文摘

An integrated model is developed for a solar power tower with S-CO2 Brayton cycle. The effects of several key parameters on the exergy efficiency are analyzed. Optimum operation parameters are suggested for the SPT system with a S-CO2 cycle. The maximum allowable temperature is recommended for novel salts used in SPT.
