Control strategy of molten salt solar power tower plant function as

The molten salt solar power tower station equipped with thermal energy storage can effectively compensate for the instability and periodic fluctuation of solar energy, and a reasonable operation control strategy is essential for its peak-regulating operation mode. Based on the law of conservation of energy and conservation of momentum, the

Molten salt power towers operating at 600–650 °C: Salt selection

One limitation of solar salt is a thermal decomposition temperature in the range of 600 °C, which limits the upper temperature of power tower systems employing solar salt as the HTF and thermal storage media. A number of alternative salts have been proposed and explored; for this analysis we focus on the salts listed in Table 1, Table 2.
