D-VTA 200 Thermography System for Combustion Processes

D-VTA 200 Thermography System for Combustion Processes

The Video-based D-VTA 200 Thermography System is a modular system for monitoring industrial high temperature processes. Intelligent sensors allow contactless, optical and thermal online analysis of processes in the combustion chamber.

The sensors have been specially developed for the harsh working conditions in industrial combustions. The sensor housing contains the special boroscope as optical system, or the videoscope and the industrial CCD camera. In this design all electronic components are operated outside the kiln area, in the cooled camera housing. The slim, air or water-cooled sensor shaft (Ø 43mm) minimises the mechanical stress (abrasive dust) and the thermal influence on the sensor parts in the combustion chamber. The optical system is protected against mechanical and thermal damage by a sapphire lens at the sensor tip, in addition to air flushing. As no moving parts (no mirrors, prisms or motors) are located in the process-oriented area, the sensors achieve a high availability with minimum service requirement.


Applications

  • Detection of the Temperature Distribution in side combustion chambers; analysis of unbalanced combustion processes
  • Burning analysis and slag monitoring in power plants
  • Visualization of flame post combustion chambers and flame front monitoring in waste incineration plants
  • Visualization and temperature distribution analysis of grate based firing systems, f.e. biomass and co-firing
  • Monitoring ore calcination and hazardous waste disposal in the chemical industry
  • Annealing and pusher furnace monitoring in the steel industry
  • Scale formation and melting charge control in the glass industry
