Abstract
Solar heat for industrial processes has gathered much attention and technological vision over time due to energy savings and environmental concerns even though there are various restrictions and complications in integrating solar collector technologies with industry. This study aims to cut thermal energy consumption and anthropogenic gas emissions in bulgur industry by proposing a novel experimental design for a solar-assisted process heat (SAPH) system. An experimental method has been addressed for the food treatment process integrated with parabolic trough solar collectors (PTSCs) and the proposed dynamic model of the system has been simulated for predicting the annual performance. The performance parameters of the individual system components have been analyzed during the days of the experiments conducted. Operational experience gained from the application reveals that the overall system efficiency depends keenly on the collector efficiency of the PTSCs used, load characteristics, and operating conditions. Furthermore, selecting an appropriate size for all heat-exchange devices is a critical parameter to improve the overall efficiency significantly and avert long-term temperature fluctuations. The long-term simulation results reveal that the annual efficiency can be obtained as 20.8 % for the SAPH system and further improved with system optimization.
