【Abstract】 By equipping cylinder to change the fan’s inlet, the configuration of gas-solid two-phrase flow can be changed. Various diameters of cylinder produce various configurations of the flow and affect the degree of erosion and ash in the impeller of the fan. The paper analyzed the reason for giving rise to erosion and ash and the theory of configuration of flow. That provides the basic reference for improving the degree of erosion and ash of centrifugal fan.更多还原
