Abstract
Parabolic trough solar system is one of the most promising environmentally preferred advanced power generation technologies. The evacuated tubular solar couector is the key component of a parabolic trough solar power plant, and the the heat performance of the collector plays a prominent role on the gross efficiency of the entire system. A new high temperature evacuated tubular solar collector was designed and produced by Southeast University and Sanle Electronic Group. A thermal property test was accomplished by using an electric resistance heater inside the collector to reach the desired absorber temperatures in steady-state equilibrium. Experimental results show that this kind of new collector has got long term stability in high working temperature(350°C), and thermal properties are close to Solel UVAC-3 throughout whole temperature range, which is a perfect choice for China's future parabolic trough solar power plant. The specific setup of the entire experimental platform, intentions of each device, as well as the detailed procedures and analysis of the experiment are introduced.
