FIELD: power engineering; thermal power plants. SUBSTANCE: method involves steam energy conversion by supplying reheat steam to working chambers and discharging dead steam from them. Turbine rotor spider has holes providing alternate communication between chambers and reheat-steam and water delivery passages. After chambers are filled with reheat steam, water is injected into them in the amount sufficient to ensure water hammer within chambers upon its evaporation. EFFECT: enhanced efficiency, simplified design, facilitated maintenance of turbine. 1
