Design and thermal performance analysis of concentrating solar power
However, converting solar energy into thermal energy in a small-scale application using CST technology is challenged. As the technology uses many mirrors (heliostats) to gain a high-efficient working system, the small scale would be inefficient due to the inconsistent design criteria [19].Receiving the solar radiation by the heliostats and redirecting it into the tower''s
Thermal design guidelines of solar power towers
One of the main problems of solar power tower plants with molten salt as heat transfer fluid is the reliability of central receivers. The receiver must withstand high working temperatures, molten salt corrosion and important solar flux transients that lead to thermal stresses and fatigue.
