ABSTRACT:
In a method for operating a silo combustion chamber (A) of a gas turbine, this combustion chamber is equipped with a number of premixing burners (B), these burners being arranged so that they are subdivided in groups within the combustion chamber (A). At least one group is equipped with controllable premixing burners. Very high demands are made on the quality of the combustion during the operation of such a combustion chamber (A), particularly in the full-load range, in order to meet the stringent NO.sub.x emission regulations. For this purpose, the last group to be switched on is controlled at full load in accordance with the ambient conditions. A load control system also acts at part load. By this means, it is possible to prevent a fluctuation of the NO.sub.x emissions due to the varying ambient conditions.
