Parabolic trough plant NOORo II
- Client: ACWA POWER
- Country: Morocco
- Contract type: EPC
- Start date: 2015
- Ending date: 2018
Parabolic trough plant NOORo II, Ouarzazate, Moroco.
Following NOORo I, SENER is now beginning the works on NOORo II, which is rated at 200 MWe and has molten salts storage capacity, and in which SENER’s second generation of parabolic troughs – the SENERtrough®-2 system – are being installed, as they are in NOORo III, rated at 150 MWe.
In contrast to the others, this plant will have a central tower with heliostats and a salt receiver, in the same configuration as that successfully applied by SENER at Gemasolar, in Seville (Spain).
- Project description:
- Technology: Parabolic trough collector, SENERTrough®-2.
- Total reflective area: 1,800,000 m2.
- Surface area of the solar field: 700 Ha.
- Turbine power capacity: 200 MWe.
- Number of loops: 425.
- Thermal storage capacity (equivalent hours of turbine operation): 6h.
- Main cooling method: Air cooled condensers.
- HOW IT WORKS
- SENERtrough®-2 collectors
Solar radiation beams on the SENERtrough®-2 collectors which concentrate said radiation in the central tube through which fluid heated to very high temperatures circulates. This fluid, generically called HTF (Heat Transfer Fluid), is in this case similar to oil in composition.
- Steam generator system
The HTF is pumped through the piping system to the steam generator, where it transfers its heat to vaporize water.
- Steam turbine
The turbine is connected to an alternator that generates electric power.
- Electrical transformer
The steam produced under high pressure is used to move the turbine.
- Air cooled condenser
The steam that leaves the turbine is condensed becoming water that is again incorporated into the cycle. Using an air cooled condenser, reduces the water consumption of the plant in more than 80%.
- Heat exchanger
When there is excess thermal energy in the solar field, it is stored. This is done by diverting some of the heated HTF to the exchanger, where it comes into contact with the salts, transferring its heat to them.
- Thermal storage system
To fill up the storage system, cold salt is pumped from the cold-salt tank to the heat exchanger, where the HTF heats it. The salts are then stored in the hot-salt tank.
During discharge, the stored hot salt is pumped to the same heat exchanger to heat the HTF and continue generating electricity even during periods when there is no solar radiation.
