Temperature Field Numerical Simulation Analysis of 1000MW Ultra Supercritical Boiler’s Starting Water Separator

Abstract:

Aiming at the structural feature of starting water separator, a 3-D finite element model of temperature field is proposed. The starting water separator of a Ultra Supercritical Boiler(USB) has been numerically simulated by using of finite element soft ware Ansys. The boundary condition of the separator is determined. All of the working conditions are simulated. The results have the same distribution laws with the monitoring data of power plant. The maximum temperature difference between out wall and inner wall occurs in the temperature-rise period during the cold start-up, but the value between top wall and bottom wall is very lower. The simulation results can not only provide a basis for the thermal stress analysis and the life loss calculation but also provide rationalization proposal for the plant safe operation.
