Gas burner regulation system

摘要

The regulation system uses an ionisation electrode (4) providing an ionisation signal dependent in the temp. or lambda value of the combustion, supplied to a regulation circuit (9) for comparison with a reference value, for adjustment of the air/fuel ratio for the burner (1). A calibration cycle is initiated at regular intervals or after a defined operating time, with the lambda value reduced and the corresponding ionisation signal measured. The max. values of the ionisation signal are stored for correction of the required value for the regulation.
