Abstract: PURPOSE:To increase work volume of a turbine by supplying high temperature and pressure steam which is generated during heat recovery, to a high pressure part of the turbine, and mixing a fluid having a high boiling point with a fluid having a low boiling point when low pressure steam is mixed in. CONSTITUTION:A mixed fluid containing ingredients with different boiling points reaches the low pressure evaporator 5 of a heat recovery device 1 as a working fluid, and then mainly its ingredient with a lower boiling point evaporates to be a two phase (vapor-liquid) fluid. The steam mainly containing an ingredient with a lower boiling point which is separated by means of a vapor-liquid separator 6 is introduced into a mixed pressure turbine 12. On the other hand, a fluid mainly containing an ingredient with a higher boiling point is pressurized by a booster pump 8 and supplied to a high pressure evaporator 9. The fluid evaporated thereat is continuously heated to a specified temperature by a high pressure heater 10, and then supplied to the mixed pressure turbine 12 through a high pressure steam pipe 11. In this case, the high pressure steam expands and works at the high pressure part of the mixed pressure turbine 12, thereby decreasing its pressure. Working fluid mixed with the low pressure steam mainly containing the ingredient with a lower boiling point is generated at this point, to work until its pressure drops to the discharge pressure.
