| Abstract: | Stress calculations are necessary to determine the feasibility and profitability of a heat storage tank’s construction. The article presented normative methods of stress calculations for a heat storage tank. Results were verified by finite element analysis. These stress calculations enabled us to determine wall and weld thickness. The calculations were made on the example of a tank with a nominal pressure of 10 bar. The work undertook an extensive analysis of the stresses occurring in a pressure tank, described the finite element method and showed examples of ways in which it could be used. During stress analysis, three types of materials were compared: carbon steel St0 (S185), stainless steel (304) and boiler steel (P 265 GH). A brief overview of types of thermal energy storages was also provided. |
