PROBLEM TO BE SOLVED: To provide a two-phase separation Rankine cycle that separates a partial high dryness steam of delivered steam of an expansion turbine depending on the dryness, directly returns gaseous steam with high dryness to a suction side of a heater, passes wet steam with low dryness through a condenser to be liquefied, then pressurizes and compresses it via a liquid pump, guides it together with the previously separated gaseous steam with high dryness to perform gas-liquid two-phase heating, and improves thermal efficiency. SOLUTION: This two-phase separation Rankine cycle comprises the expansion turbine 12 for expanding overheated steam, doing work to the outside, and discharging delivered steam, the condenser 13 for condensing the wet steam of the delivered steam, a liquid pump 14 for pressurizing and compressing condensate coolant, an ejector 10 for separating and sucking part of the delivered steam using the pressurized condensate coolant as driving steam, and the heater 11 for heating the part of the delivered steam sucked and merged with the driving steam in a two-phase state to provide overheated steam and supplying it to the expansion turbine 12.
