FIELD: power engineering.
SUBSTANCE: method for condensation of spent steam of a turbine includes supply of a part of spent steam into a primary condenser, cooled by return water, in which it is condensed, after which the primary condensate along the condensate line with a working pump is supplied to the nozzles of a multi-stage ejector, besides, the other part of the spent steam is supplied to the receiving chamber of the first stage of the multi-stage ejector, besides, the steam-liquid mixture downstream the multi-stage ejector is supplied to the secondary condenser cooled with air, in which all steam is condensed, and non-condensed gases are removed. Also the device is proposed for realisation of the method.
EFFECT: invention makes it possible to increase efficiency of condensation of spent steam of a turbine.
