Abstract

See full text

The inventive solar heat collection system reduces the risk of damage to heat transfer pipes of a high-temperature heat collection device. The low-temperature heat collection device (1) heats water by sunlight heat to generate steam. The steam-water separation device (4) separates a water-steam two-phase fluid generated in the low-temperature heat collection device into water and steam. The high-temperature heat collection device (5) heats the steam separated by the steam-water separation device by use of heat of sunlight reflected by a plurality of heliostats (8), thereby generating superheated steam. The heliostat control device (13) controls angles of the plurality of heliostats so that metal temperature of the high-temperature heat collection device is maintained not to be higher than a threshold temperature set to prevent overshoot of steam temperature at an outlet of the high-temperature heat collection device.
