Abstract
Promoting the development of concentrating solar power (CSP) is critical to achieve carbon peaking and carbon neutrality. Molten salt tanks are important thermal storage components in CSP systems. In this study, the cold and hot tanks of a 100 MW CSP plant in China were used as modeling prototypes. The materials and geometric models were determined based on related specifications and engineering experience. Mechanical characteristics of the tanks under steady condition, including the deformation, stress distribution, and stress concentration, were simulated and calculated. Furthermore, the strength of the tank walls was evaluated. The findings can be used as a reference for designing the storage tank and reducing the risk during operations.
