<p>Disclosed is a steam power cycle device wherein a part of a working fluid in a high-temperature liquid phase separated from a gas phase by a gas-liquid separator is mixed with a working fluid in a high-temperature gas phase extracted from an expansion machine, and is heat-exchanged with a working fluid in a low-temperature liquid phase discharged from a condenser, so that the heat stored in the working fluid can be efficiently recovered, and the heat efficiency of an entire cycle can be improved. A part of a working fluid in a high-temperature liquid phase separated from a gas phase by a gas-liquid separator (11) is extracted, and is mixed with a working fluid in a high-temperature gas phase extracted from between the stages of an expansion machine (12) at a second absorber (17), so that a part of the working fluid in the gas phase is absorbed by the working fluid in the liquid phase, and the high-temperature working fluids are used to heat the working fluid in the low-temperature liquid phase at a first heater (18). The extracted working fluid in the high-temperature liquid phase is not passed through the condenser (13) and, accordingly, the heat exchange at the condenser (13) is reduced to reduce the load of the condenser (13), and the heat stored in the working fluid in the high-temperature liquid phase can be appropriately recovered by being heat-exchanged with a working fluid passing toward an evaporator. Thus, the heat efficiency of the entire cycle can be improved.</p> |
