Components of the HTX Claus Thermal Reactor Thermocouple System The following listed components, referenced in this manual, are required for proper installation of the HTX. Failure to utilize these Components will reduce the life of the HTX and cause possible failure. -
Page 5: Pre-Installation
Pre-Installation 2.1 Transportation Care should be used in carrying, moving, and shipping the HTX thermocouple. A significant portion of the HTX is constructed of ceramic. Ceramics are very brittle at ambient temperature and can be damaged by mechanical shock. exclamat CAUTION The ceramic primary thermowell can easily break. -

“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 HTX assembly. G. If any parts appear to be damaged, contact Delta Controls immediately. Pre-Installation... -
Page 7: Nozzle Inspection
2.7 Nozzle Inspection 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. CAUTION exclamat Installing a thermocouple that is not properly sized for the nozzle and refractory can result in breakage or inaccurate measurements. - Page 8 C. Measure the Refractory Thickness with a measuring tape. Confirm that this distance matches the length of the straight portion of the HRW Refractory Thermowell as shown. (If the HRW thermowell is too short, the thermocouple will contact it during thermocouple insertion, causing it to break.

Page 9: Resolving Dimensional Problems
If the nozzle is too short, the thermocouple may contact the bottom of the refractory thermowell causing it to break. (See Note “D”, below). Contact Delta Controls to arrange for a thermocouple correctly sized for the installation. -

Installing the Thermocouple 3.1 Vertical Installation (For non-vertical installations do steps A - E, proceed to page 14.) A. Carefully set HRW Refractory Thermowell down onto the hole in the refractory. The collar of the HRW should rest flat against the refractory surface and the tip should extend about 1 inch (25 mm) beyond the refractory into the reactor vessel. - Page 11 C. Place the two soft compressible collar rings from the HNP Refractory Nozzle Packing Kit, having an inside diameter of 2.75 inches (70 mm) around the refractory thermowell collar. They should fill the gap between the outside of the refractory thermowell collar and the inside of the vessel nozzle.
- Page 12 E. Place enough of the rigid pressed 1.5 inches (38 mm) thick rings into the nozzle so that the top half of the top ring extends above the flange. If needed, remove or insert additional lower soft rings to obtain this fit. Rigid Pressed Rings Place and center the flange gasket on the vessel nozzle flange.
- Page 13 H. Have an assistant lift the thermocouple and turn it to a vertical position. The installer then grasps the unit by the top housing, permitting the unit to hang vertically plumb. With no assistance, center the primary thermowell over the center hole in the top packing ring and gently lower the unit into place on the flange.

L. Install instrument conduit, wiring and flush gas tubing as described below. After installation and before reactor startup, perform the Flush / Primary Thermowell Integrity Test on page 19. This will verify that the primary thermowell was not broken during installation, and that there are no problems with the flush connections. - Page 15 A. Install the HRW refractory thermowell and nozzle packing rings as described in steps A - E beginning on page 10. B. Insert an R Clip into the appropriate hole near the threaded end of one of the mounting bars. R-Clip This hole for 150#...

3.3 Wiring The conduit connection 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. Verify that the insulation on thermocouple extension lead wire is rated for 400°F (200°C) continuous service. -
Page 18: Flush Gas Connection
The use of nitrogen as a flush gas is strongly recommended. Ensure that the supply of flush gas is clean, oil free and dry. The Delta Controls Model HFS Flush Control Station provides a convenient and effective means to properly control the flush gas pressure and flow rate. Consult http://www.claustemp.com... -

3.5 Flush/Primary Thermowell Integrity Test The following procedure should be performed after thermocouple installation to identify installation problems, and to verify that the thermowell was not broken during installation. It should also be performed periodically (suggested weekly or bi-weekly) as routine preventative maintenance. A. -
