摘要:

摘要:塔式太阳能热发电系统相对管式吸热器而言具有结构简单、高参数、高效率、易于维护等优点。其主要传热过程发生在吸热器内部的多孔介质吸热体内,经过聚光的入射辐射加热多孔介质,再通过对流传热将空气加热。介绍了塔式空气吸热器的原理、特点、分类情况以及发展现状,论述了以空气为传热介质的不同类型空气吸热器内对流-辐射耦合传热过程的特点,指出了塔式空气吸热器技术的发展方向。

Abstract:Compared with the tube receivers,the tower solar thermal electric power system has the characteristics of the simple structure, high working parameters, high efficiency,easy maintenance and so on.The heat transfer process mainly occurs in the porous media of the air receiver.The incident radiation heats the porous media, then the air will be heated by convection.In this paper,the principle,characteristic,classification and the development status of the air receiver are introduced.The characteristics of the heat transfer by radiation convection with the air as the heat medium in the different air heater are discussed, and the development direction of the air receiver is also given in this paper.
