As part of the ELECTRA project, researchers from Chalmers University of Technology and SINTEF carried out a successful measurement campaign at SINTEF’s high enthalpy plasma torch test chamber.

During the visit, Adrian Gunnarsson and Klas from Chalmers installed two radiation probes designed to capture different aspects of the plasma torch emissions. One probe measures radiation in a very narrow angle, effectively probing the plasma along a single line of sight, while the other captures a wider view, providing an overall picture of the torch’s radiation intensity.

The tests showed promising results — the probes could clearly detect variations in the torch’s parameters, such as changes in electrical power input and the magnetic field used to control the plasma arc. These measurements will now be combined with data from the cooling water system to better understand the heat uptake and overall energy efficiency of the plasma process.

This campaign marks another step forward in ELECTRA’s efforts to advance high-temperature plasma technologies for sustainable industrial applications.
