太阳能电站中涡轮机的研究
|
摘要
本文的研究工作是内蒙自治区科技创新资金的一部分,主要研究的是太阳能热气流电站中的涡轮机部分,对其工作性能和基本参数进行初步设计和优化计算。
首先对50KW的涡轮机进行了特性分析。针对100KW太阳能热气流电站系统,对涡轮机进行初步设计及整体研究,选出每种叶片数对应的最佳情况,再综合比较不同情况之间的优劣,从而选出对应于太阳能塔囱电站最实用的涡轮机。提出一套计算太阳能涡轮的计算方法,解决太阳能电站中涡轮机的设计问题。并分析了它的性能参数变化情况,而且还对结果进行了验证,证明了设计与研究方法的有效性。在对初步设计的涡轮机研究的基础上,针对涡轮机叶片自身的一些影响因素,如叶片数目、叶片型式、扭转角度和安装角度等方面,对其进行了一系列的研究,并对各种影响因素进行综合的分析。这为后续的涡轮机设计奠定了一定基础。
在100KW太阳能热气流电站中涡轮机的研究基础上,对100MW的太阳能塔囱电站中的涡轮机又进行了初步设计。确定了32台涡轮机的基本数量,并环形布置在塔囱底部周围的设计方案,并对其中一台涡轮机进行了设计、研究工作,对其性能进行了分析和评价。
本文的研究工作是为了提高太阳能热气流电站的能量转化效率,使其具有更高的优越性,从而加速太阳能电站的推广和使用。为大规模使用太阳能热气流发电提供了依据。
