GAS-TURBINE POWER PLANT WITH EXHAUST GAS RECIRCULATION Russian patent published in 2016 - IPC F02C3/34 

FIELD: engines and pumps.

SUBSTANCE: described is method of gas-turbine power plant, where fresh air (2) is supplied to input (3) of compressor and accelerated in inlet (3) of compressor, and re-circulated substream (21) of exhaust gases is supplied to inlet (3) of compressor, in which fresh air (2) is accelerated to such degree that difference between total pressure and static pressure of fresh air (2) is greater than or equal to difference of pressures required for suction of end of mass flow of re-circulated first subflow (21) of exhaust gases in input (3) of compressor. Also described is gas-turbine power plant with gas turbine (6), compressor's inlet of which is divided into two sectors (3′, 3″), to which adjacent is compressor path (1), fresh air supply device is connected to first sector (3′), and recycling line to circulate first subflow (21) of exhaust gases is connected to second sector (3″), and second sector (3″) fits so close to compressor (1), that during operation of gas turbine (6) of static pressure at second sector (3″) is so low difference between total pressure and static pressure exceeds or equals difference of pressures required for suction of end of mass flow of re-circulated first subflow (21) of exhaust gases in input (3) of compressor.

EFFECT: reliable operation of gas turbine engine with exhaust gas recirculation without using fans to overcome pressure losses in recirculation lines.
