SGS3 steam generator systems - thermal oil
Relying on nearly 30 years of experience within the general boiler industry, Aalborg CSP A/S has developed a value-adding and innovative steam generator design that has a positive impact on levelised cost of energy (LCOE) of CSP power plants.
Value-adding engineering design
The steam generators using thermal oil as heat transfer fluid (HTF) are all developed based on traditional boiler principles. They are therefore 100% welded header and coil type with up to 4.5mm thick tubes, designed according to ASME and EN standards. This contributes to many operational benefits compared to the TEMA standard kettle- and shell & tube-type heat exchangers and therefore has the potential to reduce LCOE of CSP plants by up to 5-10%.
- Leakage-free design: By eliminating operational mistakes and risk for downtime, productivity, electricity earning and the general payback time of the power plant is greatly improved. As a result of excellent performance track records, Aalborg CSP launched a new standard in the concentrated solar power (CSP) industry by announcing a 5-year guarantee against leakages for the new SGS3 steam generation systems.
- Rapid ramp-up of 9 °C/min: The SGS3 can allow a fast ramp-up every morning and at transient clouds. The rapid start ensures more than 30 minute extra energy production of a 9-hour daily operational time and increase daily revenue accordingly.
- Low pressure drop of 1-2 bar: As the SGS3 design is based on traditional boiler technology with tubes of large diameter, it generally has a low pressure drop on the HTF side and can be pushed down to as low as 1 bar.
Constructability & easy installation
The general principle of constructability characterizes the design of our steam generators to minimize installation work on site and the economies associated with it. The SGS3 boiler systems are all developed to perfectly fit into the plant layout. They are prepared for direct mounting on site, and interconnection piping is also pre-fabricated to reduce the time spent on installation.
Fully optimized steam systems
Aalborg CSP places great emphasis on monitoring performance track records of its technologies in order to continuously optimise their effectiveness. Focusing on design excellence, the steam generators have undergone several optimisation practices since the first installation. The SGS3 line is the third, fully optimised edition characterised by increased efficiency and higher reliability.
Secured to be delivered
As a Danish company, Aalborg CSP A/S has the advantage of arranging loan guarantee through a Danish state owned export credit agency. The agency insures banks against the potential financial and political risks – thereby securing the loan and delivery of our SGS3 steam generation systems without financial obstacles.
