ABSTRACT

Experimental data on superheating during sodium boiling-up in a high-temperature receiver-evaporator, receiving concentrated solar radiation, has been analyzed for the first time. The relationship for calculation of the onset of boiling depending on the saturation temperature (pressure) and the heat-flux density has been obtained. This was used as the basis for evaluating the impact of nonuniformity of a nonstationary heat flux on the temperature field of the evaporator.
