Abstract

AbstractIn this experimental research, the recovery of exergy from a Scheffler collector is assessed where a receiver cum spiral absorber tube of mild steel of size, 0.025 m diameter and 10 m length was tested at various Direct Beam Radiations (DNI) (500, 600, 700, 800, and 900 W/m2) and mass flow rates of water (400, 600, 800, 1,000 and 1,200 kg/hr). For this aim, the heating of the flowing water is performed through the receiver, installed at the fixed focus of the collector. As a significant consequence, by rising the DNI and mass flow rate, the recovered exergy enhanced. Further, the increment of the exergy factor because of the utilization of the recovered exergy from the Scheffler collector has also been investigated in this paper. The results demonstrate that by utilizing the recovered exergy, the exergy factor increased approximately 36.18%. The outcomes of this research article are also validated with the “solar parabolic dish concentrator” to set the novelty of the work.
