摘要： In a gas turbine group which consists essentially of a compressor (2), a first combustion chamber (3), a first turbine (4), a second combustion chamber (5) and a second turbine (6), the first combustion chamber (3) is configured as an annular combustion chamber. This annular combustion chamber (3) is operated by a number of premixing burners (11) which are distributed at the periphery. The first turbine (4) is designed in such a way that its exhaust gases have a temperature level which is above the self-ignition temperature of the fuel (13) used in the second combustion chamber (5). This second combustion chamber (5) consists of a burnerless, annular combustion space in which a number of vortex-generating elements (14) are integrated. The turbomachines, namely compressor (2), first turbine (4) and second turbine (6) are disposed on a rotor shaft (1), this rotor shaft (1) being supported in two bearings (9, 15).

摘要： In a method of operating a combined-cycle plant, valves (21) acting upstream of a high-pressure steam turbine (12) are completely closed in the event of load shedding. The gas-turbine group (A+8) is uncoupled from an intermediate-pressure/low-pressure steam turbine (11) in such a way that the gas-turbine group can go into island mode. In this case, the speed of the uncoupled steam turbine (11) is not greater than the speed of the gas-turbine group (A+8), and steam (16) in the flow path of a reheater (10a) belonging to the heat-recovery steam generator (10) expands freely through the intermediate-pressure/low-pressure steam turbine (11), in the course of which this expansion does not cause the speed of the gas-turbine group (A+8) to exceed its protective speed.
摘要翻译：在操作联合循环设备的方法中，在负载脱落的情况下，在高压蒸汽轮机（12）上游作用的阀门（21）完全关闭。燃气轮机组（A + 8）与中压/低压蒸汽涡轮机（11）分离，使得燃气轮机组能够进入岛模式。在这种情况下，不连接的蒸汽轮机（11）的速度不大于燃气轮机组（A + 8）的速度，属于该燃气轮机组的再热器（10a）的流路中的蒸汽（16）热回收蒸汽发生器（10）通过中压/低压蒸汽轮机（11）自由膨胀，在此过程中，这种膨胀不会导致燃气轮机组（A + 8）的速度超过其保护速度。
