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。

摘要： A method for axial thrust control of a gas turbine, and a gas turbine with a device for controlling axial thrust are provided. A gas turbine, with regard to aerodynamic forces and pressure forces, which exert an axial force upon the rotor, is configured such that at no-load and low partial load it has a negative thrust, and at high load it has a positive thrust. In order to ensure a resulting positive thrust upon the thrust bearing within the entire load range of the gas turbine, an additional thrust is applied in a controlled manner. The additional thrust for example can be controlled in dependence upon the gas turbine load. The resulting thrust force at full load is consequently less than in the case of a conventionally designed gas turbine without thrust balance.

摘要： A gas turbine (1) includes a combustion chamber (2) followed by a stator airfoil row (4) defining a plurality of guide vanes and separated by the combustion chamber (2) by a first gap (5), and a rotor airfoil row (6) separated by the stator airfoil row (4) by a second gap (7). The stator airfoils (15) of the stator airfoil row (4) are connected to guide vane boxes (17) collecting a cooling fluid (A) and injecting it through nozzles (20) in the second gap (7) to make it to enter rotor airfoil inlets (23). The guide vane boxes (23) are provided with passages (30) connecting a zone (31) upstream of the guide vane boxes (17) to a zone (32) of the second gap (7) downstream of the guide vane boxes (32). Moreover, the mouths (3) of the passages (30) facing the rotor airfoil row (6) are closer to a hot gases path than the nozzles (20).

摘要： The invention describes a device for separating dust and dirt out of flowing media. A curved flow path (1) is imposed on the flow (21), and heavy foreign bodies are separated out of the main flow by centrifugal force. The partial stream required to carry away the foreign bodies is aftertreated in a filter (11) and returned in purified form. Unlike with conventional filters, which have to process the entire flow of media, pressure losses during the separation of dust are minimized, and on the other hand no medium is lost for removing the dust load.

摘要： In an axial-flow compressor, the appliance for extracting secondary air using a peripheral extraction slot which is at least partially configured as a diagonal diffuser is such that means which make it possible to utilize the kinetic energy of the peripheral component of the flow velocity are arranged in or directly at the extraction slot (4). These can, for example, be a mini-cascade (7) integrated in the extraction slot (4) or an extraction slot (4) which is designed as a diagonal diffuser (8) and merges into a volute (9), the volute (9) opening directly into the extraction tube (6). The total pressure loss is minimized and the efficiency of the installation is increased by these arrangements.
