Abstract: The booster fan is important device for performance and reliability of desulfurization system, its type selection has greater influence on the overall cost and performance optimization of desulfurization system. The economic and technical comparison between axial-fan with adjustable moving vanes and axial-fan with adjustable static vanes were given from the aspects of performance parameters, power consumption, maintenance and cost. The conclusion of this research can be used as a reference for booster fan selection of FGD engineering.
