PURPOSE:To improve efficiency by using the steam of water and the steam of a fluid having the condensation heat smaller than that of water at the temperature of a turbine outlet together in a turbine and making the ratio that the steam of water is condensed in the turbine larger than the ratio of the steam of water. CONSTITUTION:The steam of water and the steam of a fluid having smaller condensation heat are mixed at the inlet 11 of a turbine 1 and pass through the turbins 1. The fluid passing the turbine 1 is converted into a liquid by a condenser 2, heated by a condensing pump 3, separated by a separator 4, pressurized by water feeding pumps 6, 7, heated by heaters 8, 9, and returned to individual boilers. When the turbine 1 is operated by this mixed fluid, the condensation of the steam of water having larger condensation heat progresses in the turbine, thus the weighted average condensation heat of the steam composition at the turbine outlet becomes smaller than at the turbine inlet. Accordingly, the lost heat quantity is reduced, and as a result efficiency can be improved.
