A METHOD FOR IGNITION OF AN OIL BURNER AND ELECTRONIC IGNITION CIRCUITRY FOR OIL BURNERS

摘要

Electronic ignition circuit for oil burners, for generating temporally spaced sparks. The electronic circuitry comprises circuitry for producing temporally spaced sparks with a spacing not corresponding to a half-period of the AC mains frequency or of a multiple of the AC mains frequency. The circuitry may be used in a method for ignition of an oil burner forming part of an oil burner system, where said oil burner comprises electronic circuitry for producing a first sequence of temporally spaced sparks for ignition of the oil. According to the method, the electronic circuitry is adjusted to subsequently produce a second sequence of temporally spaced sparks if it is detected that the ignition results in acoustic resonance in the oil burner system using said first sequence of temporally spaced sparks.
