N2 Applied’s partner – SBI GmbH – is in the process of designing a robust prototype for field testing at Cambi AS Hamar in Norway in April/May 2014. The development work is taking place on SBI company premises in Hollabrunn, Austria. Rune Ingels visited Hollabrunn this week to work with the team and to discuss issues and possibilities. 

The prototype will be equipped with a power supply with an energy efficiency of up to 95%.  The arc current will be high frequency pulsed in order to automatically re-ignite and survive disturbances in air flow and air quality. Air flow controllers using working air is tested together with safety features to protect the unit against any unforeseen event.

A trade-off.

The Team (read Roman Kettler) has been working day and night to get all items ready in time for the first bench testing this week.  The new power control proved to give the required robustness for the arc.  The arc is re-igniting at all relevant pressures and air flows.  It was able to handle air pulses as well as skewed air flows and jets.  For the first time we could also reverse the polarity of the arc and still be able to run and produce NO/NO2.

The prototype will be equipped with the NO/NO2 analyzer, and will also serve as a research unit for the future development.  

Rune returned to Norway – enthusiatic and forward leaned.  Still R&D – but slowly turning into real application.  A lot to do and little time!  

As it should be/always is.
