PURPOSE:To aim at a reduction in plant power without necessitating any power for hydraulic fluid circulation, by combining a plural-step bubble booster pump, which installs a hydraulic fluid suction pipe in a lower drum at the first step and an exhaust pipe in a condensing chamber at the final step, respectively, with an evaporator, a turbine and a condenser. CONSTITUTION:A hydraulic fluid being liquefied in a condenser 5 is led into a bubble booster pump 7 at the first step and heat-exchanged with a heat source fluid system 102. Then, air-liquid separation takes place at a condensing chamber 11, while vapor is liquefied and fed to a lower drum 15 at the next step. After similar operations are repeated at each step in regular sequence, the hydraulic fluid in the condensing chamber 11 at the final step is led into an evaporator 2 and, after a turbine 3 is rotated by the steam, it is liquefied again at the condenser 5. Thus, since a circulating pump can be made into useless, it can dispense with pumping power any longer. |
