Soltigua collectors for Europe’s largest solar district heating for industry
In December 2014 Soltigua completed the installation of 36 PTMx parabolic trough collectors for the concentrated solar district heating system realized in Forlì by the company Forlì Città Solare. The solar field has a net collecting surface of more than 2'800 m2 and a peak output of more than 1.4MW thermal, the highest in Europe for concentrated solar district heating. The collectors will generate heat at 175°C which will be used by several industrial users in the surroundings.
The collectors have been delivered in only few months, exploiting the capacity and the flexibility of Soltigua’s manufacturing system. Installation took only 3 actual months, a result made possible by the design of PTMx parabolic trough, which has been optimized to simplify on-site assembly and maintenance.
“We are glad for this result, which we consider the starting point for offering more and more competitive solutions” – says Ing. Vittorio Orioli, responsible for Soltigua’s technical developments– “This installation proves the merits of using PTMx in solar fields of several thousand square meters, such as the ones required to serve remote industrial sites such as the mines of Chile, to whom we are already providing our technology.”
Soltigua FLT10v Fresnel collectors chosen for a CSP plant in Morocco
Soltigua’s FLT10v linear Fresnel collectors have been chosen for realizing a 1MWel CSP system in IRESEN’s Green Energy Park in Benguerir, Morocco, which has been awarded to the Italian EPC contractor Enerray s.p.a., from the Maccaferri Group. Soltigua will supply n.28 of its FLT10v linear Fresnel collectors for a total collecting surface of 11'435 m2. The solar field will be made of 7 parallel hydraulic loops, which will generate heat at 300°C to drive a dry-cooled 1MWel ORC turbine provided by Italian ORC manufacturer Exergy, also part of the Maccaferri Group.
The Benguerir installation will pilot a new concept for small scale CSP, focusing on a decentralized solution with short execution period and a system that is compact and modular, to achieve economies of production and to meet local customer needs with less than 10 MW combined heat and power requirement. The aim of this pilot project is to construct a reference design on which additional solutions will be integrated, such as storage for power production extension, heat extraction for cooling and/or desalination.
“We are enthusiast to contribute to the development of this new CSP concept, which is fully in line with Soltigua’s philosophy of agile, modular collectors and systems” – says Francesco Orioli, Head of Sales at Soltigua – “We see Western Africa as an area with a great potential for small scale CSP system which can be of great help to serve also the thermal needs of several types of industrial processes”.
The installation of Soltigua collectors will be done during 2015.
