Method for controlling the air ratio of a burner

摘要

The method involves disconnecting an ignition electrode (102) by a medium for generating the ignition voltage (104). An electrical signal (115a) is sensed to an ionization electrode (103) and the signal is derived dependent on an air ratio in response to the electrical signal. Another electrical signal (115b) is sensed to the ignition electrode and another signal dependent on the air ratio is derived in response to the latter electrical signal. An independent claim is included for a burner, particularly oil or gas burner with an ignition electrode.
