Experimental analysis of residual gas of vacuum annulus in parabolic trough solar receivers

According to the operation statistics of SEGS power station, the average failure rate of early parabolic trough solar receivers is high to 4.1%, of which 29% is caused by vacuum failure. The vacuum characteristic of parabolic trough solar receiver is an important factor affecting the operation effic...
