FIELD: power industry.
SUBSTANCE: in heat exchanger installed as to heating medium into the network installation before network heaters of extraction turbine, and as to heated medium - into the feed path of the turbine having condenser, after the condensate pump there performed is re-distribution heat energy from the network installation of extraction turbine to regenerative diagram of the turbine having the condenser.
EFFECT: increasing economy, reliability and manoeuvrability of the plant owing to increasing the economy of extraction turbines, at increase of the fraction of eclectic power generated on the basis of heat consumption and smoothing of temperature of return system water, generation of additional electric power on the turbine having the condenser.
