スワラ−旋回方向、−）は旋回角度で例えば４５°、（
β）は内外方向角度で例えば３０°である。For example, when burning carbon-rich fuels such as LPG, other natural gas, CM, C4 gas, etc., in order to improve the mixing with air and achieve complete combustion, the gas jet nozzle is set at an ejection angle. A method such as crossing the outflow direction (turning the gas and air in opposite directions) is often used. FIG. 1 shows an example of the structure around the conventional gas nozzle. In the figure (35
) is the gas nozzle, (17) is the burner body, arrow (X) is the swirler - rotation direction, -) is the rotation angle, for example 45°, (
β) is an angle in the mediolateral direction, and is, for example, 30°.
またガスノズルまわりのカーボン付着防止対策として、
ガス噴出口の周囲にノ（−ナタイル（耐火物）（６）を
打込み、この部分の温度を高くする方法をとっていた。In addition, as a measure to prevent carbon adhesion around the gas nozzle,
The method used was to inject refractories (6) around the gas outlet to raise the temperature of this area.

However, there is also a lack of air near the gas nozzle, and the gas that is drawn into the burner tile surface will not be fully combusted. Problems such as carbon buildup often occurred. That is, FIG. 2 shows an example of the overall structure of a conventional gas nozzle combustion chamber, the flow of gas and air, and the state of carbon deposition. In addition, FIG. 3 is a front view of the fire port.

同時にこれ等混合促進構造をとり入れたガスバーナでは
燃焼時の釜鳴り発生も見られる現象であつた。At the same time, gas burners incorporating such a mixing promotion structure have also been observed to generate kettle noise during combustion.
本発明は上記に鑑み為されたものでろって、バーナタイ

円に３次空気噴出口を設けてこれ等の諸問題を解決する
ことにしたものである。以下例示の第４〜６図について
本発明の詳細な説明する。The present invention has been made in view of the above, and solves these problems by adopting a flame-holding plate structure instead of burner tiles and providing tertiary air jets concentrically around the outer periphery of the gas nozzle. This is what I did. The present invention will be described in detail below with reference to illustrative FIGS. 4 to 6.

The figure shows the overall structure of the fire pit, the flow of gas and air, and the state of flame-holding combustion. FIG. 6 is a front view of the fire pit. In these FIGS. 4 to 6, the same reference numerals as in FIGS. 1 to 3 indicate the same parts, and the others (38) indicate holes.
即ちガス噴出口（１）の部分はパイプ状にして一定の長

るようにしておる。That is, the gas outlet (1) is shaped like a pipe and has a certain length. This pipe-shaped portion (38) will be referred to as a nozzle pipe hereinafter. A flame-holding plate (also) is provided at the tip of this nozzle pipe (38) so as to fill the space between the nozzle pipes, and the flame-holding plate (36) at the nozzle pipe opening is set at an appropriate angle than the outer diameter of the nozzle pipe (58). Large perforation (37) (
The tertiary air (14) is ejected from the gap between the outer periphery of the nozzle pipe (35) and the perforation (37) of the flame stabilizing plate (36).
この構造によると、ガスノズルの周囲から空気（３次空
気）が供給される為、保炎板前面に巻込んだガス燃料は
この空気により燃焼を開始するので従来方式のこの部分
の空気不足によるカーボン発生が解消されることになる
。同時にこの保炎板前面での保炎燃焼により着火位置は
安定し、燃焼の安全性が保証される。According to this structure, since air (tertiary air) is supplied from around the gas nozzle, the gas fuel caught in front of the flame stabilizing plate starts combustion due to this air. The outbreak will be eliminated. At the same time, flame-holding combustion in front of the flame-holding plate stabilizes the ignition position and guarantees combustion safety.
またこの３次空気の供給により燃焼が早期に開始され、
全体としても燃焼の完結が早められて、ガス噴出口に旋
回角を設ける等混合性を良くする様な従来方式の細工は
不要となる。従って混合性を良くする為の極端な渦流燃
焼は回避され、また前述の通り着火位置も安定するので
釜鳴り現象も解消されることになる。In addition, combustion starts early due to the supply of tertiary air,
As a whole, the completion of combustion is accelerated, and there is no need for conventional techniques to improve mixing properties, such as providing a swirl angle at the gas jet port. Therefore, extreme vortex combustion for improving mixing properties is avoided, and as mentioned above, the ignition position is stabilized, so the kettle noise phenomenon is eliminated.
更に燃料遮断弁が閉じた後で低速で流出するガスは３次
空気の噴出により燃焼は吹消され、同時に早期冷却され
るのでカーボン付着も防止される。Furthermore, combustion of the gas that flows out at a low speed after the fuel cutoff valve closes is blown out by the jet of tertiary air, and at the same time, it is early cooled, so that carbon deposition is also prevented.
（燃料遮断後も炉内掃気の為、しばらくは送風機は運転
されるので５次空気は噴出する。）(Even after the fuel is cut off, the blower will continue to operate for a while to scavenge air inside the furnace, so 5th air will still be blown out.)
