FIELD: heat-and-power engineering, may be used for refinement and passivation of steam turbines' setting or for the purpose of their temporary closing-down or increasing effectiveness of exploiting.
SUBSTANCE: refinement and passivation is carried out by processing of the surface of the setting by oxygen-steam mixture under definite temperature mode of operation. The setting is processed at revolving rotor at that the steam temperature at turbine's exit is below 180°C. Processing is made in series - at free-running during 2-6 hours at the temperature of 70-300°C at the turbine's exit, then under load within the limits of 10-40% of nominal during 7-10 hours at the temperature within the limits of 400-540°C at turbine's entry.
EFFECT: provides possibility for refinement and passivation of steam turbine's setting by the most effective and environmentally appropriate mode.
