Claims (1)
- 廃棄物のガス化溶融処理施設の燃焼室で燃焼後の高温の排ガスの熱回収を行い、ボイラで排ガスの冷却を行い、ボイラ本体を出た排ガスを直接バグフィルタに導入するボイラ設備の出口ガス温度の制御方法であって、
ボイラ給水を予熱して排ガスの冷却を行う節炭器をボイラ本体のガス出口側に内蔵し、節炭器の一部又は全部をバイパスするバイパス経路を設け、このバイパス経路へのボイラ給水の通水量を調整することにより、出口ガス温度を目標範囲内に制御するボイラ設備の出口ガス温度の制御方法において、
前記節炭器によって予熱したボイラ給水を補給水として受け入れる、ドラム水レベルを一定に保つ気水ドラムのドラム水レベルが、補給水を要求しないレベルにあるときに、節炭器に給水するボイラ給水量を増加させる場合、気水ドラムからドラム水を強制排水して補給水を受け入れることを特徴とするボイラ設備の出口ガス温度の制御方法。
