Abstract

This work aimed at developing a glass to metal seal for the tubular receiver in parabolic trough solar power plant. A novel self developed glass (GD480S) was developed and the sealing structure was optimized by the examination of air tightness, tensile strength, and thermal shock resistance. The results showed that the self developed glass presented a compliant coefficient of thermal expansion to 4J29 Kovar alloy. An optimized performance was realized using bilateral structure with a sealing length of 35 mm. T he assembly of the se al using self developed glass and designed structure can meet the requirement of industrial tubular solar receiver..
