Method and apparatus for improving exhaust gases of a gas turbine installation

A method for operating a gas turbine installation and an apparatus for carrying out the method, particularly for a vehicle gas turbine installation, in which the air is compressed and heated up by utilizing the exhaust gas heat of the gas turbine installation, fuel is combusted under supply of compressed air with an excess of air, the resulting gas is thinned out and cooled off by admixture of compressed heated air, and the produced gas is then permitted to expand for producing an output; a more or less large quantity of non-preheated air is thereby admixed to the preheated primary air prior to the entry into the combustion zone at least within the lower partial load range, preferably as a function of load, in order to control the temperature in the combustion space.
