La Belle Equipe

The traditional "Kleeblattlauf" took place on the 22d of June. As usual, this event closures the academic year. It is a fest, where sports first take place, and then comes relaxing and enjoying the time and the company of fellow people and colleagues.

The running squad mit number 284. 35mins25', record broken, but OK the track has been shortened...

Let us change the order: from right to left, Mrs Paulitsch (project rePorT), Mr Stuetz (alumnus, Siren-3G), Mrs Moosbrugger (MethaNull, emootion) and Fabrice Giuliani. The picture was taken by Mr Mader (alumnus, Siren-E) and Mr Pfefferkorn (alumnus, emotion, rePorT) is somewhere on the field maybe with Mr Andracher from FH Joanneum (consortial partner, emo(o)tion).

I would like to pay tribute to the fellow runners, and to those who made and make Combustion Bay One a nice place to work in.

ASME Turbo Expo 2017: Make Combustion Great Again!!!!

We are honoured to be part of the renowned ASME Turbo Expo 2017. This year's ASME conference will be held from June 26 - 30 in Charlotte, North Carolina. CBOne will present its latest research about a novel probe concept for advanced combustion monitoring and about a method for the improvement of impaired combustion conditions at off-design operation points.

Charlotte likes it hot !!!

For the improvement of impaired combustion conditions a robust acoustic driver (called siren) is used, being able to perform well and last long in an industrial environment. The previous figure suggests how the siren could be implemented on a real power gas turbine.

Combustion Bay One is five years old!

CBOne was officially opened on the 27th of March 2012. At that time we were rushing a bit to get the first contract officially signed with the official stamp of an engineering office!

Five years. Fifteen people directly involved. Eleven publications. Twelve presentations in renowned international congresses and conferences. Two proprietary technologies... See all counts for all what can be counted in the detailed section.

Many students. Many slides. Many km. Many many contacts and a happy few… who turned eventually into our dear Clients! The small "r" in cont(r)act is not trivial. A lot of sweat. A lot of humor, sometimes bittersweet, often good. A lot of smiles. A lot of laughs. 

We thank good luck. We appreciate the wide spectrum of things done. 

I rise my glass. Not only to these five years, but also to a bright future. 

To CBOne. To the people who made it. Cheers!

Fabrice Giuliani, CEO

The air we breathe

A breathtaking picture in the Parisian outskirts during the pollution peak with particulate matter in Dec. 2016

Normally, at this time we publish our Season’s Greetings. However, this December’s headlines are about remarkable pollution peaks observed during week 49 (6-9.12.2016) in Mailand, Brussels, London and Paris. This time, the concentration in particulate matter was alarming. The exceptionally nice weather and its absence of wind just made things worse.

The alert for most large cities in Europe is given when a concentration in particle matter with size smaller than 10 microns (PM10) above 50µg/m3 is achieved. A sub-category of it is the group of particles smaller than 2.5 µg/m3. These are known to deposit in our breathing cavities and organs, and possibly interact with our blood. The WHO recommends a maximum concentration of PM2,5 of 10µg/m3. 

Quoting the European Environment Agency (EEA), "air pollution remains the single largest environmental health hazard in Europe, resulting in a lower quality of life due to illnesses and an estimated 467 000 premature deaths per year".

Roughly one third of these particles come from industrial combustion processes. And this is a figure one can reduce, namely with better combustion. This is what we do at Combustion Bay One.

Support CBOne by helping us to promote and deploy our MethaNull technology. We can bend these numbers. We can breathe a cleaner air. Complete combustion will reduce drastically the production of particulate matter. This email address is being protected from spambots. You need JavaScript enabled to view it.

GTI2016: Filling in the missing link on combustion monitoring between laboratory and real gas turbine

Meggitt Sensing Systems and Combustion Bay One work together on monitoring of combustion dynamics in gas turbines. The latest progress will be presented at the conference GTI2016 in Berlin (presentation no. 026). This presentation focuses on the latest efforts made to automate the recording and documentation of even small changes of the burner operation conditions, and correlate these to the dynamic measurements.

Date and location: GTI2016, Berlin, Thursday 29th September 2016 at 11:30 

The focus is put on the precise combustion control using CBOne's burner test rig and methods, and detailed description of the latter using MSS' measurement chain including fast-pressure sensors and accelerometers, as well as associated data acquisition systems.
