The Impact and analysis of nuclear power plant’s steam extraction and heating modification on the turbine

Abstract

Abstract A certain nuclear power unit uses the circulating water heated by the steam extraction from the high-pressure cylinder exhaust pipe of the steam turbine through modification, and the pressurized heating circulating water is supplied to the outside of the plant. As it is the first large-scale model of steam extraction heating in domestic nuclear power, the heating will have a certain impact on the steam turbine. Therefore, it is necessary to analyze the impact of large-scale steam extraction on the steam turbine and propose corresponding countermeasures to provide relevant references for subsequent nuclear power extraction and heating modification.
