  • Patent number: 9267686
    Abstract: An apparatus and method for monitoring the status of one or more pilot flames or of the main flame in a flare system. A collimator, quartz light tube, or other receiver is positioned near the combustion zone and receives an image which is transmitted via a fiber optic line to an analyzing sensor which is located at a safe distance from the flare system. The fiber optic line preferably extends through a pilot gas line, a flame front generator line, or other protective conduit so that the fiber optic line can be cooled and purged by pilot gas, instrument air, or other cooling gas media which is continuously delivered through the conduit.

  • Patent number: 9138791
    Abstract: A method and apparatus for installing a retractable thermocouple at the upper end of a flare stack for sensing a flare pilot burner flame. The apparatus comprises: a portable mounting structure; two pair of opposing drive wheels having non-metallic contacting surfaces; a first set of offset straightening rollers having non-metallic contacting surfaces for straightening the thermocouple in a first plane; and a second set of offset straightening rollers having non-metallic contacting surfaces for straightening the retractable thermocouple in a second plane different from the first plane.
