摘　　要：轴流风机发生失速和喘振是电厂运行中的常见故障,严重制约了机组的安全经济运行。在阐述失速和喘振现象的基础上,分析和总结了国内多家电厂不同型号轴流风机发生失速和喘振的原因及相应的处理措施,举例说明了发生失速和喘振过程中运行工况点的变化,并归纳了预防措施。It is common faults that stall and surge emerge from axial fan at operation of power plant,which constraints,to a large extent,safe and economical operation of the power unit.On the basis of explaining the phenomenon of stall and surge,the present paper not only analyzed and summarized the causes and according treatment measures of stall and surge for various type axial fan in many power plants domestically,but also illustrated variation of operating points in stall and surge occurrence processes and induced preventive measures.
