METHOD OF OPERATION OF THERMAL POWER PLANT Russian patent published in 2013 - IPC F01K17/02 

FIELD: power engineering.

SUBSTANCE: steam is generated in a boiler and sent into a turbine, then steam is condensed in a condenser, the main condensate of the turbine is removed from the condenser along the pipeline of the main condensate with a condensate pump and sent into regenerative low pressure heaters. The steam and air mixture is removed along a pipeline of steam and air mixture removal into a cooler of the steam and air mixture, and then with a steam jet ejector it is removed into a steam cooler, where it is cooled with initial demineralised water, which is then along the pipeline of the initial demineralised water is removed for deaeration into a vacuum deaerator of make-up feedwater. Air released from the steam and air mixture from the steam cooler is removed into atmosphere. The condensate of spent steam of the steam jet ejector from the cooler of steam and steam released from the steam and air mixture from the cooler of the steam and air mixture is sent along condensate pipelines into the vacuum dearator of the make-up feedwater. The make-up feedwater is deaerated in the vacuum deaerator of the make-up feedwater and sent with a pump along the pipeline of the make-up feedwater into the main condensate pipeline, for instance, downstream the condensate pump.

EFFECT: invention makes it possible to increase efficiency of operation of a thermal power plant.
