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

FIELD: heat power engineering. SUBSTANCE: according to proposed method main condensate of turbine is heated in regenerative low-pressure heaters and is delivered into high-pressure deaerator. Additional feed water is deaerator in vacuum deaerator into which source water and heating agent are delivered, and source water is heated and water-to-water heater, and steam from lower and upper turbine heating extractions, respectively, is delivered into lower and upper line heaters. Condensate from lower line heater is used as heating medium in water-to-water heater of source water. Cooled condensate of lower line heater is delivered after water-to-water heater into turbine main condensate pipeline before low-pressure heater first in direction of turbine main condensate flow. Deaerator 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
