Description
‐第1のカテゴリーは、「再燃焼」技術を利用して、NOxの生成を低減するものである。この方法では、炉の燃焼室の中に空気のない領域が作り出される。この技術には、蓄熱室の積層レンガの温度が上昇し、場合によっては、特に気密性と耐食性に関して、蓄熱室とその積層レンガが特殊な設計になる、という欠点がある。
‐第2のカテゴリーは、火炎に作用し、火炎中のNOxの生成を低減する、又は、阻止するものである。このためには、例えば、過剰な燃焼用空気を低減するとよい。また、火炎の長さを維持し、火炎前部の体積を大きくして、火炎の中心における平均温度を下げ、温度のピークを制限することも可能である。このような解決法は、例えば、特許文献1と特許文献2に記載されている。この解決法は、ガラスの溶融のための燃焼方法から成り、この方法では、燃料の供給と酸化剤の供給の両方が、NOxの放出量を低減するよう、燃料と酸化剤との接触時間を拡張するか、又は、燃料と酸化剤との接触の体積を増大させるようになされる。
‐液体燃料、
‐高圧気体燃料、
‐低圧気体燃料
を導く同軸の3つの通路をこの順番で軸から遠ざかるようにして備える少なくとも1つのインジェクタを有するバーナーを使用して、NOxを低減することを提案している。しかし、このインジェクタでは、さまざまな燃料の相対的な割合を変化させたい場合に、低NOx放出を維持するためには、複雑な調節が必要である。
‐上記で定義した1つ又は複数のインジェクタを備えるバーナーと;
‐このようなバーナーを少なくとも1つ備える炉、特にエンド・ポート式炉又はサイド・ポート式炉、を提供することである。
Claims (5)

液体燃料の推力と単一の気体燃料の推力との両方によって火炎を生成させ、全パワーに対する、液体燃料に基づくパワーの比率を、20〜80%とし、気体燃料の比推力を最大で2.05N/MWに制限し、かつ液体燃料の比推力を1N/MWを超えないようにして、生成する煙に含まれるNOxの含有量が、サイド・ポート式炉に関しては800mg/Nm3を超えず、エンド・ポート式炉に関しては600mg/Nm3を超えないようにすることを特徴とする方法。 - 液体燃料の前記入口ダクトが、液体燃料を、インジェクタから放出する前に中空旋回ジェットの形態にするための、斜め方向の通路が設けられた要素を備え、前記通路各々の母線は、液体燃料の入口方向と2〜30度の角度をなしていることを特徴とする、請求項1に記載の方法。
- 前記インジェクタをガス100%で作動させるため、液体燃料の前記入口ダクトと、液体燃料の噴霧用の前記流体の入口ダクトとが、前記インジェクタから取外し可能であることを特徴とする、請求項1又は2に記載の方法。
- 1つ又は複数の前記インジェクタを備えるバーナーを用いて行う、請求項1〜3のいずれか一項に記載の方法。
