Flame sensor for oil heating burner - has transparent window in chamber floor for passage of flame light to probe

摘要

The burner for heating oil comprises an outer tube for combustion air feed in which a probe for a flame control is located. An inner coaxial chamber in the tube encompasses the burner nozzle. A whirling disc closes the chamber outlet aperture. This disc has a central hole for the nozzle flow. The floor (4) opposite to the whirling disc (2) in the inner chamber (6) is made of transparent material. This allows adequate light from the burner flame to reach the flame control probe.
