PROBLEM TO BE SOLVED: To provide a power generation system to generate the power by recovering low-temperature waste heat while preventing working fluid from leaking outside. SOLUTION: A bottoming cycle power generation system comprises a turbo-pump to boost the working fluid in a low-pressure/low-temperature liquid-phase state 1 to a high-pressure liquid-phase state 2, a heating heat exchanger to heat the working fluid in the state 2 into a high-pressure/high-temperature vapor-phase state 3, a turbine which is concentrically connected to the turbo-pump and expands the working fluid in the state 3 into a low-pressure state 4, a heat-radiating heat exchanger to cool the working fluid in the state 4 into the state 1, and a generator which is concentrically connected to the turbo-pump to generate the power. These components are installed in a sealed container. The heating heat exchanger heats the liquid in the state 2 into the gas in the state 3 by the heat of exhaust gas and liquid at 100-500°C. The turbine is rotated by the work when the working fluid in the state 3 is expanded to the state 4, and generates the power by driving the turbo-pump and the generator by the power.
