Aalborg CSP received an order from the Danish utility and energy supply company SK Forsyning to deliver a 8 MWth solar heating plant consisting of flat solar-thermal collectors. The system is integrated with SK Forsyning's existing energy infrastructure - including a biomass boiler - for a more flexible energy supply.
Customized solution for optimum energy utilization
The 11,733m2 solar district heating system consists of 74 rows of highly efficient double-glazed flat solar-thermal collectors. The 74 rows of collectors with up to 38 collectors per row are capable of producing 6,500 MWh heat annually and provcide the district heating plant's 5,000 customers with sustainable heating. The system is adapted to fit the district heating plant’s specific temperature set and energy needs and is therefore optimized for high return temperature as well as low average temperature. Likewise, the system is designed to run low-temperature operation enabling the heating plant’s biomass boiler to be used as a temperature booster.
Optimal use of available land
The solar field is divided in two in order to keep the required distance to a historic burial mound. Aalborg CSP re-designed the entire solar field layout, piping, etc. to keep the necessary distance. As a result, the solar panels are located both north, south and west of the burial mound to make room for the necessary number of panels required for providing the desired amount of energy.
