Mathematical Modeling of a developed Central Receiver Based on Evacuated Solar Tubes

Abstract

Abstract. Solar central receiver plays a considerable role in the plant output power; it is one of the most important synthesis in the solar power tower plants. Its performance directly affects the efficiency of the entire solar power generation system. In this study, a new designed receiver model based on evacuated solar tube was proposed, and the dynamic characteristics of the developed receiver were investigated. In order to optimise and evaluate the dynamic characteristics of solar power plant components, the model investigates the solar radiation heat conversion process through the developed receiver, where the energy and mass conservation equations are used to determine the working fluid temperature and state through the receiver parts, beside the calculation and analysis of the thermal losses.

Evaluation of System for Economically Viable Thermal Power Plant Operation

“…It consists of central tower and heliostat field that sends sunbeams to one point on the top of the central tower. On top of the central tower is stationed a solar receiver that transfers heat from the sunbeams to molten salt [10]. Molten salt is a working fluid in the solar cycle because it can withstand high temperatures (exceeding 500 °C) [11] that concentrated sunbeams produce.…”

The Knowledge Mapping of Concentrating Solar Power Development Based on Literature Analysis Technology

“…For different types of CSP, the key components have different structure, characteristic, and performance. In order to optimize the component structure [17][18][19][20][21], improve the mechanical performance, control the accuracy of equipment [22][23][24], improve the energy conversion efficiency [25][26][27][28][29][30][31][32][33][34][35][36], and reduce the Levelized Cost of Electricity (LCOE), researchers around the world have already conducted substantial research on key technology [37,38], applications [39][40][41], system design [39,42], and economics of CSP [13,[43][44][45].…”
