Abstract: The carbon emissions of the thermal power industry account for 40% of the total emissions. Vigorously carrying out
steam turbine flow passage transformation in thermal power plants is an effective way to help achieve carbon peak and carbon
neutrality, and it is also the implementation plan requirements issued by the National Development and Reform Commission.
Therefore, this paper introduced the technical scheme of flow passage renovation in A Power Plant, and summarized the advanced
technology used in the renovation. After transforming, under the working condition of THA, the unit heat consumption was reduced
about 260.1 kJ/(kW·h), standard coal was saved about 2.34 ×10⁴ t, CO₂ emission was reduced about 5.86 ×10⁴ t, SO₂ emission
was reduced by 199 t, NO_x emission was reduced by 176 t each year. Energy saving and carbon reduction effect was obvious, and
environmental protection effect was also very obvious.

Key words: supercritical; flow passage renovation; steam turbine; energy saving effect
