이하 본 발명에 의한 일실시예의 구성 및 작용을 상세히 설명한다.Hereinafter, the configuration and operation of an embodiment according to the present invention will be described in detail.
도 1은 본 발명의 일실시예에 의한 콘덴싱 기름보일러의 내부구성도이며,1 is an internal configuration diagram of a condensing oil boiler according to an embodiment of the present invention,
도 2는 상기 일실시예에 의한 콘덴싱 기름보일러의 사용상태도이다.2 is a state diagram used in the condensing oil boiler according to the embodiment.
본 콘덴싱 기름보일러는 하향연소하는 버너(10)의 하측에 설치되는 연소실(20)을 구비한다.The condensing oil boiler includes a combustion chamber 20 installed below the burner 10 that is burned downward.
연소실(20)은 원통형상의 주열교환부(31)의 내측에 설치된다.The combustion chamber 20 is provided inside the cylindrical main heat exchanger 31.
주열교환부(31)는 내측에 연소실(20)의 둘레를 따라서 난방수가 저장되고 외측면상부에는 난방수출구가 설치되는 제1수조(33)가 형성된다.The main heat exchange part 31 is provided with a first water tank 33 in which heating water is stored along the circumference of the combustion chamber 20, and a heating export port is installed on the outer surface.
주열교환부(31)의 하측으로는 주열교환부(31)와 일체로 형성되는 부열교환부(32)가 형성된다.Under the main heat exchange part 31, the sub heat exchange part 32 formed integrally with the main heat exchange part 31 is formed.
부열교환부(32)는 내측에 제1수조(33)와 연통되어있으며 외측면하부에는 난방수입구가 설치되는 제2수조(34)가 형성된다.The sub-heat exchange part 32 is in communication with the first water tank 33 in the inner side and the lower side of the outer surface is formed with a second water tank 34 in which the heating inlet is installed.
제2수조(34)는 내측에 연소실(20)과 연통되는 다수개의 연관(40)이 수직방향으로 설치된다.The second water tank 34 is provided with a plurality of pipes 40 communicating with the combustion chamber 20 in the vertical direction.
난방수는 난방수입구를 통하여 서로 연통되어진 제1수조(33) 및 제2수조(34)로 유입되고 아울러 연소실(20) 및 연소실(20)과 연통되어 고온의 배기가스가 통과하는 다수개의 연관(40)의 주위를 순환하여 가열된 후 난방수출구를 통하여 유출된다.The heating water flows into the first and second water tanks 33 and 34 communicated with each other through the heating inlet, and communicates with the combustion chamber 20 and the combustion chamber 20 to pass the high temperature exhaust gas. It is heated by circulating around 40 and then flows out through the heating outlet.
부열교환부(32)는 주열교환부(31)에서 열교환을 마친 배기가스 중에 포함되는 강산성의 응축수와 접하여 부식될 수 있으므로 연관(40)을 포함하여 응축수와 접할수 있는 부위에는 고내식성의 금속재질을 사용한다.Since the sub-heat exchange part 32 may be corroded in contact with the strong acid condensate contained in the exhaust gas after the heat exchange in the main heat exchange part 31, the sub-heat exchange part 32 includes a high corrosion-resistant metal material at the part which may be in contact with the condensate, including the tube 40. use.
또한, 주열교환부(31)에는 급탕입구(81)와 급탕출구(82)가 구비되며 급탕관이 제1수조(33)내에서 연소실(20)의 둘레를 코일형태로 둘러서 이루어지는 급탕열교환기(80)가 설치된다.In addition, the main heat exchanger 31 is provided with a hot water inlet 81 and a hot water outlet 82, the hot water pipe is a hot water heat exchanger formed by surrounding the combustion chamber 20 in the form of a coil in the first water tank 33 ( 80) is installed.
이에, 급탕열교환기(80)는 주열교환부(31)와 열교환하여 급탕용 온수를 공급하게된다.Thus, the hot water supply heat exchanger 80 heats the main heat exchanger 31 to supply hot water for hot water supply.
부열교환부(32)의 하부에는 배기가스 및 배기가스에 포함된 응축수를 이송하는 응축수수집조(50)가 설치된다.The condensate collection tank 50 for transferring the condensate contained in the exhaust gas and the exhaust gas is installed below the sub-heat exchange unit 32.
응축수수집조(50)는 부열교환부(32)의 하부와 결합하는 제1결합구(52), 배기가스를 외부로 배출하는 연도(60)의 하부와 결합되는 제2결합구(53)가 상면에 형성된다. The condensate collection tank 50 includes a first coupler 52 coupled to a lower portion of the sub-heat exchanger 32 and a second coupler 53 coupled to a lower portion of the flue 60 for discharging exhaust gas to the outside. It is formed on the upper surface.
이에, 응축수수집조(50)는 부열교환부(32)측에서 배기가스가 유입되고 내부의 통로를 따라 배기가스를 연도(60)로 이송하게된다.Accordingly, in the condensate collection tank 50, the exhaust gas is introduced from the sub-heat exchanger 32 side, and the exhaust gas is transferred to the flue 60 along the passage therein.
배기가스 중 부열교환부(32)에서 발생된 강산성의 응축수는 수직하방향으로 연관을(40) 따라 응축수수집조(50)에 수집된다.Strongly acidic condensate generated in the sub-heat exchange part 32 of the exhaust gas is collected in the condensate collection tank 50 along the pipe 40 in the vertical downward direction.
강산성의 응축수는 응축수수집조(50)에 수집된 후 경사진 바닥면의 최하부에 형성된 응축수배출구(51)를 통하여 중화처리기(70)로 유입된다.The strongly acidic condensate is collected in the condensate tank 50 and is introduced into the neutralization processor 70 through the condensate outlet 51 formed at the bottom of the inclined bottom surface.
중화처리기(70)는 내부에 중화제가 수납된 중화조를 갖추고 있어 응축수배출구(51)를 통하여 유입된 강산성의 응축수를 중성으로 중화시킨 후, 환경에 무해한 상태로 외부에 배출시키게 된다.The neutralization processor 70 is provided with a neutralization tank in which a neutralizing agent is stored, and neutralizes the strong acid condensed water introduced through the condensate outlet 51 to neutral, and then discharges it to the outside in a state harmless to the environment.
이상과 같이 본 고안의 일실시예에 대해 알아보았으며, 상기 일실시예서 보일러의 안정성 향상을 위해 응축수수집조(50)에는 응축수의 수위를 감지하는 수위감지기(91)를 설치하여 응축수수집조(50)내의 응축수가 사전에 설정된 수위를 초과하여 배기가스 출구인 연도(60)를 막게 됨에 따라 노내압이 상승되는 등의 이상 상태가 발생될 때 이를 감지하여 보일러의 작동을 중지킬 수 있으며, 또한 연도(60)에는 연도(60)내의 배기가스의 온도를 측정하는 과열방지기(92)를 설치하여 보일러 열교환기의 이상에 따른 비정상적인 운전으로 배기가스의 온도가 정상 상태 이상으로 상승하게되면 보일러의 운행을 중지시키는 등의 안전장치를 부가할 수 있다.As described above, the embodiment of the present invention was examined, and in order to improve the stability of the boiler, the condensate tank 50 is installed with a water level detector 91 for detecting the level of condensate. As the condensate in 50) blocks the flue gas outlet 60 which exceeds the preset water level, the boiler can be stopped by detecting an abnormal condition such as an increase in the furnace pressure. The flue 60 is provided with an overheat protector 92 that measures the temperature of the exhaust gas in the flue 60. When the temperature of the exhaust gas rises above the normal state due to abnormal operation according to the abnormality of the boiler heat exchanger, the boiler operates. Safety devices, such as stopping the system, can be added.
상기한 바와 같이 본 발명에 따른 콘덴싱 기름보일러는 하향연소하는 버너의 하측으로 주열교환부와 부열교환부가 일체로 형성되므로 열교환기의 용적을 줄일수 있으며 또한 배기가스 중 강산성의 응축수가 고내식성 금속재질의 부열교환부를 따라 응축수수집조로 유입되므로 강산성의 응축수에 의한 저온부식 등의 문제를 방지할 수 있다는 장점이 있다.As described above, the condensing oil boiler according to the present invention can reduce the volume of the heat exchanger because the main heat exchange part and the sub heat exchange part are integrally formed under the burner which is burned down, and the highly acidic condensed water in the exhaust gas has a high corrosion resistance metal material. Since it flows into the condensate collection tank along the sub-heat exchanger, there is an advantage that it is possible to prevent problems such as low temperature corrosion due to strong acid condensate.
