Abstract
【解決手段】分布管4内に、燃焼筒1の先端の手前の位置に亘って軸方向にのびる流入管9を設け、混合気を径方向の運動成分を殆ど持たない流れに整流して、分布管4内に供給する。分布管4の外周に、流入管9の先端から基端側に所定距離L2離して、分布管4と燃焼筒1との隙間を狭める環状の邪魔板10を設ける。流入管9の先端と燃焼筒1の先端との間の軸方向範囲の流入管寄りの部分(cの領域)及び流入管9の先端と邪魔板10の配置箇所の近傍位置との間の部分(dの領域)では、分布管4に分布孔4aを形成しない。

Description
Claims (4)
- 周面に開設された多数の炎孔を有する燃焼筒と、燃焼筒の基端に装着される流入口を有する基板と、燃焼筒の先端に装着される蓋板と、燃焼筒の内部を基板から蓋板に亘って軸方向にのび、燃焼筒内の空間を内外2室に仕切る分布管とを備え、分布管の内側の内室に流入口から混合気を流入させ、内室に流入した混合気を分布管の外側の外室に分布管に形成した多数の分布孔を介して流入させるようにした筒状バーナにおいて、
内室に、流入口に連なり、燃焼筒の先端寄りの位置に亘って軸方向にのびる流入管を配置し、分布管の外周に、流入管の先端から分布管の基端側に所定距離離れた箇所に位置させて、燃焼筒の内周面との間の隙間を狭める環状の邪魔板を設けると共に、
分布管の単位面積当りの分布孔の開口面積を分布孔密度として、流入管の先端と燃焼筒の先端との間の軸方向範囲の流入管の先端寄りの部分及び流入管の先端と邪魔板の配置箇所近傍との間の部分では、分布孔密度を零または零近傍の微小値にすることを特徴とする筒状バーナ。 - 前記燃焼筒の炎孔開設範囲の軸方向最先端は、前記流入管の先端と燃焼筒の先端との間の軸方向範囲の流入管の先端寄りの部分または流入管の先端と邪魔板の配置箇所近傍との間の部分に位置することを特徴とする請求項1記載の筒状バーナ。
- 前記邪魔板の配置箇所近傍の部分での分布孔密度を、前記燃焼筒の基端と邪魔板の配置箇所近傍との間の部分の分布孔密度より大きくすることを特徴とする請求項1または2記載の筒状バーナ。
- 前記流入管の先端と前記燃焼筒の先端との間の軸方向範囲を、流入管の先端寄りの部分と中間部分と燃焼筒の先端寄りの部分との3部分に区分し、燃焼筒の先端寄りの部分での分布孔密度を零または零近傍の微小値とし、中間部分に分布孔を集中して形成することを特徴とする請求項1〜3の何れか1項に記載の筒状バーナ。
