Abstract

設備コストを過度に上昇させることなく、回転炉床式還元炉の排ガス処理設備におけるダスト付着による閉塞や設備の腐食劣化などのトラブルを防止しつつ、排ガスの顕熱を回転炉床式還元炉のバーナ燃焼用空気の予熱に有効に利用しうる排ガス処理装置及び方法を提供する。その装置は、回転炉床式還元炉から排出される排ガスと空気とを熱交換させるための輻射式熱交換器２を備える。この輻射式熱交換器２は、排ガスが流通するための空間を囲む金属製の内筒２２と、この内筒の径方向外側に配置され、この内筒との間に前記排ガスと熱交換すべき空気が流通するための流路を形成する外筒２１と、内筒２２の内面を覆うようにその内側に施工される高熱伝導性耐火物２３とを有する。
