本発明は、燃料ガスをファンからの燃焼用空気で燃焼さ
せる装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for burning fuel gas with combustion air from a fan.
従来、第５図に示すように、バーナ（Ｂ）とファン（Ｆ
）を配管（１７）で接続して、管路（１８）からの燃料
ガスをバーナ（Ｂ）で燃焼させるように構成していた。Conventionally, as shown in Fig. 5, a burner (B) and a fan (F
) were connected by a pipe (17), and the fuel gas from the pipe (18) was combusted by a burner (B).
しかし、バーナ（Ｂ）とファン（Ｆ）が別体構成である
ために、装置全体がかなり大型になる欠点があった。However, since the burner (B) and fan (F) are constructed separately, there is a drawback that the entire device becomes quite large.
本発明の目的は、燃焼装置を極めてコンパクトに形成で
きるようにし、しかも、発熱量を装置サイズの割には大
にしながら、炎口夫々における炎のリフトを防止できる
ようにする点にある。SUMMARY OF THE INVENTION An object of the present invention is to enable a combustion apparatus to be formed extremely compactly, and to increase the calorific value relative to the size of the apparatus while preventing flame lift at each burner port.
本発明の特徴構成は、遠心ファンの羽根の内側に燃料ガ

、かつ、前記炎口に対向配置した導電体に正電極を接続
した３〜８ＫＶの直流電源を設けたことにあり、その作
用効果は次の通りである。The characteristic configuration of the present invention is that a fuel gas supply nozzle is arranged inside the blade of a centrifugal fan, and a large number of flame ports are provided for spouting the air-fuel mixture gas supplied by the blade into the burner body surrounding the outside of the blade. A 3 to 8 KV DC power source is provided in which a negative electrode is connected to the burner body and a positive electrode is connected to a conductor placed opposite to the burner, and its effects are as follows. be.
つまり、ノズルによって羽根の内側に供給される燃料ガ

の炎口に送られ、炎口夫々で炎が形成されるのであり、
遠心ファンとバーナを一体形成した状態とすることによ
って、装置全体を前述の従来技術よりも大巾に小型化で
きるようになった。In other words, the fuel gas supplied to the inside of the blade by the nozzle and the air sucked in by the blade are thoroughly mixed through the blade and sent to the numerous flame ports formed on the outer periphery of the blade. A flame is formed at each outlet,
By integrally forming the centrifugal fan and the burner, the entire device can be made much smaller than the prior art described above.

電気的にバーナ本体側に引寄せられ、燃焼室負荷を大き
くしても炎のリフトが抑制され、良好な燃焼が得られる
。Furthermore, by connecting the negative electrode of the DC power source to the burner body and the positive electrode to the conductor facing the flame nozzle, an electric field is created at the location where the flame is formed. The flame is electrically drawn toward the burner body, suppressing flame lift even when the combustion chamber load is increased, and achieving good combustion.

が燃焼室負荷を炎のリフト無しで増大できる事実を確認
できた。To explain further, by changing the air ratio and combustion chamber load variously, the flame lift region and stable combustion region were investigated for the device of the present invention having a DC power source of 3 to ν and a comparative device without a DC power source. The results shown in FIG. 4 were obtained. In other words, in the device of the present invention, flame lift occurs in the region above the solid line and stable combustion occurs in the region below the solid line, whereas in the comparative device, flame lift occurs in the region above the dotted line, and the flame lift occurs in the region below the solid line. Stable combustion occurred in the lower region, confirming the fact that the device of the present invention can increase the combustion chamber load without flame lift.
その結果、例えば湯沸器などの加熱機器を設置面で有利
なように発熱量を大にしながら小型化するに、極めて有
効な燃焼装置を提供できるようになった。As a result, it has become possible to provide a combustion device that is extremely effective in reducing the size of heating equipment, such as water heaters, while increasing the amount of heat generated to be advantageous in terms of installation.
