Harmen Kielstra has been Managing Director of CelSian Glass & Solar since September 2016.

As Managing Director, he is leading the transition from governmental research institute to glass engineering consultancy.

Mr Kielstra will be presenting the ‘Application of advanced sensors in the glass industry’.

It will look at the availability of advanced sensors, next to thermocouples, in industrial glass melting furnaces is a prerequisite for further automation in the glass manufacturing industry.

It explains that these advanced sensors should provide real time, quantitative information about the quality of the glass melt, the position and thickness of the batch and foam layers, the key parameters of the combustion process, the energy flows in the furnace and the status/integrity of the furnace lining (refractories and insulation).

In the presentation a survey will be given of available measuring techniques, like in-line chemical analysis of raw materials, redox sensors of the glass melt, laser sensors for combustion gases and batch monitoring cameras.

The latest development regarding LIBS technology will also be discussed in more depth.
