Description

급기예열실이 구비된 보일러Boiler with air supply preheating chamber
본 발명은 급기예열실이 구비된 보일러에 관한 것으로서, 더욱 상세하게는 외부에서 급기되는 공기가 연소실의 일측에 구비된 급기예열실에서 예열된 후에 버너로 공급되도록 함으로써 버너의 연소성을 향상시킴과 동시에 연소실 커버를 통하여 외기로 손실되는 에너지를 최소화함으로써 보일러의 열효율을 향상시킬 수 있도록 하는 급기예열실이 구비된 보일러에 관한 것이다.The present invention relates to a boiler having an air supply preheating chamber. More specifically, the air supplied from the outside is supplied to the burner after being preheated in the air supply preheating chamber provided at one side of the combustion chamber, thereby improving burnability of the burner. The present invention relates to a boiler having an air supply preheating chamber which can improve the thermal efficiency of a boiler by minimizing energy lost to outside air through a combustion chamber cover.
일반 가정의 난방 및 급탕 설비로 널리 보급되어 사용되고 있는 보일러는, 난방수를 가열하는 사용 연료와 열원 및 버너의 위치 등 여러 기준에 따라 분류되고 있다. 즉, 사용 연료에 따라서는 기름보일러와 가스보일러로 구분되는데, 기름보일러는 경유 또는 등유를 연료로 사용하며, 가스보일러는 액화석유가스(LPG)나 액화천연가스(LNG)를 연료로 사용한다.BACKGROUND ART Boilers, which are widely used for heating and hot water supply facilities in general households, are classified according to various criteria such as the fuel used to heat the heating water, the location of heat sources and burners. That is, depending on the fuel used, it is divided into an oil boiler and a gas boiler. The oil boiler uses light oil or kerosene as fuel, and the gas boiler uses LPG or LPG as fuel.
상기와 같은 보일러의 유형 중, 도 1은 종래 기름보일러의 일례를 나타낸 것이다. 종래 기름보일러는, 외부 공기를 흡입하여 공급하는 송풍기(1), 상기 송풍기(1)로부터 공급된 공기와 연료의 혼합물을 연소하는 버너(2), 상기 버너(2)에 의한 연소가 이루어지는 연소실(3), 상기 연소실(3)에서 생성된 연소생성물의 유로를 형성하는 연관(4), 상기 연소실(3)의 일측면을 형성하며 버너(2)가 설치되는 연소실 커버(5), 상기 연소실(3) 둘레에 구비되고 내부에는 난방수가 수용되며 난방수유입구(6a)와 난방수배출구(6b)가 형성된 수조(6), 열교환을 마친 연소생성물이 모이는 배기후드(7) 및 상기 배기후드(7)에 연통되어 연소생성물이 외부로 배출되는 연도(8)를 포함한다.Among the types of boilers as described above, Figure 1 shows an example of a conventional oil boiler. The conventional oil boiler has a blower (1) for sucking and supplying external air, a burner (2) for burning a mixture of air and fuel supplied from the blower (1), and a combustion chamber in which combustion by the burner (2) is performed ( 3) an association 4 for forming a flow path of the combustion product generated in the combustion chamber 3, a combustion chamber cover 5 that forms one side of the combustion chamber 3, and a burner 2 is installed, and the combustion chamber ( 3) A water tank 6 provided with a circumference and having a heating water therein and having a heating water inlet 6a and a heating water outlet 6b, an exhaust hood 7 and a exhaust hood 7 in which the heat exchanged combustion products are collected. And flue 8 in communication with the combustion product is discharged to the outside.
상기와 같이 구성된 기름보일러에서, 외부 공기는 송풍기(1)로 흡입되어 버너(2)에 곧바로 공급되며, 상기 버너(2)는 급기된 공기와 연료에 화염을 발생시켜 연소실(3) 내부에 고온의 연소생성물을 만들고, 연소실(3)에서 생성된 연소생성물은 연관(4)을 통과하면서 수조(6)에 수용된 난방수에 연소열을 전달한 후에 배기후드(7)로 취합되어 연도(8)를 통해 배출된다.In the oil boiler configured as described above, the outside air is sucked into the blower 1 and immediately supplied to the burner 2, and the burner 2 generates a flame in the air and fuel supplied to the high temperature inside the combustion chamber 3; The combustion product produced in the combustion chamber (3) is passed through the pipe (4), transfers the heat of combustion to the heating water contained in the water tank (6), is collected into the exhaust hood (7) and collected through the flue (8). Discharged.
그리고 상기 수조(6) 내에 수용된 난방수는 연소생성물의 열을 흡수하여 가열된 후에 난방소요처로 공급되거나 온수로 사용된다.And the heating water contained in the water tank (6) is absorbed by the heat of the combustion product is heated and then supplied to the heating source or used as hot water.
이와 같이 구성된 종래 기름보일러는 다음과 같은 문제점이 있다.The conventional oil boiler configured as described above has the following problems.
외부로부터 송풍기(1)로 유입되는 공기의 온도가 낮을 경우에는 차가운 공기가 버너(2)에 직접 공급되므로 연료와 공기의 혼합물의 온도 또한 낮아져 버너(2)의 연소성이 저하되고, 이로 인해 연소생성물의 온도를 원하는 수준의 높은 온도로 형성하기 어려운 문제점이 있다.When the temperature of the air flowing into the blower 1 from the outside is low, since the cool air is directly supplied to the burner 2, the temperature of the mixture of fuel and air is also lowered, which lowers the combustibility of the burner 2, resulting in combustion products. There is a problem that it is difficult to form the temperature at a high temperature of the desired level.
또한 연소실(3)의 일측면을 형성하는 연소실 커버(5)가 외기에 노출되어 있어 연소생성물이 연관(4)에 의해 형성되는 유로를 따라 연소실 커버(5)를 통과하는 과정에서 연소실 커버(5)를 통해 연소생성물의 연소열이 외부로 손실되므로, 손실된 에너지 만큼 수조(6)에 수용된 난방수에 전달되는 에너지가 감소되어 보일러의 열효율이 저하되는 문제점이 있다. 이와 같이 연소실 커버(5)에서의 열손실을 방지하기 위해 연소실 커버(5)에 별도의 단열재를 설치하는 경우를 상정할 수 있으나, 이 경우 보일러의 제작비용이 증가하는 문제점이 있다.In addition, the combustion chamber cover 5 which forms one side of the combustion chamber 3 is exposed to the outside air so that the combustion product covers the combustion chamber cover 5 in the process of passing the combustion chamber cover 5 along the flow path formed by the association 4. Since the heat of combustion of the combustion product is lost through), the energy transmitted to the heating water accommodated in the water tank 6 is reduced by the amount of energy lost, thereby reducing the thermal efficiency of the boiler. As such, it may be assumed that a separate heat insulator is installed in the combustion chamber cover 5 in order to prevent heat loss in the combustion chamber cover 5. However, in this case, a manufacturing cost of the boiler increases.

The air supply preheating chamber 10 has an air supply inlet 11 through which external air flows in one end thereof, and the other end of the air preheated air receives the heat of combustion of the combustion product generated by the combustion of the burner 40. The air supply outlet 12 is formed is discharged, the air supply outlet 12 and the inlet of the blower 30 is communicated by the air supply connection pipe (20).
상기 송풍기(30)는 상기 급기예열실 커버(13)의 외측에 설치된다.The blower 30 is installed outside the air supply preheating chamber cover 13.
상기 버너(40)는 송풍기(30)의 출구에 연통되고, 급기예열실 커버(13)를 관통하여 급기예열실(10)을 가로질러 연소실 커버(52)를 관통하며 연소실(50) 내부로 연장되도록 설치된다.The burner 40 communicates with the outlet of the blower 30, passes through the air supply preheating chamber cover 13, crosses the air supply preheating chamber 10, passes through the combustion chamber cover 52, and extends into the combustion chamber 50. It is installed as possible.
상기 송풍기(30)의 작동에 의해 상기 급기유입구(11)로 유입된 공기는 급기예열실(10)를 통과하면서 연소생성물의 연소열을 전달받아 예열된 후에 상기 급기배출구(12)를 통해 배출되고, 상기 급기배출구(12)에 연결된 급기연결관(20)을 따라 송풍기(30)의 입구로 공급된다. The air introduced into the air supply inlet 11 by the operation of the blower 30 passes through the air supply preheating chamber 10, receives the heat of combustion of the combustion product, and then is preheated and discharged through the air supply outlet 12. It is supplied to the inlet of the blower 30 along the air supply connection pipe 20 connected to the air supply outlet 12.
상기 송풍기(30)의 출구를 통해 배출된 공기는 버너(40)에 공급되어 버너(40)에 공급된 연료와 섞인 혼합물이 버너(40)의 점화에 의해 연소되어 연소실(50) 내부를 향해 화염이 형성되면서 연소생성물이 발생하게 된다.The air discharged through the outlet of the blower 30 is supplied to the burner 40, the mixture mixed with the fuel supplied to the burner 40 is burned by the ignition of the burner 40, the flame toward the interior of the combustion chamber 50 As this is formed, combustion products are generated.
