FIELD: heat power engineering; thermal power stations. ^ SUBSTANCE: invention is designed for heating system water and it can be used in thermal power stations. Proposed thermal power station contains steam turbine with heating steam extractions and condenser to which pressure and drain circulating water pipelines are connected, lower and upper heating system heaters connected by heat medium end between feed and return heating system pipelines and connected by heating medium end to heating extractions, influent make-up water pipeline connected to return heating system pipeline and heat pumping unit with two-stage evaporator and condenser. First stage of evaporator is connected to drain circulating water pipeline, second stage of evaporator is connected to return heating system pipeline before lower heating system heater, and first stage of condenser of heat pumping unit connected with first stage of evaporator is connected by heating medium end to pipeline of influent make-up water, second stage of condenser connected with second stage of evaporator is connected to feed heating system pipeline between lower and upper heating system heaters. ^ EFFECT: improved economy of thermal power station. ^ 1 dwg |
