔때기형 점화기(10)를 상기 버너 팁(1)에 고정시켜 줌과 동시에 통과되는 연료가스의 유량 및 유속을 제어할 수 있는 제1 및 제2절연지지체(11)(12)로 구성된다.The present invention is to achieve the function of the flame burner and the stable ignition of the pilot burner at the same time, the funnel-type igniter (10) fitted to the inside of the burner tip (1) of the pilot burner, and the funnel-type igniter (10) The first and second insulating supports 11 and 12 are fixed to the burner tip 1 and control the flow rate and the flow rate of the fuel gas to pass through.

상기 깔때기형 점화기(10)는 종래의 점화기의 선단부분을 깔때기 형상으로 변형시킨 것으로, 그 끝단부분은 원통형의 버너 팁(1)에 끼워질 수 있도록 이 버너 팁(1)에 평행하게 원통형으로 되어 있다.The funnel-type igniter 10 is a front end portion of the conventional igniter deformed into a funnel shape, the end portion of which is cylindrical in parallel to the burner tip 1 so as to be fitted to the cylindrical burner tip 1. have.

한편, 상기 깔때기형 점화기(10)를 버너 팁(1)의 내부에 고정시키기 위하여 다수개의 제1절연지지체(11)가 설치된다. 이 제1절연지지체(11)는 버너 팁(1)의 내주면과 밀착되는 원통형상으로, 상기 깔때기형 점화기(10)가 끼워지기 위한 구멍 및 연료가스가 통과할 수 있는 다수개의 연료가스구멍(13)이 형성되어 있다. 상기 연료가스구멍(13)은 이를 통과하는 연료가스의 양에 알맞게 형성되어 있으면 되고, 그 형상이나 개수에는 특별한 제한이 없다.Meanwhile, a plurality of first insulating supports 11 are installed to fix the funnel type igniter 10 to the inside of the burner tip 1. The first insulating support 11 has a cylindrical shape in close contact with the inner circumferential surface of the burner tip 1, and includes a hole through which the funnel type igniter 10 is fitted and a plurality of fuel gas holes 13 through which fuel gas can pass. ) Is formed. The fuel gas hole 13 may be formed so as to be suitable for the amount of fuel gas passing therethrough, and the shape and number of the fuel gas holes 13 are not particularly limited.

또한, 상기 버너 팁(1)과 깔때기형 점화기(10)의 끝단부분의 사이에는 다수개의 제2절연지지체(12)가 빈 공간을 형성하면서 설치된다. 이 빈 공간으로 연료가스가 공급되고 그 끝단부에서 착화가 일어나게 되기 때문에, 빈 공간의 크기에 따라 연료가스의 유입량을 변경할 수 있다.In addition, a plurality of second insulating supports 12 are installed between the burner tip 1 and the end of the funnel type igniter 10 to form an empty space. Since fuel gas is supplied to this empty space and ignition occurs at the end thereof, the flow rate of fuel gas can be changed according to the size of the empty space.

도 4a 및 도 4b는 각각 연료가스의 유량이 많이 필요한 경우 및 적게 필요한 경우에 상기 제2절연지지체(12)의 설치면적을 나타내는 정면도이다.4A and 4B are front views showing the installation area of the second insulating support 12 when the flow rate of the fuel gas is large and small, respectively.

여기서, 상기 깔때기형 점화기(10)는 고압의 전류가 흐르게 되므로, 이와 상기 버너 팁(1)을 연결 지지하는 상기 제1 및 제2절연지지체(11)(12)는 절연성이 우수한 재질로 제작되어야 하는 것이다.Here, the funnel-type igniter 10 is a high-current current flows, the first and second insulating support 11, 12 for supporting the burner tip 1 and the connection should be made of a material having excellent insulation. It is.

이와 같이 구성된 본 고안에 따른 깔때기형 점화기가 설치된 파일럿 버너의 작동에 대하여 설명하면 다음과 같다.Referring to the operation of the pilot burner equipped with a funnel igniter according to the present invention configured as described as follows.

착화를 위해서 상기 깔때기형 점화기(10)에 고압전류를 흘리면, 상기 깔때기형 점화기(10)와 버너 팁(1)의 최근접점에서 스파크가 발생하고, 이 스파크에 의해 연료가스가 연소되면서 파일럿 버너가 점화된다.When a high voltage is applied to the funnel type igniter 10 for ignition, sparks are generated at the closest contact point of the funnel type igniter 10 and the burner tip 1, and the fuel gas is combusted by the sparks, thereby causing the pilot burner to burn. Ignite

이때 상기 제2절연지지체(12)의 설치 개수 및 크기를 연료의 종류 및 유속 또는 유량 등의 변화에 따라 적절하게 조절하면 안정적인 착화가 가능하게 된다.At this time, if the number and size of the installation of the second insulating support 12 is appropriately adjusted according to the change of fuel type and flow rate or flow rate, stable ignition is possible.

더욱이 본 고안의 깔때기형 점화기(10)는 끝부분에서 이 깔때기형 점화기(10)의 내측방향쪽으로 연료가스의 흐름을 유도하여 주기 때문에 발생된 화염을 지지보호해주는 보염(flame holding) 기능을 동시에 수행할 수 있다.Furthermore, the funnel type igniter 10 of the present invention simultaneously performs a flame holding function to support and protect the generated flames by inducing the flow of fuel gas toward the inner side of the funnel type igniter 10 at the end. can do.

이상에서 설명한 바와 같이 본 고안 깔때기형 점화기가 설치된 파일럿 버너를 사용하면, 연소가스의 종류나 유량 및 유속의 변경에 적절히 대응하여 안정적인 착화를 유도할 수 있을 뿐만 아니라, 보염기능을 동시에 수행할 수 있는 효과가 있다.As described above, using the pilot burner provided with the present invention funnel type igniter, it is possible not only to induce stable ignition by appropriately responding to changes in the type, flow rate and flow rate of the combustion gas, but also to perform the flame protection function at the same time. It works.
