Description
본 발명은 완전 연소를 유도하는 화목보일러에 관한 것으로, 더욱 상세하게는 화목연료를 연소할 때 발생하는 고온의 배기가스에 포함된 연기나 그을음 등을 완전히 연소시키는 구조와, 배기가스의 흐름 방향과 물의 흐름 방향이 항류가 되도록 한 구조를 가짐에 따라, 배기가스의 배출시 그을음 등이 배기가스에 포함되는 것을 최소화시켜 열교환관의 막힘과 열전도도의 감소를 방지하고, 화목연료의 에너지 효율 및 급격한 소비를 줄일 수 있는 완전 연소를 유도하는 화목보일러에 관한 것이다.
The present invention relates to a firewood boiler that induces complete combustion, and more particularly, a structure that completely burns smoke or soot, etc. contained in the high-temperature exhaust gas generated when burning the fuel, and the flow direction of the exhaust gas. As the flow direction of the water flows countercurrently, it minimizes the soot and so on included in the exhaust gas when the exhaust gas is discharged, thereby preventing the blockage of the heat exchange tube and reducing the thermal conductivity, and the energy efficiency and rapid The present invention relates to a firewood boiler that induces complete combustion that can reduce consumption.
일반적으로 화목보일러는 화목연료가 투입되는 연소실과, 상기 연소실에 공기를 공급하는 공기유입구와, 상기 연소실에서 발생한 배기가스를 외부로 배출하는 연도와, 상기 연소실에서 발생한 열과 직접적으로 열교환하는 물탱크로 구성된다. Generally, a coal fired boiler is a combustion chamber into which a fossil fuel is injected, an air inlet for supplying air to the combustion chamber, a flue for discharging exhaust gas from the combustion chamber to the outside, and a water tank for directly exchanging heat with heat generated in the combustion chamber. It is composed.
상기 화목보일러의 작동원리는 공기유입구를 통해 공급받은 산소와 화목연료를 연소실에서 전면 연소시키고, 화목연료의 전면연소가 완료되면 공기유입구를 닫아 연소시 발생한 가스를 연도를 통해 외부로 배출하며, 연소실의 온도가 내려가면 공기유입구를 다시 열어 산소를 공급하고, 화목연료를 다시 전면연소시키면서 온수를 생산한다.
The operating principle of the firewood boiler is to completely burn the oxygen and the firewood fuel supplied through the air inlet in the combustion chamber, and when the front combustion of the firewood fuel is completed, close the air inlet to discharge the gas generated during combustion to the outside through the flue, When the temperature drops, the air inlet is opened again to supply oxygen, and the firewood fuel is completely burned again to produce hot water.
그러나 상기한 종래의 화목보일러는 다량의 화목연료를 한번에 연소시키는 구조로 인해 연소에 필요한 산소가 부족하여 화목연료의 완전연소가 이루어지지 못하므로 연소시 발생하는 배기가스에 악취나 그을음 등이 포함되며, 화목연료의 낭비를 초래하는 문제점이 있었다. However, the conventional coal fired boiler has a lack of oxygen required for combustion due to the structure of burning a large amount of coal fired fuel at once, and thus, the exhaust gas generated during combustion includes odor or soot. In other words, there was a problem of causing the waste of a coal fire.
또한 화목연료가 연소실에서 완전히 연소되기 전에 물이 저장된 물탱크와 열교환되는 구조로 인해 연소실 내의 온도가 저하되므로 화목연료가 불완전 연소되어 그을음 등이 포함된 배기가스가 발생하게 되고, 그 배기가스가 연도를 타고 흐르면서 배기가스에 포함된 그을음 등을 연도의 내벽에 부착시켜 배기가스가 가진 열이 물탱크로 전도되는 것을 방해할 뿐만 아니라 연도를 막아 자주 청소해야하는 문제점이 있었다. In addition, since the temperature in the combustion chamber is lowered due to the structure in which the heat exchanged with the water tank in which water is stored before the fuel is completely burned in the combustion chamber, the combustion fuel is incompletely burned, and the exhaust gas including soot is generated. The soot contained in the exhaust gas was attached to the inner wall of the flue as it flowed through the gas, preventing the heat of the exhaust gas from conducting to the water tank as well as preventing the flue from being frequently cleaned.
뿐만 아니라 종래의 화목보일러는 산소부족과 온도저하를 방지하고 반복적인 연소과정를 위한 구조가 없어 화목연료의 연소시 발생하는 가스들 중 반복적인 연소과정을 거처야만 완전히 연소되는 가스를 그대로 외부에 배출하게 되는 문제점 또한 있었다. In addition, conventional coal fired boilers prevent oxygen deficiency and temperature drop and do not have a structure for repetitive combustion process, and thus, exhaust gas that is completely combusted only after repetitive combustion process among the gases generated during combustion of coal fired fuel is discharged to the outside. There was also a problem.
그리고 물탱크가 하부에서 고온으로 가열되고 상부로 갈수록 가열 온도가 낮아짐에 따라 물탱크의 내부에는 무작위로 대류가 발생하여 물의 온도 분포가 고르지 못해 전체적인 열교환 효율을 저하시키는 문제점도 있었다.In addition, as the water tank is heated to a high temperature from the bottom and the heating temperature is lowered toward the top, convection occurs randomly inside the water tank, and there is a problem in that the temperature distribution of the water is uneven, thereby lowering the overall heat exchange efficiency.
따라서 본 발명은 상기와 같은 종래의 문제점을 해소할 수 있도록 화목연료의 완전연소를 유도하고, 열교환이 이루어지는 유체의 흐름이 항류되는 구조를 가진 완전 연소를 유도하는 화목보일러를 제공함에 그 목적이 있다.
Accordingly, an object of the present invention is to provide a firewood boiler which induces complete combustion of a firewood fuel so as to solve the above-mentioned conventional problems and induces a complete combustion having a structure in which a flow of fluid undergoing heat exchange is countercurrent. .

이는 화목연료의 연소시 주연소실(4)의 상부에는 이산화탄소 등과 같은 연소를 방해하는 기체가 모이고 이로 인해 상부에 위치한 화목연료는 연소되지 않아, 주연소실(4)의 하부에 형성된 공기공급공(5)을 통해 산소를 공급 받은 하부의 화목연료만이 연소되기 때문이다. This is because when the combustion of the fossil fuel, gas to prevent combustion such as carbon dioxide is collected in the upper part of the main combustion chamber 4, and thus, the fossil fuel located in the upper part is not burned, and thus the air supply hole 5 formed in the lower part of the main combustion chamber 4 This is because only the lower fossil fuels that are supplied with oxygen are burned.
따라서 화목연료를 한번에 연소하는 것이 아니라 하부부터 차례로 연소하여 화목연료의 사용효율을 종래에 비하여 크게 향상시킬 수 있다. Therefore, instead of burning the fossil fuel at once, the combustion efficiency of the fossil fuel can be greatly improved compared to the conventional one by sequentially burning from the bottom.
그리고 하부에 위치한 화목연료의 연소가 완료되면 연소되지 않은 상부의 화목연료가 중력작용으로 인해 자동으로 산소가 공급되는 주연소실(4)의 하부로 내려와 연소되게 된다. And when the combustion of the fossil fuel located in the lower part is completed, the fossil fuel in the unburned upper part is lowered to the lower part of the main combustion chamber 4 which is automatically supplied with oxygen due to the gravity action.
이때 발생하는 고온의 배기가스는 주연소실(4)의 바닥에 형성된 통기공(3)을 지나 제1연소실(12)과 제2연소실(14) 및 제3연소실(15)로 차례대로 유입된다. At this time, the high-temperature exhaust gas flows into the first combustion chamber 12, the second combustion chamber 14, and the third combustion chamber 15 sequentially through the vent hole 3 formed at the bottom of the main combustion chamber 4.
여기서 제1연소실(12)과 제2연소실(14) 및 제3연소실(15)로 차례대로 유입되는 고온의 배기가스에는 그을음이 포함되어 있는데, 이는 공기공급실(6)에서 제공되는 예열된 공기와 반응하여 연소되면서 거의 완벽하게 제거된다. Here, the high temperature exhaust gas which is sequentially introduced into the first combustion chamber 12, the second combustion chamber 14, and the third combustion chamber 15 includes soot, which is different from the preheated air provided in the air supply chamber 6. Reacts and burns, almost completely removed.
또한 공기공급실(6)의 내벽 중 외부와 접촉하는 내벽에는 내화단열재로 마감되어 본체(1)를 외부와 단열시킴에 따라 주연소실(4)과 제1연소실(12), 제2연소실(14) 및 제3연소실(15)의 온도를 지속적으로 유지할 수 있어 안정적으로 연소가 이루어질 수 있다. In addition, the inner wall in contact with the outside of the inner wall of the air supply chamber (6) is finished with a fire-resistant insulation to insulate the main body 1 from the outside, the main combustion chamber (4), the first combustion chamber 12, the second combustion chamber (14) And it is possible to continuously maintain the temperature of the third combustion chamber 15 can be stably burned.
즉, 이는 보조연소실만이 주연소실(4)의 하부에만 일체로 형성되어 단계별 연소가 이루어지지 않아 화목연료의 완전연소를 유도할 수 없었던 종래와 달리, 보조연소실이 주연소실(4)의 하부에서 일측의 상부까지 구비되고 이를 제1연소실(12)과 제2연소실(14) 및 제3연소실(15)을 단계별로 구획함에 따라 화목연료의 단계별 연소과정을 통해 완전연소를 유도함으로써 가능한 것이다. That is, unlike the conventional combustion chamber in which only the auxiliary combustion chamber is integrally formed only in the lower portion of the main combustion chamber 4, and thus, combustion cannot be induced step by step, the auxiliary combustion chamber is formed in the lower portion of the main combustion chamber 4. It is provided by the upper part of one side and by partitioning the first combustion chamber 12, the second combustion chamber 14 and the third combustion chamber step by step it is possible to induce complete combustion through the stepwise combustion process of the fossil fuel.
그리고 제2연소실(14) 및 제3연소실(15)은 제2연소실(14)과 제3연소실(15)의 양측에 공기공급실(6)을 형성시키는 벤투리관(13)에 의해 구획되고, 상기 벤투리관(13)의 내경이 축소된 부위에 공기공급공(5)이 형성됨에 따라, 공기공급실(6)의 예열된 공기가 제2연소실(14)뿐만 아니라 제3연소실(15)로 유입되면서 연소과정에 필요한 산소를 원활하게 공급할 수 있다. The second combustion chamber 14 and the third combustion chamber 15 are divided by a venturi tube 13 which forms an air supply chamber 6 on both sides of the second combustion chamber 14 and the third combustion chamber 15. As the air supply hole 5 is formed in a portion where the inner diameter of the venturi tube 13 is reduced, the preheated air of the air supply chamber 6 is transferred to the third combustion chamber 15 as well as the second combustion chamber 14. As it flows in, it can smoothly supply oxygen for combustion process.
따라서 상기의 단계적인 연소과정을 통해 화목연료의 완전 연소를 유도하고, 이로 인해 열교환관(8)에 유입되는 고온의 배기가스에 포함된 거을음이 제거되어, 열교환관(8)의 막힘현상을 방지할 뿐만 아니라 추가적으로 발생되는 열을 통해 열효율을 높일 수 있다. Therefore, the above-described combustion process induces the complete combustion of the fossil fuel, thereby eliminating sieves contained in the high-temperature exhaust gas flowing into the heat exchanger tube 8, thereby preventing clogging of the heat exchanger tube 8. In addition to preventing heat, additional heat is generated to increase thermal efficiency.
그리고 벤투리관(13)의 상부 일측에 설치된 받이판(18)은 열교환관(8)의 입구에서 떨어지는 타르 등의 진액을 포집하여 재연소할 뿐만 아니라 제2연소실(14)과 제3연소실(15)의 사이에 형성된 공기공급공(5)의 막힘현상을 줄이게 된다. In addition, the receiving plate 18 installed on the upper side of the venturi tube 13 not only collects and reburns the liquid such as tar falling from the inlet of the heat exchange tube 8, but also burns the second combustion chamber 14 and the third combustion chamber ( The blockage phenomenon of the air supply hole 5 formed between the 15 is reduced.
또한 제2연소실(14)의 상부에는 집진스크린(19)이 설치되어 제1연소실(12)에서 연소되지 않은 그을음 등을 포집하여 재연소되게 한다.In addition, a dust collecting screen 19 is installed at an upper portion of the second combustion chamber 14 to collect and burn the soot that is not burned in the first combustion chamber 12 to be reburned.
상기와 같이 제3연소실(15)을 통과한 고온의 배기가스는 열교환관(8)의 입구로 유입되어 물탱크(11)의 물과 열교환을 하면서 열교환관(8)의 출구로 이동하게 된다. As described above, the high-temperature exhaust gas passing through the third combustion chamber 15 flows into the inlet of the heat exchange tube 8 and moves to the outlet of the heat exchange tube 8 while performing heat exchange with water in the water tank 11.
이때 물과 고온의 배기가스는 물탱크(11)의 유입구(9)가 열교환관(8)의 출구측에 위치하고 물탱크(11)의 유출구(10)가 열교환관(8)의 입구측에 위치하며 물탱크(11)의 내부에 열교환관(8)의 형상에 대응되게 열교환관(8)을 포함하면서 물이 흐르는 공간을 형성하는 격벽(16)이 설치됨에 따라, 물과 배기가스의 항류흐름이 형성되어 열효율을 더욱 향상시킬 수 있다. At this time, the inlet 9 of the water tank 11 is located at the outlet side of the heat exchange tube 8, and the outlet 10 of the water tank 11 is located at the inlet side of the heat exchange tube 8. And the partition wall 16 including the heat exchange tube 8 to form a space in which water flows is installed in the water tank 11 to correspond to the shape of the heat exchange tube 8, so that the flow of water and the exhaust gas flows. This can be formed to further improve the thermal efficiency.
여기서 열교환관(8)의 외주면에는 다수의 열교환핀(7)이 일정간격으로 설치되어 열교환 효율을 증대시킬 수 있다. Here, a plurality of heat exchange fins 7 may be installed on the outer circumferential surface of the heat exchange tube 8 at regular intervals to increase heat exchange efficiency.
또한 열교환관(8)의 출구측에는 도 4와 같이 도 5의 히트파이프(17)가 복수 설치되어 물탱크(11)의 물과 열교환하고 남은 배기가스의 미열마져도 적극적으로 흡열하여 물탱크(11)로 최초 유입된 물과 열교환함에 따라 열교환 효율을 더욱 증대시킨다. In addition, as shown in FIG. 4, a plurality of heat pipes 17 of FIG. 5 are installed at the outlet side of the heat exchanger tube 8 to actively absorb heat even in the heat of the water tank 11 and remaining heat of the exhaust gas remaining in the water tank 11. The heat exchange efficiency is further increased by heat exchange with the first introduced water.
상기한 물탱크(11)와 열교환관(8)이 형성하는 구조를 통해 물의 온도를 단계별로 상승시키므로, 물의 무작위 대류로 인해 화목연료의 소비가 극히 많았던 종래의 화목보일러가의 문제점을 완전히 해소할 수 있다. Since the temperature of the water is increased step by step through the structure formed by the water tank 11 and the heat exchanger tube 8, the problem of the conventional firewood boiler, which consumes a lot of the fuelwood due to the random convection of water, can be completely solved. Can be.
이와 같이 본 발명의 완전 연소를 유도하는 화목보일러(100)는 화목연료를 완전 연소시킴으로써, 배기가스 속에 포함되어 배출되는 그을음을 최소화시키고, 이를 통해 열교환관(8)의 막힘과 열전도도의 감소를 방지하여 화목연료의 에너지 효율을 증대시키고 화목연료의 급격한 소비를 줄일 수 있다.
As such, the firewood boiler 100 inducing complete combustion of the present invention completely burns the firewood fuel, thereby minimizing soot discharged from the exhaust gas, thereby reducing the blockage and heat conductivity of the heat exchanger tube 8. This can increase the energy efficiency of fossil fuels and reduce the rapid consumption of fossil fuels.
