Practical methods of calculating the autoclaves’ thermal stresses at building industry

The study is devoted to elaboration of a simplified method for calculation of stresses arising in the autoclaves' casing in the case of nonlinear distribution of temperature field on its cross section height. The piece-nonlinear function is applied to the temperature field of autoclaves as maximally corresponding to experimental results. On the basis of flat sections hypothesis an expression for temperature stresses is obtained. The analysis of their distribution by the autoclave casing height is made. The control test confirmed a sufficient efficiency of the offered method for engineering needs. Keywords: autoclave, temperature difference, condensate level, thermal stresses.
