Rock wool Piping analisys

Completed study of rockwool production plant that aims to remove the vibrations present in the feed pipe and in the discharge pipe of the jacket cooling of the furnace.

Were carried out the following activities:

  • Thermo-fluid dynamic analysis of the part of the plant affected by the vibrations

  • Creating of a dynamic model (on platform ISAAC Dynamics) able to faithfully simulate the system in all its operating phases and to provide the profiles thermo-fluid dynamic and critical operating conditions

  • Identification of optimal operating conditions and changes to plant layout

Central Tower

Improvement of the new modules that allow you to simulate a solar field with a central tower with heliostats. The layout of the solar field will be sized directly from the tower with the ability to evaluate the losses and shading on the mirrors. We have carried out some test with different solar fields.

Three tank Storage (CSP)

In Marrakech we’ll be presenting a dynamic process model of a parabolic mirror and molten salt CSP plant with three tanks direct storage. This study was carried out in co-operation with the Technical Unit for Renewable Sources of Enea. The model was implemented using the fully dynamic platform Isaac Dynamics. It permits to investigate the real plant behaviour in order to perform a subsequent economic feasibility analysis.

CSP plant with operating procedures of exceptional drainage and refilling in collaboration with UTR of Enea

Definition of the dynamic model of a CSP plant capable of producing about 10 MWe. The model of the solar field is able to simulate well as the normal operating procedures also those extraordinary as draining and refilling. In the power block have been taken into account dynamic aspects such as the evaluation of the time needed for a proper grip of load and connection to the network.

ISCC Model

ISCC MODEL (Integrated Solar Combined Cycle System)

Struttura Informatica has developed, in cooperation with ENEA, a dynamic process model of an innovative ISCC plant (Integrated Solar Combined Cycle plant). The solar field generates more of 40 MWe from solar input and it is coupled with a combined cycle of 155MWe total capacity and located in a sunny Italian region (Sicilia) or in North Africa. It can provide very important indications on the process issues connected with the integration of the newest technologies.

Massa Martana CSP pilot plant

MASSA MARTANA PILOT PLANT

Techint S.p.A. commissioned to Struttura Informatica the development of the dynamic simulator of the pilot solar plant, which is under contruction in Massa Martana (Perugia) by Consortium Solare XXI.
In this pilot plant the linear parabolic trough technology is combined with the use of a heat transfer fluid consisting in a molten salt mixture ( NaNO3 – KNO3 ).
A “stand alone” dynamic simulator has been realized for both functional plant areas:

  • Solar field
  • Water-Steam system

As well as the complete plant simulator.
