PROBLEM TO BE SOLVED: To provide a power generating device by steam which can substantially reduce equipment depreciation period thereof. SOLUTION: A high pressure process steam supply pipe 1 is branched to be connected with a vapor expansion unit 2. An outlet side of the vapor expansion unit 2 is connected to a steam utilization device 3. The vapor expansion unit 2 communicates with a power generator 10. A condensate tank 13 is connected to the lower part of the steam utilization device. The top of the condensate tank 13 is connected with a suction port 15 of a steam ejector 4 through a pipeline 14. The outlet side of the steam ejector 4 is connected to the steam utilization device 3 through a pipe line 17. A liquid force-feed member 19 is disposed at the lower part of the condensate tank 13. High temperature condensate formed by condensing steam by the steam utilization device 3 flows down to the condensate tank 13 and is re-vaporized to become re-vaporized steam, which is sucked in the steam ejector 4 to be supplied to the steam utilization device 3 again. By so doing, energy efficiency of the whole power generating device can be kept high, and further equipment depreciation period of the power generating device can be substantially reduced.
