abstract:
In order to analyze the packed-bed tank failure and molten salt leakage problems induced by the high temperature creep and alternative stress in the solar power station, a coupled thermal-mechanical method for analyzing the creep and mechanical performances of the commercial tank with 347H material was developed by taking into account the real structure and stress loads, and the corresponding dynamic characteristics in different charging-discharging time were further numerically studied. The results show that the temperature change rate of the tank wall is obviously lower than that of the packed-bed region, and the creep phenomenon occurs at first on the wallboards 1-4 (4.2
