Abstract |
|
In the power plant industry, plant boilers have regulated steam temperature so that the boiler and turbine-generator can operate properly and efficiently. A replaceable liner is installed for protection against erosion and thermal shocking of the desuperheater pressure shell. The proposed methodology and concepts are new and unique, and demonstrate the applicability to general transient non-linear/linear thermal analysis situations. Characteristic features and pertinent details of the approach are described for non-linear/linear transient thermal problems, where in non-linearity’s due temperature dependence of thermo physical properties and/or general non-linear boundary conditions to include radiation, effects due to phase change, etc., are considered. |
