METHOD OF OPERATION OF THERMAL POWER STATION Russian patent published in 2006 - IPC F01D17/02 

FIELD: heat power engineering.

SUBSTANCE: proposed invention increases economy and improves reliability of thermal power station owing to stable and high economy heating of heat-carrying agent before vacuum deaerator of make-up water of heating system to technologically required temperature at minimum capital outlays for reconstruction of thermal power station. To obtain this result, when operating thermal power station, steam from three steam extractions of extraction turbine is directed to high pressure regenerative heaters, and from last four extractions, to low-pressure regenerative heaters in which main condensate after turbine condenser and feed water are successively heated. Steam from seventh and sixth turbine extractions is directed for heating system water, respectively, in lower and upper heating system heaters. Influent water and heat-carrying agent are directed into vacuum deaerator of make-up water of heating system, make-up water or heating system water being used as heat-carrying agent. Water used as heat-carrying agent of vacuum deaerator of make-up water of heating system is heated by steam of fifth extraction of turbine before delivery into vacuum deaerator.

EFFECT: improved economy and reliability of thermal power station.
