MACOGA delivers Expansion Joints for 4.26 MWE Concentrated Solar Plant in Sicily

MACOGA delivers Expansion Joints for 4.26 MWE Concentrated Solar Plant in Sicily 

The sun radiation is the main energy resource of our planet, and several technologies are currently available to exploit it, among them the Concentrated Solar Power (CSP) is very important. 

The sun rays are concentrated by special mirrors on a receiver, heating a vector fluid made by molten salts up to ~550 C°. The vector fluid transfers the heat to the steam cycle that produces electricity by a Steam Turbine. The vector fluid can also be stored in special tanks at high temperature allowing the production of energy even in the absence of sun. 

The plant will be located in the Partanna Municipality in Sicily and will occupy about 110,000 m², the surface of the mirrors will be 83,200 m². 

The steam turbine power size will be 4.26 MWe. The thermal energy storage will have a capacity of 15-hour operation and the annual energy production will be around 19 GWe. 

Mechanical design, parameters and features of the expansion joint supplied are: 

  • Type: Elbow Pressure Balanced MPB-E
