Sensitivity study of thermal performance characteristics for indirect steam generation in parabolic dish collector

摘要

The advancement in Parabolic Dish (PD) technologies has led to the development of steam production and efficient solution that utilizes the sun's energy for thermal power generation. In this work, a Parabolic Dish (PD) is analyzed for indirect steam generating systems. Parametric studies of the hydraulic systems, the thermal performance and the indirect steam produced were evaluated in the Research and Technology Center of Energy in Borj Cedria of Tunisia (CRTEn). As results, the optimum outlet temperature of the PD absorber is equal to 80°C at noon and the thermal energy efficiency of receiver varies from 70 % to 92 %. The maximum value of the steam generated by parabolic dish is 6 kg/h.
