detection. If power is lost during a running cycle, the control will NOT go off on safety and it will normally re-energize the burner after power is restored. additional control. For example, a steam boiler with a domestic hot water coil will normally have an aquastat wired to the low voltage terminals on the primary control.Get a Quote
Flame Safeguard System Selection Gui
the ﬂame detector detects the abnormal condition of combustion ﬂame, transmits the signal to the burner controller to close the safety shutoff valves, and prevents the ﬂow of fuel into the combustion chamber. If the ﬂame detector or burner controller has caused a failure, the system has a safety circuit function to operateGet a Quote
heating - Combi boiler doesn't realise it's already lit .
19 = "detection electrode" 20 = ignition electrodes. See manual. A07 = flame detector. A09 = flame detection circuit. A10 = flame indicator LED - I'd check this is "on" after 5 seconds of successful ignition. Don't rule out other causes, boilers shut themselves down for lots of reasons, maybe the flue is iced up or the water pump isn't operating.Get a Quote
Causes for Flame Failure in a Boiler and Operator Action .
Maintaining a good flame in a boiler is the key to a good boiler performance. Unstable flame is always a threat for boiler furnace explosion, which can lead to a large outage of boiler and loss. There are many causes that can contribute to boiler flame failure. Hence it has become a practice of all boiler designers to interlock purging the boiler with boiler start-up.Get a Quote

How Does a Furnace Flame Sensor Work? | Hunk
Heat of the Flame. Flame sensors, whether they are used in a home furnace or on a large industrial boiler, indicate the presence of a flame and are part of the safety circuit. If the flames go out and the furnace or boiler continue to feed the unit with fuel, a catastrophic explosion could occur. The flame sensor sends an electrical signal to a central controller.Get a Quote
