Abstract
A method for operating a gas turbine plant utilizing sequential combustion is provided. The gas turbine plant includes a compressor for compressing inducted combustion air, a first combustion chamber for combustion of a first fuel by utilizing the compressed combustion air, with a first turbine which is connected downstream of the first combustion chamber, and a second combustion chamber for combustion of a second fuel by utilizing the gases which emerge from the first turbine, with a second turbine which is connected downstream of the second combustion chamber. The method provides quick running up with simultaneously low emissions and homogeneous distribution of the turbine inlet temperature is achieved by the second combustion chamber being completely shut down for achieving a low partial load mode of the gas turbine plant.
