Abstract
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.
