FIELD: heat power engineering. ^ SUBSTANCE: according to proposed method, steam from first three extractions of type T extraction turbine is directed to high-pressure regenerative heaters, and from last four extraction, to low-pressure generative heaters in which main condensate after turbine condenser and feed water are heated successively. Steam from seventh and sixth extractions of type T turbine is directed for heating system water in lower and upper system heaters, respectively. Source water is heated in steam-water heater of source additional feed water before delivery to desalination plant by delivering heating medium, steam from fifth extraction of type T turbine being used as heating medium. ^ EFFECT: improved economy and reliability of thermal power station owing to use of source additional feed water from stable source of low-grade heat as heating medium in steam-water heater of source additional feed water. ^ 1 dwg |
