摘要：The experimental testing shows the construction and testing of three parabolic trough solar collectors (PTSC) experimentally in order to produce moderate-temperature steam. The experimental investigation was carried out on PTSC to testing the thermal performance of the system. The tests were carried out at University of Kerbala / college of engineering with climatic conditions (32.34o N, 44.03o E) for nine days during the month of July and August of 2018. Different parameters of the PTSC system are selected for testing this study such as heat transfer fluid (HTF) type (hydraulic oil, ethylene glycol, and water) and three flow rates of working fluid (1 LPM, 2 LPM, and 3 LPM). A process of steam generation was occurring with a steam temperature of 95.4oC and steam pressure of 2.1 bar. The experiments show that the maximum heat gain and high efficiency can be occurring with using hydraulic oil and the highest value of fluid flow rate. The results show that the maximum useful heat gain is 1.035 kW, 0.879 kW, and 0.734 kW for the case of using hydraulic oil, ethylene glycol based water, and water respectively, with 3 LPM flow rate. The peak experimental efficiencies close to 33.2%, 28.5%, and 22.7% were obtained for PTSC with hydraulic oil, ethylene glycol based water, and water respectively at the highest value of fluid flow rate.
