| Abstract: | The tube bundle vibration problem, often occurring during operation of the waste heat boiler, has been analyzed. Measures have been put forward on the structural arrangement so as to prevent waste heat boiler vibration, such as adopting a rational choice of flue gas flow rate, adding anti-vibration partitions, increasing tube constraints and changing the bundle structure, etc. |
