PROBLEM TO BE SOLVED: To provide a vapor injection system capable of injecting vapor continuously for longer hours while restricting cavitation.SOLUTION: A vapor injection is started from a state in which pressure in a space storing vapor within liquid storing segments is higher than saturation vapor pressure of any one of two or more kinds of liquids by a vapor injection system comprising: liquid storing segments 2A, 2B separately storing two or more kinds of liquids non-soluble to each other; injection ports 8 for injecting vapor generated through vaporization of two or more kinds of liquids within the liquid storing segments; and injection control segments 7A, 7B and 7C for controlling vapor injection from the injection ports. Or, a vapor injection may also be started from a state in which pressure in a space storing vapor within fluid storing segments is higher than saturation vapor pressure of liquid by another vapor injection system comprising: fluid storing segments for storing one type of liquid and at least one type of inert gas of which composition is different from the liquid; similar injection ports; and an injection control part. 【課題】キャビテーションを抑制しつつ、長時間にわたって連続的に蒸気を噴射することができる、蒸気噴射システムを提供する。【解決手段】互いに非可溶性である２種類以上の液体を分離して収容する液体収容部２Ａ、２Ｂと、２種類以上の液体が液体収容部の内部で気化することで発生した蒸気を噴射する噴射口８と、噴射口からの蒸気の噴射を制御する噴射制御部７Ａ、７Ｂ、７Ｃとを備えた蒸気噴射システムによって、液体収容部内で蒸気を収容する空間内の圧力が２種類以上の液体のいずれにおける飽和蒸気圧よりも高い状態から蒸気の噴射を開始する。あるいは、１種類の液体と、液体とは組成が異なる少なくとも１種類の不活性ガスを収容する流体収容部と、同様の噴射口及び噴射制御部を備えた蒸気噴射システムによって、流体収容部内で蒸気を収容する空間内の圧力が液体の飽和蒸気圧よりも高い状態から蒸気の噴射を開始してもよい。【選択図】図１
