Studying Performance of Fresnel Solar Power Plant with Different Working Fluids

Nowadays due to destructive effects and the increase in cost of fossil power plants, clean and renewable energy has been considered more than ever. Renewable energies have been widely used due to the reduction of CO2 emission and environmental degradation, in recent years; The solar farm method and especially linear Fresnel reflector (LFR) has been of the interest by researchers in terms of thermodynamic performance and economical aspects. in this study by applying a thermodynamic models along with high-precision empirical correlations, a linear Fresnel solar plant with trapezium-form absorbers, consisting several absorbing pipes, is simulated. the model can be employed to investigate the effective parameters on solar plants of these types. The model is proved to have high rate of calculations and high precision. the model is applied for a specific climate conditions (Yazd, Iran) and performance of different oils are investigated. thermal efficiency, generated vapor rate, thermal dissipation and essential pumping power for each type of oil are studied in this study. at the end the most appropriate kind of oil is introduced for the considered city. furthermore, the appropriate oil type for different climate conditions regarding different seasons and different zones of the city is recommended. performance of the Fresnel Solar Plant can be simply evaluated by the proposed model.
