Analysis of the Superheated Steam Cycle of a PWR Secondary System

摘要

The impacts of variations of turbine exhaust steam wetness, live steam parame- ters, and the turbine sectional pressure ratio on the thermodynamic efficiency of the saturated steam cycle in a PWR secondary system are analyzed. The effects of live steam parameters and turbine sectional pressure ratio on the thermodynamic efficiency and the turbine exhaust steam wetness for the superheated steam cycle are also investigated. The optimum ranges of operating parameters are proposed based on the comparison of the performance of the superheated steam cycle with that of the saturated steam cycle.
