In 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.

通过Scheffler集热器从水加热中回收火能，获得更多的火力因子

在这项实验研究中，我们评估了Scheffler收集器的火用回收率，其中，在各种直接束辐射（DNI）下测试了直径为0.025 m，长度为1025 m的低碳钢的接收器兼螺旋吸收管（500，600， 700、800和900 W / m ²）和水的质量流量（400、600、800、1,000和1,200公斤/小时）。为此，通过安装在收集器固定焦点上的接收器对流动的水进行加热。显着的结果是，通过提高DNI和质量流量，回收的火用能提高了。此外，本文还研究了由于利用了从Scheffler收集器回收的本能而引起的本能因数增加。结果表明，通过利用回收的火用能，火用因子增加了约36.18％。该研究文章的成果也通过“太阳能抛物面碟式浓缩器”进行了验证，以设定这项工作的新颖性。
