The equipment for increase of output and improvement of efficiency of a gas turbine includes a primary compressor (101) with an impeller for input medium compressing, a combustion chamber (102) for heating the compressed input media and a primary gas turbine (103) with an impeller driven by combustion gases from the combustion chamber (102) and power-connected with the impeller of the primary compressor (101), whereas for heating of the compressed input medium the combustion chamber (102} is provided with an inlet of a fuel mixture from a secondary system (1) for preparation of the fuel mixture by mixing of the fuel with an oxidiser, whereas according to the invention the secondary system (1) includes a secondary gas generator (4) with an inlet (41) of the compressed fuel, with an inlet (42) of the compressed oxidizer and with an outlet (43) of the partly combusted fuel mixture connected with an inlet of a secondary gas turbine (3), whereas the outlet of the secondary gas turbine (3) is connected with the combustion chamber (.102) of the primary gas turbine (103) and the shaft (31) of the secondary gas turbine (3) is power-connected with an equipment (2, 8, 22, 23, 24) for energy consumption. With advantage the shaft (31) of the secondary gas turbine (3) is power-connected with a shaft (21) of an upstream primary compressor (2) for compression of the input medium, the outlet of which is connected with inlet of the primary compressor (101) or with the shaft (221) of the secondary compressor (22) for compressing of the oxidiser, while the inlet of the secondary compressor (22) is connected with the outlet of the primary compressor (101) and the outlet of the secondary compressor (22) is connected with the inlet (42) of compressed oxidiser into the secondary gas generator (4).
