| Abstract: | Aimed at header of steam collecting channel, a 3D model was built by using of software of UG, and the convection coefficients were got by ANSYS. The transient thermal-structural analysis was carried out on the model to get the stress values and distribution of the header of steam collecting channel during emergency starting. The paper discussed about the causes for the crackes, forecasted where they most likely to happen, and the trends of spreading. |
