D-VTA 200

For fossil fuel power plants

The D-VTA 200 Thermography Analysis System is developed, to work with all DURAG D-FS Furnace Sensors. Up to 8 Furnace Sensors can be connected to one D-VTA 200 System.

Together with the Furnace Sensor, the software delivers online temperature distributions directly from the combustion chamber.

The temperature range and the resolution are depending on the Furnace Sensor.

Depending on the application different analysing software modules are available.


Video Monitoring

  • Direct view of the combustion chamber
  • Visualisation during startup and operation

Thermography Analysis

  • Determine flame temperature and temperature distribution
  • Visualisation of FIREBALL and flame position


  • Enhance efficiency
  • Less tube ruptures, reduce downtime
  • Optimisation aid in case of changing load of fuels
