Video and Thermography Analysis System
The Thermography Analysis System
The thermography system comprises the compo-nents of the video system plus the system com-puter with software modules. It operates as a spatial optical pyrometer on thebasis of image data processing and offers, in ad-dition to the video system:
● Temperature determination of each visibleimage point of the video sensor
● Thermal analysis of the local temperature dis-tribution
● Temperature definition within freely definablemeasuring window and lines (ROI = Region ofInterest / LOI = Line Of Interest).
● Analysis of thermal samples to identify anom-alies in the combustion process
All data of the thermography system can betransmitted to the process control system via astandardized data interface.
Video Monitoring ThermographyThe Field Components
● Pneumatically operated retraction systemwith monitoring units for the cooling andflushing media, including integrated air accu-mulator
● Field control cabinet for control of the sen-sors, signal processing for the data and videotransmission via fibre-optic cable to the con-trol room.
The Control Room Equipment
● System computer for temperature calculation,thermography presentation
● Video monitor for online colour display
The Video System
The basic system comprises the above-men-tioned system components, without system com-puter. It enables visual monitoring through real-time colour video display.
The D-VTA 100-10 Video and Thermography System
is a modular system for monitoring industrialhigh temperature processes. Intelligent sensorsallow contactless, optical and thermal onlineanalysis of processes in the combustion chamber.Applications include:
● Burning analysis and slag monitoring in pow-er plants
● Visualization of flame post combustion cham-bers and flame front monitoring in waste in-cineration plants
● Monitoring ore calcination and hazardouswaste disposal in the chemical industry
● Annealing and pusher furnace monitoring inthe steel industry
● Scale formation and melting charge control inthe glass industry.
The Sensors
have been specially developed for the harshworking conditions in industrial combustions. The sensor housing contains the special boro-scope as optical system, or the videoscope andthe industrial CCD camera. In this design all elec-tronic components are operated outside the kilnarea, in the cooled camera housing. The slim, air or water-cooled sensor shaft(Ø 43mm) minimises the mechanical stress (abra-sive dust) and the thermal influence on the sen-sor parts in the combustion chamber.The optical system is protected against mechani-cal and thermal damage by sapphire glass at thesensor tip, in addition to air flushing. As no mov-ing parts (no mirrors, prisms or motors) are locat-ed in the process-oriented area, the sensorsachieve a high availability with minimum servicerequirement.
