See, size and seize the flame: the emotion project
Combustion Bay One.e.U. works currently in co-operation with FH Joanneum/Aviation on the development of an embedded optical sensor for real-time monitoring of the flame condition in aeroengine combustors.
This feasibility study is financed by the Take-Off programme from the Austrian Research Promotion Agency (FFG).
The very promising first results will soon be presented at the following conference:

Energy Innovation 2018: New Frontiers
CBOne is present at the Symposium EnInnov 2018 on Energy Innovation at TU Graz, from the 14th to the 16th of February.
Blueprint of the pressurised combustor used in the emootion project.
This year, two articles are presented:
- The first one is the project emootion, about the combined optic-acoustic precision monitoring of a flame in continuous flow machines. We show how this miniature monitoring system, developed at first for gas turbines can be used for atmospheric burners and heavy-use applications.
- The second topic is the project rePorT, about advanced burner design with integrated instrumentation. Instead of starting from an existing design - or conventional design - we show how a novel swirler shape was designed using additive manufacturing, and how this shape presents a lower pressure than a conventional swirler. This approach can result in significant gains in terms of weight and congestion. Combined to additional features such as the instrumentation, it simply leads towards better burners.

Better, safer, cleaner combustion
How can one drastically reduce fuel consumption? If the margin in terms of gains in efficiency at the main operation point is low (less than 5% using conventional combustion on most of the thermal facilities), the margin in terms of fuel savings at off-design operation is much greater.
Combustion technologies can be improved. Furthermore, the operating costs of thermal facilities can be reduced while improving safety. We address these affirmations with three flagship projects at CBOne: MethaNull, rePorT, and emootion.
At Combustion Bay One, we own these technologies, we fine-tune these and we regularly publish our results.
