METHOD OF OPERATION OF THERMAL POWER STATION Russian patent published in 2003 - IPC

Abstract RU 2214518 C2

FIELD: heat power engineering. SUBSTANCE: according to proposed method, main condensate of turbine is heated in low-pressure regenerative heaters and is delivered into high-pressure deaerator, additional feed water is deaerated in vacuum deaerator into which source water and heating agent are delivered, source water is heated in water-to-water, steam from lower and upper heating extractions of turbine are delivered, respectively, into lower and upper line heaters to be used as heating medium. Condensate from lower line heater is used as heating medium in water-to-water heater of source water, and steam from upper heating extraction is used as heating agent in vacuum deaerator. Cooled condensate from lower line heater is delivered into turbine main condensate pipe line after water-to-water heater before low-pressure heater first in direction of main condensate flow. Deaerated additional feed water is delivered into turbine main condensate pipeline after low-pressure heater first in direction of turbine main condensate flow. EFFECT: increased economy, improved reliability of thermal power station. 3 cl, 1 dwg
