FIELD: engines and pumps.
SUBSTANCE: invention refers to warming method of steam turbine including intermediate pressure partial turbine and/or low pressure partial turbine. Intermediate pressure turbine includes the supporting device on its outlet side; at that, during the start-up process, the steam flowing through intermediate pressure partial turbine is supported at the outlet by means of supporting device so that steam pressure in intermediate pressure partial turbine increases. The steam leaving intermediate pressure partial turbine is supported, due to which steam pressure and temperature increases. Heat transfer of steam to thick-wall structural elements located in intermediate pressure partial turbine, as well as to the shaft of intermediate pressure partial turbine increases.
EFFECT: invention allows reducing the start-up time of steam turbine.
