Description

폐열회수의 보일러구조Boiler Structure of Waste Heat Recovery

본 고안은 종래와 달리 송풍기와 버너헤드부를 분리시켜 관체의 소음통을 통해 배기가스로 나가는 열을 회수하여 상기 송풍기로 불어 주어 버너헤드부에서 연소공기로 사용함으로 열효율과 버너의 착화 및 연소시의 화염안정성을 증가시켜 에너지절감을 도모할 수 있는 폐열회수의 보일러구조에 관한 것이다.The present invention separates the blower and the burner head from the prior art, recovers the heat exiting the exhaust gas through the noise chamber of the pipe, blows it to the blower, and uses it as combustion air in the burner head, so that the heat efficiency and burner ignition and combustion The present invention relates to a boiler structure of waste heat recovery capable of increasing energy stability and saving energy.

온수보일러는 별도의 보일러실에 설치하게 되고, 그 주변은 통풍 및 환기가 잘되고 점검 및 보수관리가 가능하도록 적정한 공간확보가 이루어지게 된다.The hot water boiler is installed in a separate boiler room, and the surrounding area is well ventilated and ventilated, and the proper space is secured to enable inspection and maintenance management.

또한, 연료연소시 발생되는 배기가스의 원활한 배출과 연소소음을 줄이기 위해 보일러 물집위에 연도겸용 소음방지기가 설치되어 있다.In addition, in order to reduce the emission and combustion noise of the exhaust gas generated during fuel combustion, the flue-type noise suppressor is installed on the boiler blister.

그러나, 종래의 소음방지기는 소음을 차단하고, 배기가스를 배출하는 역할만 수행하므로 소음저하의 효과가 낮으며, 배기가스로 인해 소음방지기의 상부 표면온도가 높아 별도의 상부단열제를 적용하여야 하며, 또한 배기가스로 손실되는 에너지가 크다는 결점이 있었다.However, since the conventional noise suppressor blocks noise and discharges exhaust gas, the effect of noise reduction is low, and the upper surface temperature of the noise suppressor due to the exhaust gas has to apply a separate upper insulation agent. In addition, there is a drawback that the energy lost to the exhaust gas is large.

이를 감안하여 개발되어진 종래의 폐열회수 보일러구조는 소음통(14)의 일측에 급기출구(17)를 형성시켜 급기호스(18)를 통해 송풍기(15)와 연결되고, 이 송풍기(15)는 모터와 팬으로 구성되어 버너헤드부(16)를 통해 관체(11)와 연결된다.The conventional waste heat recovery boiler structure that has been developed in view of this is connected to the blower 15 through the air supply hose 18 by forming an air supply outlet 17 on one side of the noise chamber 14, and the blower 15 is a motor. And is composed of a fan and is connected to the tubular body 11 through the burner head 16.

이 관체(11)에는 하단부로 연소실(12)이 형성되고, 이 연소실(12)위로 내부 버플의 연관(13)을 통해 상기 소음통(14)이 설치되어 배기가스가 배출된다.A combustion chamber 12 is formed at the lower end of the tubular body 11, and the noise chamber 14 is installed through the tube 13 of the internal buff over the combustion chamber 12 to discharge the exhaust gas.

따라서, 버너의 송풍기(15)로 유입되는 찬공기는 상기 소음통(14)의 급기출구(17)를 통해 열교환, 즉 폐열회수하여 더운공기로 버너헤드부(16)에 보내어져 연소시키므로, 상기 송풍기(15)의 온도가 지나치게 상승되는 원인이 있어 폐열이용 온도의 한계가 있었다.Therefore, the cold air flowing into the blower blower 15 of the burner is heat-exchanged, that is, waste heat recovery through the air supply outlet 17 of the noise chamber 14, so that the hot air is sent to the burner head 16 and burned. Since the temperature of the blower 15 was raised too much, there was a limit of waste heat utilization temperature.

상기한 바와 같이 상기 송풍기(15)과 버너헤드부(16)의 버너에서 공기흐름의 정류가 되지만 송풍기(15)내의 팬이 상기 버너헤드부(16)와 밀착되어 있음으로 불규칙일 수 있어 화염이 불안정할 수 있다.As described above, the air flow is rectified in the burner of the blower 15 and the burner head 16, but the fan in the blower 15 may be irregular because the fan is in close contact with the burner head 16. It can be unstable.

또한, 열교환된 연소용 공기가 송풍기(15)의 모터로 직접 닿기 때문에 모터의 온도를 상승시키므로 열교환시킬 수 있는 온도의 한계가 있었다.In addition, since the heat-exchanged combustion air directly contacts the motor of the blower 15, the temperature of the motor is increased, so there is a limit of the temperature that can be heat-exchanged.

본 고안은 상기와 같은 종래의 폐열회수 보일러구조가 가지고 있는 결점을 해소하기 위해 안출한 것으로, 화염이 안정적이면서 송풍기로 들어오는 배기가스의 이용온도를 더 많이 활용할 수 있도록 종래와 달리 송풍기와 버너헤드부를 분리시켜 관체의 소음통을 통해 배기가스로 나가는 열을 회수하여 상기 송풍기로 불어 주어 버너헤드부에서 연소공기로 사용함으로 열효율과 버너의 착화 및 연소시의 화염안정성을 증가시켜 에너지절감을 도모할 수 있는 폐열회수의 보일러구조를 제공함에 그 목적이 있다.The present invention is devised to solve the drawbacks of the conventional waste heat recovery boiler structure as described above, unlike the conventional blower and burner head portion so that the flame is stable and can utilize more the utilization temperature of the exhaust gas entering the blower. By separating and recovering the heat that goes out to the exhaust gas through the noise chamber of the pipe, it is blown to the blower and used as combustion air in the burner head to increase the thermal efficiency and burn stability of the burner and to promote energy savings. The purpose is to provide a boiler structure for waste heat recovery.

상기 목적을 달성하기 위한 본 고안의 폐열회수의 보일러구조는, 관체(1)에는 하단부로 연소실(2)이, 이 연소실(2)위로 연관(3)을 통해 소음통(4)이 각각 설치되는 보일러에 있어서, 상기 소음통(4)의 열교환부에서 송풍기(5)가, 급기호스(7)를 통해 버너헤드부(6)가 각각 설치되어 상기 버너헤드부(6)의 공기가 더 정류된 공기유로인 것을 그 특징으로 한다.In the boiler structure of the waste heat recovery of the present invention for achieving the above object, the combustion chamber (2) to the lower end in the tubular body (1), respectively, the noise chamber (4) is installed through the tube (3) above the combustion chamber (2), respectively. In the boiler, a blower (5) is installed in the heat exchange part of the noise chamber (4), and a burner head part (6) is provided through an air supply hose (7), whereby the air of the burner head part (6) is further rectified. It is characterized by being an air flow path.

이하, 본 고안의 실시예를 예시도면에 의거하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제2도는 본 고안의 폐열회수의 보일러구조를 도시해 놓은 내부단면도로서, 본 고안은 종래와 달리 급기호스(7)에서 송풍기(5)와 버너헤드부(6)를 분리시켜 관체(1)의 소음통(4)을 통해 배기가스로 나가는 열을 회수하여 상기 송풍기(5)로 불어 주어 버너헤드부(6)에서 연소공기로 사용함으로 열효율과 버너의 착화 및 연소시의 화염안정성을 증가시켜 에너지절감을 도모할 수 있도록 되어 있다.2 is an internal cross-sectional view showing the boiler structure of the waste heat recovery of the present invention, the present invention is different from the prior art by separating the blower 5 and the burner head 6 from the air supply hose (7) of the tubular body (1) By collecting the heat exiting the exhaust gas through the noise chamber (4) and blowing it to the blower (5) to use as combustion air in the burner head (6) by increasing the thermal efficiency and burn stability of the burner and flame stability during combustion The savings can be planned.

상기 관체(1)에는 하단부로 연소실(2)이, 이 연소실(2)위로 연관(3)을 통해 소음통(4)이 각각 설치되는 바, 이 연관(3)에는 버플이 형성되어 있어 상기 연소실(2)에서의 연료연소시 발생되는 배기가스를 상기 소음통(4)으로 배출된다.The tube 1 is provided with a combustion chamber 2 at its lower end, and a noise chamber 4 is installed through the tube 3 above the combustion chamber 2, and a buckle is formed in the tube 3 so that the combustion chamber is provided. Exhaust gas generated at the time of fuel combustion in (2) is discharged to the noise chamber (4).

상기 소음통(4)의 열교환부에서 송풍기(5)가, 급기호스(7)를 통해 버너헤드부(6)가 각각 설치되어 상기 버너헤드부(6)의 공기가 더 정류된 공기유로인 것이다.The blower 5 is installed in the heat exchange part of the noise chamber 4, and the burner head part 6 is installed through the air supply hose 7 so that the air of the burner head part 6 is further rectified. .

상기 버너헤드부(6)에는 보염판(8), 전극봉(9) 및 노즐대(10)로 구성되어 연료와 따뜻한 공기가 유입되고 있다.The burner head portion 6 is composed of a flame plate 8, an electrode rod 9, and a nozzle stand 10, and fuel and warm air are introduced therein.

따라서, 상기 소음통(4)의 열교환부에서는 모터 및 팬으로 된 송풍기(5)로부터의 찬공기가 배기가스와 열교환되어 따뜻한 공기를 급기호스(7)를 통해 버너헤드부(6)로 보내어 버너의 연소를 촉진시켜 열효율을 상승시킨다.Therefore, in the heat exchange part of the noise chamber 4, cold air from the blower 5, which is a motor and a fan, exchanges heat with the exhaust gas, and sends warm air to the burner head part 6 through the air supply hose 7 to the burner. It promotes combustion and raises thermal efficiency.

그러므로, 송풍기(5)의 팬과 버너헤드부(6)사이와 공기유로는 길어질수록 정류가 잘된다는 것을 이용하여 유속 및 유량이 일정하므로 연소가 잘될 뿐만 아니라 화염이 안정되어진다.Therefore, since the flow rate and flow rate are constant between the fan and the burner head part 6 of the blower 5 and the air flow path becomes longer, the combustion is good and the flame is stabilized.

제3도는 본 고안의 폐열회수의 보일러구조를 설명하기 위한 상태도로서, 본 고안은 종래의 일체화된 버너헤드부와 송풍기가 소음통에서 배기가스와 열교환된 공기를 열흡입하는 구조로부터 송풍기(5)와 버너헤드부(6)를 분리하므로, 연소공기를 소음통(4)으로 밀어내어 열교환시킨 공기를 버너헤드부(6)로 보내어 밀어내는 형태의 공기흐름을 가진 버너를 부착한 보일러인 것이다.3 is a state diagram for explaining the boiler structure of the waste heat recovery of the present invention, the present invention is a blower (5) from the structure that the conventional integrated burner head portion and the blower heat intake air heat exchanged with the exhaust gas in the noise chamber Since the burner head part 6 is separated from the burner head 6, the burner having a burner having an air flow in which the combustion air is pushed into the noise chamber 4 and heat-exchanged is sent to the burner head part 6.

즉, 상기 송풍기(5)와 버너헤드부(6)를 분리시켜 송풍기(5)에서 토출된 공기가 열교환부에서 열교환되어 급기호스(7)를 통해 버너헤드부(6)안으로 들어가게 함으로써 폐열을 이용할 수 있는 온도를 종래보다 상승시켜 열효율을 더욱 증가시킬 수 있다.That is, by separating the blower 5 and the burner head 6, the air discharged from the blower 5 is heat-exchanged in the heat exchanger to enter the burner head 6 through the air supply hose 7 to utilize waste heat. By increasing the temperature can be increased than conventional thermal efficiency.

그러면, 상기 버너헤드부(6)의 공기도 종래 버너의 유로보다도 더욱 정류된 공기유로이므로, 상기 송풍기(5)의 팬과 버너헤드부(6)까지의 거리를 증가시키며 유로가 형성되어 화염의 안정성 및 착화가 더 잘된다.Then, since the air of the burner head part 6 is also an air flow path which is further rectified than the flow path of the conventional burner, the flow path is formed by increasing the distance between the fan of the blower 5 and the burner head part 6, and the Better stability and ignition

따라서, 본 고안은 열효율과 버너의 착화, 연소시의 화염안정성을 증가시킴으로써 에너지 절감 및 환경에 대한 걱정을 줄일 수 있는 잇점이 있다.Therefore, the present invention has the advantage of reducing energy savings and environmental concerns by increasing thermal efficiency, burner ignition, and flame stability during combustion.

이상 설명한 바와 같이 본 고안에 의하면, 송풍기와 버너헤드부를 분리시켜 연소용 공기온도를 상승시켜 연소성을 좋게하고, 연소공기로 따뜻한 공기를 이용하므로 열효율을 상승시켜 에너지를 절감할 수 있고, 연료를 절약하므로 환경오염에 도움을 주고 있으며, 화염이 안정적이므로 착화 및 연소성을 증가시킬 수 있다.As described above, according to the present invention, the blower and the burner head part are separated to increase combustion air temperature to improve combustibility, and since warm air is used as combustion air, thermal efficiency can be increased to save energy and save fuel. Therefore, it helps to environmental pollution, and because the flame is stable, it can increase the ignition and combustibility.
