본 고안은 등유를 연료로 사용하는 석유팬 히터(Fan Heater)용 기화식 버어너 구조에 관한 것으로, 특히 버어너의 내부 온도변화에 의한 연료의 미립화 부족 현상과 이에 따른 적화 현상(연소시 불꽃이 적색으로 되는 현상)을 방지하여 버어너의 성능을 향상시킬 수 있도록 한 것이다.The present invention relates to a vaporized burner structure for a fan heater using kerosene as a fuel, and in particular, a lack of atomization of fuel due to a change in the internal temperature of the burner, and a corresponding phenomenon of burning (burning during combustion). It is possible to improve burner performance by preventing red phenomenon.
본 고안이 적용되는 석유팬히터는 제1도와 같이 연료탱크(5), 연료 받이탱크(6), 송유관(7), 전자펌프(8), 정유면기(9), 분사노즐(4) 등으로 이루어진 연료공급라인과 연소용 송풍기(10), 송풍경로(11), 냉각튜우브(12), 가압튜우브(13)등으로 이루어진 연소용 공기공급 라인 그리고 기화통(1), 온도검지서미스터(14), 열검지기(15), 전기히터(16), 점화플러그(17) 등으로 된 버어너부로 구성되어 밌으며, 낙차식 연료탱크(5)내의 연료(등유)가 송유관(7)을 통해 전자펌프(8)의 입구까지 도달한 상태에서 운전스위치를 작동시키면 기화통(1) 내부에 있는 예열용 전기히터(16)에 통전되어 기화통(1) 전체가 가열되고, 전기히터(16)의 가열에 의해 기화통(1)의 내부 온도가 약 240°씨에 이르게 되면 온도검지서미스터(14)가 이를 감지하여 전자펌프(8)와 연소용 송풍기(10)를 작동시키도록 되어 있다.Petroleum fan heater to which the present invention is applied is composed of a fuel tank (5), a fuel receiving tank (6), an oil supply pipe (7), an electronic pump (8), an oil level machine (9), an injection nozzle (4) as shown in FIG. Combustion air supply line consisting of a fuel supply line, a combustion blower 10, a blowing path 11, a cooling tube 12, and a pressurized tube 13, a vaporization cylinder 1, and a temperature detecting thermistor ( 14), the burner part which consists of the heat detector 15, the electric heater 16, the spark plug 17, etc. is interesting, and the fuel (kerosene) in the drop-off fuel tank 5 passes through the oil pipe 7 When the operation switch is operated while reaching the inlet of the electromagnetic pump 8, the preheating electric heater 16 inside the vaporization cylinder 1 is energized to heat the entire vaporization cylinder 1, and the electric heater 16 is operated. When the internal temperature of the vaporization container 1 reaches about 240 ° C by heating, the temperature detecting thermistor 14 detects this to operate the electronic pump 8 and the combustion blower 10. It is supposed to be.
그리고 전자펌프(8)와 연소용 송풍기(10)가 작동하여 수초(약 16초 정도)가 경과하면 점화플러그(17)와 가압솔레노이드(18)가 통전되어 밸브가 열리게 되고 이에 따라 송풍경로(11)와 가압튜우브(13)를 통해 정유면기(9)로 유입된 공기에 의해 정유면기(9)의 내부압력이 높아져 정유면기(9)로 유입된 연료가 파이프 오리피스(19)와 노즐(4)을 통해 공기흡입구에서 공기와 혼합되면서 기화통(1)으로 분사하게 되는데, 이때에는 기화통(1)의 내부가 이미 가열된 상태에 있고 점화플러그(17)에는 전류가 통전되어 방전이 이루어지고 있는 상태에 있으므로 분사되는 연료는 즉시 기화됨과 동시에 점화플러그(17)에 의해 착화되어 연소하게 되어 있다.When the electronic pump 8 and the combustion blower 10 are operated for a few seconds (about 16 seconds), the ignition plug 17 and the pressurized solenoid 18 are energized to open the valve. 11) and the internal pressure of the oil level machine 9 is increased by the air introduced into the oil level machine 9 through the pressure tube 13, and the fuel introduced into the oil level machine 9 is connected to the pipe orifice 19 and the nozzle ( 4) is injected into the vaporization cylinder (1) while being mixed with the air at the air inlet through this, in which case the interior of the vaporization cylinder (1) is already heated and the spark plug (17) is energized to discharge the current Since it is in the losing state, the injected fuel is vaporized immediately and ignited by the spark plug 17 to burn.
따라서 이러한 구조를 가진 석유팬 히터에 있어서는 분사되는 연료가 작은 입자상태로 기화되어야 하고 분사시 공기와의 혼합작용이 원활히 이루어져야 양호한 연소가 가능해지며, 기화작용이 양호하게 이루어지기 때문에 기화통(1) 내부의 온도가 항상 적정온도(약 240°씨)로 유지되어야 하고 공기와의 원활한 혼합을 위해서는 노즐의 분사각도가 커지는 것이 바람직하다.Therefore, in the petroleum fan heater having such a structure, the fuel to be injected must be vaporized in a small particle state, and when the injection is carried out smoothly with the air, a good combustion is possible, and the vaporization can be performed well. The internal temperature should always be maintained at an appropriate temperature (about 240 ° C) and it is desirable that the nozzle spray angle is increased for smooth mixing with air.
그러나 석유팬 히터에 사용되어온 종래의 버어너는 제5도 및 제6도에 도시한 바와 같이 노즐(4)의 끝부분에 45°정도의 경사면만이 형성되어 있어 연료의 분사각도가 작고 이에 따라 공기흡입구로 흡입되는 연소공기와의 혼합이 충분하지 못하며, 또한 기와통(1)의 내부가 단순한 평면상으로 되어 적정온도의 유지가 어렵기 때문에 기화통(1) 내부의 온도가 적정온도보다 낮거나 높아지는 경우가 많고 이러한 경우 기화된 등유의 입자가 커져 적화연소나 불완전연소의 원인이 되었다.However, in the conventional burner used for petroleum fan heater, as shown in FIGS. 5 and 6, only the inclined surface of about 45 ° is formed at the end of the nozzle 4, so that the injection angle of the fuel is small. Since the mixing with the combustion air sucked into the air inlet is not sufficient, and the inside of the gas cylinder 1 becomes a simple plane, it is difficult to maintain the proper temperature, so the temperature inside the gas cylinder 1 is lower than the proper temperature. In many cases, the vaporized kerosene particles increase, which causes reddening and incomplete combustion.
본 고안은 종래의 이와같은 문제점을 해결하기 위해 기화통 내부의 가열면적을 크게하고 노즐의 분사각도를 크게하여 버어나가 항상 양호한 연소상태를 유지할 수 있도록 한것인바, 이를 첨부된 도면 제2도 내지 제4도에 의해 더욱 상세히 설명하면 다음과 같다.The present invention is to solve the problems of the prior art to increase the heating area inside the gas cylinder and to increase the spray angle of the nozzle so that it can always be maintained in a good combustion state, it is attached to Figure 2 4 to be described in more detail as follows.
기화통(1)의 내부 바닥면에 다수의 돌기(2)를 형성함과 함께 내부 전체면에 흑색 내열도장을 하여 복사층(3)을 형성하고 노즐(4)의 끝부분에는 측면으로 파여진 요입홈(4a)과 경사면(4b)을 형성하여서 된 것이다.Forming a plurality of projections (2) on the inner bottom surface of the vaporization container (1) and by applying a black heat-resistant coating on the entire inner surface to form a radiation layer (3) and the end of the nozzle 4 is dug into the side It is made by forming the recessed groove 4a and the inclined surface 4b.
이와같이 구성된 본 고안은 기화통(1) 내부 바닥면에 형성된 돌기(2)에 의해 기화통(1)의 가열면적이 커져 기화통(1) 내부의 온도가 적정온도 이하로 낮아지는 경우가 거의 없게 되고, 기화통(1) 내부의 온도가 적정온도 이상으로 다소 높아지는 경우에도 제4도와 같이 기화통(1) 내부 전체에 걸쳐 도장된 복사층(3)의 복사효과에 의해 등유의 입자크기는 작아지게 되므로 분사되는 연료를 항상 작은 입자 상태로 기화시킬 수 있게 된다.According to the present invention configured as described above, the heating area of the vaporization cylinder 1 is increased by the projections 2 formed on the bottom surface of the vaporization cylinder 1 so that the temperature inside the vaporization cylinder 1 is not lowered to an appropriate temperature or less. The particle size of kerosene is small due to the radiation effect of the radiation layer 3 coated over the entire interior of the vaporization cylinder 1 as shown in FIG. 4 even when the temperature inside the vaporization cylinder 1 becomes slightly higher than the appropriate temperature. As a result, the injected fuel can always be vaporized into a small particle state.
또한 노즐(4)의 끝부분에 요입홈(4a)과 경사면(4b)에 의해 연료의 분사각도가 커지게 되어 연소용공기와의 혼합작용이 양호해지고 이에따라 적화연소나 불완전연소가 발생하지 않게 되므로 연소효율이 향상되고 연료를 절감할 수 있는 효과가 있다.In addition, the injection angle of the fuel is increased by the concave groove 4a and the inclined surface 4b at the end of the nozzle 4, so that the mixing action with the combustion air is good, and thus, redox or incomplete combustion does not occur. Improve combustion efficiency and save fuel.
