Description

버너용 노즐{A burnet nozzle}Burner nozzle {A burnet nozzle}

본 고안은 액체연료를 분사하여 화열을 발생시키는 버너용 노즐의 개량에 관한 것으로, 더욱 상세하게는 노즐의 분사공의 외주에서 고순도의 산소를 직접 공급하여 연소를 촉진시키므로서 완전 연소를 일으켜 고열의 화열을 발생시킬 수 있도록 한 버너용 노즐에 관한 것이다.The present invention relates to an improvement of a burner nozzle that generates heat by injecting liquid fuel, and more particularly, to provide a high-temperature combustion by completely supplying high-purity oxygen directly from the outer periphery of the injection hole of the nozzle to promote combustion. The present invention relates to a burner nozzle capable of generating heat.

일반적으로 버너용 노즐은 버너의 선단 내부에 설치되어 연료를 버너의 송풍 공기와 함께 강하게 분사시키므로서 화열을 발생시키게 되는 것으로 이러한 종래의 노즐은 노즐 자체에서는 연료를 분사하고 공기는 버너에 설치된 송풍기에 의해 동시에 공급하게 되므로 순수하지 못한 공기가 과량으로 공급되어 완전 연소가 이루어지지않게 되고 특히 과량으로 공급되는 공기량 만큼 대기중으로 많은 열량을 방출하게 됨에 따라 열손실이 과다하므로 연료소모량에 비해 열효율이 낮는 등 여러가지의 단점이 있었다.In general, the burner nozzle is installed inside the tip of the burner to generate heat by injecting the fuel strongly with the blowing air of the burner. The conventional nozzle injects fuel from the nozzle itself and the air is supplied to the blower installed in the burner. As it is supplied at the same time, incomplete air is supplied in excess and complete combustion is not achieved. In particular, the heat loss is excessive due to the excessive amount of heat released into the atmosphere as much as the amount of air supplied in excess, resulting in lower thermal efficiency than fuel consumption. There were various disadvantages.

본 고안의 목적은 이와같은 종래의 단점을 해소하는 데 있는 것으로, 노즐의 분사공의 외주로 외통의 급기공을 통해 고순도 산소를 직접 공급시키므로서 연소를 촉진시켜 완전연소를 일으켜 고열의 화열을 발생시키고 열효율을 높일 수 있는 개량 노즐을 제공코자 한 데 있는 것이다.The purpose of the present invention is to solve such a drawback of the prior art, by supplying high-purity oxygen directly through the air supply hole of the outer cylinder to the outer circumference of the nozzle injection hole to promote the combustion to generate complete combustion to generate high heat of heat It is to provide an improved nozzle that can improve the thermal efficiency.

In the normal nozzle (9), which is fitted and screwed into the rear end of the oil filter (8), the outer cylinder (10) closely connected to the outer surface of the inner cylinder (1) is screwed and the inner cylinder (1) on its outer surface. A plurality of air supply through the high-purity oxygen supply hole 12 communicating with the air chamber 11, which is concave in the middle outer surface of the inner cylinder 1, and in communication with the air chamber 11 on the outer surface of the tip tapered surface 13 of the inner cylinder 1 The grooves 14 and 14 'are characterized in that they are arranged at regular intervals.

도면중 미설명 부호 15는 버너이고, 16은 열교환기이며, 17은 고순도 산소 발생기이고, 18은 연도이며, 19는 연료탱크이다.In the figure, reference numeral 15 is a burner, 16 is a heat exchanger, 17 is a high purity oxygen generator, 18 is a flue, and 19 is a fuel tank.

이와같이 된 본 고안의 버너용 노즐은 연료탱크(19)로 부터 공급되는 연료가 노즐(9)의 후단에 나사끼움된 오일필터(8)를 통해 이물질이 여과된 후 내통(1)의 내부로 유입되면 오일 유도구(7)의 오일공(6)으로 배출된 오일이 안내봉(5)의 선단에 형성된 와류홈(4)을 통해 와류되는 상태로 분사판(3)의 분사공(2)으로 분사되면서 오일을 버너(15)로 송풍되는 공기와 연소시켜 화열을 발생시키게 되는 데 여기서 내통(1)의 외면에는 이와 밀접하는 외통(10)을 관삽시켜 이에 고순도 산소 공급공(12)을 내통(1)외면의 공기실(11)과 연통되게 관통시킨 것이므로 도 3에 도시한 바와 같이 고순도 산소 발생기(17)에서 발생된 고순도 산소를 산소 공급공(12)을 통해 공급시키면 고순도 산소는 내통(1)의 외면에 요입 형성된 공기실(11)로 유입되는 데 내통(1)의 선단 테이퍼면(13)에는 상기한 공기실(11)과 연통하는 다수개의 급기홈(14)(14')이 일정간격으로 요설되어 있으므로 고순도 산소 공급공(12)을 통해 공기실(11)로 유입된 고순도 산소는 테이퍼면(13)의 급기홈(14)(14')으로 고압으로 압출되어 분사공(2)의 외측에서 강하게 분사됨에 따라 분사공(2)으로 분사되는 연료는 분사공(2)으로 분출됨과 동시에 고순도의 산소에 의해 완전 연소가 되어 화열을 발생시키게 되므로 고열이 발생하게 되어 열효율이 극대화 되는 것이다.In the burner nozzle of the present invention, the fuel supplied from the fuel tank 19 flows into the inside of the inner cylinder 1 after the foreign matter is filtered through the oil filter 8 screwed into the rear end of the nozzle 9. When the oil discharged into the oil hole (6) of the oil guide port 7 is vortexed through the vortex groove (4) formed at the tip of the guide rod (5) to the injection hole (2) of the injection plate (3) As the oil is injected, the oil is burned with the air blown into the burner 15 to generate heat. Here, the outer surface of the inner cylinder 1 is inserted into the outer cylinder 10 which is in close contact with the high-purity oxygen supply hole 12. 1) Since it penetrates to communicate with the air chamber 11 on the outer surface, as shown in FIG. 3, when the high purity oxygen generated by the high purity oxygen generator 17 is supplied through the oxygen supply hole 12, the high purity oxygen is supplied to the inner cylinder 1. Flows into the air chamber 11 recessed on the outer surface of the Since the plurality of air supply grooves 14, 14 'communicating with the air chamber 11 are contemplated at regular intervals, the high purity oxygen introduced into the air chamber 11 through the high purity oxygen supply hole 12 is tapered. The fuel injected into the injection hole 2 is ejected into the injection hole 2 as it is extruded at high pressure into the air supply grooves 14 and 14 ′ of the surface 13 and is strongly injected from the outside of the injection hole 2. It is completely burned by high purity oxygen and generates heat, so high heat is generated and thermal efficiency is maximized.

본 고안의 노즐(9)은 이상과 같이 노즐자체에 고순도의 산소를 공급하게 되므로 종래와 같이 버너의 송풍량을 매우 미약하게 하거나 또는 송풍을 폐쇄하여도 연료가 분사공(2)으로 분사되는 즉시 고순도 산소에 의해 완전연소가 이루어지게 됨에 따라 열교환기(16)를 통과하는 공기량이나 속도를 극소화 시킬 수 있어 대기중에 방출되는 열량을 대폭 감소시킬 수 있으므로 에너지 효율을 높일 수 있고 방출열이 적어 연도를 매우 작게 설치할 수 있어 대기오염도 줄일 수 있는 것이다.Since the nozzle 9 of the present invention supplies high-purity oxygen to the nozzle itself as described above, even if the blowing amount of the burner is very weak as in the prior art or the blowing is closed, the fuel is injected into the injection hole 2 immediately. As the complete combustion is carried out by oxygen, the amount of air passing through the heat exchanger 16 can be minimized and the speed can be greatly reduced, which can greatly reduce the amount of heat released into the atmosphere, thereby improving energy efficiency and reducing the amount of heat emitted. Small installations can reduce air pollution.

이와같이 본 고안은 노즐(9)의 분사공(2)을 향해 고순도의 산소를 직접 공급하게 되므로 완전연소가 이루어져 열효율이 극대화되고 에너지를 절감할 수 있으며 대기오염도 줄일 수 있는 등 그 효과가 매우 큰 우수한 고안이다.As such, the present invention directly supplies high-purity oxygen toward the injection hole 2 of the nozzle 9, so that the combustion is completely performed, thereby maximizing thermal efficiency, saving energy, and reducing air pollution. It is devised.
