Method for regulating a distribution of fuel at predetermined burner stages of at least one burner of a machine during a steady-state machine operating mode, which has the steps: a) defining limiting values of various regulating variables, wherein the regulating variables comprise at least one evaluation variable for the stability of the combustion and an evaluation variable for the NOx content in the exhaust gas; b) acquiring and buffering the regulating variables using suitable measuring devices during the steady-state machine operating mode, wherein the fuel volume flows which are fed to the individual burner stages during the steady-state machine operating mode constitute known output variables; c) comparing the regulating variables buffered in step b) with the assigned limiting values, and if it is detected within the scope of these comparisons that at least one limiting value is exceeded, d) changing the fuel volume flow to a first burner stage by a predetermined value; e) renewed acquiring and buffering of the regulating variables using the measuring devices; f) evaluating whether at least one of the regulating variables buffered in step e) constitutes an improvement or worsening compared to one of the regulating variables buffered in step b); g) repeating the steps d) to f), until an improvement in at least one evaluation variable is acquired in step f); and h) carrying out the steps b) to g) for further predetermined burner stages of the burner, in particular for all the burner stages of the burner, wherein either, if no worsening of an evaluation variable is sensed in step f) after a fuel volume flow change has been carried out in step d), the fuel volume flow is changed, in the step d) which is carried out again, by a predetermined value in the same direction as in the preceding step d), or, if worsening of an evaluation variable is sensed in step f) after a fuel volume flow change has been carried out in step d), in the step d) which is carried out again the fuel volume flow change which is carried out in the preceding step d) is reversed. a) defining limiting values of various regulating variables, wherein the regulating variables comprise at least one evaluation variable for the stability of the combustion and an evaluation variable for the NOx content in the exhaust gas; b) acquiring and buffering the regulating variables using suitable measuring devices during the steady-state machine operating mode, wherein the fuel volume flows which are fed to the individual burner stages during the steady-state machine operating mode constitute known output variables; c) comparing the regulating variables buffered in step b) with the assigned limiting values, and if it is detected within the scope of these comparisons that at least one limiting value is exceeded, d) changing the fuel volume flow to a first burner stage by a predetermined value; e) renewed acquiring and buffering of the regulating variables using the measuring devices; f) evaluating whether at least one of the regulating variables buffered in step e) constitutes an improvement or worsening compared to one of the regulating variables buffered in step b); g) repeating the steps d) to f), until an improvement in at least one evaluation variable is acquired in step f); and h) carrying out the steps b) to g) for further predetermined burner stages of the burner, in particular for all the burner stages of the burner,
