摘　　要：碳达峰与碳中和愿景下,300 MW亚临界汽轮机面临节能降耗综合改造压力。文章提出了3种通流改造方案,主再热参数不变的常规通流改造、主再热升参至超临界温度的通流改造、主再热升参至超超临界温度的通流改造方案,对比了3种方案改造收益,为同类型机组改造提供参考意义。With the hope of peak carbon emissions and carbon neutrality,300 MW suberitical steam turbine faces the presure ofupgrading for energy-saving and consumption reducing.This paper proposes three through_ow upgrade schemes for the steamturbine,including scheme of main and reheat steam parameter unchanged,scheme of main and reheat steam temperature rising tosupercritical temperature and scheme of main and reheat steam temperature rising to ulra-supereriical temperature."The benelits ofthree schemes are compared in this paper.lt provides a reference for the transformation of the same type of steam turbine.
