燃焼バーナとして、簡単な構造で燃焼性を向上させることが可能な部分予混合形式の燃焼バーナが知られている（特許文献１参照）。   As a combustion burner, a partial premixing type combustion burner capable of improving combustibility with a simple structure is known (see Patent Document 1).

図１０は特許文献１に記載された燃焼バーナを燃焼室に取り付けた状態を示す図、図１１は図１０の燃焼室の燃焼バーナの水平断面図、図１２（ａ）は図１１のＦ−Ｆ矢視図、（ｂ）は図１１のＥ−Ｅ矢視図、（ｃ）は燃焼室の内部からバーナタイルを視たＤ−Ｄ矢視図である。   10 is a view showing a state in which the combustion burner described in Patent Document 1 is attached to the combustion chamber, FIG. 11 is a horizontal sectional view of the combustion burner in the combustion chamber of FIG. 10, and FIG. F arrow figure, (b) is the EE arrow figure of FIG. 11, (c) is DD arrow figure which looked at the burner tile from the inside of a combustion chamber.

燃焼バーナ１は燃焼室２に取り付けられ、廃棄物処理炉で発生した可燃性ガスは燃焼空気と混合されて燃焼室内で燃焼する。   The combustion burner 1 is attached to the combustion chamber 2, and the combustible gas generated in the waste treatment furnace is mixed with the combustion air and burned in the combustion chamber.

可燃性ガスは、燃焼室２に可燃性ガス流路である可燃性ガスダクト２０を経由して導入され、燃焼空気は燃焼空気ダクト２１を経由して風箱２２へ導入される。   The combustible gas is introduced into the combustion chamber 2 via the combustible gas duct 20 that is a combustible gas flow path, and the combustion air is introduced into the wind box 22 via the combustion air duct 21.

導入された可燃性ガスと燃焼空気は、風箱２２端部のバーナタイル２３に形成された混合ガス噴出口２４と可燃性ガスダクト２０の出口との間に形成されたガス混合室２５で部分予混合した上で複数の混合ガス噴出口２４から燃焼室１内に噴出し火炎を形成する。   The introduced combustible gas and combustion air are partially preliminarily stored in the gas mixing chamber 25 formed between the mixed gas outlet 24 formed in the burner tile 23 at the end of the wind box 22 and the outlet of the combustible gas duct 20. After mixing, a flame is formed by jetting into the combustion chamber 1 from the plurality of mixed gas outlets 24.

特開２００６−２６６６１９号公報JP 2006-266619 A

前記特許文献１に記載された燃焼バーナでは、可燃性ガス流路である可燃性ガスダクトの周囲のみからの燃焼空気による混合となるため均一に混合することができない。特に大型バーナの場合にはガス流路の周囲が大きくなるため、さらに均一に混合しにくくなる。また、可燃性ガスが高温ガスの場合、ガス分岐部が耐熱上、メタリック化できない。   The combustion burner described in Patent Document 1 cannot be uniformly mixed because it is mixed by combustion air only from around the combustible gas duct that is the combustible gas flow path. In particular, in the case of a large burner, the circumference of the gas flow path becomes large, and it becomes difficult to mix evenly. Further, when the combustible gas is a high-temperature gas, the gas branch portion cannot be made metallic due to heat resistance.

そこで、本発明は、可燃性ガスと燃焼空気を均一に混合することができるメタリックポートを有する燃焼バーナを提供するものである。   Therefore, the present invention provides a combustion burner having a metallic port that can uniformly mix a combustible gas and combustion air.

本発明は、廃棄物をガス化して発生する可燃性ガスを各吐出ポートごとに燃焼空気で挟み込んで混合して燃焼させる燃焼バーナにおいて、可燃性ガスを導入する可燃性ガス流路の外周を取り囲んで外部から燃焼空気が取り込まれる流路が形成され、該流路の途中は整流板で仕切られ、整流板の下流側には上部空気室、下部空気室、左側空気室および右側空気室が上下左右に仕切られて独立して配置され、前記整流板には所定量の燃焼空気を分配する開口を設け、左側空気室および右側空気室には可燃性ガスの吐出ポートの外側の側面にスリット状の燃焼空気吐出ノズルが設けられ、可燃性ガス流路を複数の流路に分岐するための分岐ポストが可燃性ガス流路出口付近に設けられ、分岐ポスト内は上部空気室および下部空気室と通じるとともに、可燃性ガス流路の吐出ポートの内側の側面に燃焼空気を分岐して吐出する二つのスリット状の燃焼空気吐出ノズルが設けられていることを特徴とする。 The present invention surrounds the outer periphery of a combustible gas passage for introducing a combustible gas in a combustion burner in which combustible gas generated by gasifying waste is sandwiched between combustion air for each discharge port and mixed and combusted. A flow path through which combustion air is taken in from outside is formed, and the middle of the flow path is partitioned by a rectifying plate, and an upper air chamber, a lower air chamber, a left air chamber, and a right air chamber are vertically moved downstream of the rectifying plate. The right and left air chambers are provided with openings for distributing a predetermined amount of combustion air, and the left and right air chambers are slit-like on the outer side of the discharge port for combustible gas. The combustion air discharge nozzle is provided, a branch post for branching the combustible gas flow path into a plurality of flow paths is provided in the vicinity of the combustible gas flow path outlet, and the inside of the branch post includes an upper air chamber and a lower air chamber. As well as Wherein the two slit-shaped combustion air discharge nozzle for discharging branches combustion air to the inside of the side surface of the discharge port of the combustible gas flow path is provided.

前記構成において、円形断面の可燃性ガス流路の外周を取り囲んで外部から燃焼空気が取り込まれる上部空気室、下部空気室、左側空気室および右側空気室が配置された二重管構造とし、分岐ポストを円形断面とすることができる。また、分岐ポストを可燃性ガス流路と直交する方向に間隔をおいて複数配置することができる。   In the above configuration, a double-pipe structure in which an upper air chamber, a lower air chamber, a left air chamber, and a right air chamber are arranged so as to surround the outer periphery of a combustible gas flow path having a circular cross section and into which combustion air is taken in from the outside. The post can have a circular cross section. A plurality of branch posts can be arranged at intervals in a direction orthogonal to the combustible gas flow path.

本発明は、各吐出ポートごとに可燃性ガスが空気で挟み込まれるため、確実な混合が可能となる。   In the present invention, since the flammable gas is sandwiched between each discharge port, reliable mixing is possible.

本発明は、分岐部は燃焼空気により冷却されるため、メタリックで形成できる。   In the present invention, the branch portion is cooled by the combustion air, and thus can be formed of metallic.

本発明は、燃焼量が大きなバーナとなってもポート部の寸法を変えずに分岐部の数を増加させることで同じ燃焼性が得られる。   In the present invention, even if the burner has a large combustion amount, the same combustibility can be obtained by increasing the number of branch portions without changing the size of the port portion.

本発明の実施例について図面を参照しながら説明する。   Embodiments of the present invention will be described with reference to the drawings.

図１〜図４において、燃焼バーナ１は燃焼室２に取り付けられ、廃棄物処理炉で発生した可燃性ガスは燃焼空気と混合されて燃焼室内で燃焼する。   1 to 4, a combustion burner 1 is attached to a combustion chamber 2 and combustible gas generated in a waste treatment furnace is mixed with combustion air and burned in the combustion chamber.

廃棄物処理炉で発生した可燃性ガスが導入されて可燃性ガス流路３となる断面が矩形の可燃性ガスポートが中央に配置される。可燃性ガス流路３の外側を取り囲んで風箱２２が形成され燃焼空気ダクト４から燃焼空気を供給する空気流路が形成され、本流路の下流側には風箱２２が整流板９で仕切られており、この整流板９には、燃焼空気を通す開口１０が間隔おいて設けられ、当該整流板９を通過した空気は上部空気室５、下部空気室６、左側空気室７および右側空気室８が独立して配置されている各室に流入する。整流板９の開口１０の断面積に応じた所定量の燃焼空気を上下左右の各空気室内に独立して流すことが可能となっている。   A combustible gas port having a rectangular cross section, which becomes a combustible gas flow path 3 when the combustible gas generated in the waste treatment furnace is introduced, is disposed in the center. A wind box 22 is formed so as to surround the outside of the combustible gas flow path 3 and an air flow path for supplying combustion air from the combustion air duct 4 is formed. The rectifying plate 9 is provided with openings 10 through which combustion air is passed at intervals, and the air that has passed through the rectifying plate 9 passes through the upper air chamber 5, the lower air chamber 6, the left air chamber 7, and the right air. The chamber 8 flows into each chamber that is arranged independently. A predetermined amount of combustion air corresponding to the cross-sectional area of the opening 10 of the rectifying plate 9 can be independently flowed into the upper, lower, left, and right air chambers.

燃焼バーナ１の端部には中間部のバーナタイル１２と周囲部のバーナタイル１３の間に混合ガス噴出口１４が形成される。中間部のバーナタイル１２の上流側には、上部空気室５および下部空気室６の燃焼空気通路１１に連通する屋根形の分岐ポスト１５が１個又は複数個間隔をおいて配置される。分岐ポスト１５と中間部の山形のバーナタイル１２とにより形成される間隙で二つの燃焼空気吐出ノズル１６が形成される。上部空気室５および下部空気室６に導入された燃焼空気は燃焼空気通路１１から分岐ポスト１５に入り込み、燃焼空気吐出ノズル１６から分岐して吐出する。   A gas mixture outlet 14 is formed at the end of the combustion burner 1 between the intermediate burner tile 12 and the peripheral burner tile 13. One or a plurality of roof-shaped branch posts 15 communicating with the combustion air passages 11 of the upper air chamber 5 and the lower air chamber 6 are arranged on the upstream side of the intermediate burner tile 12 at intervals. Two combustion air discharge nozzles 16 are formed by a gap formed by the branch post 15 and the chevron burner tile 12 in the middle. The combustion air introduced into the upper air chamber 5 and the lower air chamber 6 enters the branch post 15 from the combustion air passage 11, branches off from the combustion air discharge nozzle 16 and is discharged.

また、左側空気室７および右側空気室８の燃焼空気通路１１の出口を絞って周囲部のバーナタイルとの間の燃焼空気吐出ノズル１７が形成され、左側空気室７および右側空気室８に導入された燃焼空気が燃焼空気吐出ノズル１７から吐出する。   Further, the outlet of the combustion air passage 11 of the left air chamber 7 and the right air chamber 8 is narrowed to form a combustion air discharge nozzle 17 between the surrounding burner tiles and introduced into the left air chamber 7 and the right air chamber 8. The combustion air thus discharged is discharged from the combustion air discharge nozzle 17.

分岐ポスト１５の燃焼空気吐出ノズル１６と周囲部の燃焼空気吐出ノズル１７を設けることにより、可燃性ガス流路３の端部には可燃性ガスを分流して吐出する可燃性ガス吐出ノズル１８が形成されることになる。こうして可燃性ガス吐出ノズル１８から分岐して吐出した可燃性ガスがそれぞれ燃焼空気吐出ノズル１６，１７から吐出した燃焼空気に挟まれて混合される。   By providing the combustion air discharge nozzle 16 of the branch post 15 and the surrounding combustion air discharge nozzle 17, a combustible gas discharge nozzle 18 that divides and discharges the combustible gas at the end of the combustible gas flow path 3. Will be formed. In this way, the combustible gas branched and discharged from the combustible gas discharge nozzle 18 is sandwiched and mixed by the combustion air discharged from the combustion air discharge nozzles 16 and 17, respectively.

本実施例の燃焼バーナの動作について説明する。   The operation of the combustion burner of this embodiment will be described.

燃焼空気ダクト４から導入された燃焼空気は、風箱２２に入った後整流板９の開口１０で分流されて上下左右の各空気室５〜８に導入される。上部空気室５および下部空気室６に導入された燃焼空気は分岐ポスト１５に入り込んで燃焼空気吐出ノズル１６から吐出し、左側空気室７および右側空気室８に導入された燃焼空気は燃焼空気吐出ノズル１７から吐出する。一方、燃焼空気は可燃性ガス流路３の可燃性ガス吐出ノズル１８から吐出するので、可燃性ガスは燃焼空気吐出ノズル１６，１７から吐出する燃焼空気に挟まれるので、可燃性ガスと燃焼空気とが効率よく混合され、混合ガスは混合ガス噴出口１４から燃焼室内に吹き込まれる。   The combustion air introduced from the combustion air duct 4 enters the wind box 22 and then is divided by the opening 10 of the rectifying plate 9 and introduced into the upper, lower, left and right air chambers 5 to 8. The combustion air introduced into the upper air chamber 5 and the lower air chamber 6 enters the branch post 15 and is discharged from the combustion air discharge nozzle 16. The combustion air introduced into the left air chamber 7 and the right air chamber 8 is discharged as combustion air. It discharges from the nozzle 17. On the other hand, since the combustion air is discharged from the combustible gas discharge nozzle 18 of the combustible gas flow path 3, the combustible gas is sandwiched between the combustion air discharged from the combustion air discharge nozzles 16, 17. Are mixed efficiently, and the mixed gas is blown into the combustion chamber from the mixed gas outlet 14.

可燃性ガス流路の周囲は燃焼空気が通過する風箱２２や上下左右の空気室で囲まれているため常に冷却されており、この結果、高温の可燃性ガスが可燃性ガス流路を通過してもポートに特別の耐火構造を必要とせず、燃焼バーナ全体をメタリックで形成できる。また、燃焼バーナのサイズに応じて、混合ガス噴出口の個数を容易に増加させることができるため、燃焼性を変化させずにスケールアップが可能である。  The flammable gas flow path is always cooled because it is surrounded by a wind box 22 through which combustion air passes and the upper, lower, left, and right air chambers. As a result, high-temperature flammable gas passes through the flammable gas flow path. Even if the port does not require a special fireproof structure, the entire combustion burner can be made of metallic material. In addition, since the number of gas mixture outlets can be easily increased according to the size of the combustion burner, it is possible to scale up without changing the combustibility.

A wind box 22 for supplying combustion air from the combustion air duct 4 is arranged, and the wind box 22 is partitioned downstream by a baffle plate, and the subsequent flow paths are the upper air chamber 5, the lower air chamber 6, and the left air chamber 7. The right air chamber 8 is partitioned.

この整流板９には、燃焼空気を通す開口１０が間隔おいて設けられ、空気室５〜８と可燃性ガス流路３との間で風箱から上、下、左、右の空気室に至る燃焼空気通路１１が形成される。整流板９を設置することで燃焼空気を上下左右の各空気室内に開口１０の断面積に応じた流量を流すことが可能となる。   The rectifying plate 9 is provided with openings 10 through which combustion air is passed at intervals, between the air chambers 5 to 8 and the combustible gas flow path 3, to the upper, lower, left and right air chambers from the wind box. A combustion air passage 11 is formed. By installing the rectifying plate 9, it is possible to flow the combustion air at a flow rate corresponding to the cross-sectional area of the opening 10 in the upper, lower, left, and right air chambers.

燃焼バーナ１の端部の外周には、バーナタイル１３が形成され、左側空気室７および右側空気室８の燃焼空気通路１１の出口を絞ってバーナタイル１３との間に燃焼空気吐出ノズル１７が形成される。左側空気室７および右側空気室８に導入された燃焼空気が燃焼空気吐出ノズル１７から吐出する。   A burner tile 13 is formed on the outer periphery of the end of the combustion burner 1, and a combustion air discharge nozzle 17 is formed between the burner tile 13 by narrowing the outlet of the combustion air passage 11 of the left air chamber 7 and the right air chamber 8. It is formed. The combustion air introduced into the left air chamber 7 and the right air chamber 8 is discharged from the combustion air discharge nozzle 17.

可燃性ガス流路３の可燃性ガス出側の端部の中央には、上部空気室５および下部空気室６の燃焼空気通路１１に連通する断面円形の分岐ポスト１５が配置されている。分岐ポスト１５には燃焼空気吐出ノズル１６が形成されている。燃焼空気吐出ノズル１６は上下に２段且つ左右斜め前方向に向けて一対設けられる。上部空気室５および下部空気室６に導入された燃焼空気は燃焼空気通路１１から分岐ポスト１５に入り込み、燃焼空気吐出ノズル１６から分岐して吐出する。   A branch post 15 having a circular cross section communicating with the combustion air passage 11 of the upper air chamber 5 and the lower air chamber 6 is disposed at the center of the end of the combustible gas passage 3 on the outlet side of the combustible gas. A combustion air discharge nozzle 16 is formed on the branch post 15. A pair of combustion air discharge nozzles 16 are provided in two stages in the vertical direction and in a diagonally forward direction on the left and right. The combustion air introduced into the upper air chamber 5 and the lower air chamber 6 enters the branch post 15 from the combustion air passage 11, branches off from the combustion air discharge nozzle 16 and is discharged.

断面円形の分岐ポスト１５と左右に燃焼空気吐出ノズル１７を設けることにより、可燃性ガス流路３の端部には可燃性ガスを分流して吐出する可燃性ガス吐出ノズル１８が形成されることになる。こうして可燃性ガス吐出ノズル１８から分岐して吐出した可燃性ガスがそれぞれ燃焼空気吐出ノズル１６，１７から吐出した燃焼空気に挟まれて混合される。   By providing the branch post 15 having a circular cross section and the combustion air discharge nozzles 17 on the left and right sides, the combustible gas discharge nozzle 18 for dividing and discharging the combustible gas at the end of the combustible gas flow path 3 is formed. become. In this way, the combustible gas branched and discharged from the combustible gas discharge nozzle 18 is sandwiched and mixed by the combustion air discharged from the combustion air discharge nozzles 16 and 17, respectively.

本実施例の燃焼バーナの動作について説明する。   The operation of the combustion burner of this embodiment will be described.

燃焼空気ダクト４から導入された燃焼空気は、風箱２２に入った後整流板９の開口１０で分流されて上下左右の各空気室内に導入される。上部空気室５および下部空気室６に導入された燃焼空気は分岐ポスト１５に入り込んで燃焼空気吐出ノズル１６から吐出し、左側空気室７および右側空気室８に導入された燃焼空気は燃焼空気吐出ノズル１７から吐出する。一方、燃焼空気は可燃性ガス流路３の可燃性ガス吐出ノズル１８から吐出するので、可燃性ガスは燃焼空気吐出ノズル１６，１７から吐出する燃焼空気に挟まれ、可燃性ガスと燃焼空気とが効率よく混合され、混合ガスは燃焼室内に吹き込まれる。   The combustion air introduced from the combustion air duct 4 enters the wind box 22 and then is divided by the opening 10 of the rectifying plate 9 and introduced into the upper, lower, left and right air chambers. The combustion air introduced into the upper air chamber 5 and the lower air chamber 6 enters the branch post 15 and is discharged from the combustion air discharge nozzle 16. The combustion air introduced into the left air chamber 7 and the right air chamber 8 is discharged as combustion air. It discharges from the nozzle 17. On the other hand, since the combustion air is discharged from the combustible gas discharge nozzle 18 of the combustible gas passage 3, the combustible gas is sandwiched between the combustion air discharged from the combustion air discharge nozzles 16 and 17, and the combustible gas and the combustion air Are efficiently mixed, and the mixed gas is blown into the combustion chamber.

また、可燃性ガス流路３の周囲は燃焼空気が通過する上下左右の空気室５〜８で囲まれているため常に冷却されており、この結果、高温の可燃性ガスが可燃性ガス流路３を通過してもポートに特別の耐火構造を必要とせず、燃焼バーナ全体をメタリックで形成できる。   Moreover, since the periphery of the combustible gas flow path 3 is surrounded by the upper, lower, left, and right air chambers 5 to 8 through which the combustion air passes, it is always cooled. As a result, the high temperature combustible gas is cooled. Even if 3 passes, the port does not require a special fireproof structure, and the entire combustion burner can be formed of metallic.

図９において、実施例１と同一部材には同一符号を付してその説明は省略する。   In FIG. 9, the same members as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

可燃性ガス吐出ノズル１８から吐出する可燃性ガスが全て燃焼空気吐出ノズル１６あるいは１７から吐出する燃焼空気に挟まれるので、可燃性ガスと燃焼空気とが効率よく混合される。燃焼バーナのサイズに応じて、混合ガス噴出口１４の個数を容易に増加させることができる。そのため、燃焼性を変化させずにスケールアップが可能である。   Since all the combustible gas discharged from the combustible gas discharge nozzle 18 is sandwiched between the combustion air discharged from the combustion air discharge nozzle 16 or 17, the combustible gas and the combustion air are efficiently mixed. Depending on the size of the combustion burner, the number of gas mixture outlets 14 can be easily increased. Therefore, it is possible to scale up without changing the combustibility.
