Description
−バッチは炉の長手中心軸(X−X)に平行な充填方向で炉に導入され、バッチを実質的に連続的かつ均一に規定された充填幅を亘って分配し、溶融物表面にバッチの層を形成すること;および
−オキシ燃料バーナは前記溶融物上に配置され、そのバーナはバッチの溶融前面を前記層中に存在させるように前記バッチ層に向ける
を含む原料のバッチ溶融方法を提示する。
−前記バーナは横長(horizontally elongate)断面を有する平坦な火炎フレーム(12)を発生する;
−前記火炎の長手断面および前記炉の前記軸(X−X)に対して直角な水平方向を含む面は前記溶融物(4)の表面から測定される前記バッチ層の厚さの1/3と1/2の間の高さ(h)でバッチ溶融前面に交差し、かつ前記炉の前記軸(X−X)に対して直角な線に沿う前記溶融物(4)の表面に交差する;および
−前記火炎(12)は前記バッチ(3)から溶融前面に実質的に放射的に熱の移動を発生する、
ようになされる、前記バーナのパラメータを調節する工程をさらに含む。
ここで、ΔHはバッチの溶融平均エンタルピーを示し、ρは層2中のバッチの密度を示し、Vは供給速度を示す。それゆえ、口105での望ましい産出によってバーナ10の加熱力を調節できる。酸素および燃料の消費は、したがって産出に応じたバッチの量を溶融するために丁度十分値に低減してもよい。例示すると、ガラス製造でのバッチ供給速度12kg/hにとって、バーナ10を経由する20Sm3/hの酸素に対し10Sm3/hの天然ガスを注入できる。
−方法は特に安定な溶融条件を提供する;
−大容量炉で遂行されてもよい;
−バーナは取り付けが簡単でかつ炉のクラウンに僅かな備品のみを要求する;
−炉装備およびメンテナンス費用が低減する;
−燃料および酸素の消費量が減少する;
−炉から抽出される溶融材料は非常に均一である:
−溶融前面に対して向かう火炎は層から炉の外部および燃料を通してもたらすバッチダストを炉の下流端に伝達することを妨げるスクリーンを構成する;
−方法は柔軟であり、かつ異なるバッチが同じ炉で続けて溶融されるときに容易にできる。バーナパラメータは、溶融前面の直線形状を復元するようにそれぞれのバッチに対してのみ調節される。任意に、それらのパラメータは充填方向に沿う溶融前面を書くバッチに対して適切な位置に配置するように調節してもよい;
−方法は容易に自動化することができる;
の多くの有益さを有することを示す。
