Countermeasure for High Level Sound Generated from Boiler

Heat exchangers and boilers are widely used in various plants such as power plants and chemical plants. In the heat exchanger and the boiler, a high level sound is sometimes generated from the tube bank installed in a duct. In tube banks, warm gas flows outside of the tube, and due to the external flow around tube banks, the Karman vortex shedding occurs.

Managing Flow Induced Vibration in Boilers

Flow induced vibration in boiler occur when the vortex shed by the passing flow coincides with the natural frequency of the component or the gas column. The vortex shedding frequency manly depends on the tube bundle arrangement adopted. Both the transverse and longitudinal pitching play an important role in deciding the vortex shedding frequency.
