EnInnov 2020: From the Dawn of Mankind to the Digital Fire

Rare and precious 

Rabelais wrote in "Gargantua"  that what distinguishes Man from other creatures is its ability to laugh. If this say has recently been proven wrong - apes laugh, maybe bees too - one so far unchallenged trademark of Mankind is our ability to make fire! However, the fact that the extensive use of fire has a negative impact on the climate is nothing to laugh about.  The decarbonisation of our society is an ongoing process and this is a very good thing.

Fire will therefore become rare 

- and precious.

Digitalisation for Decarbonisation

While decarbonisation takes place in an ordered manner (energy, transport, heating...), some specific sectors will take longer to decarbonise because they need high temperatures, a lot of power and before all a safe process. Combustion Bay One e.U. focuses on the improvement of these thermal facilities (energy, process engineering, metallurgy, aviation) in order to improve the efficiency on the one side and reduce the environmental impact on the other side, until climate-friendly alternatives can be deployed. The proper management of the remaining fossil resources shall also be kept in mind. In a word, we have to buy time. 

In a hypothetical future world where combustion is indeed rare and precious, we intend to become the Guardians of Fire. Any improvement in combustion technology is therefore good to take. Recent progress shows that purely mechanical thermal systems have reached their limits. New progress involve better sensing and faster actuation, which is not straightforward in the direct proximity of a flame. Still, this is what we do, this is the digitalisation of combustion technologies.  These are the missions of Combustion Bay One e.U., an Engineering Office specialised in Advanced Combustion Management.

EnInnov 2020!

We will be present at the Energy Innovation Conference 2020 at TU Graz (12-14.02.2020) where we present commonly with FH Joanneum our progress in precision monitoring of combustion processes:

The project emootion is financed by the BMVIT and the FFG in the frame of the Take-Off program, contract 861004. This is also the occasion for us to reveal our latest S3R ignition system (S3R=Safe, smooth, smart and reliable) as well as our newest pressurised combustion test rig.

The emootion project at the ASME Turbo Expo 2020

This year's edition marked the TRL4 achievement of the emootion technologies, including our progress in dynamic flow control, and the validation of a combined acoustic-RGB optical probe describing the flame.

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:
