PURPOSE:A low boiling point medium power generating system which has the structure such as axle seal, etc. compactly simplified by incorporating an intermediate heat medium heater to collect heat from waste heat with a direct type heat exchanger to heat low boiling point medium. CONSTITUTION:Heat in waste heat fluid 1 is made heat exchange with intermediate heat medium in an intermediate heat medium heater 2 and heated, then the heated medium comes into a direct type heat exchanger 7 along with being made heat exchange with low boiling point medium. Here, evaporated low boiling medium is arrived through a system 8 to a turbine 10, which drives a dynamo 11. After steam coming out of the turbine 10 has been condensed by a condenser 13 which is cooled off by a cooling water system 12, it is returned through an intermediate heat medium cooler 15 to said heat exchanger 7. In this case, incorporative structure is made such as to hold said intermediate heat medium heater 2, the direct type heat exchanger 7, the turbine 10, the dynamo 11 and the condenser 13 into one closed vessel. |
