Description
본 발명은 경유나 등유 등을 주연료로 사용하는 버너에 관한 것으로, 송풍되는 공기가 와류현상을 일으켜 회오리치면서 유속이 증가되 분사되는 연료를 완전연소 시킴으로써 고열이 방출되는 한편 연료를 절약하고 배기가스를 줄이는 연료절 약형 버너에 관한 것이다.The present invention relates to a burner that uses light oil or kerosene as the main fuel, and the blown air causes vortex vortex to increase the flow rate while completely burning the injected fuel, thereby saving fuel and exhaust gas. To reduce fuel It is about a weak burner.
경유와 등유가 주연료인 기름버너는 일반적으로 송풍장치를 설치해서 강한 송풍력으로 공기를 강제 유입시키고 연료를 미립자로 분사시켜 공기와 혼합되도록 하여 연소시킴으로써 그 발열온도를 이용해 보일러나 산업용노에 사용하고 있다.Oil burners, whose main fuel is light oil and kerosene, are generally used in boilers or industrial furnaces by installing the blower and forcibly introducing air with strong blowing force and injecting the fuel into fine particles to mix with the air to burn. Doing.
이와같은 종래 기름버너의 구조는 도면에 도시한 도 1 과 같이 보일러 몸체의 부착판(1)에 버너슬리브(2)가 장착되고 이 버너슬리브(2) 안에 송풍되는 바람에 의해 고속회전하는 팬(3)이 결합된 연료공급축(4)이 설치된다.Such a conventional oil burner has a burner sleeve 2 mounted on the attachment plate 1 of the boiler body as shown in FIG. 1 and a fan rotating at high speed by wind blown in the burner sleeve 2 ( The fuel supply shaft 4 to which 3) is coupled is installed.
또한 연료공급축(4)의 선단에는 분사노즐(5)이 결합되어 공급되는 연료를 미립자로 분사시켜 연소가 이루어지도록 하며 버너슬리브(2)의 선단 내측에 나팔관 형상의 경사면을 소유한 화염캡(6)이 설치되 공기와 분사되는 연료를 혼합시켜 연소효율을 높이고 있다.In addition, the end of the fuel supply shaft (4) is coupled to the injection nozzle (5) to inject the fuel supplied by the particles to the combustion is carried out and the flame cap having a fallopian tube-shaped inclined surface inside the front end of the burner sleeve (2) 6) is installed to increase combustion efficiency by mixing air and fuel injected.
이러한 종래의 버너는 송풍장치로 공기가 강제 유입되 팬을 고속회전시켜 유입되는 공기압을 높이며 나팔관 형상의 화염캡이 공기의 배출공간을 좁혀 공기압을 더욱 높히고 유속을 증가시켜 분사노즐에서 미립자로 분사되는 연료와 혼합되 연소가 이루어지게 된다.Such a conventional burner is forced into the air blower to increase the air pressure by rotating the fan at high speed and the fallopian tube-shaped flame cap narrows the discharge space of the air to further increase the air pressure and increase the flow rate is injected into the particles from the injection nozzle Combustion is achieved by mixing with the fuel.
따라서 종래의 버너는 송풍장치에 의해 공기압의 상승이 한정되고 유입되는 공기가 화염캡에 의해 유속이 빠른상태로 버너슬리브를 통과하게 되므로 미립자로 분사되는 연료와 적정한 비율로 혼합되지 못해 불완전연소를 초래해 매연을 유발시키며 연료의 소모량이 높아지게 된다.Therefore, in the conventional burner, the increase in air pressure is limited by the blower, and the inflowing air passes through the burner sleeve at a high flow rate by the flame cap, so that it cannot be mixed with the fuel injected as fine particles at an appropriate ratio, resulting in incomplete combustion. It causes soot and increases fuel consumption.
또한 불완전연소로 인해 연료의 소모량만 증가할뿐 발열온도를 높게 유지시 키지 못해 산업용도로 사용할 때 제품의 품질을 떨어트리게 되며 보일러의 수명을 단축시키는 원인을 초래한다.In addition, due to incomplete combustion, only the fuel consumption increases, It is not tall enough to reduce the quality of the product when used for industrial purposes and causes the life of the boiler.
본 발명은 유입되는 공기의 유속을 높히고 와류현상을 일으켜 유입되는 공기가 회오리치도록 하여 분사되는 연료와 혼합비를 높혀서 연료를 완전연소시키기 위한 것이다.The present invention is to completely burn the fuel by increasing the flow rate of the incoming air and causing the vortex phenomenon to swirl the incoming air to increase the mixing ratio with the injected fuel.
이러한 본 발명은 버너슬리브 안에 고속회전하는 팬이 장착되고 선단에 분사노즐이 결합된 연료공급축이 설치되는 버너를 구성함에 있어서,In the present invention, in the burner sleeve, a fan that rotates at a high speed is mounted, and a burner having a fuel supply shaft coupled to an injection nozzle is installed at the tip.
60~120˚범위로 경사져 원뿔형상을 갖도록 형성되 연료공급축의 선단에 장착되는 화염구와, 상기 화염구의 외부를 감싸도록 버너슬리브의 선단에 결합되며 내측에 라운드진 다수개의 와류날개가 나선형으로 형성되고 80~140˚범위로 경사져 원뿔형상을 갖도록 형성되는 화염캡으로 구성되는 것을 특징으로 하는 것이다.It is formed to have a conical shape inclined in the range of 60 ~ 120˚, the fireball is mounted to the tip of the fuel supply shaft, and coupled to the tip of the burner sleeve to surround the outside of the fireball, a plurality of vortex wings round the inside is formed spirally 80 It is characterized by consisting of a flame cap formed to have a conical shape inclined to ~ 140 ° range.

본 발명은 송풍장치에 의해 공급되는 공기의 유속을 높히고 와류현상을 일으켜 회오리치도록 하여 분사노즐에서 미립자로 분사되는 연료의 혼합비를 높혀 완전연소시키는 것으로, 그 구성은 도면에 도시한 도 2 내지 도 5 에서 자세히 알 수 있다.The present invention is to increase the flow rate of the air supplied by the blower and to cause the vortex phenomenon to swirl to increase the mixing ratio of the fuel injected into the fine particles in the injection nozzle, the configuration is completely burned, the configuration is shown in Figs. See 5 for more details.
경유나 등유 등의 기름이 공급되는 연료공급축(4)이 내장된 버너슬리브(2)는 종래의 버너와 같이 보일러 몸체의 부착판(1)에 고정되며 연료공급축(4)에는 송풍장치에 의해 강제 유입되는 공기 바람으로 고속회전하는 팬(3)이 장착된다.The burner sleeve 2 having the fuel supply shaft 4 to which oil such as diesel oil or kerosene is supplied is fixed to the attachment plate 1 of the boiler body like a conventional burner, and to the fuel supply shaft 4 by a blower. The fan (3) is rotated at a high speed by the air wind forced to flow by.
상기 연료공급축(4)의 선단에는 공급되는 연료를 미립자로 분사시키는 분사노즐(5)이 결합되며 이 분사노즐(5)에 근접하도록 원뿔형상의 화염구(10)가 연료공급축(4)에 장착되는데, 화염구(10)는 유입되는 공기가 저항을 받아 유속이 증가되도록 공기의 송풍방향으로 외경이 점점 작아지게 원뿔형상으로 형성된다.An injection nozzle 5 for injecting the supplied fuel into fine particles is coupled to the tip of the fuel supply shaft 4, and a cone-shaped flame port 10 is provided on the fuel supply shaft 4 so as to be close to the injection nozzle 5. It is mounted, the flame opening 10 is formed in a conical shape so that the outer diameter is gradually reduced in the blowing direction of the air so that the flow rate is increased to receive the incoming air resistance.
화염구(10)는 보일러의 용량에 따라 외경의 크기가 달아질 수 있으나, 대략 60~120˚(A)범위로 경사져 원뿔형상을 갖도록 형성되는데 송풍장치나 보일러의 구조에 따라 적합한 경사를 갖도록 하며 70~90˚가량의 경사각이 공기의 유속을 증가시키기에 이상적이다.The flame opening 10 may have an outer diameter depending on the capacity of the boiler, but is inclined in a range of about 60 to 120 ° (A) to have a conical shape. An inclination angle of about 70-90 ° is ideal for increasing the air flow rate.
또한 화염구(10)에는 공기의 송풍방향으로 관통된 다수개의 통기공(11)이 형성되 유입되는 공기를 분산시켜 연료와 공기의 혼합비를 높이게 된다.In addition, the flame port 10 is formed with a plurality of vent holes 11 penetrated in the air blowing direction to increase the mixing ratio of fuel and air by dispersing the incoming air.
보일러 몸체의 부착판(1)에 고정된 버너슬리브(2)의 선단에는 연료공급축(4)에 장착된 화염구(10)를 감싸도록 화염캡(20)이 설치되는데 화염구(10)와 적당한 틈이 유지되고 유입되는 공기가 분출되게 관통홀(22)이 구비되며 화염구(10)와 틈이 주어져 접하는 내측에 다수개의 와류날개(21)가 나선형으로 부착된다.The flame cap 20 is installed at the tip of the burner sleeve 2 fixed to the attachment plate 1 of the boiler body to surround the flame port 10 mounted on the fuel supply shaft 4. The through hole 22 is provided to maintain a proper gap and the air flowing in is ejected, and a plurality of vortex vanes 21 are spirally attached to the inner side of the flame hole 10 to be in contact with the gap.
상기 화염캡(20)은 버너슬리브(2)의 선단에 분리가능케 체결볼트로 부착되며 화염구(10)와 같이 공기의 송풍방향으로 외경이 점점 작아지는 원뿔형상으로 형성되 화염구(10)를 감싸며 80~140˚(B)범위로 경사져 원뿔형상을 갖도록 구성되는 것이 적합하다.The flame cap 20 is attached to the distal end of the burner sleeve (2) with a fastening bolt detachably and formed in a conical shape that gradually decreases the outer diameter in the air blowing direction, such as the flame opening (10) wraps around the flame opening (10) It is suitable to be configured to have a conical shape inclined in the range of 80 ~ 140˚ (B).
화염캡(20)의 경사각은 화염구(10)의 경사각에 따라 적합한 각을 갖도록 하 여 유입되는 공기가 저항을 받아 유속이 급격하게 높아지는 가운데 관통홀(22)을 통하여 원활히 분출되게 한다.The inclination angle of the flame cap 20 is to have a suitable angle according to the inclination angle of the flame opening (10) The incoming air is resisted to flow smoothly through the through hole 22 while the flow rate is rapidly increased.
화염캡(20)의 내측에 나선형으로 부착되는 와류날개(21)는 도면에 도시된 도 5 와 같이 라운드지게 형성되며 화염캡(20)의 내측면에서 안쪽으로 돌출되게 형성되거나 별도로 융착 부착되어 강제 유입되는 공기를 안내해 분출되는 공기가 와류현상을 일으켜 회오리치게 한다.Spiral wing 21 is spirally attached to the inner side of the flame cap 20 is formed to be round as shown in Figure 5 shown in the figure and protrude inward from the inner surface of the flame cap 20 or separately fused and forced The incoming air is guided, causing the blown air to vortex in a vortex.
이와같은 본 발명은 송풍장치에 의해 버너슬리브(2)로 공기가 강제 유입되 팬(3)이 고속회전 하여 공기압을 높혀 유속이 증가된 가운데 화염구(10)와 화염캡(20)에 의해 배출공간이 좁아져 유입되는 공기가 저항을 받아 공기압이 높아져 유속이 더욱 증가되며 곡선진 와류날개(21)가 배출되는 공기를 나선지게 안내하여 관통홀(22)로 분출되는 공기가 회오리키게 되는 것이다.In the present invention, the air is forced into the burner sleeve 2 by the blower, and the fan 3 rotates at a high speed to increase the air pressure and discharged by the flame port 10 and the flame cap 20 while increasing the flow rate. As the space is narrowed, the inflow air is resisted and the air pressure is increased to further increase the flow velocity, and the air ejected into the through hole 22 is spiraled to guide the air discharged from the curved vortex wing 21 to spiral.
따라서 관통홀(22)로 분출되는 공기가 와류현상으로 인해 회오리치므로써 분사노즐에서 미립자로 분사되는 공기와의 혼합비가 높아져 연소효율을 높이게 되는 것이다.Therefore, the air blown through the through-hole 22 is swirled by the vortex phenomenon, so that the mixing ratio with the air injected as fine particles in the injection nozzle is increased, thereby increasing the combustion efficiency.
본 발명은 송풍장치에 의해 공급되는 공기압을 높혀 유속을 증가시키는 한편 분출되는 공기가 와류현상으로 인해 회오리치므로써 미립자로 분사되는 연료와의 혼합비를 높혀서 연료를 완전연소시켜 고열의 발생과 매연을 줄이는 효과를 얻게 되는 것이다.The present invention increases the flow rate by increasing the air pressure supplied by the blower while increasing the mixing ratio with the fuel injected into the fine particles by whirlwind due to the vortex phenomenon to completely burn the fuel to reduce the generation of high heat and smoke Will be effective.
따라서 연료를 절약하고 배기가스로 인한 환경오염을 방지하며 보일러의 수명을 연장하게 된다.This saves fuel, prevents environmental pollution from exhaust gases and extends boiler life.
