一つには、炉壁の断熱および保護のために従来使用される耐火セラミクスの過度の摩耗が生じることである。
また、一つには、液中バーナーにより提供される熱エネルギーを、エネルギーの過度の浪費無く必要とされる高い温度を達成するのに充分有効な形で使用することにむずかしさがあることである。
円筒形の混合用チャンバを各々含み、放出オリフィス、燃料供給ダクトおよび酸化剤供給ダクトがシリンダージャケットに対して燃料および酸化剤の接線方向流動をひき起こす方向でシリンダージャケットのレベルで混合用チャンバ内に開放している、複数のインラインインジェクタと、
冷却液がバーナーの内部を流れることができるようにするダクトシステムと、
を含む、液中バーナーにある。
ガラス化可能材料の導入のゾーンと、
溶融材料の出口のゾーンと、
そして導入のゾーンと出口のゾーンとの間の、溶融材料の流動のゾーンと、
を伴うガラスまたは岩石の溶融炉であり、溶融材料の流動のゾーン内に本発明に係る少なくとも1つの液中バーナーを含み、インジェクタの整列方向が本質的に溶融材料の流動方向に対して直交するような形に前記バーナーが設置されている、溶融炉でもある。
ガラス化可能材料を導入するための炉のゾーン内にガラス化可能材料を導入するステップと、
気体燃料、好ましくは天然ガスおよび気体酸化剤、好ましくは酸素を、1つまたは複数の液中バーナーに供給するステップと、
溶融材料の出口のゾーン内に溶融材料を引き出すステップと、
炉壁および/またはバーナー内に専用に具備されたダクトシステムの中で冷却液、好ましくは水を循環させるステップと、
を含む方法にある。
