本考案は保炎性能が良くて燃焼異常音のない多炎孔板型
ガスバーナに関する。[Detailed Description of the Invention] The present invention relates to a multi-flame hole plate type gas burner with good flame holding performance and no abnormal combustion noise.
１０〜３Ｑｍｍφ程度の丸棒の端焼きにはロータノーハ
ース炉がよく用いられており、その加熱用バーナとして
は燃結金属等の多孔質板を用いたしみ出し燃焼バーナ、
多炎孔板型バーナ、単炎孔型バーナ等各種形式のバーナ
が用いられている。A rotor no-hearth furnace is often used for end-burning round bars of about 10 to 3 Qmmφ, and its heating burner includes a seepage combustion burner using a porous plate made of sintered metal, etc.
Various types of burners are used, such as multi-flame hole plate burners and single-flame hole burners.
この場合多裂孔板型バーナを用いればしみ出し燃焼型バ
ーナに比べて、耐久性、耐逆火性の点で秀れていること
は従来から良く知られている。In this case, it has been well known that if a multi-hole plate burner is used, it is superior in terms of durability and flashback resistance compared to a seepage combustion burner.
しかし多炎孔板型バーナは１０００〜２０００ Ｈｚの
異常音が発生し易すいことと、保炎方法が難かしいとい
う２つの欠点があった。However, the multi-flame hole plate type burner has two drawbacks: it tends to generate abnormal noise of 1000 to 2000 Hz, and it is difficult to maintain the flame.
本考案はこれらの欠点を除いた多炎孔板型バーナを提供
せんとするものである。The present invention aims to provide a multi-flame hole plate burner that eliminates these drawbacks.
本考案を図面に基づいて説明する。The present invention will be explained based on the drawings.
第１図は本考案による多炎孔板型バーナの断面図であり
第２図は第１図バーナの多裂孔板の正面図である。FIG. 1 is a sectional view of a multi-hole plate type burner according to the present invention, and FIG. 2 is a front view of the multi-hole plate of the burner shown in FIG.
混合気接続口１より混合気室２に導入された混合ガスは
混合気室２にて更に混合された後長方形の多裂孔板３よ
り噴出し点火装置（図示せず）により点火燃焼する。The mixed gas introduced into the mixture chamber 2 through the mixture connection port 1 is further mixed in the mixture chamber 2, and then ejected from the rectangular multi-hole plate 3 and ignited and burned by an ignition device (not shown).
この多裂孔板は第２図に示す如く長方形としその厚さは
１２ｍｍ程度、炎孔径は２〜３ｍｍφである。As shown in FIG. 2, this multi-hole plate is rectangular, has a thickness of about 12 mm, and a flame hole diameter of 2 to 3 mm.
多裂孔板３より噴出燃焼したガスは低辺が多裂孔板３と
同形で長さＬであるバーナタイルで囲まれた空間より燃
焼室５へ流出し燃焼する。The gas ejected and burned from the multi-perforated plate 3 flows into the combustion chamber 5 from a space surrounded by burner tiles whose lower sides are the same shape as the multi-perforated plate 3 and has a length L, and is combusted.
この場合、多裂孔板３の短辺Ａ即ちバーナタイルで囲ま
れた空間の底辺Ａとガス流れ方向の長さＬとの比がある
範囲にあるときは保炎性能もよく異常音も発生しないこ
とを本考案者等を発見した。In this case, when the ratio of the short side A of the multi-perforated plate 3, that is, the bottom side A of the space surrounded by the burner tiles, and the length L in the gas flow direction is within a certain range, the flame holding performance is good and no abnormal noise is generated. This is what the inventors discovered.
即ち多炎孔板型バーナの異常音、保炎性能はバーナタイ
ルで囲まれた炎孔先端部の空間の形状寸法に大きく影響
され、第１図のバーナタイル部りの長さが長い程保炎性
能は良好であるが、異常音が発生しやすく、またＬが小
さい程保炎性能は悪くなるが異常音が発生しにくくなる
ことを見出した。In other words, the abnormal noise and flame holding performance of a multi-flame hole plate burner are greatly influenced by the shape and dimensions of the space at the tip of the flame hole surrounded by the burner tiles, and the longer the length of the burner tile in Figure 1, the better the flame holding performance. It has been found that although L is good, abnormal noises are more likely to be generated, and that the smaller L is, the worse the flame holding performance is, but that abnormal noises are less likely to be generated.
その関係を表にすれば次の通りである。The relationship is shown in the table below.
但し ○印は保炎性能良、又は異常音無し×印は保炎性
能不良、又は異常音有り
△印は保炎性能、異常音基々○×の中間
これらの実験結果よりバーナタイル部短辺Ａとガス流れ
方向バーナタイル長さＬとの比が２゜５〜５．５の間に
あるときは保炎性能良好で燃焼異常音のないバーナを得
ることができた。However, ○ indicates good flame holding performance, or no abnormal noise. When the ratio of A to the burner tile length L in the gas flow direction was between 2.5 and 5.5, a burner with good flame holding performance and no abnormal combustion noise could be obtained.
なお請求範囲は長方影身炎孔板バーナに限定したがこれ
はバーナ製作の容易性によるものであり、第２図点線に
示す如く短辺Ａ部が円形又は楕円形であっても本考案の
効果は同じである。Note that although the claimed scope is limited to a rectangular shadow flame hole plate burner, this is due to the ease of manufacturing the burner, and the present invention is applicable even if the short side A is circular or oval as shown by the dotted line in Figure 2. The effect is the same.
