Abstract
Concentrated solar power is one of the most promising and competitive ways to generate energy by using incident solar irradiation. Among the existing technologies, Linear Fresnel Concentrator (LFC) uses the principle of solar concentration for producing useful heat in medium and high temperature applications (>150 °C). The LFC system, when compared with other solar concentration technologies, presents a satisfactory thermal and optical performance and low-cost. Besides that, the LFC appears as a viable solution due to its simple and flat structure and easy maintenance. However, it is still necessary to investigate and understand the progress of research in this field and the current state of art to improve the LFC performance. Thus, the objective of this study is to present a review of research in this field to enhance the performance and the current state of art of LFC designs and applications. Moreover, this work presents the research and projects in Brazil, where this technology is not so consolidated yet and needs to be further explored, both in terms of experimental and theoretical studies, since the country is located geographically in an area with high Direct Normal Irradiation (DNI). For this review, some of the main characteristics of LFC systems are considered, such as the mirror field, type of the receiver and absorber, and the heat transfer fluid used in each case. The orientation and the performance of the LFC system are considered, and an evaluation of characteristics from operational LFC power plants is presented. From the survey of the current state of the art, a discussion of LFC systems in order to build an approach from the scenario of this technology is made and the findings are summarized. Finally, the current trends and the future challenges in the research and development of LFC technology are highlighted.
