本発明は、燃焼表面を形成する通気性のセラミックスを
、その裏面が給気室に臨む状態で設けた表面燃焼ノく−
ナに関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a surface combustion nozzle in which a breathable ceramic forming the combustion surface is provided with its back side facing an air supply chamber.
Regarding Na.
従来、燃料ガスの供給路及び燃焼用酸素含有ガスの供給
路の両方を給気室に接続し、給気室において燃料ガスと
燃焼用酸素含有ガスを混合して、混合ガスをセラミック
スから噴出させて燃焼させるように構成していた。Conventionally, both the fuel gas supply path and the combustion oxygen-containing gas supply path are connected to an air supply chamber, the fuel gas and the combustion oxygen-containing gas are mixed in the air supply chamber, and the mixed gas is ejected from the ceramic. It was designed to be combusted.

途には適用できない欠点があった。 ″
本発明の目的は、燃焼用酸素含有ガスの酸素濃度がいか
に高くても逆火が生じないようにし、しかも、表面燃焼
バーナの加熱特性は良好に維持できるようにする点にあ
る。However, as the mixed B gas passes through ceramics, there is a risk of flashback.If flashback occurs, it will cause heating defects and burn out the burner, so in practice, the oxygen concentration of the oxygen-containing gas for combustion cannot be made very high, resulting in a low flame temperature, which has the drawback that it cannot be applied to applications that require high-temperature radiation, for example, Qθ~00a°C. An object of the present invention is to prevent flashback from occurring no matter how high the oxygen concentration of the oxygen-containing gas for combustion, and to maintain good heating characteristics of the surface combustion burner.
本発明の特徴構成は、噴出ガスをセラミックスの燃焼表
面に沿って流動させるノズルを設け、燃料ガスの供給路
及び燃焼用酸素含有ガスの供給路の一方のみを前記セラ
ミックスの裏面に臨む給気室にかつ他方のみをＩＩＩ記
ノズルに接続したことにあり、その作用効果は次の通り
である。The characteristic configuration of the present invention is that a nozzle is provided for causing the ejected gas to flow along the combustion surface of the ceramic, and only one of the fuel gas supply path and the combustion oxygen-containing gas supply path is provided in an air supply chamber facing the back surface of the ceramic. and only the other side is connected to the nozzle III, and its effects are as follows.
つまり、燃料ガスと燃焼用酸素含有ガスを、その一方を
セラミックスから噴出させると同時に他方をノズルから
燃焼表面に沿うように噴出させて混合しかつ燃焼させる
のである。In other words, one of the fuel gas and the combustion oxygen-containing gas is ejected from the ceramic and the other is ejected from the nozzle along the combustion surface to mix and burn.
したがって、セラミックス及びノズルの内部への逆火を
完全に無くせ、逆火防止面から燃焼用酸素含有ガスの酸
素濃度が制約されることが無くなって、酸素や酸素濃度
が極めて高い酸素富化空気を安全に利用できるよ゛うに
なり、炎温度を極めて高くできるようになった。Therefore, backfire inside the ceramics and nozzle can be completely eliminated, and the oxygen concentration of the oxygen-containing gas for combustion is no longer restricted from the viewpoint of preventing flashback, and oxygen and oxygen-enriched air with an extremely high oxygen concentration can be produced. It is now safe to use and allows extremely high flame temperatures.
また、炎が、燃焼表面全体にわたって均等に形成され、
かつ、安定して燃焼表面に着いた状態で形成されること
を、実験によって確認でき、表面燃焼バーナとして要求
される加熱特性を十分に備えさせることができる。Also, the flame is formed evenly over the entire burning surface,
In addition, it has been confirmed through experiments that it is formed in a stable state on the combustion surface, and it can be provided with sufficient heating characteristics required for a surface combustion burner.
その結果、逆火によるトラブルの無い状態で高温放射伝
熱を広範囲にわたって均等に行えるようになり、従来の
表面燃焼バーナでは適用できなかった高温加熱分野での
利用が可能な表面燃焼バーナを提供できるようになった
。As a result, high-temperature radiant heat can be transferred evenly over a wide range without any trouble caused by backfire, making it possible to provide a surface-combustion burner that can be used in high-temperature heating fields that cannot be applied to conventional surface-combustion burners. It became so.
