FIELD: engines and pumps.
SUBSTANCE: steam turbine plant comprises steam generator, steam turbine connected to it by means of live steam pipeline with cylinders of high and medium pressure, at that the latter have bleeds, and also rotors and stators arranged with cavities for cooling of their high-temperature sections, at that in lines of cooling steam supply to cavities of high and medium pressure ejectors are installed, which are connected by working steam inlet of ejectors to live steam pipeline, and by suction of ejectors - to turbine bleed pipelines. Suggested technical solution makes it possible to produce steam with required parametres for cooling of thermally stressed units of turbine in all operational modes without permanent additional control of its flow rate.
EFFECT: simplified design of cooling system, increased reliability, reduced metal intensity and cost.
