And, it is invented to lower the flame temperature of the burner to minimize the generation of nitrogen oxides and carbon monoxide.

일반적인 예혼합 열교환기(10)는 공기와 연료가스를 혼합해 상부덮개(12)에 구비된 밴츄리관을 통해 연소 버너부(20)로 공급되도록 하며, 이 연료가스가 케이싱(11) 내부에서 버너부(20)를 이용해 점화, 연소되면서, 현열 및 잠열 열교환부의 순환유체와 열교환 되는 구성을 갖고 있다.A general premix heat exchanger (10) mixes air and fuel gas so that the fuel gas is supplied to the combustion burner unit (20) through a venturi tube provided in the upper cover (12), and the fuel gas is provided in the casing (11). The burner unit 20 is ignited and burned, and has a configuration in which heat is exchanged with the circulating fluid of the sensible and latent heat exchange unit.

본 발명인 예혼합 연소 버너부(20)는 상부덮개(12)의 하부에서 삽입통로(40)와 염공부(30)가 요철형상을 갖고 나열되게 연속 형성되어, 케이싱(11) 상부에 밀폐되도록 결합된다.Pre-mixed combustion burner unit 20 of the present invention is inserted in the lower portion of the upper cover 12, the insertion passage 40 and the salt hole 30 is formed in a row with a concave-convex shape, the casing 11 is coupled to be sealed on the top do.

상기 염공부(30)는 연료가스가 분사되도록 일정한 간격으로 염공(31)이 형성된 몸체를 갖고, 상부덮개(12)의 하부에서 염공부(30)가 다수개 나열되도록 설치하여 오목한 삽입통로(40)와 볼록한 염공부(30)로 구분되도록 한다.The salt hole 30 has a body in which the salt hole 31 is formed at regular intervals so that the fuel gas is injected, and installed so that a plurality of salt hole 30 is arranged in the lower portion of the upper cover 12 concave insertion passage (40) ) And convex salt portion 30 to be distinguished.

이때, 상기 염공부(30)는 금속재질로 성형되며, 몸체 하부로 절곡 형성되어 염공(31)이 배열된 전면판(32)과, 이 전면판(32) 양측에서 절개된 측판(33) 하부의 끝단을 내측으로 절곡시켜 전면판(32)을 고정하도록 구성된다.At this time, the salt hole 30 is formed of a metal material, bent to the bottom of the body is formed by the front plate 32, the salt hole 31 is arranged, and the side plate 33 cut in both sides of the front plate 32 It is configured to fix the front plate 32 by bending the end of the inward.

또, 염공부(30)의 몸체는 하부로 절곡된 전면판(32)과 측판(33)을 제외한 상부면이 상부덮개(12)에 용접 결합되어진다.In addition, the body of the salt hole 30 is welded to the upper cover 12, the upper surface except the front plate 32 and the side plate 33 is bent to the bottom.

따라서, 상부덮개(12) 하부로 결합되는 버너부(20)는, 다수개의 염공부(30)를 나열 결합시키는 구성만으로, 삽입통로(40)와 염공부(30)가 요철형상을 갖게 하며, 케이싱(11)상부로 결합되어 연료가스를 연소시키도록 한다.Therefore, the burner part 20 coupled to the lower part of the upper cover 12 has only a configuration in which a plurality of salt hole parts 30 are coupled to each other, such that the insertion passage 40 and the salt hole part 30 have an uneven shape. It is coupled to the upper casing 11 to burn fuel gas.

그리고, 케이싱(11)의 몸체에는 좌우 양측이 납작하게 눌려진 압착튜브관(50)이 몸체 상부로 상기 삽입통로(40)와 동일한 개수를 갖고 관통되게 결합된다.In addition, the body of the casing 11 is coupled to the left and right sides of the pressurized tube tube 50 that is pressed flatly to have the same number as the insertion passage 40 through the body.

이 압착튜브관(50)은 케이싱(11)내부에서 버너부(20)와 열교환하는 현열, 잠열 열교환부의 순환유체가 내부로 흐르도록 하며, 몸체 좌우 폭이 삽입통로(40)의 폭보다 작게 성형되어, 상부덮개(12) 결합 시 삽입통로(40)에 위치되면서, 좌우 압착면(51)이 염공부(30)의 측판(33)과 밀착되도록 한다.The pressurized tube tube 50 allows the circulating fluid to exchange heat with the burner part 20 in the casing 11 and the circulating fluid of the latent heat exchange part to flow therein, and the body has a width smaller than the width of the insertion passage 40. When the upper cover 12 is coupled to the insertion path 40, the left and right compression surfaces 51 are brought into close contact with the side plate 33 of the salt hole 30.

즉, 상기 압착튜브관(50)은 염공부(30)의 측판(33)과 넓은 면적으로 밀착되도록 몸체가 눌려진 압착면(51)이 형성되며, 몸체 상하부는 호 형상을 갖는 장공형상으로 성형된 것이다.That is, the pressurized tube tube 50 is formed with a pressing surface 51 is pressed body to be in close contact with the side plate 33 of the salt hole 30, the upper and lower body is formed in a long hole shape having an arc shape will be.

이때, 상기 압착튜브관(50)은 연소가스의 흐름방향으로 장축을 갖고 형성되며, 그 길이가 염공부(30)의 돌출높이보다 길도록 하여 압착면(51)과의 밀착부위를 증대시키면서 과냉각시 압착튜브관(50)에 발생되는 결로가 염공부(30)로 침투되는 것을 방지하게 된다.At this time, the compression tube tube 50 is formed with a long axis in the flow direction of the combustion gas, the length thereof is longer than the height of the protruding height of the salt hole 30 to increase the close contact with the pressing surface 51 and supercooled When the condensation generated in the compression tube tube 50 is prevented from penetrating into the salt hole 30.

또, 염공부(30)의 측판(33) 끝단부에도, 유입방지돌출부(34)를 형성시켜 압착튜브관(50)에서 발생되는 결로의 염공부(30)침투를 이중으로 방지하게 되어 안전성이 향상되도록 한다.In addition, the inflow prevention projections 34 are formed at the end portions of the side plates 33 of the salt holes 30, thereby preventing double penetration of the salt holes 30 from the condensation generated in the crimped tube 50. To improve.

그리고, 케이싱(11)의 상부에서 현열,잠열 열교환부와 소정거리를 두고 압착튜브관(50)을 위치시켜 그 사이로 연소실이 형성되며, 이 연소실의 내벽을 따라 압착튜브관(50)의 압착면(51)이 밀착되도록 결합한다.In addition, a compression chamber tube 50 is positioned at a predetermined distance from the sensible heat and latent heat exchanger in the upper part of the casing 11 to form a combustion chamber therebetween, and the compression surface of the compression tube tube 50 is formed along the inner wall of the combustion chamber. Combine the 51 to be in close contact.

이와 같이 구성된 예혼합 연소 버너부(20)를 냉각하기 위한 연소가스 및 순환유체의 흐름과 작동상태를 설명하면 다음과 같다.The flow and operating state of the combustion gas and the circulating fluid for cooling the premixed combustion burner unit 20 configured as described above are as follows.

열교환기(10)의 케이싱(11) 상부로 순환유체가 흐르는 압착튜브관(50)이 다수개 관통되게 설치된다.A plurality of pressurized tube tubes 50 through which a circulating fluid flows are installed on the casing 11 of the heat exchanger 10.

그리고, 케이싱(11) 상부에서 염공부(30)가 다수개 결합되어 요철형상을 갖는 버너부(20)가 케이싱(11)내부에 삽입되게 상부덮개(12)를 결합시킨다.In addition, a plurality of salt holes 30 are coupled to the upper part of the casing 11, and the burner part 20 having an uneven shape is coupled to the upper cover 12 to be inserted into the casing 11.

이때, 상기 버너부(20)의 삽입통로(40)에 압착튜브관(50)이 위치되도록 결합하며, 이 압착튜브관(50)의 압착면(51)과 염공부(30)의 측판(33)은 밀착되어 결합되도록 한다.At this time, the pressurized tube tube 50 is coupled to the insertion path 40 of the burner unit 20 so that the press surface 51 of the pressurized tube tube 50 and the side plate 33 of the salt hole 30 are formed. ) Are tightly coupled.

따라서, 케이싱(11)과 상부덮개(12)가 결합된 열교환기(10)로 연료가스가 공급되면, 버너부(20)의 염공부(30)에서 연소가 이루어지면서, 이 연소열로 열교환부의 순환유체와 열교환되고, 버너부(20)의 몸체온도는 증가하게 된다.Therefore, when fuel gas is supplied to the heat exchanger 10 to which the casing 11 and the upper cover 12 are coupled, combustion occurs in the salt hole 30 of the burner unit 20, and the heat of the heat exchange unit is circulated by the combustion heat. Heat exchanged with the fluid, the body temperature of the burner unit 20 is increased.

그리고, 버너부(20)는 염공부(30)가 다수개 나열되어 그 사이로 순환유체가 흐르는 압착튜브관(50)이 염공부(30)의 측판(33)에 밀착되게 결합되어 있어, 온도가 증가하는 염공부(30)와 순환유체는 열교환이 이루어지도록 하였다.In addition, the burner part 20 has a plurality of salt holes 30 arranged therein, and the compression tube tube 50 through which the circulating fluid flows is tightly coupled to the side plate 33 of the salt holes 30, and thus the temperature is increased. The increasing salt hole 30 and the circulating fluid were to be heat exchange.

따라서, 순환유체와 열교환 된 염공부(30)의 표면온도는 감소되면서, 고온의 화염온도도 낮추게 되어 염공부(30)의 열변형과 질소산화물 및 일산화탄소의 발생을 억제할 수 있는 것이다.Therefore, while the surface temperature of the salt hole 30 exchanged with the circulating fluid is reduced, the flame temperature of the high temperature is also lowered, thereby suppressing thermal deformation and generation of nitrogen oxide and carbon monoxide in the salt hole 30.

또, 염공부(30)의 높이보다 압착튜브관(50)의 높이가 크게 형성되어 차가운 순환유체와 열교환 시 발생되는 응축수가 염공부(30)로 침투되지 않도록 해 연료가스의 완전연소가 이루지도록 한다.In addition, the height of the pressurized tube tube 50 is formed larger than the height of the salt hole 30 so that the condensed water generated during the heat exchange with the cold circulating fluid does not penetrate into the salt hole 30 so as to achieve complete combustion of the fuel gas. do.

또한, 염공부(30)의 측판(33) 끝단으로 유입방지돌출부(34)가 형성되도록 해, 상기 압착튜브관(50)의 높이와 함께 이중의 응축수 침투방지구조를 갖게되어 안전성을 더욱 향상시킬 수 있다.In addition, the inflow prevention protrusion 34 is formed at the end of the side plate 33 of the salt hole 30, and has a double condensate preventing structure with the height of the compression tube tube 50 to further improve safety.
