Technique Analysis of Variable Frequency Reconstruction on Motor of Booster Fan in Gas Desulfurization System
This paper finds out the optimum operation condition of the stator blade variable axial flow blower by analyzing the operation characteristics of the booster fan in Gas Desulfurization System of the Coal fired power plant.Via analyzing the direct proportion between rotate speed and power frequency of the 3-phase induction motor,gets the conclusion that the range of speed regulation will be wider and the rotate speed curve will be smooth if the motor＇s speed is stepless regulated by frequency converter.Makes a presentation of the theoretical analysis and the experience of the reconstruction of Motor of Booster Fan in Gas Desulfurization System of FYCRP 600MW Supercritical power plant,states that after the reconstruction,the energy consumption of the Gas Desulfurization System is reduced observably,the speed regulation performance of the motor is improved,observable energy conservation effect and economic benefit are gained.Some issues related to the protection design and operation of the frequency converter-fed speed regulating system is also stated in this paper.
