Description

난방기용 연소장치Burner for heater

본 고안은 보일러 등의 난방기용 연소장치에 관한 것으로, 특히 연료연소에 필요한 연소용공기를 공급하는 송풍구 전면 중앙에 연료관을 구성하여, 연소용공기 송출시 연료관 전면에 생기는 진공현상에 의하여 연료탱크의 연료가 분사되도록 구성한 것으로, 연료분사시 분사되는 연료가 전방뿐만아니라 외측방향으로도 분사되어 연소공기와 혼합되어 연소되어 연소효율 및 열효율을 증가시킬 뿐만아니라, 그 구조 또한 단순하여 별도의 장치가 필요치 않는 등의 효과를 제공하는 난방기용 연소장치에 관한 것이다.The present invention relates to a combustion apparatus for a heater such as a boiler, and in particular, a fuel pipe is formed at the center of the front side of a tuyeres for supplying combustion air necessary for fuel combustion, and fuel is discharged by the vacuum phenomenon generated at the front of the fuel pipe when the combustion air is discharged. It is configured to inject the fuel in the tank, and the fuel injected during the fuel injection is injected not only in the front direction but also in the outward direction, mixed with combustion air to combust to increase the combustion efficiency and thermal efficiency, and its structure is also simple and separate device The present invention relates to a combustion apparatus for a heater that provides an effect such as not being necessary.

일반적으로 연소장치는 연료를 연소시키기위한 연소공기를 분출하는 송풍기와는 별도로, 연료를 연소용공기 내로 분사시키기위한 연료분사장치를 구비하고 있다. 즉, 송풍기에 의한 연소용공기가 보일러 내로 진입될 때, 연소용공기 중앙에 위치되어있는 연료 분사장치에 의해, 고압의 연료가 연소용공기와 같은 방향으로 분사되어 연소되게 되어있다. 이를위해 고압의 연료펌프 등을 이용하여 연료를 분사하도록 되어있으며, 이러한 고압의 연료펌프를 사용할 경우 작은 분사구멍을 갖는 분사노즐의 마모가 심하게 되고, 일정 압력에 의한 일정량의 연료분사가 이루어져 적합연소 공기량과 혼합되어 연소되어야 연소효율이 증가 하는데 각 부품의 정밀 제작이 필요하게되어 제작가격의 상승을 초래하며 장기간 사용할 때 초기의 조정상태를 유지시킬수 없어서, 미연소 상태가되어 끄으름의 형태로 불완전 연소를 하게된다. 즉 보일러용 난방기의 연소효율 및 열효율이 저하되는 단점을 갖게된다.In general, a combustion apparatus is provided with a fuel injection device for injecting fuel into combustion air, apart from a blower that blows combustion air for burning fuel. That is, when the combustion air by the blower enters the boiler, the high pressure fuel is injected in the same direction as the combustion air and combusted by the fuel injector located in the center of the combustion air. For this purpose, the fuel is injected using a high pressure fuel pump, and when the high pressure fuel pump is used, the injection nozzle having a small injection hole is severely worn, and a certain amount of fuel injection is carried out by a certain pressure, which makes it suitable for combustion. Combustion must be mixed with air volume to increase combustion efficiency, which requires precise manufacturing of each part, which leads to an increase in manufacturing price and cannot maintain initial adjustment when used for a long time, resulting in unburned state and incomplete form. Burning. In other words, the combustion efficiency and thermal efficiency of the heater for the boiler is deteriorated.

본 고안은 난방기용 연소장치에 관한 것으로, 특히 연소 연료와 혼합되어 연소효율을 증대시키는 연소용공기를 송풍기로부터 분사시키는 다수의 구멍인 송풍구의 중심에 연료관이 위치되도록 구성한 것으로, 송풍구에서 연소용공기가 어떤 일정압력 이상을 가질 때 공가분출 속도는 일정하게되는 원리를 이용하여 연료관 주위로 공기가 강하게 분출되면 바람이 나오지 않는 연료관 주위는 순간 상대적으로 진공현상이 발생하게되며, 이로서 연료탱크의 연료가 연료관을 따라 일정량 분출되어 송풍구의 연소용공기와 혼합되어 분사되도록 구성한 난방기용 연소장치에 관한 것으로, 종래와 같이 별도의 연료분사장치가 필요치않는 단순구조로 구성되어있으며, 진공에의해 분출된 연료가 와류실에 의해 전면·외측으로 분출되는 연소공기와 서로 혼합되어 분사되어 연소되므로, 완전연소에의해 연소효율과 열효율이 증대되도록 구성한 것이다.The present invention relates to a combustion apparatus for a heater, and in particular, the fuel pipe is located in the center of the tuyere, which is a plurality of holes for injecting the combustion air from the blower mixed with the combustion fuel to increase the combustion efficiency, the combustion for When the air has a certain pressure or higher, the idle jet velocity is constant. If the air is strongly blown around the fuel pipe, a vacuum phenomenon is generated around the fuel pipe without the wind. Is a combustion apparatus for a heater, which is configured to eject a certain amount of fuel along a fuel pipe and is mixed with the combustion air of a tuyere and injected, and has a simple structure that does not require a separate fuel injection device as in the prior art. The injected fuel is mixed with the combustion air ejected to the front and the outside by the vortex chamber.

Therefore, the injection air 16 is configured to move forward outside the vacuum portion A to suck the air in the front portion of the fuel tube 11, so that the air in the fuel tube 11 is To fill the seat, the fuel of the fuel tank 4, which is connected to the fuel pipe 11, enters the vacuum unit A again. As the combustion air 15 and the injection air 16 are gradually spread outward by the vortex chamber 12, the injection fuel 17 entering the vacuum unit A is also ejected forward to spread outward as it is advanced. As a result, the injection fuel 17 is configured to mix well with the combustion air 15 and the injection air 16 on the outside so as to be completely burned.
