| Abstract: | Metal temperature profiles of the LP inner-case of 125 MW steam turbine are calculated. Experimental correlation is used to predict convective heat transfer coefficient between metal surface and steam in LP casing. 2D finite element scheme with axial symmetry is used to predict metal temperature profiles. With application of the practical operation curve during turbine start-up and stop processes, instantaneous temperature field is obtained and character of temperature in turbine LP inner-case is presented. |
| Keywords: | LP inner casing temperature field finite element method turbine |
