Abstract (en)

[origin: EP0926442A2] Oil or gas burner is controlled by an arrangement of a flame monitor (10), an ignition device (11), at least one fuel valve (13, 14) and a motor (12) of a combustion air fan. When there is a flame blow-off, switches are controlled so that the fan motor remains on to supply air to the burner while the ignition device and fuel valves are switched off. Preferably, the switching period is predetermined and can be adjusted. To ensure that the burner can be re-started, the devices are switched on in a given sequence, preferably automatically and immediately after the burner has been purged.
