Fan foundation dynamic testing

In many cases it is important to assess the existing fan foundations to determine if they are still in good condition. It is also necessary to provide the fan and structural engineers with the dynamic stiffness values to allow them to assess the suitability of the foundations for new fans.  There is often a requirement to upgrade existing large centrifugal induced draught fans to provide higher pressure rises when new boiler flue gas cleaning systems are being introduced, .

It can be cost effective to have new fans operating at a higher speed while using the existing concrete fan supports and the fan casing. In such cases it is of paramount importance that the existing fan foundations be dynamically tested.   This provides the fan and civil engineers the dynamic stiffness parameters to allow them to design the new fan rotor system. We have developed a technique for doing this.
