| Abstract: | A 350MW unit supercritical unit encountered the problem of higher temperature and lower pressure of main steam on boiler side during turbine speed-up,which do not fit in with the required parameters during turbine speed-up.In order to solve the problem,a depth analysis was made combining with boiler structural characteristics and operational control.Many method were used such as burning optimization,burner adjustment,feedwater flow control,high and low by-pass control,desuperheater spray system adjustment and reforming,operation management.It bring better effect. |
