  • Page 3 Components of the HTP/HTX Claus Thermal Reactor Thermocouple System Referenced in this Manual The following listed components are required for proper installation of the HTP/HTX. Failure to utilize these components will reduce the life of the HTP/HTX and cause possible failure.
  • Page 4: Shipping Preparation, Storage & Handling

    Shipping Preparation, Storage & Handling Transport Care should be used in carrying, moving, and shipping the HTP/HTX thermocouple. A significant portion of the HTP/HTX is constructed of ceramic. Ceramics are very brittle at ambient temperature and can be damaged by mechanical shock.

    “loose”. If loose, the thermocouple is broken and must be repaired prior to installation. The shipping pipe and the custom built protective shipping carton are reusable and may be saved for reshipment or storage of the HTP/HTX assembly. g. If any parts appear to be damaged, contact Delta Controls immediately. Page 5...
  • Page 6: Inspect The Nozzle

    Inspect the Nozzle Because the “as-built” dimensions of the refractory and nozzle can (and often do) differ from the design specifications, it is important to verify these dimensions before installing the thermocouple. Installing a thermocouple that is not properly sized for the nozzle and refractory can result in breakage or inaccurate measurements.
  • Page 7: Resolving Dimensional Problems

    HRW Refractory Well to extend approximately 1 inch (2.5 cm) past the refractory hot face. If these conditions are not met, the result may be inaccurate measurement and/or breakage due to mechanical interference or thermal shock. Contact Delta Controls arrange...
  • Page 8 In general, this gap will not close up at operating temperatures. The thermocouple must be re-sized to account for the gap. Contact Delta Controls to arrange for a thermocouple that is correctly sized for the installation.

    Installing the Thermocouple Vertical Installation (For non-vertical installations do steps 1-5, proceed to page 14.) Carefully set HRW Refractory Well down onto the hole in Double-check for proper clearance prior to thermocouple the refractory. The collar of the HRW should rest flat insertion by measuring from the bottom of the refractory well up against the refractory surface and the tip should extend to the flange face.

  • Page 11 Have an assistant lift the thermocouple and turn it to a vertical Note that the thermocouple is heavy position. The installer then grasps the unit by the top housing, and the ceramic element well may be permitting the unit to hang vertically plumb. With no assistance, center the element well over the center hole in the top insulating easily broken.
  • Page 12 11. Install instrument conduit, wiring and purge gas tubing as described below. After installation and before reactor startup, perform the Purge / Element Well Integrity Test on page 17. This will verify that the element well was not broken during installation, and that there are no problems with the purge connections.
  • Page 13: Non-Vertical Installation

    Non-Vertical Installation In non-vertical installations, insertion of the thermocouple unit can be difficult. The installer must attempt to support the full weight of the thermocouple unit while fully inserting it into the centerline of the nozzle insulating materials at the appropriate angle without allowing the weight of the unit to impart side-loads on the element protective well.
  • Page 14: Non-Vertical Installation - Using The Hmb Mounting Bars

    Non-Vertical Installation - Using the HMB Mounting Bars 1. Install the HRW refractory well and nozzle insulation rings as described in steps 1-5 beginning on page 9. 3. Place the threaded end of the mounting bar into a 2. Insert an R-Clip into the appropriate hole near the vessel nozzle flange bolt hole as shown.
  • Page 15: Wiring

    Wiring • The conduit connecting to the terminal enclosure should be equipped with a union and a flexible conduit for ease of maintenance and to reduce strain on the terminal enclosure. • Ensure that the insulation on thermocouple extension lead wire is rated for 400°F (200°C) continuous service. •...
  • Page 16: Purge Gas Connection

    Purge Gas Connection The use of nitrogen as a purge gas is strongly recommended. The Delta Controls Model HFS Purge Control Station provides a convenient and effective means to properly control the purge gas pressure and flow rate. Consult Document http://claustemp.com/00-hfs01.pdf...

    Such breakage is sometimes cause by shifting of the refractory due to thermal expansion. When properly installed, the thermal well can withstand some shifting of the refractory, but large shifts can cause failures.
