A power generating device equipped with an air removing device for detecting air that has intruded into a medium flow path of the power generating device and automatically removing the intruded air. A binary power generation device is equipped with the flow path of a medium circulating through a heat exchanger, a turbine (101), a condenser (103), and a pump (104). A method for removing air that has intruded into the flow path of the medium in the binary power generation device (102) is characterized by sequentially performing: an air intrusion detection step (S1) of calculating, based on the pressure and temperature of a gas retaining portion communicatively connected to the flow path of the medium, a pressure threshold value obtained by adding the saturated vapour pressure of the medium and a margin value and of detecting, by comparing the pressure of a gas phase portion with the pressure threshold value, that air has intruded into the medium; a medium liquefaction step (S2) of producing a gas by pressurizing a mixed gas of the medium and air to reduce the amount of the medium in the mixed gas; and an exhaust step (S3) of exhausting the gas. |
