본 고안은 가열로에서 사용되는 가스버너에 관한 것이며, 더 상세히는 연소기로 유입되는 유량이 비교적 적은 유량이 연료공급이 될때, 연료가스의 유로가 버너노즐이 큰쪽에서 작은쪽으로 바뀌며, 이때 공기비를 맞추기 위하여 동시에 접변으로 비선회류 공기를 차단하고, 선회류공기와 작은버너노즐에서 분사되는 가스연료를 연소시켜 화염조절을 하므로서 연소부하범위를 확장시킬 수 있도록 한 화염조절용 가스버너에 관한 것이다.The present invention relates to a gas burner used in a heating furnace, and more particularly, when the flow rate of the fuel flow into the combustor is relatively small, the flow rate of the fuel gas changes from the larger burner nozzle to the smaller one. The present invention relates to a flame control gas burner which is capable of extending the combustion load range by simultaneously controlling non-orbiting air by tangential contact and burning the gas fuel injected from the swirling air and the small burner nozzle to control the flame.
이러한 형태로 되어있는 종래의 가스버너에 비교적 적은 유량의 연료공급이 될때 버너노즐의 경이 변화하지 않으므로 분사되는 가스연료의 속도가 줄어들어 원하는 화염길이를 얻을 수 없으며, 또한 연소가 불안정하여 가열로내의 분위기온도를 적절히 조절할 수 없는 문제점이 있었다.Since the burner nozzle diameter does not change when the fuel gas is supplied to the conventional gas burner having a relatively low flow rate, the speed of the injected gas fuel is reduced, and thus the desired flame length is not obtained. There was a problem that the temperature can not be properly adjusted.
본고안은 이러한 종래의 문제점을 해결하기 위하여 안출한 것으로서, 특히 화염조절이 적절하게 이루어질 수 있도록 구조를 개선한 화염조절용 가스버너를 제공하는데 그 목적이있다.The purpose of the present invention is to provide a flame control gas burner having an improved structure so that flame control can be appropriately made.
본 고안의 목적을 달성하기 위한 실시장치로는 연료의 유량이 적어질때 버너노즐의 작은쪽으로 연료를 들어가게 하므로서 연료의 속도를 크게함과 동시에 비선회류를 차단하고 선회류만을 사용하여 공기비를 조절하는 구성으로 가능케 된다.In order to achieve the object of the present invention, when the flow rate of the fuel is reduced, the fuel enters into the small side of the burner nozzle, thereby increasing the speed of the fuel and blocking the non-turn flow and adjusting the air ratio using only the swirl flow. It is possible.
이하, 도면에서 본 고안에 의한 실시장치를 상세히 설명한다.Hereinafter, the embodiment according to the present invention in the drawings will be described in detail.
본 고안은, 제1도 및 제2도에서 도시한 바와같이 주연료관(1)에서의 연료가 삼방변(4)을 통하여 유입되고, 이 삼방변(4)에서는 그 연료의 양에따라 제3연료지관(3)을 통하여는 소직경노즐(10)로, 제2연료지관(2)을 통해서는 대직경노즐(9)로 각기 연료가 유입되는 구성으로 된다.According to the present invention, as shown in FIGS. 1 and 2, the fuel in the main fuel pipe 1 flows in through the three sides 4, and in the three sides 4 according to the amount of the fuel. Each fuel flows into the small diameter nozzle 10 through the 3 fuel branch pipe 3, and into the large diameter nozzle 9 through the 2nd fuel branch pipe 2, respectively.
상기 소직경노즐(10)로의 연료 유입시에는 연소공기의 접변(5)이 닫히므로 선회익(12)으로의 공기만이 유입되는 구성으로 된다.When the fuel flows into the small-diameter nozzle 10, the contact 5 of the combustion air is closed, so that only air to the swing blade 12 is introduced.
상기 삼방변(4)의 개폐작동시 연료가 버너에의 공급이 차단되는 것을 피하기 위한 제1연료지관(7)을 주연료관(1)으로부터 연설하며, 이로부터 조연버너노즐(11)로의 연료가 공급되어지고, 이에 개폐변(8)을 두어 가스연료공급이 차단될 수 있는 구성으로 된다.The first fuel branch (7) is delivered from the main fuel pipe (1) to avoid the supply of fuel to the burner during the opening and closing operation of the three-way (4), from which the fuel to the supporting burner nozzle (11) Is supplied, and the opening and closing side (8) is provided so that the gas fuel supply can be cut off.
미설명부호 6은 접변(5)을 조절하기위한 핸들, 13은 공기통로, a1,a2는 편의상 부여된 제1,2연소공기, f는 가스연료이다.Reference numeral 6 denotes a handle for adjusting the edge 5, 13 an air passage, a1, a2 are first and second combustion air provided for convenience, and f is a gas fuel.
이와같이 구성된 본 고안에 의한 실시장치의 작용 및 효과를 설명한다.The operation and effects of the embodiment according to the present invention configured as described above will be described.
즉, 본 고안은 제1도 및 제2도에서 도시한 바와같이 가스연료(f)는 주연료관(1)을 따라서 삼방변(4)에 도달케되고, 이 삼방변(4)의 개폐동작으로 가스연료(f)가 본 고안의 버너에 공급되어진다.That is, according to the present invention, as shown in FIGS. 1 and 2, the gas fuel f reaches the three sides 4 along the main fuel pipe 1, and the opening and closing operation of the three sides 4 is performed. Gas fuel f is supplied to the burner of the present invention.
이때 상기 삼방변(4)에 의해 개폐동작시 가스연료(f)가 공급되는 것을 차단시킬 우려가 있으므로, 제1연료지관(7)을 통하여 조연버너노들(11)로 가스연료(f)를 계속 공급케 되는 것이며, 이는 개폐변(8)으로 가스연료(f)공급을 차단시킬 수도 있게된다.At this time, since the gas fuel f may be blocked from being supplied during the opening and closing operation by the three-way valve 4, the gas fuel f is continued to the burner burner nodes 11 through the first fuel branch pipe 7. It is to be supplied, which may cut off the gas fuel (f) supply to the open and close side (8).
한편, 가스연료(f)는 유량이 상대적으로 많아질 경우에는 자동 또는 수동으로 삼방변(4)이 작동되고, 상기 가스연료(f)는 제2연료지관(2)을 통하여 대직경노즐(9)로 가스연료(f)가 분사된다.On the other hand, the gas fuel (f) is a three-way (4) is automatically or manually operated when the flow rate is relatively high, the gas fuel (f) is a large diameter nozzle (9) through the second fuel branch pipe (2) ), Gas fuel f is injected.
그리고, 이때의 연소공기(a1,a2)는 접변(5)을 통하여 공기통로(13)로 유입된 직진류의 제2연소공기(a2)와, 선회익(12)을 거친 선회류의 제1연소공기(a1)와의 혼합 공기로 주어진다.Then, the combustion air (a1, a2) at this time is the first of the swirl flow through the second combustion air (a2) of the linear flow flowing into the air passage (13) through the contact (5), and the rotor blade (12) It is given as mixed air with combustion air a1.
또한, 가스연료(f)의 유량이 상대적으로 적어질때에는 삼방변(4)이 작동되어 상기 가스연료(f)가 제3연료지관(3)으로 유입되고, 소직경노즐(10)로 연료가 분사된다.In addition, when the flow rate of the gaseous fuel (f) is relatively low, the three-way side (4) is operated so that the gaseous fuel (f) flows into the third fuel branch pipe (3), the fuel flows into the small diameter nozzle (10) Sprayed.
이때는 역시 접변(5)은 닫히게되고, 선회익(12)으로 선회류공기만의 제1연소공기(a1)로 제공된다.At this time, the edge 5 is also closed, and is provided to the first combustion air a1 of the swirling air only by the swirling blades 12.
이와같이 된 본 고안은 종래 가스버너와는 달리, 가스버너에 유입되는 공급유량의 많고 적음에 따라 독립적인 가스노즐(9,10,11)로의 연료공급이 선택적으로 이뤄질 수 있고, 그 연소공기도 함께 가변할 수 있는 가스버너를 제공함에 의해, 이러 버너에 있어서의 연소부하범위를 양호히 확장케되는 유익한 효과가 있는 실용적인 고안이다.Unlike the conventional gas burner, the present invention has a large and small supply flow rate flowing into the gas burner, so that fuel supply to the independent gas nozzles 9, 10 and 11 can be selectively performed, and the combustion air is By providing a gas burner that can be varied, it is a practical design with the beneficial effect of extending the combustion load range in such a burner well.
