Power Plant Structures, Machinery & Equipment

– Protection of Power Plant Structures, Machinery and Equipment from vibrations
– Vibration Control
– Elastic support of feedwater pump
– Dampers for piping system

By spring-supported systems …
• the dynamic operation behavior of machinery in the plant is independent of the substructure and soil conditions
• the vibration isolation efficiency, e.g. for turbines is higher than 98 %
• structure borne noise is suppressed
• the layout of the structure and its components becomes more flexible
• provides the basics for standardized layouts & economic savings are provided

Turbine Building:
1) More slender table
2) No expansion / vibration joints
3) Simplification of the structure
4) More slender building
5) Optimization / simplification
