the causes leading to low performance in operation of centrifugal air fans in one power plant has been studied.The study shows that the influence of flow collector upon the aerodynamic flow field inside the impeller is very large.The bad matching between the flow collector and the impeller can affect the actual performance of air fans
the deviation existing in structures of actual flow collector and designed flow collector is the main cause resulting in low performance in operation of air fans.After retrofitting the flow collector
the performance of air fans in operation reaches the designed value.
