본 고안은 보일러나 난로등 각종 연소기에 있어서, 연통이 착설되는 부분에 스릿트(Slit)를 형성시키므로서, 연기가 스릿트를 통과할때 스릿트의 상측부에서는 노즐현상으로 유속이 빨라지게되고, 스릿트의 하측부에는 배압(背壓)발생으로 인하여 외기(外氣)를 배연구내로 흡인함과 동시에 연소기내의 바닥면에 정체하는 연탄까스를 흡인하여 신속히 연통으로 배출시키도록 하기위한 것이다.The present invention forms a slit at a portion where communication is installed in various combustors such as a boiler or a stove, and thus the flow velocity is increased by nozzle phenomenon at the upper side of the slit when smoke passes through the slit. In addition, the lower part of the slit is intended to suck out the outside air into the back study due to the occurrence of back pressure and to suck out the briquette cuttled on the bottom surface of the combustor so as to quickly discharge it into communication.
종래의 연소기에 있어서는, 배연구와 연통으로 형성되는 배연통로가 전체적으로 보아 균일한 단면적으로 형성되는 것이었으므로, 배연통로 내에서는 대류작용이나 연기의 유속변화등이 발생되기 힘든 것이었고, 이에 따라 연소기내부에 하향우회식 배연로가 형성된 것에 있어서는 여기가 배연구측으로 하향하는 배연속도가 느리게되므로서 연소효율이 좋지못한 것이었으며, 이를 시정하기 위하여 연통선단부에 배기팬을 착설하여 사용하는 것이 일반적이었다.In the conventional combustor, since the flue gas path formed by the flue gas research and the communication was formed to have a uniform cross-sectional area, convection and smoke flow rate change were difficult to occur in the flue gas path. In the case where the downward bypass type flue gas was formed inside, the combustion efficiency was not good because the flue gas velocity was lowered to the exhaust research side, and it was common to install an exhaust fan at the communication tip to correct this.
본 고안은 이와같은 종래의 실정에 감안하여 배기팬을 착설하지 않고서도, 배연구부분에서 연기의 유속이 빨라지도록하여 보일러내의 연기를 흡인시키므로서 자연적으로 배연작용이 촉진되도록한 것으로서 이하 도면에 따라 본 고안의 실시태양을 상세히 설명하면 다음과 같다.The present invention allows the flow rate of the smoke to be accelerated in the exhaust research section without the installation of the exhaust fan, so that the flue gas is naturally promoted by drawing the smoke in the boiler. An embodiment of the present invention is described in detail as follows.
제1도 내지 제4도에 도시한 것은 연소기(1)의 배연구(2)와 연통(3) 사이를 연결하게된 접속통(4)내에 본 고안을 형성시킨 실시예를 나타내는 것으로서, 접속통(4)의 저면판(5)에는 소구경의 흡기공(6)을 형성하고, 접속통(4)의 유입구(7)내에는 평행하는 수조의 격자봉(8)을 병열설치하여 유입구(7)내에 다수의 스릿트(9)가 형성되도록 구성하여서된 것이다.1 to 4 show an embodiment in which the present invention is formed in the connecting cylinder 4 which connects the exhaust research 2 and the communication 3 of the combustor 1 to the connecting cylinder 3. The inlet hole 6 of the small diameter is formed in the bottom plate 5 of (4), and parallel inlet tank lattice 8 is installed in the inlet port 7 of the connection cylinder 4, and the inlet port 7 Is configured to form a plurality of splits 9).
제5도는 본 고안을 연소기(1)의 배연구에 직접 형성시킨 실시예를 나타낸 것으로서, 스릿트(9)가 연소기(1)의 배연구(2)내에 형성되어 있고, 흡기공(6) 역시 배연구(2)의 저면부에 형성하여, 연통(3)을 연결하도록한 것이다.5 shows an embodiment in which the present invention is directly formed in the exhaust research of the combustor 1, the slit 9 is formed in the exhaust research 2 of the combustor 1, and the intake hole 6 is also It is formed in the bottom part of the embryo study (2), and it connects the communication (3).
또한 제6도 내지 제8도에는 스릿트(9)를 형성시키는 각종 실시예가 도시되어 있는바, 제6도에 도시한 것은 격자봉(8)을 3각형으로 형성하여 스릿트(9)로 향하는 연기의 진입구를 넓게 형성한 것이고, 제7도에 도시한 것은 스릿트(9)를 상방으로 갈수록 좁게 형성하여 스릿트(9)의 상측부에서의 배연유속이 보다 빨라지도록한 것이고, 제8도에 도시한 것은 스릿트(9)를 배연료의 상측부에만 형성하고, 하측부는 통상의 개방통로로 형성한 것이다.6 to 8 illustrate various embodiments of forming the slit 9, which is shown in FIG. 6 to form a triangular bar 8 in a triangular shape and directed toward the slit 9. The opening of the smoke is wider, and the one shown in FIG. 7 is to narrow the slit 9 upwards so that the flue gas velocity at the upper side of the slit 9 becomes faster, and FIG. In the figure, the slit 9 is formed only in the upper part of the flue fuel, and the lower part is formed in a normal open passage.
또한 스릿트(9)는 경우에 따라 수평방향으로 형성할 수 있는 것이며, 흡기공(6)은 스릿트(9)보다 하방으로 위치하도록 적당한 개소에 형성시킬 수 있는 것이다.In addition, the slit 9 can be formed in a horizontal direction depending on the case, and the intake hole 6 can be formed in a suitable location so that it may be located below the slit 9.
이와같이 구성된 본 고안은 연소기(1)의 배연구(2)측에 스릿트(9)가 형성되어 있는 것이므로 연소기(1) 내부에서 배연구(2)측으로 배연되는 고온의 연기는 연통(3) 측으로 상승하면서 스릿트(9)를 통과하게되는 것이나, 연기가 스릿트(9)를 통과할때에는 제4도 및 제5도에 도시한 바와같이 연기는 고온상태이므로 수직으로 형성된 스릿트(9)의 상측부를 통과하게되는 것이고, 이에따라 스릿트(9)의 상측부에서는 노즐현상으로 인한 축류(縮流)현상이 발생하여 스릿트(9)를 통과하는 연기의 유속이 빨라지게되고, 한편 스릿트(9)의 하측부에는 압력이 낮은 배압(背壓)이 발생하게되므로서 흡기공(6)으로부터 유입하는 외기가 압력이 낮은 스릿트(9)의 하측부로 흡입되면서 다시 상승기류로 변하여 연기와 함께 연통(3)내로 상승하게되는 것이다. 이때 연통(3)내로 유입되는 연기의 일부는 스릿트(9) 하방에 형성된 압력이 낮은 배압발생부로 향하여 하강하게되면서 스릿트(9)후방에는 와류가 발생하게되는 것이고, 와류의 중심부에는 감압부가 형성되므로서 스릿트(9)의 하측부에 발생된 저압의 배압부와 함께 연소기(1) 내부의 연기를 접속통(4)내로 흡인하게되는 것이다.Since the present invention configured as described above has a slit 9 formed on the exhaust research 2 side of the combustor 1, the high-temperature smoke exhausted from the combustor 1 to the exhaust research 2 side is connected to the communication 3 side. As it rises, it passes through the split 9, but when the smoke passes through the split 9, as shown in FIGS. 4 and 5, the smoke is in a high temperature state, As a result, an axial flow phenomenon due to the nozzle phenomenon occurs at the upper side of the slit 9, so that the flow velocity of the smoke passing through the slit 9 is increased, while the slit ( In the lower part of 9), a low pressure back pressure is generated, and the outside air flowing from the intake hole 6 is sucked into the lower part of the slit 9 where the pressure is low, and then turns into an upward airflow, together with the smoke. It will rise into the communication (3). At this time, a part of the smoke flowing into the communication (3) is lowered toward the low pressure back pressure generating portion formed under the rit (9), the vortex is generated behind the rit (9), the decompression unit in the center of the vortex As a result, the smoke inside the combustor 1 is sucked into the connecting cylinder 4 together with the low pressure back pressure generated in the lower part of the slit 9.
따라서 연소기(1) 내부에 정체하는 연탄까스 까지도 용이하게 접속통(4)내로 흡인하여 연기와 함께 연통(3)으로 배출시키므로서 배연작용을 촉진하여 연소효율을 향상시키게되는 작용효과를 나타내게 되는 것이다.Therefore, even the briquette cuttled in the combustor 1 is easily sucked into the connection tube 4 and discharged into the communication tube 3 with the smoke, thereby promoting the flue-gas effect and improving the combustion efficiency. .
