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 steam extractions to first three of which three high-pressure regenerative heaters are connected, and two last four of which four low-pressure regenerative heaters are connected placed in circuit of regenerative heating of main condensate and feed water. Said thermal power station has 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, additional feed water vacuum deaerator with influent, deaerated water and heating agent pipelines. Heating agent pipeline of additional feed water vacuum deaerator is connected to steam line of turbine fifth steam extraction.

EFFECT: improved reliability and economy of thermal power station owing to stable provision of vacuum deaerator of additional feed water with low-potential heating agent of technologically required parameters.
