Research on Circumferential Thermal Stress Field of Coke Drum Using ANSYS Ruitao Zhua School of Civil Engineering, Xi'an University of Architecture and Technology, Xi’an 710055, China azzrrtt30@sina.com Keywords: coke drum, circumferential thermal stress field, ANSYS, indirect coupling method Abstract.
In addition, there are not accurate measuring methods .Therefore, it is of vital importance in theory and engineering practice to further understand the effect of thermal stress .The circumferential thermal stress field of coke drum is extraordinarily complicated .It is caused for two reasons: one is the different instantaneous temperature along the shell should arouse greater stress which can generate thermal ratcheting and thermal fatigue the other is the thickness of residual coke caused by unsteady flow of gas or liquid is different , which can generate the circumferential temperature difference in the shell of coke drum.
