Summary:PURPOSE:To improve the avaliability factor of a power generating plant by removing dissolved oxygen in a water feed system efficiently for operation without filling an oxygen scavenger such as hydrazine or the like, in circulating feed water of the power generating plant. CONSTITUTION:In a power generating plant in which steam discharged from a turbine device 20 is condensed and liquefied in a condenser 3 so as to form condensate which is evaporated again thereafter and then the steam is returned to the condenser 3 through the turbine device 20, a hollow thread 16 for deoxidation is provided in a vacuum container 21 subjected to suction-vacuum by a vacuum pump 2, and a hollow thread film deoxidation device 15 which is formed as a feedwater passage is provided in the hollow thread 16 for deoxidation so as to discharge dissolved oxygen in feedwater through the pipe wall of the hollow thread 16 for deoxidation, in the lower steam side of the condenser 3.
