Abstract: A system having a flame rod assembly for operation in a high temperature pilot burner. The assembly is designed for operation in temperatures from about ?40 to 1100 degrees C. The system may operate in inclement weather involving high speed winds and significant amounts of moisture and rain to hurricane storm force levels and rates. The system incorporates an electrical apparatus which may provide flame sensing and ignition via the flame rod assembly incorporating a quick drying insulator around a rod of the assembly to ensure proper operation of the electrical apparatus.

Abstract: An assembly for a rapidly-drying rectifying flame rod, having an insulator sleeve. The assembly may further incorporate a mechanical coupling attaching the flame rod to an end part which in turn may be hermetically coupled to an insulator. The insulator may be hermetically coupled to a conduit which may be hermetically coupled to an elongated tube. A conductor may go through the tube, conduit, insulator and end part. The flame rod may be connected to the conductor via the mechanical coupling and end part. A sheath having sealing and electrical insulating properties may be formed over at least a portion of the components. Hermetic couplings may be made with ordinary blazing or welding. The couplings may instead be made with high temperature brazing or welding which can withstand temperatures equal to or greater than 1500° F. At these temperatures, the sleeve on the flame rod and the sheath may be eliminated.
