摘要： A gas turbine group is provided with at least one cooling apparatus for cooling the working medium before and/or during the compression. The cooling power of the cooling apparatus can be adjusted by suitable means. A controller controls the cooling power of the cooling apparatus as a function of a control deviation in the useful power of the gas turbine group. The cooling controller interacts with other controllers of the gas turbine group in such a way that the gas turbine group is itself always operated at least close to its full load operating state. In this context, it is preferable for the inlet guide vane row of the compressor to be maximally open, and for the hot-gas temperature on entry into the turbines to be controlled so that it is constantly at an upper limit value.

摘要： A method of operating a gas-turbine power plant is described, having a gas-turbine plant (1) in which an oxygen-containing gas is drawn in, compressed and fired and, after passing through a turbine stage, is fed as discharging hot gas (8) to a waste heat boiler (4), from which the cooled exhaust gas (9) is fed to an outlet (10) and then to the free atmosphere. The invention is characterized in that a specific reduction in the flow velocity with which the exhaust gas (9) flows through the outlet (10) is effected in the region of the latter, with a simultaneous pressure increase downstream in the outlet (10), and in that the pressure conditions occurring inside the outlet (10) are transmitted free of losses between the gas turbine (1) and the outlet (10) via a gas-tight flow path of the hot and exhaust gases (8; 9).

摘要： 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.
摘要翻译：涡轮机械，特别是燃气轮机，采用传统的方式，对经受高热应力的部件进行空气冷却。冷却系统（21,31,41）设置有元件，通过该元件可以在峰值需求期间将另一介质（25,35,45）例如水或蒸汽添加到冷却系统中。该介质从冷却系统中移出冷却空气（26,36,46），然后另外在发热体（2,4）中可用空气。这意味着可以在不增加涡轮入口（301,501）处的热气体温度（T1，T3）的情况下添加更多的燃料（12,13），并且功率增加。添加到冷却系统中的介质的量由控制元件（24,34,44）作为功率的控制偏差（Pset-Pact）的函数来控制。
