摘 要: 本文对非均匀辐射热流密度太阳能熔盐吸热器传热过程进行了模拟研究,得到了熔盐吸热器内部的温度、传热性能等特征参数。结果表明在轴向和径向上熔盐流体温度和管壁的温度都非常不均匀,同时其综合传热性能要高于按照Sieder-Tate公式的计算值。并对10 MW塔式太阳能热发电的熔盐吸热器进行了设计和分析。 The present study simulates the heat transfer performance of the molten salt receiver with non-uniform radiant heat flux,getting the inner tube wall temperature,heat transfer performance and other characteristic parameters.The results show that the temperature distribution of molten salt and tube wall are very uneven whether in axial or radial direction.The heat transfer coefficient is higher than that of the Sieder-Tate formula.The paper also designs and analyzes a solar thermal power tower with 10MW thermal capacity.
