塔式聚光太阳能电站有可能达到比抛物线槽式电站更高的温度。这些较高的温度允许更高的电力循环效率，因此使电力塔成为一个有吸引力的选择和日益增长的研究主题。一种常见的设计是将水泵入塔中，使其沸腾，并以饱和或过热蒸汽的形式返回电力循环。提高直接蒸汽系统的动力循环效率的一种选择是将蒸汽从高压涡轮机排出，通过一个指定的再热接收器部分，然后通过低压涡轮机。本文详细介绍了由专用锅炉、过热器和再热器组成的直接蒸汽接收器的一种新的半经验第一性原理热模型。将该热模型与SAM中的回归功率循环模型和定日镜场模型相结合，对直接蒸汽动力塔式聚光太阳能电站的性能进行了模拟，并给出了分析结果。©2012 asme
Power tower concentrated solar plants have the potential to reach temperatures higher than those achievable by a parabolic trough plant. These higher temperatures allow for greater power cycle efficiencies and therefore make power towers an attractive option and a growing topic of research. One common design is to pump water through the tower such that it boils and returns to the power cycle as saturated or superheated vapor. One option to increase power cycle efficiency for a direct steam system is to send the steam exiting the high pressure turbine through a committed reheat receiver section and then through a low pressure turbine.This paper details a new semi-empirical, first-principles thermal model of a direct steam receiver consisting of dedicated boiler, superheater, and reheater sections. This thermal model — integrated with a regression power cycle model and a heliostat field model in SAM — is used to simulate the performance of a direct steam power tower concentrated solar plant and the analysis results are presented.© 2012 ASME
