본 고안은 보조 연소대를 갖는 개탄보일러에 관한 것으로, 특히 연소대에서 가열관으로 바로 빠져나가는 내부 통기를 연소실로 유도하여 개탄보일러의 열효율을 향상하도록 하는 보조연소대를 갖는 개탄보일러에 관한 것이다.The present invention relates to a charcoal boiler having an auxiliary combustion zone, and more particularly, to a coal boiler having an auxiliary combustion zone to guide the internal aeration directly exiting the heating tube from the combustion zone to the combustion chamber to improve the thermal efficiency of the coal boiler.

일반적으로 고체연료용 보일러는 석탄,개탄, 조개탄 또는 나무 등을 연료로 이용하는 보일러이다. 그 중 개탄(또는 괴탄)은 석탄 중에서 가장 탄화도가 낮은 것으로, 전체 석탄 매장량 중 45% 정도가 개탄일 정도로 매장량이 풍부하며 가격 또한 저렴하다. 따라서, 개탄를 연료로 하는 난방기구가 널리 사용되고 있다.Generally, solid fuel boilers are coal, coal, coal briquettes, or wood. Among them, coal (or lump coal) is the lowest carbon among the coal, and 45% of the coal reserves are coal, which is rich in reserves and low in price. Therefore, a heating mechanism using charcoal as a fuel is widely used.

도 1은 종래의 개탄보일러를 나타내는 단면도이며, 도 1에 예시된 개탄보일러(등록번호 : 20-0344859)는 투입구(E)로 개탄을 투입하여 로스톨(6)에서 점화를 하게되면 초기에 많은 연기가 발생되게되고, 이때 발생하는 연기는 연소통(2)의 배기구(201)와 외통(1)의 배기구(101)를 직결되게 열어 연기가 바로 방출될수 있게 하고, 그 후 어느 정도 점화가 이루어져 화력이 발생하면 연소실(A)의 배기구(201)는 닫고 그 열을 연소대(5)측방으로 회열하여 가열실(B)을 가열하게 되며, 이때 가열실(B)에는 연소통(2)을 감싸고 있는 온수파이프(3)를 중점적으로 가열하게되고, 내부의 통기는 연소통(2)과 외통(1)사이에 배치된 다수개의 가열관(4)으로 소극적으로 빠져나가 외통(1)의 배기실(C)을 통해 배출되게 되는 것이다.1 is a cross-sectional view showing a conventional coal boiler, the coal boiler (registered number: 20-0344859) illustrated in FIG. 1 is a lot of initially in the case of ignition in the rostol (6) by inputting the coal to the inlet (E) Smoke is generated, and the smoke generated at this time is directly connected to the exhaust port 201 of the combustion cylinder 2 and the exhaust port 101 of the outer cylinder 1 so that the smoke can be immediately released, and after that, the ignition is made to some extent. When the thermal power is generated, the exhaust port 201 of the combustion chamber A is closed and the heat is returned to the combustion table 5 side to heat the heating chamber B. At this time, the combustion chamber 2 is placed in the heating chamber B. The heated hot water pipe 3 is mainly heated, and the aeration inside is passively exited by a plurality of heating tubes 4 disposed between the combustion cylinder 2 and the outer cylinder 1 to exhaust the outer cylinder 1. It is to be discharged through the seal (C).

그러나 상기 가열관으로 빠져나가는 내부의 통기 중 일부는 연소대에서 연소실이나 가열실을 통하기 않고 바로 빠져나가므로, 그 만큼 온수파이프를 가열하는 열이 저감된다. However, since some of the internal aeration flows out into the heating tube immediately exits from the combustion zone without passing through the combustion chamber or the heating chamber, the heat for heating the hot water pipe is reduced by that much.

즉, 상술한 바와같이 가열관으로 바로 빠져나가는 내부공기에 비례한 만큼 열손실이 발생되는 문제점이 있었다.That is, as described above, there is a problem in that heat loss occurs in proportion to the internal air immediately exiting the heating tube.

따라서 본 고안은 이와같은 문제점을 감아하여 안출한 것으로써, 좀더 자세하게는 연소대에서 가열관으로 바로 빠져나가는 내부 통기를 차단하여 개탄보일러의 열효율을 향상하도록 하는 개탄보일러의 보조연소대를 제공하는 것을 목적으로 한다.Therefore, the present invention has been devised to wind up such a problem, more specifically, to provide an auxiliary combustion unit of a coal boiler to improve the thermal efficiency of the coal boiler by blocking the internal aeration directly exiting from the combustion zone to the heating tube. The purpose.

이와같은 목적을 달성하기 위하여 본 고안은 상측에 배기실을 갖는 외통과, 상기 외통의 내측에 형성된 연소대와, 상기 연소대의 상측으로 일정간격 이격되여 연소실을 형성한 내통과, 상기 내통의 외측으로 상단이 막힌 가열실 및 연소실과 배기실로 상하단이 개방된 다수의 가열관을 구비한 개탄보일러에 있어서, 상기 연소대에 입설되여 연소대와 연소실을 연통하는 보조연소대를 더 구비하는 것을 특징으로 하는 보조연소대를 갖춘 개탄보일러를 제공한다.In order to achieve the above object, the present invention provides an outer cylinder having an exhaust chamber on the upper side, a combustion table formed inside the outer cylinder, an inner cylinder formed at a predetermined interval apart from the upper side of the combustion chamber to form a combustion chamber, and an outer side of the inner cylinder. In the coal fired boiler having a heating chamber of which the upper end is blocked, and a plurality of heating tubes whose upper and lower ends are opened to the combustion chamber and the exhaust chamber, further comprising an auxiliary combustion zone which is installed in the combustion zone and communicates the combustion zone and the combustion chamber. Provide coal fired boilers with auxiliary combustion units.

본 고안의 구성 및 실시예를 첨부된 도 2, 3를 참조하여 자세하게 살펴보면 다음과 같다.Looking at the configuration and the embodiment of the present invention in detail with reference to the attached 2, 3 as follows.

먼저 본 고안의 자세한 설명에 있어서, 보조연소대를 제외한 개탄보일러는 종래 설명한 부분과 동일하므로 그 설명을 배제하고, 보조연소대에 관한 자세한 설명으로 국한 하며, 또한 도면부호도 종래와 동일하게 사용한다.First of all, in the detailed description of the present invention, the coal boiler except for the auxiliary combustion unit is the same as the previously described part, and the description thereof is omitted, and the description is limited to the detailed description of the auxiliary combustion unit. .

도 2는 본 고안을 나타내는 단면도이고, 도 3은 본 고안에 따른 보조연소대를 나타내는 사시도이다.2 is a cross-sectional view showing the present invention, Figure 3 is a perspective view showing a secondary combustion zone according to the present invention.

본 고안의 구성은 상측에 배기실(C)을 갖는 외통(1)과, 상기 외통의 내측에 형성된 연소대(5)와, 상기 연소대의 상측으로 일정간격 이격되여 연소실(A)을 형성한 내통(2)과, 상기 내통의 외측으로 상단이 막힌 가열실(B) 및 연소실(A)과 배기실(C)로 상하단이 개방된 다수의 가열관(4)을 구비한 개탄보일러에 있어서, 상기 연소대(5)에 입설되여 연소대(5)와 연소실(A)을 연통하는 보조연소대(50)를 더 구 비한 것이다.The constitution of the present invention is an inner cylinder 1 having an exhaust chamber C on the upper side, a combustion table 5 formed inside the outer cylinder, and an inner cylinder spaced at a predetermined interval above the combustion chamber to form a combustion chamber A. (2) and a coal fired boiler having a heating chamber (B) having an upper end blocked outside of the inner cylinder, and a plurality of heating tubes (4) whose upper and lower ends are opened to the combustion chamber (A) and the exhaust chamber (C). The auxiliary combustion zone (50) installed in the combustion zone (5) and communicating with the combustion zone (5) and the combustion chamber (A) is further provided.

이를 좀 더 자세하게 설명하면 상기 보조연소대(50)의 상단이 일정길이 연소실(A)에 삽입되도록 한다. 따라서 상기 상기 보조연소대(50)의 외경은 연소실(A)의 내경보다 다소 작게 형성하며, 이때, 상기 보조연소대(50)의 외경과 연소실(A)의 내경 사이로 개탄의 입자가 유입되지 않도록 고려하여 보조연소대(50)의 외경을 형성함이 바람직하다.In more detail, the upper end of the auxiliary combustion zone 50 is inserted into the combustion chamber A for a predetermined length. Therefore, the outer diameter of the auxiliary combustion zone 50 is formed to be somewhat smaller than the inner diameter of the combustion chamber (A), at this time, so that the particles of charcoal do not flow between the outer diameter of the auxiliary combustion zone (50) and the inner diameter of the combustion chamber (A). It is preferable to form the outer diameter of the auxiliary combustion zone (50) in consideration.

또한, 상기 보조연소대(50)는 주철재질의 주물제품으로 내경부에는 다수의 홈(51)을 형성하여 그 표면적을 확대하므로써, 개탄의 연소열이 전도되는 표면의 향상으로 따른 열흡수율을 향상한다.In addition, the auxiliary combustion zone (50) is a cast iron casting product formed by forming a plurality of grooves 51 in the inner diameter portion to increase the surface area, thereby improving the heat absorption rate due to the improvement of the surface conducting the heat of combustion of coal coal. .

이와같은 본 고안의 실시예를 살펴보면 다음과 같다.Looking at such an embodiment of the present invention as follows.

투입구(E)로 개탄을 투입하여 로스톨(6)에서 점화를 하게되면 초기에 많은 연기가 발생되게되고, 이때 발생하는 연기는 연소통(2)의 배기구(201)와 외통(1)의 배기구(101)를 직결되게 열어 연기가 바로 방출될수 있게 하고, 그 후 어느 정도 점화가 이루어져 화력이 발생하면 연소실(A)의 배기구(201)는 닫고 그 열은 보조연소대(50)에 의하여 전부가 연소실(A)로 유입되여, 내통(2)의 외측에 감취된 온수파이프(3)를 일차적으로 가열하고 후, 보조연소대(50)와 가열실 사이의 틈새로 빠져나와서 연소대(5)측방으로 회열하여 가열실(B)을 가열하게 되며, 이때 가열실(B)에는 연소통(2)을 감싸고 있는 온수파이프(3)를 중점적으로 이차적으로 가열하게되고, 이후, 내부의 통기는 연소통(2)과 외통(1)사이에 배치된 다수개의 가열관(4)으로 빠져나가 외통(1)의 배기실(C)을 통해 배출되게 되는 것이다.When the coal is injected into the inlet (E) and ignited in the rostol (6), a lot of smoke is generated initially, and the generated smoke is exhaust port 201 of the combustion cylinder 2 and exhaust port of the outer cylinder 1. Directly open the 101 to allow the smoke to be discharged immediately, and if the ignition occurs to some extent after the fire occurs, the exhaust port 201 of the combustion chamber (A) is closed and the heat is entirely by the auxiliary combustion zone (50) After flowing into the combustion chamber A, the hot water pipe 3 concealed on the outside of the inner cylinder 2 is primarily heated, and then exits into the gap between the auxiliary combustion zone 50 and the heating chamber to the combustion chamber 5 side. The heating chamber (B) is heated by reheating, and the heating chamber (B) mainly heats the hot water pipe (3) surrounding the combustion cylinder (2). Exit through a plurality of heating tubes (4) disposed between (2) and the outer cylinder (1) through the exhaust chamber (C) of the outer cylinder (1) Will be discharged.

이상에서 살펴본 바와같이 본 고안은 연소대에서 발생한 열을 보조연소대가 전부 가열실로 유도하므로써, 보일러의 열효율을 향상하는 효과가 있다.As described above, the present invention has the effect of improving the thermal efficiency of the boiler by inducing all the heat generated from the combustion zone into the heating chamber.

또한, 상기 보조연소대는 개탄의 연소가 끝난 후에도 오래 동안 높은 온도의 자체 잠열을 보유하므로써 연소대를 통하여 유입된 차가운 외부공기에 의하여 내통의 하단이 변형될 수 있는 요인은 미연에 방지하며, 동시에 보일러 내부의 하단에서 더운공기와 차가운 외부공기의 만남으로 인하여 결로현상이 발생하는 것을 미연에 방지할 수 있는 효과가 있다.In addition, the subcombustion zone maintains its own latent heat at a high temperature even after the combustion of the coal is finished, thereby preventing the factor of the lower end of the inner cylinder from being deformed by the cold external air introduced through the combustion zone. There is an effect that can prevent the condensation phenomenon due to the meeting of hot air and cold outside air at the bottom of the inside.
