A turbomachine, in particular a gas turbine, is in the traditional manner provided with air cooling of the components that are subject to a high thermal stress. The cooling system (21, 31, 41) is provided with elements through which another medium (25, 35, 45), for example water or steam, can be add
A turbomachine, in particular a gas turbine, is in the traditional manner provided with air cooling of the components that are subject to a high thermal stress. The cooling system (21, 31, 41) is provided with elements through which another medium (25, 35, 45), for example water or steam, can be added to the cooling system during peak demand. This medium displaces cooling air (26, 36, 46) from the cooling system, the air being then available additionally in a heat generator (2, 4). This means that more fuel (12, 13) can be added without increasing the hot gas temperature (T.sub.1, T.sub.3) at the turbine inlet (301, 501), and the power is increased. The quantity of the medium added to the cooling system is controlled by control elements (24, 34, 44) as a function of a control deviation (P.sub.set -P.sub.act) of the power.

[ What is claimed is:] [1.] A turbomachine comprising:A at least one heat generator having a fuel inlet, a compressed gas inlet, and a compressed hot gas outlet, wherein when fuel and compressed gas are combusted in the at least one heat generator, compressed hot gas flows out the compressed gas outlet in a hot gas stream;at least one turbine having an inlet in fluid communication with the heat generator compressed gas outlet, wherein when compressed hot gas is generated in the at least one heat generator, the compressed hot gas is expanded in the at least one turbine to produce mechanical power;a cooling system supplying at least one partial stream of an at least partially compressed gas to the hot gas stream, the at least one partial stream flowing to portions of the at least one heat generator, the at least one turbine, or both, that are subject to high thermal stress, prior to being added to the hot gas stream, the at least one partial stream flowing through the cooling system not being used for combustion;means for adding at least one second medium to the cooling system, the second medium displacing gas from the cooling system, the displaced gas therefore being available directly for thermal power conversion; andmeans for regulating the flow rate of the second medium as a function of a control deviation of the power.
