METHOD OF OPERATION OF GAS-STEAM THERMOELECTRIC PLANT Russian patent published in 2006 - IPC F01K21/04 

FIELD: power engineering.

SUBSTANCE: according to proposed method of operation of gas-steam thermoelectric plant, atmospheric air is compressed in compressor and fuel is combustion in said air, useful work of high-pressure turbine is used for compressing the air, useful work of low-pressure turbine is used to drive electric generator and generate power. Heat of waste steam-gas mixture is recovered for generation of superheated steam. Superheated steam is expanded in counterpressure steam turbine whose useful work is used for generation of power, and "ecological" steam expanded in counterpressure steam turbine is fed to combustion products coming out of high-pressure gas turbine, and "power generating: steam is fed into fuel burning zone of additional combustion chamber.

EFFECT: increased power and improved economy of gas-steam thermoelectric plant, possibility of use of existing gas and steam turbines with standard parameters of steam for creating said thermoelectric plant.
