METHOD AND DEVICE FOR REGENERATING AN ELECTRODE FOR IONIZATION MEASUREMENT IN A FLAME AREA OF A BURNER

The invention relates to a method for measuring an ionized regenerative ionization electrode in the flame region of a burner, the ionization electrode having a first alternating voltage of a first frequency and being supplied with a second alternating voltage of a second frequency, which is higher than the first frequency used for continuous operation, after the burner is started for a specific time interval Delta t. The invention further provides a device for executing the method. To this end, the device provides an ionization electrode which is arranged in the burner such that it can measurethe ionization current in the flame region during the operation of the burner. The device also provides a first alternating current power supply for generating a first alternating current of a firstfrequency and a second alternating current power supply for generating a second alternating current of a higher second frequency. During operation, a conversion device is connected with the second alternating-current power supply according to a preset standard. The invention avoids disturbances during the cold start of the burner due to long-term operation, measurement errors of the ionization current, and enables the regeneration of the ionization electrode to ensure that a further disturbance-avoiding control is carried out by accelerated heating during the cold start, at predetermined timeintervals and/or according to predetermined criteria.
