Furnace outlet temperature measurement

All critical factors under control

During the refining process the interior of the tubes becomes congested with baked-on coke, mostly just before the bend. As a consequence, more heat is required on the furnace tubes to maintain charge temperatures. Through time this build-up may even completely plug the tubes. Our skin thermocouples monitor the temperature at the most vulnerable spots.

These coke particles are also very abrasive. They fly at high speed through the tubing system towards the outlet causing extreme wear and tear on the inside walls. The outlet thermowell tip must therefore be protected with a wear-resistant layer. Among the choices available we offer bar stock Alloy 6B.

Thermowell tips are Eutalloy or a stellite layer. All wells are made to customer specifications.

Most thermocouples used are types K and N.
