Abstract: The reasons of vibration of drainage tubes in heat supply network of two 300MW heat supply units in a power plant were analyzed. Based on this, an improving scheme was put forward, according to which the steam inlet gate of the heat supply network heater had been replaced by adjustable valve, and the drainage electrically operated gate had been replaced by drainage adjustable valve; and the vibration of drainage tubes of heat supply network heater was eliminated.
