FIELD: internal combustion engines.
SUBSTANCE: exhaust gas recuperation system of at least one gas turbine engine includes turbine, compressor, first and second heat exchangers, fan. Turbine is installed with possibility of rotation around recuperation shaft and is arranged with the possibility of selection of at least part of exhaust gases, called extracted gases, and with possibility of expansion of extracted gases to produce gases expanded to pressure below atmospheric pressure. First heat exchanger is configured to cool the expanded gases by means of a cold source to produce cooled gases. Compressor is arranged to rotate about recovery shaft and is configured to compress said cooled gases to atmospheric pressure. Fan is configured to provide cold source to first heat exchanger and is rotated by recuperation shaft. Second heat exchanger is configured to provide preliminary cooling of expanded gases before they enter the first heat exchanger.
EFFECT: invention is aimed at increasing the efficiency.
