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.
Highlights
The field is planned to collect a maximum number of 20Kw/m2 of solar radiation in the top of the tower, where the receiver will be located
Where the drum inlet flow rate and circulation water flow rate are a control variables, there values are determined according to the rate of the collected solar radiation
The mathematical model of a new designed central receiver performance based on evacuated solar tube configuration has been developed
Summary
MATEC Web of Conferences present a modeling and simulation of the plant central receiver system. The heliostat field layout design HFLD software is used to calculate the performance of the plant, and TRNSYS plant model is developed for the plant simulation. The field is planned to collect a maximum number of 20Kw/m2 of solar radiation in the top of the tower, where the receiver will be located. The first phase of the receiver is planned to operate a 1.2 Kw steam turbine. The main component and parameters of the receiver are the number of the used evacuated tube, which decide the interception area of the heat surfaces, the dimensions of the tubes and the arrangement of the tubes and steam separator, Figure (1) shows the developed receiver feature
