Field of the Invention The present invention relates to a gas combustion device for a gas boiler, and more particularly, to a gas combustion device for an upward combustion gas boiler, in which a mixed gas from a venturi tube is discharged through a salt hole of an outer cylinder at a uniform pressure, so that combustion is stably performed.

도 1 및 도 2에 도시된 바와 같이, 종래 상향 연소식 가스보일러용 가스연소장치(10)는, 연소실로 노출되는 둘레면에 다수의 염공(11a)이 형성되면서, 상부커버(2)의 내부에 배치되는 둘레면에 벤츄리관(20)의 출구(21)가 연통되는 외통(11)과, 외통(11) 내부에 배치되는 내통(12), 외통(11)의 상하 개구면을 밀폐시키는 상·하부덮개(13,14) 및, 외통(11)의 내부로 혼합가스를 공급하는 벤츄리관(20)으로 이루어지되, 내통(12)의 상하 개구면이 상·하부덮개(13,14)에 각각 고정되어, 외통(11) 내부공간이 내통의 내부공간(A)과, 외통(11)과 내통(12)사이의 공간(B)로 구획되어진 구조로 되어 있다.As shown in FIGS. 1 and 2, the gas combustion apparatus 10 for a conventional upward combustion gas boiler has a plurality of salt holes 11a formed on a circumferential surface exposed to a combustion chamber, and thus, the inside of the upper cover 2. The upper cylinder 11 which the outlet 21 of the venturi tube 20 communicates with the circumferential surface arrange | positioned at the inside, The inner cylinder 12 arrange | positioned inside the outer cylinder 11, and the upper and lower opening surfaces of the outer cylinder 11 are sealed. A lower cover (13,14) and a venturi tube (20) for supplying a mixed gas into the outer cylinder (11), wherein the upper and lower openings of the inner cylinder (12) are provided on the upper and lower covers (13,14). It is fixed, respectively, and the outer cylinder 11 internal space is divided into the inner space A of the inner cylinder, and the space B between the outer cylinder 11 and the inner cylinder 12 is comprised.
이러한 가스연소장치(10)는, 연소실 내부로 공기를 유도하는 공기확산공(4)이 형성되어진 확산판(3)과, 외부로부터 공기가 유입되는 급기구(6)가 형성된 상부커버(2)와 ; 벤츄리관 지지구(1)와 가스연소장치 고정부(9)등이 형성된 하부커버(8)로 이루어진 흡기장치에 설치되며, 또한 상부커버(2)에는 벤츄리관(20)의 입구로 가스를 분사하는 분사노즐(30)이 설치된다.The gas combustion device 10 includes a diffuser plate 3 having an air diffusion hole 4 for inducing air into a combustion chamber, and an upper cover 2 having an air supply port 6 through which air is introduced. Wow ; It is installed in the intake device consisting of a vent cover (1) and a lower cover (8) formed with a gas combustion device fixing part (9), and the upper cover (2) to inject gas into the inlet of the venturi tube (20) The injection nozzle 30 is installed.
따라서, 분사노즐(30)로부터 벤츄리관(20)의 입구로 가스가 분사되면, 급기구(6)로 유입되어진 일부 공기가 분사노즐(30)로부터 분사되어진 가스와 혼합되면서 벤츄리관(20)을 통해서 외통(11)과 내통(12)사이의 공간(B)로 유입되어 내통(12)에 부딪힌 후, 공간(B)로 분포되면서 외통(11)의 염공(11a)을 통해서 연소실(도시안됨)로 분출된다. 이러한 상태에서 점화기구가 작동하게 되면, 염공(11a)을 통해서 연소실로 분출되는 혼합가스가 점화되게 되는데, 이때 급기구(6)로 유입되어진 다른 일부 공기가 확산판(3)의 공기확산공(4)을 통해서 연소실로 유입되므로, 연소실 내의 연소가 촉진된다.그러나, 상기 종래 기술에 따른 가스연소장치(10)는, 벤츄리관(20)의 출구(21)로 유입되는 혼합가스가 내통(12)에 부딪힌 후, 단지 하나의 공간(B)으로 분포되면서 염공(11a)을 통해서 외부로 분출되는 구조를 이루므로, 공간(B)의 압력차가 심하게 발생되어(벤츄리관의 출구주변의 압력이 가장 크고, 벤츄리관으로부터 멀어질수록 압력이 점진적으로 낮아짐), 혼합가스의 연소가 불안정하게 되고, 불완전연소가 증가된다.따라서, 가스연소장치(10)의 기능이 저하되고, 연료의 소비율이 증가되며, 불완전연소량의 증가로 인해서 배기가스중의 유해가스(일산화탄소, 질소산화물 등)의 함량이 증대되는 문제가 발생되었다.Therefore, when gas is injected from the injection nozzle 30 to the inlet of the venturi tube 20, some air introduced into the air supply port 6 is mixed with the gas injected from the injection nozzle 30 and the venturi tube 20 is opened. After entering the space (B) between the outer cylinder 11 and the inner cylinder 12 through the inner cylinder 12, and then distributed into the space (B) through the flame hole (11a) of the outer cylinder 11 (not shown) Is blown out. When the ignition mechanism is operated in such a state, the mixed gas ejected into the combustion chamber through the salt hole 11a is ignited, and at this time, some other air introduced into the air supply mechanism 6 is introduced into the air diffusion hole of the diffusion plate 3 ( 4), combustion in the combustion chamber is promoted through the combustion chamber. However, in the gas combustion device 10 according to the related art, the mixed gas introduced into the outlet 21 of the venturi tube 20 is provided with the inner cylinder 12. After hitting), it is distributed in only one space (B) and forms a structure that is ejected to the outside through the salt hole (11a), the pressure difference of the space (B) is severely generated (the pressure around the outlet of the venturi tube is the most The larger, the further away from the venturi tube, the lower the pressure is), the combustion of the mixed gas becomes unstable and the incomplete combustion is increased. Thus, the function of the gas combustion device 10 is deteriorated and the fuel consumption rate is increased. Incomplete combustion Due to the increase, the content of harmful gases (carbon monoxide, nitrogen oxides, etc.) in the exhaust gas increases.
이에 본 발명은 상기와 같은 문제를 해결하기 위해 발명된 것으로, 벤츄리관으로부터의 혼합가스가 균일한 압력으로 외통의 염공을 통해서 배출되도록 하여, 연소가 안정적으로 이루어지고, 연료의 연소율이 향상되며, 불완전연소로 인한 유해가스의 발생이 가능한 한 억제되도록 하는 가스보일러용 가스연소장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the above problems, by allowing the mixed gas from the venturi tube to be discharged through the salt hole of the outer cylinder at a uniform pressure, the combustion is made stable, the combustion rate of the fuel is improved, It is an object of the present invention to provide a gas combustion device for a gas boiler to suppress the generation of harmful gases due to incomplete combustion as much as possible.

본 발명에 따른 가스연소장치(10)의 작동상태를 설명해 보면, 분사노즐(30 ; 도 1 참조)로부터 벤츄리관(20)의 입구로 가스가 분사되면, 급기구(6 ; 도 1 참조)로 유입되어진 일부 공기가 분사노즐(30)로부터 분사되어진 가스와 혼합되면서 벤츄리관(20)을 통해서 공간(C)로 유입되고, 공간(C)로 유입된 혼합가스는 외통(11)과 하부덮개(14) 및 격판(15)에 부딪히면서 와류를 형성하며 상호 혼합된 후에, 격판(15)의 내주면에 의한 구멍을 통해서 공간(D)로 유입된다. 공간(D)로 유입된 혼합가스는 상부덮개(13)에 부딪히면서 방사상으로 유동되어 외통(11)의 염공(11a)을 통해서 외부(연소실)로 분출되고, 각 염공(11a)을 통해서 외부로 분출되어진 혼합가스는 점화기구(도시안됨)에 의해 점화되며, 상기 급기구(6)로 유입되어진 다른 일부 공기가 확산판(3)의 공기확산공(4)을 통해서 연소실로 유입되어, 연소실 내의 연소가 촉진된다. 한편, 미설명 부호 '15a'는 공간(C)로부터 공간(D)로 유입되는 혼합가스를 상부덮개(13)로 유도하는 안내날개(15a)이다.Referring to the operating state of the gas combustion device 10 according to the present invention, when gas is injected from the injection nozzle 30 (see Fig. 1) to the inlet of the venturi tube 20, to the air supply (6; see Fig. 1) Some of the introduced air is introduced into the space C through the venturi tube 20 while being mixed with the gas injected from the injection nozzle 30, and the mixed gas introduced into the space C is the outer cylinder 11 and the lower cover ( 14) and after mixing with each other to form a vortex while hitting the diaphragm 15, it enters the space D through the hole by the inner peripheral surface of the diaphragm 15. The mixed gas introduced into the space D flows radially while hitting the upper cover 13, and is ejected to the outside (combustion chamber) through the salt holes 11a of the outer cylinder 11, and is ejected to the outside through the respective salt holes 11a. The mixed gas is ignited by an ignition mechanism (not shown), and some other air introduced into the air supply mechanism 6 flows into the combustion chamber through the air diffusion hole 4 of the diffusion plate 3 and burns in the combustion chamber. Is promoted. On the other hand, reference numeral '15a' is a guide wing (15a) to guide the mixed gas flowing into the space (D) from the space (C) to the upper cover (13).
본 발명에 따르면, 벤츄리관(20)의 출구(21)를 통해서 유입되는 혼합가스가 공간(C)상에서 와류를 형성하면서 1차적으로 상호 재혼합된 후에, 격판(15)의 내주면에 의한 구멍을 통해서 공간(D)로 유입되어, 상부덮개(13)에 중심부분에 부딪히면서 방사상으로 유동되어 2차적으로 재혼합되므로, 공간(D)의 압력이 전체에 걸쳐서 균일화되고, 외통(11)의 염공(11a)을 통해서 외부로 분출되는 혼합가스의 유출량이 균일하게 된다.According to the present invention, after the mixed gas flowing through the outlet 21 of the venturi tube 20 is primarily remixed while forming a vortex in the space C, the hole by the inner peripheral surface of the diaphragm 15 is formed. Through the flow into the space (D), and hitting the central portion in the upper cover 13 radially flows and remixed secondly, the pressure of the space (D) is uniformed throughout, the salt hole of the outer cylinder 11 ( Through 11a), the outflow amount of the mixed gas ejected to the outside becomes uniform.
한편, 상기 벤츄리관(20)의 출구(21)를 공간(C)의 중앙부분에 위치시키고, 출구(21)의 윗쪽 길이보다 출구(21)의 아래쪽 길이가 작아지도록, 출구(21)를 경사지게 하면, 공간(C)에서의 혼합가스의 상호 혼합이 보다 적절하게 수행되는 잇점이 있다.Meanwhile, the outlet 21 of the venturi tube 20 is positioned at the center of the space C, and the outlet 21 is inclined so that the lower length of the outlet 21 is smaller than the upper length of the outlet 21. In other words, there is an advantage that the mutual mixing of the mixed gases in the space C is performed more appropriately.
이상 상기한 바와 같은 본 발명에 따르면, 염공과 벤츄리관 사이에 위치되는 외통의 내부에 환형태의 격판이 구비되어, 외통과 상·하부덮개에 의한 폐공간이 격판을 매개로 상부와 하부로 구분되면서 부분적으로 연통되는 2개의 공간(C,D)으로 구획되어진 구조로 되어, 벤츄리관의 출구로부터 유입되는 혼합가스가 하부 공간(C)에서 1차적으로 상호 재혼합된 후에, 격판의 내주면에 의한 구멍을 통해서 공간(D)로 유입되어, 상부덮개에 중심부분에 부딪히면서 방사상으로 유동되어 2차적으로 재혼합된다.According to the present invention as described above, an annular diaphragm is provided inside the outer cylinder located between the salt hole and the venturi tube, and the closed space by the outer cylinder and the upper and lower cover is divided into upper and lower portions through the diaphragm. The structure is divided into two spaces C and D which are partially communicated with each other, and the mixed gas flowing from the outlet of the venturi tube is primarily remixed with each other in the lower space C, It flows into the space D through the hole, radially flows while hitting the central portion of the upper cover, and is secondly remixed.
따라서, 공간(D)의 압력이 전체에 걸쳐서 균일화되고, 외통의 염공을 통해서 외부로 분출되는 혼합가스의 유출량이 균일하게 되어, 혼합가스의 연소가 안정적으로 유지되면서, 연료의 연소율이 증대되고, 불완전연소로 인한 유해가스의 발생이 억제되므로, 본 발명에 따른 가스연소장치를 이용하게 되면, 연소기능이 향상되고, 연료비용이 절감되며, 대기오염이 억제되는 효과를 기대할 수 있게 된다.Therefore, the pressure of the space D is made uniform throughout, the flow rate of the mixed gas ejected to the outside through the salt hole of the outer cylinder is made uniform, and the combustion rate of the fuel is increased while the combustion of the mixed gas is kept stable. Since the generation of harmful gases due to incomplete combustion is suppressed, the use of the gas combustion apparatus according to the present invention can improve the combustion function, reduce the fuel cost, and can suppress the air pollution.
