Abstract

　本発明にかかる排ガス処理装置は、ボイラから排出される排ガス１６中の窒素酸化物及び水銀をアンモニア脱硝触媒で除去する排ガス処理装置であって、ボイラの燃焼ガス１１のガス煙道１０ａに設けられたエコノマイザ１５の入口近傍又はエコノマイザ１５をバイパスして高温の燃焼ガス１１を後流側に迂回させるエコノマイザバイパス部１５ａのいずれか一方又は両方に、塩化アンモニウム（ＮＨ4Ｃｌ）を粉体状で供給する塩化アンモニウム供給部１０１を設けてなり、前記塩化アンモニウムを燃焼ガス１１の高温雰囲気温度により昇華させて、塩化水素及びアンモニアを排ガス煙道１０２内に供給してなる。本発明により、排ガス処理設備の省略化ができる。
