| Abstract: | Numerical simulations were respectively conducted of two waste heat boilers with and without insulting layers on the outside shells using ANSYS software,the distribution of the temperature fields of the boilers was analyzed,the thermal stress generated by temperature gradient was calculated.The temperatures and thermal stresses of the two boilers were compared,it was concluded that the insulating layers could reduce the temperature of the outside wall surface and the thermal stress. |
