Kurzfassung englisch:
The growth of deposit layers in process furnaces is an inevitable problem in industrial processes. Monitoring this process in a non-invasive, model-based manner can help to improve process quality and extend runlength between maintenance cycles. A key parameter in this context is the outer pipe wall temperature. Contrary to common spot temperature measurements, we propose fiber optic sensors (so-called Fiber In Metal Tube, FIMT) allowing a high spatial resolution. The exact location of the FIMTs is decisive for the sensitivity of the temperature measurement. Since our test facility is a high-temperature furnace, the optimal FIMT position cannot be evaluated experimentally in the usual manner. Therefore, we present a model-based approach taking into account the thermal characteristics of the deposit layer, the turbulent hot air flow inside the chamber and also imperfections of the FIMT installation such as non-ideal thermal contacts. 2D FEM simulations show the temperature distribution around the pipes and are used to indicate best positions regarding the optimal mounting of the sensors.
