ABSTRACT:
A turbine system is provided in which a turbine is associated with an auxiliary component such as a moisture separator reheater (MSR) through piping that extends over substantial distance and the respective supports for the turbine and the MSR are subject to differential movement upon a seismic shock. The turbine is rigidly supported on its foundation while the MSR has a floating support on its foundation which includes permanently lubricated sliding plates between the feet of the MSR and the MSR foundation. In addition, viscoelastic dampers are employed at spaced locations between the MSR and structural steel plates that are rigidly attached at one end to the turbine foundation. The dampers allow adequate movement of the MSR for the protection of crossover and crossunder piping due to thermal expansion and contraction, but minimize relative movement of the MSR and the turbine foundation upon seismic loading.
