| Abstract: | The obvious vibration exists on the condensate recycling pipeline of ultra-supercritical unit 2 in Tianjin SDIC Beijiang power plant, through field observations and measurements, the reasons of the pipe vibration was ana- lyzed, combined with the pipeline modal analysis, the limit bracket in appropriate place was added to increase the stiffness of the pipe, and improve the natural frequency of the pipeline. The practice has proved that the treatment is feasible, the elimination of vibration effect is obvious. |
