OPERATING METHOD OF COMBINED CYCLE PLANT Russian patent published in 2010 - IPC F01K21/04 

FIELD: power industry.

SUBSTANCE: operating method of combined cycle plant consists in the fact that ambient air is compressed with compressor and supplied to combustion zone of combustion chamber to which there also supplied is fuel; in that chamber the fuel is mixed with compressed air and the obtained combustible mixture is burnt; combustion products obtained in the form of gas mixture are mixed with water vapour so that working steam-gaseous body is obtained at the chamber outlet as steam-gas mixture, which is supplied to turbine in which the flow energy of steam-gas mixture is converted to mechanical energy of turbine rotor rotation, by means of which rotor of compressor and rotor of electric generator are brought into rotation for generation with the latter of electric energy; at that, plant is equipped with additional compressor, heat exchanger, condenser, feed pump, separation unit of non-condensed gaseous combustion products and reserve capacity.

EFFECT: increasing useful capacity of turbine and reducing combustion products emissions to atmosphere with the appropriate increase of environmental safe operation of combined cycle plant.
