FLAME RECTIFICATION Or FLAME SENSING - Ferguson HVAC
heatingcooling.fergusonhvac.comMar 21, 2017 · What Is Flame Rectification? The flame sensor is mounted on the burner box and is enveloped in flame. Current flows from the sensor though the burner head to ground. Because the sensor is smaller then the burner head, current flows in one direction. The resulting pulsating dc current is considered rectified. The presence of pulsating dc
