Parabolic Trough Power Plant Delingha

The 50 MW solar thermal power plant Delingha is designed on the base of the EuroTrough design.
The collector field consists of 190 loops respectively 9,120 single trough collector elements (SCEs). One solar collector assembly (SCA) consists of 12 solar collector elements which are 12 m long each. The design was adapted to the local wind loads, 1% sloped ground, low temperatures and chinese standards.
The thermal storage allows an operation of the plant with nominal output for 9.5 hours after sunset.
schlaich bergermann partner provided the EuroTrough technology on a licensing basis and actively assisted fabrication and assembly.

Parabolic Troughs

Proven state of the art for CSP

Over the years, sbp sonne developed and licensed three different types of parabolic trough collectors: the EuroTrough, the HelioTrough and the UltimateTrough. We are now focusing on the distribution and commercialization of the ‘HelioTrough’ and ‘UltimateTrough’, as these collector developments have been proven to significantly reduce costs and improve performance for large scale power plants.

The UltimateTrough collector for Concentrating Solar Power (CSP) plants is the world’s largest and most advanced parabolic trough collector. Measurements indicate that efficiency of the UltimateTrough is over 10% higher as compared to the benchmark collector.
