Steam and Gas Turbine Device

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) and wherein, in operation, the steam turbine (9) drives the gas compressor (1) of the gas turbine unit (A), wherein the gas turbine unit (A) furthermore comprises at least one heat exchanger (20) which brings the combustible flue gases coming from the combustion chamber (2) into heat-exchanging contact with the gases coming from the gas compressor (1) and wherein the gas turbine unit (A) comprises a blow-off valve (21) which is arranged upstream of the gas turbine (3) for blowing off the gases coming from the gas compressor (1).
