SOLAR HEAT ELECTRICITY GENERATION FACILITY, HEAT MEDIUM SUPPLY FACILITY, AND TEMPERATURE VARIATION SUPPRESSION DEVICE

摘要

A temperature fluctuation suppressing device for heating medium is provided which is capable of sufficiently suppressing temperature fluctuations of the heating medium by the time of supplying collected solar heat for steam generation by suppressing the temperature fluctuation even if the temperature of the heating medium inevitably fluctuates with time. The temperature fluctuation suppressing device includes a heating medium mixer (10) provided on a heating medium supply passage (6) configured to supply a liquid heating medium to a heat exchanging device, the heating medium mixer (10) including: a heating medium passage forming member (29) having plural heating medium passages (30); an inlet member (91) allowing the heating medium to flow into the heating medium passage forming member (29) from the heating medium supply passage (6); and an outlet member (93) allowing the heating medium to flow out of the heating medium passage forming member (29) to the heating medium supply passage (6), the outlet member (93) being provided separately from the inlet member (91), whereby the heating medium continuously flowing into the heating medium passage forming member (29) through the inlet member (91) passes through the plural heating medium passages with time-lags to form respective streams, which are then joined together before flowing out through the outlet member (93).
