PROBLEM TO BE SOLVED: To provide a power generation system that can have its performance improved by increasing the output.SOLUTION: A power generation system has a heat source medium heat exchange part, a medium turbine, a condenser, and a regeneration heater. The heat source medium heat exchange part exchanges heat between a low-boiling-point medium which has a lower boiling point than water and a heat source medium. The low-boiling-point medium having exchanged heat at the heat source medium heat exchange part flows as a working medium into the medium turbine. The condenser condenses the low-boiling-point medium discharged from the medium turbine. The regeneration heater exchanges heat between the low-boiling point medium condensed by the condenser and the low-boiling-point medium extracted from the medium turbine. Here, the regeneration heater is a direct contact type in which heat is exchanged such that the low-boiling-point medium condensed by the condenser and the low-boiling-point medium extracted from the medium turbine come into direct contact with each other, and the low-boiling-point medium having exchanged heat flows in the heat source medium heat exchange part. 【課題】出力を増加し、性能を向上することができる、発電システムを提供する。【解決手段】実施形態の発電システムは、熱源媒体熱交換部と、媒体タービンと、凝縮器と、再生ヒータとを有する。熱源媒体熱交換部では、沸点が水よりも低い低沸点媒体と熱源媒体との間の熱交換が行なわれる。媒体タービンでは、熱源媒体熱交換部において熱交換が行われた低沸点媒体が、作動媒体として流入する。凝縮器は、媒体タービンから排気された低沸点媒体を凝縮する。再生ヒータでは、凝縮器において凝縮された低沸点媒体と媒体タービンから抽気された低沸点媒体との間の熱交換が行なわれる。ここで、再生ヒータは、凝縮器において凝縮された低沸点媒体と媒体タービンから抽気された低沸点媒体との両者が直接的に接触することによって熱交換が行われる直接接触式であり、当該熱交換が行われた低沸点媒体が、熱源媒体熱交換部に流入する。【選択図】図１
