| Abstract: | The closed loop cooling tower is adopted for the circulating water cooling of a 600 MW power unit and the house power of the circulating pump was 1.0 percent.To further reduce the house power consumption of the circulating pump,a frequency conversion retrofit has been made so as to achieve a continuous adjustment of the circulating water.Based on test results obtained after retrofit,an optimization scheme is proposed for operation of the retrofitted circulating pump of a 600 MW power unit. |
