Abstract: The composition and working principle of circulating water system were introduced. The problems of the unit occurred in winter operation condition were analyzed. The winter operation of the circulating water system was optimized; the LV valve position of the turbine was arranged rationally; related technical measures were drawn up. The house service consumption rate was reduced greatly; and favorable economical benefit was obtained.
