Patent ID: 8661780

Claim:
A gas turbine plant with exhaust gas recirculation, comprising at least one main gas turbine ( 11 , 12 , 13 , 16 ) having at least one main compressor and at least one main turbine which drives a main generator or other machine, and at least one combustion chamber, an outlet of which is connected to an inlet of the at least one main turbine of the at least one main gas turbine, has a fuel feed, and via a high-pressure side of a recuperator obtains combustion air from an outlet of the at least one main compressor of the at least one main gas turbine, wherein an outlet of the at least one main turbine and an inlet of the at least one main compressor of the at least one main gas turbine are connected via a low-pressure side of the recuperator and a cooler for exhaust gas recirculation, and wherein, on the low-pressure side of the recuperator, a charging unit with a compressor and a turbine is arranged, the charging unit draws in air via an air intake and by an outlet of the compressor is connected to an outlet of the low-pressure side of the recuperator and by an inlet of the turbine is connected to a surplus-gas extraction line on the low-pressure side of the recuperator, and wherein a CO 2 separator separates CO 2 from exhaust gas from the charging turbine and wherein for cooling fluid supply of the at least one main turbine and other thermally loaded parts of the at least one main gas turbine, one or more partial flows are branched off from the recuperator and directed to the places to be cooled via at least one supply line.
