ABSTRACT:
In a method for operating a combustion chamber (4) equipped with premixing burners, under full load all the burners being operated under identical stoichiometric conditions, the burners are subdivided into at least two burner groups (1, 2 and, in the case of operating conditions below full load, the respective burner groups (1, 2) are operated with different air coefficients (.lambda.1, .lambda.2), that is to say at different flame temperatures (Tgr1, Tgr2). The operating range of the combustion chamber is widened considerably thereby.
