Abstract: The parameters and system of booster pump of turbofeed pump in 600MW unit of Baotou Huadian Power Generation Corporation Limited were studied. In the startingup of No.1 unit after overhaul, the cold state boiler water feeding scheme using booster pump of turbofeed pump had been implemented. Until today, the cold state boiler water feeding scheme had been implemented in No.1 and No.2 units four times. Due to implementation of this scheme, the operation time of electric feed pump was decreased, the auxiliary power was reduced, and expected energysaving effects were achieved. The results of this scheme show that the scheme is practical and feasible.

Key words: booster pump of turbo-feed pump, electric feed pump, water feeding scheme, calculation and analysis, theoretical research, optimization, implementation
