SOLAR HEAT COLLECTION SYSTEM

摘要

In order to reduce the risk of damage to heat exchanger tubes of a high-temperature heat collection device, this solar heat collection system is provided with a low-temperature heat collection device (1) which heats supplied water with solar heat to generate steam, a brackish water separation device (4) which separates a water-steam two-phase fluid generated in the low-temperature heat collection device into water and steam, a high-temperature heat collection device (5) which heats the steam separated by the brackish water separation device (4) with solar heat reflected by multiple heliostats (8) to generate superheated steam, and a heliostat control device (13) which controls the angle of the heliostats such that the metal temperature of the high-temperature heat collection device is less than or equal to a threshold temperature set in order to prevent overshoot of the steam temperature at the outlet of the high-temperature heat collection device.
