| Abstract: | Comparison is made about the operating mode and economy efficiency of condensate pump between constant-speed scheme and frequency control scheme for 9F combined cycle unit. The curves of condensate pump mean annual cost to the price of natural gas and to the mean annual load rate of unit are established. The problems after adopting condensate pump with frequency control scheme are analyzed, and the reasons for mostly choosing constant-speed scheme at present are given. |
