Description
低圧復水器胴10’の低圧ホットウェル5には、一端側が接続され、他端側が中圧復水器2に接続された連絡管6Cを備えている。低圧ホットウェル5に溜まった凝縮水は連絡管6Cにより中圧復水器2に導かれる。中圧復水器2の器内圧力は、低圧復水器1の器内圧力に比べて高いため、連絡管6Cの出口高さは、低圧ホットウェル5の水面より水頭分である(h4)だけ低く設定している。連絡管6Cの出口には滴下部7Cが設けられており、低圧ホットウェル5より導かれた低温の凝縮水を中圧復水器2の比較的高温の蒸気で加熱するようになっている。滴下部7Cで加熱された凝縮水は中圧復水器2で発生した凝縮水と共に中圧ホットウェル8に集められる。滴下部7Cでの加熱を確実に行うため、滴下部7Cと中圧ホットウェル8の水面の間には適切な高さであるh5を確保している。
