Prospect of Solar Thermal Power and Experimental Research of Parabolic Trough Thermal Collector

Solar energy is a key solution to China's energy supply in the future.Solar parabolic trough power generation is a technology-mature and economy-feasible solar thermal power technology and has been verified through commercialization in the past 30 years.The parabolic trough collector is the core part of the solar parabolic trough power generation.A test platform is established for evaluating the thermal performance of the parabolic trough collector.The testing results indicate that the parabolic trough collector has a high thermal performance with the overall conversion ratio from solar radiation to high temperature heat exceeding 70%;some solar collector tubes are aged rapidly by the 320 ℃ thermal oil,which reduces the overall thermal performance of the parabolic trough collector.
