Abstract
Description
本発明の一の態様に係る注入装置は、液体が流れる配管に、注入液を注入する注入装置であって、前記配管に接続されて、前記注入液が流れる注入配管と、前記注入配管に設けられた注入用ポンプと、前記注入用ポンプよりも下流側で、前記注入配管中の空気抜き対象部位よりも上流側に接続された押出用配管と、前記押出用配管に押出用の液体を送水する押出用ポンプとを備え、前記押出用ポンプの吐出量は、前記注入用ポンプの吐出量よりも大きいことを特徴とする。
以下、本発明の一実施形態に係る注入装置1について、図面を参照して説明する。
蒸気タービン設備100は、ボイラ61と、蒸気タービン51と、蒸気タービン51に接続される外部機器52と、復水器53と、給水ポンプ33と、注入装置1と、補給装置2と、を有している。
注入装置1における薬液タンク41には、上述のヒドラジンやアンモニア等の薬液が貯留されている。薬液タンク41から供給された薬液は、注入配管3を通って給水配管18におけるボイラ61の上流に注入される。上述のように注入される薬液により給水のpHが調整されるため、給水配管18の腐食を防ぐことができる。
より詳細には、B押出用配管6Bは、洗浄用配管5における補給水用ポンプ32から接続部Cにかけての部分と、押出用配管6における接続部Cから注入配管3にかけての部分と、を含む。
