Describe what a flame proving device is

WebA flame is a zone within which the combus-tion reaction occurs at a rate that produces visi-ble radiation. A flame front is the contour along which the combustion starts — the dividing line between the fuel-air mixture and the combus-tion process. In stable flames, the flame front appears to be stationary. The flame moves WebReliable "Flame Sensing" is an important feature of modern gas ignition systems. Knowing when the flame is lit (and importantly, when it is not lit) is the key to safe operation. This is accomplished by passing a small amount of current through the flame to ground. The control detects changes in current caused by the presence or absence of a flame.
