Abstract: The present invention is a burner flame detector to detect a flame at a farthest end of a burner using a flame rectification rod. It comprises of a rod-element comprising of an inner electric-wire, an electrically insulating material surrounding the inner electric-wire, a metallic tubular outer rod protecting the insulating material and the inner electric-wire. The metallic tubular outer rod is electrically insulated from the inner electric-wire, and a flame rectification sensor is attached to the rod-element at the farthest end of the burner, which goes through the flame. The flame rectification sensor becomes exposed to a flame and sends a flame rectified signal to a controller, through the inner electric-wire.
