摘　　要：Cyclone separators are separation devices that use the principle of inertia to remove particulate matter from flue gases.The present study mainly focuses on wall erosion in cyclone separators and associated research.The main locations of erosion in gas–solid cyclone separators,including the entrance impact section,cyclone roof corner,vortex finder outer surface,spiral-type erosion strip,and lower cone section,are examined in detail.The main factors influencing wall erosion are discussed,including inlet flow velocity,solid particle properties and loading,geometrical structure,and manufacturing quality.Finally,several practically preventive measures against wall erosion are presented,including adjustment of operating conditions,the use of erosion-resistant materials,optimization of geometrical structures,and the addition of auxiliary devices,all of which are essential for ensuring operational efficiency,equipment reliability,safety,and environmental protection in various industrial applications.This paper aims to provide a basis for further research into erosion in cyclone separators as well as guidance for engineers involved in their industrial applications.
