Abstract
【解決手段】 本発明の一つの態様では、銅イオン触媒/燃焼助剤の存在下で微粉炭を燃料として燃焼させる。これらの系において、2−アミノエタノールのような第一アミノアルコール、トリエタノールアミンのような第三アミノアルコール及びホウ酸又はその水溶性塩形態のブレンドを使用することにより腐食を抑制する。
Description
アミノアルコール成分(1種以上)及びホウ酸又は塩 1〜10wt%
グルコン酸ナトリウム 1〜15wt%
銅(Cu++として)* 0〜20wt%
水 残部。
2−アミノエタノールとトリエタノールアミン及びホウ酸
又は塩のアミノアルコールブレンド 1〜10wt%
グルコン酸ナトリウム 1〜15wt%
銅(Cu++として)* 1〜20wt%
*銅化合物は水溶液中のCu++イオンの必要量が得られるように調整される。
実施例1
腐食速度の対比のためのボトル試験法
実験手順
銅系燃焼増強剤(CBCE)=19%硫酸銅五水和物(4.84%Cu2+、この銅レベルは試験した以下のすべての原液においても同じである。)/1.6%アルキルポリグルコシド界面活性剤(Triton BG−10)。
実施例1に記載した手順を比較処理剤及び本発明の処理剤について再び実施した。結果を表2に示す。
