Continuous, real-time and on-line infrared imaging provides an important monitoring and control tool for a vast number of production and plant processes.
Die kontinuierliche Online-Infrarotabbildung in Echtzeit liefert ein wichtiges Überwachungs- und Steuerungsmittel für eine Vielzahl von Produktions- und Anlagenprozessen.
L’imagerie infrarouge continue, en temps réel et en ligne est un outil de surveillance et de contrôle essentiel pour un grand nombre de procédés de production et de transformation.
Infrared imaging improves process monitoring and control
T
hermal imaging technology supplied by Raytek has been crucial to the success of one customer whose business involves incinerating chemical industry waste.
To avoid any harm to the environment from
chemical waste, Raytek’s customer incinerates it in a rotary kiln at very high temperatures – up to 500°C. To increase combustion efficiency, the kiln
rotates at very slow speeds - typically 4 to 6 revs/h. Over time, the refractory brick protecting the kiln wall degrades and needs to be replaced. There is also the possibility that a single brick could fall, leading to a hotspot on the kiln shell and causing catastrophic failure. Taking action too soon will negatively impact
productivity, while waiting too long may put a high cost capital asset at risk.
Synchronising thermal imaging The customer opted to install a Raytek CS210 system which is able to synchronise thermal imaging at speeds as low as 2 revs/h. In addition, as these kilns are typically quite short (10-15 m), the CS210 is specifically designed to detect each potential refractory loss across the shell lengths by
providing a gapless sampling of pixels. The system helps process optimisation by detecting abnormal operating conditions such as faulty flame position, and reduces downtime by providing data to plan refractory replacement and avoid unscheduled maintenance. As the operational life of the refractory is
extended, each extra month on top of the original yearly maintenance saves the company €38,000.
Inspecting electrical equipment Meanwhile Raytek parent company Fluke has launched five new IR cameras that are designed to be powerful yet easy to use. Of most interest to process engineers are the Ti110 and T1125 models (Fig. 1). These are aimed at process engineers who need to troubleshoot, maintain and inspect electrical and mechanical equipment and components. Included among the cameras’ capabilities
are: IR Optiflex focus system for fast, easy to take, sharply focused, accurate images; IR-Fusion technology blends digital and IR images into a single image to precisely document problem areas; lightweight, designed for one-handed operation; rugged construction; multi-mode video recording to monitor processes over time and troubleshoot frame-by-frame; IR PhotoNotes annotation system
