〔産業上の利用分野〕
本発明は、給湯偵、暖房機などに用いる先混合式がスバ
ーナに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a pre-mixing type svarna used in hot water heaters, heaters, etc.
家庭用のガス給湯筬、暖房機などには設Ｒ性の向上、建
物との調和、デッドスペースの有効利用などからコンパ
クト化が強く望まれている。There is a strong desire for household gas hot water heaters, space heaters, etc. to be more compact in order to improve ease of installation, harmonize with buildings, and make effective use of dead space.
そして従来上記ｉ′：ｉ３には、空燃比の制御性、火炎
の安定性に対して有利なブンゼン式ガスバーナが用いら
れ、高負荷燃焼を可能とするために二次空気の拡散を促
進する各種の形態が提案されてきた。Conventionally, Bunsen type gas burners, which are advantageous in terms of controllability of air-fuel ratio and flame stability, have been used for i':i3, and various types of gas burners have been used to promote the diffusion of secondary air to enable high-load combustion. forms have been proposed.
又、二次空気の拡散が不要となる全予混合式ガスバーナ
の利用による高負荷燃焼方式の検討も試みられている。Also, attempts are being made to consider high-load combustion methods using fully premixed gas burners, which eliminate the need for secondary air diffusion.
しかしながらブンゼン式がスバーナの場合、火炎長に対
し二次空気の拡散が支配的となり大幅な燃焼空間の小形
化が難かしく製品を十分にコンパクト化することが困難
であった。However, in the case of a Bunsen type svarna, the diffusion of secondary air becomes dominant over the flame length, making it difficult to significantly downsize the combustion space and making the product sufficiently compact.
一方、全予混合式ガスバーナの場合には二次空気０拡散
力ゞ不要であり、短火炎化力ｆ可ｑ＝となりフンゼン式
がスバーナの場合より燃焼空間を小形化することができ
る。しかしながら、火炎の吹消えを防止するため、空気
比（理論空気量に対する燃焼用空気量の比）を大きくす
ることができない。On the other hand, in the case of a fully premixed gas burner, there is no need for the secondary air to have a zero diffusion force, and the short flame forming force f can be obtained, so that the combustion space can be made smaller than in the case of a Hunsen burner. However, in order to prevent the flame from blowing out, the air ratio (the ratio of the combustion air amount to the theoretical air amount) cannot be increased.
このために燃焼ガスが高温となり、燃焼ガス中の一酸化
炭素（以下ＣＯと称す）、窒素酸化物（以下ＮＯｘ
と称す）などの環境汚染物質が高濃度となる欠点がある
。又、燃焼速度の早いガスでは条件により逆火する場合
があり、炎口部の寸法を消炎距離以下とする必要がある
ためバーナ部における圧力損失が増大し燃焼用空気を送
るファンが大形になる欠点がある。さらに燃料ガスと燃
焼用空気を予め混合する装置が必要となりコストが上昇
するなど種々の問題点があった。For this reason, the combustion gas becomes high temperature, and carbon monoxide (hereinafter referred to as CO) and nitrogen oxides (hereinafter referred to as NOx) are produced in the combustion gas.
It has the disadvantage of high concentrations of environmental pollutants such as In addition, gases with a fast combustion rate may cause backfire depending on the conditions, and the size of the flame opening must be smaller than the extinguishing distance, which increases pressure loss in the burner and requires a large fan to send combustion air. There is a drawback. Furthermore, there are various problems such as the need for a device to mix fuel gas and combustion air in advance, which increases cost.
本発明の目的は上記のような欠点がなく高負荷燃焼が可
能な先混合式がスバーナを提供することにある。An object of the present invention is to provide a pre-mixing type sburner which does not have the above-mentioned drawbacks and is capable of high-load combustion.

分割配置されている。A gas passage 12 and an air passage 15 are provided in the burner plate 1 by a large number of holes extending vertically through the burner plate 1 at an angle. On the upper surface 9 of the burner plate 1, the gas passage 12
The gas outlet 11 of the burner plate 1 and the air outlet 14 of the ventilation passage 15 are uniformly arranged over the entire surface so that the air outlet 14 surrounds the gas outlet 11.
On the lower surface 8, a gas inlet 10 in the gas passage 12 and an air inlet 13 in the air passage 15 are arranged to be divided left and right.

到る。The present invention has the above configuration, and its operation will be explained. First, the fuel gas and air are introduced into the gas introduction hole 4 and the air introduction hole 5, respectively, and the air flows through a large number of gas inlets 10 opening on the lower surface 8 of the burner plate 1 in the gas distribution chamber 6 and the air distribution chamber 7. It flows uniformly into the inlet 13. Next, it passes through the inclined gas passage 12 and air passage 15 to reach the upper surface 9.

ので逆火することなく、また、空気比が多少変動しても
吹き消えることはない。On the upper surface 9, the air outlet 14 surrounds the gas outlet 11, so that the fuel gas and air are instantly mixed. As mentioned above, since fuel gas and air are supplied independently, there is no flashback, and even if the air ratio fluctuates slightly, the fuel will not blow out.

場合にも適用可能である。In addition, the combustion temperature, which has a large effect on the generation of Co, NOx, etc., can be easily adjusted by changing the amount of air, and there is no need to ensure a flame extinguishing distance to prevent backfire, allowing the fan to be smaller. . Furthermore, the upper surface 9 of the burner plate 1
Since the fuel gas and air are instantly mixed, the combustion space can be made smaller because the combustion is equivalent to that of a fully premixed gas burner.Furthermore, the burner plate 1 itself has the function of a mixer. Therefore, a mixer is not required. Note that the pre-mixing type gas burner according to the present invention is not limited to gas, but can also be applied to the case where liquid fuel such as kerosene is vaporized and burned.
