Abstract: In a method for regulation a gas turbo-generator set operated with sequential combustion, the fuel quantity necessary for operating the first combustion changer is first controlled as a function of a pressure prevailing at the outlet of the compressor. The ratio between this fuel quantity and this pressure is continuously updated by means of a factor reproducing the deviation of a temperature at the inlet into the first turbine from the desired value of this temperature. A fuel quantity necessary for operating the second combustion chamber is controlled as a function of a pressure prevailing at the inlet into the second turbine, and the ratio between this fuel quantity and this pressure is likewise continually updated by means of a factor reproducing the deviation of the inlet temperature into the second turbine from the desired value of this temperature. The inertias in the system are neutralized by means of this pressure backup regulation.

Abstract: In a method of operating a gas-turbine group, an exhaust-gas flow (9) of the gas-turbine group is admitted to a heat-exchange stage (14, 18), through which a liquid fuel (12) and a water quantity (16) flow. The thermally processed media (12, 16) are then brought together, whereby an emulsion (19) is formed, and this emulsion (19) is used to operate a burner of a combustion chamber. In this way, the spraying of this very hot emulsion (19) into the combustion air ensures good mixing.
