D-VTA 200

For the cement industry

The D-VTA 200 Thermography Analysis Software delivers online temperature distributions directly from the kiln and clinker cooler.

Special software modules for the cement process, like a free lime prediction, are available. 

Applications

Video Monitoring

  • Live Image of sinter zone and clinker cooler.
  • Visualisation of clinker formation and clinker balls

Thermography Analysis

  • Clinker and flame temperature
  • Flame shape and ignition points

Benefits 

  • Stabilization of product quality
  • Reduce refractory wear in kiln and cooler
  • Free lime prediction
  • Optimisation aid for alternative fuels
  • Detection of „snowman“ and „red river“
