- 空気から分離した酸素と、燃料の石炭を燃焼して蒸気需要設備に供給する蒸気を発生させたボイラから排出された排ガスから分岐した排ガスの一部とを混合し、石炭を燃焼させる支燃ガスとして該ボイラに供給するように構成した酸素燃焼ボイラにおいて、
前記ボイラから排出された排ガスを流下させるように配設された排ガス系統のうち、該ボイラの排ガス用出口と該ボイラへ排ガスの一部を循環させるために該排ガス系統から排ガスの一部を分岐させる分岐点との間の領域に、排ガスから熱を回収する熱回収器と、該熱回収器の下流側に排ガスの煤塵を除去する集塵装置と、該集塵装置の下流側に排ガスの硫黄酸化物を除去する脱硫装置と、該脱硫装置の下流側に排ガスの水分を除去する冷却除湿装置を順次設置し、
前記排ガス系統の該分岐点から分岐した排ガスの一部を該ボイラに循環して供給する排ガス循環系統を配設し、
前記排ガス循環系統に排ガスを加熱する再熱器を設置し、
前記熱回収器と再熱器との間に循環水を循環させる循環水系統を配設し、この循環水系統を流れる循環水の流量を調節することによって熱回収器で排ガスから回収する熱量を制御することを特徴とする酸素燃焼ボイラ。 - 請求項1に記載の酸素燃焼ボイラにおいて、
前記熱回収器と前記再熱器との間に、排ガスとの伝熱を行う媒体として水を循環させる
循環水系統を配設したことを特徴とする酸素燃焼ボイラ。
