Abstract

The molten salt solar tower system 100 is provided for controlling molten salt temperature in a solar rekeiver 130 for effective operation of the system 100 while without degrading physical of molten salt. The system 100 includes two circuits, first 140 and second 150. The first circuit 140 is configured to supply relatively cold molten salt in the solar receiver 130 for heating, and the second circuit I50 is configured to supply a predetermined amount of the relatively cold molten salt in. the fist circuit 140, as and when the temperature of the relatively hot molten salt circulating through the solar receiver 1 30 exceeds a predetermined set temperature value thereof.
