摘要
选取槽式和塔式两种太阳能热发电系统为研究对象,运用生命周期方法(Life Cycle Assessment,LCA)分别对槽式和塔式太阳能热发电进行系统、全面的环境影响评价。主要对两种太阳能热发电的用材、生产和运输3个阶段进行分析,分别计算了3个阶段的单位能耗和环境影响,并对两个系统的分析结果进行比较。同时,采用朗肯循环对两种系统进行了热效率方面的比较。
Environment effects of trough and tower power generation system can be evaluated by Life Cycle Assessment. Three stages such as raw materials extraction, production and materials transportation were analyzed, energy consumption and environment impact in each stage were calculated, and the results were compared as well. At the same time, two systems were compared with Langken circle. The results showed that trough solar thermal power generation had less effect than tower on environment, while tower solar thermal power generation had more efficiency, and made better use of solar.
