상기한 목적을 달성하기 위하여 본 고안에 따른 보일러는 연소실에서 연료를 연소시켜 상측의 연도들을 통해 배출되는 연소가스로부터 연소열을 회수하여 물을 가열시키도록 연소실과 연도 외측 주변에 수조가 형성된 보일러로서, 상기 연소실의 연도를 상측의 절반 영역에 형성하여 이차연소실로 연통되게 하고, 나머지 절반영역에는 배출되는 연소가스의 체류시간을 연장시키도록 상기 이차연소실로부터의 연소가스가 반대방향으로 유동되어 배출되도록 통로가 복수개 형성되고 외측에 수조가 형성된 3차연소실조립체가 제공된 것을 특징으로 하여 구성된다.In order to achieve the above object, a boiler according to the present invention is a boiler in which a water tank is formed around a combustion chamber and outside of a flue to heat water by recovering combustion heat from combustion gas discharged through upper flues by burning fuel in a combustion chamber, The flue of the combustion chamber is formed in the upper half of the combustion chamber to communicate with the secondary combustion chamber, and in the other half of the combustion chamber, the combustion gas from the secondary combustion chamber flows and flows in the opposite direction to extend the residence time of the discharged combustion gas. It is characterized in that a plurality of the third combustion chamber assembly is provided with a water tank formed on the outside is provided.

이하에서는 본 고안의 실시예를 도시한 첨부된 도면을 참고하여 본 고안의 보일러를 보다 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings showing an embodiment of the present invention will be described in more detail the boiler of the present invention.

도 2는 본 고안에 의한 보일러(10)의 구조를 단면도로 보여주고 있으며, 도면에 도시되지 않았지만 화구에 연결된 버너에 의해 분사되는 경유등의 연료가 연소실(11)에서 연소되고, 그 상측의 절반의 영역에 복수개의 연도(12)가 형성되고, 보일러 상측에는 연도(12)들을 통해 배출되는 연소가스를 체류시켜 이차연소가 이루어지도록 하는 이차연소실(13)이 형성되어 있고, 연소실(11) 상측의 나머지 절반의 영역에는 도 3에서 점선으로 표시된 바와같이 본 고안에 따른 3차 연소실조립체(14)가 제공된다.2 is a cross-sectional view of the structure of the boiler 10 according to the present invention. Although not shown in the drawing, fuel such as diesel fuel injected by a burner connected to a fireball is burned in the combustion chamber 11, and the upper half of the fuel 10 is burned. A plurality of flues 12 are formed in the region of the combustion chamber, and a secondary combustion chamber 13 is formed in the upper portion of the boiler to maintain the combustion gas discharged through the flues 12 so as to perform secondary combustion. In the other half of the region, a tertiary combustion chamber assembly 14 according to the present invention is provided as indicated by the dashed line in FIG. 3.

본 고안에 따른 3차 연소실조립체(14)는 도 4에 도시된 바와같이 반원기둥 형태로서 상하로 연소가스 통로(15)가 복수개 형성되어 연도로서 작용하도록 이차 연소실과 연통되고, 하측에 연소가스 배출구(16)가 형성된 구조로 이루어져 있다.The third combustion chamber assembly 14 according to the present invention has a plurality of combustion gas passages 15 formed up and down in a semi-cylindrical shape as shown in FIG. 4 so as to communicate with the secondary combustion chamber so as to act as a flue, and a combustion gas outlet at the lower side. It consists of the structure in which (16) was formed.

상기 연소실(11)의 외측과 연도(12) 및 이차연소실(13)의 상측과 주변 및 3차 연소실 조립체(14)의 연소가스 통로(15)들 사이의 공간(20)은 수조를 이루어 난방을 위한 물이 채워져 있어서 연소실 및 연도와 통로들을 통하여 연소가스와의 열교환에 의해 가열됨으로써 난방용으로 사용되도록 이루어져 있다.The space 20 between the outside of the combustion chamber 11 and the flue 12, the upper side of the secondary combustion chamber 13 and the surroundings and the combustion gas passages 15 of the tertiary combustion chamber assembly 14 forms a water tank to provide heating. It is filled with water to be used for heating by heating by heat exchange with the combustion gas through the combustion chamber and flue and passages.

본 고안에 따라 3차 연소실조립체(14)를 보일러 연소실 상측의 절반의 영역에 설치함으로써, 연소실(11)에서 연료가 연소될 때 발생되는 연소열에 의해 이차적으로 연소실 외측 주변에 형성된 수조(21)의 물을 가열시키게 되고, 연소가스가 연도(12)를 통하여 이차연소실(13)로 유입된다.According to the present invention, by installing the tertiary combustion chamber assembly 14 in the half region of the upper side of the boiler combustion chamber, the tank 21 formed around the outer side of the combustion chamber by secondary combustion heat generated when the fuel is combusted in the combustion chamber 11. The water is heated, and the combustion gas flows into the secondary combustion chamber 13 through the flue 12.

그런 다음 이차연소실(13)의 연소가스는 3차 연소실 조립체(14)의 통로(15)를 통하여 유동하게 되는데, 이때의 유동방향은 연소실(11)로 부터의 연도를 통해 배출되는 방향과 반대로 이루어져 있어서 결과적으로 연소가스의 유동 경로가 연장되는 효과가 있게 됨과 함께 연소가스의 유동 속도가 늦어지게 됨으로써 결과적으로 연소가스 유동 통로(15)를 통해 배출되는 연소가스의 체류시간이 연장되고, 따라서 유동 통로(15) 외측의 수조의 물과 열교환가능한 시간이 연장되어 배출되는 연소가스로부터의 열회수가 효율적으로 이루어짐과 함께 연소가스가 완전 연소되므로 배출되는 배기가스로 인한 오염물질의 발생이 저하되어 친환경적이다.The combustion gas of the secondary combustion chamber 13 then flows through the passage 15 of the tertiary combustion chamber assembly 14, where the flow direction is opposite to the direction of discharge through the flue from the combustion chamber 11. As a result, the flow path of the combustion gas is extended, and the flow rate of the combustion gas is slowed. As a result, the residence time of the combustion gas discharged through the combustion gas flow passage 15 is extended. (15) The heat recovery from the combustion gas discharged by the extended heat exchange time with the water in the outside of the water is carried out efficiently, and since the combustion gas is completely burned, the generation of pollutants due to the discharged exhaust gas is reduced, which is environmentally friendly.

도면에서, 부호 30으로 표시된 것은 수조로 물이 유입되는 유입구이며, 부호 31은 수조내에서 가열된 물이 상승되어 난방을 위하여 배출되는 배출구이다. 또한, 수조내에는 급탕코일(32)이 제공되어 본 고안의 보일러를 난방용 보일러로 사용하는 경우에 수조내의 온수는 난방을 위해 계속적으로 순환되지만, 급탕코일(32)에 공급되는 물은 간접가열되어 사용자가 온수를 음료용 또는 다른 용도로 이용할 수 있도록 한다. 또한, 부호 32는 투시창으로서 연소실(11) 내부를 볼 수 있어서 연료의 연소가 잘 이루어지는지를 사용자가 확인할 수 있도록 한다.In the figure, denoted by reference numeral 30 is an inlet through which water is introduced into the tank, and reference numeral 31 denotes an outlet through which the heated water in the tank is raised and discharged for heating. In addition, the hot water supply coil 32 is provided in the water tank so that when the boiler of the present invention is used as a heating boiler, the hot water in the water tank is continuously circulated for heating, but the water supplied to the hot water coil 32 is indirectly heated. Allow the user to use hot water for drinks or other purposes. Further, reference numeral 32 denotes a viewing window so that the inside of the combustion chamber 11 can be seen so that the user can check whether the combustion of the fuel is performed well.

본 고안에 따라, 연소실에서 배출되는 연소가스의 이차연소실에 연소가스 배출 통로가 연결되는 3차연소실조립체를 설치함으로써 보일러 연소실의 연소가스의 유동 경로를 연장시키고 연소가스의 보일러내의 체류시간을 연장시켜 이차연소실과 3차연소실 및 연도를 통한 연소가스로부터의 연소열 회수 시간이 연장됨으로써 연소 에너지 회수 효율을 향상시킴으로써 에너지 절약 효과가 있고, 기존의 보일러에도 간편하게 적용할 수 있는 장점이 있으며, 연소가스의 체류시간 연장으로 연소가스에 함유된 오염발생 물질이 연소되어 배출되는 환경오염물질의 량을 감소시키는 친환경적인 장점이 있다.According to the present invention, by installing a third combustion chamber assembly in which the combustion gas discharge passage is connected to the secondary combustion chamber of the combustion gas discharged from the combustion chamber to extend the flow path of the combustion gas in the boiler combustion chamber and to extend the residence time of the combustion gas in the boiler By extending combustion heat recovery time from combustion gas through secondary combustion chamber and tertiary combustion chamber and flue, it is possible to save energy by improving combustion energy recovery efficiency, and it can be easily applied to existing boilers. There is an environmentally friendly advantage of reducing the amount of environmental pollutants emitted by the combustion of pollutants contained in the combustion gas by prolonged time.
