THERMAL POWER STATION Russian patent published in 2006 - IPC F01D17/02 

FIELD: heat power engineering; thermal power stations.

SUBSTANCE: proposed invention increases economy and reliability of thermal power station owing to stable and high-economy heating of heat-carrying agent before vacuum deaerator of make-up water of heating system to technologically required temperature at minimum capital outlays for reconstruction of thermal power station. For this purpose, proposed thermal power station contains steam turbine with seven steam extractions, to first three of which three regenerative high pressure 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 connected to heating system water pipeline and connected by heating medium ends to sixth and seventh steam extractions, respectively, vacuum deaerator of make-up water of heating system with pipelines of influent, deaerated water and heat-carrying agent. Steam-water heat exchanger is placed in heat-carrying agent pipeline of vacuum deaerator of make-up water of heating system being connected by heating medium end to fifth steam extraction of turbine.

EFFECT: improved economy and reliability of thermal power station.
