Optimization Dispatching And Application Of Circulating Water Pump

The operation optimization of the coal-fired unit is the key power saving method through the power saving analysis and diagnosis. The circulating water pump is one of the most energy cost equipments; it will affect the vacuum of the condenser and the station service power consumption rate. The research on optimization operation of the circulating water pump is the important field. Most of the coal-fired units applied the fixed-speed circulating water pump, and the circulating water flow will be controlled by changing the Combination running mode. When the external conditions changed, the maneuvering condition calculation of the condenser and cooler tower will be studied to introduce the power saving operating mode of the circulating pump. The calculating steps of the optimization operating then are introduced and the optimization system is running in a practical unit. The statistics data illustrate the power saving result.
