Sažetak
All the more extensive usage of steam turbines for ensuring variable part of electric load is characterised by requirements for high manoeuvrability of operation (rapid starting, stopping and change of power). In these conditions both at elaborating new designs of steam turbines and in their operation, the additional attention is dedicated to thermally most loaded thick-walled parts, as steam turbine casings, stop and governing valves of high pressure, in which the intense space and time dependent temperature gradients cause high non-stationary thermal stresses. In both cases the different problems are solved which demand knowledge about non-stationary thermal stresses in steam turbine thick-walled parts. In the present time non-stationary thermal stresses (clearly as well as the state of total stresses) are efficiently calculated by modelling by means of the user software programs (of software packages), which are based on numerical methods. As example the paper presents the procedure and the results of non-stationary thermal stresses modelling in steam turbine casing by means of the user software package.
