A parabolic trough solar receiver is the key component in the parabolic trough solar system. The annulus between the absorber and glass envelope is evacuated to protect the solar selective coating and decrease the heat loss of entire receiver. However, at any existing operational solar plants, the vacuum condition in annulus may be compromised by glass breakage, seals and bellows broken, hydrogen...
The vacuum solar receiver is the key component of a parabolic trough solar plant, which plays a prominent role in the gross system efficiency. Recently, China’s first high temperature vacuum receiver, Sanle-3 HCE, has been developed and produced by Southeast University and Sanle Electronic Group. Before being utilized in China’s first parabolic trough solar plant, accurately estimating the thermal...
