METHOD OF OPERATION OF THERMAL POWER STATION Russian patent published in 2006 - IPC F01K17/02 

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 is directed for heating system water in lower and upper system heaters, respectively. System water is heated after system heaters in steam-water system heater for air heaters of steam generator by delivering heating medium. Used as such heating medium is steam from fifth extraction of type T turbine with heating steam extractions.

EFFECT: improved economy and reliability of thermal power station owing to use of stable low grade heat source as heating medium in steam-water heater of system water for air heaters of steam generator.
