A method of operating a burner, in particular, a burner of a gas turbine, and a burner configuration include supplying an adjustable burner with fuel through a supply line. The fuel quantity is set by an opening of a control element as a function of a selected output of the burner. A calorific value of the fuel is determined, and the degree of opening is calculated and directly set using the output and the calorific value, resulting in a variable output control that is operationally reliable with respect to perturbations. A controller is connected to the control element having a selectable opening for setting the fuel quantity. In the controller, the degree of opening can be determined as a function of the output, the type of the fuel, and a pressure loss in the fuel supply line, and a corresponding signal can be transmitted to the control element such that the degree of opening is set.
