摘要
A method for detecting the operation of a burner uses the rectifying effect of the burner flame, when an alternating voltage is applied between the burner (1) and an electrode (2). A control device (18) is connected to the primary of an isolating transformer (6) which receives a high frequency alternating voltage from a generator (7). The current rectified by the flame provides dumping of the circuit at the secondary of the transformer which is used to detect the presence of a flame. An igniter (25) may be connected to the same electrode of the burner via an element (28) whose resistance varies with the voltage.
