METHOD OD OPERATION OF THERMAL POWER STATION Russian patent published in 2006 - IPC F01K13/00 

FIELD: heat power engineering.

SUBSTANCE: according to proposed method, steam from first three extractions of extraction turbine is delivered to high-pressure regenerative heaters, steam from last four extractions is delivered to low-pressure regenerative heaters in which main condensate after turbine condenser and feed water are heated successively, and steam from seventh and sixth extractions of turbine is delivered for heating system water, respectively, in lower and upper heating system heaters, and influent water and heating agent are delivered into vacuum deaerator of additional feed water. Deaerated additional feed water is used as heating agent which is heated before delivery into vacuum deaerator by steam fifth extraction of turbine.

EFFECT: improved reliability and economy of thermal power station owing to provision of stable and highly economical heating of heating agent before vacuum deaerator of additional feed water to technologically required temperature at minimum capital outlays for reconstruction of thermal power station.
