【発明の詳細な説明】
本発明はスリツリ状の炎口を有するガスバーナにおいて
、火炎長が短く、しかも火炎安定性の良いものを提供す
ることを目的とする。DETAILED DESCRIPTION OF THE INVENTION An object of the present invention is to provide a gas burner having a slit-like flame port with a short flame length and good flame stability.
従来におけるガスバーナはスリット状炎口を多数有し、
第6図に示すように炎口1はスリットの短辺側が対向す
るように配置して群となし、このように形成したバーナ
本体2,3を平行に2連並べて配置していた。Conventional gas burners have many slit-shaped flame ports,
As shown in FIG. 6, the flame ports 1 were arranged in groups so that the short sides of the slits faced each other, and two burner bodies 2 and 3 thus formed were arranged in parallel.
このように形成したバーナの特徴は2連のバーナ間で対
置する隣の炎口群の炎口との間に還流域が生じ、安定な
火炎が得られることである。A feature of the burner formed in this manner is that a reflux area is created between the two sets of burners and the flame ports of the adjacent flame port group, which are opposed to each other, so that a stable flame can be obtained.
しかしこのようなバ〜すにおいてはバーナの軸線方向に
配置された各炎口群の隣合う火炎が重なり、各炎口群全
体として−っの火炎4に形成されて燃焼する。However, in such a burner, the adjacent flames of each burner port group arranged in the axial direction of the burner overlap, and each burner port group as a whole is formed into a single flame 4 and combusted.
2連に配置されたバーナ本体2,3間に生ずる凹部6へ
供給される燃焼用空気の一部は炎口群の両端部6,7か
ら流入しているが、流入が充分でなかった。さらに両端
部が閉じている場合はもっと空気の流入が悪くなって火
炎は長くなり、隣の列の炎口群の火炎と干渉し、火炎が
重なって好ましくなかった。A portion of the combustion air supplied to the recess 6 formed between the burner bodies 2 and 3 arranged in two series was flowing in from both ends 6 and 7 of the burner port group, but the inflow was not sufficient. Furthermore, if both ends were closed, the inflow of air would be worse, the flame would be longer, and the flames would interfere with the flames of the adjacent row of flame ports, causing the flames to overlap, which was undesirable.
そこで四部5への空気の供給を多くするため連結部8を
長くして隣接する炎口1の火炎が重なり合うのを妨げ、
かつ連結部8より空気を供給すると伝う方策がとられて
いた。しかしこの場合炎口1の間を離すことによりバー
ナ全体が長くなる欠点を有していた。Therefore, in order to increase the supply of air to the four parts 5, the connecting part 8 is lengthened to prevent the flames of adjacent flame ports 1 from overlapping.
In addition, a measure was taken to supply air from the connecting portion 8. However, in this case, the disadvantage is that by separating the burner ports 1, the entire burner becomes longer.
本発明は上述のような2連以上の多連構造のバーナが有
していた従来の欠点を除去し、火炎が短く、しかも火炎
安定性の良いバーナを提供するものである。The present invention eliminates the drawbacks of the conventional burner having a multiple structure of two or more burners as described above, and provides a burner with a short flame and good flame stability.
以下本発明の一実施例について詳述する。バーナば軸線
方向に複数の炎口群を配置した2連のバーナ本体9,1
0からなり、このバーナ本体9゜10はそれぞれバーナ

が連結部13を介して結合さノ1ている。各バーナ本体
9.10の間には凹部14が形成されており、四部14
0両端は開放している。An embodiment of the present invention will be described in detail below. Two burner bodies 9, 1 each having a plurality of burner ports arranged in the axial direction of the burner.
The burner main bodies 9 and 10 are arranged in a staggered manner with flame ports 11 facing outside the burner and flame ports 12 facing inside the burner, and adjacent flame ports 11 and 12.
are connected via a connecting portion 13. A recess 14 is formed between each burner body 9.10, and four parts 14
0 Both ends are open.
ノズル16から供給された燃料ガスは一次空気16を吸
引し、混合管17を経て混合ガスとなり、各炎口部に供
給されて火炎18を形成する。この火炎は通常−火炎1
9と二火炎2oで構成されているが、この時−次空気が
多いと二火炎20が小さくなり、−次空気が多いと二火
炎20だけとなる。The fuel gas supplied from the nozzle 16 sucks the primary air 16, passes through the mixing pipe 17, becomes a mixed gas, and is supplied to each flame port to form a flame 18. This flame is normal - flame 1
9 and two flames 2o, but at this time, if there is a lot of secondary air, the two flames 20 will be small, and if there is a lot of negative air, there will be only two flames 20.
二火炎20は二次空気で燃える拡散炎であり、二次空気
の供給が良いとよく燃えて火炎長は短くなる。The secondary flame 20 is a diffusion flame that burns with secondary air, and when the secondary air is supplied well, it burns well and the flame length becomes short.
上述のような構成では連結部13が・く−ナの軸方向に
短くても炎口11.12が千鳥足状に配列されているこ
とから隣接する炎口の間隔が実質的に離れていると同じ
効果を持ち、炎口からの炎同志も互いに独立分離した状
態で燃焼することから隣接する炎口間からの空気21の
流入がよくなり、火炎長の短い安定した燃焼状態かえら
れる。In the above-mentioned configuration, even if the connecting portion 13 is short in the axial direction of the burner, since the flame ports 11 and 12 are arranged in a staggered pattern, the intervals between adjacent flame ports are substantially far apart. It has the same effect, and since the flames from the flame ports burn independently and separated from each other, air 21 can flow in from adjacent flame ports better, and a stable combustion state with a short flame length can be achieved.
さらに千鳥足状に複数の炎口11,12を配列したバー
ナ本体9,10を2連配置していることから2連のバー
ナ本体9,10間の凹部14には対応する炎口同志の間
に還流域22が生じ、火炎の安定性をさらにたかめる効
果を有している。Furthermore, since two burner bodies 9, 10 each having a plurality of burner ports 11, 12 arranged in a staggered pattern are arranged, the recess 14 between the two burner bodies 9, 10 has a gap between the corresponding burner ports. A reflux region 22 is generated, which has the effect of further increasing the stability of the flame.
またこの還流域22には炎口間の連結部21の上部から
の空気の流入があり、さらに一部は炎口群の両端からの
流入もあり、火炎18の内側にも2次空気が供給されて
良好な燃焼が行なわれ、火炎が短く、かつ安定性の良い
ものとなる。In addition, air flows into this return region 22 from the upper part of the connecting part 21 between the flame ports, and some air also flows in from both ends of the flame port group, and secondary air is also supplied to the inside of the flame 18. This results in good combustion, a short flame, and good stability.
また第4図に示すように、2連のバ〜す本体9゜1oの
両端が互いに閉じていても良く、この場合は両端からの
空気流入は少くなるが還流域が生じ易くなり、壕だ一方
炎口間から多くの空気が流入することから火炎長の短い
安定した燃焼を得ることができる。Furthermore, as shown in Figure 4, both ends of the two bar bodies 9゜1o may be closed. In this case, the air inflow from both ends is reduced, but a return region is likely to occur, and a trench is formed. On the other hand, since a large amount of air flows in between the flame ports, stable combustion with a short flame length can be achieved.
また第1図に示すように千鳥足状に配列された炎口群を
有する2連のバーナ本体9,10は対向するそれぞれの
炎口11,12が同じ方向を向くように、すなわち対向
する炎口間隔がすべての炎口11.12に対して同じ間
隔になるように配列することによってさらに還流域を形
成し易くし、対向する炎口間の距離を一定にできる。Further, as shown in FIG. 1, the two burner bodies 9 and 10 having the burner ports arranged in a staggered manner are arranged so that the opposing burner ports 11 and 12 face the same direction. By arranging all the flame ports 11, 12 so that the spacing is the same, it becomes easier to form a return area and the distance between the opposing flame ports can be made constant.
また炎口11.12に中板23を挿入して逆火防止を行
っても火炎の分離には何らの影響もない。Further, even if the middle plate 23 is inserted into the flame port 11, 12 to prevent backfire, there is no effect on flame separation.
以上のように、本発明は火炎長が短く、かつ火炎安定性
の良いバーナを提供する実用的価値の犬なるものである
。As described above, the present invention has practical value in providing a burner with a short flame length and good flame stability.
