摘　　要： 介绍了槽式太阳能发电系统的应用与分类,槽式太阳能发电系统分为双回路系统、直接产蒸汽发电(Direct Steam Generation,DSG)系统,对两种系统流程进行了探讨。指出DSG系统主要技术瓶颈集中在接收器,对提高接收器内管(金属管)的热导率、改善接收器周向受热均匀程度、改善内管的润湿性和周向汽液分布的方法进行综述。 The applications and classification of trough solar power system are introduced. The system can be divided into double-loop system and direct steam generation system, and the process flows of both the systems are discussed. It is indicated that the main technical bottleneck of the direct steam generation system lies in the solar receiver. Methods for enhancement of thermal conductivity of inner pipe, improvement of circumferential heating uniformity, the wettability of inner pipe and the circumferential gas-liquid distribution are reviewed.
