摘要
结合国内外光热发电的发展状况,介绍了我国第一批50MW塔式熔盐光热示范电站的进展动态。介绍了50MW等级塔式熔盐光热电站的工作原理,并介绍了玉门鑫能项目的汽轮机热力系统方案及总体布置方案。为了进一步提高机组性能,降低光热电厂热耗,从进汽压力、进汽温度、排汽压力、回热级数4个方面进行了汽轮机热力系统优化分析。研究成果可为国内50MW等级塔式熔盐光热电站的汽轮机选型提供参考。
Based on the development status of solar-thermal power generation at home and abroad, the progress of the first batch of 50 MW molten salt solar-thermal power plant in China is presented. Its working principle is demonstrated, and the thermal system scheme and general layout scheme of Yumen Xinneng project are discussed. In order to further improve the unit performance and reduce the heat rate, optimization analysis with respect to main steam pressure,inlet temperature, exhaust steam pressure and regenerative series is conducted. The research results can provide references for turbine design of 50 MW molten salt solar-thermal power plant in China.
