Abstract:
A control facility is provided for a burner system having a burner, actuators with which the supply of fuel and air to the burner is set, and an ionization electrode arranged in the flame zone. The control facility is equipped with a flame amplifier at the ionization electrode to generate an ionization signal and a positioning facility which, in control operation, positions a first actuator and regulates a second actuator by using a corresponding target value for the ionization signal. The positioning facility carries out a control operation in a first test step, it shifts the actuators toward a supply ratio corresponding to an air coefficient above the stoichiometric value of λ=1 and in so doing captures the ionization signal in a second test step, and it calculates a target value from this and from stored data in a third test step. Correction of drift therefore takes place.
