Field Test of Superheater Pipes Vibration Caused by Sound Energy in the 235 MW<sub>e</sub> Circulating Fluidized Bed Boiler

This paper presents the results of measurements of vibrations of the pipes of the steam superheater installed in the convection pass of the 235 MW<sub>e</sub> Circulating Fluidized Bed boiler (CFB) induced using sonic soot blowers of the Nirafon NI-100 type. The measurements were made us...
