摘要
针对国电大同三期660 MW机组在RB过程中一次风机失速的问题,在轴流风机失速机理的基础上,根据实测数据对一次风机失速的原因进行了分析,通过采取一系列改善措施,不仅确保了RB功能的实现,也提高了一次风机运行的安全性及可靠性。
Aiming at the problem about primary air fan stall during RB working condition of Guodian Datong Power Plant phase Ⅲ project,the reasons of primary air fan stall is analyzed according to the principle of axial fan stall and measured data.Adopting series of improvement,not only assured the implementation of RB function,but also improved the reliability and safety of primary fan.
