Description

버너장치Burner device
본 발명의 실시예는 버너장치에 관한 것으로, 더욱 상세하게는 배기가스를 승온시킬 수 있는 버너장치에 관한 것이다.Embodiment of the present invention relates to a burner device, and more particularly to a burner device capable of raising the temperature of the exhaust gas.
일반적으로 버너장치는 내부에 설치된 연료 공급부와 점화부에 의해 연료를 연소시켜 화염을 생성한다. 생성된 화염은 유입된 배기가스를 승온시킨다. 구체적으로, 화염은 연소실에서 생성된다. In general, the burner device generates a flame by burning fuel by a fuel supply unit and an ignition unit installed therein. The resulting flames heat up the incoming exhaust gas. Specifically, the flame is produced in the combustion chamber.
종래에는 연소실에서 생성된 화염의 열에너지를 버너장치의 외부의 온도로 인해 손실되는 것을 방지하기 위해 버너장치의 외부를 단열재로 감싸야 했다. 이로 인해, 버너장치의 설치공간의 자유도에 의한 제약 및 단열재에 의한 비용이 많이 소모되는 문제점이 있었다.Conventionally, in order to prevent the heat energy of the flame generated in the combustion chamber from being lost due to the temperature outside the burner device, the outside of the burner device had to be wrapped with insulation. For this reason, there is a problem in that the cost due to the constraint of the freedom of installation space of the burner device and the insulation material are consumed much.
또한, 연소실로 유입된 배기가스가 화염의 생성시 방해되는 유동을 가져, 유입된 배기가스로 인해 화염이 편향되어 생성되는 문제점이 있다. 이러한 경우, 버너장치의 연소실이 가열되거나 배기가스를 효과적으로 승온시키기 어려운 문제점이 있다.In addition, there is a problem in that the exhaust gas introduced into the combustion chamber has a flow that is disturbed when generating the flame, and the flame is deflected due to the introduced exhaust gas. In this case, there is a problem in that the combustion chamber of the burner device is difficult to heat or effectively raise the exhaust gas.
본 발명의 실시예는 배기가스를 효과적으로 승온시킬 수 있는 버너장치를 제공한다.Embodiment of the present invention provides a burner device that can effectively increase the temperature of the exhaust gas.
본 발명의 실시예에 따르면, 배기가스를 승온 시키는 버너장치는 외부 하우징과, 일단부가 상기 외부 하우징의 일단부와 이격되어 상기 외부 하우징 내부에 배치되며 타단부가 상기 외부 하우징의 타단부에 지지되고 연소실을 형성하는 내부 하우징과, 상기 외부 하우징의 일단부와 상기 내부 하우징의 일단부 사이에 배치된 다공부재와, 상기 외부 하우징의 내주면과 상기 내부 하우징의 외주면 사이를 이격시켜 지지하는 제1 지지부재, 그리고 상기 다공부재와 상기 내부 하우징 사이를 이격시켜 지지하는 제2 지지부재를 포함한다.According to an embodiment of the present invention, a burner device for heating up exhaust gas has an outer housing, one end of which is spaced apart from one end of the outer housing and disposed inside the outer housing, and the other end of which is supported at the other end of the outer housing. An inner housing forming a combustion chamber, a porous member disposed between one end of the outer housing and one end of the inner housing, and a first support member spaced apart from and supported by an inner circumferential surface of the outer housing and an outer circumferential surface of the inner housing.

배기가스 유입구(130)로 유입된 배기가스는 제1 지지부재(400)가 외부 하우징(100)과 내부 하우징(200) 사이를 서로 이격시켜 형성한 제1 공간(S1)을 통과하며 연소실(210) 외부를 감싸며 외부 하우징(100)의 일단부를 향하는 방향으로 이동할 수 있다.The exhaust gas introduced into the exhaust gas inlet 130 passes through the first space S1 formed by the first support member 400 spaced apart from the outer housing 100 and the inner housing 200, and the combustion chamber 210. The outer cover may move in a direction toward one end of the outer housing 100.
또한, 외부 하우징(100)의 일단부로 이동된 배기가스는 다공부(330)의 복수의 홀(331)과, 제2 지지부재(500)가 제2 다공 지지부(320)와 내부 하우징(200) 사이를 서로 이격시켜 형성한 제2 공간(S2)을 통과하여 연소실(210)로 공급될 수 있다.In addition, the exhaust gas moved to one end of the outer housing 100 includes a plurality of holes 331 of the porous portion 330, and the second supporting member 500 includes the second porous supporting portion 320 and the inner housing 200. It may be supplied to the combustion chamber 210 through the second space (S2) formed to be spaced apart from each other.
따라서, 버너장치(101)의 동작 초기 연소실(210)의 외부가 제1 공간(S1)을 통과하는 배기가스에 온도에 의해 승온될 수 있다. 또한, 제1 공간(S1)을 통과하는 배기가스에 의해 연소실(210)의 화염에 의해 승온된 배기가스가 외부 하우징(100)의 외부 온도에 의해 손실되는 열손실을 저감시킬 수 있다. Therefore, the outside of the operation initial combustion chamber 210 of the burner device 101 may be heated up by temperature to the exhaust gas passing through the first space S1. In addition, the heat loss in which the exhaust gas heated up by the flame in the combustion chamber 210 by the exhaust gas passing through the first space S1 is lost by the external temperature of the outer housing 100 can be reduced.
그리고, 본 발명의 버너장치(101)는 제1 공간(S1)을 통과하는 배기가스에 의해 종래 버너장치의 열손실을 저감 시키기 위해 버너장치의 외부를 단열재로 감싸는 비용을 효과적으로 줄일 수 있다.And, the burner device 101 of the present invention can effectively reduce the cost of wrapping the outside of the burner device with a heat insulating material in order to reduce the heat loss of the conventional burner device by the exhaust gas passing through the first space (S1).
또한, 본 발명의 버너장치(101)의 배기가스 유입구(130)를 통해 유입된 배기가스 중 다공부재(300)와 내부 하우징(200) 사이를 통과하는 배기가스의 유량이 다공부(330)를 통과하는 배기가스의 유량보다 클 수 있다.In addition, the flow rate of the exhaust gas passing between the porous member 300 and the inner housing 200 of the exhaust gas introduced through the exhaust gas inlet 130 of the burner device 101 of the present invention is the porous portion 330 It may be greater than the flow rate of the exhaust gas passing through.
배기가스 유입구(130)를 통해 유입된 배기가 중 다공부재(300)와 내부 하우징(200) 사이의 제2 공간(S2)을 통해 연소실(210)로 유입되는 배기가스의 유량은 다공부(330)의 복수의 홀(331)을 통해 연소실(210)로 유입되는 배기가스의 유량보다 클 수 있다.The flow rate of the exhaust gas introduced into the combustion chamber 210 through the second space S2 between the porous member 300 and the inner housing 200 of the exhaust gas introduced through the exhaust gas inlet 130 is the porous portion 330.

Therefore, such a high flow rate exhaust gas may allow the high temperature exhaust gas to be effectively supplied to the combustion chamber 210 while maintaining the temperature.
또한, 다공부(330)의 복수의 홀(331)을 통해 연소실(210)로 공급되는 배기가스는 균일한 유동을 가지며 연소실(210)로 공급될 수 있다. 그리고, 연소실(210) 내부에 생성된 화염이 다공부재(300)에 점착되는 경우에도, 복수의 홀(331)을 통과하는 배기가스에 의해 화염과 다공부재(300) 사이가 효과적으로 이격될 수 있다.In addition, the exhaust gas supplied to the combustion chamber 210 through the plurality of holes 331 of the porous part 330 may have a uniform flow and may be supplied to the combustion chamber 210. In addition, even when the flame generated inside the combustion chamber 210 adheres to the porous member 300, the flame and the porous member 300 may be effectively spaced apart by the exhaust gas passing through the plurality of holes 331. .
일예로, 다공부재(300)와 내부 하우징(200) 사이의 제2 공간(S2)을 통해 연소실(210)로 유입되는 배기가스의 유량은 다공부(330)의 복수의 홀(331)을 통해 연소실(210)로 유입되는 배기가스의 유량보다 15% 내지 20% 많을 수 있다.For example, the flow rate of the exhaust gas flowing into the combustion chamber 210 through the second space S2 between the porous member 300 and the inner housing 200 is provided through the plurality of holes 331 of the porous portion 330. The flow rate of the exhaust gas flowing into the combustion chamber 210 may be 15% to 20% higher.

신기 유입부(600)는 외부 하우징(100)의 일단부와 연결되어 연소실(210)로 신기(新氣)가 유입되도록 안내할 수 있다. 구체적으로, 신기 유입부(600)는 외부 하우징(100)의 제1 관통홀(110)이 형성된 외부 하우징(100)의 일측에 연결된다. 즉, 신기 유입부(600)는 제1 관통홀(110)에 의해 지지될 수 있다. 신기 유입부(600)를 통해 연소실(210) 내부로 유입되는 신기는 연소 필요한 산소를 포함하고 있다.The fresh air inlet 600 may be connected to one end of the outer housing 100 to guide the fresh air to the combustion chamber 210. Specifically, the novel air inlet 600 is connected to one side of the outer housing 100 in which the first through hole 110 of the outer housing 100 is formed. That is, the novel inlet 600 may be supported by the first through hole 110. The fresh air flowing into the combustion chamber 210 through the fresh air inlet 600 includes oxygen required for combustion.
따라서, 신기 유입부(600)를 통해 공급되는 신기에 의해 연소실(210) 내부에 생성된 화염이 안정적으로 화염을 유지할 수 있다.Therefore, the flame generated inside the combustion chamber 210 by the fresh air supplied through the fresh air inlet 600 may stably maintain the flame.

The fresh air can be mixed to allow the exhaust gas to be burned effectively.
또한, 본 발명의 일 실시예에 따른 제1 지지부재(400)는, 앞서 서술한 도 1 및 앞서 서술한 도 3에 도시한 바와 같이, 복수의 내부 하우징 지지부(410)를 포함할 수 있다.In addition, the first support member 400 according to an embodiment of the present invention may include a plurality of inner housing support parts 410, as shown in FIG. 1 and FIG. 3 described above.
제1 지지부재(400)는 외부 하우징(100)의 길이방향을 따라 형성될 수 있다. 또한, 제1 지지부재(400)는 외부 하우징(100)의 내주면으로부터 내부 하우징(200)의 외주면을 향해 방사상으로 서로 이격되어 배치된 복수의 내부 하우징 지지부(410)를 포함할 수 있다.The first support member 400 may be formed along the longitudinal direction of the outer housing 100. In addition, the first support member 400 may include a plurality of inner housing support parts 410 disposed radially spaced apart from each other toward the outer circumferential surface of the inner housing 200 from the inner circumferential surface of the outer housing 100.
구체적으로, 제1 지지부재(400) 일단부는 외부 하우징(100)의 내주면과 결합되고, 제1 지지부재(400)의 타단부는 내부 하우징(200)의 외주면과 접촉할 수 있다.Specifically, one end of the first support member 400 may be coupled to the inner circumferential surface of the outer housing 100, and the other end of the first support member 400 may contact the outer circumferential surface of the inner housing 200.
또한, 제1 지지부재(400)의 타단부는 내부 하우징(200)과 선 또는 점 접촉될 수 있다. 일예로, 제1 지지부재(400)의 타단부는 단면이 원형을 포함하는 접촉면(411)을 포함할 수 있다. In addition, the other end of the first support member 400 may be in line or point contact with the inner housing 200. For example, the other end of the first support member 400 may include a contact surface 411 having a circular cross section.
따라서, 제1 지지부재(400)가 내부 하우징(200)과 접촉되어 있어, 내부 하우징(200)이 형성하는 연소실(210)에서 생성되는 화염에 의해 내부 하우징(200)이 팽창하여도 외부 하우징(100)의 열변형 없이 제1 지지부재(400)가 내부 하우징(200)의 열변형을 효과적으로 지지할 수 있다.Therefore, since the first support member 400 is in contact with the inner housing 200, even if the inner housing 200 is expanded by a flame generated in the combustion chamber 210 formed by the inner housing 200, the outer housing ( The first support member 400 may effectively support the thermal deformation of the inner housing 200 without the thermal deformation of the 100.
즉, 내부 하우징(200)이 연소실(210)에서 생성된 화염에 의한 열변형으로 내부 하우징(200)의 일단부를 향해 슬립(slip)이 발행하는 경우, 제1 지지부재(400)의 접촉면(411)에 의해 외부 하우징(100)의 변형 없이 내부 하우징(200)의 열변형을 효과적으로 지지할 수 있다.That is, when a slip is issued toward one end of the inner housing 200 due to heat deformation caused by the flame generated in the combustion chamber 210, the inner housing 200 may contact the surface 411 of the first support member 400. By it can be effectively supported the thermal deformation of the inner housing 200 without deformation of the outer housing (100).
또한, 본 발명의 일 실시예에 따른 제2 지지부재(500)는 복수의 다공부재 지지부(510)를 포함할 수 있다.In addition, the second support member 500 according to an embodiment of the present invention may include a plurality of porous member supporters 510.
제2 지지부재(500)는 다공부재(300)의 외주면으로부터 내부 하우징(200)의 일단부의 내주면을 향해 방사상으로 서로 이격되어 배치된 복수의 다공부재 지지부(510)를 포함할 수 있다.The second support member 500 may include a plurality of porous member supporters 510 disposed radially spaced apart from each other radially from the outer circumferential surface of the porous member 300 toward the inner circumferential surface of one end of the inner housing 200.
제2 지지부재(500)는 다공부재(300)의 제2 다공 지지부(320)의 외주면으로부터 내부 하우징(200)의 일단부의 내주면을 향해 방사상으로 서로 이격되어 배치될 수 있다. 즉, 제2 지지부재(500)는 다공부재(300)의 제2 다공 지지부(320) 중 내부 하우징(200)의 일단부에 삽입된 일영역의 외주면과 내부 하우징(200) 사이에 방사상으로 서로 이격되어 배치된 복수의 다공부재 지지부(510)를 포함할 수 있다.The second support member 500 may be radially spaced apart from each other radially from the outer circumferential surface of the second porous support portion 320 of the porous member 300 toward the inner circumferential surface of one end of the inner housing 200. That is, the second support member 500 is radially disposed between the outer circumferential surface of one region inserted into one end of the inner housing 200 of the second porous support part 320 of the porous member 300 and the inner housing 200. It may include a plurality of porous member support 510 disposed to be spaced apart.
구체적으로, 제2 지지부재(500)의 일측은 다공부재(300)의 제2 다공 지지부(320)와 결합되고, 제2 지지부재(500)의 타측은 내부 하우징(200)의 내주면과 접촉될 수 있다. 또한, 제2 지지부재(500)는 제1 지지부재(400)가 갖는 접촉면(411)을 동일하게 포함할 수 있다.Specifically, one side of the second support member 500 is coupled to the second porous support part 320 of the porous member 300, and the other side of the second support member 500 is in contact with the inner circumferential surface of the inner housing 200. Can be. In addition, the second support member 500 may include the same contact surface 411 of the first support member 400.
따라서, 연소실(210)에서 발생된 화염에 의해 다공부재(300)가 열변형이 발생한 경우에도, 제2 지지부재(500)에만 지지된 다공부재(300)의 슬립을 제2 지지부재(500)가 효과적으로 지지할 수 있다.Accordingly, even when the porous member 300 is thermally deformed due to the flame generated in the combustion chamber 210, the slip of the porous member 300 supported only by the second supporting member 500 may be applied to the second supporting member 500. Can effectively support.
즉, 다공부재(300)는 버너장치(101)의 구성 중 제2 지지부재(500)에 의해 지지됨으로 다른 구속 조건이 없어, 열변형에 의한 슬립이 발생하는 경우에도 제2 지지부재(500)가 이동하는 다공부재(300)를 효과적으로 지지할 수 있다.That is, since the porous member 300 is supported by the second support member 500 among the components of the burner device 101, there is no other restraint condition, even when slip due to thermal deformation occurs. It can effectively support the porous member 300 is moved.
이하, 도 1 내지 도 5를 참조하여, 본 발명의 버너장치(101)를 포함하는 시스템(102)의 작동과정에 관해 설명한다.Hereinafter, the operation of the system 102 including the burner device 101 of the present invention will be described with reference to FIGS. 1 to 5.
엔진(10)은 연료를 연소시켜 동력을 생성한다. 이때, 엔진(10)은 배기가스를 배출한다. 엔진(10)으로부터 배출된 배기가스는 터빈(20)을 통과하며 메인 배기유로(80)를 통과한다.The engine 10 burns fuel to generate power. At this time, the engine 10 discharges exhaust gas. The exhaust gas discharged from the engine 10 passes through the turbine 20 and passes through the main exhaust passage 80.
메인 배기유로(80) 상에는 배기가스에 포함된 질소 산화물을 정화시킬 수 있는 촉매가 내부에 설치된 반응기(60)가 설치된다.On the main exhaust passage 80, a reactor 60 in which a catalyst capable of purifying nitrogen oxides contained in the exhaust gas is installed.
또한, 반응기(60) 전방의 메인 배기유로(80)를 통과하는 배기가스는 일부가 분기 배기유로(70)를 통해 분기되어 다시 반응기(60) 전방의 메인 배기유로(80)와 연결된다.In addition, a part of the exhaust gas passing through the main exhaust flow path 80 in front of the reactor 60 is branched through the branch exhaust flow path 70 to be connected to the main exhaust flow path 80 in front of the reactor 60 again.
분기 배기유로(70) 상에는 블로워(30)와 버너장치(101)와 분해챔버(40)와 분사부재(50)가 설치될 수 있다.The blower 30, the burner device 101, the decomposition chamber 40, and the injection member 50 may be installed on the branch exhaust passage 70.
블로워(30)는 메인 배기유로(80)를 통과하는 배기가스의 일부가 분기 배기유로(70)를 통해 유입되도록 유체의 이동동력을 제공한다. 따라서, 블로워(30)는 버너장치(101)의 배기가스 유입구(130)로 배기가스가 유입되도록 할 수 있다.The blower 30 provides a moving power of the fluid such that a part of the exhaust gas passing through the main exhaust flow path 80 flows through the branch exhaust flow path 70. Accordingly, the blower 30 may allow the exhaust gas to flow into the exhaust gas inlet 130 of the burner device 101.
버너장치(101)의 배기가스 유입구(130)로 유입된 배기가스는 외부 하우징(100)과 내부 하우징(200) 사이의 제1 공간(S1)을 통과한다. 따라서, 배기가스는 제1 공간(S1)을 따라 내부 하우징(200)의 외주면을 따라 외부 하우징(100)의 일단부를 향해 이동한다.The exhaust gas introduced into the exhaust gas inlet 130 of the burner device 101 passes through the first space S1 between the outer housing 100 and the inner housing 200. Therefore, the exhaust gas moves along the outer space of the inner housing 200 along the first space S1 toward one end of the outer housing 100.
외부 하우징(100)의 일단부로 이동된 배기가스는 다공부재(300)와 내부 하우징(200) 사이의 제2 공간(S2)을 통과하여 연소실(210)로 유입되거나, 다공부재(300)의 다공부(330)를 통해 연소실(210)로 유입될 수 있다.Exhaust gas moved to one end of the outer housing 100 passes through the second space S2 between the porous member 300 and the inner housing 200 and enters the combustion chamber 210, or the porous member 300 is closed. Through the study 330 may be introduced into the combustion chamber (210).
따라서, 다공부(330)를 통과한 배기가스는 유동이 균일화 되어 연소실(210)로 공급시 연소실(210)에서 생성되는 화염의 생성을 방해하지 않을 수 있다. 또한, 제2 공간(S2)을 통해 공급된 배기가스는 빠른 유속을 갖고 연소실(210) 내벽을 향해 공급될 수 있어 화염의 생성을 방해하지 않을 수 있다.Therefore, the exhaust gas passing through the porous part 330 may not prevent the generation of the flame generated in the combustion chamber 210 when the flow is uniformly supplied to the combustion chamber 210. In addition, the exhaust gas supplied through the second space S2 may be supplied toward the inner wall of the combustion chamber 210 with a high flow rate and may not prevent the generation of flame.
신기 유입부(600)를 통해 유입되는 신기와 제2 공간(S2)을 통과해 연소실(210)에 공급되는 배기가스와 다공부(330)를 통과해 연소실(210)에 공급되는 배기가스는 혼합부(700)에 의해 혼합될 수 있다.Exhaust gas supplied through the fresh air inlet 600 and the second gas space S2 passed through the second chamber S2 and the exhaust gas supplied to the combustion chamber 210 through the porous part 330 are mixed. May be mixed by the part 700.
따라서, 혼합부(700)는 배기가스가 연소실(210)에서 승온시 효과적으로 승온될 수 있도록 신기와 혼합할 수 있다.Therefore, the mixing unit 700 may mix with the wearer so that the exhaust gas can be effectively heated up when the temperature rises in the combustion chamber 210.
연소실(210)을 통과하는 신기와 혼합된 배기가스는 화염에 의해 승온되어, 배출구(220)를 통해 버너장치(101) 외부로 배출될 수 있다.Exhaust gas mixed with the new chamber passing through the combustion chamber 210 may be heated up by the flame, and discharged to the outside of the burner device 101 through the outlet 220.
승온된 배기가스는 환원제 분해 챔버(40)로 공급된다. 분해챔버(40)는 승온된 배기가스의 열에너지로 공급되는 우레아(Urea)를 가수분해시킬 수 있다.The heated exhaust gas is supplied to the reducing agent decomposition chamber 40. The decomposition chamber 40 may hydrolyze urea supplied by the thermal energy of the heated exhaust gas.
가수분해된 환원제는 분사부재(50)를 통해 반응기(60) 전방의 메인 배기유로(80) 상에 분사될 수 있다.The hydrolyzed reducing agent may be injected onto the main exhaust flow path 80 in front of the reactor 60 through the injection member 50.
따라서, 반응기(60)로 유입되는 배기가스는 가수분해된 환원제와 혼합될 수 있다.Therefore, the exhaust gas flowing into the reactor 60 may be mixed with the hydrolyzed reducing agent.
반응기(60)를 통과하여 반응기 후방의 메인 배기유로(80)를 통해 질소산화물을 포함하는 배기가스는 질소와 물 또는 수증기로 분해되어 외부로 배출될 수 있다.Exhaust gas including nitrogen oxide may be discharged to the outside by being decomposed into nitrogen and water or water vapor through the main exhaust passage 80 behind the reactor through the reactor 60.
이와 같은 구성에 의해, 본 발명의 일 실시예에 따른 버너장치(101)는 배기가스를 효과적으로 승온시킬 수 있다.By such a configuration, the burner device 101 according to the embodiment of the present invention can effectively increase the exhaust gas temperature.
구체적으로, 버너장치(101)는 외부 하우징(100)과 내부 하우징(200) 그리고 이들 사이를 지지하는 제1 지지부재(400)에 의해 내부 하우징(200)이 형성하는 연소실(210)에서 생성된 화염에 의해 내부 하우징(200)에 열변형이 발생하여도 외부 하우징(100)에 영향없이 내부 하우징(200)을 효과적으로 지지할 수 있다.Specifically, the burner device 101 is generated in the combustion chamber 210 formed by the inner housing 200 by the outer housing 100 and the inner housing 200 and the first support member 400 supporting therebetween. Even if heat deformation occurs in the inner housing 200 due to the flame, the inner housing 200 may be effectively supported without affecting the outer housing 100.
또한, 외부 하우징(100)과 내부 하우징(200) 그리고 이들 사이를 이격시켜 지지하는 제1 지지부재(400)에 의해, 제1 공간(S1)을 통해 배기가스가 내부 하우징(200)의 외주면을 따라 이동할 수 있어 종래의 버너장치에 비해 연소실의 단열을 유지시키기 위해 필요한 단열재의 사용을 저감시킬 수 있다.In addition, by the outer housing 100, the inner housing 200, and the first support member 400 spaced apart from each other, the exhaust gas is formed on the outer circumferential surface of the inner housing 200 through the first space S1. It can be moved along to reduce the use of the heat insulating material required to maintain the heat insulation of the combustion chamber compared to the conventional burner device.
그리고, 다공부재(300)를 통과한 배기가스가 균일한 유동을 갖고 연소실(210)에 유입될 수 있어, 연소실(210) 내부에서 불균일한 유동의 유체 유입에 의한 화염생성의 방해를 방지할 수 있다.In addition, the exhaust gas having passed through the porous member 300 may be introduced into the combustion chamber 210 with a uniform flow, thereby preventing the generation of flame due to the inflow of the fluid of the non-uniform flow inside the combustion chamber 210. have.
