Apparatus for igniting combustible fuel

摘要

Apparatus for igniting combustible fuel discharged from an outlet in a burner tube comprises a dielectric support within which are an ignition electrode and a ground electrode projecting beyond the support and which are spaced from one another a distance to form a gap which may be traversed by sparks generated by the ignition electrode. A fuel concentrator plate is carried by the ground electrode and partially embraces the ignition electrode adjacent the gap. The electrode support is mounted directly on the burner tube in a position to enable the concentrator plate to intercept fuel discharged from the outlet and concentrate the fuel in the zone of the gap.
