WATER FEEDING METHOD, WATER FEEDING SYSTEM IMPLEMENTING SAID METHOD, AND STEAM GENERATING FACILITY PROVIDED WITH WATER FEEDING SYSTEM

WIPO Patent Application WO/2017/018154

A1

A water feeding system (50) is provided with: a first water feeding line (51) through which first feed water flows; a second water feeding line (52) through which second feed water having a lower pressure than the first feed water flows; a first heat exchanger (32) which heats the first feed water; a first feed water introducing line (53) which leads first heated feed water, which is the first feed water that has been heated by the first heat exchanger (32), to the second water feeding line (52); a medium heat exchanger (24) which causes the first heated feed water to exchange heat with a medium, thereby cooling the first heated feed water and heating the medium; and a cooling water injecting line (151) which injects cooling water having a lower temperature than the first heated feed water, in a position in the first feed water introducing line (53) on the second water feeding line (52) side of the medium heat exchanger (24).
