36 1 Vol136, No11 2009 1 Journal of North China Electric Power University Jan1 , 2009 , ( , 071003) : 以供热机组为例, 利用抛物面槽式集热技术提出多种太阳能与燃煤机组集成方案并 义太阳能热电 转换效率火用效率等评价指标, 应用锅炉变工况和汽轮机变工况热力计算理论, 对不同方案进行热经济性能 分析结果表明: 集成方案不同, 系统的热经济性能不同; 太阳能加热循环工质参数越高, 集成方案的热经 济性能越好最后进行简单成本分析为太阳能与燃煤机组集成方案的选取与实施提供了一 科学依据 : 太阳能; 集成方案; 热电转换效率; 煤耗率; 热经济性 : TM919 : A : 1007- 2691 ( 2009) 01- 0069- 07 Efficiency anylasis on ifferent mo els of cogeneration integrate w ith solar heating system CUI Ying-hong, CHEN Juan ( School of Energy an Pow er Engineering, North China Electric Pow er University, Bao ing 071003, China) Abstract: Several mo els on cogeneration integrate wit h solar heating system w ere put forw ar by parabolic trough solar collector technology . Base on the thermo ynamic calculation metho s of both bolier an turbine, thermal effi- ciency anylasis on ifferent mo els was carrie out , combine with t hermal ecnomy in exes efine such as heat- to- electricity efficiency an exergy efficiency an so on. The results show that the thermal performance is ifferent in if- ferent integrate mo els. The higher the temperature of the w orking flui heate by collecter is, the higher the effi- ciency of the integrate system is. Finally, the anylasis of unit electricity generation cost was given, which can provi e a certain scient ific ecision basis for the choosing an implying of integrate mo els on generation system wit h solar heating system .
