Abstract
In a method for operating a sequentially fired gas-turbine group, during starting the inlet guide row in the compressor (12) is opened up to a maximum up to the pumping limit of the same. The ignition (2) of the first combustion chamber (13) takes place below the rated speed during idling of this gas-turbine group with the opening of the inlet guide row remaining constant, then the inlet guide row is opened further until the rated speed is reached during idling. The ignition of the second combustion chamber (15) takes place during operation at this rated speed and with the opening of the inlet guide row remaining constant. The inlet guide row is then accordingly opened further at constant rated speed until full load (6) is reached.
