気を通過させて拡散させる拡散用空気穴とを有し
た第１の保炎器をノズルの近傍に配設し、 ドラフトチユーブの中心軸とほぼ平行な多数の
貫通穴を有した多孔体よりなる第２の保炎器をノ
ズルの下流側における前記第１の保炎器から所定
間隔を有した位置に配設した ことを特徴とする燃料噴霧式バーナ。[Scope of Claim for Utility Model Registration] In a fuel spray burner equipped with a fuel spray nozzle in the draft tube, a fuel passage hole that is located opposite to the nozzle and allows the sprayed fuel to pass through, and a region around the fuel passage hole. A first flame stabilizer having a diffusion air hole through which air passes and diffuses is disposed near the nozzle, and is made of a porous body having a large number of through holes approximately parallel to the central axis of the draft tube. A fuel spray burner characterized in that a second flame stabilizer is disposed downstream of a nozzle at a position with a predetermined distance from the first flame stabilizer.
