Description
−第一のものは耐火ブロックのガラス相中へのH2Oの拡散のためである;そして
−第二のものは耐火レンガ上の雰囲気に存在する水酸化ナトリウムの凝縮のためであり、それは高い酸化の程度を伴ない、実際、酸素燃料燃焼炉の場合の六倍高い酸化度である。
Claims (10)
- 流路形状の溶融タンクを含むガラス溶融炉であって、バッチ材料が上流端で導入され、溶融されたガラスが下流端で回収され、前記炉がバーナーによって加熱され、燃焼エネルギーの少なくとも65%が酸素燃料燃焼によって生成され、バーナーが炉の長さに沿って壁上に分布され、燃焼排ガス放出の大部分が、バッチ材料が導入される開口の近くの上流端の近くに局在化され、燃焼排ガスの残りが下流部分の近くで除去され、かくして周囲の雰囲気に対して動的封止を維持し、バーナーが、炉への出力の少なくとも40%、好ましくは少なくとも50%が溶融領域に送出されるように分布される、溶融炉。
- 溶融領域に送出される出力が炉の全出力の80%を超えない、好ましくはその70%を超えない、請求項1に記載の溶融炉。
- バーナーがバッチ材料充填領域及び燃焼排ガス放出地点からある距離に位置される、請求項1又は2に記載の溶融炉。
- 第一バーナー、即ちガラスが進む方向に沿った第一のバーナーが、溶融されていないバッチ材料が存在する領域の上に炉の長さに沿って設けられる、請求項1〜3のいずれかに記載の溶融炉。
- 最大出力が溶融領域と精製領域の間の境界で炉の長さに沿って送出される、請求項1〜4のいずれかに記載の溶融炉。
- 第一バーナーを運転する出力と最後のバーナーを運転する出力が、他のバーナーを運転する出力より低い、請求項1〜5のいずれかに記載の溶融炉。
- バーナーが溶融物の上にある距離で炉の囲い内に広がり、その距離は0.25m以上、好ましくは0.40m以上である、請求項1〜6のいずれかに記載の溶融炉。
- バーナーが溶融物の上にある距離で炉の囲い内に広がり、その距離は1.0m以下、好ましくは0.8m以下である、請求項1〜7のいずれかに記載の溶融炉。
- 充填領域において、この領域に限られた量のエネルギーを供給するための電極を含む、請求項1〜8のいずれかに記載の溶融炉。
- 電極によって供給されるエネルギーの量が、炉内で使用されるエネルギーの全量の10%を超えない、好ましくはその最大5%である、請求項9に記載の溶融炉。
