Modell based distributed fiber-optic high-temperature measurements compensating and detecting deposits

Continuous deposits on metallic pipe walls are a worldwide problem in highly industrial plants. They cause gradual blockage that can only be eliminated by complex, cost-intensive maintenance and cleaning processes. Too late maintenance results in poor product quality, prolonged loss of operation and earnings or even in sustainable damage to the plant.

The project detect.it focuses on the development of a novel, model-based measurement method for distributed temperature measurement in high temperature applications based on FIMT technology (Fiber in Metall Tube). One major goal is to study the influence of sensor coatings and deposits in and on pipe walls in order to improve process monitoring. On the other hand, deposits themselves shall be detected to further schedule and optimize maintenance intervals. In contrast to common punctual measurements, the novel glass-fibre-based methods will provide fine spatial temperature distributions with high temperature resolution.

Within the project measurement methods and innovative coatings will be investigated thoroughly. Based on the outcomes, a model-based measuring method will be developed that takes spurious influences such as the non-ideal thermal coupling of the thermal sensors to the pipes into account and provides associated correction factors. Furthermore, a concept for the detection of pipe deposits will be developed.

Applications can be found in many industries such as ethylene cracking processes at 900°C or in the production of alternative energies (e.g. wood chip combustion).The developed methods can help to increase process efficiency and the quality of the product. Furthermore, heating and CO2 demand can be reduced in thermally controlled processes.

**The project detect.it is partially co-funded by the European Commission under the European Regional Development Fund (www.efre.gv.at)  according to article 4 ERDF and the county of Lower Austria (www.noe.gv.at).
