Video-based Thermography for Combustion Processes
The Thermography Analysis System
The system comprises the components of the video system plus the system computer with software modules. It operates as a spatial optical pyrometer on the basis of image data processing and offers, in ad-dition to the video system:
●● Temperature determination of each visible image point of the video sensor
●● Thermal analysis of the local temperature distribution
●● Temperature definition within freely definable measuring window and lines (ROI = Region of Interest / LOI = Line Of Interest).
●● Analysis of thermal samples to identify anom-alies in the combustion process
All data of the thermography system can be transmitted to the process control system via a standardized data interface.
Video Monitoring ThermographyThe Field Components
●● Ex-Sensor with adjustable support, flange, and gas-tight sealing
●● Ex-p control unit●● Connection to Control Room: Fibre Optic
Cable.
The Control Room Equipment
●● Linux based system computer for tempera-ture calculation, thermography presentation
●● Video monitor for online colour display
The Video System
The basic system comprises the above-men-tioned system components, without system computer. It enables visual monitoring through real-time colour video display.
The Video-based D-VTA 200 EX Thermography System
is a modular system for monitoring industrial high temperature processes. Intelligent sensors allow contactless, optical and thermal online ana-lysis of processes in the combustion chamber.Applications include:
●● Petrochemical Industry and Refineries:Thermal Crackers and HeatersSteam ReformersVisualisation of FlamesDetection of Hot Spots and local overheating
●● Steel Industry:Blast Furnace Top ControlCombustion Visualisation and Control in hazardous area.
The Sensors
have been specially developed for the harsh working conditions in hazardous areas (ATEX Zone 1). The sensor housing contains an indu-strial CCD camera. The slim water cooled sensor shaft (043mm) minimises the mechanical stress (abrasive dust) and the thermal influence on the sensor parts in the combustion chamber.The optical system is protected against mecha-nical and thermal damage by sapphire glass at the sensor tip, in addition to air purging. As no moving parts (no mirrors, prisms or motors) are located in the process-oriented area, the sensor achieves a high availability with minimum service requirement.
