摘　　要：纯太阳能热发电作为一种能源清洁转换的有效方式越来越受到关注,吸热器作为发电过程中的能量转换装置在整个发电系统中起到了重要的作用。文中分析了吸热器的温度分布,比较了吸热器5种不同结构的温度场。结果表明:球形吸热器最适合用于太阳能热力发电系统,并给出了球形吸热器在不同时间段的温度分布。计算结果可为工程设计和使用吸热器提供参考。As an effective way for energy clear conversion, solar-only thermal power generation attracts more people to pay attention, the heat receiver plays an important role in energy transformation in solar-only thermal power generation. The temperature distribution of heat receiver was analyzed. The temperature fields of five structures of the heat receivers were compared. The calculated results show that spherical structure is available and the most suitable for solar-only thermal power generation. The temperature distributions of spherical heat receiver were simulated in different time period in the whole day. The result can be taken as a reference for design and application of heat receiver.
