Abstract
An ignitor spark indicatoris described that monitors RF signals within a flame rodlocated near a spark rod. The signal from the flame rodis processed to provide a waveform that indicates when electrical arcing is occurring. The indication when arcing is occurring is also provided to flame-detecting equipment. The flame-proving deviceonly operates when the arcing is not produced so that the flame-detecting devicedoes not confuse the arcing with a flame reducing the false positive determinations.
