THERMAL POWER STATION Russian patent published in 2006 - IPC F01K13/00 

FIELD: heat power engineering.

SUBSTANCE: according to invention, proposed thermal power station contains extraction turbine with seven steam extractions to first three of which three high-pressure regenerative heaters are connected and to last four, four low-pressure regenerative heaters are connected being placed in regenerative heating system of main condensate and feed water, condenser, upper and lower heating system heaters placed in heating system pipeline and connected by heating medium line, respectively, to sixth and seventh steam extractions, vacuum deaerator of additional feed water with pipelines of influent, deaerator water and heating agent. Steam-water heat exchanger connected by heating medium line to fifth steam extraction of turbine is placed in heating agent pipeline of additional feed water vacuum deaerator.

EFFECT: improved reliability and economy of thermal power station owing to 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.
