| Abstract: | Aiming at the existing issues such as the limited adjusting margin, high house service rate and poor economic performances of the circulating water system of a power plant, the modification on the circulating water system is carried out and the testing studies on the micro increase output, the cooling water flow rate and power consumption of the circulating pump under different working conditions and the variable conditions of the condenser are also conducted. Through the studies, the economic operation mode of the circulating water system is obtained, which can ensure that the steam turbine operates at or close to the optimal vacuum. |
| Keywords: | steam turbine circulating water system modification micro increase output economic operation |
