Application of Goodrive5000 High Voltage Variable Frequency Speed Regulation System in Induced Draft Fan and Feed Water Pump
Click amount:
Project Overview 

Sinopec thermal power center is equipped with six 25MW coal-fired generating units, the boiler feed pump and induced draft fan respectively adopt 6kV / 2240kW and 6kV / 250kW asynchronous motor drive. During production process, fan and pump are operated in industrial frequency, the flow is adjusted through the fan inlet duct and pump outlet valve, resulting in great energy waste.
