The Right

The security and stability of the steam turbine equipments are of great importance for thermal power plants. The diaphragm of steam turbine is usually tested as lack of stiffness due to creep deformation in the practical operation. In this paper, a creep life assessment of the diaphragm of a practical steam turbine was presented. The finite element model of the diaphragm was construed, and its accuracy was verified via a defection test. The classic Norton creep law was applied to the calculation process and its creep parameters were determined via iteration to obtain an appropriate value which would make the calculated deformation data equal to the practical experimental data. The creep life of the diaphragm was obtained based on the appropriate finite element model and the right creep parameters. The result shows that the method is an effect way in the engineering field to evaluate the creep life of components of steam turbine and gas turbine’s equipment in the situation that the material property is unknown.
