本考案は、バーナノズルに形成した複数本の燃
料噴出路を、燃料油供給路と燃料ガス供給路に連
通する混合室に接続したガスアトマイズバーナに
関する。[Detailed description of the invention] [Field of industrial application] The present invention relates to a gas atomizing burner in which a plurality of fuel injection passages formed in a burner nozzle are connected to a mixing chamber communicating with a fuel oil supply passage and a fuel gas supply passage. .
従来、第４図に示すように、燃料油供給路１０

燃焼用空気流１９とガスアトマイズバーナＡから
の燃料噴出流２０を混合して燃焼させるように構
成していた。
Conventionally, as shown in FIG.
b and the fuel gas supply path 11 are connected to each of the plurality of mixing chambers 12, and the linear fuel injection path 21 is connected to each of the mixing chambers 12 over the entire length, thereby forming the burner nozzle 7.
As shown in FIG. 3, the combustion air flow 19 from the outlet 18 and the fuel jet flow 20 from the gas atomizing burner A are mixed and combusted inside the glass melting tank furnace 17 or the like. It was composed.
しかし、燃料噴出路２１が全長にわたつて一直
線状であるために、燃料噴出路２１夫々からの燃
料噴出流２０の流動乱れが少なくて、燃料噴出流
２０と燃焼用空気流１８との混合が不十分とな

Ｆの衝突により炉壁１７ａが早期に損傷し、一層
の改良の余地があつた。
However, since the fuel jet passages 21 are straight over the entire length, there is little flow turbulence in the fuel jet flows 20 from each of the fuel jet passages 21, and the mixture of the fuel jet flows 20 and the combustion air flow 18 is reduced. If the combustion chamber load was increased, the flame F would extend, and the furnace wall 17a would be damaged early due to the collision of the flame F, leaving room for further improvement.
本考案の目的は、燃料噴出路からの燃料噴出流
における流動乱れを十分に大きくして、燃料噴出
流と燃焼用空気流との混合を良くし、燃焼室負荷
を十分に増大できるようにすると共に、そのため
の構成を制作簡単なものにする点にある。 The purpose of this invention is to sufficiently increase the flow turbulence in the fuel jet flow from the fuel jet passage, improve the mixing of the fuel jet flow with the combustion air flow, and sufficiently increase the combustion chamber load. In addition, the purpose of the present invention is to make the configuration for this purpose easy to produce.
本考案の特徴構成は、燃料油と燃料ガスの混合
室に接続してバーナノズルに形成した複数本の燃
料噴出路夫々において、噴出口側の第１ストレー

用効果は次の通りである。
A characteristic configuration of the present invention is that, in each of the plurality of fuel injection passages formed in the burner nozzle connected to the mixing chamber for fuel oil and fuel gas, a first straight passage portion on the injection port side and a second straight passage portion on the mixing chamber side. The straight flow path portions are connected in a curved manner, and the effects are as follows.
つまり、噴出口側の第１ストレート流路部分を

回した状態となつて乱れの大きなものとなる。
In other words, if the first straight flow path portion on the jet side is connected to the second straight flow path portion on the mixing chamber side while being bent at a small angle, preferably about 1 to 5 degrees, the second straight flow path portion The fuel flow from the first straight flow passage collides with the inner wall surface of the first straight flow path portion and becomes a swirling flow along the inner wall surface, so that each fuel jet flow from the fuel jet passages is in a state of swirling around its center. This will cause a lot of disturbance.

燃焼室負荷をかなり増大しても、燃焼室内の炎の
延びを十分に抑えて、炎による炉壁損傷を防止で
きる。 Therefore, the mixing of the fuel jet flow from the gas atomizing burner and the combustion air flow supplied to the combustion chamber is significantly improved due to the swirling of the fuel jet flow,
Even if the combustion chamber load increases considerably, the extension of the flame within the combustion chamber can be sufficiently suppressed and damage to the furnace wall caused by the flame can be prevented.

工できる。 Furthermore, since the fuel injection passage is formed in the first and second straight flow passages, the burner nozzle can be easily fabricated by drilling holes from the front side of the burner nozzle and drilling holes from the back side of the burner nozzle. .
その結果、燃焼室負荷を従来型式よりも十分に
大きくできる燃焼性能において一段と優れたガス
