Two kinds of representative CC-Repowering (feed water heating repowering,full firing repowering) were analyzed and compared in this paper. Aremarkable phenomenon was observed: Efficiency monotonouslychanges with work-ratio in FF-Repowering system; but in FWH-Repoweringsystem, there exists an optimal ratio at which point the efficiency isthe highest. Another phenomenon to be paid attention is that under somework-ratio, the efficiency of FWH-Repowering is higher than that ofFF-Repowering, giving rise to correcting the conventional concept.
