摘要
通过分析700 MW机组一次风机并列时多次发生失速原因,找出存在的隐患,并通过改进措施,使一次风机运行的可靠性得到提高,同时可以减轻风机失速对机组运行的影响。
By analyzing the stall failure of axial flow primary air fan in 700MW unit,it was found that the probability of stall caused by defects lying in the thermal system can be effectively reduced.These measurescan simultaneously minimize the influence of airfan stall on operation of the powerunit.
