摘要:
太阳能辅助小温差热发电系统以工业废热作为第一级热源、太阳能集热器作为第二级热源,循环工质在热源中蒸发并过热后,在汽轮机中膨胀做功,从而驱动电机发电.分析了该系统的工作原理和循环过程,并在理论分析的基础上,进行了系统的热力计算.理论计算结果表明:在循环工质为R717,循环工质蒸发侧相变温度为60℃,冷凝侧相变温度为27℃的条件下,此太阳能辅助小温差热发电系统的总的发电效率可达7.15%,表明该小温差发电装置具有较好的应用前景.
Abstract:
The so lar- assisted therm a l pow er generation system, wh ich adop ted industrial w aste heat as a first-c lass heat source and so lar heat co llector as a second one, drove them oto r to generate e lec tric ity wh ile the overheated c irculating re frigerant expanded in the turbine. Firstly the princ ip le and w orking cycle of th is novel system we re ana ly zed, and then system atic the rmodynam ic calcu lation w as carr ied out on the basis o f the theoretica l ana lys is. Theoretical ca lculation resu lts show that: w hen R717 w as circu lating refr igeran t, evaporating tem pe ra ture of c irculating refrig erant w as 60?? and condens ing temperature was 27?? , the e lectr ic ity generating e ffic iency o f th is nove l system cou ld be up to 8. 73%, w hich ind icated that th is nove l therma l powe r genera tion system has a be tter applica tion prospect.
