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.
