Through analysis of furnace-wall vibration cases for utility boilers in China

it is considered that the furnace-wall vibration is mainly caused by fluid dynamics

combustion dynamics

resonance of furnace pressure fluctuation frequency with acoustics’ natural frequency

as well as insufficient rigidity of the furnace wall. And recommendations and countermeasures have been put forward for boilers’ furnace wall vibration resulting from different causes

having certain reference role for preventing problems of this kind from occurring.
