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.
