Abstract: The parameters of existing 1000MW Ultra-supercritical units were analyzed combining with the development tendency of the same units domestic and abroad. The recommended parameters for the project of Boxing Power Plant are as follow: 26.25MP and 600℃/600℃ for the ultra-supercritical turbine inlet, 27.56MPa and 605℃/603℃ for the related boiler. The evaporation capacity of boiler usually matches the working condition of VWO (valve widely open) of turbine. By analysis for the parameters of the pipe material, P91, P122 and T91 are selected for the main piping material for this 1000MW unit.
