Beschreibung
Zusammenfassung:	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 steam from last four extractions, to low-pressure regenerative heaters in which main condensate after turbine condenser and feed water are heated successively. Steam from seventh and sixth extractions of type T turbine are directed for heating system water in lower and upper system heaters, respectively. Additional feed water after vacuum deaerator is heated in steam-water heat exchanger before delivering into higher pressure deaerator. Steam from fifth extraction of type T-turbine is used as heating medium in said steam-water heat exchanger. ^ EFFECT: improved reliability and economy of thermal power station owing to provision of technologically required heating of additional feed water after vacuum deaerator delivered into higher pressure deaerator using stable low-grade heat source. ^ 1 dwg
