Abstract:

To save startup energy and shorten boiler startup time, high pressure reheater was put into operation in advance in startup stage. Due to small water flow and full cold state, dewater pipeline usually serious vibrates during startup. After analyzing vibration causes, technical improvement was carried out accordingly. Vibration of high pressure reheater in startup stage was eliminated.
