Patent ID: 7335015

Claim:
A method for controlling or regulating a burner to which a defined air quantity and fuel quantity are fed, the exhaust gas formed during the combustion being fed to a sensor, and the actual value detected by the sensor being compared with a desired value, and a control deviation being obtained from the difference between desired value and actual value, which control deviation is converted into a control variable which is independent of the burner power, characterized in that a power-dependent control variable is generated from the power-independent control variable and from burner-specific parameters which are determined during setting of the burner for the respective power points of the burner, and in that the power-dependent control variable is converted into a control signal in order to influence the ratio of the air quantity to the fuel quantity, characterized in that the power-independent control variable which was last present at a steady-state burner power is maintained in the event of an adjustment to the burner power and is taken into account when determining the power-dependent control variable, and characterized in that the power-independent control variable is normalized in such a manner that a percentage change in the air density is compensated for by an identical percentage change in the control variable.
