Abstract
Description
図3は、ボイラのバーナ構造を示す水平方向の断面図である。この従来構造において、バーナ10は、ボイラの火炉1内へ燃料及び燃焼用空気を投入する装置である。なお、図中の符号2は火炉壁面、3は火炉壁面2の火炉側に形成された水冷壁であり、図示のバーナ10は、ボイラのコーナー部に配置された構成例である。
バーナ10は、火炉1内へ燃焼用空気を投入する空気流路11を形成している風箱12と、火炉1内へ燃料を投入する燃料パイプ20とを備えている。燃料パイプ20の先端部には燃料ノズル21が設けられ、該燃料ノズル21の外周には風箱12内の空気流路11に連通する空気ノズル22が設けられている。燃料ノズル21からは石炭や重油などの燃料と一次空気が噴出され、空気ノズル22からは二次空気(燃焼用空気)が噴出される。
風箱12内に形成された空気流路11は、ボイラをコンパクト化するために受ける配置経路の制約等から、一般的には火炉1の直前で90°以上に大きく曲がった曲がり部13を有する形状となることが多い。このような曲がり部13では、燃焼用空気の流れに剥離や偏流が生じるため、風箱12内の空気流路11にガイドベーン14を設置して剥離や偏流を防止する構造が採用されている。なお、図中の符号15は、燃焼用空気の流量を調整するため、ガイドベーン14の手前(上流)に設けたダンパである。
また、ボイラの燃焼に関する従来技術として、バーナポートや空気投入ポート毎の偏差を改善したり、逆にバイアスを強化するものがある。(たとえば、特許文献1参照)
具体的に説明すると、曲がり部13を通過した空気流は、遠心力等の影響により流路外側の流速を増すので、バーナ出口から火炉1へ投入される燃焼用空気の流速には、たとえば図4(a)に示すような火炉内幅方向(左右方向)の流速差を生じることとなる。すなわち、曲がり部13の外側を流れた燃焼用空気は、図3の紙面上(右)側から火炉1内へ流出するので、図4(a)における火炉内幅方向位置の下(左)側より上(右)側の流速が高くなり、この結果、燃焼用空気量が不足気味となる火炉内幅方向位置の下(左)側ではCOの発生量を増すことになる。
また、ボイラの燃焼改善については、複数あるバーナポートや空気投入ポート毎に偏差を改善する従来技術や、バイアスを強化することで対応する従来技術はあるものの、バーナ単体での流量偏差改善に関する技術は見当たらない。すなわち、バーナ10の単体に着目し、バーナ10内に生じる空気偏流やアンバランスの解消を狙った従来技術はなく、従って、今後のCOやVOCの厳しい規制に対応するためには、バーナ単体でより精度の高い燃焼用空気の空気流制御を実施することが求められる。
また、精度の高い燃焼用空気の空気流量制御が可能なバーナ構造は、バーナ単体の空気流量制御を有効利用した逆運用により、高スラッギング性燃料の使用時には、火炉壁面側の空気流量を増すことで燃焼性の高い火炉に対するスラッギング防止が可能になる。さらに、腐食性燃料の使用時には、火炉壁面側の空気流量を増すことで腐食原因の硫化水素濃度が低減するので、火炉壁面の腐食防止に有効である。

図1に示すボイラのバーナ構造において、石炭や重油炊きのボイラに取り付けられるバーナ10Aは、火炉1内へ燃料及び燃焼用空気を投入して燃焼させる装置である。図示のバーナ10Aは、一例としてボイラコーナ部に配設された構成例を示している。なお、図中の符号2は火炉壁面、3は火炉壁面2の火炉側に形成された水冷壁である。
風箱12内に形成された空気流路11は、火炉1の直前で90°以上に大きく曲がった曲がり部13を有する形状となっている。このような曲がり部13では、燃焼用空気の流れに剥離や偏流が生じるため、風箱12内の空気流路11には剥離防止用のガイドベーン14が設置されている。図示の例では、空気流路11の曲がり部13がガイドベーン14によって内外(左右)の空気流路11A,11Bに2分割されている。
なお、図中の符号15は、燃焼用空気の流量を調整するダンパであり、ガイドベーン14の手前(上流)に設置することで空気流路11に供給される空気流量を一括制御することができる。
この偏流制御ダンパ16は、燃焼用空気流量を制御するダンパ15の下流に設けられている。また、この偏流制御ダンパ16は、ガイドベーン14で2分割された空気流路11A,11Bの両方に設置し、両方のダンパ開度制御を実施するようにしてもよいが、2分割された空気流路11A,11B毎の流路抵抗比が可変となればよいので、いずれか一方のみに設けたダンパの開度制御をすればよい。従って、図示のバーナ10Aでは、ガイドベーン14で仕切られた二つの空気流路11A,11Bのうち、略U字状となる曲がり部13において流路外周(大径)側となる空気流路11Bで、かつ、曲がり部13の入口部近傍となる位置に、偏流制御用ダンパ16が設置されている。
なお、図1及び図2の火炉内幅方向において、壁面との距離は右側が近い壁面寄りとなっている。
すなわち、偏流制御ダンパ16の開度調整により空気流路11Bの流路抵抗が変化するので、偏流制御ダンパ16の開度調整により空気流路11A,11Bの流路抵抗比を適切に設定して、バーナ出口の左右における空気流速(空気流量)のアンバランスを解消または低減するとともに、COの発生量も低減することができる。
また、上述した実施形態では、ガイドベーン14が空気流路11を2分割した構成例を示しているが、3分割またはそれ以上に分割されている場合には、たとえば最も内側の1箇所を除く分割空気流路毎に各々独立した開度制御が可能な偏流制御ダンパ16を設け、各分割空気流路毎の流路抵抗比を調整するようにすればよい。
センサ17A,17Bで検出した流量等の検出値は、偏流制御ダンパ16の開度制御を行う制御部18に入力される。なお、図示の構成例では、制御部18が偏流制御ダンパ16の駆動モータ16aとともにダンパ15の駆動モータ15aも制御するように構成されているが、これに限定されるものではない。
このように、アンバランスを解消するために設けた偏流制御ダンパ16を逆運用することにより、火炉壁面2側へ積極的に燃焼用空気を流すことができるので、有効なスラッギング防止対策となる。
また、精度の高い燃焼用空気の空気流量制御が可能なバーナ構造は、バーナ10A単体の空気流量制御を有効利用した逆運用により、火炉壁面2側の空気流量を増すことで燃焼性の高い火炉に対するスラッギングを防止し、腐食性燃料使用時の腐食を防止することができる。
なお、本発明は上述した実施形態に限定されるものではなく、たとえばバーナ配置がコーナー配置や壁面配置の場合に適用することにより、左右の偏差解消や逆運用による腐食防止が可能になるなど、本発明の要旨を逸脱しない範囲内において適宜変更することができる。
