摘　　要：文中介绍了现有塔式太阳能热发电吸热器技术,针对不同吸热器结构和传热介质,结合国内外现有主要塔式太阳能热发电站,对吸热器性能进行比较研究。结果表明,外露管式吸热器结构简单、造价低,应用广泛;而熔盐作为传热和蓄热介质具有较好的性能,系统无压运行且能承受高热流密度,是将来的研究方向。This paper introduces the technology of the existing solar center receiver. Comparisons of different receivers and heat transfer fluid are made on the performance with the main solar power tower inland and overseas. The result shows that external tubular receiver features more simple structure and lower cost, which lead to more abroad application. As the heat transfer and heat store fluid, molten salt has better performance. The system is nearly at atmospheric pressure and can afford much higher incident solar fluxes, which is to be the direction of research.
