Approach of Energy Saving and Consumption Reduction of Circulating Water Pump and Its Application

The circulating water system in Huadian Laizhou Phase I Project adopts once-through water supply system using seawater as the water source. According to the characteristics that seasonal air temperature changes, microorganism reproductions and tidal differences would cause substantial increase of the circulating water temperature and volume at the same loads and time the comprehensive analysis and optimization are conducted in the aspects such as periodic half side flushing, circulating water pump operation modes and circulating water system users and the optimal operation mode is obtained, which enables better energy saving and consumption reduction.
