본 고안은 등유와 같은 액체연료의 기화식 버너에 관한 것이다.The present invention relates to a vaporized burner of a liquid fuel such as kerosene.
종래, 제1도에서 보는 바와같이 액체연료(a)를 기화기본체(10)의 안쪽에 배치한 확산체(20)에 의하여 회전 분무화되고, 더욱이 이 기화기본체(10)로 기화시켜, 이것과 송풍팬(30)으로 기화기본체(10)로 송풍된 연소용 공기와 혼합해서 버너체(40)의 연소공(41a)이 있는 주벽 (41)에서 착화연소시키는 액체연료 기화식 버너에 있어서, 상기 기화기본체(10)의 상부에 있는 열회수플랜지(11)를 버너체(40)의 열화수플랜지(11)를 버너체(40)의 주벽(41)의 하단을 포위하여 형성한 액체연료 기화식 버너가 알려져 있다.Conventionally, as shown in FIG. 1, the liquid fuel a is rotated and sprayed by the diffuser 20 disposed inside the vaporization base 10, and further vaporized into the vaporization base 10, and In the liquid fuel vaporization type burner which mixes with the combustion air blown into the vaporization main body 10 by the blowing fan 30, and ignites and burns in the circumferential wall 41 which has the combustion hole 41a of the burner body 40, The said A liquid fuel vaporization burner in which the heat recovery flange 11 on the upper part of the vaporization base body 10 is formed by surrounding the lower end of the circumferential wall 41 of the burner body 40 with the deteriorated water flange 11 of the burner body 40. Is known.
그러나, 이와같은 액체연료 기화식 버너에서는, 기화기 본체(10)의 열화수플랜지(11)가 버너체(40)의 주벽(41)으로부터 분출하는 연소화염(B)의 연소열을 충분히 홉수할 수 없고, 특히 연소량이 클때에는 액체연료(A)의 산포량 및 공기의 송풍량이 많아지기때문에 그 온도가 대폭 저하한다는 결점이 있었다.However, in such a liquid fuel vaporization burner, the deteriorated water flange 11 of the vaporizer body 10 cannot sufficiently pass the heat of combustion of the combustion flame B ejected from the circumferential wall 41 of the burner body 40 sufficiently. In particular, when the combustion amount is large, the dispersion amount of the liquid fuel (A) and the air blowing amount of air increase, so that the temperature decreases significantly.
또한 이와같은 결점을 막기 위하여 기화기본체(10)의 하부에 부착되어 있는 히터(60)를 점화시킨다는 방법이 사용되고 있으나 이 방법으로는 에너지 절약상 문제가 있다.In addition, in order to prevent such drawbacks, a method of igniting the heater 60 attached to the lower part of the vaporization main body 10 is used, but this method has a problem in energy saving.
본 고안은 상기한 바와같은 종래의 결점을 감안하여, 버너체의 주벽으로부터 분출하는 연소화염의 연소열을 충분히 흡수하는 기화기본체를 구비한 액체연료 기화기 버너를 제공하는 것을 목적으로 하고 있다.The present invention aims at providing a liquid fuel vaporizer burner provided with a vaporization base body which sufficiently absorbs the combustion heat of a combustion flame ejected from the main wall of the burner body in view of the above-described conventional drawbacks.
이하, 본 고안을 도면에 의하여 설명한다.Hereinafter, the present invention will be described with reference to the drawings.
제2도 및 제3도는 본 고안의 1실시예를 보여주는 것으로, 종래의 예와 동일한 구성부분은 동일부호로 사용한다.2 and 3 show an embodiment of the present invention, the same components as in the conventional example are denoted by the same reference numerals.
즉, 도면에서 부호 20은, 확산날개(21), 보온판(22), 다리(23) 및 액체연료 공급통(24)으로 구성되는 확산체로서, 상기 다리(23)에 의하여 보온판(22)과 연료공급통(24)과의 사이에 소정간격(25)이 형성되고 있다.That is, in the drawing, reference numeral 20 denotes a diffuser composed of the diffusion wing 21, the heat insulating plate 22, the leg 23, and the liquid fuel supply cylinder 24, and the heat insulating plate 22 is formed by the leg 23. ) And a predetermined interval 25 is formed between the fuel supply cylinder 24.
부호 30은 공기덕트(31)의 안쪽에 배치된 송풍팬이며 송풍용 로우터(32)의 회전축(32a)의 한끝에 부착되어 있다.Reference numeral 30 denotes a blowing fan arranged inside the air duct 31 and attached to one end of the rotation shaft 32a of the blowing rotor 32.
부호 40은 모자형으로 형성된 버너체이며, 그의 주벽(41)에 다수의 연소공(41a)을 갖고 있다.Reference numeral 40 is a burner body formed in a hat shape, and has a plurality of combustion holes 41a in its circumferential wall 41.
부호 50은 공기송풍통이며, 후술하는 기화기본체(70)의 바깥쪽에 소정간격을 두고 부착되었으며, 그의 주벽(51)에는 복수의 송풍공(51a)이 있고, 기화기본체(70)를 강제공냉하는 작용을 한다.Reference numeral 50 denotes an air blower, which is attached to the outer side of the vaporizing base body 70 to be described later with a predetermined interval, and the main wall 51 has a plurality of blow holes 51a, for forced air cooling of the vaporizing base body 70. It works.
부호 60은 기화기본체(70)의 하부에 부착된 히터이다.Reference numeral 60 denotes a heater attached to the lower part of the vaporizing base 70.
부호 70은 전열성 및 내열성을 가지고 있는 재료로 구성된 기화기본체로서, 대직경의 상부원통(열회수플랜지)(70a)과 소직경의 하부원통(기화부)(70b)을 연결함으로써 이루어진 것이며, 열회수플랜지(70a)는 상기 버너체(40)와 공기송풍통(50)과의 사이에 소정간격을 두고 위치하고 있으며, 또한, 이 버너체(40)의 주벽(41)을 포위하도록 상방으로 연결하여 이루어진다.Reference numeral 70 denotes a vaporization base composed of a material having heat transfer and heat resistance, and is formed by connecting a large diameter upper cylinder (heat recovery flange) 70a and a small diameter lower cylinder (vaporization portion) 70b, and a heat recovery flange. The 70a is positioned at a predetermined interval between the burner body 40 and the air blower 50, and is connected upwards to surround the circumferential wall 41 of the burner body 40. As shown in FIG.
그리고, 부호 80은 상기 확산체(20)에 회전축(80a)을 연결한 모우터, 90은 전자펌프, 100은 일단을 전자펌프(90)에 연결하고, 타단을 화산체(20)의 연료공급통(24) 내측에 배치한 연료공급관 110은 서미스터, 120은 점화봉, 130은 화염검지기이다.And, the reference numeral 80 is a motor connecting the rotary shaft 80a to the diffuser 20, 90 is an electronic pump, 100 is connected to one end of the electron pump 90, the other end of the fuel supply tank of the volcanic body 20 (24) The fuel supply pipe 110 disposed inside is a thermistor, 120 is an ignition rod, and 130 is a flame detector.
전술한 바와같은 구성에 있어서, 액체연료 기화식 버너에 점화조작을 하면, 전자펌프(90)에 의하여 연료공급통(24)의 안쪽으로 분출된 액체연료(A)는 확산체(20)의 회전에 따른 원심력에 의해 이 연료공급통(24)의 내벽면을 상승하여 간격(25)으로부터 기화기본체(70)의 기화부(70b)를 향하여 분무상태로 비산한다.In the above-described configuration, when the ignition operation is performed on the liquid fuel vaporization burner, the liquid fuel A ejected into the fuel supply container 24 by the electronic pump 90 rotates the diffuser 20. The inner wall surface of this fuel supply container 24 is raised by the centrifugal force, and it scatters in the spray state toward the vaporization part 70b of the vaporization base body 70 from the space | interval 25.
기화부(70b)는 히터(60)로 기화온도까지 가열되고 있기때문에, 기화면에 닿는 분무상의 액체연료(A)는 순간적으로 기화된다.Since the vaporization part 70b is heated to the vaporization temperature by the heater 60, the spray liquid liquid A which touches a vapor screen is vaporized instantly.
이 기화된 액체연료(A)는 송풍팬(30)에 의하여 강제적으로 공기덕트(31)의 송풍공(31a) 및 모우터(80)의 부착판(81)의 관통공(81a)을 통하여 유입한 공기와 혼합되어 연소개스로 된다. 이 연소개스는 혼합통(140)을 통하여 버너체(40)로 유입하고 다시 균압통(150) 및 금망(160)을 통하여 버너체(40)의 주벽(41)의 연소공(41a)으로부터 방출되며, 점화봉(120)의 불꽃으로 점화해서 기화기 본체(70)의 열회수플랜지(70a)로 향하여 연소화염(B)이 분출한다.The vaporized liquid fuel (A) is forcibly introduced by the blowing fan 30 through the blowing hole 31a of the air duct 31 and the through hole 81a of the attachment plate 81 of the motor 80. It is mixed with air to form a combustion gas. This combustion gas flows into the burner body 40 through the mixing cylinder 140, and is discharged from the combustion hole 41a of the circumferential wall 41 of the burner body 40 through the pressure equalizing cylinder 150 and the gold screen 160 again. The combustion flame B is ejected toward the heat recovery flange 70a of the vaporizer body 70 by igniting with the spark of the ignition rod 120.
그리하여, 이 연소화염(B)에 의하여 열회수플랜지(70a) 가열되고 기화부(70b)가 기화온도에 달했을 때 히터 (60)의 통전은 정지되고 열회수플랜지(70a)의 흡수열만으로 액체연료(A)의 기화 및 연소가 계속되게 된다.Thus, when the heat recovery flange 70a is heated by this combustion flame B and the vaporization unit 70b reaches the vaporization temperature, the energization of the heater 60 is stopped and the liquid fuel A is only absorbed by the heat of absorption of the heat recovery flange 70a. Evaporation and combustion will continue.
이와같이 기화기본체(70)의 열회수플랜지(70a)는 항상 연소화염(B)에 의하여 충분히 가열되고 기화부(70b)의 온도를 유지한다는 점에서, 제3도에서 보여주는 바와같이 종래의 액체연료 기화식 버너(1점쇄선으로 나타낸(a))와 비교하여 본 고안의 액체연료 기화식버너(실선으로 나타낸(b))는 설혹 연소량이 많을때에도 기화부(70b)의 온도를 이상적인 기화온도(280℃-300℃)에서 급격히 내려가는 일이없다. 이 때문에 연소범위가 넓은 버너를 제공할 수 가 있다.In this way, the heat recovery flange 70a of the vaporization body 70 is always sufficiently heated by the combustion flame B and maintains the temperature of the vaporization part 70b, as shown in FIG. Compared with the burner (a dashed-dotted line (a)), the liquid fuel evaporative burner (solid dashed-line (b)) of the present invention makes the ideal vaporization temperature (280 ° C) even when the combustion amount is large. -300 ℃) does not fall sharply. This can provide a burner with a wide combustion range.
또한, 기화기본체(70)의 열회수플랜지(70b)를 상기 버너체(40)외 주벽(41)을 포위한 것과 같이 형성해서 이루어진 것이므로, 연소화염(B)온 열회수플랜지(70b)에 충돌하여 항시 주벽(41)과 열회수플랜지(70b)와외 사이에 연소화염(B)이 유지되어, 안정연소를 얻을 수 있다.In addition, since the heat recovery flange 70b of the vaporization base body 70 is formed in such a manner as to surround the burner body 40 and the outer circumferential wall 41, the combustion flame (B) is always in contact with the heat recovery flange 70b. The combustion flame B is maintained between the circumferential wall 41 and the heat recovery flange 70b to provide stable combustion.
이상에서 설명한 바와같이 본 고안에 의하면 확산체로 회전분무화하고 또한 열회수플랜지가 있는 통모양의 기화기본체에서 기화된 액체연료와 송풍팬에 의하여 기화기본체에 송풍된 연소용공기와를 혼합시켜 이를 버너체 주벽의 연소공에서 연소시키는 액체연료 기화식 버너에 있어서, 열회수플랜지를 버너체의 주벽으로부터 소정 간격을 두고 주벽을 둘러싼것처럼 형성했으므로, 기화기본체의 열회수플랜지는 항시 연소화염으로 인하여 충분히 가열되어 기화부의 온도를 유지하고, 연소량이 많을때에도 기화부의 온도를 급격히 낮추는 일이 없으며, 항시 안정연소를 얻을 수 있는 잇점이 있다. 또한 버너의 주벽으로부터 분출되는 연소화염은 이 열회수플랜지에 충돌하여 이 주벽과 열회수플랜지와의 사이에서 유지되므로, 안정연소를 얻을 수 있다. 특히, 이 열회수플랜지의 회수열만으로 액체연료의 기화연소를 계속할 수 있으므로 히터에 의하여 기화기본체를 가열할 필요가 없어서 에너지 절약면에서도 유리하다.As described above, according to the present invention, the rotary atomization into the diffuser and the combustion fuel blown into the vaporization base by the blower fan by mixing the vaporized liquid fuel with the heat recovery flange and the burner body In the liquid fuel vaporization burner which burns in the combustion hole of the main wall, since the heat recovery flange is formed as surrounding the main wall at a predetermined distance from the main wall of the burner body, the heat recovery flange of the vaporization base body is always sufficiently heated by the combustion flame, so that Even when the temperature is maintained and the combustion amount is large, the temperature of the vaporization portion is not lowered rapidly, and there is an advantage that stable combustion can be obtained at all times. In addition, the combustion flame ejected from the burner's circumferential wall collides with the heat recovery flange and is held between the circumferential wall and the heat recovery flange, so that stable combustion can be obtained. In particular, since the vaporization combustion of the liquid fuel can be continued only with the recovery heat of the heat recovery flange, it is not necessary to heat the vaporization base body by the heater, which is advantageous in terms of energy saving.
