Flame or no flame? That is the question.
This very simple question should quickly find an answer. And an accurate one. Safety, process control, and emissions are at stake.
What was verified within tenths of a second with conventional fuels must be done faster with hydrogen. Besides: hydrogen is a flame that can hardly be seen with the naked eye.
In the framework of the FFG / Take-Off 2021 call, Joanneum Research GmbH has launched a project called crystAIr on the use of artificial intelligence to better monitor a flame. Piezocryst GmbH provides the sensors and Combustion Bay One is in charge of the experiments.

CBOne is currently involved in the planning of large-scale hydrogen facilities.
The proposal is to develop a R&D infrastructure with polytechnic capacity to study hydrogen machines operating in the MW range, over long duration tests, as well as their aggregates. These facilities would of course be open to industry and academia, and we would be their key partner in accessing and manipulating them.

An article summarizing 20 years of experience about CBOne's pulsation Technology and focusing on the very latest developments has been published in the International Journal of Turbomachinery for Propulsion and Power. To this point, we wish to thank the Board of the EVI-GTI Conference for their recommendation for journal publication.
CBOne developed a special actuator, able to generate with precision airflow modulations over the 0-6000 Hz range, with amplitudes achieving up to 150 dB SPL. The article describes into details:
- The siren technology
- The generation of a precision airflow modulation, for dynamic sensor calibration purpose
- The drive of flow dynamics, for laboratory applications
- The drive of thermoacoustics, for gas turbine applications

A compact, high temperature- and pressure-resistant probe was developed with success in the frame of the FFG / Take Off / emo(o)tion projects. This probe combines acoustic and optical sensors for a better description of the gas turbine combustion, in-situ.
The results of the probe are published in the International Journal of Turbomachinery for Propulsion and Power. The article is open access. The reference is:

Effective Solutions Against Particle Matter in Aviation

The new standard on particle matter called nvPM from the ICAO enters into force on the first of January 2020. From now on, a drastic reduction in particle matter (or soot) is required to get certification for the new aircraft engines.
CBOne and FH Joanneum / Aviation work together on the advanced combustion monitoring for aircraft engines including alert on soot formation in the frame of the "emootion" project
The ICAO is the International Civil Aviation Organization, a specialized agency of the United Nations in charge of setting the principles and techniques of international air navigation and of planning and developing international air transport to ensure safe and orderly growth. The acronym nvPM stands for non-volatile particulate matter emissions. It adds-up to prior standards defined for CO2 and NOx reduction in aviation.
CBOne participates in this effort to further push the limits of what is technically possible towards the soot-free burner. Read about our activities in burner design and advanced controls to improve the mixedness of the reactants, as well as our advanced monitoring techniques designed to detect soot production - so that it is then corrected within a comfortable safety margin.
