To provide a power generation device and a working medium circulation device capable of further utilizing thermal energy of exhaust gas discharged from an engine.SOLUTION: A power generation device 2 comprises an exhaust gas binary power generator 5, a heat recovery unit 7, a medium circulation passage LN3, a bypass section 9 and a control section 8. The exhaust gas binary power generator 5 has: an evaporator 51, an expander 52, a generator 53, a condenser 54 and a pump 55. The evaporator 51 generates vapor of a working medium through heat exchange between the working medium and exhaust gas. The heat recovery unit 7 has a plurality of heat exchanger 71 to 79 respectively heating oil through heat exchange with the working medium. The bypass section 9 has a bypass passage 91 arranged so as to bypass the expander 52 and a bypass valve 92 installed on the bypass passage 91. The control section 8 opens the bypass valve 92 so as to allow the working medium to bypass the expander 52 when a temperature of the working medium measured through a temperature measuring section 21 is lower than a saturation temperature.SELECTED DRAWING: Figure 1

    【課題】エンジンから排出される排ガスの熱エネルギをさらに有効利用することができる発電装置および作動媒体循環装置を提供する。【解決手段】発電装置2は、排ガスバイナリ発電機5、熱回収器7、媒体流通路LN3、バイパス部9、および制御部8を備える。排ガスバイナリ発電機5は、蒸発器51、膨張機52、発電機53、凝縮器54、およびポンプ55を備える。蒸発器51では、排ガスとの熱交換により作動媒体の蒸気が発生する。熱回収器7は、それぞれ作動媒体との熱交換で油を加熱する複数の熱交換器71~79を有する。バイパス部9は、膨張機52をバイパスするように設けられたバイパス流路91と、バイパス流路91に設けられたバイパス弁92とを有する。制御部8は、温度測定部21が測定した作動媒体の温度が飽和温度を下回る場合に、バイパス弁92を開放して作動媒体が膨張機52を迂回するように制御する。【選択図】図1
