A method for operating a solar thermal power plant (100) comprising multiple solar radiation receivers (1) operated using a molten salt as the heat transfer medium, wherein each solar radiation receiver (1) comprises a reflector device (3) and an absorber tube (5), comprises the following steps: - preheating of the absorber tubes (5), in the state in which said tubes are empty of the molten salt, to a temperature T by concentrating solar radiation on the absorber tubes (5) by means of the reflector devices (3), wherein the temperature T is greater than or equal to the melting temperature of the salt; after reaching the temperature T: - introduction of the molten salt into the absorber tubes (5) and recirculated conduction of the molten salt through the absorber tubes (5) while simultaneously repositioning the reflector devices (3) depending on the position of the sun; on ending the operation: -release of the molten salt out of the absorber tubes (5). |
