GAS TURBINE PLANT WITH SUPERCRITICAL EXPANSION OF WORKING GAS Russian patent published in 2022 - IPC F02C3/34 

FIELD: power engineering.

SUBSTANCE: invention relates to the field of power engineering and for the design of gas turbine plants used in the electric power industry. Gas turbine plant with supercritical expansion of the working gas, containing a compressor, a regenerator, a combustion chamber, a gas turbine, an electric generator, while the working gas from the combustion chamber is directed to the flow part of the duct once-through gas cooler, where it expands to supersonic speed, while the flow part of the duct once-through gas cooler is docked to the flow part of the turbine, and the duct once-through gas cooler itself is located around the axis of the combustion chamber, and compressed air from the compressor is supplied into the annulus of the duct once-through gas cooler, and from it into the combustion chamber, while the turbine, electric generator, compressor are kinematically connected to each other through a gearbox.

EFFECT: invention makes it possible to increase the efficiency of the gas turbine plant and reduce the dimensions and weight of the plant.
