摘要
以热力学第一、第二定律为基础,对抛物面槽式集热器进行热效率和火用效率分析,并以LS-2典型槽式集热器热性能测试结果为依据,分析不同太阳辐照及工作温度条件下对应的火用效率;以此结果作为指导,对以等面积槽式太阳能集热场作为辅助热源替代燃煤发电机组不同回热抽汽集成方式的热力性能进行分析比较,得到此类集热场作为辅助热源与燃煤机组回热系统集成的最佳方案。
Thermal and exergy efficiencies of parabolic trough collectors （PTC） were analyzed by the basic laws of thermodynamics. Under different solar radiation and operating temperature conditions, a typical PTC ： LS-2 was analyzed according to its thermal performance test results. approaches was analyzed and compared. The integrated same area as a supplementary heat source to different typical integrated approaches was obtained. Based on this, thermal performance of different integrated approaches were characterized by using the PTC field with extraction of coal-fired generating units. The best option of
