Abstract

See full text

A binary power generation device is equipped with the flow path of a medium circulating through a heat exchanger, a turbine, a condenser, and a pump. A method for removing air that has intruded into the flow path of the medium includes: an air intrusion detection step 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 vapor 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 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 of exhausting the gas.
