Abstract: The invention relates to a steam and gas turbine device comprising a gas turbine unit (A) and a steam turbine unit (B), wherein the gas turbine unit (A) is partly composed of at least the following: a gas compressor (1) positioned on a compressor axle (4), a combustion chamber (2) and a gas turbine (3) positioned on a gas turbine axle (5); and wherein the steam turbine unit (B) is partly composed of the following: a closed steam line (6) in which at least the following are accommodated: a pump (7); a steam converter (8; 50), which, in operation, is in heat-exchanging contact with the gases (3b) coming from the gas turbine (3); a steam turbine (9) positioned on a steam turbine axle (10); as well as a condenser (11).

Abstract: Steam and gas turbine installation comprising a gas turbine unit (A) and a steam turbine unit (B), in which the gas turbine unit (A) is built up in part of at least: a gas compressor (1) mounted on a compressor shaft, a combustion chamber (2) and a gas turbine (3) mounted on a gas turbine shaft; and in which steam turbine unit (B) is built up in part of: a closed steam line, at least comprising: a pump (7), a steam generator (8), which is in heat-exchanging contact with combustion gases from the gas turbine during operation, a steam turbine (9) mounted on a steam turbine shaft as well as a condenser (11). The steam and gas turbine installation according to the invention is characterized in that the steam turbine (9) drives the gas compressor (1) of the gas turbine unit during operation.
